Rocklin, CA Landscaping Rules: Native Plants (2026)

Section 15.28.230(C) sets the revegetation standards that apply once a grading permit is issued in Rocklin. Permanent revegetation or landscaping must begin as soon as practical and, in any case, within twelve months of reaching final grade and utility placement, with land developed in workable increments tied to a single construction season. Acceptable revegetation methods include straw-mulching, hydro-mulching, or planting a seed mixture specified in the city's Improvement Standards, though the city engineer may approve other methods offering equivalent erosion protection. Within that framework, subsection (C)(6) directs that all revegetation and landscaping be timed to suitable growing periods and specifically encourages native plant materials as the means of reducing irrigation demand, tying the native-planting preference directly to the erosion-control purpose of the chapter rather than treating it as a separate aesthetic standard.

The permittee stays responsible for maintaining the vegetative cover on graded slopes until it is well established or the maintenance duty is formally assumed by another party approved by the public works director, per subsection (C)(10). If planted or seeded vegetation fails to establish and provide adequate protection, subsection (C)(9) requires it to be replanted or reseeded. Because this standard lives inside the erosion-control article of the grading chapter, it applies citywide to any site disturbed by grading, not only to landscaped common areas or subdivisions, and ties into the erosion-and-sediment obligations the applicant already carries under Section 15.28.260(D).
