Alameda and Fremont Townhouses
Grand Marina Village townhouses (above) face the ship channel between Alameda and Oakland, in a former industrial area. Construction of a segment of Bay Trail was required as part of the redevelopment.
Left, above and below: The green space between the homes and Bay Trail, open to the public and decorated with sea-themed art, also serves to help purify runoff. Right, above and below: Curb cuts channel polluted street runoff into landscaping.
Drainpipes lead rain from roof to below-ground flow-through planters. In these, engineered soil filters pollutants. Some runoff bubbles up for irrigation and inviltrates into ground. Buried drains carry heavy flows to the municipal storm-drain system.
Villa D’Este also has housing facing pedestrian walkways, with garages behind and additional parking on facing street.
Below left, roof and street runoff is partly filtered in below-ground media in utility courtyards. Shrubs will hide equipment as they grow.
Below right, this development also uses tree-well filters. These flow-through planters are buried boxes filled with media engineered to filter runoff and also support plantings. Click for larger images.
