Beretania Street, Suite 400 • Honolulu, Hawaii • 96826 • (808) 946-2277 10470-01 October 25, 2021 Ms. Marisa Valenciano, Planner Planning Department County of Kaua‘i 4444 Rice Street, Suite A473 Līhu‘e, HI 96766 Subject: Supplemental Information St. Catherine Preschool Use Permit and Class IV Zoning Permit Kapa‘a, Kaua‘i, Hawai‘i TMK: (4) 4-6-015:058 Dear Ms. Valenciano: We understand that the subject project will go before the Kaua‘i Historic Preservation Review Commission (KHPRC) at its meeting scheduled for Thursday, November 18, 2021. As a follow up to our phone call and your email both dated August 31, 2021, the following information is being provided in support of the upcoming meeting. SHPD HICRIS HRS 6E-42 Review To our knowledge, this project has not been routed to the State Historic Preservation Division (SHPD) in conformance with HRS Chapter 6E-42 historic preservation review requirements prior to the current application submittal. KHPRC October 2019 Meeting It was noted that a proposal to renovate the existing Parish Center (former nunnery) on the subject property was previously brought before the KHPRC on October 17, 2019. Based on the Director’s Report to the KHPRC and the meeting minutes, it is evident that the project presented at the time is the same as the currently proposed project. We understand through discussions with the current Applicant, Kamehameha Schools, and the Landowner, Roman Catholic Church, that the plans were originally commissioned by the Landowner and brought before the Planning Department with the intent to obtain feedback on the proposal and initiate the entitlement process. Due to the early, conceptual level of detail in the plans, the KHPRC requested that the applicant return at a later date with more historical documentation, if any, and more detailed floor plans and elevations so that the KHPRC can make an educated and informed decision. No further action was taken on the application and the current Applicant (Kamehameha Schools), and the Landowner have been in discussions to lease and improve the space since then. 10470-01 Letter to Ms. Marisa Valenciano October 25, 2021 Page 2 Following up on the request of the KHPRC, we made inquiries with the Kaua‘i Historic Society (KHS) and the Landowner to try and obtain historical photos of the Parish Center around the time of its initial construction. No historical photos resulted from these inquiries. KHS noted they did find a Garden Island special edition on St. Catherine’s in 1958 for the dedication but it had no photos of the convent. In speaking with the former Director of St. Catherine’s Church, anecdotal evidence was provided to indicate that the Parish Center building itself still consists of original materials (CMU block wall) although the original roof and windows were replaced more recently in 1992 following damage sustained from Hurricane Iniki. Another unfortunate result of the hurricane was that much of the Church’s historic records were also lost. It should be noted that the proposed project mainly consists of interior improvements to accommodate new classrooms and support facilities. Improvements to the exterior are proposed to be similar in character to the existing condition and in consonance with surrounding buildings. Additional details are provided in the Applicant’s Use Permit and Class IV Zoning Permit Application (Refer to Section IV.A.3. “Project Description” and Exhibit D). KHPRC November 18, 2021 Meeting Based on the 2019 meeting minutes, KHPRC voted to receive the Director’s Report and conceptual plans presented at the time with the request to have the applicant come back when more detailed plans are available. Pursuant to this request, we are returning to the KHPRC with more detailed plans for the subject project. There have been no significant changes to the plans since 2019 except for minor changes to the interior layout and more details provided related to the proposed exterior and on-site improvements. Should you have any questions, please feel free to call me at (808) 946-2277 or email me at rcandilasa@wilsonokamoto.com.

Summary Kamehameha Schools (“KS” or “Applicant”) proposes to lease the existing structure on the southern portion of TMK (4) 4-6-015:058 (“Subject Property”) for use as a preschool. The Subject Property is an approximately 1.09-acre lot located in Kapa‘a, Kaua‘i, Hawai‘i that is currently owned by the Roman Catholic Church (“Landowner”). Various interior and exterior improvements, as well as onsite improvements are proposed to accommodate the new use (“Project”). The Applicant is requesting that the Planning Commission issue a Use Permit and Class IV Zoning Permit for the proposed Project pursuant to CZO requirements. KS has 29 preschools statewide that enroll over 1,600 keiki (children). Each classroom typically consists of about 20 keiki ages three and four years old, a qualified teacher, and a teaching assistant. Upon completion of the proposed Project, keiki currently attending KS’ preschool in Anahola will be relocated and the Anahola location will be closed. The purpose of the Project is to provide educational facilities in alignment with KS’ mission to fulfill Bernice Pauahi Bishop’s desire to create educational opportunities in perpetuity to improve the capability and well-being of people of Hawaiian ancestry.

Graphic & Schematic Requirements Supporting figures are attached hereto as Exhibit C. Preliminary design drawings of the proposed Project are attached hereto as Exhibit D. IV. Project Description A. Description of the proposed project and proposed uses, operations and management of the proposed use which includes, but is not limited to, proposed employee housing plan, hours of operation; 1. Project Location: The Subject Property is located in Kapa‘a on the east side of Kaua‘i. It is bound by Kawaihau Road to the north, Hauaala Road to the east, St. Catherine School to the south, and a parking lot and park/playground area to the west. Improvements are proposed to occur on approximately 0.40 acres of land situated on the southern half of the Subject Property (“Project Site”). See Figures 1 and 2 of Exhibit C. 2. Existing and Surrounding Uses: The Subject Property is entirely developed with a church and its accessory facilities. Existing structures onsite include St. Catherine Parish situated on the northern half of the property and a Parish Center situated on the southern half of the property. Parking for the facilities is located on an adjacent parcel to the west identified as TMK: (4) 4-1- 015:067. St. Catherine Parish is open to the public and provides facilities for worship and other religious activities. The Parish Center is used for multiple purposes including offices, meeting rooms, a gift shop, and storage, all of which are accessory to the primary church-related activities occurring at St. Catherine Parish. Since the usage of the Parish Center is based on need, it is not consistently occupied. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 3 The proposed Project involves improvements to the existing Parish Center, which consists of one (1) single-story, U-shaped building with the open side of the U-shape oriented to the south. The existing structure encompasses approximately 4,300 square feet (sf) of the 0.40-acre Project Site. Landscaping and a grass/gravel parking area with a driveway providing ingress and egress from Hauaala Road make up the remainder of the Project Site. Other surrounding land uses in the vicinity include St. Catherine School, single-family residences, neighborhood businesses, Kapa‘a Elementary School, and Kapa‘a High School. See Figure 1 of Exhibit C. 3. Proposed Project and Proposed Uses: The Applicant proposes to lease the existing structure at the Project Site for use as a preschool. Project improvements consist of various interior and exterior improvements to the existing structure, as well as on-site improvements needed to accommodate the proposed use. The proposed interior improvements include reconfiguring the interior layout to accommodate two (2) classrooms, toilets, offices, a meeting space, and a reception area. The existing kitchen space will remain, but the existing interior finishes, casework, and fixtures are proposed to be replaced. All existing electrical systems will be replaced with code compliant systems including updated electrical infrastructure, LED lighting, and a new fire alarm system. New plumbing systems will also be provided throughout the building. Proposed improvements to the exterior of the building include repairing the existing roof and installing new gutters, windows, and doors to replace the existing components. Repair of the roof will consist of installing new asphalt shingles similar in color and character to the existing roof. The existing glass jalousie windows will be replaced with vinyl jalousie windows and new metal and sliding glass doors will be installed. The existing plaster exterior finish is proposed to remain and will be repainted in a color scheme consistent with the existing condition and character of St. Catherine Parish. A new covered walkway will be constructed along the south wall of the existing structure to allow children and staff to move between spaces while also providing protection from the elements and shading. The walkway structure will be constructed of the same materials as the building including wood framing and asphalt shingle roofing. An exterior play yard is also proposed in this area and will consist of a new concrete slab enclosed with a 6-foot-high chain-link fence along the perimeter. Other onsite improvements include paving the existing grass/gravel lot and driveway with asphalt concrete to meet accessibility and fire access requirements. A new ADA-compliant walkway will also be constructed along the north facing side of the building to provide access from the parking area. In addition, the existing cesspool located onsite will be replaced with a new septic system and leach field. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 4 Preliminary design drawings of the proposed Project are attached hereto as Exhibit D. Construction of the proposed Project is expected to be initiated upon approval of the necessary permits and approvals with anticipated completion by 2022. 4. Operations and Management: The preschool is expected to accommodate a maximum enrollment of 40 students and will be staffed with six (6) full-time employees with an additional one (1) to two (2) staff present onsite to provide support as needed. Hours of operation for the preschool will be Monday through Friday from 7:00 am to 5:00 pm with staff expected to be onsite between 6:45 am and 5:30 pm. It is anticipated that the school will be closed on weekends and holidays. Primary access to the project site will be provided via the existing driveway for St. Catherine Parish off Kawaihau Road with secondary access provided via the existing driveway off Hauaala Road. The existing parking lot adjacent to St. Catherine Parish accessed via the driveway off Kawaihau Road will serve as parking for the preschool’s pick-up and drop-off operations. This parking lot has 33 paved parking stalls, 3 ADA-accessible stalls, 34 unpaved parking stalls (total of 70 stalls) and a turnaround area. Use of these stalls will be formalized in the terms of the lease agreement. It is anticipated that the Applicant will also have use of the existing grass/gravel parking area at the Project Site for use by staff and visitors. Access to this lot is provided via the driveway off Hauaala Road. B. Summary of Permits (i.e. Use Permit, Variance Permit, Special Permit, Class IV Zoning etc.) or Land Use Amendments requested, and the application section of the Kauaʻi County Code or regulation citing the specific standards and criteria for granting of the permit or amendment being requested; 1. County Zoning Designation: The County of Kaua‘i Comprehensive Zoning Ordinance (CZO) lists within each zoning district of the County, those uses, development, and activities, that are “generally permitted” and those which may be allowed only after obtaining a Use Permit. The Subject Property is located within both the County’s Residential (R-4) and Special Treatment-Public Facilities (ST-P) District. Special Treatment Districts may overlap any Use District, thereby creating accumulated regulations which more nearly relate to the conditions of the specific location where the development or use may occur. Allowable uses within the R-4 District consist of residential dwelling units constructed to a density of up to four (4) dwelling units per acre. Allowable uses within the ST-P District include: All public and quasi-public facilities, other than commercial, including schools, churches, cemeteries, hospitals, libraries, police and fire stations, government buildings, auditoriums, stadiums, gymnasiums, which are used by the general public or which tend to serve as gathering places for the general public; and those areas which because of their unique locations are specially suited for such public and quasi-public uses. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 5 2. Existing Use and Conformance with the CZO: The Parish Center was first built in 1952 and was historically used as a home for nuns (“nunnery”) of St. Catherine Parish. With the departure of the nuns in 2005, the nunnery was re-purposed into a Parish Center, which is an accessory use to the church much like the nunnery. Since the building was constructed in 1952 prior to the adoption of the County’s CZO in 1972, the building and its use are considered nonconforming. As stated in CZO Section 8-13.2(a): A non-conforming use of land, buildings, or other structures may continue to the extent that the use existed on September 1, 1972 or any amendment hereto, as provided in this Section 8-13.2 […] Moreover, CZO Section 8-13.1(b) states nonconforming structures may be “repaired, maintained, or altered in any manner which does not increase nonconformity.” Based on the foregoing reasons, and because the existing use presents no substantial danger to public health or safety, the existing use and structures are in compliance with prevailing land use regulations. 3. Proposed Use and Conformance with the CZO: Under the proposed Project, the Applicant will convert the Parish Center into a preschool that will provide educational programs for keiki between the ages of three and four. Pursuant to CZO Section 8-13.1(b), “[a]ny nonconforming structure, except as otherwise regulated, may be enlarged or expanded provided that any enlargement or addition shall conform to the regulations for the district in which it is located.” Schools are a permitted use in the R-4/ST-P District with a Use Permit consistent with CZO Sections 8-2.4(f)(13) and 8-11.4(a). 4. Permits Requested and Required: The Applicant is requesting that the Planning Commission issue a Use Permit pursuant to CZO Section 8-3.2 for the proposed Project. This permit application is intended to fulfill the requirements for project review in accordance with CZO Section 8-3.2. Likewise, the proposed Project requires issuance of a Class IV Zoning Permit as a condition of the Use Permit approval pursuant to CZO Section 8-8.4(4). Therefore, this permit application submittal also fulfills requirements for project review pursuant to CZO Section 8-3.1(f) pertaining to Class IV Zoning Permits. 