Climate Action Resilience Plan

DRAFT Climate Action & Resilience Plan is now available for public review and comment. We would love to get your feedback! Please feel free to email Lorenzo Siemann, the principal author of the CARP with any comments, edits or questions about the CARP. He can be reached via email at The plan is to take this to City Council for approval on May 12, 2020. If you are hoping to have any comments considered for inclusion, please submit them by end of business on April 23, 2020. Additionally, there will be the opportunity to comment at the City Council meeting on May 12th.

Terms and Concepts for the CARP

The City of Antioch is creating a Climate Action Resilience Plan (CARP) to address problems related to a changing climate.
The 2020 Climate Action Resilience Plan will be an update to the 2011 Community Climate Action Plan (CCAP), which highlighted strategies that reduce Antioch’s greenhouse gas emissions. Because our community is beginning to see the effects of climate change and will continue to see more changes in the coming years, the City has decided to add resilience (responding to climate challenges) into the planning process. This could mean anything from increasing energy efficiency in homes facing higher temperatures to providing safe and secure transportation in the case of a flood, earthquake, or other emergency.  Since some of the concepts being considered are not widespread, an introduction to them is below.

Green Infrastructure

Green infrastructure is a way to design public areas that use plants and other natural processes to manage stormwater. It can also reduce community energy use, improve aesthetics, and result in cleaner air. To see what other cities in Contra Costa County are doing, visit
Some other examples of green infrastructure include:

  • Green roofs are roofs on buildings that are covered in plant life. Green roofs cool buildings by storing heat energy. Plants and soil also store carbon and clean the air around them. More detailed information on green roofs can be found here.
  • Parks and trees provide shade for the public, reduce the Urban Heat Island (UHI) effect, (UHI: find out more here) and help clean the air.
  • Urban Farming means growing food in residential and/or commercial spaces. Community and residential gardens are examples of urban agriculture. Learn more about urban farming here.

Cooling Strategies and Technologies

As average temperatures in Antioch increase, cooling down our communities will become more and more important. Below are strategies and technologies that can reduce temperatures in our communities.

  • Cool pavements are pavement materials that absorb less heat and stay cooler in the sun. They reduce the Urban Heat Island effect, which is largely fueled by materials that absorb and release heat, such as asphalt. Pavements that are lighter colored or made of materials that reflect heat energy. More information on cool pavements can be found here.
  • Reflective roofs are similar to reflective pavements. However, because they do not need to support heavy traffic, higher reflectivity can be achieved. More info on cool roofs can be found here.
  •  Solar Panel Canopies are a type solar panel infrastructure that also provides shade. You may have seen them in the Lone Tree Golf Course and school parking lots!

  • Cooling centers are places open to the public that allow people to cool down on hot days. Examples of cooling centers parks and swimming pools, as well as other publically open that provide air conditioning, such as libraries, government buildings, and shopping centers.


Energy demand and energy use is expected to increase in Antioch in the coming years. Additionally, more Public Safety Power Shutoffs (PSPS) are expected as fire risk increases. Below are strategies that may help make our energy systems stronger and help transition to cleaner energy.

  • A Microgrid is a localized electric grid that can operate connected to the centralized electric grid (macrogrid) or separate from the centralized electric grid. More information on microgrids can be found here.
  • Community Choice Aggregation (CCA) supports more local control over electricity sources and more potential access to clean energy sources. Power is obtained from an alternative supplier, but transmission and distribution service remains in the hands of the existing utility provider. More information on CCA’s can be found here.
  • A Home Energy Audit is an assessment of your home to understand your energy costs. After the audit, the auditor suggests ways that you can upgrade the energy efficiency in your home.
