RECOMMENDATION Staff recommends approval of the Resolution. The Water Board and the Natural Resources Advisory Board recommend approval. FINANCIAL IMPACT The capital cost of all identified improvements in the Master Plan update is $11.8 million. Approximately $5.9 million of that will be built in conjunction with and paid for by development. The remaining$5.9 million will be paid by the City Stormwater Fund with revenue from stormwater rates and development fees. This will not require an increase in rates or significantly affect the 30- year stormwater program build out. EXECUTIVE SUMMARY In 2004, Council adopted the City's Stormwater Master Plan. Since that time, a more detailed analysis has been completed for the portion of the Cooper Slough Basin above the Larimer-Weld Canal (north of Vine Drive). This information provides guidance for storm drainage capital improvements and requirements for developing properties in this part of the basin. City Code allows for stormwater master plans to be updated by the Utilities General Manager. The Utilities General Manager approved the Cooper Slough Master Plan update known as Upper Cooper Slough in August 2007. A major property owner in the basin, Anheuser-Busch Inc, has requested City Council affirm the General Manager's approval. BACKGROUND The City's current Stormwater Master Plan was adopted in 2004. The Master Plan analyzed each stormwater basin's flooding and water quality problems and provides general direction for stormwater management. The Master Plan includes: April 1, 2008 -2- Item No. 17 1. Recommendations for cost effective projects to reduce flood damages to homes and businesses, the potential for the loss of life, as well as, reducing the over topping of roads, railroads and irrigation ditches. 2. Provides guidance for new development. 3. Provides guidance for enhancement to the riparian habitat along stream corridors to improve water quality. 4. Provides guidance for stabilizing streams where necessary. When the City's Stormwater Master Plan was adopted in 2004,the entire Cooper Slough Basin was analyzed; however, detailed information to guide future activities in the basin was only provided below the Larimer-Weld Canal (Lower Cooper Slough). The portion of the Master Plan related to Upper Cooper Slough (above the Larimer-Weld Canal) still needed to be developed. The update has now been completed and an executive summary of that Master Plan is attached. Elements of the Update The upper portion of Cooper Slough basin is sandwiched between the Dry Creek and Boxelder Creek basins and encompasses about 26 square miles. This area is largely outside of the City's Growth Management Area and is farmland with some urbanization taking place. The major elements of the update include a regional detention pond north of the Larimer-Weld Irrigation Canal; an outfall for the portion of the basin west of the No. 8 Outlet Irrigation Ditch; safety, aesthetic and water quality improvements to the No. 8 Outlet Irrigation Ditch; water treatment best management practices to protect the Cooper Slough below the Larimer-Weld Canal; further study to address the stability and lack of vegetative diversity of the lower slough;and various road, irrigation ditch, and railroad crossings. The No. 8 Outlet Irrigation Ditch flows north to south on the west side of the basin. It carries an• es a large g amount of storm runoff and as well its normal irrigation flows. The existing ditch is characterized by unsafe, steep,unsightly and unstable banks,has limited habitat value and contributes negatively to water quality. A plan was developed to improve its safety, expand its habitat value and decrease its impacts on water quality. Impacts on the Lower Cooper Slough Cooper Slough,now located in the County and in the lower portion of the basin,is a valuable natural resource for the area. Cooper Slough has the potential to be impacted by future urbanization. An assessment was performed on Cooper Slough by a consultant specializing in wildlife habitat assessments, to define what the implications might be of future urbanization in the basin. In regard to groundwater flows in the Slough, the report stated as increased urbanization occurs, there will be an increase in groundwater flows. The Slough would remain more in a"warm-water' condition and potentially an increase in more migratory and winter use by waterfowl. However,this increase would be limited due to the poor structural diversity in vegetation along the Slough and narrowness of the water channel. April 1, 2008 -3- Item No. 17 The report did raise a concern that increased surface flows along the Slough could have an effect on the Slough. The report identified the importance of doing Best Management