Incorporated in 1996, the Village has a population of over 18,000 (based on the 2010 Census) and has a total area of approximately 7.53 square miles. The Village falls within the boundaries of the South Florida Water Management District (SFWMD) C-2 and C-100 Basins. These basins are drained by the C- 2 Canal (Snapper Creek Canal) and the C-100 Canal, both primary SFWMD canals. The C-100 receives discharges from the Village via the C-100A, C-100A Extension Canals (Cutler Drain Canals maintained by SFWMD) and the SW 70th Avenue Canal that it is owned by Miami-Dade to the County but is maintained by the Village of Pinecrest. The Village has adopted a Stormwater Master Plan (SWMP) to serve as a planning-level engineering document to analyze and provide recommendations to address the Village’s flooding issues. The Village has requested a proposal for Stormwater Design Services for Sub-basin U35- S as delineated in the Village’s SWMP. Sub-basin U35-S ranked 4th place in its Flood Protection Severity Score (FPSS). Sub-basin U35-S encompasses approximately 42.4 acres and approximately 3,600 LF of stormwater improvements. The proposed stormwater improvements for Sub-basin U35-S include new exfiltration trenches, solid pipes, catch basins, stormwater manholes, interconnections with the exiting drainage systems and three (3) outfalls to the SW 70th Avenue Canal with corresponding control structures. A Project Area Map depicting the project limits and Conceptual Drainage Plan for Sub-basin U35-S per the Village’s SWMP is presented in Appendix D. DESCRIPTION OF SERVICES At the request of the Village, 300 Engineering Group, L.L.C.

Senior Engineer Principal Engineer Proposal for Geotechnical Engineering Services Village of Pinecrest/Basin U35-S Village of Pinecrest, Florida ■ September 8, 2022 ■ Terracon Proposal No. PH8225098 2 EXHIBIT A - PROJECT UNDERSTANDING Our Scope of Services is based on our understanding of the project as described by 300 Engineering and the expected subsurface conditions as described below. We have not visited the project site to confirm the information provided. Aspects of the project, undefined or assumed, are highlighted as shown below. We request the design team verify all information prior to our initiation of field exploration activities. Site Location and Anticipated Conditions Item Description Parcel Information The project is located along SW 112th Street and SW 72nd Avenue in Village of Pinecrest, Florida. See Site Location Current Ground Cover and Existing Improvements Existing asphalt paved roadway – one way in each direction and green landscape area on both sides of the roadway Existing Topography Relatively flat Site Access We expect the site, and all exploration locations, are accessible with truck mounted drill rig. Planned Construction Item Description Project Description The project consists of drainage improvements along SW 112th Street and SW 72nd Avenue in Village of Pinecrest, Florida. Proposal for Geotechnical Engineering Services Village of Pinecrest/Basin U35-S Village of Pinecrest, Florida ■ September 8, 2022 ■ Terracon Proposal No. PH8225098 3 EXHIBIT B – SCOPE OF SERVICES Field Exploration The field exploration program is based on Terracon’s knowledge of the existing subsurface conditions near the project area. Our proposed field exploration program consists of the following: Number of Borings Planned Boring Depth (feet) 1 Planned Location 4 20 Proposed Borings 4 15 Percolation Tests at the same locations of the borings 1. Below ground surface. Boring Layout and Elevations: We will use handheld GPS equipment to locate borings in the field. Field measurements from existing site features may be utilized. If available, approximate elevations are obtained by interpolation from a site specific, surveyed topographic map. Subsurface Exploration Procedures: We will advance soil borings with a truck-mounted drill rig using drilling mud and casing. Five samples will be obtained in the upper 10 feet of each boring and at intervals of 5 feet thereafter. Soil sampling is typically performed using the split- barrel sampling procedures. In the split barrel sampling procedure, a standard 2-inch outer diameter split barrel sampling spoon is driven into the ground by a 140-pound automatic hammer falling a distance of 30 inches. The number of blows required to advance the sampling spoon the last 12 inches of a normal 18-inch penetration is recorded as the Standard Penetration Test (SPT) resistance value. The SPT resistance values, also referred to as N-values, are indicated on the boring logs at the test depths. The samples will be placed in appropriate containers, taken to our soil laboratory for testing, and classified by a geotechnical engineer. In addition, we will observe and record groundwater levels during drilling and sampling. Our exploration team will prepare field boring logs as part of standard drilling operations including sampling depths, penetration distances, and other relevant sampling information. Field logs include visual classifications of materials encountered during drilling, and our interpretation of subsurface conditions between samples. Percolations Tests: Four (4) Percolation Tests will be performed to a depth of 15 feet below existing grade. The tests will be performed in general accordance with test procedures outlined in “Test Methods for Usual Condition, Open Hole Constant Head Exfiltration Tests – South Florida Water Management District, Permit Information Manual – Volume IV”. Proposal for Geotechnical Engineering Services Village of Pinecrest/Basin U35-S Village of Pinecrest, Florida ■ September 8, 2022 ■ Terracon Proposal No. PH8225098 4 Safety Safety is a critical aspect of all projects and a safety plan will be prepared prior to commencement of on-site activities; an onsite meeting will be held to discuss health and safety needs for this specific project with onsite