PROJECT OBJECTIVES In accordance with FEMA-4340-DR-VI Hazard Mitigation Grant Program (HMGP) - Project 4340- 0010, VITEMA is proposing to demolish their old, existing facilities and construct a new four- story Emergency Operations Center (EOC) and Safe Room at the existing building footprint. This project will redevelop a previously disturbed site. The facility will serve as the main offices for VITEMA and the 911 Emergency Call Center (ECC). The facility will operate daily during normal business hours and full-time during disaster events. The intention of this project is to serve VITEMA’s daily operational and emergency needs so that the Agencies may serve the residents of the entire US Virgin Islands. This facility will be the primary employment center for emergency response-related employees currently located in Christiansted. The facility will operate as an emergency coordination center. No EMS or fire emergency vehicles will be present on site. The number of staff at the facility during daily operations is expected to range between 40 and 50. During emergency events staffing is estimated to increase to 200 where 24 – 48-hour safe room operations will be in effect. A portion of the new facility will be built in accordance with the current building code requirements for a FEMA critical facility and safe room (FEMA P-361 and International Code Council (ICC) 500) to allow for VITEMA, and other emergency personnel to shelter-in-place during disaster events, providing amenities for 24-hour continuous operations. Ground disturbance will include demolition and environmental remediation of existing site features (tennis courts, parking lots) to make way for new surface parking, drainage, water, and sanitary sewer infrastructure. New backup generators, cisterns, and on-site lift station will allow the building to function self-sufficiently during disasters. The project will comply with applicable US Virgin Islands and Federal regulations per the FEMA Record of Environmental Consideration (REC). Compliance with the Coastal Zone Management Act includes obtaining a consistency determination from the Virgin Islands Department of Planning and Natural Resources. Other relevant laws and environmental regulations include a RCRA compliant disposal permit and approval letter for proper handling and removal of hazardous materials and disaster generated debris. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 10 IV. PROJECT DESCRIPTION Summary of Proposed Activity A new, four-story Emergency Operations Center (EOC) and Safe Room building will be constructed aligned with the L-shaped building footprint of the existing Hermon Hill VITEMA complex. The new north and south wing building area, with connecting corridor is: • Total building size – 30,052 square feet • Safe Room – 4,665 usable square feet A one-story, approximately 2,500 square foot enclosure for mechanical equipment will also be included. The basement level will include cistern, MEP support facilities, and storage of supplies and equipment required for EOC activation. The size of the property is 4.58 acres of which 4.00 acres will be disturbed. The new building sits atop the existing building footprint. The north wing rebuild will include ICC 500 and P-361 structural building requirements, back-up power, provision of sanitation and food preparation areas due to the prolonged use of a hurricane safe room, area for peer review of engineering documents, and all other safe room requirements including provision of sufficient parking to accommodate safe room capacity. This safe room compliant structure will also include the 911 Call Center in order to meet the code requirements for that use. Storm Shelter vs Safe Room The facility is not designed, nor is it funded, as a public safe room. The VITEMA safe room design is based on the population at risk that needs protection. In this case the population at risk is: 1) FEMA/Homeland Security personnel, 2) VITEMA coordinating emergency planning and response personnel, 3) US VI 911 Emergency Call Center personnel dispatching calls for local police, fire, EMS, and rescue services, and 4) US VI Bureau of Information Technology. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 11 A “storm shelter” meets the requirements of International Code Council (ICC) 500. A “safe room” meets the requirements of ICC 500 and the more stringent FEMA Funding Criteria for near-absolute protection. A safe room is an interior room, a space within a building, designed and constructed to provide near-absolute life-safety protection for its occupants from extreme-wind events such as tornadoes and hurricanes. Criteria for FEMA safe rooms, “FEMA Funding Criteria” must be met when FEMA funds are used to construct or install a safe room. A FEMA Safe Room is not intended for use following a high-wind event for people requiring temporary shelter as community recovery efforts begin. The existing site features will be demolished. Demolition includes removal and proper disposal of the multi-story buildings, tennis courts, asphalt pavement, concrete stairs and retaining wall, chain link fence, electrical utilities, and sanitary sewer systems and structures. New site features include mechanical yards, service entrance, sanitary sewer lift station, site retaining walls, stormwater pond, chain link fence w/barbed wire, a rolling gate at the site entrance, site lighting, and parking for 135 vehicles including ADA stalls. Reference attached drawings, C1.00. New utilities include potable water connection to WAPA, sanitary sewer lift station with connection to closest WMA sanitary sewer main, reuse water cistern and pump station, transformer (WAPA), underground power conduits (WAPA), telecommunications conduits and connections to WAPA. Space on the site has been allocated for future expansion including buildings, communications equipment, and future overflow parking. Enclosed parking areas are not part of scope of work for this project. Emergency vehicle parking contingency is planned for in overflow parking areas. The existing trees will be protected and will remain.

The SWPP prescribes controls and procedures to minimize dust. Sequence and estimated dates of construction activities to be determined at time of award of general contractor. The Owner’s representative will be on site for QC/Contract Management. a. Site Work/Provisions to Limit Soil Disturbance All site work and provisions to limit soil disturbance will take place in accordance with the VITEMA Saferoom & Wind Retrofit Stormwater Pollution Prevention Plan (attached), TPDES VI Construction General Permit and Notice of Intent (NOI) for Stormwater Discharges. Location and silt fence details including tree protection details can be found on the Erosion Control and Demolition Plan, C0.90 and the Civil details sheets C4.00 and C4.02. Demolition The existing tennis courts, cistern walls, and foundations contain asbestos and will require remediation and proper disposal. A Hazard Materials Test was conducted and the final report was approved by Environmental Protection. Environmental Concepts Inc., a local approved mitigation firm based in the US Virgin Islands will lead the removal and disposal process during demolition. As part of demolition permitting, the General Contractor will be required to submit an abatement plan to DPNR for approval. All local and federal removal and disposal methods and regulations will need to be adhered to. The estimated demo timeframe will be provided when permit is obtained and general contractor selected. The demolition strategy and expectations shall be outlined and included in the demolition permit submittal and coordinated between the owner, general contractor, and authority having jurisdiction. To control dust, a watering truck or hose from an available water source will drive over exposed areas and wet down soil as needed. The truck will have a 3,000 to 5,000 gallon capacity and the exposed soil will be either hand or machine watered. Vehicle wash down will occur within the area of the site being protected by the perimeter silt fence. There are also other dust control methods for demo and construction the General Contractor could consider and employ if deemed suitable and effective. The GC will submit proposed methods to DPNR to obtain permit. Approved methods will be enforced by DPNR, and VITEMA’s on-site owner’s representative will also ensure agreed upon measures are implemented.

FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 15 To minimize sediment track-out, gravel entrances will be installed at the intersection of the proposed road as shown on Sheet C0.90. the pad will be at least 30 feet wide and 50 feet long and flared out where the gravel meets the existing pavement. The General Contractor will be responsible for maintenance and inspection of the gravel driveway and location and maintenance of equipment staging yards. b. Method of Construction Cast-in-place concrete structure Structure and exterior building components designed to meet/exceed ICC500/P361 wind/pressure and seismic criteria requirements. c. Self-sufficient Systems – Water, Power The safe room program is contained in the north wing of the facility on all four floors. The building can accommodate 200 essential personnel required for emergency and disaster response within the US Virgin Islands. The total safe room usable area is 4,665 square feet. This space includes sleeping areas (bunk rooms), water closets and lavatories, shower and locker rooms, and a kitchen. Stormwater SWP This project will not discharge stormwater to a Municipal Separate Storm Sewer System (MS4). No discharge water from dewatering operations will occur during construction and no chemical treatment of soils or stormwater. Pollutant generating activities include grading, concrete wash out, and transportation and therefore possible pollutants include sediment, cement, and fuel or oil. Authorized non-stormwater discharges include landscape irrigation, water used to wash vehicles and equipment, water used to control dust, potable water including uncontaminated water line flushings, external building washdown, pavement wash waters, and uncontaminated air conditioning or compressor condensate. The stormwater run-off will be directed with grading towards the proposed stormwater structures that will discharge to the proposed pond. The pond footprint and depth are designed to provide sufficient water quality to meet the project water quality requirements. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 16 The volume of the pond will be controlled by a weir. When the volume of the pond reaches the elevation of the weir, water will slowly be discharged through the control structure to an off-site connection point. Basin size: 4.58 acres Location: Project extents Maintenance: will require an operations and Maintenance plan by the Owner Method to reduce flood water: Stormwater system and pond Potable Water – Cisterns The site will be served by both potable water via a site connection to the WAPA public water system and a cistern. The cistern will be located at the basement level of the north wing. The cistern, 28 x 35 feet with an 11-foot water column, and an 80,000-gallon capacity, is divided into cells with walls that allow for part of the cistern to be emptied and cleaned while the remaining cells stay in operation. A 2 x 2-foot access panel will be located on the top of each cell. Of the 80,000 gallons, 22,500 gallons is Fire reserve. Potable water will supplement cistern water reserves. Generator Two (2) diesel emergency generators will be located on site within the mechanical building. Two (2) 10,000 gallon above ground fuel oil storage tanks will be located in the outside mechanical yard adjacent to the mechanical building. A transformer will also be located adjacent to the fuel tanks. Each generator is currently sized at 450 kw capacity. Secondary containment including double wall tanks can be considered. The intent would be to bring fuel trucks to replenish fuel as needed. All required licenses and permits associated with generator installation will be obtained. WAPA is planning a new underground site electrical service which will be extended to the building.

