Pleasant Hill: Hidden Creek

At the small Hidden Creek subdivision in Pleasant Hill, the usual suburban lawn has been partly replaced by landscaped biofilter “dry ponds” with underdrains. This lets the ponds filter runoff and let it soak into soil while also draining quickly and shunting high flows to storm drains.

Streets also are narrow, with parking in turnouts, reducing the impermeable area (not shown).
