GENERAL LOCATION AND DESCRIPTION A. Location The project area of this report includes the section of North College Avenue (State Highway No. 287) between East Vine Drive and Laporte Street in Fort Collins, Colorado. The surrounding area consists of railroad yards, commercial facilities and vacant land that will soon be developed. This project is in a part of the Northeast one -quarter of Section 11 and the Northwest one -quarter of Section 12, Township 7 North, Range 69 West in Larimer County, Colorado (see Figure 1). All storm drainage currently passes into the Poudre River, which is located near the projects northerly limits.

Description of Project The City of Fort Collins is planning to improve North College Avenue from East Vine Drive south to Laporte Street. The improvements will allow better access to local businesses, increased safety and better traffic movements that can accommodate all modes of travel. The plan consists of four twelve foot lanes, access to businesses, the addition of bicycle and pedestrian facilities and replacing the Cherry, Willow, Maple, and Jefferson intersections with concrete. A new pedestrian trail will connect the east side of North College Avenue to the existing Poudre River trail. Improvements to the Riverside / Mulberry intersection shall be included as a part of the North College Avenue project.

DRAINAGE DESIGN CRITERIA A. Regulations This study complies with the City of Fort Collins Drainage Criteria. It is also in general conformance with Colorado Department of Transportation (CDOT) criteria since North College Avenue is a part of Colorado State Highway No. 287. B. Development Criteria Reference and Constraints The 50 and 100-year flood events currently overtop the College Avenue Bridge. The only portion of this project that will be close to the Poudre River area is the proposed pedestrian trail connection. Parts of this trail are to be located within the Poudre River floodway just downstream (east) of College Avenue. The section located in the floodway will be in a cut condition, the remaining part of the trail lies south, outside of the designated floodway. The City of Fort Collins has designated a 0.1-foot floodway for the Poudre River within the city limits. Section 10-61 (5) of the city code states the following: "Fill. No person shall place any fill in the floodway or product corridor unless it is related to the development of public infrastructure or publicly owned recreational facilities in which case any fill that is placed for such permitted development shall not cause a rise in the base flood elevation." A second option was considered. It placed part of the path fill section within the floodway. This caused a rise in the floodway of 0.4 feet. The option was further refined by cutting adjacent areas in order to compensate for the fill. These cut areas were limited because it was desirable to stay out of the waters of the U.S., protect retaining walls and protect the existing bridge revetment. The floodway increases could not be resolved to the extent that the floodway regulations that the city has adopted would be met. The original plan that located the floodway portions of the path in a cut condition has been adopted. This is in conformance with the city regulations. FELSBURG HOLT & ULLEVIG Page 3 Drainage Study N. College Avenue (SH-287) Improvements C. Hydrological Criteria Design storms for this report are 1.40 inches per hour for the 10-year initial storm and 2.86 inches per hour for the major 100-year storm (2-Hour Intensities = 3.69). The rational method was utilized to calculate peak runoffs. D. Hydraulic Criteria All proposed inlets and roadway storm sewer laterals were sized to pass the 100-year developed flows. This was done because many sections of North College Avenue particularly near the railroad, are very flat and do not have the slopes necessary to pass storm waters. Allowable spreads for roadway encroachment and overtopping per the city drainage manual were determined and incorporated into the design. FELSBURG HOLT & ULLEVIG Page 4 Drainage Study N. College Avenue (SH-287) Improvements III. DRAINAGE FACILITIES DESIGN A. General Concept College Avenue is a major arterial roadway. The minor 10-year storm will not overtop the curb and the flow spread will leave at least one-half of the roadway width free of water in each direction. The major 100-year storm will not inundate buildings and the depth of water at the gutter flowline will not exceed 6 inches. In all cases, the proposed cross drainage culverts will be able to pass the 10 and 100-year flows with out any roadway overtopping. Proposed drainage patterns will remain as close to the historic patterns as possible. B. Specific Details A recent Fort Collins construction project has re -directed upstream flows that originally passed into the North College storm sewer system. The smaller quantity of stormwater lessens the impacts of roadway flooding in the area but does not eliminate the problems entirely. Through recent surveying and video inspection of the existing system, it was determined that the main trunk line along North College is still inadequate. Existing culverts consist of 4 inch to 18 inch clay and reinforced concrete pipes (RCP). A 24 inch corrugated metal pipe (CMP) outfalls at the Poudre River. Rods have been driven through a section of this CMP and parts of the line have adverse slopes in order to miss utilities. At a meeting with the city (reference 7) it was decided to upgrade all of the intersections' inlets and storm sewer laterals. These laterals would then be routed to an existing storm system located east of North College Avenue. This existing outfall system consists of 33" - 48" RCP's that runs from Willow St. and extends northeasterly along the railroad to the Poudre River (figure 2). The original outfall system has been analyzed north of Willow St. It will be adequate to accommodate the remainder of the North College storm waters despite the outfalls poor condition. According to the Lindstone & Anderson drainage evaluation (Reference 8), approximately100 c.f.s passes from the west and concentrates at this existing outfall system. Through our recent discussion with the city, much of these offsite flows (approx. 95 c.f.$) are now collected in the Howes St. Outfall and do not contribute to the College Avenue system. It was also noted that the area northeast of Willow Street has had some ponding problems north of the railroad tracks (Reference 4). This issue is being addressed with an additional area inlet to prevent further problems. According to recent utility pothole information there will be some relocation work required to accommodate the proposed trunk line and laterals. Utility crossings less than 18 inches clearance shall have the proposed storm sewer RCP joints encased 10 feet on either side of the crossing. FELSBURG HOLT & ULLEVIG Page 5 Drainage Study N.

Figure 2- Proposed System WFELSBURG HOLT & ULLEVIG Page 6 Drainage Study N. College Avenue (SH-2&7) Improvements Through recent utility coordination efforts with Len Hilderbrand (PSCO) (Reference 9), it has been determined that the 8 inch high pressure gas main that runs from west of North College Ave. to east of Willow St. should be avoided when construction begins. The gas line would be costly and time consuming to be relocated if it is in conflict with the proposed storm sewer. The minimum clearance between the proposed storm sewer and gas line should be no less than 9 inches. The joints of the proposed storm sewer that are crossing the gas line shall be encased for the conflicting section. IV. CONCLUSIONS A. Compliance With Standards This drainage study complies with the City of Ft. Collins and Colorado Department of Transportation criteria. Major drainage planning studies that would affect this site have been discussed with city staff and are referenced in this report. B. Drainage Concept The plan presented in this report should effectively control damage to personal property from storm runoff and ensure safe passage on the North College Avenue. The intent is to remove and replace curb inlets along the project area and connect them to the proposed storm sewer system which will be improved in the future or with this project. The condition of the existing system has been analyzed and has been determined that the capacity and condition warrants upgrading. Area inlets have been placed in problem areas that have been identified by the city staff. The entire existing system within the project limits not affected by proposed improvements will need to be cleaned. FELSBURG HOLT & ULLEVIG Page 7 Drainage Study N.