5. Use Permit and Zoning Permit Considerations: The primary purpose of the Use Permit process is to assure that a particular activity or use of land can be integrated into and be compatible with its immediate surroundings. Section 8-3.2(e)(1) of the CZO specifies a Use Permit may be granted only if the Planning Commission finds that the use meets the following criteria: a. the use must be a compatible use; The Project Site is located in a residential neighborhood in the vicinity of several other schools and neighborhood businesses. The proposed use of the Project Site as a preschool will satisfy an essential community need by providing educational programs St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 6 and activities that support the growth and development of children in the region. It can be reasonably expected that with education these children will go on to make meaningful contributions to society later in life. The placement of schools within residential neighborhoods and/or in a centralized location further enhances convenience for residents and allows residents to take advantage of available educational opportunities, as evidenced by the location of other schools in the area such as St. Catherine School (Grades K to 5), Kapa‘a Elementary School (Grades K to 6), and Kapa‘a High School (Grades 9 to 12). For the reasons mentioned, the proposed use is compatible with the uses in its immediate surroundings and would not be detrimental to the health, safety, peace, morals, comfort, and the general welfare of persons residing and working in the neighborhood. b. the use must not be detrimental to persons or property in the area; Operation of the preschool will be within normal working hours. The proposed Project improvements will be in conformance with the development standards applicable to the R-4/ST-P District in the County’s CZO and as conditioned by the Planning Commission with approval of the subject Use Permit. Construction and operation of the Project is not anticipated to be detrimental or injurious to property and improvements in the neighborhood or to the general welfare of the community. c. the use must not cause substantial environmental consequences; and Construction of the proposed project will not result in any substantial harmful environmental consequences. Project improvements are the minimum necessary to convert the use of the existing structure to a preschool and to ensure the structure is compliant with all prevailing building code requirements and safety regulations. Mitigative measures—such as standard best management practices (BMPs) for construction and adherence to applicable federal, State, and County rules and regulations—will be incorporated into the design to ensure there will be no substantial harmful environmental consequences on the land or on other lands or waters. Following construction, the proposed use is not anticipated to result in any significant environmental consequences beyond what would have previously existed under the former use of the Project Site as a nunnery. A more detailed discussion on potential environmental impacts of the Project by topic is provided below. Climate and Climate Change: The climate in the project area is characterized as semi- tropical with two seasons: wet and dry. During May through September, it is generally warm and relatively dry, with predominantly northeast trade winds. October through April is associated with lower temperatures and higher rainfall, and less prevalent trade winds. Long term data collected at the Līhuʻe Airport indicated that the northeast wind direction prevails throughout the year with a mean annual wind speed of 20 miles per hour. The average daytime maximum temperature ranges from about 78 degrees in the winter to 85 degrees in the summer. Average annual rainfall is about 43 inches. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 7 Construction and operation of the project is anticipated to result in the release of greenhouse gas emissions. However, these emissions are anticipated to be minimal since the proposed Project involves renovation of an existing structure and trips generated by the project are likely to occur without construction of the Project. In addition, the Project design will incorporate energy efficient fixtures and will aim to utilize passive cooling to avoid energy demands associated with air conditioning. Topography: No significant changes in topography are proposed. The Project Site sits about 140 feet above mean sea level; see Figure 3 in Exhibit C. It is generally flat and was graded for construction of the existing building onsite. Project improvements involve renovating the existing structure, which would not require any mass grading. Although some grading is proposed to construct the new walkways and play yard area, topography of the site is expected to remain similar to existing conditions. Soils: According to the U.S. Department of Agriculture, Natural Resources Conservation Services Web Soil Survey, soils underlying the Project Site are classified as Lihue silty clay (LhB); see Figure 4 in Exhibit C. The Lihue series consists of deep, well drained soils that formed in material weathered from basic igneous rock and influences by tropospheric dust. Lihue soils are on uplands and have slopes of 0 to 40 percent. Surface Water: There are currently no natural surface water resources, such as streams, rivers, lakes, wetlands, reservoirs, and creeks in the vicinity of the Project Site. No impacts to surface waters are anticipated with the proposed Project. Coastal Waters: The Project Site is located inland and away from the coast. Additional runoff generated by the proposed project will be retained on-site. No impacts to coastal waters are anticipated with the proposed Project. Drainage: A portion of the project site is already developed with impervious surfaces. Increases in runoff will be minimal and any additional runoff generated by the proposed project will be retained on-site. Flood Hazard: The Project Site is located within FEMA Flood Zone X, areas determined to be outside the 0.2% annual chance floodplain; see Figure 5 in Exhibit C. No impacts to the flood zone and to downstream properties are anticipated with the proposed Project. Sea Level Rise: The Project Site is not located in an area vulnerable to sea level rise. Flora: The project site is entirely developed with vegetation at the site consisting primarily of grass, a plumeria tree, and ornamental plants commonly used for landscaping. No trees are proposed to be removed with the proposed project and no St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 8 habitats of state or federally listed, threatened or endangered species will be affected by construction and operation of the proposed Project. Fauna: The Subject Property is entirely developed and does not serve as a habitat for any state or federally listed, threatened or endangered species. To minimize any potential harm to seabirds that may overfly the project site, the Applicant will utilize downward facing lighting to the maximum extent possible to avoid attracting these birds; and/or to reduce any possible attractive lighting to the extent reasonably possible during the critical two-week period before and after the new moon each October. No significant impacts on fauna within the project site are anticipated from either the construction or operation of the proposed Project. Noise: Ambient noise in the vicinity of the Project site is predominantly attributed to vehicular operations on the surrounding roadways. Temporary increases in noise levels associated with construction related activity for the proposed project are not anticipated to substantially affect nearby uses due to the temporary and intermittent nature of construction activities. All equipment used during construction will be properly muffled, housed and maintained. Any potential impacts on noise receptors in the area will be mitigated with the implementation of BMPs and by complying with the applicable provisions of State DOH Administrative Rules, Title 11, Chapter 46, “Community Noise Control.” Air Quality: Air quality within the project site is generally considered to be good due to sparse development surrounding the subject property and the absence of point-source pollutant generators in the vicinity. Temporary increases in fugitive dust are anticipated to have negligible impacts on air quality in the project vicinity as the emissions would be relatively small and readily dissipated. Any potential air quality impacts will be mitigated by implementing BMPs to control fugitive dust and by complying with the applicable provisions of State DOH Administrative Rules, Tile 11, Chapter 60 “Air Pollution Control.” No long-term impacts to air quality are anticipated with the proposed Project. Archaeological/Historic Resources: The existing structure at the Project Site was originally constructed in 1952 making it a historic property as it is over 50 years old in age. The building itself is made up of original materials consisting of CMU block walls finished on the exterior with plaster. The asphalt shingle roof and glass jalousie windows were more recently replaced in 1992 following damage sustained during Hurricane Iniki. The existing building is not listed on the State or National Register of Historic Places. The National Park Service’s guidance document titled How to Apply the National Register Criteria for Evaluation states that ordinarily properties owned by religious institutions or used for religious purposes are not considered eligible for the National Register. However, such properties will qualify for eligibility if they fall within the following categories: St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 9 • A religious property deriving primary significance from architectural or artistic distinction or historical importance; or • A building or structure removed from its original location but which is significant primarily for architectural value, or which is the surviving structure most importantly associated with a historic person or event; or • A birthplace or grave of a historical figure of outstanding importance if there is no appropriate site or building directly associated with his or her productive life; or • A cemetery which derives its primary significance from graves of persons of transcendent importance, from age, from distinctive design features, or from association with historic events; or • A reconstructed building when accurately executed in a suitable environment and presented in a dignified manner as part of a restoration master plan, and when no other building or structure with the same association has survived; or • A property primarily commemorative in intent if design, age, tradition, symbolic value has invested it with its own exceptional significance; or • A property achieving significance within the past 50 years if it is of exceptional importance. This historic property does not fall into any of the foregoing categories and is therefore not considered eligible for listing. It is not associated with any significant event or person of interest and the building architecture is not unique to the period it was constructed, nor does it appear to have any historic significance. A Reconnaissance Level Survey prepared by Ushijima Architects is attached hereto as Exhibit E. There are no other known historic properties within the Project Site. Some ground disturbance is proposed for construction of the new walkways and play yard area, as well as for replacement of the cesspool with a septic tank and leach field. Should there be any inadvertent discoveries, all work in the area of the archaeological/historical findings shall immediately cease and the Applicant shall contact the State Department of Land and Natural Resources, Historic Preservation Division and the Planning Department to determine mitigation measures. Cultural Resources: The proposed Project involves renovation of an existing development and will have no impact on any known traditional or customary practices of native Hawaiian for the following reasons: • There are no known traditional or customary practices of native Hawaiians that are presently occurring within the Project Site. • There are no special gathering practices taking place within any portion of the Project Site. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 10 • The Project will not detrimentally affect access to any streams; access to the shoreline or other adjacent shoreline areas; or gathering along any streams, the shoreline or in the ocean. • There are no known religious practices taking place within the Project Site. • There are no known pre-contact cultural or historic sites or resources located within the Project Site. • There are no known burials within the Petition Area. By letter dated October 20, 2021, Mr. Sean Chun of Wailua, Kaua‘i, a known cultural practitioner and kumu of various Hawaiian arts, noted that there are no cultural sites or relevance that would inhibit Hawaiian cultural practices. A copy of the letter is provided in Exhibit F. A discussion on potential impacts related to visual resources, public services and facilities, traffic, parking, water, wastewater, and solid waste is provided in Sections IV.F. to IV.I. of this application. d. the use must not be inconsistent with the intent of the CZO and General Plan. The proposed Project will be designed and developed in conformance with the development standards applicable to the R-4/ST-P District as established in the CZO and as conditioned by the Planning Commission with approval of the subject Use Permit. The proposed use is an allowable use with issuance of a Use Permit, which is the subject of this permit application. Discussion of the project’s consistency with the General Plan is discussed in the following sections. C. Policies and Objectives of the General Plan; the provisions of the Community Development Plan applicable to the application (including design standards and application requirements); the provisions of the applicable zoning district; and an analysis of the extent to which the application, if granted, conforms to these provisions of the applicable district; and an analysis of the extent to which the application, if granted, conforms to these policies, objectives and provisions; 1. County of Kaua‘i General Plan (2018): The General Plan Vision & Goals for Kaua‘i are series of statements that express the community’s values and desired outcomes in the year 2035. The proposed Project is consistent with the following applicable Vision & Goals of the Kaua‘i General Plan: Goal 4: An Equitable Place, with Opportunity for All The proposed use of the Project Site as a preschool will contribute to the goal of creating an equitable place, with opportunity for all by providing opportunities for and access to early education. Location of the facility in the context of a residential neighborhood will enhance convenience for residents in the community and improve quality of life. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 11 Policies and actions of the Kaua‘i General Plan flow from the Vision & Goals. There are nineteen policies to address the issues most important to Kaua‘i residents in the face of existing issues and future growth. These policies articulate the County’s path forward toward meeting the community’s vision and goals of sustainability, unique character, resilience and equity. The proposed Project is consistent with the following applicable policies of the Kaua‘i General Plan: Policy 1: Manage Growth to Preserve Rural Character This policy aims to preserve Kaua‘i’s rural character by limiting the supply of developable land to an amount adequate for future needs, prohibit development not adjacent to towns, and ensure new development occurs inside growth boundaries and is compact and walkable. The proposed Project involves renovation of an existing structure for use as a preschool, which would not require the development of vacant land and open space. Additionally, the Project Site is located within an established neighborhood in Kapa‘a adjacent to residences and other compatible uses. Policy 4: Design Healthy and Complete Neighborhoods This policy aims to ensure new and existing neighborhoods have safe roads, functional parks, as well as access to jobs, commerce, transit, and public services. As mentioned previously, the Project Site is located within an established neighborhood in Kapa‘a adjacent to residences and other compatible uses. Location of the facility in the context of a residential neighborhood will enhance convenience for residents in the community and improve quality of life. In addition, the County of Kaua‘i Department of Public Works (DPW) is proposing several Complete Streets and Safe Routes to School improvements in the vicinity. Design of the project will provide appropriate connection to these facilities as appropriate and as coordinated through consultation with DPW. Policy 17: Nurture Our Keiki This policy aims to value youth as Kaua‘i’s most treasured resource. It also aims to provide youth with safe communities, great schools and facilities, and financially sustainable jobs, housing, and transportation opportunities so they are able to seek livelihoods on Kaua‘i. The proposed Project involves renovation of an existing structure for use as a preschool that will provide early education opportunities for keiki between the ages of three and 4. It can be reasonably expected that with education these children will go on to make meaningful contributions to society later in life. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 12 Policy 19: Communicate with Aloha This policy notes that Kaua‘i’s residents care about planning and decision-making. Therefore, the government must share information, encourage input, improve public processes, and be responsive. The scheduling of this Application before the Planning Commission will allow the public to participate in the planning and decision-making process for the proposed Project. Future Land Use and Community Planning As shown in Figure 6 of Exhibit C, the Project Site is designated within Residential Community. This designation indicates existing areas that are primarily residential with few to no other uses. The Project Site is also designated within the community planning district of East Kaua‘i. One of the preliminary vision and priorities for East Kaua‘i residents include the ability of residents to enjoy a high quality of life in a rural setting. The proposed use of the Project Site as a preschool will satisfy an essential community need and allow residents to have convenient access to early education opportunities. Along with future land use and community planning, there are ten sectors that represent important areas to be addressed when planning Kaua‘i’s growth and development. The proposed Project is consistent with the following applicable sectors and their actions: Sector X. Opportunity & Health For All One of the identified issues in this sector is access to quality education and training. As outlined in the Kaua‘i General Plan, the objective for this issue is to support educational programs that foster cultural knowledge, employability, and civic participation of local residents. Some of the implementing actions associated with this objective include increasing access to early education and care and supporting the language, culture, and knowledge of Kaua‘i. The preschool will accommodate the same number of students as their location in Anahola. The Hawaiian cultural values of aloha, mālama, and kuleana are an integral part of the KS preschool program experience. KS strives to nurture these values while continuing to provide a learning environment that is safe, educational, culturally-grounded, enjoyable and enriching. By providing a preschool facility, the Project fulfills the purpose of the proposed Project to provide educational facilities in alignment with KS’ mission. Approval of the Use Permit will not only allow for the use and development of these facilities, it will also directly implement the permitting and code changes outlined in the Kaua‘i General Plan, specifically the following: Support the use, expansion, and development of family childcare homes, preschools, parent/child kindergarten readiness programs, and charter schools. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 13 2. Kapa‘a-Wailua Development Plan (1973): The adopted version of the Kapa‘a-Wailua Development Plan dates back to 1973. Although efforts were made to update the plan in more recent years, that plan was never officially adopted. Therefore, the goals and objectives of the 1973 Kapa‘a-Wailua Development Plan are still active even though they may not necessarily reflect the current goals and objectives of the residents in the region. It is understood that the more recent, comprehensive community planning process undertaken as part of the development of the Kaua‘i General Plan (2018) more accurately reflects the vision for the East Kaua‘i Community. Therefore, reference should be made to the “Future Land Use and Community Planning” discussion provided in Section IV.C.1. of this application. Nevertheless, the following is a discussion on the Project’s compliance with the applicable goals and objectives of the 1973 Kapa‘a-Wailua Development Plan. Objective II. Education & Recreation The educational objective states that “[t]he educational program should be separated into three levels—kindergarten to sixth, seventh to ninth, and tenth to twelfth grades— corresponding to the three “social” levels of attitude.” Although preschool is not specifically mentioned, it is acknowledged that early education at the preschool level is a part of the broad spectrum of educational pursuits, thereby making the proposed Project consistent with the educational objectives of the Kapa‘a-Wailua Development Plan. 3. County of Kauaʻi Comprehensive Zoning Ordinance: Compliance with the use standards of the CZO are the subject of this application and are discussed throughout. Pursuant to CZO Section 8-4.9 pertaining to development of other uses in a residential district: All permitted uses, all uses requiring a use permit, and all uses allowed by variance other than residential: (a) Shall conform to development standards established for the district in which they are normally permitted provided that: (1) the minimum distance from property lines shall be the same as that required for Single Family Detached Dwellings; and (2) the maximum building heights shall be the same as that required for Single Family Detached Dwellings; or (b) Shall conform to the requirements and conditions imposed by the Planning Commission in granting the use permit or variance permit. A Use Permit is required for schools in any district. Therefore, the Project will be designed and constructed in conformance with the requirements of the CZO and the conditions imposed by the Planning Commission in granting the subject Use Permit. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 14 D. Detailed land use history of the parcel, which includes but is not limited to, former and existing State and County land use designations, violations and uses; The Parish Center on the Subject Property was first built in 1952 and was historically used as a nunnery for the nuns of the St. Catherine Parish. Around 2005, the nunnery was re-purposed as a Parish Center, which is accessory to the primary use of the subject property as a church. The existing State land use designation of the site is Urban and the existing County land use designation of the site is R-4/ST-P. Since the building was constructed in 1952 prior to the adoption of the County’s CZO in 1972, the building and use are considered nonconforming. In 1992, repairs to the existing roof and windows were made following Hurricane Iniki. No major modifications to the structure have been undertaken which would have increased its nonconformity and the use presents no substantial danger to public health or safety. Additionally, there are no known land use violations related to the subject property and its existing uses. E. Status reports of all Zoning Amendment ordinance conditions, existing Land Use Permit conditions, and Subdivision Application conditions pertaining to the project site; There are no known Zoning Amendment ordinance conditions, existing Land Use Permit conditions, and Subdivision Application conditions pertaining to the project site. There are currently no known violations related to the subject property and its existing uses. F. Analysis of the secondary impacts of the proposed use on the surrounding area, which includes but is not limited to, increases in property value, population, housing, community services and facility needs, secondary jobs and employment generated, and compatibility with the surrounding uses; The Project Site is located in an established neighborhood with little to no vacant land available for development. The proposed use fulfills an essential community need and is not likely to induce population growth that would have secondary impacts on the surrounding area, such as an increase in demand for housing or community services and facilities. The Project is also not likely to significantly increase property values as there are already several educational facilities in the area. It is anticipated that converting the use from the Parish Center, which is not consistently occupied, to a preschool will generate additional traffic in the area. A Traffic Impact Report for the St. Catherine Preschool was prepared in July 2021 to assess the traffic impacts resulting from the Project. A copy of the report is provided in Exhibit G. Based on the assessment, traffic operations along Kawaihau Road are generally expected to remain similar to without project conditions. The following recommendations were made for consideration to incorporate into the Project design: St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 15 1. Verify sufficient sight distance for motorists to safely enter and exit all project driveways including the driveways off Kawaihau Road and Hauaala Road. 2. Verify adequate on-site loading and off-loading service areas and prohibit off-site loading operations. 3. Verify adequate turn-around area for service, delivery, and refuse collection vehicles to maneuver on the project site to avoid vehicle-reversing maneuvers onto public roadways. 4. Verify sufficient turning radii at all project driveways to avoid vehicle encroachments to oncoming traffic lanes. 5. Ensure that the existing grass/gravel lot off Hauaala Road that is expected to be used as the preschool’s staff parking lot is made accessible in conformance with the Americans with Disabilities Act (ADA) requirements. 6. Ensure that pedestrian connections to and from the existing parking area off Kawaihau Road are accessible in conformance with ADA requirements. This lot is expected to be designated as the parking lot for pick-up/drop-off for the preschool. 7. Consider providing signage near the project driveway off Hauaala Road to inform students and parents of the preschool where the designated parking for pick-up/drop off is located. In addition, provide information to indicate that the parking lot off Hauaala Road is for staff parking only. 8. Coordinate with the County of Kauai to ensure that appropriate modifications for the project driveways are incorporated into their complete streets project and that sufficient sight distances and turning radii are maintained for vehicles entering/exiting the project site. DPW is expected to construct a five-legged peanut-shaped roundabout at the intersections of Kawaihau Road with Hauaala Road and Mailihuna Road. These improvements are anticipated to facilitate traffic flow through the intersection and accommodate site-generated trips. Also, with adequate parking available through the lease agreement with the Landowner, no additional parking is anticipated to be required for this Project. Secondary impacts on visual resources are also not anticipated with the proposed Project as the project will not significantly increase the height of the existing building, nor will it significantly expand the existing development footprint. In addition, all materials and finishes used will be in consonance with the character of the surrounding uses. G. Water source, supply and distribution system analysis, which includes but is not limited to, methods of irrigation that exists on the parcel and proposed for the application, location and use of groundwater and non-potable water sources; The proposed project will install a new plumbing system within the building and will use the existing water service provided by the County of Kauaʻi Department of Water Supply (DWS). The Applicant will coordinate with DWS regarding the availability of water and any improvements needed to support the proposed use. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 16 H. Sewage Disposal Analysis – A description of a proposed method of sewage disposal; Wastewater generated by the subject property is collected by an existing cesspool located on- site. Proposed project improvements will include installation of a new septic tank and leach field sized and designed for the collection and treatment of wastewater generated by the proposed use. Closure of the existing cesspool and construction of the new wastewater system will be constructed in compliance with applicable federal, State, and County rules and regulations pertaining to wastewater systems. I. Solid Waste Disposal Analysis – A description of a proposed method of solid waste disposal, including methods for recycling, reclamation and waste stream diversion; and During construction, the contractor will be responsible for the disposal of all construction and demolition waste. Following construction, solid waste will continue to be collected by a private contractor. The Applicant will incorporate recycling, reclamation and waste stream diversion practices in day-to-day activities at the preschool to the maximum extent practicable. Additional solid waste that may be generated by the construction and operation of the proposed project is not anticipated to place significant demand on existing solid waste facilities and will have not have a significant impact on future capacity. J. Description of environmentally sensitive areas, habitat and botanical features, which includes but is not limited to, wetlands, streams, rock outcroppings, endangered plants and animals, and exceptional trees. 1. Surface Water There are currently no natural surface water resources, such as streams, rivers, lakes, wetlands, reservoirs, and creeks in the vicinity of the project site. Additional runoff generated by the proposed project will be retained on-site. No impacts to surface waters are anticipated with the proposed Project. 2. Coastal Waters The proposed project is located inland and away from coastal waters. Additional runoff generated by the proposed project will be retained on-site. No impacts to coastal waters are anticipated with the proposed Project. 3. Flora The project site is entirely developed with vegetation at the site consisting primarily of grass, a plumeria tree, and ornamental plants commonly used for landscaping. The proposed Project involves renovation of an existing structure that will be slightly expanded to accommodate new walkways and a new play area. No trees are proposed to be removed with the proposed project. Furthermore, no habitats of state or federally listed, threatened or endangered species will be affected by construction and operation of the proposed Project. St. Catherine Preschool Use Permit and Class IV Zoning Permit Application 17 4. Fauna The Subject Property is entirely developed and does not serve as a habitat for any state or federally listed, threatened or endangered species. To minimize any potential harm to seabirds that may overfly the project site, the Applicant will utilize downward facing lighting to the maximum extent possible to avoid attracting these birds; and/or to reduce any possible attractive lighting to the extent reasonably possible during the critical two-week period before and after the new moon each October. No significant impacts on fauna within the project site are anticipated from either the construction or operation of the proposed Project.