Practices(BMPs), such as cleaning up the surface flows before they reach the Slough or reducing the amount of surface flows would reduce the impact significantly. The design of the large detention ponds above the Larimer-Weld Canal will play an important role in protecting the Slough by the incorporation of water quality treatment in their design. Also, with adoption of the Master Plan, new development in the basin would have to provide on-site BMPs when they develop. The report also recommends that the City continue to study the Slough to address its stability and identify measures to increase the diversity of its vegetation and to continue to monitor the water quality in the Slough. Adoption by the Utilities General Manager Section 26-543 of the City Code allows for updates or enhancements to current master plans to be approved by the Utilities General Manager as long as the updates are for the sole purpose of enhancing the existing master plan and does not diminish the general purpose or specific objectives of the adopted master plan and does not diminish the ability of the plan to address the disposition of stormwater. The Utilities General Manager approved the update to the Cooper Slough Basin in August 2007. Since that time,a major land owner in the basin,Anheuser-Busch Inc,has asked City Council to affirm the General Manager's adoption of the Master Plan update. Public Outreach The development of the update to the Cooper Slough Master Plan was a collaborative effort between the City and Anheuser-Busch Inc. City staff performed one-on-one public outreach with the other property owners in the area,primarily large-tract property owners. The update was reviewed by the City's Water Board,Natural Resources Advisory Board and Planning and Zoning Board. Both the Water Board and Natural Resources Advisory Board took formal action and adopted motions recommending adoption of the update. The Planning and Zoning Board discussed the matter at a work session and did not take formal action on the Master Plan update. ATTACHMENTS I.

See attached figure entitled "Cooper Slough Basin". The majority of the basin is currently farmland with the exception of the Anheuser-Busch brewery site. However, the southern portion of the basin within the Fort Collins Growth Management Area is experiencing rapid urbanization. Stormwater within this basin flows generally from north to south, with runoff ultimately being captured by the Larimer and Weld Canal . During large storm events, runoff spills into the Cooper Slough from the Larimer and Weld Canal . See attached figure entitled "Upper Cooper Slough Study Area, Existing Drainage Patterns". Located on the west side of the basin, the No . 8 Outlet Canal runs north to south and is a primary conveyance of stormwater to the Larimer and Weld Canal. When the capacity of the canal is exceeded, stormwater spills out of the canal to the southeast combining with runoff from the north, ultimately overtopping the Colorado and Southern Railroad and into the Larimer and Weld Canal. The basin hydrology of the basin was studied as part of the Boxelder Creek / Cooper Slough watershed by the City of Fort Collins and Larimer County in 1981 and 2002 . In addition, a drainage master plan was prepared for the portion of the basin owned by Anheuser-Busch, Inc in 1984 in conjunction with development of the brewery site. The 2003 update to the City ' s stormwater master plans adopted improvements for the Lower Cooper Slough Basin and identified the need for the Upper Cooper Slough as an area to be further studied. Basin Problems The master plan identified flood hazards related to the overtopping of roadways and the Colorado and Southern Railroad as well as spills out of the No . 8 Outlet Canal and the Larimer and Weld Canal. During a 100-year storm, the railroad embankment impounds 250 ac-ft of stormwater and overtops by 900 cfs. If nothing is done to address the overtopping of the embankment, there is the potential the embankment could fail and cause damage downstream. While overtopping of roadways and railroads is a significant hazard, the expected new development in the area between County Road 56 and the Larimer and Weld Canal has also raised the need to develop a stormwater master plan for the basin. Currently, the basin has no dedicated outfall channel that would convey runoff from developed lands in the basin to existing waterways . Also, the No . 8 Outlet Canal company has expressed concerns about allowing new development to use the canal for stormwater conveyance without a coordinated plan from the City. Furthermore, no defined channel exists to convey drainage from the north of County Road 56 through the future developments . Cooper Slough Basin I I 1 • I .