Renewables and Sustainability Currently no funding is available for renewables including solar or back-up alternative energy, including EV charging stations. The master plan identified a potential solar array at the overflow parking area for easy adaptation as funding is available. At this time there are no provisions for green building practice such as green or bioswales, or pervious pavement. VITEMA and SLA acknowledge the challenges of the landfills in the territory and importance of minimizing impacts on them wherever possible. Feasibility of recycling materials during the demolition of buildings is ultimately to the discretion of the general contractor, in determining what materials can and cannot be removed in a manner that allows them to be reused or repurposed. The demolition technical specifications and requirements for this project will be composed to incentivize the general contractor to reused or repurpose materials generated from demolition to the maximum extent possible and suggest opportunities that the design team sees for doing so. Some of these opportunities could include: On site crushing equipment to break down concrete for suitable use as sub base under paving; Recycling processing for copper wiring; Recycling processing for reinforcing steel. e. Provisions to Limit Community Impacts The existing land use adjacent to the new VITEMA EOC is comprised of multi-family and single family residential, religious and institutional, and open space and vacant land. The views from the proposed exterior building will be on existing residential neighborhoods and the multi-family residential condominium complex, Questa Verde. See Attachment H. A model of the views from Questa Verde on the new VITEMA facility is shown in Attachment H. The viewshed photos were presented at the Public Hearing for the re-zoning of the property on October 17, 2022. The property was rezoned from residential to Public on April 25, 2023.

Regulatory Framework This document provides the US Virgin Islands with VITEMA’s consistency determination, data, and information required under the Coastal Zone Management Act (CZMA) Section 307 of 1972 and 15 CFR Part 930, sub-part D, for the VITEMA EOC damaged by recent Hurricanes Maria and Irma. The existing buildings also had damage from other past hazard events dating back to 1995. In accordance with the CZMA, VITEMA is demonstrating consistency with the US Virgin Islands Policies (USVI) of the most recent Virgin Islands Coastal Zone Management Act of 1978, 12 V.I.C § 901. VITEMA is requesting the US VI Department of Planning and Natural Resources’ (DPNR) acknowledgement and concurrence with this consistency determination. b. Project Introduction The existing VITEMA EOC is located on the island of St. Croix, 102-B & 102-C Hermon Hill, Latitude 17.732643, Longitude -64.714632. The site is not located in the Tier 1 coastal zone. The buildings were severely damaged during Hurricane Maria. The FEMA current scope of work is to demolish the existing damaged buildings, last occupied in 2010, and remaining site structures, and construct a new four-story Emergency Operations Center (EOC) and Safe Room within the existing building footprint. The facility will serve as the main offices for VITEMA, the Bureau of Information Technology (BIT), and the 911 Emergency Call Center (ECC). Ground disturbance will include demolition and environmental remediation of existing site features (tennis courts, parking lots) to make way for new surface parking, drainage, water, and wastewater infrastructure. The building and site will meet the Architectural Barriers Act Accessibility Standard (ABAAS). The design will be cost, energy, and space efficient, building on the footprint of the existing buildings, and provide the US Virgin Islands with a self-sufficient, resilient, and state-of-the art communications and emergency response operations center. The new building will operate with on-site water collection systems, emergency generators, and connect to public water, sewer, and power. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 19 c. Coastal Zone Policies: The following eleven policies are set forth in the Virgin Islands Code Title Twelve Conservation, Chapter 21 § 903 (b). POLICY (1) protect, maintain, preserve and, where feasible, enhance and restore, the overall quality of the environment in the coastal zone, the natural and man-made resources therein, and the scenic and historic resources of the coastal zone for the benefit of residents of and visitors of the United States Virgin Islands; The project site is not located in the Tier 1 coastal zone. However, the proposed construction work will be conducted within the regulatory framework of all required, applicable permits. Once constructed, site operations will be carried out with minimal impact to the environment and in conformance with best management practices especially with respect to stormwater runoff, water reuse, and renewable energy. POLICY (2) promote economic development and growth in the coastal zone and consider the need for development of greater than territorial concern by managing: (1) the impacts of human activity and (2) the use and development of renewable and nonrenewable resources so as to maintain and enhance the long-term productivity of the coastal environment; The project site is located outside the Tier 1 coastal zone allowing the most environmentally sensitive land there to be preserved and for growth to be directed where appropriate. The VITEMA project relates to economic development through the facility offering of an improved emergency preparedness and management capabilities. Site operations will be regulated to minimize human impacts. POLICY (3) assure priority for coastal-dependent development over other development in the coastal zone by reserving areas suitable for commercial uses including hotels and related facilities, industrial uses including port and marine facilities, and recreation uses; The project is centrally located on the island, in Estate Hermon Hill, situated away from coastal hazards. The buildings are located on an elevated portion of the site outside mapped flood FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 20 hazards. However, to maintain daily operations, the site relies on commercial and industrial facilities on the coast for shipments of supplies and fuel. Although the site is somewhat self- sufficient, it relies on coastal resources to operate. Operational protocols will be in place, in conformance with permits, for fuel supplies and storage, and solid waste management. POLICY (4) assure the orderly, balanced utilization and conservation of the resources of the coastal zone, taking into account the social and economic needs of the residents of the United States Virgin Islands; Support facilities required for the daily operation of the site, such as potable water collection, stormwater and sanitary sewer systems, water reuse, and energy systems, are designed with the island’s natural and manmade resource capacity in mind. Water and energy will be primarily obtained from St. Croix’s potable water and energy grid. Stormwater generated on site will be discharged into a stormwater pond and the surrounding natural environment taking into account its ultimate fate—to either groundwater or surface water. POLICY (5) preserve, protect and maintain the trust lands and other submerged and filled lands of the United States Virgin Islands so as to promote the general welfare of the people of the United States Virgin Islands; The VITEMA EOC and Safe Room and supporting facilities will be built on the footprint of the existing facility. Proposed land disturbance activities will be reviewed, regulated, and conducted in accordance with the major land development application and permit and the SWPP. No work is proposed on trust, or submerged and filled lands. POLICY (6) preserve what has been a tradition and protect what has become a right of the public by insuring that the public, individually and collectively, has and shall continue to have the right to use and enjoy the shorelines and to maximize public access to and along the shorelines consistent with constitutionally-protected rights of private property owners; FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 21 The VITEMA EOC and Safe Room and supporting facilities will be built on the existing site of the EOC last used in 2010, located in Estate Hermon Hill, Parcel 102-A. The site is not located within the Tier 1 coastal zone. POLICY (7) promote and provide affordable and diverse public recreational opportunities in the coastal zone for all residents of the United States Virgin Islands through acquisition, development and restoration of areas consistent with sound resource conservation principles; The project site will utilize an existing facility located in Estate Hermon Hill therefore leaving existing and future coastal sites for public recreation and conservation initiatives. POLICY (8) conserve ecologically significant resource areas for their contribution to marine productivity and value as wildlife habitats, and preserve the function and integrity of reefs, marine meadows, salt ponds, mangroves and other significant natural areas; In accordance with the Record of Environmental Consideration (REC) the project site does not contain threatened or endangered species or critical habitats, is not on or connected to a Coastal Barriers Resource System Unit or otherwise protected area, is not located in or near essential fish habitat, not located along or affect wild and scenic rivers, is outside a floodplain, and outside wetlands. The project is located within a flyway zone but does not have potential to take migratory birds. No ESAs or Boa habitat recognized. POLICY (9) maintain or increase coastal water quality through control of erosion, sedimentation, runoff, siltation and sewage discharge; Requirements are in place during construction and when the site is occupied and fully operational to protect water quality. During construction work in accordance with the SWPP under the TPDES Construction General permit will minimize erosion, sedimentation, and runoff and minimize the risk of spills and discharge of fuel, fertilizers, herbicides, and other construction materials through pollution prevention measures. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 22 Fuel storage and deliveries will be conducted and in conformance with the Terminal Facilities license. POLICY (10) consolidate the existing regulatory controls applicable to uses of land and water in the coastal zone into a single unified process consistent with the provisions of this chapter, and coordinate therewith the various regulatory requirements of the United States Government; This project is funded under the FEMA, Hazard Mitigation Grant Program, uses Federal dollars, and therefore requires compliance with the Coastal Zone Management Act and is subject to a Federal Consistency Determination. Along with this Federal Consistency Determination administered by the US Virgin Islands DPNR, Coastal Zone Management, VITEMA will construct and operate the new facilities in accordance with the Federal Clean Water Act, Clean Air Act, National Historic Preservation Act, Coastal Zone Management Act, and the Resource Conservation and Recovery Act, and all US Virgin Islands laws, regulations, and policies consistent with these Federal programs, most notably Virgin Islands Code Title Twelve Conservation, Chapter 21 § 903 (b). POLICY (11) promote public participation in decisions affecting coastal planning conservation and development. VITEMA has reached out to property owners to discuss the project and hear their concerns. A re-zoning application was filed with DPNR, Comprehensive & Coastal Zone Planning in October 2022. The property was rezoned from residential to Public in April 2023, with the passing of Bill No. 35-0021, an Act amending the Official Zoning Map No. SCZ-7 for the island of St. Croix. The Federal Consistency Determination requires a public hearing and comment period. The following permit applications will require public notice and/or a public hearing: Air Minor Permit, TPDES Individual Permit, Major Land Development Permit.

