Business Water Savings
The State of California adopted Assembly Bill 1881 to promote the conservation and efficient use of water. It requires the prevention of water waste through landscape design elements. In order to comply with California water conservation policy, the City adopted Ordinance No. 627, Water-Efficient Landscaping Regulations.

For additional information and a copy of the City of Commerce Water Efficient Landscape Ordinance Policy Guidelines, contact the Planning Division of the Public Works & Development Services Department at (323) 722-4805, ext. 2810. 

The new Ordinance applies to public and developer installed landscape projects requiring a permit.

Irrigation Requirements
  • Incorporating efficient irrigation design into the landscape design so that the landscape remains within budget,
  • Installing a dedicated landscape meter for landscaped areas over 5,000 square feet, and
  • Installing smart irrigation controllers which can automatically adjust irrigation scheduling based on weather patterns.

Soil Requirements
  • Soil testing so that it can be taken into account when selecting irrigation run-times, and
  • Minimization of compaction and grading to encourage water infiltration.

Implementation, Compliance and Enforcement
Eligible projects must submit a completed Landscape Documentation Packet, which includes:
  • A simple concept drawing of the plant and irrigation design,
  • A plant list, soil plan, and irrigation schedule, and
  • Construction "as-built" drawings reviewed and signed by a landscape architect.

  • A Certificate of Completion must be submitted by the applicant to receive a Certificate of Occupancy.
  • Inspections of projects may occur before, during, and immediately after installation to verify that the project is in compliance.
  • A copy of the completed packet will be given to the water agency. If the site is found to go over their water budget, they will be subject to a water audit.
