INTRODUCTION We understand that the western end of the existing developed residential street has experienced flooding problems and the existing pavement at the cul-de-sac at the end of the street is not large enough for large vehicles. The City wishes to improve approximately 500 feet of the end of this roadway with additional drainage, an improved cul-de-sac and resurfacing. There is one existing drainage inlet near the end of the street with a small existing outfall to the Atlantic Waterway. The existing residences along this street have constructed brick and concrete driveways abutting the asphalt pavement. As requested, the proposed drainage and resurfacing is to be designed with as little as possible disturbance to the existing driveways or the adjacent landscaped areas in the right-of-way. This proposal includes a survey of the area, roadway improvement plans, specifications and permitting for the project. TASK 1 - TOPOGRAPHIC SURVEY & GEOTECHNICAL TESTING CWI will provide surveying services through a Subconsultant. This topographic survey will include elevations of the existing roadway, cul-de-sac and driveways, cross sections and a topographic survey of above ground features including landscaping and meter boxes, utility poles, etc. The existing 60 foot right- of-way lines will be shown along with the existing landscaping. This also task includes one Open Hole Percolation test for the drainage design. This test will be used in the design of the drainage system and drainage permitting. TASK 2 - PA VING, GRADING AND DRAINAGE IMPROVEMENTS This task will include a drainage analysis, based on the existing and proposed conditions. CWI will prepare Paving, Grading and Drainage Plans, at 11 "xI7" size, for the proposed improvements. The plans will include two new drainage structures in the locations identified during our site meeting, new drainage piping (approximately 370 feet between new structures), connection to the existing outfall (size unknown) to the Atlantic Waterway on the south, and roadway resurfacing. The existing outfall is located near the western end of the street, between two residential properties. The proposed drainage system is to be connected to this existing inlet and outfall. The existing inlet is planned to be replaced in order to connect Civil Works, Inc. 10 NW 42 Avenue, Suite 200, Miami, FL 33126 Ph: 305-448-5955 Fax: 305-448-5466