All projects in the basin were sized assuming developed land use within the Fort Collins Growth Management Area. See attached figure entitled "Upper Cooper Slough Study Area, Selected Plan Components". The improvements include : • North Poudre #6 spillway modification; • Sod Farm detention storage ; • No. 8 Outlet Canal improvements; • Colorado and Southern Railroad diversion structure; • Anheuser-Busch regional detention pond modification; • Black Hollow outfall channel and Barker detention pond; • Culverts at Vine Drive and Cooper Slough; • Cooper Slough Bed / Bank improvements . In coordination with project on Cooper Slough at State Highway 14, these projects would prevent road and railroad overtopping, eliminate spills from the irrigation canals, provide outfalls to Cooper Slough and Dry Creek, limit the impact of off-site runoff, and mitigate the potential for future flood hazards from new development. The total cost of the improvements is $ 11 . 8 million. Stream Stability and Habitat The selected plan of improvements proposes to convey runoff under the Larimer and Weld Canal directly to Cooper Slough. The additional volume of runoff into the slough could degrade the stability and habitat quality of the slough. Therefore, a series of stabilization and enhancement measures to Cooper Slough are included to mitigate the change in hydrology. New Development Guidance The implementation of the selected plan of improvements is critical to help mitigate the potential for flood damage related to new development. In addition to the improvements, new development is required to detain developed runoff at the 2-year historic release rate. This detention requirement does not apply to land owned by Anheuser-Busch because of the Master Agreement between the City and Anheuser-Busch.

Along with this recommendation, the Board would like to provide the following comment. We will likely never know whether Upper Cooper Slough was once a high quality floodplain; the landscape has been extensively altered through intensive agricultural practices. In contrast, Lower Cooper Slough remains, if not pristine, a unique and moderately high quality wetland in our otherwise and environment. Continuous warm groundwater flows through the slough have made it a magnet for a variety of waterfowl and other aquatic species throughout the year. Given the foreseeable development in the Upper Cooper Slough Urban Growth Area, engineering of its stormwater system needs to progress carefully to protect the distinctive natural values in Lower Cooper Slough. The consultant hired by the City has stated that converting existing farmland runoff to urban runoff, with the concomitant increase in impervious area, will likely increase the frequency, volume and temperature of the discharge into Lower Cooper Slough. Further, they state that even with properly sized residential or industrial detention ponds, any stormwater runoff is likely to yield additional sediment, nitrates and phosphorus, petroleum products, metals, fecal coliform bacteria, oils, soaps, detergents and other products that accompany extensive land use conversions of this type. Because Upper Cooper Slough does not present a clear and present danger in terms of stormwater risks (as for example the Canal Importation Basin), the Water Board urges Council to direct Utility and Natural Resources staff to thoroughly investigate and implement best management practices that are the most appropriate to cost-effectively prevent any degradation to the habitat and water quality values in Lower Cooper Slough. Proper mitigation measures will need to be thoughtfully considered, diligently engineered, and vigilantly monitored. Fixing any problems will cost far more than doing it right the first time. Please feel free to contact me regarding the Board's recommendation on this matter. 700 Wood St. • P.O.

Board Member Johannes Gessler motioned for the Water Board to endorse the Stormwater Master Plan Update as presented on February 28, 2008. Board Member Reagan Waskom seconded the motion and it passed unanimously. Vice Chairperson Gina Janett asked if the Water Board could convey the information from the discussion regarding the importance of ensuring development would not damage the Lower Cooper Slough. Chairperson Yadon asked the maker of the motion or the seconder to incorporate that language into the motion. Chairperson Yadon asked if Board Member John Bartholow would be willing to draft the memo from the Water Board to Council and send it by email to the Water Board for approval. Board Member Bartholow agreed to do so. ATTACHMENT MEMORANDUM FROM THE CITY OF FORT COLLINS NATURAL RESOURCES ADVISORY BOARD DATE: May 28, 2007 TO: Mayor and City Council Members FROM: Ryan M. Staychock on behalf of the Natural Resources Advisory Board SUBJECT: Recommendation pertaining to the Upper Cooper Slough Draft Executive Summary, June 2006 The NRAB recommends that City Council support an "Upper Cooper Slough master plan"that maintains or enhances the Upper Cooper Slough basin in accordance with the most recent version of City Plan. Please feel free to contact me regarding the NRAB's recommendation on this issue. Respectfully Submitted, Ryan M. Staychock, Chair Natural