Indian River County Department of Utility Services 1801 27th Street, Vero. Beach 329603 388 Email: aweragoda0,ircgov.com Subject: Proposal to Indian River County for Due Diligence and Project Review West Regional WWTF Reclaimed Water Storage Dear Mr. Weragoda: Tetra Tech, Inc. (Tetra Tech). is pleased to provide Indian River County with this Scope of Work for services to provide due diligence services to assess a potential property purchase and construction of a reclaimed water storage area on a parcel located immediately t� the south of the West.Regional Waste Water Treatment Facility (WWTF). BACKGROUND Indian River County needs additional storage of reuse water from the West Regional WWTF during.the rainy season When the necessity for reuse water is limited. The West Regional WWTF is sized for a treatment capacity of 6 million gallons.per day (MGD). The plant is currently operating at approximately 2 MGD but can only discharge approximately 0.4 MGD or exceed the load allocations into. the relief canal. The remainder of the :treated water is sent back to the community for reuse: The goal of the proposed reclaimed water storage will be to provide sufficient capacity to store water during the wet season and supply reuse water in .the dry season and achieve a zero discharge to the relief canal. The county has identified an approximately 250 -acre_ parcel immediately to the south.of the West Regional WWTF as a potential site for the reclaimed water storage. It is zoned RS -3 and is a citrus grove. The:County contacted.Tetra Tech to complete due diligence required to assess this, potential project, zoning iand. permitting issues associated with project, geotechnical ,conditions, limitations from Federal Aviation Administration (FAA) or other agencies,.and other business. and environmental risks associated :with the purchase of the proposed parcel.

Suite 204, Cocoa, FL 32922 Tel 321.636.6470 Fax 321.636.6473 www.tetratedi.com Mr. Arjuna Weragoda, P.E March 14, 2019 Page 2 SCOPE OF WORK Task 1— General Property, Land Use, Permitting, and Zoning Review - $6,046 An overall assessment of site suitability based on current State of Florida waste water treatment regulations and other potential limitations will be completed. We will consider the following with our due diligence: Existing permitsor other encumbrances: based on a review of Florida Department of Environmental Protection (DEP) Oculus and St. Johns River Water Management District (SJRWMD) records; Evaluation of surrounding land uses and restrictions provided by those uses (specifically the air strip to the south); Hydrologic survey; Permitted potable wells within a one -mile radius; Proximity to on and off-site water bodies, including wetlands; Proximity to airports; Proximity to power lines; Setbacks; County zoning and determination if rezoning is required; Determination if mining permit is required; Off-site improvement requirements; Summary of applicable permits, permit fees, and potential limitations associated with each permit as well as anticipated timeframe needed to obtain each permit; We assume that traffic impacts and availability of utilities are not an issue for the site. Task 2 — Phase I Environmental Site Assessment (ESA) $4,031 The Phase I ESA_identifies the potential.for existing environmental contamination. from a review of present and historical land uses. The Phase I ESA is a due diligence document to ensure that those undertaking or investing in a project are fully aware of environmental contamination issues. as well as the associated liability. Tetra Tech will complete'ahistorical and regulatory records review ofthe Site and adjacent properties. To facilitate the regulatory records review, a database review report. will be procured from Environmental Data Resources; Inc. (EDR). Historical records to be reviewed include, but are not limited to, Sanborn Maps, city directories, Flood Insurance Rate Maps, water well records, and U.S. Geological Survey 7.5 -minute topographic quads. Tetra Tech will complete the following ESA Field activities at the subject site: • • Reconnaissance ofthe Site and adjoining properties and selected properties 'identified during the database review, where appropriate: per ASTM El 527,13; • Site interviews of key:personnel; TETRA TECH Mr. Arjuna Weragoda, P.E March 14, 2019 Page 3 • Reviews of federal; state, local and tribal (if applicable) records as defined in ASTM E1527-13; • Incorporate All Appropriate Inquiries components which include a review of market value prices for the property adjacent properties and an environmental liens search as defined by E1527.-13; • Identify areas on site that will require analytical sampling assessment:through records search and site visit. Based on the findings of the historical records review andsite reconnaissance, Tetra Tech will prepare an ASTM Phase I ESA Report for the Site. The report will be prepared in accordance to ASTM E1527-13. Task 3 - Ecological Review (Limited) - $3;562 For this task we propose a field and desktop due diligence effort to make an initial assessment on the potential development constraints including wetlands, threatened &:endangered species, and potential mitigation options for impactsto natural resources. The following scope will detail the components included with each of the three fatal flaw review topics provided, including Wetlands Habitat Classification and Quality,. Threatened and Endangered Species habitat evaluation, and Federal