DETAILED PROJECT DESCRIPTION a. Summary of Proposed Activity This FEMA funded project will contain new buildings, surface parking facilities, stormwater detention basin and collection system, potable water system, sanitary sewer lift station, emergency generator, fuel storage facilities, emergency generators, and new underground electrical service. b. Purpose of Project Construct a new Emergency Operations Center that combines the VITEMA offices and the 911 Emergency Call Center in one facility that serves the US Virgin Islands. The new facility will support programs badly needed for federal and local emergency personnel to respond to contemporary disasters. These programmed spaces include safe rooms for emergency response staff to remain housed in near-absolute protection for extended periods of time during extreme wind events. c. Presence/Location of Critical Areas and Possible Trouble Spots Currently, no environmental critical areas are located on the site. However, there is a pre-existing condition of non-point source stormwater runoff that sheet flows to existing off-site residential lots located along the northeast side of Vitema Road. d. Method of Demolition/Land Clearing The Erosion Control and Demolition Plan, C0.90 (attached) provides information on all buildings and structures to be removed. In summary, the following existing buildings and structures will be demolished and debris removed in accordance with the demo permit and construction waste management plan: multi-story buildings, tennis courts, asphalt pavement, chainlink fence, electrical and sanitary systems and structures, concrete stairs, and retaining wall. The existing mahogany trees will remain and be protected during construction. A gravel construction entrance will be constructed. A silt fence will be erected around the perimeter of the project site. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 25 Erosion control measures will be installed prior to demolition or construction. See the SWPP for more details. Asbestos concrete pavement within the existing tennis courts will be demolished and disposed of in accordance with permit regulations and disposal procedures. e. Method of Construction Cast-in-place reinforced concrete structure. Structure and exterior building components designed to meet/exceed ICC500/P361 wind/pressure and seismic criteria requirements. f. Provisions to Limit Site Disturbance There are no waters of the U.S. within 50 feet of the project’s proposed earth disturbances. The SWPP identifies methods that will be employed to minimize steep slope disturbances. The total amount of land disturbance occurring at any one time is 5 acres or less. The project site is not located in an arid, semi-arid, or drought-stricken area and no discharges from the site will enter a sediment- or nutrient-impaired, or Tier 2, Tier 2.5, or Tier 3 water. The stabilization practice employed on site will be vegetative and permanent. Erosion control blankets are to be installed and hydro seeded to promote vegetative growth and vegetation will be maintained throughout construction. g. Sediment Control Methods/Post-construction erosion/sediment control There are no receiving waters within 50 feet of the site’s earth disturbance. During construction, silt fences will be installed downstream of all activities. The grade will be stabilized with erosion control blankets and hydro seed or equal. The same erosion control blankets used on the site will be used to cover stockpiles. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 26 Gravel entrances will be installed at the intersection of the proposed road and Vitema Road. The pad will be at least 30’ wide and 50’ long with a flared-out section where the gravel meets the existing pavement. Authorized stormwater discharges include landscape irrigation, vehicle washwater, dust control, potable waterline flushing, exterior building washdown, pavement washwater, uncontaminated air conditioning/compressor condensate. Exposed soil on dry, windy days will be sprayed wet to minimize any dust particles from becoming airborne particulates. A water truck will be ordered on-site as needed to deliver and spray water. The site is minimally sloped. Geotextile erosion control blankets will be used to provide stabilization for the slopes in the vegetated swale and sediment trap. h. Schedule The schedule for staging and phasing of construction activities will be determined by the General Contractor once under contract. As an estimate, the Demolition phase could take 2 months and Construction 18 months. Inspection Schedule: Every 7 calendar days. Corrective Action: Every 14 calendar days and within 24 hours of either: • A storm event that produces 0.25 inches or more of rain within a 24-hour period (including when there are multiple, smaller storms that alone produce less than 0.25 inches but together produce 0.25 inches or more in 24 hours), or • A storm event that produces 0.25 inches or more of rain within a 24-hour period on the first day of a storm and continues to produce 0.25 inches or more of rain on subsequent days (you conduct an inspection within 24 hours of the first day of the storm and within 24 hours after the last day of the storm that produces 0.25 inches or more of rain (i.e., only two inspections would be required for such a storm event)).

Implementation of Sediment Control Measures The silt fences will be maintained weekly and reinstalled to insure proper installation. Any silt build up will be removed prior to accumulating to one-half of the above ground height of the fence. Track-Out Control 1. The stabilized gravel exit detail is shown on C0.90 Erosion control Plan. The contractor is responsible for maintenance and inspection of the gravel driveway and daily maintenance of off-site streets. Stockpile Control 1, Erosion control blankets. Blankets will be used to cover stockpiles. Stockpiles may be placed on site at various times throughout the construction schedule. Dust Control 1, Watering Truck/Hose. A watering truck or hose from an available water source will drive over exposed areas and wet down soil as needed. The truck will have a 3,000 to 5,000 gallon capacity and the exposed soil will be either hand or machine watered. Geotextile erosion control blankets will cover the entire area of the graded slope. The bottom and side slopes will be seeded and mulched before the blanket is applied. The blanket will be installed by digging a small trench on the upside of the slope and stapling the leading edge of the blanket into the trench. The blanket will be rolled down the slope slowly to maintain soil contact. Erosion control blankets are to be installed per the manufacturer’s instructions and specifications. Gravel entrance/exit detail is being provided on the details sheet C4.02, detail 1. Please refer to sheet C2.00 for inlet locations, pipe sizes, material, and inverts. j. Maintenance of Sediment and Siltation Control Measures Silt fences. Silt build up will be removed prior to accumulating to one-half of the above ground height of the fence. The silt fences will be maintained weekly and reinstalled to insure proper function. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 28 Track-Out Control #1, Stabilized gravel exit. Contractor is responsible for maintenance and inspection of the gravel driveway. The exists will be inspected after storm events or heavy use. The exists will be maintained in a condition that will prevent tracking or flowing of sediment onto access road. If excess sediment has clogged the pad, the exit will be top-dressed with new crushed stone. Where sediment has been tracked-out from the project site onto the surface of off-site streets, other paved areas, and sidewalks, the contractor must remove the deposited sediment by the end of the same work day in which the track-out occurs or by the end of the next work day if track-out occurs on a non-work day. The contractor must remove the track-out by sweeping, shoveling, or vacuuming these surfaces, or by using other similarly effective means of sediment removal. The contractor is prohibited from hosing or sweeping tracked-out sediment into any stormwater conveyance (unless it is connected to a sediment basin, sediment trap, or similarly effective control, storm drain inlet, or surface water.”) Stockpile Control #1. Soil or sediment will not be hosed down or swept into any stormwater conveyance (unless connected to a sediment basin, sediment trap, or similarly effective control, storm drain inlet, or surface water.) Dust Control #1. A truck to be available within 24 hours and the existing water supply will be immediately available. Dust control will occur intermittently. The geotextile erosion control blankets will be inspected weekly and immediately after storm events to determine if any cracks, tears, or breaches have formed in the fabric. If so, repairs will be made immediately. Grass will be monitored. Swales and detention pond will be inspected and maintained weekly during construction to prevent flooding on the site. Before vegetation has been established in the pond, it will be inspected for erosion and accumulation of debris and sediment. Repairs are to be made immediately. k. Project Work Plan To be provided by General Contractor as part of permitting, and to be handled in accordance with SWWP requirements. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 29 ATTACHMENT B. ENVIRONMENTAL IMPACT a. Climate and Weather, Landform, Geology, Soils, Historic Land Use, and Topography The project site has a history of wind and water damage from hazard events, documented to the mid-1990s, including flood events, tropical storms, and hurricanes. The site is situated on top of a large hill, surrounded on the east, south and west sides by single family residential dwellings, single family vacant parcels, and vegetated areas. The tallest building, Queste Verde multi-family residential development, is located approximately 260 feet to the north of the project site, or across the street from the entrance to Vitema Road. A topographic survey prepared in May 2022 by The Green Piece, Engineering & Environment, shows the southern-most existing building to be located at the highest point on the site, approximately 252 feet above mean sea level. The land gradually slopes to the northeast of the site where the lowest portion, approximately 206 feet above mean sea level, lies along the northeastern edge of the property, adjacent to Vitema Road. The closest gut lies approximately 335 feet to the west of the site. The Geotechnical Investigation Report prepared by VITEST Engineers in April 2022 indicates the seasonal high-water table will remain more than 20 feet below the land surface. The Island of St. Croix is subjected to occasional earthquake forces and the property is identified as being in risk category IV with Site Class C. Site soils consist of Cramer-Victory complex (12-20% Slope) - CvD and Cramer-Victory complex (2-12% Slope) CvC. The typical soil profile for the site is 1) topsoil/gravel (fill) and 2) gravel over 3) weathered rock. The undeveloped areas of the site consist of trees and other vegetative matter, and dirt. The project site is considered previously disturbed due to prior site grading, construction, and utility work. Ground disturbing activities have low potential to impact intact archaeological resources. