HomeMy WebLinkAbout1990 08 - Engineer's Preliminary Plana C H E S S E R' S G A P PRELIMINARY PLAN FOR A COMMERCIAL PLANNED UNIT DEVELOPMENT FOR SEBASTIAN GENERAL PARTNERSHIP B.F.T. PREPARED BY: MOSBY & ASSOCIATES, INC. 1507 - 20TH STREET VERO BEACH, FLORIDA 32960 August 1990 SECTION 20A-4.13 PRELIMINARY DEVELOPMENT PLAN r_nrnmTnM The proposed Chesser's Gap Commercial Planned Unit Development is located on a tract of land lying approximately 3.5 miles west of U.S. #1 and the Florida East Coast Railroad on the south side of C.R. 512. The site comprises 58.09 acres. PRESENT USE The project site is presently used for agriculture. Land surrounding the proposed development is generally undeveloped residential land, except the land abutting the north property line which is undeveloped commercial. PLANNING OBJECTIVES It is the intent of the Sebastian General Partnership to create a Planned Unit Development containing Commercial, Professional and Light Industrial uses blended together in an aesthetically pleasing format. All buildings will be designed and constructed of the finest materials to compliment the overall project. The entrance and overall site will be landscaped and maintained to present a clean and beautiful experience for the public visiting the project. Specific facilities will include a supermarket, a general merchandise department store, an assortment of specialized retail shops, office complexes and high-tech light industrial units. Efforts are presently being made to include an Elks Lodge and a County Municipal facility. If these efforts fail, then these lands will be used as commercial. It is the overall belief of the developers that the proposed project will fulfill the need for a centrally located shopping facilities for the public.

The project will be constructed in three (3) phases, which will be a continuing, evolving process of cooperation between the City of Sebastian and the Sebastian General Partnership B.F.T. The project will be broken down as follows: -3- Phase I January 1991 to January 1992 This phase will be the construction of the proposed Fleming Street Thoroughfare Extension. In addition, this phase may include the development of the proposed supermarket and some retail shops. The landscaping, overall drainage system, utilities and traffic improvements will be completed during this phase. Phase II January 1991 to June 1994 This phase includes the development of a portion of the proposed Professional Office/ Commercial area as well as a portion of Light Industrial area. Phase III June 1994 to January 1996 This phase will include the development of the remaining Professional Office/Commercial and Light Industrial areas. ENVIRONMENTAL IMPACT STATEMENT No wetland areas exist on the project site. Lakes are to be utilized for stormwater retention. These lakes will be interconnected and protected against direct discharge of surface runoff by utilizing natural drainage concepts. Approximately fourty percent (400) of the gross site is to be used as grassed areas for runoff. These stormwater managerial practices will have a beneficial impact on the water resources in the area, including the opportunity for groundwater recharge. Landscape buffers will be established to provide both noise and sight buffers. Mounds of earth with tree and shrub plantings will be utilized. The existing vegetation along the east, west and south property lines will be maintained as much as practicable. Whenever possible, existing trees within the project will be main- tained. PRELIMINARY DRAINAGE PLAN The drainage system presently consists of a roadside ditch along C.R. 512, and a major drainage ditch along the west property line. The ditch along C.R. 512 discharges into other collector ditches which discharge ultimately into the Indian River. The existing topography of the land is such that nearly all of the rainfall results in ponding and eventually runoff into the adjacent ditches. The detention time is minimal, thereby reducing the advantage of recharge of the surficial aquifer. -4- PRELIMINARY DRAINAGE PLAN (continued) The proposed drainage system consists of a complex network of centralized lakes, swales and underground pipes. Best managerial practices include grassed swales, berms around lakes and establish- ment of littoral zone vegetation. The design of the stormwater management system will be such that the runoff from a twenty-five (25) year storm will be retained on-site with provisions for an overflow, thus providing a detention time that will allow the collected stormwater to be used to recharge the surficial aquifer and to make provisions for use of the storm - water for non -potable irrigation water, if desired. PUBLIC FACILITY IMPACT STATEMENT A. Wastewater Generation The wastewater system for Chesser's Gap is to be tied in to the North County Wastewater System which is presently under construction. Indian River County has already installed at the project's north west corner of the property. The following is the estimated quantity of wastewater generation: Retail 175,400 ft2 Total Bldg. Area x 0.1 GPD/ft2 = 17,540 GPD Professional Office 105,100 ft2 Total Bldg. Area x 0.2 GPD/ft2 = 21,020 GPD Light Industrial 77,000 ft2 Total Bldg. Area x 0.2 GPD/ft2 = 15,400 GPD Organizational 10,800 ft2 Total Bldg. Area x 0.3 GPD/ft2 = 3,240 GPD Total Estimated Wastewater = 57,200 GPD As you can see from the above calculation, the estimated waste- water flow is based on square footage of the buildings which is a conservative approach to the calculation of the waste- water flows. B. Water Required The planned potable water source for this project is from General Development Utilities. The amount of potable water required is estimated at 57,200 GPD. It should be noted that the above estimated potable water re- quired does not include water for irrigation nor building fire systems. It is intended to use non -potable water for these purposes. -5- C. Recreation Facilities The Green Areas around the professional office area adjacent to the lakes will be equipped with facilities such as benches and tables for the employees of these buildings. D. Estimated Number of School Age Children There are no developmental units planned for the project, there- fore, no generation of school age children. E. Estimated Property Taxes . The estimated property taxes are as follows: Phase I A moderate increase to the tax revenue is expected to result from Phase I. No sales tax revenue is expected from Phase I. Phase II A significant tax revenue increase is ex- pected as a result of Phase II. Taxable values are expected to exceed $10,000,000.00 and bring in tax revenue in excess of $1,000,000.00. Sales tax revenue is ex- pected to top $500,000.00. Phase III This phase will see the completion of the project with total taxable values exceeding $30,000,000.00 with tax revenues above $10,000,000.00 and sales taxes over $16,000,000.00. TRAFFIC INFORMATION A detailed traffic impact analysis was performed by Motorist Design Data Movement, Inc. of Merritt Island. It is recommended that a traffic signal at the C.R. 512 and Fleming Street intersection be installed. Also that an east bound deceleration lane for right hand turns into the project, a west bound left turn lane into the project and a dual exit lane be constructed. A copy of the report has been submitted to the City. SUMMARY One positive impact that the proposed project will have is that it will provide centralization of commercial, professional and light industrial services for citizens of Sebastian. The project will be developed in such a fashion that the City leaders and citizens will be proud to have such a development within their City.