INTRODUCTION A. Purpose of Study The purpose of this study is to identify and assess the traffic impacts resulting from the renovation of an existing building within the St. Catherine Parish in Kapaa, Kauai. The building previously served as a nunnery and will be converted into a preschool. B. Scope of Study This report presents the findings and conclusions of the traffic study, the scope of which includes: 1. Description of the proposed project. 2. Evaluation of existing roadway and traffic operations in the vicinity. 3. Analysis of future roadway and traffic conditions without the proposed project. 4. Analysis and development of trip generation characteristics for the proposed project. 5. Superimposing site-generated traffic over future traffic conditions. 6. The identification and analysis of traffic impacts resulting from the proposed project. 7. Recommendations of improvements, if appropriate, that would mitigate the traffic impacts resulting from the proposed project. II. PROJECT DESCRIPTION A. Location The existing St. Catherine Parish is located adjacent to Kawaihau Road in Kapaa on the island of Kauai (see Figure 1). The parish is bounded by Kawaihau Road to the north, Hauaala Road to the east, Moa Road to the west, and school and residential uses to the south. The building that will house the proposed preschool is located near the center of the site south of the existing St. Catherine Church. Access to the proposed project is expected to be provided via driveways off Kawaihau Road and Hauaala Road. B. Project Characteristics The proposed project entails the conversion of an existing building which previously served a nunnery within the St. Catherine Parish. The building will be renovated to include two classrooms and other support facilities for a preschool that is FIGURE 1LOCATION MAP AND VICINITY MAP ST. CATHERINE PRESCHOOL 0 500 2000 Feet1000 Project Site Island of Kauai Project Site Traffic Impact Report for St. Catherine Preschool Page 3 expected to accommodate a maximum of 40 students. Primary access to the project site will be provided via an existing driveway for the St. Catherine Parish off Kawaihau Road with secondary access provided via an existing driveway off Hauaala Road. Parking for the preschool’s pick-up and drop-off is expected to be provided via an existing parking lot for the St. Catherine Parish accessed via the driveway off Kawaihau Road. Parking for staff will be provided via an existing grass/gravel lot near the north edge of the preschool building with access to the lot provided via the driveway off Hauaala Road. The project is expected to be completed by Year 2022. See Figure 2 for the proposed site plan. III. BASELINE TRAFFIC CONDITIONS A. Area Roadway System The St. Catherine Parish is located adjacent to Kawaihau Road, a two-way, two-lane County of Kauai roadway generally oriented in the east-west direction serving as a main thoroughfare through Kapaa. Northeast of the project site, Kawaihau Road intersects Hauaala Road. At this unsignalized intersection, the eastbound approach of Kawaihau Road includes one lane that serves all traffic movements. The westbound approach includes one lane that serves through and right-turn movements with a center lane that facilitates left-turn movements. Hauaala Road is a two-way, two lane County of Kauai roadway generally oriented in the north-south direction. At the intersection with Kawaihau Road, the northbound and southbound approaches of Hauaala Road include a stop-controlled lane that serves all traffic movements. Less than 150 feet east of the intersection with Hauaala Road, Kawaihau Road intersects Mailihuna Road. At this unsignalized T-intersection, the eastbound approach on Kawaihau Road includes a center lane that facilitates left-turn movements and a shared through and right-turn lane. The westbound approach has one lane that serves all traffic movements. Mailihuna Road is a two-lane, two-way County of Kauai roadway that starts as an east-west roadway at the intersection with Kuhio Highway (Route 56) but transitions to a north-south roadway at the intersection with Kawaihau Road. The southbound approach of Mailihuna Road includes one stop-controlled lane that serves all traffic movements. PROJECT SITE PLAN FIGURE 2 ST. CATHERINE PRESCHOOL K A W A I H A U R O A D Traffic Impact Report for St. Catherine Preschool Page 5 B. Multimodal Facilities Multimodal facilities are currently limited in the vicinity of the project site. Pedestrian facilities are limited to roadway shoulders along Kawaihau Road and crosswalks to facilitate pedestrian crossings while there are no existing bicycle facilities around the project site. In addition, transit services in the vicinity are provided by “The Kaua’i Bus” (operated by the County of Kauai) with only one bus stop located within a quarter mile of St. Catherine Parish along Kawaihau Road adjacent to Kapaa High School. C. Traffic Volumes and Conditions 1. General a. Baseline Traffic Data The traffic data used for the purpose of analysis is based on manual turning movement counts collected in Year 2017 and included in Appendix A. The manual turning movement count survey was conducted during the morning peak hours between 6:00 AM and 9:00 AM and during the afternoon peak hours between 2:00 PM and 5:00 PM at the following intersections:  Kawaihau Road and Hauaala Road  Kawaihau Road and Mailihuna Road The traffic data from Year 2017 represents the most recently available traffic data in the vicinity of the project. More recent traffic data could not be collected at this time due to the ongoing COVID-19 pandemic that has resulted in significantly decreased traffic volumes and shifted travel patterns. The State of Hawaii Department of Transportation (HDOT) Highways Division has been tracking traffic volumes along the major regional roadways including those in Kauai. The HDOT traffic data indicates that in general, traffic volumes on the island of Kauai are still slightly below pre-COVID volumes. As such, for the purpose of this report, traffic volumes based on collected in Year 2017 were assumed to represent Year 2021 baseline conditions. It should be noted that an assessment of historical traffic data along the Traffic Impact Report for St. Catherine Preschool Page 6 roadways in the vicinity of the project indicates that traffic volumes in the vicinity were relatively stable pre-COVID. b. Capacity Analysis Methodology The highway capacity analysis performed in this study is based upon procedures presented in the “Highway Capacity Manual”, Transportation Research Board, 2010, and the “Synchro” software, developed by Trafficware. The analysis is based on the concept of Level of Service (LOS) to identify the traffic impacts associated with traffic demands during the peak periods of traffic. LOS is a quantitative and qualitative assessment of traffic operations. Levels of Service are defined by LOS “A” through “F”; LOS “A” representing ideal or free-flow traffic operating conditions and LOS “F” unacceptable or potentially congested traffic operating conditions. “Volume-to-Capacity” (v/c) ratio is another measure indicating the relative traffic demand to the road carrying capacity. A v/c ratio of one (1.00) indicates that the roadway is operating at or near capacity. A v/c ratio of greater than 1.00 indicates that the traffic demand exceeds the road’s carrying capacity. The LOS definitions are included in Appendix B. 2. Baseline Peak Hour Traffic a. General Figures 3 and 4 show the baseline lane uses and peak hour traffic volumes. The AM peak hour of traffic generally occurs between 7:00 AM and 8:00 AM. The PM peak hour of traffic generally occurs between the hours of 2:15 PM and 3:15 PM. The analysis is based on these peak hour time periods for each intersection to identify the traffic impacts resulting from the proposed project. LOS calculations are included in Appendix C. b.

Trip Generation Methodology The trip generation methodology used in this study is based upon generally accepted techniques developed by the Institute of Transportation Engineers (ITE) and published in “Trip Generation, 10th Edition,” 2017. The ITE trip generation rates are developed empirically by correlating vehicle trip generation data with various land use characteristics such as the number of vehicle trips generated per number of students. Table 1 summarizes the trip generation characteristics related to the proposed project applied to the AM and PM peak hours of traffic. Table 1: Peak Hour Trip Generation DAY CARE CENTER (PRESCHOOL) INDEPENDENT VARIABLE: Number of students = 40 PROJECTED TRIP ENDS AM PEAK ENTER EXIT TOTAL 17 14 31 PM PEAK ENTER EXIT TOTAL 15 17 32 Traffic Impact Report for St. Catherine Preschool Page 11 2. Trip Distribution Figure 5 shows the distribution of site-generated traffic during the AM and PM peak periods. Primary access to the project site will be provided via an existing driveway off Kawaihau Road with secondary access to be provided via an existing driveway off Hauaala Road. The driveway off Kawaihau Road is expected to provide access to parking for the preschool’s parking for pick-up/drop-off while the driveway off Hauaala Road is expected to serve staff parking. It should be noted that trips associated with the preschool staff are expected to access the project site prior to the peak hour in the morning and depart after the end of the school day. As such, for the purpose of analysis, all site-generated trips were distributed to the project’s primary driveway off Kawaihau Road. The directional distribution of all additional site-generated vehicles was based upon the relative distribution of traffic between the surrounding roadways. As such, 35% of trips were assumed to be traveling to/from the west via Kawaihau Road while 25% while trips to the east were split between Kawaihau Road and Mailihuna Road with 25% assumed to travel to/from Kawaihau Road and 25% of trips to travel to/from the project site via Mailihuna Road. 15% of trips were assumed to be traveling to/from the south via Hauaala Road. The distribution of all site- generated vehicles at the study intersections was based upon their assumed origin/destination and the relative convenience of available routes. B. Through Traffic Forecasting Methodology The travel forecast is based upon historical traffic count data obtained from the State DOT, Highways Division at survey stations in the vicinity of the project site. The historical data indicates relatively stable traffic volumes in the project vicinity. As such, an annual traffic growth rate of approximately 1.0% was conservatively assumed in the vicinity. Using 2021 as the Base Year, a growth rate factor of 1.01 was applied to the existing through traffic demands along the project roadways to achieve the projected Year 2022 traffic demands. C. Other Considerations A roundabout is planned to be installed at the intersection of Kawaihau Road with Mailihuna Road and Hauaala Road by the County of Kauai. Currently, there are DISTRIBUTION OF SITE-GENERATED VEHICLES WITH PROJECT FIGURE 5 ST. CATHERINE PRESCHOOL LEGEND Study Intersection XX/XX Peak Hour Volume (AM/PM)3/24/4 4/4 2/3 4/4 Traffic Impact Report for St. Catherine Preschool Page 13 two separate intersections along this stretch of Kawaihau Road with the approaches from the minor roadways stop-controlled. The proposed Kawaihau–Hauaala– Mailihuna Complete Streets project will convert these intersections into a five-legged peanut-shaped roundabout. In conjunction with this project, new sidewalks will be installed through the roundabout and along a portion of the connecting roadways including Hauaala Road adjacent to St. Catherine’s Parish. In addition, new curb ramps and modified crosswalks will be provided to facilitate pedestrian circulation in the vicinity. The proposed project is expected to be completed by the Year 2022 and as such, is incorporated into projected without project conditions. Plans for the Complete Streets improvements at the intersection of Kawaihau Road with Mailihuna Road and Hauaala Road are included in Appendix D. D. Total Traffic Volumes Without Project The baseline levels of service are shown in Table 2 while the projected Year 2022 AM and PM peak period traffic volumes and operating conditions without the completion of the proposed project is shown in Figure 6 and summarized in Table 3. The analysis incorporates ambient growth in traffic, as well as the completion of the roundabout construction at the intersections of Kawaihau Road with Mailihuna Road and Hauaala Road. LOS calculations are included in Appendix E.

The conversion of the two closely spaced intersections with Hauaala Road and Mailihuna Road into a five-legged peanut-shaped roundabout intersection is expected to facilitate traffic flow through the intersection and improve the levels of service for all approaches. The eastbound approach of Kawaihau Road is expected to operate at LOS “B” and LOS “A” during the AM and PM peak periods, respectively, while the westbound approach is expected to operate at LOS “A” during both peak periods. At the Hauaala Road approaches of the intersection, traffic operations are expected to operate at LOS “A” during both peak periods. Similarly, the Mailihuna Road approach of the intersection is also expected to operate at LOS “A” during both peak periods. E. Total Traffic Volumes With Project Figure 7 shows the projected Year 2022 cumulative AM and PM peak hour traffic conditions resulting from the proposed project. The cumulative volumes consist of site-generated traffic with the proposed preschool superimposed over Year 2022 projected traffic demands. The traffic impacts resulting from the proposed project are addressed in the following section. V. TRAFFIC IMPACT ANALYSIS The projected Year 2022 cumulative AM and PM peak hour traffic conditions resulting from the proposed project are summarized in Table 4. The projected Year 2022 (Without Project) operating conditions are provided for comparison purposes. LOS calculations are included in Appendix F.

As previously discussed, the conversion of the two closely spaced intersections with Hauaala Road and Mailihuna Road into a five-legged peanut roundabout intersection is expected to facilitate traffic flow through the intersection and accommodate site-generated trips. The eastbound and westbound approaches of Kawaihau Road are expected to continue operating at LOS “B” or better and LOS “A” during the AM and PM peak periods, respectively, whereas the northbound and southbound approaches of Hauaala Road are both expected to continue operating at LOS “A” during both peak periods. The Mailihuna Road approach of the intersection is also expected to remain similar to without project conditions. VI. RECOMMENDATIONS Based on the analysis of the traffic data, the following are the recommendations of this study to be incorporated in the project design. 1. Verify sufficient sight distance for motorists to safely enter and exit all project driveways including the driveways off Kawaihau Road and Hauaala Road. 2. Verify adequate on-site loading and off-loading service areas and prohibit off-site loading operations. 3. Verify adequate turn-around area for service, delivery, and refuse collection vehicles to maneuver on the project site to avoid vehicle-reversing maneuvers onto public roadways. 4. Verify sufficient turning radii at all project driveways to avoid vehicle encroachments to oncoming traffic lanes. Traffic Impact Report for St. Catherine Preschool Page 18 5. Ensure that the existing grass/gravel lot off Hauaala Road that is expected to be used as the preschool’s staff parking lot is made accessible in conformance with the Americans with Disabilities Act (ADA) requirements. 6. Ensure that pedestrian connections to and from the existing parking area off Kawaihau Road are accessible in conformance with ADA requirements. This lot is expected to be designated as the parking lot for pick-up/drop-off for the preschool. 7. Consider providing signage near the project driveway off Hauaala Road to inform students and parents of the preschool where the designated parking for pick-up/drop off is located. In addition, provide information to indicate that the parking lot off Hauaala Road is for staff parking only. 8. Coordinate with the County of Kauai to ensure that appropriate modifications for the project driveways are incorporated into their complete streets project and that sufficient sight distances and turning radii are maintained for vehicles entering/exiting the project site. VII. CONCLUSION The proposed project entails the conversion of an existing building within the St. Catherine Parish to a preschool that is expected to accommodate a maximum of 40 students. Primary access to the project site will be provided via an existing driveway off Kawaihau Road with secondary access to be provided via an existing driveway off Hauaala Road. The proposed St Catherine preschool is expected to be completed by Year 2022. With the implementation of the aforementioned recommendations, traffic operations are generally expected to remain similar to without project conditions. Improvements along Kawaihau Road at the intersections with Hauaala Road and Mailihuna Road to convert those intersections into a five-legged peanut roundabout intersection is expected to facilitate traffic flow in the vicinity of the project and accommodate site-generated trips. Although traffic operations in the vicinity are generally expected to remain similar to without project conditions, consideration should be given to ensuring that the pedestrian connections to/from the designated parking areas are accessible in conformance with the American with Disabilities Act requirements.

