Contract #36528 ATTACHMENT A - STATEMENT OF WORK MOORHEN MARSH LOW ENERGY AQUATIC PLANT SYSTEM PROJECT I. INTRODUCTION/BACKGROUND The State of Florida General Appropriations Act FY 2021 provides funding under line item 1641A to the District for water quality projects that reduce nutrients, total phosphorus (TP) and total nitrogen (TN) and restore flow to the Indian River Lagoon (IRL). On November 18, 2020, the Florida Department of Environmental Protection (FDEP) endorsed projects on the District's scored and ranked project list. At its December 8, 2020 meeting, the Governing Board approved Recipient's proposal for cost -share funding. Indian River County (Recipient) requested funding for their Moorhen Marsh Low Energy Aquatic Plant System (LEAPS) project (Project) for the not -to -exceed amount of $1,250,000, towards the estimated construction cost of $5,500,000. The Recipient is located in Indian River County. II. OBJECTIVES The objective of this contract is to provide cost share dollars that will enable the Recipient to provide a water quality benefit to the IRL by significantly reducing the nitrogen and phosphorus nutrient load to the IRL. III. SCOPE OF WORK The Recipient will construct a system to treat water from the Indian River Farms Water Control District's North Relief Canal. The system is based on water treatment and nutrient recycling technology oriented around the cultivation of select aquatic plans within an engineered platform. The system will use aquatic vegetation to remove nutrients and settable suspended solids from canal water. The nutrient sludge precipitate in the aquatic vegetation scrubber basins will be collected and dried. The water in the basins will be reoxygenated before being discharged back into the canal. The aquatic vegetation will be harvested regularly using a long reach excavator. The harvested vegetation will be composted if possible or mixed with other vegetation or disposed of at the landfill. The sludge may be used as a landfill cover soil supplement. IV. PROJECT ADMINISTRATION AND DELIVERABLES The Recipient shall be responsible for the following: • Complete and obtain final project design, construction plans, and specifications; • Obtain all required permits, including right of access to the project sites, related to project construction and subsequent operation and maintenance of the completed work; • Assure compliance with all permits and permit conditions; • Provide procurement for project construction; • Perform supervision and inspection of construction; • Perform construction contract administration; • Assure compliance with cost accounting practices and procedures required for reimbursement of cost share funds expended. - 11 -
