Environmental Programs

Minimizing our impact on the environment by living in a responsible and sustainable manner is essential to maintain the unique rural character of our community and to ensure our resiliency into the future.  The City of Rolling Hills works hard in collaboration with partner agencies to protect our local canyon and wetland habitats from erosion, pollution, and wildfire thereby protecting the quality of nearby waterbodies for the benefit of human health and aquatic life.  You can contribute to the environmental health and resiliency of our community and precious natural resources by exploring the links below:

Water Pollution Prevention

When it rains or when excessive water is used on individual properties, the water runs off and drains through our canyons into one of three waterbodies: the Santa Monica Bay, Machado Lake, or LA Harbor.  Runoff from properties can carry pollutants which threaten the water quality and habitats of our canyons, local waterbodies, beaches, and tide pools. The pollution prevention tips below offer ways to help protect these important natural resources.

Measure W (Safe, Clean Water)
In 2018, Los Angeles County voters approved Measure W (Safe Clean Water Municipal Program Funds) to provide funding for stormwater projects and programs to increase local water supply, improve water quality and protect public health.  Funding is provided through a parcel tax of 2.5 cents per square foot of impermeable land area (building, concrete, etc.). The measure provides cities and Los Angeles County with the funds to capture, treat, and recycle storm water.  The city must submit an annual report within six months of the close of each fiscal year describing the use of its Municipal SCW Program Funds. The annual report must describe how the funds were used during the preceding fiscal year and how those uses are eligible expenses that advance the goals of the Safe Clean Water Program

 Opportunities to Get Involved in Watershed Management and Protection Activities

There are many opportunities to participate in local and regional water pollution prevention and water resource management efforts:

Water Conservation

With our region’s dry climate and persistent drought conditions we are all keenly aware of the importance of using water resources wisely.  Each year in Los Angeles County, enough rainwater to meet the needs of 3.5 million people is lost to the ocean.  While there is important work happening at the regional level to conserve water resources, there are important steps you can take in your own back yard to make water conservation a way of life.

Sustainable Gardening and Landscaping

California native, drought tolerant gardens and landscapes are low-maintenance, less water-intensive, prevent water pollution from fertilizer and pesticides, attract pollinators and support native species like the Palos Verdes blue butterfly and the cactus wren.  The links below provide information on creating sustainable, fire-wise landscapes and gardens.

Household Waste Management

Reducing waste, reusing items you might normally throw away, and recycling will save money, energy, and natural resources.


Septic Systems (Onsite Wastewater Treatment Systems)

Los Angeles County Department of Public Health reviews and approves onsite wastewater treatment systems (OWTS) in the City of Rolling Hills through the Local Agency Management Program consistent with the State Water Board’s requirements for siting, design, operation and maintenance of OWTS. The two types of systems approved in Rolling Hills, conventional and non-conventional systems, are explained in the links below along with guides for maintaining these systems so that they function in a manner that will keep our families, community, and environment safe and healthy.

If you have questions or concerns about your OWTS, contact LA County Public Health at:
