Mr. Mark Castano <br />Keith <br />Proposal for Geotechnical Study - Proposed Bella Vista Park <br />March 30, 2022 <br />Page 2 <br />NV5 Proposal No. 22-0300REV1 <br />We understand the site will be redeveloped with a park comprising a small welcome building that <br />would be also a marine patrol office, and house watersports rental, and a new bulkhead and dock. <br />PURPOSE <br />The purpose of NV5's services on this project will be to perform a subsurface exploration and <br />engineering analyses to provide recommendations for design and construction of the proposed <br />project. <br />PROPOSED SCOPE OF ENGINEERING SERVICES <br />1. We propose drilling two borings. One of the borings would be drilled to around 40 to 50 feet <br />below grade close to the shoreline. A second boring will be drilled further inland and will extend <br />to 15 to 20 feet below grade. Proposed boring locations are shown with red circles in the <br />image below. We have not visited the site, and assume at this time that we can access the <br />site from the parking lot to the north, or the property immediately east. Boring locations could <br />shift due to actual site conditions. <br />The borings will be drilled utilizing the rotary wash method with a truck -mounted drill rig. <br />Samples of the subsurface materials encountered will be collected continuously down to 10 <br />feet below ground surface. Below that depth the sampling will be performed at roughly 5 -foot <br />intervals. Sampling will be performed using a Standard Penetration Test (SPT) sampler per <br />ASTM D-1586. Upon completion of the borings, the boreholes will be grouted to the ground <br />surface. <br />2. In addition to the borings, we propose performing one (1) field permeability test to provide <br />information for drainage design at the site. The test will be performed to 15 feet below the <br />existing grade in general accordance with the South Florida Water Management District's <br />Usual Open Hole Procedure. Upon completion of the test, the borehole will be abandoned with <br />grout to the ground surface. Test location can be coordinated with the project civil engineer <br />as appropriate. <br />M1 <br />CONST -RUCTION QUALITY ASSURiA 10E INJf RASMUC'FURE ENJERM PROGRAiNI OMAN AGEN]EiM CNVIR0NNIFN FAT_ 444 <br />