Beretania Street, Suite 400Honolulu, HI 96826 APPENDIX B LEVEL OF SERVICE DEFINITIONS “Highway Capacity Manual,” Transportation Research Board, 2010. LEVEL OF SERVICE DEFINITIONS LEVEL-OF-SERVICE (LOS) CRITERIA FOR AUTOMOBILES AT A TWO-WAY STOP CONTROLLED (TWSC) INTERSECTIONS LOS for a TWSC intersection is determined by the computed or measured control delay. For motor vehicles, LOS is determined for each minor-street movement (or shared movement) as well as major-street left turns by using criteria shown below. Major-street through vehicles are assumed to experience zero delay. LOS F is assigned to the movement if the volume-to-capacity ratio for the movement exceeds 1.0, regardless of the control delay. The following lists the LOS criteria for a TWSC intersection: LOS A describes operations with a control delay of 10s/veh or less and a volume-to-capacity ratio no greater than 1.0. LOS B describes operations with a control delay between 10s/veh and 15s/veh and a volume-to- capacity ratio no greater than 1.0. LOS C describes operations with a control delay between 15s/veh and 25s/veh and a volume-to- capacity ratio no greater than 1.0. LOS D describes operations with a control delay between 25s/veh and 35s/veh and a volume-to- capacity ratio no greater than 1.0. LOS E describes operations with a control delay between 35s/veh and 50s/veh and a volume-to- capacity ratio no greater than 1.0. LOS F describes operations with a control exceeding 50s/veh and a volume-to-capacity ratio no greater than 1.0 or when the volume-to-capacity ratio exceeds 1.0, regardless of the measurement of the control delay. “Highway Capacity Manual,” Transportation Research Board, 2010. LEVEL OF SERVICE DEFINITIONS LEVEL-OF-SERVICE (LOS) CRITERIA FOR AUTOMOBILES AT A ROUNDABOUT Roundabouts are intersections with a generally circular shaped, characterized by yield on entry and circulation around a central island (counterclockwise in the United States). For a roundabout, LOS is based solely on control delay. The LOS criteria for automobiles in roundabouts is shown below. Roundabouts share the same basic controlled delay formulation with two-way and all-way stop-controlled intersections, adjusting for the effect of yield control. LOS F is assigned to the movement if the volume-to-capacity ratio for the movement exceeds 1.0, regardless of the control delay. The following lists the LOS criteria for a roundabout: LOS A describes operations with a control delay of 10s/veh or less and a volume-to-capacity ratio no greater than 1.0. LOS B describes operations with a control delay between 10s/veh and 15s/veh and a volume-to- capacity ratio no greater than 1.0. LOS C describes operations with a control delay between 15s/veh and 25s/veh and a volume-to- capacity ratio no greater than 1.0. LOS D describes operations with a control delay between 25s/veh and 35s/veh and a volume-to- capacity ratio no greater than 1.0. LOS E describes operations with a control delay between 35s/veh and 50s/veh and a volume-to- capacity ratio no greater than 1.0. LOS F describes operations with a control exceeding 50s/veh and a volume-to-capacity ratio no greater than 1.0 or when the volume-to-capacity ratio exceeds 1.0, regardless of the measurement of the control delay.

IV.PROJECT DESCRIPTION a.Existing Condition of the Structure The existing U-shaped structure is approximately 4,000 sq.ft.and is located behind St.Catherine Parish.The current interior maintains a dormitory style layout in the middle of the building with individual bedrooms and restrooms on both sides of the hallway.The wings of the U-shaped building have common areas including a kitchen,dining area,multi-purpose rooms,and storage shed space. The exterior of the building is primarily constructed of masonry walls and has a hip style roof with asphalt shingles and glass jalousie windows. a.Proposed Project Description Kaua'i Historic Preservation ReviewCommission (KHPRC) November 18,2021 Meeting St.Catherine Nunnery Bullding Renovations for Kamehameha School TMK:(4)4-6-015:058 HPRC-2022-5 Page3 The applicant,Kamehameha Schools,plans to lease the existing church building for a preschool operation.Interior and exterior improvements are being proposed to accommodate the schooluse. Proposed Exterior Improvements: •Roof o Replacement of existing shingle roofing with new similar materials o New gutters o New extension of the roof for the covered walkway •Windows o Removal of all existing jalousie windows and replacement with new vinyl jalousie windows o Conversion of window openings to doors where required •Doors o Removal of all existing doors and replacement with new metal doors (front entry and back)and new sliding doors (back). •New Play Area o New fenced in play area with concrete pad on the south end of the building •New Covered Walkway o New concrete pad and roofline extension to create a covered walkway along the south wall of the building •New Septic System •Paving Existing Driveway •New ADA walkway on the North side of the building •Other miscellaneous repairs to the building including but not limited to spalling,framing,etc. Proposed Interior Improvements: •Reconfiguration of the Interior Layout o Demolition of the existing dormitory style layout o Installation of new partitions to create two classrooms, restrooms,offices,meeting space,and a reception area Kaua'i Historic Preservation Review Commission (KHPRC) November 18,2021 Meeting St.Catherine Nunnery Building Renovations for Kamehameha School TMK:(4)4-6-015:058 HPRC-2022-5 Page4 •New Plumbing to replace the existing entirely •Replacement of electrical system to replace the existing entirely •Structural improvements to existing roofing trusses to accommodate interior improvements and upgrade structural integrity V.TRIGGER FOR KHPRC REVIEW AND HISTORIC PROFILE Hawai'i Revised Statutes (HRS)§6E-2defines "Historic property"as "any building,structure,object,district,area,or site,including heiau and underwater site,which is over fiftyyears old." Hawai'i Administrative Rules Title 13 defines "Significant Historic Property"as"any historic property that meets the criteria"for listing on the Hawai'i Register of Historic Places under HAR 275-6(b)or HAR 2846(b). VI.EVALUATION OF HISTORIC SIGNIFICANCE a.Site/Building/Structure/Object is NOT Listed on Register -State and/or National Register b.The property is NOT located in a Historic District c.The propertyJS over 50 years old and ]S by law defined as a "historic property." d.The subject property IS NOT included on the KHPRC Inventory List e.Evaluation of Significance Under the Criteria for listing to the National or State Register of Historic Places Under the criteria for listing a property on the State and National Registers of Historic Places,the historic nature or significance of the site/building/structure/object may be assessed as follows: •Criteria A.The property is associated with events that have made a significant contribution to the broad patterns of our history; Based on the information gathered by the Planning Department,it does not appear that the property is associated with events that have made a significant contribution to the broad patterns of our history.Therefore,the historic property is unlikely to meet the National Register Criteria A. Kaua'i Historic Preservation Review Commission (KHPRC) November 18,2021 Meeting St.Catherine Nunnery Building Renovations for Kamehameha School TMK:(4)4-6-015:058 HPRC-2022-5 PageS •Criteria B.The property is associated with the lives of significant persons in our past; Based on the information gathered by the Planning Department,the subject property is not associated with the lives of significant persons in our past.Therefore,the subject property does not qualify under the National Register Criteria B. •Criteria C.The property/structure/building embodies the distinctive characteristics of a type,period,or method of construction,or that represent the work of a master,or that possess high artistic values,or that represent a significant and distinguishable entity whose components may lack individual distinction; Based on limited information,the subject property may meet Criteria C as some aspects of the interior and exterior may have been retained over time. •Criteria D.The property has yielded or may be likely to yield,information important in history or prehistory. Based on the information gathered by the Planning Department,the historic structure is unlikely to yield information important in history or prehistory.Therefore,the property is unlikely to meet the National Register Criteria D. •Criteria E.(Hawai'i Register Only).Important value to native Hawaiian people or to another ethnic group of the state due to associations with cultural practices once carried out,or still carried out,at the property;or due to associations with traditional beliefs,events or oral accounts -these associations being important to the group's history and cultural identity. Based on the information gathered by the Planning Department,the subject property is unlikely to meet the requirements of Criteria E. f.Seven Aspects of Historic Integrity The Department does not maintain historic photos of the existing structure and was unable to obtain additional information from the Kauai Historical Society,St.Catherine's Church,and the public library.However,the Department did find a newspaper article from the Garden Island Kaua'i Historic Preservation Review Commission (KHPRC) November 18,2021 Meeting St.Catherine Nunnery Building Renovations for Kamehameha School TMK:(4)4-6-015:058 HPRC-2022-5 Page6 Newspaper,but the article did not provide information about the physical details of the structure. The Department conducted a site inspection in October (see attached Exhibit A for some of the inspection photos).Based on the Department's observations,it appears that the asphalt roof shingles and the jalousie windows are not original to the structure.In addition,the dormitory-style interior layout appears to be original based on the historical use of the structure. Based on the Department's research,the existing structure may retain some aspects of historic integrity such as the location,design,materials, workmanship,feeling,and association.Although some aspects of the exterior (i.e.roof shingles,jalousie windows)may have lost integrity over time,the Department finds that the dormitory style interior may qualify as a character defining feature that should be documented prior to renovations. VII.RECOMMENDATION Based on the foregoing evaluation and conclusion,the Planning Department recommends that the Kaua'i Historic Preservation Review Commission SUPPORT the proposed renovations as represented. The Commission is further advised that this report does not represent the Planning Department's final recommendation in view of the forthcoming public hearing process whereby the entire record should be considered prior to decision making. The entire record includes but is not limited to: a.Government agency comments; b.Testimony from the general public and interested others;and c.The land owner's response.

