Another drainage plan with hydrology report showing impervious is less than pre-fire in Altadena using satellite tracing.

A drainage plan and hydrology report for an Altadena fire rebuild where the site slopes 11 feet from street to rear. We designed flowlines around the main house and proposed ADU, added plastic lined rain gardens on both sides, and used the hydrology report to show pre-fire impervious was greater tha...

Did we turn around an excavation plan overnight for an Altadena fire rebuild for a contractor to have a sense of the earthwork involved? You should know the answer by now.

Included vertical cut plus trim or horizontal shoring options, along with improved drainage grades in the sections.

We wrapped an AI search box into a static website using Cloudflare Pages and Astro, no traditional server required.

Ask it anything about our civil engineering work: drainage plans in Altadena, hillside grading in Pacific Palisades, hydrology reports, sump pump design. It pulls from our actual project history and blog posts, not generic AI responses.

Also launched a real-time status page tracking all our web properties with actual response times.

See how it works:

We built a status page with real response time metrics and an AI search tool that answers questions about our civil engineering work.

Time to brighten up the feed as we add a couple projects to the portfolio weekly from here on until we get much more to showoff. This Pacific Palisades SFR appears to have survived the fire, a personal favorite one we worked on.

Grading plans, LID report, and excavation plans for a Pacific Palisades residential remodel. 2-story SFR with basement, existing pool remained, LID drainage to lined rain garden.

Our focus has been on Altadena fire-rebuilds so we now have a focused website at

Altadena drainage plans for fire rebuilds. Civil engineers since 2011. Pre-fire vs post-fire hydrology analysis.

Plancheck wanted the plans changed, we pushed back using calcs from the Hydrology report. They pushed back again and used calcs from the Hydrology report to get out of LID covenants.

We took over for another Civil on this lot and removed the Sump Pump as well which initially plancheck also wanted covenants for.

The homeowner can now use that money saved to throw into the house. Contact us if you need help with your plancheck comments for drainage on an Altadena fire-rebuild.

We recently got a drainage plan approved in Altadena without requiring a sump pump or a LID maintenance covenant. Here is the engineering behind why it worked.

Randomly adding projects to our portfolio to show we do work all over LA County over the years. Going to take some time to organize all of this and get lots more in. No one ever tells us when construction is done, so we just move onto the next project and wow some amazing stuff has been built.

B+W Engineering portfolio of civil grading and drainage projects across Los Angeles. 36+ projects including fire rebuild engineering for Altadena, Pacific Palisades & Malibu.

Updating our website pretty heavily, and randomly came across another project that was featured in Dwell. Fascinating portfolio we have built over the years and trying to sprinkle some of these projects into our portfolio page.