Emergency Management Agency's floodzone information. The desktop investigation will include National Wetlands Inventory (NWI) wetlands, U.S. Department of Agriculture -Natural Resources Conservation Service (USDA-NRCS) soils, Florida Land Use, Cover, and Forms Classification System (FLUCFCS) mapping of on-site land Uses, Florida Fish & Wildlife Conservation Commission, (FFWCC) listed species habitats and associated data, U.S. Fish & Wildlife. Service (USFWS) Consultation Areas,and any other applicable publicly available resources with potential to effect. Additionally, Tetra Tech:will provide the development constraints and potential permitting related to threatened and endangered species, for which the Project site may provide suitable habitat Task 4 — Geotechnical Analysis - S28,028 j A geotechnical analysis is required to determine suitability of the 250 -acre property to support the reclaimed water storage. For this evaluation, borings should be focused on the proposed berm area. Since the berm locations have not been designated, we recommend 4 borings along a north -south transect, and 4 borings along an east-west.transect (8 borings total) be completed to.a. depth of approximately 60 feet or to the bedrock, using. standard penetration test: Tetra Tech's geologist will provide drilling oversight and will prepare detailed boring logs of each location. Percolation tests will also be completed on site insix locations. Additional borings and testing should be completed once the conceptual design is better defined. Three Shelby Tube samples will be collected, in addition to approximately 10 bagged samples for geotechnical laboratory testing. Testing will include sieve/gradation, atterberg, hydraulic conductivity, and soil strength. Specific testing will be determined based on samples recovered. Data obtained from the laboratory testing will be used to prepare a preliminary:determination of soil bearing capacity and settlement (using an assumed berm height with 4:1 slopes).: Since the site is an active citrus grove, it is assumed that soil samples will be required to assess the potential for contamination from past site activities. Based on this assumption, surface soil TETRA TECH Mr. Arjuna Weragoda, P.E March .14, 2019 Page 4 samples will be collected from four areas and analyzed for: pesticides, herbicides, and arsenic. If maintenance and/or fuel storage areas or other hazardous materials use or storage are identified, additional sampling and analysis may be required. Task 5 = Stormwater Review.- $8,133 A desktop review of the drainage and flood conditions of the site will be completed to coordinate the potential constructability of the potential reclaimed water storage area We note that the establishment of a flood elevation, if not available:from FEMA, is beyond the scope of this project. We will estimate the floodplain compensation that would be required if the land were to be developed. The following documents will be reviewed as part of this evaluation: ERPs for the property comprising.the 250 -acre parcel,. if available; Topographic survey for the property comprising the 250 -acre parcel, if available; Conservations easements for the property comprising the 250 -acre parcel, if available; Readily available USDA soil information; Readily available USGS topographic information to determine overall drainage patterns; Local stormwater regulations; and Results of geotechnical analysis. Task 6 -.Summary Report - $5,680 A summary report of all findings will be prepared for this due diligence effort, and will include: General Property, Land Use, Permitting, and. Zoning Review; Results of the Phase I. ESA (provided. as a separate Appendix); Results of the Geotechnical Analysis; Results of the Ecological Review: Identification of threatened.and.endangered species: which have potential to inhabit the site and permitting action necessary to mitigate in the event of development of the site; Results, of the desktop mapping analysis; and •_ Other potential development constraints raised during the investigation 'including permitting issues. General summary and conclusion of design and permitting limitations anticipated for the site. Tetra Tech will provide general order of magnitudecosts for the design; permitting and construction of the proposed reclaimed water storage facility. The estimates will be made without detailed engineering data and subsequently will have :a wide accuracy range. Please note that -this level of cost estimating is intended for project'screening, concept evaluation and alternative scheme analysis. TETRA TECH Mr. Arjuna Weragoda, P.E March 14, 2019 Page 5 Task 7 (future scope) — Conceptual Design Based on the assessment competed above, an assumed area available for development will be established, maximum berm height Will also be established, resulting in and assumed maximum reclaimed water storage capacity. Design criteria will be provided by IRC to compete the conceptual design for the reclaimed water storage. Additional scope will be prepared for this task upon completion of the above summary. The conceptual design will also include a probable cost estimate for the design, permitting and construction of the conceptual water storage facility. PROJECT SCHEDULE The approximate duration noted for each task is based on our current understanding and best estimates of time required to perform the basic services and maybe subject to change upon agreement between Indian River County and Tetra Tech.
