Objective 9.4.2. - Major Public Facilities Design and Maintenance.

Establish criteria with which to identify, construct or reconstruct major drainage facilities which will be maintained by Manatee County according to a regular schedule to:

• Control flooding and runoff quantity;

• Provide for water quality treatment for runoff; and

• Ensure cost effective drainage control.

Policy 9.4.2.1. Require that stormwater management planning and construction of capital improvements coincide with and provide adequate drainageways, water quality treatment, stormwater collection and distribution systems, and stormwater reuse systems, to adequately address growth and development.

Policy 9.4.2.2. Modify existing deep, steeply-sided drainage ditches into swale-type drainageways, where adequate right-of-way and maintenance easements can be acquired to accommodate such modifications. Also, construct all new public drainageways using swaled, rather than steep-sided, cross sections in areas where right-of-way acquisition financially feasible.

Policy 9.4.2.3. Improve the appearance of major drainage facilities by adequate mowing and landscaping in highly visible locations.

Implementation Mechanism:

(a)

Capital and operating expenditures subject to the availability of funding from a Stormwater Management Fee, or from other sources, to achieve compliance with this policy.

Policy 9.4.2.4. Improve wildlife habitat and supplement natural systems by including, where appropriate, and where feasible, the development of artificial wetland systems within the design of public stormwater siltation/ detention basins.

Implementation Mechanism:

(a)

Compliance with this policy during project design, where appropriate.

Policy 9.4.2.5. Continue to coordinate with the Southwest Florida Water Management District's S.W.I.M. Program when developing local stormwater programs. Local and regional needs shall be considered when funding stormwater related improvements.

Policy 9.4.2.6. Maintain consistency with SWFWMD Environmental Resource Permits to ensure that public and private stormwater management facilities continue to avoid dewatering of and provide recharge of the surficial aquifer.

Policy 9.4.2.7. [Reserved]

Policy 9.4.2.8. Continue the Watershed Management Programs in those basins listed in the Basin Prioritization Study in order to establish basin specific review criteria for stormwater systems. Elements of these criteria shall include, but not be limited to, stormwater hydrology, surface water hydrology, groundwater hydrology, stormwater management systems, stormwater reuse, groundwater recharge, Basin Management Action Plans, water quality and pollutant removal which shall be considered in review and approval of any stormwater management plan as appropriate based on the size and nature of the project.

Implementation Mechanism:

(a)

Implement individual basin studies to identify improvements and land acquisitions, as needed, to implement this objective.

(b)

Identify appropriate pollutant reduction goals for each basin.

(c)

Re-evaluate, at least annually, current stormwater policies, goals and objectives to comply with changes in regulations and standards.