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 30 b. Drainage, Flooding, and Erosion Control Vegetative swales will be used to convey offsite runoff from the area adjacent to the project site. Each swale will be directed towards a mitered end where the water will then leave through the proposed pond outfall structure. A Stormwater Pond will be installed to capture runoff from the project site. The pond will have an outfall structure which overflows down the bank on the downstream side of the hill. The swales and stormwater pond will both remain as permanent structures after construction is complete. c. Existing Drainage Patterns Given the new construction located atop the existing facility footprint, the proposed grading and stormwater layout has been designed such that the existing grading and drainage patterns are relatively the same. Please refer to existing conditions sheet C0.02 for existing contours. d. Proposed Alterations – Drainage Swales will convey runoff to the outfall structure. Runoff will be captured in a stormwater pond which has an outfall structure. e. Project Relationship to Coastal Floodplain The project site is located approximately 1 mile from the nearest coastal shoreline and is therefore not located in a coastal floodplain. f. Stormwater Calculations The site has been evaluated using the following criteria in the mentioned order: • Determine the proposed amount of pervious versus impervious surface area to determine the appropriate water quality treatment to provide. • Determining existing conditions previous and impervious area to obtain the existing peak discharge flow with the aid of the software ICPR. • Determining proposed conditions previous and impervious area to obtain the proposed discharge flow with the aid of the software ICPR. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 31 • The discharge flows are compared to size the detention pond. The pond is controlled by a weir that will restrict the outflow to be less or equal to the preconditions discharge flow. • The secondary system is simulated using the software StormCAD, utilizing the ICPR pond max stage as a tailwater throughout the entire system. • StormCAD is used to determine that the 10-year storm hydraulic grade line (HGL) is 1 foot or more below each individual inlet elevation. The 25-year storm is evaluated to determine that the HGL is under each individual inlet elevation. The 100-year storm is evaluated to determine that the HGL is at a minimum 1 foot below the finish floor elevation (FFE) of the proposed building. For this project, the FFE is substantially higher than the pond highwater elevations. • The proposed building roof will act as a rainwater harvesting measure to further reduce the volume of water that is being discharged to the pond. g. Topsoil Preservation Top soil will be stripped and stored for later use. Erosion control blankets will cover piles. Inspect weekly and immediately after storm events to determine if any cracks, tears, or breaches have formed in the fabric. If so, repairs are to be made immediately. Monitor grass. To avoid soil compaction the contractor will restrict the use of vehicles in the locations for hydro seeding. Flags and tape will indicate areas restricted to vehicles. h. Basin a. Capacity Refer to the Civil utility plan indicating cistern overflow will discharge through a pipe to the storm retention area. The capacity is 0.439 ac-ft. b. Vegetation The pond is to be vegetated with grass. The littoral zone may be vegetated per the Landscape Architectural drawings. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 32 c. Maintenance The primary and secondary stormwater systems will require an Operations and Maintenace plan to be followed by the Owner. i. Guts within 100 feet of site There are no guts within 100 feet of the site. j. Fresh Water Resource There are not freshwater resources on the site other than groundwater which is estimated to have a seasonal high-water table remaining more than 20 feet below the land surface. k. Terrestrial Resources The project site is comprised of previously disturbed ground and undisturbed ground. The site was extensively disturbed during the original building construction, which included site grading to level the hill top location with fill as needed and utility placement. The existing mahogany trees will remain and be protected during construction. l. Wetlands No wetlands are present on the project site. m. Rare and Endangered Species No ESA-listed species and/or designated critical habitat under the jurisdiction of the USFWS or NMFS are not likely to occur in the project site. (U.S. Fish and Wildlife Service’s Information for Planning, and Conservation System (IPaC) accessed on 5/2024). There are no threatened or endangered species or critical habitat listed for this project site.

Air Quality Operational air emissions will be limited to emergency diesel generator use during routine maintenance/testing and when the generators are needed during hazard events. Generators shall meet all emissions control standards for such systems. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 34 ATTACHMENT C. HUMAN AND COMMUNITY IMPACT a. Land and Water Use Plans The existing use of the project site as an Emergency Operations Center—a US VI owned property operated by VITEMA—will resume from a hiatus that began in 2010. Partially due to FEMA funding, the proposed building and structures footprint remains relatively unchanged. Two significant items to note about the use is the addition of a FEMA-specified design for a safe room, and the design requirements to bring the buildings into compliance with structural requirements for wind. These requirements impact how the site functions and therefore the essential systems that serve it, including potable water and wastewater, and of course the energy required to run these systems. Land disturbance will therefore remain within the existing disturbed areas with the exception of the following areas where water and wastewater systems are proposed: 1. Potable Water Cistern, capturing rainwater from building roof systems and filtered for reuse. 2. A new potable WAPA water connection is included in the plans 3. Waste water will be pumped to WMA main A stormwater pond, one component of the newly designed stormwater management system, will receive directed stormwater collected from the building roof drains (cistern overflow), paved parking areas, other paved areas including walkways, driveways, and loading zones. i. Access Road The access road will be paved and a stop sign and bar will be located on the access road at the intersection with Vitema Road. ii. Parking Three new paved parking lots are proposed and, with the driveways, will expand slightly beyond the existing improved areas—one in the footprint of the existing asphalt parking area and the other two in the footprint of the existing concrete tennis FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 35 courts. Emergency Overflow parking is noted on the site plan, but will not be paved. Surface parking includes spaces for ADA and RV stalls. The number of parking stalls proposed, including overflow, is 202. iii. Landscaping Existing mahogany trees have been identified and will not be removed but protected during construction. These trees will remain as part of the landscape when the facility is fully operational. Current FEMA funding does include landscaping. b. Visual Impacts Lighting – Site and Exterior Building Site and Exterior Building lighting will be limited to providing the minimum required lighting levels required by lifesafety code. Fixture types will be lensed, and shielded to direct light toward only the areas requiring light, and minimizing any light pollution into the air and offsite to the fullest extent possible. A site lighting plan and fixture specification will be reviewed during permitting, to confirm all codes are being met. c. Public Services and Utilities i. Public Access – To site and buildings The site protocol for security purposes, due to the nature of the operations, is for limited and controlled public access at all times, even during hazard events via gates at each entry point. An 8-ft high chain link fence w/barbed wire will be installed around the perimeter of the site. Access will be controlled with a rolling gate. ii. Sewage Disposal A sanitary sewer system will be located on the project site and will consist of sanitary sewer gravity pipes directly discharging to a lift station. The lift station will pump the flow through a force main to an off-site existing manhole that makes it FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 36 way to an off-site wastewater treatment plant operated by the Waste Management Authority. a) Location The proposed lift station will be located east of the proposed building. The existing off-site discharge manhole is located north of the project site. Please refer to utilities sheet C3.00 and C3.01 for pipe size, pipe material, and routing. b) Capacity Requirements The demand utilized for the lift station design is 64,800 GPD. c) Please refer to utilities sheet C3.00 and C3.01 for pipe size, pipe material, and routing. There is a bit of storage within the proposed lift station prior to the pump being automatically turned on to discharge. iii. Cisterns/Roof Top Collection See previous sections of narrative iv. Public Water A 2-inch public water connection will supplement the cistern system. A new 2-inch potable water pipe will connect off-site to the existing WAPA service. v. Power The site will operate on new underground electrical service provided by WAPA. A transformer will also be provided by WAPA and located on concrete pavement adjacent to the Loading Zone. An underground utility duct bank will run to the transformer from the utility meter and switch gear to be located on the perimeter of the site. See previous sections of narrative FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 37 vi. Fuel Storage Two 10,000 gallon each diesel fuel aboveground storage tanks will be located outside adjacent to the utility building. Fueling, fuel transport, and storage operations will be regulated by a Terminal Facility license. See previous sections of narrative vii. Trash Disposal The proposed site plan includes two dumpster locations. A vehicle tracking model has been developed making sure the location of the dumpsters is accessible to the dumpster truck. Deliveries are proposed to occur on the north side of the building. The vehicle tracking will allow for vehicles to park in the area to unload as necessary. viii. Deliveries Deliveries to this facility will be limited to those needed for a basic office use in normal operations. During emergency events, supplies for sustaining staff for longer periods of time may be necessary. d. Social Impact The existing EOC facilities have been vacant since 2010. The proposed building construction and site improvements will eliminate vacant buildings and abandoned facilities on the site. The new VITEMA EOC, a public facility intended to benefit the US Virgin Islands communities, will provide emergency response personnel the facility to collaborate and coordinate resources in order to respond and serve the public during extreme hazard events. The site will provide a work environment for better comprehensive all-hazards planning and prediction and will support programs badly needed for Federal and local emergency personnel to respond to contemporary disasters, and improve post-disaster response. This includes Caribbean territorial collaboration and data sharing. