Two Great Speakers Participating on Assembly’s last day! 

PCL’s 2022 California Environmental Assembly will be concluding on Thursday, February 24th. We are thankful for our panelists and audience members for making this year’s Assembly a productive and memorable event! Don’t forget to register today if you would like to still be a part of this event! In addition to attending the next two panels, you will receive a link to a website with recordings of past sessions. Click here to register and click here to view the Assembly program.

Our last two panels will wrap up our conversation on climate change by discussing groundwater management and housing policy. The first panel of the day will address the issue of disappearing aquifers and propose new land management techniques to improve groundwater recharge and provide clean water to communities. The second panel will then address the issue of jurisdiction when it comes to affordable housing and land use authority. We are especially excited to announce that Senator Scott Wiener and Mayor Darrell Steinberg will be participating in this panel to bring their unique perspectives on the issue. Come join us on February 24th for an exciting discussion!

Session Five: Adapting to Climate Change with Innovative Land Use/Water Strategies

February 24th, 9:00 am – 10:30 am

Climate change is making atmospheric rivers more common while increasing the likelihood of droughts, and significantly reducing the holding capacity of the snowpack – a result of rising temperatures. Capturing flood and storm waters for groundwater recharge and storage can be a realistic, least-cost strategy for meeting water storage needs and reducing flood risks.

New technologies and analyses developed by researchers at the University of California at Davis and Stanford University are beginning to be applied to identify specific sites where soil characteristics and hydrogeology allow water to percolate readily from the surface to the aquifer.

Infrastructure and land costs of developing and maintaining recharge sites can be shared among multiple government agencies and nonprofits to provide flood management, clean drinking water, habitat protection, and recreational opportunities. Further benefits can include reduced ground subsidence, protection from groundwater salt intrusion, improved groundwater quality, and expanded access to clean water for underserved communities.

Forward-thinking communities have demonstrated that they can achieve multi-benefits with a single groundwater recharge project, thus increasing the cost-effectiveness of infrastructure investments. Speakers will provide specific examples of identifying and preserving prime recharge locations, developing multi-benefit projects on these sites, and new legislation that funds these efforts.

In his two terms in the Assembly, Dickinson established himself as a particularly effective lawmaker including his outstanding contribution as co-author of the 2014 Sustainable Groundwater Management Act.

Session Eight: Sacramento, City Hall, Communities – Who’s in Charge?

February 24th, 10:45 am – 12:15 pm

The recent adoption of Senate Bills 8, 9 and 10 as on-going and new attempts to address the housing affordability crisis in California are part of a growing tension over state intervention in local housing policy.

Beginning in January, the California Attorney General will have expanded authority to pursue litigation against local governments that are perceived to violate new laws including those designed to speed up regulatory review; to require affordable housing deficient cities to approve specified zoning, design, and affordability standards; to prohibit policies (including those established by initiative) that reduce development density; and to make it easier to build services-oriented navigation centers for the homeless.

In early November, Attorney General Rob Bonta announced a new “Housing Strike Force” to enforce development and tenant rights. In contrast, local interest responses have included: 1) the commencement of signature gathering for a state constitutional amendment to give local land-use decisions precedence over conflicting state law, and 2) litigation initiated by the AIDS Healthcare Foundation challenging the constitutionality of SB 10 as it impacts initiative rights.

Senate Bill 8 is a follow-up to SB 330 adopted as the “Housing Crisis Act of 2019” to help increase residential density; protect existing housing inventory and expedite permit processing. Senate Bill 9, known as the “Duplex Act” allows property owners to split a single-family lot and build an additional dwelling unit. Both lots can have their own ADUs. SB 10 authorizes local governments to rezone parcels up to ten units of residential density for urban infill sites and parcels in transit-rich areas.

Our panelists will discuss state and local land-use powers and the future of local governance; the legality of these new Senate Bills; whether the legislation will actually reduce housing prices and materially help reduce the affordable housing crisis; expected and possible environmental impacts; and potential unintended consequences, including displacement of lower-income residents and other environmental justice impacts.
