18A.30.300 Low impact development standards.
A. The proposed site design shall incorporate the use of low impact development (LID) strategies to meet storm water management standards. LID is a set of techniques that mimic natural watershed hydrology by slowing, evaporating/transpiring, and filtering water, which allows water to soak into the ground closer to its source. The design should seek to meet the following objectives:
1. Preservation of natural hydrology.
2. Reduced impervious surfaces.
3. Treatment of storm water in numerous small, decentralized structures.
4. Use of natural topography for drainage ways and storage areas.
5. Preservation of portions of the site in undisturbed, natural conditions.
6. Reduction of the use of piped systems.
B. Whenever possible, site design should use multifunctional open drainage systems such as vegetated swales or filter strips which also help to fulfill landscaping and open space requirements. [Ord. 726 § 2 (Exh. B), 2019.]
