construct the water and sewer main under the County labor contract. On September 21, 1993,. the Board of County Commissioners approved the award -of the Labor Contract (Bid No. 4007) to Driveways, Inc. (See attached minutes). The water service will also provide fire protection to Rio Mar Yachts and all property owners adjacent to the water main. ANALYSIS In order to provide water and sewer service to Rio Mar Yachts, as well as provide fire protection along the utility corridor, 1260 L.F. of 10" diameter water main, 950 L.F. of 4" diameter sewer force main, two fire hydrants and one 2" service will have to be constructed. The estimated cost of the labor to construct the water, sewer and fire protection facilities under the labor contract is $17,499.41 (See attached cost estimate from Driveways, Inc.). The pipe, valves and fittings will be supplied by the County at an estimated cost of $23,572.43. A 1O% material and labor contingency of $4,109.16 was also included in the project cost. In-house engineering, inspection and administrative costs are estimated to be $9,069.00, for a total project cost of $54,250.00. The area to be served includes the armory property plus three (3) commercial parcels. All of the other three (3) parcels are presently vacant. Rio Mar Yachts has entered into a Developer's Agreement (see attached agreement) to pay an assessed contribution of $40,066.31 to construct water and sewer service to their property. This cost is based on the area of the parcels east of the proposed water and sewer main that presently do not have water or sewer service available. The total area of these four parcels is 536,132 sq. ft. The estimated project cost distributed.over the total area results in a square footage assessment of $0.10118776719 per sq. ft. -(see attached assessment computation). The area of the parcel owned by Rio Mar Yachts, Inc., which is used to compute their contribution is 395,960 sq. ft. The area to benefit from the assessment project is displayed on the attached tax map. Presently, all properties to the east of the water main are undeveloped, with the exception of the subject site. Once those properties are developed, the benefitting property owners will be charged on a square foot basis to recover the balance of the construction costs. In the interim, financing will be through the use of impact fee funds. Engineering design services for this project will be by the Department of Utility Services staff. RECOMMENDATION The staff of the Department of Utility Services recommends that the Board of County Commissioners: • Approve the Developer's Agreement with Rio Mar Yachts (which authorizes assessing Rio Mar Yachts $40,066.31). • Authorize the Department of Utility Services to issue purchase orders for material and labor associated with construction of the aforementioned utilities. • Authorize the Department of Utility Services to proceed with design, administration and inspection of the project. 74 AUGUST 20, 1996 BOOK 98 f E 893
