their own private roads which are accessible to the public. He suggested that perhaps the County could change their bylaws so that something can be done. He urged the Commission to authorize whatever can be done to provide a safe place for people to walk to that area. ST. JOHNS RIVER WATER MANAGEMENT DISTRICT - STORMWATER TREATMENT The Board reviewed the following memo dated 4/19/93: TO: James E. Chandler, p0��N0�1C� County Administrator, ,L FROM: James W. Davis, P.E., !!l��68L95�5, Public Works Directo - SUBJECT: St. Johns River Water Management District Stormwater Treatment Requirements REF. MEMO: Michelle Gentile to James Davis dated April 8, 1993 DATE: April 19, 1993 Prior to SJRWMD regulating stormwater treatment, the County Public Works Department paved as many as twenty roads a year using petition paving and gas tax revenue. Recently, the County Engineering Div. has been required to retain stormwater in road right-of-way retention areas and submit lengthy stormwater permit applications to SJRWMD for a permit. Usually, the application is 40-50 pages of exhibits, calculations, etc. for each project. Some applications take as many as three weeks to develop. As noted in the attached memo, the SJRWMD staff is now indicating that when paving county roads, the county will have to treat at least the runoff from the first 1 of rainfall from not Just right- of-way areas but the entire subdivision area, including houses, yards, etc. The 50'-60' wide right-of-ways do not contain enough surface area to store this runoff. When a significant rainfall occurs, the citizens and property owners call the Public Works Department and complain that street swales are flooded and the water cannot drain out. We explain the State's water quality requirements, but they are not receptive to this explanation. The bottom line regarding this policy is that the petition paving program will suffer another setback. Studies funded by Florida DER have proven that turbidity loading and suspended solids from unpaved road runoff contribute two million pounds of silt in the Indian River in our County. This is a major source of water pollution, covering grass beds and choking aquatic life. I plan to discuss this issue with SJRWMD staff and try to have this policy relaxed. I feel the County Commission should be advised, since such projects as Vero Lake Estates, Floral Park and Ranch Estates may be delayed. Please contact me if you have any questions. 43 APR 2 71993 Boa 89 FnF.319.4