This information may relate to an individual historic bridge 198 currently on the Historic Bridge List (Attachment 1), a bridge with an undetermined 199 eligibility status, or a bridge previously considered not eligible. New or updated 200 eligibility of the individual bridge in question will be considered following the regular 201 Section 106 consultation process in 36 C.F.R. § 800.3-4, including notification and 202 involvement of NHOs and the public. If an individual bridge is determined eligible 203 or not eligible per 36 C.F.R. § 800.4(c), HDOT shall maintain the list and add to or 204 remove bridges from the list after consultation. 205 B. HDOT may add non-bridge class structures defined per 23 C.F.R. 650.403 as having 206 an opening measuring along the center of the roadway of less than 20 feet, to the 207 Historic Bridge List (Attachment 1) when the non-bridge class structure has been 208 identified as a NRHP listed, eligible or potentially eligible historic structure following 209 the regular Section 106 process defined in 36 C.F.R.§ 800. 210 VI. APPLICATION OF TIERED ACTIVITIES 211 A. Referencing the Tiered Activities for Historic Bridge Minor Projects (Attachment 2) 212 of this Agreement, Project Managers or Qualified Professional(s) following the 213 Project Review process outlined in Stipulation VII may make an initial evaluation 214 that an undertaking is a type of activity/activities that has no potential to cause effect 215 or no adverse effect on historic bridges and structures on the Historic Bridge List 216 (Attachment 1). As such, the undertaking is limited to the activities specified as a 217 Tiered Activity and meets all of the activity terms and conditions and is not part of a 218 larger undertaking. HDOT may modify or add Tiered Activities (Attachment 2) or 219 the Hawai‘i Historic Bridges Best Practices Manual (Attachment 3) as noted in 220 Stipulation XV (Amendment). 221 B. Tiered Activities require internal review by Project Managers and/or Qualified 222 Professional(s) per the Project Review process outlined in Stipulation VII to 223 PRELIMINARY DRAFT – WORK IN PROGRESS FOR INTER-AGENCY DISCUSSION ONLY 7 Draft PA_HDOT_HistBridge_v8 2021.09.02 determine whether a project meets all of the terms and conditions of the Tiered 224 Activities (Attachment 2) and that no particular circumstances exist that would call 225 for additional review. If no such circumstances exist, the Project Manager and/or 226 Qualified Professional(s) will document their finding that the project does not require 227 any further review and maintain that document in the project file in accordance with 228 Stipulation VII.C (Documenting Effect Findings). 229 C. If the project does not meet the terms and condition outlined in the Tiered Activities 230 for Historic Bridge Minor Projects (Attachment 2), the project does not qualify for 231 the use of this Agreement and shall follow the procedures in 36 C.F.R. § 800. 232 VII. PROJECT REVIEW 233 A. This stipulation outlines the Project Review process to be used by Project Managers 234 and Qualified Professionals for Historic Bridge Minor Projects. It provides a 235 streamlined approach to Section 106 compliance for certain projects, i.e. those limited 236 to activities with a known history of resulting in findings of “No Adverse Effect”. 237 238 B. Through this Agreement, the Signatories establish the following categories of 239 activities as enumerated in the Tiered Activities (Attachment 2) and described in 240 greater detail in the Hawai‘i Historic Bridges Best Practices Manual (Attachment 3): 241 1) TIER 1: Activities Requiring No Further Review (No Potential to Cause Effect) 242 Tier 1 Activities have No Potential to Cause Effects to properties, therefore no 243 further review under this Agreement and the NHPA is required. All such 244 undertakings and determinations will be certified by Project Managers using a 245 Certification Form (Attachment 4) and will be documented, recorded, and 246 reported in accordance with Stipulation VII.C (Documenting Effect Findings) 247 and Stipulation XI (Annual Review, Auditing, and Reporting). 248 2) TIER 2: Activities with Potential Effects but No Adverse Effects 249 Activities with Potential Effects but No Adverse Effects are conditioned upon 250 an activity's consistency with the SOI Standards using the Manual's Tier 2 251 guidance; i.e., no Qualified Professional review required. Tier 2 activities using 252 methods other than those prescribed in the Manual will be Tier 3 requiring 253 Qualified Professional review or are activities requiring SHPD consultation and 254 are not covered by this Agreement. 255 If the Project Manager determines that a Tier 2 undertaking has the potential to 256 cause effects on historic properties but will have no adverse effect due to 257 implementation of the Manual, no further review under this Agreement and the 258 NHPA is required. All such undertakings and determinations made will be 259 certified by Project Managers using a Certification Form (Attachment 4) and 260 documented, recorded, and reported in accordance with Stipulation VII.C 261 PRELIMINARY DRAFT – WORK IN PROGRESS FOR INTER-AGENCY DISCUSSION ONLY 8 Draft PA_HDOT_HistBridge_v8 2021.09.02 (Documenting Effect Findings) and Stipulation XI (Annual Review, Auditing, 262 and Reporting). 263 3) TIER 3: Activities with Potential Effects but No Adverse Effects (Qualified 264 Professional Review Required) 265 266 For Tier 3 activities, Qualified Professional(s) shall assess potential impacts, 267 including archaeological and architectural sensitivity potential, to determine 268 whether a project qualifies for processing under the Agreement. HDOT, County 269 or the project sponsor shall submit sufficient information required for the 270 Qualified Professional(s) to complete the assessment, including a Certification 271 Form (Attachment 4) and supporting materials (topographical maps, historic 272 bridge inventory forms, project plans, as needed). 273 Tier 3 Activities with Potential Effects but No Adverse Effects are conditioned 274 upon the activity's consistency with the SOI Standards using the Manual's Tier 275 3 guidance and approval of Qualified Professional(s). Tier 3 activities using 276 methods other than those prescribed in the Manual and not meeting the approval 277 of the Qualified Professional(s) will require SHPO consultation and are not 278 covered by this Agreement. 279 For activities that are proposed within a designated or potential historic district, 280 the Qualified Professional(s) will review the activities to determine whether 281 they have the potential to alter, either directly or indirectly, the characteristics 282 that qualify, or may qualify, the historic district, as well as the historic bridge 283 or structure, for listing in the NRHP. The Qualified Professional(s) will gather 284 additional information, as necessary for the review of the historic district, 285 including, but not limited to, the NRHP nomination, SHPO records, town 286 websites, as well as county master plans, and other county records, as 287 appropriate. Designated districts will be noted on the Certification Form 288 (Attachment 4). Potential districts shall be treated as eligible resources. To 289 determine whether the activities have an effect on an historic district(s), the 290 Qualified Professional(s) will consider the characteristics that qualify, or may 291 qualify, the historic district for the NRHP following guidance in National 292 Register Bulletin 15: How to Apply the National Register Criteria for 293 Evaluation. 294 If the determination of No Adverse Effect is conditioned upon the undertaking's 295 consistency with the SOI Standards, pursuant to 36 C.F.R. §§ 800.5(a)(2)(ii) or 296 800.5(b), the Qualified Professional(s) will review the plans, drawings, 297 specifications, and any modifications, for consistency with the SOI Standards, 298 document their review in accordance with Stipulation VII.C (Documenting 299 Effect Findings), and will monitor the progress of the undertaking in 300 coordination with the Project Manager and contract personnel. 301 The Qualified Professional(s) will have the responsibility to coordinate with 302 Project Managers and contracting personnel to ensure fulfillment of Section 106 303 PRELIMINARY DRAFT – WORK IN PROGRESS FOR INTER-AGENCY DISCUSSION ONLY 9 Draft PA_HDOT_HistBridge_v8 2021.09.02 stipulations or conditions during construction. All such undertakings and 304 determinations made will be documented, recorded, and reported in accordance 305 with Stipulation VII.C (Documenting Effect Findings) and Stipulation XI 306 (Annual Review, Auditing, and Reporting). 307 If during project planning or construction, the Qualified Professional(s) 308 determine that a Tier 3 activity will or has the potential to cause an adverse 309 effect, the activity will require SHPO consultation and may not be covered by 310 this Agreement, or a review will take place under Stipulation VII.D (Changes 311 to Scope of Project). 312 4) Activities with the Potential for Adverse Effect 313 Projects that do not conform to Tier 1, 2 or 3 guidance shall follow the 314 procedures in 36 C.F.R. § 800 and will not be subject to this Agreement. 315 C. Limitations on Ground Disturbing Activities 316 For Historic Bridge Minor Projects qualifying as Tier 1, 2 or 3 activities, ground 317 disturbances will not take place or be limited as described in this stipulation to avoid 318 or minimize the potential to impact archaeological resources. 319 1) Ground-disturbing activities for qualifying minor projects, including scour 320 countermeasures and foundation repairs, may take place within a strict 10-foot 321 buffer zone, as measured from the edge of the superstructure and substructure 322 of the existing historic bridge or structure. 323 2) Driven poles for signage, guardrails and other types of roadside appurtenances 324 are allowable within the Right of Way and outside of the 10-foot buffer zone 325 for poles with a maximum 4-inch diameter to be driven no more than a depth 326 of 36 inches below existing ground surfaces. 327 3) Laydown yards for qualifying Historic Bridge Minor Projects must be on 328 existing paved areas or unpaved areas protected with matting. 329 4) Any ground disturbing activity not conforming to these limitations will not be 330 covered by this Agreement and shall follow the procedures in 36 C.F.R. § 800 331 or other Section 106 agreements as developed by the lead federal agency. 332 D. Documenting Effect Findings 333 334 For minor projects on Historic Bridges qualifying as Tier 1 or 2 activities, Project 335 Managers will complete a Certification Form (Attachment 4) documenting that the 336 activities qualified under this Agreement. Documentation shall be maintained in the 337 project files and reported in accordance with Stipulation XI (Annual Review, 338 Auditing, and Reporting). 339 PRELIMINARY DRAFT – WORK IN PROGRESS FOR INTER-AGENCY DISCUSSION ONLY 10 Draft PA_HDOT_HistBridge_v8 2021.09.02 For minor projects on Historic Bridges qualifying as Tier 3 activities, Qualified 340 Professionals shall make a finding that the project results in No Adverse Effect on 341 the Certification Form (Attachment 4); HDOT Project Managers shall maintain 342 documentation in the project files and report in accordance with Stipulation XI 343 (Annual Review, Auditing, and Reporting). 344 If a review by Qualified Professional(s) determines that a project is does not qualify 345 as a Historic Bridge Minor Project under this Agreement, HDOT staff shall utilize 346 the Certification Form (Attachment 4) to notify the project sponsor in writing that the 347 project does not qualify for processing under this Agreement, and that the project will 348 be reviewed consistent with 36 C.F.R. § 800. 349 For projects requiring USACE permits, the Certification Form (Attachment 4) will 350 be submitted by the project permittee as evidence of the use of this Agreement. The 351 USACE shall receive project plans, specifications and/or other suitable 352 documentation as needed to verify the applicability of this Agreement. 353 HDOT shall notify FHWA, USACE and SHPO of the use of the Agreement on 354 specific projects in an annual report to the Signatories of this Agreement, as specified 355 in Stipulation XI (Annual Review, Auditing, and Reporting). 356 E. Changes to the Scope of a Project 357 When changes to the scope, design, or implementation of a Historic Bridge Minor 358 Project occur during planning or construction, the Project Manager shall evaluate the 359 revised project and determine if the tier level of the project under this Agreement still 360 applies. If the project remains Tier 1 or Tier 2, the Project Manager shall prepare an 361 updated Certification Form (Attachment 4). 362 The Project Manager shall coordinate with Qualified Professional(s) when those 363 changes result in new activities that meet Tier 3 or non-tiered activity definitions. The 364 Qualified Professional(s) shall be provided with sufficient information and time to 365 allow for a complete reassessment of the modified project. An updated Certification 366 Form (Attachment 4) shall be prepared and included in the project file. The 367 Certification Form (Attachment 4) shall be submitted to the USACE when it affects 368 a USACE permit. 369 As appropriate, the Qualified Professional(s) shall evaluate the revised project and 370 alert the project sponsor as to whether: 1) the project continues to qualify for 371 processing under the Agreement, and additional or revised certification forms are 372 required, or 2) the project no longer qualifies for this Agreement and must follow 36 373 C.F.R. § 800. If the project no longer qualifies under the Agreement, the lead federal 374 agency and/or project sponsor shall notify the SHPO and initiate a Section 106 375 review. 376 PRELIMINARY DRAFT – WORK IN PROGRESS FOR INTER-AGENCY DISCUSSION ONLY 11 Draft PA_HDOT_HistBridge_v8 2021.09.02 VIII. EMERGENCY SITUATIONS 377 Historic Bridge Minor Project activities, as defined in Tiered Activities (Attachment 2), 378 may in some instances be applicable during emergencies. This stipulation provides for an 379 expedited use of the Agreement with certification taking place within 60 calendar days of 380 the commencement of work on Tier 1, 2 or 3 activities. All such use of this Agreement to 381 streamline Section 106 in an emergency shall be consistent with, and subject to, the 382 “Emergency Situations” provisions of Section 106 (36 C.F.R. § 800.12) or other Section 383 106 emergency agreements that may be entered into by FHWA or USACE and the parties 384 to this Agreement. Emergencies are defined as occurrences that require emergency 385 highway system and facility repairs that are necessary to 1) protect the life, safety, or health 386 of the public; 2) minimize the extent of damage to the highway system and facilities; 3) 387 protect remaining highway facilities; or 4) restore safe roadway travel. The following 388 stipulations apply to emergency situations: 389 A. Repairs to address emergency situations as defined above can occur regardless of 390 funding category, and regardless of declarations made by federal, state, or local 391 agencies. 392 B. If the emergency repair project applies to historic bridges or structures that are 393 included on the Historic Bridge List (Attachment 1), the Project Manager may apply 394 Tier 1 and 2 activities and complete the Certification Form (Attachment 4) within 60 395 calendar days of the commencement of work. 396 C. If the emergency repair project applies to historic bridges or structures that are 397 included on the Historic Bridge List (Attachment 1), the Project Manager, in written 398 communication with a Qualified Professional(s), may apply Tier 3 activities and the 399 Qualified Professional(s) may complete the Certification Form (Attachment 4) within 400 60 calendar days of the commencement of work. 401 D.

