316.006 Jurisdiction.--Jurisdiction to control traffic is vested as follows:
(3) (b) A county may exercise jurisdiction over any private road or roads, or over any limited access road or roads owned or controlled by a special district, located in the unincorporated area within its boundaries if the county and party or parties owning or controlling such road or roads provide, by written agreement approved by the governing body of the county, for county traffic control jurisdiction over the road or roads encompassed by such agreement. Pursuant thereto:
1. Provision for reimbursement for actual costs of traffic control and enforcement and for liability insurance and indemnification by the party or parties, and such other terms as are mutually agreeable, may be included in such an agreement.
2. Prior to entering into an agreement which provides for enforcement of the traffic laws of the state over a private road or roads, or over any limited access road or roads owned or controlled by a special district, the governing body of the county shall consult with the sheriff. No such agreement shall take effect prior to October 1, the beginning of the county fiscal year, unless this requirement is waived in writing by the sheriff.
3. The exercise of jurisdiction provided for herein shall be in addition to jurisdictional authority presently exercised by counties under law, and nothing in this paragraph shall be construed to limit or remove any such jurisdictional authority.
4. Any such agreement may provide for the installation of multiparty stop signs by the parties controlling the roads covered by the agreement if a determination is made by such parties that the signage will enhance traffic safety. Multiparty stop signs must conform to the manual and specifications of the Department of Transportation; however, minimum traffic volumes may not be required for the installation of such signage. Enforcement for the signs shall be as provided in s. 316.123.