personnel. Fieldwork is to be performed using OSHA Level D work uniform consisting of hard hats, safety glasses, protective gloves, and steel-toed boots. Increased levels of protection will be utilized while sampling activities are being conducted, in the event that increased petroleum or chemical constituents are encountered in soils or groundwater that present an increased risk for personal exposure. Exploration efforts require borings (and possibly excavations) into the subsurface, therefore Terracon complies with local regulations to request a utility location service through Sunshine State One Call of Florida (SSOCOF). We consult with the owner/client regarding potential utilities, or other unmarked underground hazards. Based upon the results of this consultation, we consider the need for alternative subsurface exploration methods, as the safety of our field crew is a priority. Private utilities should be marked by the owner/client prior to commencement of field exploration. Terracon will not be responsible for damage to private utilities not disclosed to us. If the owner/client is unable to accurately locate private utilities, Terracon can assist the owner/client by coordinating or subcontracting with a private utility locating services. The detection of underground utilities is dependent upon the composition and construction of the utility line; some utilities are comprised of non-electrically conductive materials and may not be readily detected. The use of a private utility locate service would not relieve the owner of their responsibilities in identifying private underground utilities. Site Access: Terracon must be granted access to the site by the property owner. By acceptance of this proposal, without information to the contrary, we will consider this as authorization to access the property for conducting the field exploration in accordance with the Scope of Services. Laboratory Testing The project engineer will review field data and assign laboratory tests to understand the engineering properties of various soil and rock strata. Exact types and number of tests cannot be defined until completion of field work. The anticipated laboratory testing may include the following: ■ Wash -#200 Sieve per ASTM D1140 ■ Moisture Content per ASTM D2216 ■ Organic Content per ASTM D2974 Our laboratory testing program often includes examination of soil samples by an engineer. Based on the material’s texture and plasticity, we will describe and classify soil samples in accordance with the Unified Soil Classification System (USCS). Proposal for Geotechnical Engineering Services Village of Pinecrest/Basin U35-S Village of Pinecrest, Florida ■ September 8, 2022 ■ Terracon Proposal No. PH8225098 5 Engineering and Project Delivery Results of our field and laboratory programs will be evaluated by a professional engineer. The engineer will develop a geotechnical site characterization, perform the engineering calculations necessary to evaluate foundation alternatives, and develop appropriate geotechnical engineering design criteria for earth-related phases of the project. Your project will be delivered using our GeoReport® system. Upon initiation, we will provide you and your design team the necessary link and password to access the website (if not previously registered). Each project includes a calendar to track the schedule, an interactive site map, a listing of team members, access to the project documents as they are uploaded to the site, and a collaboration portal. The typical delivery process includes the following: ■ Project Planning – Proposal information, schedule and anticipated exploration plan will be posted for review and verification ■ Site Characterization – Findings of the site exploration ■ Geotechnical Engineering When utilized, our collaboration portal documents communication, eliminating the need for long email threads. This collaborative effort allows prompt evaluation and discussion of options related to the design and associated benefits and risks of each option. With the ability to inform all parties as the work progresses, decisions and consensus can be reached faster. In some cases, only minimal uploads and collaboration will be required, because options for design and construction are limited or unnecessary. This is typically the case for uncomplicated projects with no anomalies found at the site. When services are complete, we will upload a printable version of our completed geotechnical engineering report, including the professional engineer’s seal and signature, which documents our services. Previous submittals, collaboration and the report are maintained in our system. This will allow future reference and integration into subsequent aspects of our services as the project goes through final design and construction. The geotechnical engineering report will provide the following: ■ Site Location and Exploration Plans ■ Boring logs with field and laboratory data ■ Stratification based on visual soil (and rock) classification ■ Groundwater levels observed during drilling ■ Subsurface exploration procedures ■ Description of subsurface conditions ■ Hydraulic conductivity (k-value) Proposal for Geotechnical Engineering Services Village of Pinecrest/Basin U35-S Village of Pinecrest, Florida ■ September 8, 2022 ■ Terracon Proposal No. PH8225098 6 EXHIBIT C – COMPENSATION AND PROJECT SCHEDULE Compensation Based upon our understanding of the site, the project as summarized above, and our planned Scope of Services, our lump sum fee is shown in the following table: Task Lump Sum Fee Subsurface Exploration, Laboratory Testing and Reporting $12,858.64 See attached Exhibit F – Fee Breakdown. Unit fees are based on the negotiated fees from Miami Dade County. Our Scope of Services does not include services associated with site clearing, wet ground conditions, tree or shrub clearing, or repair of/damage to existing landscape.
