The provisions of this chapter are intended to:

A. Set forth standards for managing stormwater runoff from construction and development sites to minimize:

1. Degradation of surface water quality by controlling the scouring and sedimentation of creeks, streams, wetlands, ponds, lakes, and other water bodies.

2. Degradation of groundwater quality.

3. Damage to adjacent and other downstream private properties from erosion or other impacts from stormwater runoff.

4. Damage to city-owned parcels, city roads, rights-of-way, and associated infrastructure.

B. Establish the minimum level of compliance that must be met, and provide standards and procedures for inspection, maintenance, and repair of stormwater facilities in Lacey to help contribute to an effective and functional stormwater system.

C. Control stormwater runoff generated by development, redevelopment, construction sites, or modifications to existing stormwater systems that directly or indirectly discharge to the city stormwater system, in a manner that complies with requirements in the National Pollutant Discharge Elimination System (NPDES) Phase II Municipal Stormwater Permit as issued by the Washington State Department of Ecology (Ecology).

D. Complement site planning activities that minimize:

1. Impervious surfaces area.

2. The loss of native or non-native site vegetation.

3. The generation of stormwater runoff.

E. Make low impact development (LID) the preferred and commonly used approach to site development; to require LID be considered at the site planning stage; and to implement LID BMPs unless they are infeasible.

F. Require that all publicly owned and privately owned stormwater treatment and flow control best management practices (BMPs)/facilities are operated, maintained and repaired in manner that conforms to this chapter.

G. Guide and advise all who conduct inspection, maintenance, or repair of stormwater facilities, and provide the authority for the city to inspect privately owned stormwater treatment and flow control BMPs/facilities.

H. To provide enforcement procedures for ensuring compliance with this chapter. (Ord. 1525 §1 (part), 2017).
