Increase permeable areas, by leaving highly porous soil and low-lying areas undisturbed; by incorporating landscaping and open space into the project design; by using porous materials for or near driveways and walkways; and by incorporating detention ponds and infiltration pits into the project design;

(2)

Direct runoff to permeable areas, by orienting it away from impermeable areas to swales, berms, green strip filters, gravel beds, and french drains; by installing rain-gutters oriented towards permeable areas; by modifying the grade of the property to divert flow to permeable areas and minimize the amount of stormwater runoff leaving the property; and by designing curbs, berms or other structures such that they do not isolate permeable or landscaped areas;

(3)

Maximize stormwater storage for reuse, by using retention structures, subsurface areas, cisterns, or other structures to store stormwater runoff for reuse or slow release.

(d)

Existing development. Existing development shall control stormwater runoff so as to prevent any deterioration of water quality that would impair subsequent or competing uses of the water. The city manager or designee shall identify the BMPs that may be implemented to prevent such deterioration and shall identify the manner of implementation.
