(a) Non-structural Water Quality Practices: Non-structural post construction best management practices include preservation, planning, or procedures that direct development away from water resources or limit creation of impervious surfaces. Practices such as conservation easements, riparian and wetland setbacks, and conservation subdivision design are all non-structural controls.
(1) All non-structural water quality practices must be protected from disturbance through the construction phase of the project.
(2) All non-structural water quality practices must be protected in perpetuity through the use of appropriate legal tools. All easement or conservation areas must appear on the final plat and be disclosed to potential buyers.
(b) Structural Water Quality Practices: Structural post construction best management practices are permanent features constructed to provide treatment of storm water runoff either through storage, filtration, or infiltration.
(1) All structural water quality practices must be established prior to the completion of the project. Structural water quality practices should be made functional once the disturbed areas on site are stabilized. If detention/retention facilities were used for sediment control during development sediments must be removed prior to the basin being used for post construction storm water quality.
(2) Maintenance. The post construction water quality practice must be maintained in perpetuity by those parties identified in the SWPPP or the Storm Water Management Maintenance Agreement.
