N485 Design & Construction-Pasco County Lexington Oaks Golf Course Reclaimed Water Transmission and Storage Pond Project Project Type AORs Water Supply Cooperative Funding Strategic Initiatives Reclaimed Water Pasco County Cooperator(s) Project Manager Anthony Andrade Task Manager(s) Status Proposed Coop. Funding Application Recommendation Fund as a High priority. The project addresses water supply priorities of the Board by implementing reclaimed water supply in the South Central portion of Pasco County. The project is local in its implementation, however it will provide regional benefits as it is near regional potable water wellfields. The cooperator has confirmed it will request the necessary matching funds in a future capital improvement program budget and has started preliminary design (no District funding). There was sufficient data submitted to evaluate the project, it is within the Board's statutory authority to fund, and it is not the result of a permit requirement or enforcement action . The County ranked this project 15th on their list of 15 FY2013 CFI requests. Description This proposed FY2013 project is for the design and construction of 4-inch diameter reclaimed water line to provide additional reclaimed water to the Lexington Oaks Golf Course and subdivision. The project will also include a in-pond barrier to create a separate reclaimed water pond inside the golf course's existing on-site storage pond. Benefits The project will create 1 million gallons of reclaimed water storage to supply 0.12 mgd of reclaimed water and offset 0.09 mgd of potable quality groundwater currently used for irrigation. Costs The total cost of the project is estimated to be $122,000, Pasco County has requested $61,000 in FY2013 funding from the District for fifty percent of the funding. The estimated cost, amortized at 8 percent over 30 years is $0.33 per 1000 gallons offset. Additional Information The golf course has been limited to the amount (0.18 mgd) of reclaimed water it can use due to pH and scaling issues caused by the co-mingling of reclaimed water and stormwater and long residence time in the existing 8 acre pond. The apparent hardness of the water from the pond has caused emitters in the irrigation system to become clogged forcing the irrigation system to be off line and serviced on a fairly regular basis. The abnormally high pH level in the pond is believed to be the major cause of the scaling and impact to the irrigation system. High levels of algae and the photosynthetic uptake of carbon dioxide in the pond has caused this pH issue. The pH level has been brought down by using an acid injection system; however, the average monthly cost of this remedy is approximately $4,000. This has proven to be an economic hardship to the golf course operation. The consensus solution is to segregate the reclaimed water from the rest of the pond by building a barrier that will allow the an additional 0.09 mgd of reclaimed water to be used as the separated reuse will have less retention time and interaction with the remainder of the waterbody. This will consist of a sheet pile structure that will retain approximately 1 million gallons. This storage quantity will be enough water for several irrigation cycles allowing for adequate recharging of the new segregated storage pond with reclaimed water.

N489 WMP Update - Pasco - Anclote River Watershed Project Type AORs Water Quality Natural Systems Flood Protection Cooperative Funding Strategic Initiatives Water Quality Maintenance and Improvement Minimum Flows and Level Establishment and Monitoring Emergency Flood Response Pasco County Cooperator(s) Project Manager Richard Mayer Task Manager(s) Status Proposed Coop. Funding Application Recommendation Fund as a High priority. This proposed project is to update a Watershed Management Plan (WMP) for the Anclote River Watershed east of the Suncoast Parkway. Description This is a proposed project to perform the Maintenance of Watershed Parameters and Models element of the District's Watershed Management Program (WMP) for the Anclote River Watershed east of the Suncoast Parkway. The project area is 50 square miles, located in Pasco County. The Watershed Evaluation and Management Plan were completed in 2012 based on topographic information gathered in 2004. This project consists of updating the Watershed Evaluation and Management Plan by incorporating topographic information collected by the Light Detection and Reflection (LiDAR) method in 2011, and recent ERP data. With FY2013 funding the update of the Watershed Evaluation, and begin updating the Watershed Management Plan. The Watershed Evaluation update includes refinement of the geodatabase and preliminary model features. The update of the Watershed Management Plan includes refining the watershed model parameterization, the computer model, and floodplain analysis. Future funding will be needed to complete the peer review of floodplain results, public notification, public meeting, Governing Board approval of the updated floodplain results, surface water resource assessment (SWRA), establishment of level of service (LOS), and Best Management Practices (BMP) alternative analysis. It is anticipated that future funding may be required to complete the remaining tasks. Benefits The information developed provides the science for the District's resource management and Environmental Resource Permitting (ERP) responsibilities. Completing elements of the District's Watershed Management Program is one of the District's Strategic Priorities for managing the water resource, and provides information to local governments to address land use changes and stormwater management within a specific watershed. It assists local governments with their land management responsibilities by identifying the floodplain, establishing a level of service, evaluating BMPs to address level of service deficiencies, and providing a geodatabase and projected results from watershed model simulations for floodplain management and water quality management. Costs The projected cost for this project is $300,000 of which the District's share is $150,000 and the County’s share is $150,000. For FY 2013, $150,000 has been requested by Pasco County to update the Watershed Evaluation and begin an update of the Watershed Management Plan. The County would also contribute $150,000 as revenue. Future funding may be required to complete the project. Future funds identified for the project are contingent upon approval of such amounts by the Governing Board in the annual budget. When each task is completed, the project cost and scope may require refinement based on the information gathered and unforeseen circumstances. The District funding amount shown in the table includes staff salaries. Additional Information The WMP includes five major elements: 1) Topographic information, 2) Watershed Evaluation, 3) Watershed Management Plan, 4) Implementation of Best Management Practices, and 5) Maintenance of Watershed Parameters and Models. Implementing elements of the WMP with local governments is one of the District's Strategic Priorities. The development of watershed models and plans to identify potential projects or BMPs will help to resolve or mitigate water resource issues. The District has worked with the County to develop an implementation schedule by watershed based on their projected funding levels. Over $15,000,000 has or is being spent to provide high accuracy Watershed Management Plans throughout the County. In order to protect this investment these Plans must be updated to reflect changes continually occurring in the various watersheds. The LIDAR data collected in 2011 would be incorporated into the plan. The District is managing the project by entering into agreements and purchase orders to accomplish project tasks. A revenue agreement will be developed with the cooperator. 61
