From The Boulder Daily Camera (Anthony Hahn):
Issues surrounding the long-heralded CU Boulder South annexation plans continue to manifest most consistently within concerns over how eventual flood mitigation designs will play out on the property.
Those concerns were clear at a joint meeting between Boulder’s Water Resources Advisory Board and Open Space Board of Trustees on Monday, where dozens of residents from Boulder’s Frasier Meadows retirement community who wore bright orange shirts reading “Save our neighborhoods” and “Stop flooding of South Boulder Creek” urged officials to take quick action on those plans.
Upon annexation of the property by the city, the University of Colorado plans to build more than 1,000 housing units for students and employees, athletic fields and academic buildings on the 308-acre site over the coming decades. It also intends to devote nearly 100 acres of the site to a flood mitigation plan.
The parcel has proven controversial since its purchase in 1996, as neighbors have worried that university’s plans to eventually develop the site would put nearby homes at greater risk from floodwaters.
The chief flood mitigation concept — proposed under the South Boulder Creek Master Plan — includes a flood wall along the south side of U.S. 36 within the Colorado Department of Transportation right-of-way and a dam along the northern portion of the CU South parcel to contain flood waters, according to a staff report presented Monday.
Under this plan, vehicle access to CU South from Table Mesa Drive would be routed to a ramp up and over a portion of the dam. The flood wall would also include an overtopping spillway, which would be designed to discharge floodwaters “that exceed the design storm.”
