EXECUTIVE SUMMARY This Ordinance unanimously adopted on First Reading on October 18, 2016, authorizes the conveyance to Colorado State University of a permanent stormwater easement on City property at the Gardens on Spring Creek. Colorado State University (CSU) needs to construct a water quality pond to handle the flows from its new construction at CSU, including the new stadium. The Center Outfall Water Quality Pond (Pond) will be constructed on land owned by CSU, as well as on a portion of the City's property at the Gardens on Spring Creek previously identified as the location of a City Water Quality Pond in the 2013 Water Quality Master Plan. The Pond will handle flows from both entities. STAFF RECOMMENDATION Staff recommends adoption of the Ordinance on Second Reading. ATTACHMENTS 1.

EXECUTIVE SUMMARY The purpose of this item is to authorize the conveyance to Colorado State University of a permanent stormwater easement on City property at the Gardens on Spring Creek. Colorado State University (CSU) needs to construct a water quality pond to handle the flows from its new construction at CSU, including the new stadium. The Center Outfall Water Quality Pond (Pond) will be constructed on land owned by CSU, as well as on a portion of the City's property at the Gardens on Spring Creek previously identified as the location of a City Water Quality Pond in the 2013 Water Quality Master Plan. The Pond will handle flows from both entities. STAFF RECOMMENDATION Staff recommends adoption of the Ordinance on First Reading. BACKGROUND / DISCUSSION In 2013, the City’s Water Quality Master Plan was adopted by Council. This Master Plan included the Spring Creek Basin Water Quality Master Plan. The Master Plan included proposed improvements in the CSU Sub- basin including plans for a City Water Quality Pond on Gardens of Spring Creek property. This much smaller facility, identified as the Ropes Course Pond, was planned to manage flows from off campus areas. To more efficiently handle the area flows, staff members from the City and CSU worked together on the design of a larger pond that will accept more flows than if both entities developed smaller ponds. Most of the land area of the Pond will be on CSU land; however the flows being handled by the Pond will be approximately the same in volume for both CSU and the City. Previously the City’s Parks Planning and Development (PPD) had been included in these discussions, but PPD had not communicated with CSU for some time. Staff delayed taking this item to Council to incorporate design considerations for PPD. These changes include:  The spillway has been shortened to 35 feet long and relocated to the southeast area of the pond, which also results in a shorter spillway slope.  Spillway material will be sandstone blocks, stepped down in a pleasing fashion.  The trail spur is reconfigured to move it away from Spring Creek at the southeast portion, and possibly expansion in the southwest triangle.  The length of the trail spur, except for spillway, is above the 100-year base flood elevations ATTACHMENT 1 Agenda Item 8 Item # 8 Page 2  Ten-foot trail and three-foot shoulders with a 3:1 side slopes works with all these changes, and allows the cut and fill in floodway to balance.  The top of the berm where the concrete trail will be built will be graded and seeded in this project. Concrete trail, fence and other trail materials will be constructed as a future project.  Additional landscaping shall be added to the project as shown in Exhibit B to Ordinance No. 113, 2016, to address concerns of screening from Center Avenue and the Spring Creek Trail. CSU will be constructing the Pond and pay the upfront costs, estimated to be between $400,000 and $500,000; CSU will then bill the City for its share. The split of the project cost will be based on flow spillage. The City will reimburse CSU out of a future budget for stream rehabilitation and water quality budget. CSU will perform the necessary maintenance on the Pond. CITY FINANCIAL IMPACTS The total cost of constructing the pond is estimated to be between $400,000 and $500,000. The City will reimburse CSU for 48% of the costs of construction, as approximately 48% of the flows into the pond will be the City’s flows. Working together on the Center Outfall Water Quality Pond is advantageous for both the City and CSU. This combined Pond will handle more flows for the area than if each entity built a smaller pond. If the Center Outfall Water Quality Pond was not being constructed, the City would need to build more water quality ponds, which would require more land and more money. The City’s cost to build its own pond and proprietary mechanical BMP in this area would be approximately $300,000 Due to the benefits being provided by granting this easement to construct the larger Pond, staff does not recommend charging CSU for this easement. BOARD / COMMISSION RECOMMENDATION At its August 24, 2016 meeting, the Parks and Recreation Board voted 8–0 to recommend approval of the easement and found it appropriate to utilize this portion of the City’s land to develop and construct the water quality pond and trail connectivity with the City’s assistance in the design and neighborhood outreach.

Parks and Recreation Board minutes, August 24, 2016 (PDF) -1- ORDINANCE NO. 113, 2016 OF THE COUNCIL OF THE CITY OF FORT COLLINS AUTHORIZING THE CONVEYANCE OF A PERMANENT STORMWATER EASEMENT ON CITY PROPERTY AT THE GARDENS ON SPRING CREEK TO COLORADO STATE UNIVERSITY WHEREAS, the City is the owner of property known as the Gardens on Spring Creek, more particularly described as Tract A, Centre for Advanced Technology 22nd Filing, Community Horticulture Center, Fort Collins, Larimer County, Colorado (the “City Property”); and WHEREAS, the City and Colorado State University (CSU) have been working on the design of water quality pond for the Spring Creek Basin that would be located partially on the City Property and partially on CSU property, and would accept flows from both CSU’s property and other properties in the area (the “Center Outfall Water Quality Pond” or “Pond”); and WHEREAS, the Pond would be more efficient and handle more flows from the area than if the City and CSU built separate ponds; and WHEREAS, in order to construct the Pond, CSU requires an easement on the City Property in the location described and shown on Exhibit “A”, attached and incorporated herein by reference (the “Easement”); and WHEREAS, CSU would be responsible for construction and maintenance of the Pond, and for landscaping the Pond as shown on Exhibit “B”, attached and incorporated herein by reference (the “Landscaping”); and WHEREAS, CSU would pay the upfront costs of construction and the Landscaping, estimated to be between $400,000 and $500,000, with the City reimbursing CSU for 48% of such costs; and WHEREAS, the City’s cost to build its own pond and proprietary mechanical best management practice (BMP) would be approximately $300,000, and the fair market value of the Easement is approximately $2,130; and WHEREAS, because the cost savings to the City from not having to build its own pond exceed the amount the City will pay for construction of the Center Outfall Water Quality Pond and the value of the Easement combined, City staff is recommending that the City not charge CSU for the Easement; and WHEREAS, Section 23-111(a) of the City Code authorizes the City Council to sell, convey or otherwise dispose of any interest in real property owned by the City, provided that the City Council first finds, by ordinance, that such sale or other disposition is in the best interests of the City. -2- NOW, THEREFORE, BE IT ORDAINED BY THE COUNCIL OF THE CITY OF FORT COLLINS as follows: Section 1.
