ATTACHMENT A PROJECT WORK PLAN PROJECT: East Roseland Stormwater Improvement Project LEAD ORGANIZATION : Indian River County ' s Public Works Department, Stormwater Management Program COOPERATING ORGANIZATIONS : 1 . St. Johns River Water Management District (SJRWMD) Stormwater Cost Share Program 2 , Roseland Property Owners Association 3 . SJRWMD Watershed Action Volunteer Program 4 , Indian River Lagoon Program, SJRWMD PROJECT LOCATION : NPS Priority Watershed--Indian River Lagoon Hydrologic Unit Code : 03080203 The longitude of the project site is 80°E 29 ' 22 " and the latitude is 27°N 50 ' 15 ". The site is located within the Fleming Grant, Section 21 , in northern Indian River County. The project, the creation of two stormwater detention ponds, will provide flood control and stormwater quality treatment for a 124 . 5 -acre watershed in Roseland. The watershed lies east of the Florida East Coast Railroad (FEC) and west of US Highway 1 , north of the City of Sebastian and south of the St. Sebastian River, Figure A shows this watershed ' s location with respect to Brevard County and the Indian and St. Sebastian Rivers . The Roseland project will reduce the frequency and severity of flooding within the natural slough just south of Bay Street. The area is subject to nuisance flooding that causes road access problems. The creation of additional flood storage in two wet detention ponds and the construction of control structures to bleed down each lake will improve the quality of discharge flowing to the St. Sebastian River. This project is currently in the initial design phase through funding provided by the County and the St. Johns River Water Management District (SJRWMD) . The vast majority of the 124 .5-acre watershed drains northeastward toward the Indian River Lagoon. This project is proposed to improve water quality in the St. Sebastian River (designated a Class III Aquatic Preserve by Florida Department of Environmental Protection (FDEP)) and in the Indian River Lagoon system, an "estuary of national significance" (designated by Environmental Protection Agency ' s (EPA) National Estuary Program). This is to be accomplished by capturing stormwater runoff and routing the water into two detention ponds for treatment prior to discharge into the St. Sebastian River. WATERSHED RESTORATION ACTION STRATEGY: This project is included as part of the Indian River County 2020 Comprehensive Plan and has been requested by the Roseland Property Owners Association. It is also listed as a project for completion in the Indian River County Comprehensive Plan ' s Capital Improvement Program Element. Contributions from local governments, like Indian River County, in Action FSD- 13 to be completed during the next two years (IRLCCMP, revised 1998) are estimated at $ 6,000, 000. Completion of the East Roseland project will address stormwater improvements and directly supports the IRLCCMP, Action FSD- 13 , "Upgrade Existing Stormwater Drainage Systems" (IRLCCMP, page 122) . It also is listed as a priority objective in the 1994 Indian River Lagoon Surface Water Improvement and Management Plan (SWIM), revised 1994 . In this plan (page 100), it states that "stormwater runoff is considered to be the single most significant source of pollution for most surface waters. " Furthermore, the plan recognizes stormwater runoff problems in the East Roseland area (page 244) . Finally, the DEP Agreement No. G0061 , Attachment A, Page 1 of 9
