City Engineer City of Sunny Isles Beach 18070 Collins Avenue Sunny Isles Beach, FL 33160 RE: 174th Street Storm Water and Pavement Improvements Dear Ms. Gray, W W W. C R A I G A S M I T H. C O H Per our meeting with Elka Linton -Dorsett and Bill Evans, the City has determined that they wish to perform a full reconstruction of 174th Street from Collins Avenue to North Bay Road and a complete milling and resurfacing from North Bay Road to the western terminus of 174th Street. The preference is also to extend the stormwater system to the west to tie into the North Bay Road outfall. In addition, the City would like to reconstruct sidewalk as needed to include ADA compliance, provide traffic calming devices, replace curb and gutter as needed, minimize median openings, add conduit sleeves to medians for future use, include a construction phasing plan to provide uninterrupted use of City Bus Shelters and landscape within the right of way and project limits. Due to the assumed subsurface conditions, a geotechnical evaluation will be required to determine the extent of the existing unsuitable material and establish a suitable roadway cross section to property support the roadway infrastructure and its components. Depending on the outcome of the geotechnical testing, it may be necessary to provide a structural reinforcement to the base material in the form of geo- grid or alternative as well as possible structural support fo`r drainage structures. The City has also requested that CAS prepare the necessary contract documents and specifications for the project, oversee the bid process and contract award for construction. Lastly, it is understood that in the future, the City would like CAS to perform adequate site inspection and engineering services during construction to provide final project certification. CAS is pleased to provide the required services needed to complete the described project. The limits of the project will be on 174th Street beginning at the east end at Collins Avenue (SR-A1A) to western limits of 174th Street. Also included will be necessary Survey of North Bay Drive from approximately 260 feet north of 174th Street to approximately 300 feet south of 174th Street. The total linear footage of the project is approximately 2,515 feet, just less than one half mile. 954•.782.8 22-2 --•S6.4.7 9S4.766.8927 ATTACHMENT "A" -- = 0 5.4 6 1.. 4-4 1 0 x 791.9818 210
