French Drain Installation questions from French Valley customers
- Can a French drain here end in a dry well instead of running to an outlet?
- Often it cannot. Monserate sandy loam, mapped through the French Valley area, has a silica-cemented duripan starting near 28 inches, and Friant and Lodo soils on the surrounding hills reach hard rock at 6 to 20 and 4 to 20 inches. The flood district's LID handbook requires an infiltration facility to sit five feet above bedrock or any impermeable layer and ten feet above historic high groundwater.
- Where can a French drain legally let water go on a lot in French Valley?
- County grading notes state that drainage across property lines shall not exceed that which existed prior to grading, that excess or concentrated drainage shall be contained on site, and that no obstruction of natural water courses is permitted. That last point has teeth locally: Warm Springs, Tucalota and Santa Gertrudis Creeks all cross this area and drain toward Murrieta Creek.
- How deep can a trench go before it hits rock on the higher ground east of the valley?
- It varies by map unit within a short distance. Friant fine sandy loam, the most frequently mapped unit in the French Valley area, is described with 6 to 20 inches to a lithic contact on slopes of 9 to 75 percent. Lodo runs 4 to 20 inches, Las Posas 20 to 40 inches to a paralithic contact, and Escondido 20 to 42 inches to hard metamorphic rock.
- What should I have ready before asking about a French drain in French Valley?
- Where the water collects and how long it stays, whether the ground cracks in summer and holds water in winter, whether the lot is on higher ground east of the valley, and where any downspouts end. Photos taken during or just after a rain help. The two things that most change the answer are the soil under the lot and where the water is allowed to go.
- Do newer French Valley homes still need drainage work?
- Often yes. The Census Bureau's 2020 to 2024 estimates, as used on this site's French Valley pages, put 5,300 of French Valley's 12,000 housing units in 2000 to 2009, 4,163 in 2010 to 2019 and 1,355 in 2020 or later. A new tract was graded to a plan, but fill settles, yards get rebuilt and the original fall can be defeated, which is reasoning and not a finding about any street.
