(BUFFALO RUN) - PRELIMINARY PUD - 36-96A - CORRESPONDENCE - MEETING COMMUNICATIONBuffalo Run Apartments drainage is that a very minor amount of flow (1.66 cfs during the 100-year storm) is draining to the ditch. The flow in the ditch has been stated to be somewhere in the neighborhood of 120 cfs, of which 1.66 cfs is 1.33%. Based on this small 4, flow relative to the ditch flow, the north borrow ditch was discussed as another option. No agreement was reached on the extent of design required to use this option, except to say that it could be as simple as checking which culverts on the north side are causing backwater effeas and determine ifBuffalo Run would be exacerbating the situation, which it most likely would not. Some revisions to the Dry Creek Master Drainage Plan would be required at Final Design for the use of this option. 3. The existing preliminary design shows Buffalo Run drainage flowing in the historic direction through two buildings on the east side of Block Drive. In order to drain this direction, it would be necessary to obtain a drainage easement(s) between these buildings and convey flows to Olive Court from where stormwater flows to the Poudre River along Link Lane. This option was suggested as being a strong first choice, if the property owner would grant an easement for this purpose. The reality of the situation is that the stormwater detention pond for Buffalo Run and the drainage design for Wal-Mart (or equivalent) would remove the threat of flooding for this property owner. With this selling point, the owner would be benefitting from the easement. Glen Schleuter volunteered to meet with the owner of this property to explain the situation, if that would be required. It was suggested that the Buffilo Run developer approach this property owner with this in mind and attempt to acquire this easement. 4. With the option to Olive Street as the strongest approach, but no realistic way to acquire this letter of intent before May 20, stormwater agreed to allow this issue to be suspended until after the preliminary P & Z hearing. As a good engineering approach, however, drainage design will need to be straightened out before any major design begins on the project. 5. The meeting was left with stormwater agreeing to forego this issue until later. Sear -Brown will present the three options in the Preliminary Report. The first option is the drainage easement tying the property to Olive Court. The second option would be the north borrow ditch along Lincoln Avenue. The third option would be the south borrow ditch along Lincoln Avenue. The project has several options for drainage, but to decide upon one requires more research and decision making. The project must achieve a P & Z hearing on June 19, so Stormwater agreed to allow it to pass Preliminary to avoid killing the project, since it is an affordable housing deal.

Meeting Minutes TO: Glen Schleuter, City of Fort Collins Stormwater Utility FROM: Perry E. Cabot PECK SUBJECT: Buffalo Run Apartments Preliminary Submittal DATE: May 16,1997 The following is a summary of items and issues discussed during an informal meeting regarding Buffalo Run Apartments P.U.D. Attendees: Basil Hamden, City of Fort Collins Stormwater Utility Glen Schleuter, City of Fort Collins Stormwater Utility Perry Cabot, SBG Stan Myers, SBG `-- Discussion: l . In order to provide a drainage comeyance from the site, and in response to comments issued fiom City ofFort Collins Stormwater Utility, SRO proposed draining detained flows into the borrow ditch on the south side of Lincoln Avenue. To make this possible, a culvert would need to connect the ditch which "dead ends" at the northeast corner ofthe Buffalo Run site and the ditch which picks up again on the other side ofthe Welding Shop driveway. This culvert would sit in the right-of-way, as verified by Ed Woodward at Latimer County Engineering. Auer spealdng with Ed Woodward and Rex Bums (Latimer County Engineering), draining to this ditch is a worthwhile option because it is in the right-of-way and it is currently being used for other developments' drainage. At the intersection of Airpark Drive and Lincoln Avenue, this ditch once again "dead ends". I mentioned this to Latimer County and they responded by saying that the county has future plans to improve that intersection so that the runoff from all upstream contributors could proceed on down to the Poudre Rive with no blockage. Latimer County could not say for sure when this work would happen. The fact that this south borrow ditch "dead ends" raised some concern in the eyes of Basil and Glen. 2. The option of draining to the north borrow ditch was then resurrected. It was discussed that this borrow ditch could possibly be used and that an extreme analysis may not be needed. It was discussed that what might be required would be some analysis of the backwater causing culverts, but not a corridor analysis of the entire Lincoln Avenue ditch.
