JAN 15 soon 63 F-nGF3?, TO: The Honorable Members of the DATE: January 6, 1986 FILE: Board of County Commissioners THROUGH: Michael Wright, County Administrator FROM: Jams W. Davis, P.E. Public Works Director S U B J ECPTbper„ty Owners Petition Drainage Outfall to Serve Land East of Old Dixie Highway South of 12th Street to South Relief Canal The Public Works Director has been communicating with 36 property owners owning land east of Old Dixie in response ._to.._a _Petition ._to__construct__a drainage outfall to serve approximately 100.54 acres of land. At this time, the property owners of approximately 62% of the land in the watershed area have signed the petition. ALTERNATIVES AND ANALYSIS Many parcels in the 100.54 acres are being considered now for development. Several already developed parcels are experiencing drainage problems resulting in occasional flooding. Two meetings have been held with the property owners to discuss the scope of work for the project. The follow- ing complications are involved. 1) Drainage easements through 10 or 12 parcels must be obtained. The alignment of the easements may change due to the desires of individual Property owners to provide efficient utilization of the individual properties. 2) One existing railroad spur exists which must be transversed. Other property owners are proposing to install future spurs. 3) Many property owners which own land through which the outfall will be located desire to perform excavation of the outfall with their own resources so as to reduce the cost. After these Commitments have been made, the property ownership changes or is under contract and the new owner or buyer is not aware of previous commitments. As a result, the project scope of work is changing. 4) The FEC in June, 1985, considered installing the drainage culvert beneath the Gulfstream Lumber Co. spur. At this time, the FEC can not - do this installation, but is willing to pay their fair share for this part of the work. 5) The Indian River Farms Water Control District's jurisdictional bound- aries do not include this area. The existing drainage patterns, however, direct runoff to the South Relief Canal. Preliminary conver- sations with the Drainage District's attorney, Michael O"Haire indi- cate that since the outfall discharges downstream from any District structures, the impact will not be significant. 6) Since an open grass ditch is proposed and since upstream properties will be required to retain as a minimum the first 1" of rainfall on site, the DER should find no adverse impact to water quality in the receiving waters. _ In summary, trying to meet the individual' and collective needs of 36 Property owners in this area has resulted in changing scope of work, therefore, staff proposes to break the project up into stages as follows: Stage 1 - Obtain all necessary easements. These easements should be dedicated to the County or some maintenance authority. a Stage 2 — Once easements are secured, develop a project cost estimate, scope of work, and assessment roll. Stage 3 - Schedule a public hearing to consider special assessment funding for the project. It is proposed that the property owners be assessed 100% of the cost of the Project, with the County funding the percentage of the watershed area contain- ed in 8th Street and Old Dixie Highway right-of-way. — _ 82
