Summary
Hanford's water-efficient landscape ordinance treats rain gardens and cisterns as encouraged, not mandatory. Hanford Municipal Code § 12.08.170(C) recommends rainwater-capture features for infiltration and onsite storage, but Chapter 12.08 requires no property owner to install one; if you do, your permitted landscape plan has to show it.
A. Stormwater management practices minimize runoff and increase infiltration which recharges groundwater and improves water quality. Implementing stormwater best management practices into the landscape and grading design plans to minimize runoff and to increase onsite retention and infiltration are encouraged. B. Project applicants shall refer to the city or regional water quality control board for information on any applicable stormwater ordinances and stormwater management plans. C. Rain gardens, cisterns and other landscape features and practices that increase rainwater capture and create opportunities for infiltration and/or onsite storage are recommended.
Full Breakdown
08, Water Efficient Landscape Design and Installation (Ord. 020(A). 170, Stormwater management, states that stormwater best management practices 'are encouraged' (subsection A) and that rain gardens, cisterns and similar rainwater-capture and infiltration features 'are recommended' (subsection C); applicants are directed to the city or the regional water quality control board for any separate stormwater ordinances (subsection B). Because the chapter never uses mandatory 'shall' language for rainwater capture itself, no Hanford landscape project is required to include a cistern or rain garden. 050. 020(H) where the project remains in substantial compliance overall.
Violations & Fines
There is no fine for skipping a rain garden or cistern since Chapter 12.08 never requires one. The exposure runs the other way: if your plan includes rainwater-capture features but fails to identify them as § 12.08.090(D)(11) requires, or otherwise doesn't match what's approved, the city can deny your certificate of completion under § 12.08.110(C)(2). Denial triggers a right to reapply or appeal rather than a citation, and the city must tell you how.
