(a) Pursuant to Government Code Section 50022.2, Marin Municipal Water District Ordinance No. 430, including amendments and successors thereto, is hereby adopted by reference and shall be in full force and effect within the Town of Tiburon. Said ordinance, and amendments and successors thereto shall be applicable to projects that are subject to the water efficient landscape requirements set forth therein, which projects include, without limitation:

(1) New construction projects with an aggregate landscape area equal to or greater than five hundred square feet requiring a building or landscape permit, plan check or design review; and

(2) Rehabilitated landscape projects with an aggregate landscape area equal to or greater than one thousand square feet requiring a building or landscape permit, plan check or design review; and

(3) Any project with an aggregate landscape area of less than one thousand square feet requiring a building or landscape permit, plan check, or design review shall comply with the performance requirements of the ordinance or conform to the prescriptive measures contained therein.

(b) For the purpose of administering these regulations, the Town of Tiburon hereby designates MMWD, the local water provider, to implement, enforce, and monitor the requirements therein.

(c) Town review of applicable projects shall be processed as follows:

(1) Projects requiring approval of a Site plan and architectural review (a.k.a. design review) permit. When an applicable project is subject to Site Plan & Architectural Review approval pursuant to title IV, chapter 16 of the Tiburon Municipal Code, the landscape and irrigation plans required by and submitted with this permit application shall be designed and prepared to comply with the provisions and requirements of the applicable MMWD regulations adopted by reference herein. The process for application review of applicable projects and compliance with applicable MMWD regulations shall be as follows:

a. The application and plans submitted to BUILDING shall be designed in accordance with the most current MMWD ordinance provisions regarding water efficient landscape;

b. The permit approval shall include a condition or conditions that include the following:

  3. The building permit application must be accompanied by a letter from MMWD approving the landscape and irrigation plans.

  4. If the MMWD-approved plans substantially differ from the town-approved plans, these differences may require additional review through the town's design review permit process and/or a revision to the town's permit.

  5. The applicant is responsible for contacting MMWD for all inspections, approval and sign-off on landscape and irrigation installation. Upon approval, MMWD shall issue a certificate of completion, which must be submitted to the planning division before building permit final sign-off or a certificate of occupancy is issued by the Tiburon Community Development Department.

(2) Projects requiring a Building permit and/or grading permit only. When an applicable project is not subject to a Site plan and architectural review permit but is required to secure a building permit and/or grading permit pursuant to title IV, chapter 13 of the Tiburon Municipal Code, such permit(s) shall not be issued until the applicant has secured, in writing, MMWD approval of the landscape and irrigation plans confirming compliance with the most current MMWD ordinance provisions regarding water efficient landscape.