Resources Advisory Board 970-481-1801 ryanstaychock@hotmail.com cc: Darin Atteberry, City Manager John Stokes, Staff Liaison Natural Resources Advisory Board April 18,2007 Page 3 of 5 • Foll 'ng further discussion, Staychock asked Stokes if he sees any critical habitat areas that are b removed from the floodplain. • Stokes 'd he is not aware of any. Most of that land is farmland right now. He said the City owns the d and have conservation easements on some. The idea was to try and preserve a modest co Wor. T'rmnath has been anxious to get that corridor out of the floodP lai regardless o what the City does. They have proposed a separate project to build annel that intercep a flow just west of Natural Resources parcel to divert to the Discussion follow ut financing the project. A lot of the benefits are ou de the UGA so it would make sense th specific property owners pay a larger share than g property owners. A question was asked out the proposed Storm Drainage Authority. i Smith explained that a S Drainage Authority would be formed an 1GA that would direct payment amounts. That an ority would actually build and in ' n it. He replied that elected officials would vote on this. a commented again that they h barely scratched the surface on the financing issue and they not scheduled for Council ime soon. He asked what the Board thinks about the master itself. • Pruessner said she liked that th are including s, etc. • Staychock pointed out an item in a plan that ed confusing: page 17, Table#s-3, Scenario 2: "Fees assessed based all pare in the Boxelder Basin". The body of the document reads "fees being assess n p is actually removed from the flood plain". He felt that didn't match the verbiage in le. • Smith suggested that the Board make tion and he would take it to Council. The Board listed their concerns: N Reso processes, keeping Boxelder Creek in its natural condition,trails, and includ uffer stand • Smith said he would use th ords"maintain an r enhance Boxelder watershed. • Colton commented that y can't be too specific out knowing what's in City plan: They had talked about a bu between communities. He ted that he does share concerns on financing plans but ds like that is coming later. • Pies man sugg at the Board take some time to sett n the language and vote at the next meeting. • Stokes read policies from City Plan that addressed the ard's concerns. • Knowlton d she would like to include what Stokes had r But maybe they should not reference ity plan as Timnath might be opposed. • Smith with Knowlton's suggestion that City Plan not be re cod. He said if the Bo ares their motion next month,he could take it to the oth 'sdictions. • St hock said he will draft the Board's recommendation. Upper Cooper Slough Smith said the master plan was adopted in 2004 which adopted improvements for Lower Cooper Slough from Vine Drive south. He said the area is predominately undeveloped. The ditch company has asked for a master plan to plan for future urbanization. Smith continued stating Natural Resources Advisory Board April 18,2007 Page 4of5 that this is different from the Boxelder Plan because there aren't any structures. The original master plan did not look at Lower Cooper Slough. The ditch companies would like to keep the —� urbanized flows in the ditch but the groundwater in Cooper Slough is still maintained. There are some areas that need stabilization. He said this would be financed primarily by new development. This area is all in the City so the County is not really involved. Following a brief discussion,Piesman suggested they include support of Cooper Slough when the Board drafts a memo regarding the Boxelder Plan. Coun Gosl Recommendations • Stay ck commented that it might be a good opportunity to get some ideas to Council as part o it retreat with new Council members. He said he thought Council would set two year polic oals. He commented that Apt had sent an email with points. He said he would draft ocument to present to council with ideas/recomm ations from the Board. • Colton said he with Apt that they need to be more a ive on policies. He said the Board should en age Council to be more aggressive on able energy policies. At least as aggressive a state is. • Knowlton asked if they uld include a specific goal o olid Waste. • Peterson said he would lik see more aggressive ons to achieve current objectives for solid waste diversion in the of Fort Collins. • Piesman said he agreed with Ap last commen on Glade Reservoir. He would like to suggest the Board recommend that 'ty Coun develop a strategy to maintain or enhance stream flows for the Poudre through C ins in light of developing reservoir projects (i.e. Glade and Halligan). • Piesman commented that Apt had a lot o TA • Knowlton suggested they recommen at Co '1 support RTA alternatives that maximize transit and projects that improve ai uality. Petterson made the following mot' Move that we draft a memo, council with the Boards recomm ations. Liz seconded the motto hich was unanimously approved. Climate Task Fo Selection of NRAB Representative Staychock and P sner expressed an interest in representing the Board on the Climate Task Force. Knowlton nominated Pruessner. Rob seconded the nomination which was unanimous.