The goal is to streamline the Section 106 review process and regularize it to facilitate the use of federal aid for historic bridge minor projects. The Agreement applies to historic bridges and structures listed on the Historic Bridge List; defined as those currently listed, eligible or potentially eligible for listing on the NRHP either individually or as contributing resources to listed, eligible or potentially eligible historic district. It will not address major rehabilitation or replacement projects. It exempts ground-disturbing activities within a strict 10-foot buffer zone, presumed to be previously disturbed by the initial bridge construction, as measured from the edge of the superstructure and substructure of the existing historic bridge or structure from further review. The Agreement addresses a range of historic bridge maintenance, repair, and minor rehabilitation activities (i.e., undertakings). The Best Practices Manual outlines general design and technical recommendations to assist in applying the Secretary of the Interior's Standards for the Treatment of Historic Properties (SOI Standards) to specific minor bridge projects. Together, they provide a framework and guidance for decision-making for repair and maintenance of the historic bridges and their historic character-defining features. Project Review The Agreement applies only to the Tiered Activities for Historic Bridge Minor Projects. Project Manager(s) or Qualified Professional(s) (in accordance with Stipulation 3.A) following the Project Review process outlined in Agreement may make a determination that an undertaking is an activity that has no potential to cause effect or no adverse effect on bridges and structures on the Historic Bridge List. If the project does not meet the terms and condition outlined in the Tiered Activities for Historic Bridge Minor Projects, the project does not qualify for this Agreement and shall follow the procedures in 36 C.F.R. § 800. The Best Practices Manual provides guidance and outlines the approach to historic properties review by Project Managers and Qualified Professionals for Historic Bridge Minor Projects and Introduction 2 9/02/2021 provides a streamlined approach to Section 106 compliance for certain projects limited to activities with a known history of resulting in findings of “No Adverse Effect”. Work activities will be divided into tiers based on their potential to cause effects to historic resources. For all projects undertaken pursuant to this Agreement, the following requirements shall be observed: TIER 1: Activities Requiring No Further Review Tier 1 Activities have No Potential to Cause Effects to historic properties, therefore the activity may proceed with no further review under this Agreement and the NHPA. All such undertakings and determinations made will be documented, recorded, and reported in accordance with Agreement Stipulation XI (Annual Review, Auditing, and Reporting). TIER 2: Activities with Potential Effects but No Adverse Effects Activities with Potential Effects but No Adverse Effects are conditioned upon an activity's compliance with the Secretary of the Interior’s Standards for the Treatment of Historic Properties (SOI Standards) using the Best Practices Manual's Tier 2 guidance. Activities using methods other than those prescribed in the Manual shall be Tier 3 requiring Qualified Professional review or require SHPO consultation and are not covered by the Agreement for Hawaiʻi Historic Bridge Minor Projects. If the Project Manager determines that a Tier 2 undertaking has the potential to cause effects on historic properties but will have no adverse effect due to implementation of the Manual, no further review under this Agreement and the NHPA is required. All such undertakings and determinations made will be documented, recorded, and reported in accordance with Agreement Stipulation XI (Annual Review, Auditing, and Reporting). TIER 3: Activities with Potential Effects but No Adverse Effects Tier 3 Activities with Potential Effects but No Adverse Effects are conditioned upon the activity's compliance with the SOI Standards using the Best Practices Manual's Tier 3 guidance and the approval of Qualified Professional(s). Tier 3 activities using methods other than those prescribed in the Manual and not meeting the approval of the Qualified Professional(s) shall follow the procedures in 36 C.F.R. § 800 and will not be subject to this Agreement. The Qualified Professional(s) shall assess potential impacts, including archaeological and architectural sensitivity potential, to determine whether a project qualifies for processing under the Agreement. HDOT, County or the project sponsor shall submit sufficient information required for the Qualified Professional(s) to complete the assessment, including a Certification Form and supporting materials (topographical maps, historic bridge inventory forms, project plans, as needed). If the determination of no adverse effect is conditioned upon the undertaking's consistency with the SOI Standards, pursuant to 36 C.F.R. §§ 800.5(a)(2)(ii) or 800.5(b), the Qualified Professional(s) will review (and document their review thereof) the plans, drawings, Introduction 3 9/02/2021 specifications, and any modifications, for consistency with the SOI Standards, and will monitor the progress of the undertaking in coordination with the project manager and contract personnel. The Qualified Professional(s) will have the responsibility to coordinate with project managers and contracting personnel to ensure fulfillment of Section 106 stipulations or conditions during construction. All such undertakings and determinations made will be documented, recorded, and reported in accordance with Agreement Stipulation XI (Annual Review, Auditing, and Reporting). Projects with the Potential for Adverse Effects Activities that do not conform to Tiers 1, 2 or 3 shall require additional approval and shall follow the procedures in 36 C.F.R. § 800 and will not be subject to this Agreement. If during project planning or construction, the Qualified Professional(s) determine that a Tier 3 activity will, or has the potential to, cause an adverse effect, it will require SHPO review under Agreement Stipulation VII.D (Changes to Scope of Project).

(End of Chapter) 1 Hawai’i Historic Bridge Minor Project Programmatic Agreement Chapter 3 Roadway 3.1 Roadway Surface / Wearing Surface 3.1.1 Wearing Surface and Paving Intent: Bridge pavement maintenance contributes to vehicle safety and is often essential to the longevity of a historic bridge as it can protect against water infiltration to the structure below. Principles: Degraded deck wearing surfaces should be routinely maintained and replaced when a specified threshold is reached, and when funding permits. Periodic repair or replacement of a historic bridge’s roadway surface should be done with like materials (ex: replace wood with wood) per the Secretary of the Interior’s Standards for Treatment of Historic Properties. Roadway surface maintenance varies by material. Concrete: The determination to maintain, repair, or replace a concrete wearing surface is based on the percentage of delamination and/or spalled surface present, chloride contamination, and condition of the deck soffits. Testing may be required to verify the condition of the concrete wearing surface, which may be done by chain drag, thermographic imagery, or ground penetrating radar and should be performed by qualified professionals (see Chapter 4 for additional information on concrete testing). Surface replacement should be done when the existing concrete surface is more than 30 to 40% spalled or delaminated. There are a variety of repair strategies that may be used depending on the existing conditions: Tier 1 Activities Replace an existing concrete deck or wearing surface with new concrete. Tier 2 Activities 2 Repair of an existing concrete deck or wearing surface. This may be done using a dissimilar material, such as Asphaltic Concrete, as a temporary and urgent measure to prevent further degradation of the surface. Permanent repair using concrete repair material should then be done within 90 days. Where spalling is present, specific repair techniques are vital to the longevity and effectiveness of the work. Refer to Section 2.3.2 for information on Spall Repair. Structural overlays may be required if significant delamination and/or deterioration is present. Placing a new concrete surface over an existing one will lead to extra loading on the structure. Refer to section 3.1.4 below for wearing surface loading considerations. Tier 3 Activities Repair or replacement of a concrete wearing surface with a dissimilar material is not recommended. Approval from an SOI Qualified Professional is required to ensure that the wearing surface is not a contributing characteristic to the historic bridge. Thin polymer overlays may be used for concrete wearing surfaces with moderate traffic and chloride concentration levels at the steel reinforcement mat below sub-threshold levels but should be approved by an SOI Qualified Professional prior to installation. Asphaltic Concrete (AC): The determination to maintain, repair, or replace an AC wearing surface is based on the percentage of delaminated surface or rutting depths. Testing may be required to verify the condition of the AC wearing surface, and testing may be done by thermographic imagery or ground penetrating radar and should be performed by qualified professionals (see Chapter 4 for information on AC testing). If more than 30 to 40% of the wearing surface is delaminated, resurfacing should be considered. Prior to placement of new AC overlay, a waterproofing membrane should be placed on top of the underlying deck, and subsequent asphalt overlays must either replace this membrane or ensure that the membrane is not damaged. Tier 1 Activities AC patching of existing AC wearing surface. Tier 2 Activities Repair or replacement of existing AC wearing surface with new AC. Subsurface should be clean and free of loose material prior to installation of new wearing surface. Ensure water proofing membrane is applied following manufacturers’ recommendations. Tier 3 Activities Replacement of existing AC wearing surface with dissimilar material. Steel Grid Decks: Steel grid decks are susceptible to fatigue cracking and intermittent welded repairs must be performed. When steel grid decks are replaced, new members have greater fatigue resistance and close inspection of 3 the stringer top flanges should be performed as wear grooves may be present. Stringer replacement should be strongly considered if grooves, cracks, or section loss are present. Refer to Section 2.4.3 for additional information. Tier 1 Activities Welded repairs of fatigue cracks in existing grating or welded repairs to broken or detached areas of the grating. Tier 2 Activities Replacing existing grating with new of similar design and material properties. Inspection of stringer top flange should take place when this work is performed. If damage is found, stringers can be replaced in-kind. If not using in-kind or similar stringers, refer to Tier 3 instructions below. Tier 3 Activities Replacing existing grating with a different design or material properties. Compatibility should be checked between the new grating and the existing support structure. Inspection of the existing stringers is particularly vital as the existing grating may have caused damage over time. If existing stringers are to be replaced with dissimilar members, it should be approved by an SOI Qualified Professional prior to commencement of work. There may be scenarios where augmentation or alteration of steel grid decks are required to achieve a higher level of tire traction. Approval of an SOI Qualitied Professional must determine whether the existing deck is a character defining feature of the bridge. Wood Decks: Wood deck wearing surfaces should be routinely replaced when there is evidence of material deterioration. Dimensions of replacement members should match those of the member(s) being replaced. Replace wood members with like species whenever possible. Tier 1 Activities Replacement of existing timber wearing surface with new boards matching the existing dimensions and species whenever possible. Tier 2 Activities (No activities apply) Tier 3 Activities Replacement of wearing surface with dissimilar material or different size members. 3.1.2 Surface Sealing Intent: Sealers prolong the longevity of the wearing surface. Routine application of sealers is encouraged, provided they do not alter the appearance of the wearing surface. Principles: Processes for wearing surface sealing vary by material. Concrete: Surface repair and preparation should be performed prior to the application of concrete sealers. 4 Tier 1 Activities (No activities apply.) Tier 2 Activities Concrete must be clean and free of loose material prior to sealing. Power washing is recommended, provided it does not damage the surface. Unless using a crack- filling sealer (such as methacrylate), surface cracks and spalls should be repaired prior to sealing (see Sections 2.3.1 and 2.3.2). Surface should be dry before applying sealer. Apply sealer only if the air temperature is within the manufacturer’s recommended range. Allow to cure prior to use. Tier 3 Activities Applying a new sealer to an existing concrete surface that causes darkening or discoloration should be approved by an SOI Qualified Professional prior to commencement of work. Material test sampling may be required. Asphaltic Concrete (AC): Sealing is an effective way to renew old asphalt surfaces that have become dry and brittle with age, and to seal small surface cracks and surface voids. Tier 1 Activities Application of sealer to an existing AC wearing surface. Tier 2 Activities Sealing should be done as soon as any signs of cracking, voids, or other distress are observed. Cracks in the existing AC wearing surface should be repaired prior to sealing. Do not over fill cracks with repair material. The top of crack repair material should be 1/8 to 1/4 inch below the surface of the surrounding AC. Once the cracks are filled with the repair material, the surface can be thoroughly sealed. Seal only when the existing surface is dry and free of loose material, using a light application of asphalt emulsion. Vehicles must be kept off the seal until it is absorbed into the existing AC surface, following manufacturers’ recommendations. Tier 3 Activities (No activities apply.) Steel Grids: Refer to Section 5.2.3 for information on painting steel. Tiers 1-3 Activities (No activities apply.) Wood: Protective systems are necessary to resist decay and rot in timber bridge decks. There are a variety of agents and techniques used historically to achieve decay resistance, including the use of specific species with natural decay resistance, chemical and pressure treatment / fumigation, paints, and water repellants. Tier 1 Activities Routine reapplication of water repellant sealer over existing applications of the same composition and color matching. Tier 2 Activities 5 Any new sealer should match the original as closely as possible without color change aside from a slight darkening. Reapplying water repellant sealers in the field is part of routine maintenance. This should begin by removing anything that might inhibit the new sealer from penetrating into the wood. Prepare the existing wood by removing any dirt, mildew, loose and weathered wood fibers and old sealers. Application of a stripping agent may be necessary to remove severe weathering, graying, black mildew and failed or discolored oil-based sealer. A quick sanding with 80 grit after stripping will remove any wood fuzz that inevitably appears after stripping. Apply new sealer per manufacturer’s recommendations, making sure the air temperature is within the recommended range. Any new sealer should match the historic sealer in level of transparency, tone, and color as closely as possible. Field application of fumigants does not affect the outward appearance of the wood and needs no further guidance. For painted surfaces, the new paint color should match that of the original. Prepare the existing surface by removing any dirt, mildew, loose and weathered wood fibers, and failing paint. Refer to Section 5.2.4 for additional information on painting wood. Tier 3 Activities Application of sealer when sealer causes changes to the color or texture of the existing wood wearing surface. 