Attendees included Basil Hamdan, Marsha Hilmes, Donald Dustin, Matt Fader and Jack Gianola from the City of Fort Collins; Don Parsons and Robert Van Uffelen from Parsons & Associates, Inc.; George Wingfield from Nolte & Associates, Inc.; and Allan Bliesmer from Hensel -Phelps Construction Company. Discussion centered around the City's comment of the floodplain report, direction of stormwater runoff and water quality needs. The design taken for capture of stormwater includes directing flows subsurface to the LaPorte/Mason intersection storm drain system. The revised drainage report will indicate the storm event captured in further detail. This design is taken in an effort to direct historic flows away from the eastern alley and reduce historic impact. The model indicates no rise in flood water elevation as a result of the proposed Parking Structure. This model carried the water surface profiles to the nearest 0.01 foot. It was determined that we should use an accuracy of 0.1 foot and show no rise, in which case 0.04 foot of rise would be considered "no rise." 3 10 • REPORT OF CONTACT PROJECT: SUBJECT: DATE: CONVERSATION WITH: PRESENT: CC: FENTRESS BRADBURN ARCHITECTS, LTD.

Mark clarified comment #5. The City would like to see the upper floor plans of the building to better understand the relationship of retail to parking, the pedestrian bridge, and the pedestrian walkway in the middle of the parking. Mark felt it would be sufficient to see these plans in the FP submittal. Mark also felt he had a good understanding of the site and his previous request to show site features 150' around the building would not be necessary.

As part of an open parking structure, the stairs are exempt from these restrictions. -There will be a four hour area separation surrounding the retail area. Any doors through this wall wil have to be three hour rated. - There will be a three hour floor/ceiling assembly over the retail area. All joint assemblies in this deck must be three hour as well. - A parapet is not necessary on the fourth level, as far as the building code is concerned, as long as the guardrail conditions are met. Judy Ward SIGNED 9838 REPORT OF CONTACT Page 1 of 1 9-1-98 Q� M@@ P@ urban design, inc. f. Profile has been added. g. Please refer to red -lined plans for additional responses. GENERAL COMMENTS FROM STAFF MEETING 12. Plans have been revised to the extent possible at this time. Further topographic survey is currently underway. These plans are submitted as a Preliminary Development Plan. Notes have been added concerning extended widening to Mountain Avenue. 13. These stairs are required for efficient use of the building, they provide access to the retail from the upper decks, in addition to access to Mountain Street from the upper decks. 14. A rough draft copy of the traffic impact study was submitted September 2"d and is being reviewed by the City presently. 15. Regarding stacking, the parking consultant has determined that the ticket booths cannot be moved far enough into the structure to accommodate all the stacking of the cars. Additionally, moving the ticket booths in further will create internal congestion and block the flow of traffic. Therefore they have accommodated four (4) cars at the LaPorte entrance and six (6) cars at the Mason Street entrances. 16. Under discussion on September 4, 1998, with Stormwater Utility Staff. 17. Please see revised plans. 18. Please see revised plans. 19. This is an existing alley. Captured storm flows from Parking Structure site have been revised to flow to the northwest, as indicated in the revised report and plan. 20. Based upon our September 4, 1998, meeting with Stormwater Utility Staff, no water quality measures are being proposed on -site. 21. Plans have been revised to direct captured flows to the northwest. Specifics of this captured volume will be detailed in the revised drainage report (to follow). 22. There is a covered entrance to the parking structure at the LaPorte/Mason intersection that is anticipated to serve this function. 23. The sidewalk widths have been revised as suggested. Revisions to the plans and plat have been made according to City Staff comments. Please review these revised plans and forward any final comments as soon as possible.

Stormwater Utility (continued) 1. Under discussion on September 4, 1998, with Stormwater Utility Staff. 2. BFE added to plans and note regarding 18". 3. Added profile and revised plans. 4. Please refer to revised drainage report (to follow). 5. The roof drains have been designed for a 100-year flood. If both the roof drains and the overflow drains are clogged, the upper decks will carry 6" of water before the water flows down the light wall. The total car load and standing water load on these floors will not exceed the design maximums. Water will flow down the light wall, build up on the ground floor and exit the structure at the four entrances to the building, (the two vehicular entrances, the Southwest entrance and the loading dock). These four entrances to the building are all at the same elevation, and water will leave these locations at the same time. 6. Please refer to revised drainage report (to follow). From Staff Comment letter: 16. Requested data to follow for further review. 17. Please see revised plans. 18. Please see revised plans. 19. This is an existing alley.

The following changes were made on the plans as follows: SPECIFIC DEPARTMENT COMMENTS Zoning Department a. Ramps are shown at the handicap parking spaces. If there is no ramp shown, there is not a grade change. b. The bicycle racks shown within the property line will accommodate 27 bicycles, the proposal called for 25 racks. c. Evergreen trees would not have enough room in the given space, while the evergreen cover cannot handle the anticipated snow load from snow removal efforts on the street and walkways. d. Typical parking stall dimensions are 9'x 18' for 90-degree parking, 8'-6" x 19'-2" for 75- degree parking, and 8'-6" x 19'-0" for 60-degree parking. Drive aisle widths vary, but a minimum of 24" is maintained for two-way traffic. e. Three bicycle racks, holding five bicycles each are shown adjacent to the retail spaces. f. Snow will not be removed from the upper decks. The snow will be collected and piled on the upper floors by the City. This is how the City handles snow accumulation on other parking structures. The City currently has equipment small enough to move through the parking structures, yet large enough to pile snow. g. Building/envelope dimensions are shown, including relative distances to the property lines. Poudre Fire Authority a. The City's Project Manager is currently obtaining a Mason Street address for this site. A note has been added to the Site Plan indicating basic guidelines for placement and dimensions for address numbers. See attached Report of Contact with Building Official. b. A fire hydrant is being located north of the proposed entrance on the north side of LaPorte. A new fire hydrant is indicated on the east side of Mason. Please see revised plans.
