The way communities dealt with rain runoff ten or twenty years ago was a lot different than the best management practices of today. Yet, those old criteria persist in the City?s current Drainage Criteria Manual, the document that guides stormwater engineering within Colorado Springs. The City is therefore creating a new Drainage Criteria Manual for the first time in decades.
The new manual takes a comprehensive view. Rather than attempting to just manage flooding, it considers flood conveyance plus sediment control and wildlife habitat. Ironically, the most successful stormwater systems are now known to be those that preserve, or restore, natural drainage way functions. While drainage way preservation has long been a City goal, some City policies have prevented implementation.
Attend a free lunch-n-learn on Sept. 15, 2011 to learn how the proposed changes will better protect these natural systems. Examples include reducing the amount of stormwater leaving a project site and shifting from large, regional detention projects to smaller, sub-regional detention areas.
The lunch-n-learn runs over the noon lunch hour, from 12:11 to 12: 49 p.m., at the City Administration Building, 30 S. Nevada, in Suite 102. Attendees are encouraged to bring and enjoy their lunches during the presentation. Those who come have the opportunity to win a door prize tote bag made from recycled City banners.
Each month, the City Green Team sponsors a lunch-n-learn topic on environmental issues. Questions? Contact City of Colorado Springs Sustainability Coordinator Carrie McCausland, 719-385-CSGN (2746) or firstname.lastname@example.org.
