14.7.2 Water Quality Development Ordinances and PolicySeveral water quality guidelines can be implemented at the local level toeffectively control non-point source pollution and point source pollution. Localgovernments have a responsibility to the community to develop sound andpractical policies that will improve the quality of life. The uneducated,uninformed, and unwilling require nudges to comply. Growing and developingcities have an opportunity to guide, plan, and manage growth. Policies andprocedures recommended to provide water quality protection and are not limitedto: Buffer Ordinances Open/ Natural Space Conservation Tree Ordinance Zoning Ordinances BMP Ordinances Stringent OSSF OrdinancesThese water quality ordinances and policy practices can be accomplished throughthe development and implementation of a Master Plan for the City that clearlydefines buffer areas and open space conservation that protects natural areas.Widths of buffers can be based on contributing drainage areas and their locationrelative to a stream centerline. The plan should also define development practicesthrough zoning requirements and provide guidance on tree protection andpreservation.Providing comprehensive site planning and pre-development reviews can ensurecompliance and the review of water quality measures being incorporated into thedesign of the site. The preliminary reviews should demonstrate the technicalelements that support the operation and maintenance of the water qualitymeasures.Klotz Associates Project No. 0972.000.000January 201014-8Caldwell County Regional Water and Wastewater Planning StudyFinal Report
14.8 Structural BMPs for Discharges from Developed LandDischarges from developed land can be managed through the implementation ofstructural BMPs. Structural BMPs that can offset the impact of development onwater quality can include:Infiltration SystemsDetention/ Sedimentation BasinsVegetative Filter StripsVegetative SwalesRiparian BuffersRain GardensA long term operation and maintenance plan should be included in the design andconstruction of the BMPs. Funding and maintenance schedules should also beincluded prior to approval of construction.14.8.1 Infiltration SystemsInfiltration systems are designed to filter out particulates as water percolatesthrough the soil, infiltrating the ground over some area and period of time.Infiltration systems include porous pavement, infiltration basins and trenches.Due to the removal efficiency and potential for migration, this system may not beappropriate over ground water sources.14.8.2 Detention/ Sedimentation BasinsDetention/Sedimentation Basins are utilized to capture storm water and areeffective at removing suspended constituents such as sediment. They can removeup to approximately 80% of suspended solids.Klotz Associates Project No. 0972.000.000January 201014-9Caldwell County Regional Water and Wastewater Planning StudyFinal Report
