California Marine Protection Areas http://www.dfg.ca.gov/mlpa/pdfs/southcoast_isor_040710.pdf
Recommendations for San Diego CONSERVATION (SHORT TERM & LONG TERM) • Implement the Regional Model Landscape Ordinance. • Work with industry stakeholders to establish educational, training and certification programs and compliance standards for landscape professionals. • Work with local nurseries and retailers to promote drought-tolerant landscaping & indoor water savings devices in their stores. • Engage in a consistent and effective public education and outreach campaign on how to achieve indoor and outdoor water conservation. • Promote incentive-based water conservation rebates and implement more aggressive residential tiered water rates to encourage users to save. • Develop a long-term plan to retrofit all government-owned sites (parks, civic centers, government facilities, freeway & roadway rights of way, etc.) with drought-tolerant landscaping and weather-based irrigation controllers. Where replacing landscaping is inconsistent with the intended use (e.g., active parks), consider adjustments to the irrigation schedule, install weatherbased irrigation controllers and remove water-consumptive vegetation where possible. • Through education and incentives, encourage larger water users such as apartment and condominium complexes and commercial and industrial sites to install irrigation technologies like drip and weather-based irrigation controllers and replace water-consumptive vegetation.
