Small Development Rain Garden Detail Packet

The City allows certain small developments or infill lots to provide rain gardens on private property to manage stormwater when no stormwater main exists within the right-of-way fronting that particular property.

The square footage of the rain garden should be equivalent to 10% of the total new plus replaced impervious area of the site. There may be additional requirements for sites within a geologic hazard overlay area, Natural Resource Overlay District, with high groundwater or contaminated soils.
