Yakima, WA Landscaping Rules: Rainwater Harvesting (2026)

Credit for Rainwater Harvesting Systems. Upon review and approval by the engineer, owners of new or newly constructed commercial/industrial class buildings that utilize a properly constructed and maintained permissive rainwater harvesting system shall be eligible for a ten percent credit applied toward that portion of their stormwater charge arising from the building upon which the system is used. Customers desiring this credit shall apply to the engineer and shall submit engineering design and operational information as deemed necessary by the engineer to make their evaluation and decision. Rainwater harvesting and beneficial reuse of the runoff is found by the city council to both reduce the burden imposed upon the system by the building by reducing runoff and to also have other beneficial water quality effects such as reduced consumption of potable water.

(C) Waiver of Utility Fees for Certain Property. The engineer shall waive stormwater and surface water utility fees for a parcel falling within the following special categories of property upon a showing that the parcel meets the following applicable criteria for so long as the criteria are met:
