Does the institution have a policy, plan, and/or strategies to reduce stormwater runoff from ongoing campus operations? :
A brief description of the institution's stormwater management initiatives:
(BMPs) for each MCM, and Measurable Goals for each BMP." "Storm Water Run-Off: ... projects which add impervious surfaces and storm water run-off must include storm-water control systems that will not increase flow into the University’s (and consequently Salt Lake City’s) storm-water system. Specific retention design requirements for construction projects are provided in Chapter 4 Civil Engineering."--quoted from pg. 15 of the University's Design Standards General Guidlines.
1. All storm drainage design shall be performed by a qualified civil engineer, licensed to perform such work by the State of Utah.
2. Storm drainage calculations and drawings are to be submitted to Campus Design & Construction for review and approval. Submittal shall contain engineer's stamp and dated signature.
3. Storm drainage design shall be performed to comply with the following conditions:
a. Provide on site detention of storm water runoff to detain the 100 year, 24 hour storm, with 0.25 CFS/Acre run-off rate. Show calculations for detention volume requirement.
4. Coordinate all connections to the University storm drainage system with Campus Design & Construction.
5. Minimum pipe size: Minimum pipe size for storm drainage lines shall be 12" diameter.
6. Minimum slope: Minimum slope for storm drainage lines shall be 0.5%.
7. Manhole or cleanout spacing: Maximum distance between manholes or cleanouts shall not be greater than 300 feet.
8. Changes in direction and lateral tie-in's: Manholes, catch basins or cleanouts shall be provided at every change in direction and every lateral tie-in point.
9. Minimum cover: Minimum allowable cover over top of pipe shall be 3'-0" to grade. Campus Design & Construction shall be consulted if minimum cover is not achievable. Special design considerations will be required when minimum cover is not maintained."--quoted from pg. 13 of University's Design Standards Civil Engineering document

Does the institution have a living or vegetated roof?:
A brief description of the institution's living or vegetated roof:
A roof garden is located on the Frederick Albert Sutton building; "An interdisciplinary group of students who participated in a Sustainability Practicum
taught by Drs. William Johnson and Fred Montague is responsible for several of the building’s environmental performance features, including a roof garden"--quoted from the Sutton Building brochure
Does the institution have porous paving?:
A brief description of the institution's porous paving:
Porous paving installations are located at the Sutton Building and the new Utah Museum of Natural History.
Does the institution have retention ponds?:
A brief description of the institution's retention ponds:
The retention pond is behind Building 215 (Guardsman Way).
Does the institution have stone swales?:
A brief description of the institution's stone swales:
Does the institution have vegetated swales?:
A brief description of the institution's vegetated swales:
There is a vegetated swale east of the Humanities Building (#45).
Does the institution employ any other technologies or strategies for stormwater management?:
A brief description of other technologies or strategies for stormwater management employed:
The U employs "StormCepters", in which surface drains redirect stormwater to underground storage chambers where it is then slowly released into the ground.
