As the Civil Engineering industry evolves, the Civil Engineer must evolve with the code and regulation changes.
We went to a new job site in Redondo Beach to discuss the lot for two new houses that will overlook the ocean. While talking to the developer we went over a few different stormwater mitigation measures that are starting to pop up in Los Angeles County. The South Bay beach cities are a bit different than Los Angeles City standards, but the general idea is the same. Infiltrate and clean stormwater when possible. Now that the new Los Angeles City codes (LID/SUSMP) are starting to trickle down into other cities I went to Redondo Beach Building and Safety to clarify what they would need for a grading plan or drainage plan.
After speaking with a Redondo Beach City Engineering, the Civil Engineering involved for handling stormwater depends on where the site is located. Turns out our site falls where we don’t need to do any stormwater cleaning or infiltration. That was great news. But what about another project that will be starting up in a month or so that is a commercial complex? I was given the new standards and these new standards basically follow the new Los Angeles City LID requirements. We must infiltrate when possible. If infiltration is not feasible, then there are some other methods to contain a certain volume of stormwater on site.
This new method of handling stormwater is not exactly new. But the cities in Los Angeles are starting to adopt the new measures. Even though this can make designing a site a little more tricky, this is good for the environment to help sustain Southern California just a little bit longer.