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 38 The project site has capacity for future expansion of facilities to accommodate Territorial Agency or Federal needs, if the opportunity arises. e. Economic Impact The Federal funds requested for this project FEMA-4340-DR-VI is $22,509,962. Currently, both the VITEMA Main office (at 2164 King Cross Street in Christiansted) and the 911 ECC are in separate locations, leasing space in existing buildings. In 2018 the annual rental costs for both locations totaled approximately $256,000.00. Existing office conditions— for both daily operations and recovery efforts related to catastrophic disaster Irma and Maria—are no longer sufficient and hinder staff in responding to public needs. The leased space is not sufficiently designed or built to serve as safe room for key disaster staff housing during a future disaster event. It is anticipated that there will be savings to the VI Government in rental and utility fees with the retrofit of a hardened and updated EOC as well as the immense value of continuity of government and emergency response activities during and after a disaster. In addition, the retrofit location has direct line of site to all four radio towers which is critical for BIT operations to ensure less down time while also improving connectivity and communications. f. Historical/Archaeological Resource Impact The project’s ground disturbing activities have low potential to impact intact archaeological resources per the December 2018 FEMA Section 106 consultation letter. FEMA, with VISHPO concurrence, determined that the project undertaking will result in No Historic Properties Affected conditioned on the staging of equipment on hardened surfaces and/or previously disturbed areas. In accordance with the SWPP prepared May 2024, installation of subsurface earth- disturbing stormwater controls on the project site will not have an effect on historic properties. The following stormwater controls require subsurface earth disturbance: catch basin, pond, constructed site drainage feature, and culvert. FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 39 Measured drawings and measured photos of existing buildings and structures will be provided to the VI SHPO. These documents will provide a record of the previous and existing conditions on the site prior to demolition. SHPO will be notified during earth disturbance during removal of tennis courts and installation of cisterns if resources are found. g. Recreational Use No public recreational use is proposed. The sidewalks are provided for directed pedestrian traffic to and from the buildings and parking areas. h. Accidental Spills SWPP – Spill Prevention and Response Expected materials on the project site with the potential to require spill containment include vehicle fluids (oil, gasoline, diesel, hydraulic fluid), and human wastes (contained in “Port-O-Potty” type facilities). The Contractor will follow standard procedures when handling such materials. Should a spill occur, the Contractor will immediately over excavate the soils around the spill and dispose of the contaminated soils in an approved facility. Vehicles will be fueled off site. In some cases, small amounts of fuel in approved five-gallon containers will be stored on-site for small equipment re-fueling. Vehicle washdown will take place in an area protected by the silt fence. Emergency Response Plan - Pollution Prevention Practice Adequate supplies will be available at all times to handle spills, leaks, and disposal of used liquids. Storage of soaps, detergents, and solvents will prevent contact with rainwater and/or discharge from the stored area. There will be routine visual inspections of the area to ensure integrity of cover is maintained. Diesel fuel, oil, hydraulic fluids, other petroleum products, and other chemicals will be stored in water-tight containers, and covered, other means to prevent pollutant discharge, FEDERAL CONSISTENCY DETERMINATION SUBMITTAL PACKAGE US VIRGIN ISLANDS VITEMA HERMON HILL WIND RETROFIT AND SAFEROOM P a g e | 40 or stored in secondary containment. Spills will be cleaned up immediately using dry clean- up methods and used materials disposed of properly. The source of the spill will be eliminated to prevent on-going or further discharge. Silt fences and brush berms will be inspected as grading progresses and silt removed if built- up beyond one-third the height of the fence. The SWPP (Attachment) provides detail regarding pollution prevention controls for the storage, handling, and disposal of building products, materials, and wastes, Section 5.5. Wash water from stucco, paint, concrete, oils, curing compounds, and other construction materials will be directed into a leak-proof container or pit. Liquid wastes will be disposed of in accordance with applicable requirements as specified in the SWPP Part 2.3.3.3 Fertilizers will be applied at the appropriate time of year during maximum vegetation growth and not before heavy rains, and consistent with manufacturer’s specifications. Potential Adverse Effects (unavoidable) During construction, including demolition, all noise, dust, construction traffic, and stormwater controls will be in place to minimize impacts to the surrounding residents and natural environment. When operational, the site will be maintained to minimize any adverse impacts on the surrounding neighborhood, including grounds and stormwater detention pond. Deliveries to the site will be carried out in compliance with all permits and licenses, and within facility operation procedures to minimize impacts on the residents and environment.

Interpretation and use of test results are the responsibility of the client. This report relates only to the samples reported above, and may not be reproduced, except in full, without written approval by EMSL. EMSL bears no responsibility for sample collection activities or analytical method limitations . The report reflects the samples as received. Results are generated from the field sampling data (sampling volumes and areas, locations, etc.) provided by the client on the Chain of Custody. Samples are within quality control criteria and met method specifications unless otherwise noted. The above analyses were performed in general compliance with Appendix E to Subpart E of 40 CFR (previously EPA 600/M4-82-020 “Interim Method”) but augmented with procedures outlined in the 1993 (”final”) version of the method. This report must not be used by the client to claim product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government. Non-friable organically bound materials present a problem matrix and therefore EMSL recommends gravimetric reduction prior to analysis . Unless requested by the client, building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample.

EPA created this SWPPP Template to help you develop a SWPPP that is compliant with the minimum requirements of Part 7 of EPA’s 2022 Construction General Permit (“2022 CGP”), and is customizable to your specific project and site. Instructions for Using the SWPPP Template Each section of the SWPPP Template includes instructions and space for your project and site information. Read the instructions for each section before you complete that section. Specific instructions on what information to include is indicated in each text field in blue text. Click on the blue text and the instructions will disappear once you start typing. The SWPPP Template is an editable document file so that you can easily add tables and additional text and delete unneeded or non-applicable fields. Note that some sections may require only a brief description while others may require several pages of explanation. The following tips for using this template will help ensure that you meet the minimum permit requirements: • Read the 2022 CGP thoroughly before you begin preparation of your SWPPP to ensure that you have a working understanding of the permit’s underlying requirements. You will also need to consult Part 9 of the permit to determine if your State or Tribe has included additional requirements that affect you. • Complete the SWPPP prior to submitting your NOI for permit coverage. This is required in Parts 1.4 and 7.1. • If you prepared a SWPPP under a previous version of EPA’s CGP, you must update your SWPPP to ensure that the 2022 CGP requirements are addressed prior to submitting your NOI. • If there is more than one construction operator for your project, consider coordinating development of your SWPPP with the other operators. • Once EPA has provided your site with coverage under the CGP, include your NOI, your authorization email, and a copy of the CGP as attachments to the SWPPP. See Appendices B and C of the SWPPP Template. While EPA has made every effort to ensure the accuracy of all instructions contained in the SWPPP Template, it is the permit, not the template, that determines the actual obligations of regulated construction stormwater discharges. In the event of a conflict between the SWPPP Template and any corresponding provision of the 2022 CGP, you must abide by the requirements in the permit. EPA welcomes comments on the SWPPP Template at any time and will consider those comments in any future revision of this document. You may contact EPA for CGP-related inquiries at cgp@epa.gov.

