Date Description 12/20/2016 BCC approve funding mechanism 12/2016 to 04/2017 Bid project 05/2017 Begin project if a responsive and responsible bidder submits* 05/2018 Finish Project** Summer 2018 Begin to connect property owners * The grant agreement specifically states: "If the construction, which is eligible for District reimbursement, does not begin before June 30, 2017, or if the first invoice for non -construction projects is not submitted by June 30, 2017, the cost -share agreement will be subject to termination and the funds subject to reallocation." ** The grant agreement terminates on June 30, 2018. There is an option for extension, but such requests must be made on or before April 1, 2018. There is a tight timeline imposed by the SJRWMD to expedite completion of the work. Attachment 4 contains the SJRWMD cost share grant. CONNECTIONS: In addition to determining the financing mechanism for the project, a connection policy should be revisited. New Construction The County's land development regulations (LDR) spell out the requirements for new development as it relates to utility connections. Section 918.05 - Water and Wastewater Connection Requirements for New Development has a connection matrix (as shown in table 3.A.16 and 3.13.19). For parcels inside the Urban Service Area (USA) where centralized water and/or sewer services exist, the LDRs require that those parcels connect to the system. No changes to the LDR section 918.05 are proposed. Existing Structures In order to assist in the financial viability of this project, the BCC should consider whether or not mandatory connections are applicable. Awaiting voluntary connections would transfer the full financial obligation of the project onto the utility for an unspecified amount of time. Unused capacity in the system would cost the utility more in terms of maintenance or premature replacement costs. Having sewer lines designed and built for optimum build -out but presently underutilized due to limited demand can cause flows to stagnate, build- up of solids, blockages due to hardening of material deposits and unwanted methane or decomposition gases in partially full lines. Such gases wreak havoc on associated parts and pieces of a centralized system due to their corrosive nature. The sustainability of a project such as this depends on the number of connections achieved after the centralized sewer has been installed. Out of 61 parcels in the Phase 1 area, 38 parcels have structures currently served by on-site treatment and disposal systems (OSTDS), otherwise known as septic tanks. The 38 parcels would need to connect to the proposed centralized system in order to .realize the approximate annual elimination of 2,190 pounds of Total Nitrogen (TN) and 365 pounds of Total Phosphorous (TP). Presently, if their tanks fail or need repair, a Florida Department of Health (FDOH) permit is required. A FDOH permit is issued if no such centralized system is in place. However, should the project be built, any future septic tank failures along US Highway 1 within the project area could be required to connect in concert with the following local and state laws: IRC Ordinance Section 201.03 — Connection with Sewer System required.
