(A) All subdivisions shall have a stormwater management and treatment system in accordance with the Stormwater Management Plan. This system shall be discussed at the pre-application meeting and shall address routing of stormwaters after they leave the subdivision, as well as the available drainage courses or storm sewers in the immediate vicinity of the subdivision.
(B) The design of the stormwater management and treatment system shall be consistent with general and specific concerns and standards of the Comprehensive Development Plan and the drainage control programs of applicable public agencies. Design shall be based on environmentally sound site planning and engineering techniques and in accordance with the city’s Stormwater Drainage Manual.
(C) To maximum degree possible, drainage from subdivisions shall conform to natural contours of land and not disturb pre-existing drainage ways.
(D) Adjacent properties which may be burdened with surface waters should have the effects ameliorated as much as possible peak flow rates out of the subdivision or development shall not exceed pre-development rates.
(E) Design shall use the best available technology to minimize off-site runoff, encourage natural filtration, simulate natural drainage and minimize discharge of pollutants.
(F) No surface or point source water may be channeled into a sanitary sewer system.
(G) Where possible, a subdivision’s drainage system shall coordinate with that of surrounding properties or streets.
(H) The pre-application information should include drainage impacts and shall be discussed with the Building Official and members of the Planning Commission. Storm sewer design shall be in accordance with the city’s Stormwater Drainage Manual.