3.1.3 Surface Drainage Intent: Keeping roadway surfaces free from standing water is essential for vehicle safety and protecting against water infiltration to the structure below. Principles: Effective drainage is crucial to maintaining a safe roadway as well as a sound structure. At the deck level, scuppers and other drainage collectors must remain free of dirt and debris. Keeping drainage pathways open and clear should be a part of routine maintenance. Measures used for such maintenance should be non-invasive. Cleaning: Tier 1 Activities Clean and wash out roadway and drainage openings to remove any accumulated debris and ensure a clear pathway for water runoff. Tier 2 Activities The continuity of the existing drainage system should first be checked to ensure that leakage into the structure is not occurring. All cleaning methods should not damage the bridge or drainage system. Cleaning can be done using hand tools, or by using compressed air or pressurized water (maximum 1,500 psi). If pressurized water is used, test the water pressure in an inconspicuous area. If damage occurs, reduce water pressure and repeat testing until no damage is detectable. Where standing water accumulates, repairs to existing wearing surface may be necessary. Refer to sections above regarding wearing surface repairs. Tier 3 Activities 6 If ponding occurs on a roadway surface, the surface may need to be resurfaced in part or whole to ensure proper drainage. Refer to Section 3.1.1 above for information wearing surface replacement. Drainage Pathways: Routine inspection of existing drainage pathways is recommended to determine whether they are clear and operating properly. Ideally, drainage pathways will carry storm water away from the roadway and structure and safely deliver it away from the structure without causing structural damage or subsequent erosion. Additionally, ensuring there are no leaks or entry points for water to enter into the interior of the structure. Tier 1 Activities Visual inspection and flow testing of drainage pathways. Clearing pathways of dirt and debris using non-invasive methods. Tier 2 Activities Use of approved mechanical devices to open clogged drain lines. This might include the use of a rooter or auger, although care should be taken not to damage the side walls of the drainage lines. Maintenance of existing drainage lines, which might include the repair or replacement of drainpipes with in-kind material. Tier 3 Activities Replacement of drain lines with dissimilar materials. There are cases where the existing drainage pathways are designed to deliver storm water directly into contact with the historic structure, causing deterioration (Figure 3.1). This should be addressed, and any alterations should be approved by an SOI Qualified Professional. Photo: CONSOR Engineers, LLC 3.1.4 Wearing Surface Loading Intent: The weight of wearing surfaces contributes to the dead load supported by the deck, superstructure, and substructure. Where subsequent wearing surfaces are added on top of existing, the added dead load reduces the structure’s live load capacity, that can result in weight restrictions and weight limit posting. Vertical layering of wearing surfaces should be limited so that load limits are not exceeded 7 or compromised. Reducing the layering and weight of the wearing surface extends the useful life of a historic bridge. Principles: Adding a new wearing surface over an existing one may have consequences for load capacity of the bridge overall and should be evaluated by a qualified engineer prior to doing work. Consider the following when adding new wearing surfaces over existing: -Additional load on existing deck, superstructure, and substructure. -Flattening of vertical profile or camber occurring within bridge limits. -Continuity of drainage pathways from wearing surface. -Transitions to approaches. -In order to avoid damage to exiting curbs, ensure that the curbs at the parapets are not covered or buried. Further consideration of wearing surface loads varies by material. Additional Comment: If the existing wearing surface depth is unknown, testing may be required. The use of ground penetrating radar or small diameter drill bit may be used to determine or measure the depth of the wearing surface any subsequent layers below. Concrete: Concrete wearing surface overlays that do not increase a structure’s dead load if the existing concrete top surface that is removed by scarification is equal to or less than the thickness of the overlay. Tier 1 Activities Removal of non-original wearing surfaces layered on top of a historic bridge’s original concrete wearing surface or the original concrete deck. In-kind replacement of an existing concrete wearing surface. Tier 2 Activities Adding a new wearing surface over an existing of the same material, provided that all considerations listed above have been satisfied. Tier 3 Activities Adding a new wearing surface of dissimilar material or when all considerations listed above have not been satisfied. Asphaltic Concrete (AC): When AC overlay resurfacings are planned, determine the thickness of the existing wearing surface and verify that it does not exceed permissible thicknesses noted on the original construction drawings. If no construction drawings are available, a maximum combined 3-inch wearing surface that includes new and existing overlays is recommended. Tier 1 Activities Removal of non-original wearing surfaces layered on top of a historic bridge’s original wearing surface. In-kind replacement of an existing AC wearing surface. Tier 2 Activities 8 Adding a new AC wearing surface of the same material, provided that all considerations listed above have been satisfied. Tier 3 Activities Adding a new AC wearing surface over an existing of dissimilar material or when all considerations listed above have not been satisfied. 3.2 Railings and Parapets 3.2.1 Bridge Railing and Parapet Repairs Intent: Historic bridge railings are varied in material and configuration and cannot be generalized. Often, railings do not meet crash, height or closure requirements, and Section 3.2.2 below deals with such upgrades. The intent of this subsection is to address in-kind repair of damaged, deteriorated, or missing components of existing railings that do not require upgrades. If guidance in this section is followed, the intent of the Secretary of the Interior’s Standards for the Treatment of Historic Properties will be met. Principles: Maintaining the character of railings is of particular importance as they are visible elements of historic bridges, and often considered character-defining features contributing to the bridge’s historic significance. A railing’s design, workmanship and materiality usually speak to a bridge’s period of significance and the era when the bridge entered service. Therefore, the goal of in-kind railing repair is to maintain the original as closely as possible and minimize alterations. All new work should match the old in material, design, scale, color, finish, and texture. The following addresses in-kind railing repair considerations by material. Stone: Using the original material to make repairs is preferred. Also refer to Section 2.2.2 for stone and mortar repair. Tier 1 Activities (No activities apply.) Tier 2 Activities Rebuild damaged parapets and copings with the original stones, if possible. These stones may have been dislodged and are sometimes found near the bridge or in the streambed. If it is not possible to reuse the original stones, then they should be replaced in-kind, matching the existing stones in type, size, cut, texture/finish, and color. The repaired section should replicate the coursing of the existing section. Repointing of mortar should match the existing mortar in strength, tooling, texture, and craftsmanship. Tier 3 Activities Repair or replacement of missing or deteriorated stones with new material matching existing, when the previously existing material cannot be found or used. Repointing using mortar dissimilar to existing characteristics of type, color, strength, and tooling. 9 Concrete: Minor repair of railings and parapets is most commonly necessitated by spalling. Where spall repairs are required at corners, edges, or decorative features, the finish concrete lines, corners, edges, and features shall be continuous and seamless in fial appearance and have any discontinuities, breaks, speparations, or jogs. Tiers 1-3 Activities Refer to Subsection 2.3 for Spall Repair guidance. Metal: Metal composition and fastening technologies have changed over time. Prior to work commencing, the type of metal should be identified as each metal has its own properties. Replacement using in-kind material and dimension is preferred whenever possible (ex: aluminum for aluminum). Tier 1 Activities (No activities apply.) Tier 2 Activities Replacement of older, worn-out or damaged iron or steel railing components with newer steel alloys is permitted as long as the replacement railing components are of a similar dimension. In the case of iron, the material is no longer readily available to replace in-kind. Carbon or mild steel may be used instead, provided the sectional dimensions match the original. Rivets may be replaced using buttonhead bolts, with the buttonhead facing outward toward the railing’s most visible elevation. Refer to Section 2.4.4 for information on rivets. Square head and hex-head bolts should be replaced in-kind with bolts having heads of similar dimension. Any new finish system must match the existing in appearance relative to color and sheen. Also refer to Section 2.4 for additional information. Tier 3 Activities Any replacement of members or elements having dissimilar material, finish, dimensions, or attachment methods, number, or locations. Wood: It is common for historic wood bridges to be painted or coated. If coated, all repairs to the railing should be painted or coated to match the existing color, texture, and sheen. Also see Section 2.5 for information. Tier 1 Activities (No activities apply.) Tiers 2-3 Activities Damaged or deteriorated wood railing components may be replaced in-kind provided the dimensions and finish match the existing. Substitution of species or newer preservative treatments is permissible particularly when they are more environmentally sustainable. Fastening hardware should be matched as closely as possible to the hardware of the existing railing. Ties 3 Activities Replacement of deteriorated wood members with members of different material, dimensions, species, or finish. If railings are painted, see guidance above. 3.2.2 Bridge Railing Upgrade Intent: Upgrading historic railings to meet current standards typically involves alteration to the materiality, design, scale, color, or finish in the railing 10 components, potentially impacting the historic characteristics of the bridge. Railing upgrades are defined as those projects that do not result in railing replacement. Since there are many types of railings and upgrade scenarios, railing upgrades of historic bridges should be handled on a case-by-case basis in consultation with a SOI Qualified Professional. If a SOI Qualified Professional determines that a bridge’s railings are contributing to the bridge’s historic characteristics, then a full railing replacement of must match the existing or will not be allowed under this agreement. Principles: There are a number of common scenarios encountered and approaches that may meet the Secretary of the Interior’s Standards for the Treatment of Historic Properties under the category of ‘Rehabilitation’ when considering railing upgrades. A railing upgrade project should meet at least one of the following criteria and must be reviewed by an SOI Qualified Professional to determine if it is non-adverse per the provisions of the Minor Historic Bridge Projects Programmatic Agreement: -Adding strength to an existing railing to meet AASHTO and HDOT standards. -Adding new barrier inboard of existing barriers to preserve the original barrier. - Replacing an existing railing with a compatible new railing when it is determined that the existing railing is itself a replacement that does not contribute to the historic bridge’s significance (e.g., a bridge that originally had concrete parapets to its period of significance of 1920 but had those parapets replaced less than 50 years ago by metal thrie-beam guiderails). -Adding height and/or member density to meet pedestrian guardrail requirements. Tiers 1-2 Activities (No activities apply.) Tier 3 Activities Replacement or modification of existing barriers or railings to meet current safety standards, maintaining the historic integrity of the existing, and meeting at least one of the criteria listed above. 3.2.3 Embossed or Impressed Writing Intent: It is not uncommon for historic bridges to have permanent inscriptions such as construction dates cast into or mounted on them. These are historically significant, and their maintenance is significant to the historic character of the bridge overall. As material ages, these inscriptions require special care in preserving their appearance and maintenance. Principles: Maintenance of historic inscriptions is unique to the material being used and requires thoughtful and skilled care. Tier 1 Activities (No activities apply.) Tier 2 Activities Cleaning and repairing existing plaques and inscriptions should be done using non- invasive methods. Refer to Chapter 2 for information on the cleaning of specific materials. Tier 3 Activities 11 Altering, moving, obscuring, or replicating existing impressions, or adding new writing required the approval of a SOI Qualified Professional. 3.2.4 Attaching Approach Guardrails Intent: Given the variety of guardrails and bridge railing designs in the historic bridge inventory, there are no prescriptive solutions that can be provided. As such, approval of a SOI Qualified Professional is required. Principles: If approach rails exist and are attached to a historic bridge then two things must be determined. First is whether they meet current AASHTO and HDOT standards. Second, it should be determined whether the approach rails are of historic significance. Both cases require the consultation and approval of an SOI Qualified Professional to move forward. When adding new approach rails or upgrading existing ones, it should be done in a way that is consistent with, and complementary to the historic bridge. This too will require the approval of an SOI Qualified Professional. Tier 1 Activities (No activities apply.) Tier 2 Activities In-kind repairs or replacement of existing guardrail connections at the parapet/railing ends. Tier 3 Activities Replacement of approach guardrail connections to meet current safety standards, while maintaining the historic integrity of existing. Attaching approach guardrails to the bridge parapet/railing when not previously attached. 3.3 Sidewalks 3.3.1 Elevated Sidewalks and Accessibility Intent: Maintenance of existing sidewalks is covered well in other sections in this document relating to the treatment of deteriorating materials, and their assigned tier level is also applicable here. If existing sidewalk(s) are elevated above the roadway, they will need to address current codes regarding accessibility whenever possible. This may require the installation of ramps on bridge approaches, or the provision of an alternative pathway along an accessible route. Principles: If it is determined that all or part of a historic bridge is required to meet the Americans With Disabilities Act (ADA), then all prescribed design criteria must be followed for all accessible pedestrian routes across the bridge, including pathway width, slope, railings, and approaches. Exceptions may be granted provided it can be demonstrated that satisfying these requirements cannot be achieved without adverse effects to the historic bridge, or the cost of the necessary alterations exceeds an established percentage of the overall budget for the work being proposed. The granting of such exceptions is outside the scope of this agreement. Other than routine material maintenance of existing sidewalks, all sidewalk work must be approved by an SOI Qualified Professional. 12 Tier 1 Activity (No activities apply.) Tier 2 Activity Maintenance or repair of existing materials, including spalling, deterioration, or section loss with in-kind materials and finishes, and adhering to the intent and principles stated above. Refer to Chapter 2 for additional information on repair of materials. Tier 3 Activity Maintenance or repair of existing materials, including spalling, deterioration, or section loss with dissimilar materials and finishes. Pathway modifications to meet accessibility standards. 3.3.2 Sidewalks Level with Roadway Intent and Principles: Where sidewalks are provided level with the roadway, delineation and separation of automobile and pedestrian traffic must meet AASHTO and HDOT regulations. Refer to Chapter 5 regarding paint striping. The addition of roadway markers requires the approval of a SOI Qualified Professional. Tier 1 Activities (No activities apply.) Tier 2 Activities All maintenance of existing sidewalks. Tier 3 Activities Modifications to existing or installation of new pedestrian pathways. 3.4 Traffic Control 3.4.1 Traffic Control Lights Intent and Principles: The presence of traffic control devices, such as traffic signals, traffic gates, navigational lights, etc., on bridges is somewhat rare, but when present can contribute to the bridge’s historic character. Whenever possible, they should be repaired or replaced with in-kind fixtures. Tier 1 Activities In-kind repair or replacement of fixture components. Tier 2 Activities (No activities apply.) Tier 3 Activities Replacement of fixtures or components with non-matching fittings. If new or temporary traffic control devices are being added where none previously existed, they should be installed in a way that does not leave any permanent marks on the historic bridge.
