Altadena Fire Rebuild Drainage Plans - Insurance Question
Going through plan checks and getting the current requirements back in a correction, one of the projects had their insurance ask what code LA County is using to require drainage plans on some lots, and not on others.
Going through plan checks and getting the current requirements back in a correction, one of the projects had their insurance ask what code LA County is using to require drainage plans on some lots, and not on others. The answer is located at Los Angeles County Code section 22.130.160.
This question from the insurance company is a good one, and it highlights how the rebuild process is still evolving. The County’s drainage requirements are based on specific topographical and geological conditions, and we are happy to help explain these requirements to all parties involved in the rebuild.
The key factor is whether the lot sits on the North side of the block or is oriented sideways, which affects how stormwater naturally flows across the property. South-facing lots on flat terrain may not require drainage plans, but most Altadena lots have enough slope to trigger the requirement.
LA County has published their recovery FAQ covering drainage requirements and cross-lot drainage options. For specific questions about your Altadena project, contact B+W Engineering.

Altadena first lot since the Eaton Fire, was sold recently on Calaveras Street for $100k above listing. Location and price wise this seems low to me, but also the buyer will have to wait a while before anything can happen.
