Which of the following best describes the institution’s approach to rainwater management?:
A brief description of the institution’s green infrastructure and LID practices:
CSU requires stormwater treatment using Green Infrastructure (GI) or Low Impact Development (LID) practices on all projects, new and redevelopment, that create or redevelop more than 1,000 square feet of new impervious area. Projects to which this applies include buildings, building additions, parking lots, and roads.
Stormwater management is integrated into the design of CSU's campuses, including bioswales, porous pavers, constructed wetlands, rain gardens, and retention ponds. Stormwater treatment is a requirement on campus. At the time of this submission, CSU owns and maintains 77 discrete stormwater control measures (SCMs) designed to treat stormwater, and more than 50 porous paving bicycle parking areas.
A copy of the institution’s rainwater management policy, plan, and/or guidelines:
A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
CSU’s requirements are codified in the “Colorado State University Facilities Planning, Design and Construction Standards”, which are maintained online and issued with the contract for each project. The requirements for stormwater treatment are in “Part IV – Regulatory Requirements”. Part 33 40 00, C requires treatment of 100 percent of a project’s impervious area using LID. The requirement for stormwater treatment is not optional, rather it is mandated, and is substantiated by CSU’s Stormwater MS4 permit and an agreement in place with the City of Fort Collins.
CSU’s Facilities Management department maintains a website that includes maps of the SCM locations: https://www.fm.colostate.edu/stormwater (labeled as BMP maps on the website). The department also has an active Stormwater Strategy Team made up of the Environmental Engineer, Grounds Supervisor, University Planner, University Landscape Architect, and Utilities Group representatives. The team meets every three months to discuss new projects and advances in LID and GI concepts and maintenance.
A few of CSU's stormwater management practices include:
- Watching for and correcting "illicit" discharges (for example outdoor washing of equipment)
- Affixing "NO DUMPING, DRAINS TO RIVER" stickers on storm drains
- Annual training of Facilities personnel
- Designing and constructing stormwater quality improvement structures, such as bioswales, buffer filter strips, berms
- Routine cleaning of catch basins and storm drain pipes
- Routine horse manure management
- Monthly inspections by a CSU stormwater inspector
- Rapid spill response
- Collaboration with engineering professors and students on stormwater quality
- Annual report to State regulators
- Compiling & following standard operating procedures for stormwater pollution prevention
