') There is an existing canal south of 174th Street. The canal has mangrove vegetation and has been identified as a wetland in the General Permit application Number 050214-5 with SFWMD. The vegetated area is known to contain wetlands capable of sustaining halophytic vegetation (i.e. coastal wetlands) and has been documented to include mangroves. This wetland could be impacted by the proposed project if an outfall is proposed to this canal. ANALYSIS AND DESIGN RJ Behar is a multidisciplinary Engineering firm specializing in civil engineering, stormwater master planning, drainage improvements, transportation planning, traffic engineering, roadway design, water and sanitary engineering, utilities engineering and construction management. We are extremely qualified for this project and have designed miles of French drains and hundreds of injection wells, Mr. Juan H Vazquez, PE, our proposed Project Manager, was coauthor of the Florida Department of Transportation Exfiltration Systems Design Manual and specifically wrote the Injection well design portion of the manual. Our Design Approach will follow the steps listed below: 1. COMPLETE DA TA COLLECTION We have gathered a considerable amount of available information for this project. During design we will obtain any other available information needed. We propose to research the files of regulatory agencies having jurisdiction in the project area. This information should serve as a baseline of the drainage design improvements which will lead us to the best approach. ) Geotechnical exploration will be necessary to obtain data necessary to perform the required percolation analysis and to design the proposed improvements. The firm of HR Engineering (HRES) will be in charge of these services. They are located in Miami-Dade County and have ample experience with soil conditions in the area. We have worked together with HRES in more than 50 projects. They have indicated that the percolation maybe around 10-5 to 10-6 west of Collins Avenue. Data will be necessary for design of any injection wells. We have developed relationships with local well drillers that have data of injection capacities in the area, From previous permits in the area, we have found that there are wells in the proximity of the project. The design capacity of those injection wells was 750 gpm per foot of head. This is considered a good discharge capacity, Survey information will be necessary to develop drainage design and construction plans. FR Aleman will be in charge of topographic surveys, easement descriptions and plans, and utility explorations (SUE services). We have worked with them on several projects, Mr. Fernando Z. Gatell, P,S.M. is the Director of Surveying & Mapping for F.R. Aleman & Associates, Inc. He is responsible for all related operations. Mr. Gatell has over 35 years of experience, which covers all of the facets of Surveying and Mapping, from complicated boundary disputes to right-of-way, engineering, design, environmental, GPS, construction and specialized surveys. Also, a field visit will be conducted to familiarize the staff with critical areas that need particular attention and to identify any conditions that were not included in the data collection. The field visit will focus on identifying major factors contributing to the flooding sources through observation and interviewing with residents. The field reconnaissance will serve to establish drainage area boundaries and patterns. qr R .J.Behar R. J. BEHAR & COMPANY, INC. I RFQ No. 11-11-02 I 3
