Summary
Moorpark water service is provided by the Ventura County Waterworks District No. 1. Outdoor watering is limited to specific days and prohibited during the heat of the day. Runoff from irrigation onto sidewalks and streets is prohibited. Drought restrictions may impose additional limits during declared water emergencies.
About 40% of the water Californians use at home is used outdoors. Large water savings can be gained by efficient landscape design, installation, management, and maintenance. ... New development and retrofitted landscape water efficiency standards are governed by the Model Water Efficient Landscape Ordinance (MWELO). The MWELO is also referenced by Title 24, Part 11, Chapters 4 and 5 CalGreen Building Code. All local agencies must adopt, implement, and enforce the MWELO or a local Water Efficient Landscape Ordinance (WELO) that is at least as effective as the MWELO. Usually, local agencies that adopt WELOs create a more stringent ordinance than MWELO.
