Gifford Neighborhood Plan 2014 ➢ Stormwater Management Most of Gifford lies within the Indian River Farms Water Control District (IRFWCD). The district is the primary entity responsible for the provision of a stormwater outfall system. That outfall system is made up of sub-lateral, lateral, and outfall canals. The IRFWCD's facilities in Gifford include: ■ Sub-lateral canal A-6 (along the south side of 41St Street) ■ Sub-lateral canal A-7 (along the south side of 45th Street) ■ Sub-lateral canal A-8 (along the south side of 491h Street) ■ Lateral "A" canal (along the east side of 66th Avenue) ■ Lateral "H" canal (along the western edge of the old coastal dune) Maintenance of these facilities is funded by an IRFWCD assessment of all landowners within the IRFWCD. Stormwater Management is occasionally a problem in Gifford, especially due to localized flooding resulting from low areas that have no outfall. This problem generally occurs in areas developed prior to current stormwater management development regulations. Additionally, problems can occur when canals, ditches, swales, laterals, and sub-laterals not adequately maintained. In September 2000, the Board of County Commissioners established the East Gifford Municipal Service Benefit Unit (MSBU) that includes an area of Gifford that is not within the boundaries of a water control district. Current total annual assessment for this MSBU is $990.00. The assessment was higher in earlier years when larger projects were ongoing. That area includes approximately 43 acres and is bordered by 43`d Street on the north, 41St Street on the south, the FEC Railroad on the east, and the IRFWCD boundary (24th Avenue) on the west. Since the area is not within a water control district, poor drainage has been a constant problem for residents in that area. To eliminate drainage problems, the County Public Works Department uses MSBU funds to make drainage system improvements and provide maintenance within the 43 acre area. Improvements completed include swales and storm drain piping to collect and route stormwater into the large stormwater detention pond located at the northwest corner of 41 st Street and the FEC railroad tracks. The system is primarily for flood control, not water quality treatment. East Gifford Area Stormwater Improvement Project The East Gifford Area Stormwater Improvement Project involved construction of a 4.64 acre wet stormwater detention pond and swales at the northwest corner of FEC Railroad R/W and 41st Street. The project improved drainage in the area by routing stormwater into the pond with eventual outfall into the canal abutting 41st Street. Before this system was constructed, stormwater N from this section of Gifford area caused flooding and discharged untreated stormwater into the Indian River Lagoon. The project's N drainage area is a 46.8 acre watershed lying north of 41st Street, east of the one mile ridge (approximately 26th and 28th Avenue), Indian River County 43 Community Development
