Legislators promoting high-density housing need to meet up with state and local water agencies to hammer out realistic approaches to our changing reality.

Although 41 of California’s 58 counties are in drought conditions, legislators are debating bills, such as Senate Bill 9 and Senate Bill 10, that address the construction of housing to meet the state’s Regional Housing Needs Allocation.

Between 2023 and 2031, the state mandate for the nine-county Bay Area is 441,000 units, representing an expected population increase of 1,102,500. The allocation for Los Angeles County is 1,327,000 housing units to accommodate an expected population increase of 3,317,500.

The state’s propensity to accept the RHNA numbers ignores our drought conditions. Nowhere does the legislation indicate where the additional water for these units will come from, nor does it address impact on infrastructure, such as sewer lines.
