Stormwater Development Standards regulate the location, design, construction, and maintenance of stormwater facilities applicable to the development of new and replaced impervious surfaces. BACKGROUND The current Stormwater Development Standards, required by the federal Clean Water Act and the City’s municipal stormwater permit, have been in place since July 2006. They are an important element of the City’s multi‐faceted stormwater program aimed at protecting and improving the water quality of Eugene’s receiving streams including Amazon Creek and the Willamette River. The existing code standards reduce pollutants before discharging runoff from the development site to the city’s stormwater system and require applicants to demonstrate their stormwater runoff is discharged to locations that have capacity to convey the flood control storm event. The proposed amendments will further reduce pollutants and mitigate the volume, duration, time of concentration and rate of stormwater runoff to the city stormwater system. Changes to the stormwater development standards are being proposed in response to stricter federal and state water quality regulations which must be implemented by January 1, 2014 as outlined in the City’s municipal stormwater permit. More specifically, the proposed amendments will implement a best management practices (BMP) hierarchy of on‐site stormwater management techniques that emphasize and promote low impact development (LID) and green infrastructure approaches which improve water quality and increase capacity in the city’s stormwater system. Low impact development and green infrastructure approaches emphasize practices that seek to mimic the site’s hydrology before development, thereby reducing negative effects of stormwater runoff on nearby rivers, lakes, streams and wetlands. LID practices use design approaches which promote natural systems for stormwater retention, infiltration and conveyance. Applicants will select stormwater quality facilities from the Stormwater Management Manual based on the following priority order: infiltration, filtration, mechanical treatment.
