Going beyond the usual engineering approach to comply with city detention requirements allowed Olsson Associates to come up with an unexpected solution for the Veterinary Teaching Hospital Complex at the Colorado State University (CSU) south campus in Fort Collins.
However, with animal holding and feeding areas on campus and stormwater discharge only one-quarter mile from Spring Creek, our team felt that water quality was truly the most important issue.
A typical approach to complying with detention requirements would have been to perform hydrologic and hydraulic modeling and use the results to recommend the standard amount of detention that would be needed. However, our team looked beyond the initial study results and policy requirements and asked the question, “How do these data apply in the real world?” And in fact, after studying the data, we discovered that the 100-year storm event peak flows from the campus to the creek occurred well before the 100-year peak flows in the creek itself. Therefore, the campus master plan changes had no detrimental effect on the runoff rates basin-wide.
It was gratifying to find a solution for CSU that allowed them to focus their limited resources on water quality instead of unnecessary, additional detention. Call us at 970.461.7733 if we can help provide a creative approach to resolving your infrastructure needs.
