Santa Monica is a beachfront city with obvious concerns for water quality.
502 Colorado is a city-owned multi-family housing project that incorporates on site stormwater management to harvest runoff for treatment via infiltration or for reuse in landscape irrigation or indoor flushing. This alleyway was chosen for stormwater management becuase the building takes up most of the parcel, leaving little space for an infiltration zone.
The alleyway includes both porous concrete and Invisible Structures GravelPave to manage overflow from StormTech chambers that is released to the alley surface.
Some of the plastic GravelPave material becomes exposed at turning points from the alleyway into the parking garage of the residential building.
Plastic chambers called Infiltrators or StormTech chambers line the underground storage and are composed of five rows of plastic devices extending the entire lenght and width of the alley.
The overflow pipe allows rainwater to spill onto the gravel and porous surface when the storage chamber reaches full capacity.
Euclid Park includes a depressed area with storage underneath.
This functional landscape also doubles as public parkland.
Visible drains leading to storage tanks underneath.
Downspouts have been disconnected from the building to allow runoff to infiltrate into the vegetated areas.
This Men's Warehouse retrofitted over 50% of the site, requiring that they treat stormwater on site for water quality. They buried a filter box underneath this turf grass area along the road.
On site treatment a this residential site also results in an underground cisterns instead of green infrastructure because of space constraints and aesthetic preference.
A complicated piped system with storage capacity and treatment devices.
The City gives out citations for property owners that create runoff in dry weather conditions through overwatering and other sources.
Parking lot runoff is collected in this drainage area and directed to a bioswale next to the public library.
Santa Monica distributes grants for on site stormwater management. This multifamily housing unit recieved funds for a rain barrel and native landscaping.
The Montana Watershed draings down this major roadway and delivers runoff direclty to the beach. Now includes a large swirl device underground to remove trash, debris and soluble pollutants.
The fenced area includes the outfall to the beach.
This Brake Masters commercial site includes parking lot swales to biofilter stormwater into strip planters fitted with underdrains.