The proposed project will include the demolition of the existing buildings and the construction of a new four-story building with parking and driveways and a stormwater system. Based upon the findings of the investigation, we believe that the site can be made suitable for the support of the facility. The attached report provides details on the subsurface conditions, evaluation of the site suitability and recommendations for foundation support of the building. We appreciate the opportunity to provide our services on this project and trust that the data and recommendations are clear and understandable. Should there be any questions on the report content or if we can be of further assistance, please call. Very truly yours, VITEST Engineers Improving the Quality of Island Life Donald S. Law Donald S. Law, P.E., MBA President VI Registration No. 1088E Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services Introduction VITEST Engineers has completed a subsurface soil investigation at the location of the VITEMA Emergency Operations Center in Estate Herman Hill on St Croix. This facility will be renovated to meet current needs and design code. This report presents the scope of work performed and the findings of the investigation. We also present our evaluation of the site conditions and recommendations for the foundation design of the proposed structure. Project Description The existing facility is located in Estate Herman Hill. The two buildings have a plan area of approximately 6000 square feet and are located on an elevated area on the property. The approximate elevations of the floor slabs are +246 and +255 feet MSL and the terrain slopes down to approximately +230 Feet MSL at a rate of 3H:1V. The lower area of the site ranges from +230 to +210 feet MSL. The existing buildings will be demolished and replaced with a new structure. The new facility will occupy the footprint of the existing building and will be 4 stories high. The building will include a 911 call center, EOC and VITEMA operations, a 9,968 square feet safe room and 1,420 square feet corridor. There will also be a subfloor area of 2492 sf, which will contain a cistern, MEP support facilities and storage of supplies and equipment required for EOC activities. The preliminary structural design reveals that the building loads will be concentrated on the perimeter footings. There will be no interior loaded footings. The wall loads will range from 14.5 kips/ft to 35 kips/foot. As a result, the foundation soils will be moderately to heavily loaded. Purpose and Scope The purpose of performing this investigation was to explore the subsurface soil and ground water table conditions beneath the site to evaluate the suitability of the subsurface conditions for the support of the proposed buildings and to develop geotechnical engineering recommendations for the design of foundations and site development. In order to accomplish this task, we drilled and sampled six (6) Standard Penetration Test (SPT) boring to a depth of 25 feet below the prevailing grade adjacent to the existing building. The approximate location of the boring is identified on the Location Plan on Sheet 1. The soils encountered in Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services the boring is presented in the form of Soil Profiles on Sheet 2. Samples were obtained from the borings and returned to our laboratory on St Croix for classification by a geotechnical engineer. Additional borings were conducted in the lower elevations of the site where the stormwater system may be located. The boring was advanced to 50 feet deep. Infiltration rates were measured in these boreholes. The information obtained during our field investigations and laboratory analyses was used to develop recommendations for the design of the proposed foundation systems and stormwater system. Subsurface Exploration Drilling Methods - The Standard Penetration Test borings were sampled in general accordance with the procedures of ASTM D-1586 using the open-hole rotary drilling method. The borehole advancement was achieved using 3-1/4 inch diameter hollow stem augers with a rock cutting bit. Soil samples and corresponding SPT penetration resistance (N-values) were obtained throughout the profile using a split- barrel sampler driven by a 140-pound hammer, falling 30 inches. The soil samples recovered from the borings were visually examined in the field with representative samples sealed in airtight containers and transported to our laboratory. Laboratory Inspection and Testing The soil samples were classified in accordance with the Unified Soil Classification System (USCS), ASTM D-2288. The laboratory testing included the determination of the natural moisture content in accordance with ASTM D-2216 and the percent passing the No 200 sieve ASTM D-1140. The results and the classification of the soils samples are indicated in the soil profiles in Sheet 1 attached to the report. The soil descriptions and the symbols used in the USCS system are shown on the Legend on Sheet 2. Evaluation of Subsurface Conditions USDA SCS Soil Survey – The soils in the vicinity of estate Herman Hill were mapped by the USDA Soil Conservation Service and published in the Natural Resources Conservation Service (NRCS) Reports. This survey reports that the soil type across the property is Cramer-Victory Complex (12-20% slope) n(CvD). A brief description of these soils is presented below. Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services Cramer-Victory Complex (CvD): This component is on summits and side slopes of volcanic hills and mountains. The Cramer profile is comprised of dark reddish-brown gravelly clay followed by weathered and unweathered igneous bedrock in the upper 60 inches. The Victory profile has dark yellowish brown, yellowish brown, and pale brown very gravelly loam in the upper 33 inches, followed by weathered and unweathered igneous bedrock to 60 inches. The natural drainage class is well drained. The permeability is moderately slow. The depth to seasonal high water table is more than 6 feet. Shrink-swell potential is high, and the soil is very stony. It is in Hydrologic Soil Group C. Soil Stratigraphy - The near surface material is a brown to light brown silty gravel with roots in the upper 12 to 18 inches. At two of the locations (TB-1 & TB-5) the surface material is asphalt. The topsoil is underlain by a light brown silty gravel to a depth of 7 to 9 feet. The underlying material is weathered rock to the termination depth of 25 to 50 feet. In TB-1, TB-5 and TB -6, the rock layer began at about 1 to 3 feet below the existing grade. A more detailed description of the soils encountered is presented on Sheet 2. Please note that although the boring logs indicate distinct strata breaks, the actual transition between the soil layers may be gradual. The SPT below counts (N-values) were recorded during drilling. These values provide a measure of the relative density of the subsurface soils. The N-values range from 7 to 77 blows per foot in the upper 5 to 9 feet. Below this depth the N-values become 50 blows for less than 6 inches of penetration. The blowcounts are presented adjacent to the soil profiles on Sheet 2. In the upper 5 to 7 feet of the profile, the soils are in a medium dense to dense conditions. The underlying soils are in a very dense condition throughout the depth of exploration. Groundwater Conditions - The ground water table was not encountered in the boreholes at the time of the drilling. The water table elevation is influenced by on-site soils, nearby drainage features, rainfall conditions, relief points, site improvements, etc. The groundwater table will typically attain its highest level near the end of the rainy season. Based upon the soil types encountered, the antecedent rainfall and the measured water levels, we anticipate that the seasonal high-water table (SHWT) will remain more than 20 feet below the land surface. Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services Engineering Evaluations and Recommendations General Discussion – The soil profile across the site disclosed a medium dense to dense condition within the depth of foundations. The remainder of the profiles is weathered rock that is very dense. With the exception of the topsoil, there was no organic material encountered within the borings. Adequate foundation soil preparation and design will be required to support the proposed structure. Following adequate soil preparation, the proposed building may be supported on a shallow foundation. Recommendations for site preparation and foundation design are presented in the following subsections. Earthwork Considerations Clearing and Grubbing - The construction area should be cleared to remove all existing buildings, pavement, vegetation, rocks, construction debris, and other unsuitable materials buried under the ground surface. These operations should be completed to a minimum of 5 feet beyond the building perimeters. The depth of grubbing and stripping should be determined in the field based on visual observations and proper judgement. The spoil generated during these operations should be removed from the site and disposed of as directed by the owner. Site Grading - The final grading plan of the site should allow for positive drainage away from the foundations. During construction, the area should be graded to direct surface runoff away from the structures and temporary excavations. Excavation - Temporary side slopes of excavations may stand near vertical for short periods. Side slopes of excavations to 10 feet should be laid back at 2 Horizontal to 1 Vertical or flatter. Side walls of excavation deeper than 10 feet should be protected by a method designed by a registered engineer. The contractor should follow all recent OSHA safety requirements for excavation. Suitable Fill - All fill required for site grading and backfilling should be comprised of clean, non-plastic gravel-silt-sand mixtures containing less than 20 percent passing the U.S. No. 200 Sieve and meeting the AASHTO requirements for fill. The fill should be free of topsoil, roots, organic material, rocks larger than Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services 2 inches, debris, trash, or other objectionable material that may be compressible, degradable or which cannot be compacted properly. Fill Placement and Compaction - The fill should be placed in relatively level lifts, dried or wetted as needed, and then compacted to a minimum density of 95 percent of the Modified