The proposed trail improvements are located between the Art Museum and the Rio Grande Trail and at the Hopkins Street Bike/Pedestrian Bridge. IWe obtained the existing 100-year HEC-2 floodplain computer model input and output for the Roaring Fork River from the City of Aspen. The 100-year floodplain model was then re-created I on our computer using the February 1991 4.6.0 version of the HEC-2 program. We could not match the results of the HEC-2 model on file with the City of Aspen. We believe that this is due to changes in the new version of the HEC-2 program. I Using the re-created model as a base, we then input the proposed Roaring Fork River Trail improvements and determined the effect of these improvements on the 100-year water surface elevation. Using the re-created existing conditions HEC-2 model as a base, the proposed trail Iimprovements do not cause a rise in the 100-year water surface elevation. We have enclosed the final design drawings of the proposed Roaring Fork River Trail prepared by Recreation Engineering & Planning (three 24" x 36" sheets dated June 26 and July 9, 1991), Ifloodplain mapping showing HEC-2 cross section locations (two 11"x 17"sheets), a table entitled "Roaring Fork HEC-2 Model Results", and HEC-2 input and output for the re-created existing conditions model and for the proposed conditions model.

MEMORANDUM AUG G 1 3 199' TO: City Attorney CITY ENG SEER Mark Fuller Aspen Consolidated Sanitation District FROM: Leslie Lamont, Aspen/Pitkin Planning Office RE: Roaring Fork River Trail Stream Margin Review DATE: August 13, 1991 Attached for your review and comments is an application from the City of Aspen Parks Department requesting Stream Margin Review approval for a new trail. Please return your comments to me no later than August 26, 1991. Thanks. July 25, 1991 Ms.Leslie Lamont City of Aspen Planning Dept. 130 S. Galena Aspen, CO 81611 Dear Leslie: Enclosed please find a completed Stream Margin Development Application for the Roaring Fork River Trail. This project is being proposed by the City of Aspen Parks Department through Gary Lacy- the authorized representative for the department. His address is: 485 Arapahoe, Boulder, Colorado 80302; phone number(303) 440-9268. The project is located entirely on City of Aspen property,right-of-way,or easements obtained from the Aspen Sanitation District and Pitkin County. Please see the enclosed drawings describing the project and a local vicinity map locating the project within the City of Aspen. The information on these drawings should satisfy all of the requirements listed in attachments 2 & 3. In general, the following is a brief description of the proposed work: _ • Replacement of the existing Hopkins Street Pedestrian Bridge,including improvements to the approaches. • A new trail along the Roaring Fork River connecting to the existing trail at the Art Museum and the Rio Grande Trail. • A trail underpass under the existing Mill Street Bridge. • A new pedestrian bridge to be located downstream from the Mill Street Bridge. This project is designated on the Aspen Area Parks/Recreation/Open Space/Trails , Plan and is part of the Roaring Fork Greenway Plan. —. Please contact me or Gary Lacy with any questions or if you require further information. If the project is approved,we would like to begin construction in early September.

The proposed replacement of the Hopkins Street pedestrian bridge will not affect the existing 100 year floodplain or floodway. The low chord of the new bridge will be more than 2' above the 100 year flood elevation, reducing the chance of debris blockage. The bridge itself is designed as a "breakaway" bridge which is tethered on one end. In the event of a major flood, it will breakaway and not become debris downstream. b.) The proposed trail from the Art museum to Rio Grande Trail will be at or below existing grade, thereby not affecting the existing floodplain or floodway. The proposed new pedestrian bridge will not affect the existing 100 year floodway or floodplain. The new bridge and approaches will cause a minor constriction in the 100 year floodplain limits. This bridge is engineered so as not to create a blockage during the peak flows and will have a minimum of 2' of clearance above the 100 year flood. It also will be a "breakaway" bridge. 2. All of the trails proposed are on the Aspen Area Parks/Recreation/Open Space/Trails Plan and are dedicated for public use. 3. Recommendations of the Roaring Fork Greenway Plan are included in the project. 4. No vegetation removal or slope grade changes are being made that will produce erosion or sedimentation. A number of disturbed areas will be restored reducing the amount of erosion and sedimentation. All new cut and fill areas will be revegetated. 5. The proposed trails and bridges allow for natural changes in the river to the greatest extent possible. Some areas along the trail will be able to trap urban runoff pollution prior to it flowing into the river. 6. There will be no alteration or relocation of a water course. 7. No water course is being altered or relocated. 8. No state or Federal permits are required due to no work below the normal high water line. „Pet 66ti 312 1 1q i iolUedi A- Cerel To `A- ,9 (CiP 44D w�.
