• BACKGROUND Citrus Springs is a proposed development located near the northeast comer of 584' Ave. and 5* Street SW. Refer to Exhibit -A. A 16 -inch Master Plan Water Main is scheduled for construction along the Developer's property. The 16 -inch Master Plan water main is slated for construction on an "as -needed" basis driven by development. The proposed 6-mch force main provides an extension of the wastewater collection system to serve the proposed development, surrounding residentmL future development and has the ability to loop the County's South Regional and West Regional Wastewater Collection Systems. The County's Wastewater Collection System is comprised of five independent regional service areas (North, South, Central, West Regional and Sea Oaks WWTFs) which geographically make up the Countywide Wastewater Collection Systems. Extending a force main along 5d' SW from a force main on 58'h Ave. to a force main on 43`d Ave. would hydraulically interconnect the County's South and West Regional Service Areas. Just as looping of water mains in a distribution system. the effects of looping a force main provides a similar level of redundancy and hydraulic balancing of flows. The 6 -inch force extension / looping has the ability to divert a portion of the sewage flow to either the West Regional or South Regional Wastewater Collection Systems for Tn atrnent and Disposal. Until this opportunity, each of the regional wastewater collection areas had not expanded sufficiently to allow for the interconnection of the regional collection areas. The Sun Tree Partners Inc. have agreed to enter into a cost sharing agreement with the County to construct the Coumv Master Plan Water Main and the proposed Force Main Extension / Looping System in conjunction with their site development. Attached is a proposed Developer's Agreement with Sun Tree Partners Inc. for reimbursement of a portion of the subject waterlines and wastewater lines (Refer to Exhibit -B). A description of the proposed Master Plan line and Force Main Looping System is presented below and discussed in further detail in the Developers Agreement. A COUNTY MASTER PLAN 16 -inch Water Main along 5`� Street SW from 58' Ave. to 43`d Ave.: Furnish and install a 16 -inch water main along 5' Street SW from Icings Highway (584i Ave.) east to 43r4 Avenue. Make connection to an existing 16 -inch water line located on 43rd Avenue. The proposed 16 -inch water main shall extend approximately 5,453 +/- lineal feet. B FORCE MAIN EXTENSION/LOOP — 6 -inch Force Main along 5`h Street SW from 58`h Ave to 43`° Ave.: Furnish and install a 6 -inch force main along 5d' Street SW from Icings Highway (581, Ave.) east to 43r4 Avenue. Make connection to a future 6 -inch force main to be located on 43' Avenue. The proposed 6 -inch force main for this DEVELOPMENT shall extend approximately 5,453 +/- lineal feet to 43rd Ave. The DEVELOPER shall make connection to a proposed 6 -inch force main to be constructed along 43'd Ave. by another Developer known as Arbor Trace. Refer to Exbibit-D. Staff is currently negotiating with the owners of Arbor Trace to over -size their required force main along 43'd Ave. to handle the projected sewage flows from the proposed Citrus Springs Development as well as the surrounding community. Staff will be bringing a proposed Arbor Trace Developer's Agreement to the Board in the near future. ANALYSIS As shown in Exhibit C-1 of the attached agreement. the estimated cost sharing between the Developer and the County for a 16 -inch County Master Plan Water Main along 5" Street SW from 58`b Ave. to 43"' Ave. is presented in the Agreement and summarized below: As shown in F.zhibit C -Z of the attached agreement, the estimated cost sharing between the Developer and the Countv for an 6 -inch County Force Main Extension / Loop along 5`h St. SW from the 58`h Ave to 43rd Ave. is presented in the Agreement and summarized below: June 20, 2000 103 BOOK iv_ -L C,