Proctor Maximum dry density (ASTM D-1557) unless otherwise specified. The lifts should not exceed 12 inches in loose thickness if compaction is performed by a heavy vibratory roller and 6 inches if an approved hand-operated compaction plate is used. Vibratory rollers should not be used in a vibratory mode within 75 feet of any existing structures without vibration monitoring. Sufficient earthwork monitoring and a sufficient number of in-place density tests should be performed to evaluate fill placement and compaction operations and to confirm that the required compaction is being achieved Foundation Support Foundation Loading Conditions - The structural data provided indicate that the building loads will be transferred to the soil along strip footings around the perimeter of the buildings. The loads will range from 14.5 to 35 kips per foot. Subgrade Improvement – Based upon the soil conditions encountered in the borings, the excavation for footings may encounter weathered rock. Once the bottom elevations are achieved, no other preparation is needed in this material. In areas where the gravelly silty is encountered. we recommend that this material be compacted and tested to at least 12 inches below the bottom of the footings. Shallow Foundation - Provided that the subgrade is prepared as recommended, the footings may be designed using a net allowable bearing pressure of 4500 pounds per square foot (psf) or less. The minimum embedment depth of these footings should be 2 feet as measured from the bottom of the footing to the lowest adjacent finished grade. Footing width shall not be less than 3 feet. Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services Slab-on-Grade – Floor slabs may be supported directly on compacted subgrade. The slabs should be adequately reinforced and should be placed on a vapor barrier at least 6 mils thick. The vapor barrier should be overlapped and sealed where they are joined. A modulus of subgrade reaction of 300 pounds per cubic inch may be used on designing slabs on the compacted, improved soil. Seismic Considerations - Since the Island of St Croix is subjected to occasional earthquake forces, the building should be designed to account for lateral earthquake forces. Liquefaction of the subgrade soils is a concern for buildings foundations in earthquake zones. Liquefaction is the seismic phenomenon where loose, saturated granular soil behave like a fluid when subject to high intensity ground shaking. However, liquefaction is a concern when the foundation soils are predominantly loose sand deposits with shallow water table. The soils encountered within the depth of the borings are primarily dense weathered rock and is not considered liquefiable soils. The groundwater table at the subject site is expected to remain deeper than 20 feet. As a result, we anticipate that the liquefaction potential is low to nil. The site class was evaluated using the Standard Penetration Test N-Values and the site class definitions of the International Building Code (IBC) and the National Earthquake Hazard Reduction Program (NEHRP). Based upon the consistency of the soil profile and material encountered, we estimate that the site can be categorized as Site Class C The earthquake spectral response of the site was evaluated using the ASCE 7 Hazard Tool. The property is identified as being in risk category IV with Site Class C. The seismic design parameters for the site may be taken as shown on the table below. SEISMIC DESIGN PARAMETERS Site Coefficient Site Amplification Factor Spectral response Design spectral response Ss=0.83 Fa=1.105 SMS=0.92 SDS=0.61 S1=0.27 Fv=1.568 SM1=0.39 SD1=0.26 Peak Ground Acceleration PGA – 0.4 Long-period transition period TL- 12 sec Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services Foundation Settlement – Provided that the foundation is designed and constructed as recommended, we estimate that the maximum static settlement of the structures will be less than 1 inch. Differential Settlement is expected to be ½ inch or less. We anticipate the settlement will be complete soon after the roof loads are applied. Lateral Earth Pressures: The walls of the basement level of the structure will support backfilled soils. These walls and other retaining walls should be designed to support the lateral earth pressures exerted by the compacted soils. The lateral earth pressures are presented as equivalent fluid unit weights in pounds per square foot (psf) per foot of depth (pcf). The backfill soils are assumed to have a moist unit weight of 125 pcf and an internal friction angle of 34 degrees. For the design of rigid walls that are not free to rotate, we recommend that the "at rest" earth pressure be calculated using an equivalent fluid pressure of 55 pounds per cubic foot (pcf) above the water table. Where retaining walls are free to rotate at the top, the "active" earth pressure should be calculated using an equivalent fluid pressure of 35 pcf above the water table. In each of these designs, the equivalent fluid pressures assume free-draining conditions and that a drainage system with an appropriate outfall will be included behind the walls to prevent the build-up of hydrostatic forces. In general, structural loads within a 1:1 (horizontal to vertical) upward projection from the bottom of the proposed basement/retaining wall footing will surcharge the proposed retaining structure. If a uniform surcharge is applied to the top of the walls, this will produce an additional lateral pressure along the wall equal to about 1/3 the vertical contact pressure. Lateral Resistance: Lateral forces applied to footings may be resisted by the passive pressure mobilized on the buried face of the footing and by friction along the base of the footings. The passive pressure produced by compacted backfill can be taken as that equivalent to the pressure exerted by a fluid weighing 445 pcf . A coefficient of friction of 0.42 may be used for calculating the frictional resistance along the base of cast- in-place concrete footings. Additional lateral resistance may be realized by designing the footings with a "key" at the base and mobilizing the passive resistance along the vertical face of the key. The values Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services presented presume that the footings are surrounded by well-compacted, suitable soil with a moist unit weight of approximately 125 pcf and that the footings can withstand small movements on the order of 1/4 inch. A factor of safety of at least 1.5 is also recommended in the design. Uplift Resistance - Uplift resistance for the foundation will be provided by the dead loads applied on the foundation and the weight of the foundation. Additional uplift resistance, if needed, can be realized by increasing the width of the foundation, the embedment depth or by anchoring the foundation. A minimum factor of safety of 1.5 should be used against uplift. Elevator Pits and Cisterns: The elevator pits and cisterns will be embedded in the rock layer encountered. The excavation and replacement procedures recommended earlier in this report will apply to the foundation of these structures. The walls of the elevator pits or cisterns should be waterproofed using industry standards and methods. The elevator pits should also be designed to resist uplift. We recommend that the base slab of the pit be extended beyond the perimeter walls to assist in uplift resistance. The uplift resistance can be calculated as described earlier in this report. Pavement Support General Requirements: The pavement area should be cleared, grubbed, graded as needed to provide positive drainage. The pavement subgrade soils should provide adequate subsurface drainage to protect the pavement over time. The groundwater table is not expected to affect the pavement at this site. The pavement section should not be constructed directly on pumping or yielding soils. The pavement subgrade should be proof-rolled and inspected prior to pavement construction. Any yielding areas should be replaced with compacted fill. The replacement material should meet the requirements as recommended in the Earthwork Activities section of this report. Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services Recommended Pavement Section: Following adequate site preparation, the pavement section may be a flexible, a semi-flexible, or a rigid pavement section. The proposed pavement will be subjected to lightly loaded vehicles. Pavement Subgrade: In order to promote proper drainage for the pavement section, we recommend that there be sufficient granular material with a maximum of 15 percent passing the US no 200 sieve. This material should have a maximum liquid limit of 35 and Plasticity Index less than 12. The California Bearing Ratio (CBR) of the subgrade shall not be less than 20. The subgrade material should be compacted to a minimum of 95 percent of the soils maximum modified proctor value as determined by ASTM D-1557. Flexible Pavement Section. Sub-base Course: The subbase material in the flexible pavement section shall have a minimum strength equivalent to a California Bearing Ratio (CBR) of 30. The material shall have a maximum of 15 percent passing the US No 200 sieve, a liquid limit of not more than 25 and Plasticity of 5 or less. We recommend a minimum thickness of 6 inches, compacted to a minimum of 95 percent of the maximum modified proctor value. The compacted material shall be firm and unyielding. Base Course: An approved aggregate base course is recommended for the pavement. The base material should be compacted to a 98 percent of the maximum modified proctor value and should have a minimum California Bearing Ratio (CBR) of 100. The minimum thickness of the base should be 6 inches. Alternative materials may be used provided that it meets the specifications for base course and that the thickness, strength, and compaction are considered in the pavement design. Surface Course: We recommend a Hot Mix Asphalt for the wearing surface of the pavement. The mix design selected for the HMA should be stable, weather-resistant, wear-resistant, waterproof, and non- slippery. We recommend a minimum thickness of 1-1/2 inches of compacted pavement. We further recommend a minimum of 2 inches of wearing surface along the driveway where the vehicles will be stacked for entering and exiting. The surface smoothness shall have a maximum deviation of 1/4 inch. Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services The minimum thicknesses provided here will result in a Structural Number of 2.7. The actual pavement section should be designed for the actual equivalent 18 kip single axle load anticipated over the life of the pavement. Rigid Pavement Section A rigid pavement section may also be used for this application. The subgrade preparation recommendations above will also apply to this pavement section. The subgrade should be firm and unyielding and well- drained. The Concrete used in a rigid pavement section should have a 28 day strength of 3000 psi. A minimum of 6 inches of concrete is recommended for the normal vehicle access areas. A minimum of eight inches of concrete is recommended for heavy traffic areas. The concrete pavement should be designed with adequate longitudinal and transverse reinforcement and expansion joints. The approach slab of the dumpster areas should be designed to withstand the stopping and turning forces produced by the disposal vehicle. Stormwater Management Facilities. Infiltration Rate. A hollow-stem auger boring (PB-1) was excavated and sampled to a depth of approximately 50 feet in the lower elevation of the site. This boring was used to estimate the infiltration rate of the soils. The soils to 50 feet deep are a silty gravel to about 6 feet, followed by weathered rock to 50 feet. A constant head, uncased hole test was conducted. Once the borehole was filled, the volume of water to maintain a constant head was measured every 6 minutes. The average raw flow rate over the last three consecutive readings is known as the measured stabilized flow rate. To determine the raw measured infiltration rate, the stabilized flow rate is divided by surface area of the borehole. The measured stabilized flow rate and raw measured infiltration rate are provided on the table below. The results do not include any reduction factors for the test procedure, site variability and long-term siltation plugging that are required in order to determine the long-term design infiltration rate. Location Stabilized flow rate Measured infiltration rate PB-1 0.64 gpm 22 inch/hr Geotechnical Investigation Report VITEMA EOC Facility St Croix, Virgin Islands Project No: VTE22-01.1101 VITEST Engineers Civil &geotechnical Engineering Materials Testing&Environmental Services Coefficient of Permeability: A field permeability test was conducted in the general area of the proposed stormwater system. The method used was a cased hole with an uncased extension. The cased interval was 2.5 feet below the land surface. The uncased extension extended to 5 feet below the land surface. The test hole was filled with water and allowed to saturate. After a period of saturation, the time for the level in the casing to fall 3 inches and 6 inches was measured. Using a formula associated with the test configuration, the coefficient of permeability was determined to be 0.06 feet/day (2.1x10-5 cm/sec). Pond Design: The stormwater system can take the form of open dry or wet bottom ponds, exfiltration systems, ditches, swales, or other approved systems. The system selected will be dependent upon the soil and groundwater table conditions, the stormwater runoff, the space available and the DPNR requirements. Based upon the subsurface soils encountered, and the measured permeability, we anticipate that the stormwater system will not percolate the pollution abatement volume or the storm volume with in the required time. As a result, we recommend that a detention system be designed for this project. The detention system should be designed with a control structure equipped with a bleed-down device to recover the pollution abatement volume and a weir to attenuate the storm volume. The outfall from the control structure should not exceed the pre-development discharge rate from the site. An appropriate positive outfall is required. If a positive outfall is not available, the system should be designed to hold the 100 year flood runoff.

April 26, 2023 School Construction, Maintenance and Capital Fund; and making an appropriation of $2,500,000 from the Virgin Islands Education Initiative Fund to the School Construction, Maintenance and Capital Fund and for other related purposes. I have approved Bill No. 35-0053, an Act granting a zoning use variance for Parcel No. 84 Estate Contact, No. 7B, Southside Quarter, St. Thomas Virgin Islands from the R-3 (Residential-Medium Density) zoning designation to allow for offices. I have also approved Bill No. 35-0063, an Act approving the conveyance by the Virgin Islands Port Authority to the University of the Virgin Islands of Tract E, Parcel 72 Estate Lindbergh Bay, 4A Southside Quarter, St. Thomas, Virgin Islands, in exchange for the University of the Virgin Islands’ conveyance to the Virgin Islands Port Authority of Parcel No. 66-5 Estate Lindberg Bay St. Thomas, Virgin Islands and Bill No. 35-0068, an Act authorizing the members of the Board of Medical Examiners to serve temporarily as de facto board members of boards established under title 3 Virgin Islands Code, section 415 if a board does not have enough members to establish a quorum; I have approved Bill No. 35-0072, an Act ratifying the Governor’s approval of Major Coastal Zone Management Permit No. CZT-03-20 (L&W) issued to SVB 155 SPRING LLC, D/B/A Independent Boatyard and Marina, however I have used the authority granted by 1 V.I.C. § 14 to correct a typographical error in acreage. I have approved Bill No. 35-0054, an Act amending title 1 Virgin Islands Code, chapter 7, section 103b, relating to the Centennial Treasures Award, to provide for a single, lumpsum award payment, which also included nongermane amendments, however I have exercised the authority granted to me by Section 9 of the Revised Organic Act of the Virgin Islands of 1954 to strike the following provision. In Sections 5, internal subsection (c), “Ninety days after the approval of the CZM permits for the Randall “Doc” James Racetrack,” was stricken as it seeks to interfere with and modify contractual rights and obligations, which is prohibit by the Contracts Clause in the U.S. Constitution. It perplexes me that the V.I. Legislature would seek to interfere with contractual obligations and safeguards negotiated to protect the Government’s investment. Pursuant to the Amended Franchise Agreement, the Government of the Virgin Islands agreed to grant VIGL Operations LLC (“VIGL”) a sum of money 90 days after the actual development of the project starts on the property. I look forward to that day when this project has advanced sufficiently to cause the Government to disburse the funds agreed to in this Amended Franchise Agreement. Additionally, although I have approved Section 6 of the Bill, the section suspending the provisions of title 32 V.I.C. ch11, subch II, relating to Horse Racing Anti-Doping, I must remind the public that while the law is being suspended here, the Horse Racing Commission of the V.I. has made it clear that they will not sanction any races that do not conform to the Anti-Doping rules for horse racing. I have vetoed Bill No. 35-0023, an Act granting a zoning use variance from the B-2 (Business- Secondary/Neighborhood) zoning designation to Plot Nos. 50-1 and 50-4 Estate Orange Grove, Company Quarter, St. Croix, Virgin Islands to allow for the manufacture of concrete products. It is imperative that we consider the impact that our momentary decisions may have on future generations of Virgin Islanders. The Department of Planning and Natural Resources is actively Letter to Honorable Novelle E. Francis, Senate President Re: Governor’s Actions on Bill Nos. 35-0006, 35-0007, 35-0009, 35-0010, 35-0011, 35-0017, 35-0018, 35-0019, 35-0021, 35-0022, 35-0023, 35-0024, 35-0025, 35-0026, 35-0040, 35-0049, 35-0050, 35-0052, 35-0053, 35-0054, 35-0055, 35-0061, 35-0063, 35-0068, and 35-0072. April 26, 2023 developing a comprehensive land and water use plan to safeguard our home for the future. We must give the professionals at DPNR the discretion to determine what is and is not appropriate use for the preservation of our land. They are the experts in the field tasked with the responsibility of guiding the protection of our Territory. We must allow them to complete the task we have set before them. I have vetoed Bill No. 35-0052, an Act amending Official Zoning Map No. SJZ-3 for the island of St. John to change the zoning designation of Parcel No. 14 Rem Estate Carolina, Coral Bay Quarter, St. John from R-2 (Residential-Low Density-One and Two Family) to B-2 (Business- Secondary/Neighborhood). As with other measures sent to my desk against the recommendations of DPNR, I cannot approve this measure. I look forward to approving a revised Bill which incorporates the conditions DPNR recommended. I have also vetoed Bill No. 35-0055, an Act amending title 17 of the Virgin Islands Code pertaining to the school curriculum in elementary and secondary schools. The language of this section was revised in January of this year by Act 8684 to ensure that VI and Caribbean history are integrated into school curriculum for kindergarten through 12th grade. Bill No. 35-0055 is both unnecessary and cumbersome. Attempting to mandate specific courses for school children would result in altering graduation requirements, increasing the number of teachers needed in an already strained school system, and conflicts with existing policy set by the Board of Education. It is within the purview of the Board and the Department of Education to ensure that the curriculum for school children adequately integrates our history throughout a child’s education, as required by existing law. Finally, I have vetoed Bill No. 35-0061, an Act directing the Virgin Islands Inspector General to conduct an audit of the Virgin Islands Water and Power Authority; making a $250,000 appropriation to conduct the audit; and for other related purposes. Like its predecessor, this Bill would inappropriately infringe on the Inspector General’s independence to select how to best investigate the totality of government. Additionally, the measure is duplicative, as the Inspector General has completed its review of the WAPA-VITOL Fuel Contracting Process and Transactions and submitted the report to the Attorney General of the Virgin Islands and the Office of the U.S. Attorney. As you know, I have requested that the Inspector General review the Legislature’s proposed inquiries and provide a timeline and cost estimate for investigating the outstanding questions. I thank the members of the Thirty-Fifth Legislature for their service on behalf of the People of these U.S. Virgin Islands.
