HomeMy WebLinkAboutSubmittal CD Q.17, Water Supply17. WATER SUPPLY A. 1. Provide a projection of the average daily potable and non - potable water demands at the end of each phase of development. If significant seasonal demand variations will occur, discuss anticipated peaks and duration. Use the format below: Table 17-1, Projected Potable Water Demand, provides a breakdown of the estimated daily potable water demand for both the remaining unreserved development program of Increment I and the entire development program of Increment II. At project completion, the projected total potable water demand is estimated to be 2,837,375 gallons per day (gpd). No significant demand for non -potable water is anticipated. No significant seasonal demand variations are anticipated. While the projected potable water demand created by new development in Increment II is 2,837,375 gpd, the actual demand created for water by Increment II will be 2,837,375 gpd minus the demand allocated for the existing development that is replaced. According to the policy of the Miami -Dade County Department of Environmental Resource Management (DERM), when an existing building is demolished for new development, the water demand allocated for the demolished building is transferred and credited to the new development. Considering the variability of time and location for development under the DDRI, it is not practical to estimate the amount of allocated water demand from demolished development that will be transferred to new development. While the figures provided in Table 17-1 represent the total demand created by new development in Increment II, they do not demonstrate the actual demand for water created by Increment II, which would be significantly less. 2. Describe how this demand information was generated, including the identification of the consumption rates assumed in the analysis. Projections of the average daily potable water demand have been estimated based on Miami -Dade Water and Sewer Department (WASD) usage rates. For land uses for which usage rates were not available, rates were estimated. The WASD demand rates are provided in Table 17-1, Projected Potable Water Demand, under the column titled Demand Rate.

The Downtown Development Authority is applying for approval of Increment II of the Downtown Miami Development of Regional Impact (DRI). The purpose of the DRI is to simplify and expedite the process for the impact review of large-scale development. It has been used in the review of the American Airlines Arena, the Performing Arts Center of Greater Miami, and major residential and hotel projects in the Brickell and Omni areas of downtown Miami. The project area contains approximately 880 acres of intensive urban development. Approximately 78 acres of the DRI are currently zoned and developed as City parks. An aerial map showing the project location is enclosed. Also enclosed is a summary of the development progran-lin table form showing the proposed land uses and amounts pursuant to the guidelines and standards in Chapter 28-24, F.A.C. Increment I, which was originally approved in 1988, and Increment II, which is currently being proposed, specify the type and intensity of land use in downtown Miami through the year 2009. We will notify you if the development program for Increment 1 is adjusted. Please note that the DDA is currently proposing to expand the boundary of the Downtown DRI to make its boundary consistent wren the boundary or the DDA. Tnis boundary expansion Is not expected to affect the development program for increment II. Please consider the proposed expanded boundary area in your analysis. Please indicate in your response whether or not your present facilities and staffing are capable of serving the Project. If not, please specify the additional staffing/equipment necessary to do so.

Rob Curtis, The Curtis & Kimball Company MiAMI-DADE COUNTY, FLORIDA ENVIRONMENTAL RESOURCES MANAGEMENT OFFICE OF THE DIRECTOR 33 SW 2r° AVENUE MIAMI, FLORIDA 33130-1540 ,(305) 372-6754 FAX (305) 372-6759 March 26, 2002 `rhe Curtis Kimball Company Mr, Rob Curtis 7520 Red Road, Suite Nt South Miami, FL 33 146 Re: Downtown Miami Development of Regional Impact, Increment 11 (DDI ) Dear Mr. Curtis: DER.M staff recently reviewed the Application for Development Approval (ADA) for the DDRI. According to our review, the subject application meets the minimum requirements of Chapter 24 of the Code of Miami -Dade County and the initial development order for increment H. of the DDRI may be 'approved. During the course of the review, DERNI sta 'made the foliowing Potable Water Supply: The subject property is located within the franchised water service area of the Miami -Dad Sewer Department (MIDWASD). Water mains exist throughout the area. The source of water for these mains is MDWASD's Hialeah -Preston Water Treatment Plant, which has adequate capacity to meet projected demands from this project. The plant is presently producing water, which meets Federal,. State and County drinking water standards. The estimated potable water demand for the proposed land uses in "Downtown Miami Increment IF" is approximately 2,107,000 gallons per day, irrigation demand is not included in this estimate. Notwithstanding that adequate system capacity is available for this project, DERM will require that .water conserving plumbing fixtures be installed in accordance with the requirements of the South Florida Building Code in order to use more efficiently the southeast Florida water resources. It is rz...ornmended that the landscaping conform to xeriscape concepts. Included in theseconcepts is use of drought tolerant plants, reduced use of turf grass together with efficient irrigation system desip. Details of xeriscape concepts are set fonh. in the "Xeriscape Plant Guide from the South Florida Water Management District. 1...)owntown Nida.mi Development of Regiorial (DDRI) P2 )ewer Service: The property is located within the NiDWASD's franchised swer service area that is currently serviced by existing public sanitary sewer mains, This collection system includes a network of gravity lines and force mains throughout the subject area. Wastewater is directed through several pump stations, depending on the specific location within the subject area. Pump stations involved include: 30-0002 .fc:il- the northern part of the site, 30-0001 for the central, 30-0008 for the southern part along Briekell Avenue and 30-0156 servicing Brickell 'Key., All mentioned pump stations are currently working within the mandat..i criteria set forth in the First Partial Consent Decree. Pump stations 30-0001 and 30-0002 have sufficient capacity for all estimated development. However, pump station 30-0008 and 30-01.56 could only received 882,960 GPD and 193,380 GPD respectively before they exceed the mandated criteria set .forth in the First Partial Consent Decree. 'Notwithstanding the foregoing, in light of the fact that the County's sanitary sewer system has limited sewer collection/transmission and treatment capacity, no new sewer service connections can be permitted until adequate capacity becomes available. Consequently, finaldevelopment orders for this site may not be granted unless adequate capacity in the .s'eutitary sewer collection/transmission and treatment system is available: at the point in time when the project will be contributing sewage to the system or if approval for alternative means of sewage disposal can be obtained. Use of an alternative means of sewage disposal shall be an interim measure, with connection to the public.: sanitary sewer system required upon availability of adequate collection/transmission and treatment capacity,. Sewage treatment and disposal for the area is provided by MDWA.SD's regional wastewater treatment and disposal facilities These facilities have limited available capacity.; consequently, approval of development orders which will generate additional wastewater flows are being evaluated by DERM on a cast -by -ease basis. Approvals are only granted if the application for any proposed development order is certified by DERM so as to be in compliance with the provisions and requirements of the settlement agreement between Miami -Dade County and the State of Florida Deparunent of Environmental Protection, and also with the provisions of the Environmental Protection Agency Consent Decree. The above infoi nation is being transmitted to you at your request, and is based upon current Code requirements and the available information contained in the ADA., It is recommended thatactual design development be closely coordinated through this office to insure compliance with all applicable Code requirements. Should you h.ave any questions or be in need of additional information, please advise. Sincere Enrique A.
