Response: The proposed site has been incorporated into the SWMM model, which is included in the ODP Drainage Report. Topic: Floodplain Number: 5 Created: 9/28/2007 [9/28/07] The site is in the FEMA and City of Fort Collins 100-year floodplain and floodway for Dry Creek. It is also in the FEMA 500-year floodplain for the Poudre River. The City's Dry Creek Diversion Project may reduce the floodplain and floodway for this area. However, all applicable floodplain regulations found in Chapter 10 of City Code will apply based on the mapping that is in effect at the time of development. The Poudre River 500-year floodplain will not change as part of the Dry Creek Diversion Project. Therefore, no critical facilities will be allowed within the Poudre 500-year floodplain. At time of PDP submittal a floodplain report should be submitted. A copy of the floodplain report requirements are available upon request. Please show the current FEMA and City floodplain and floodway lines on the plans. Response: Acknowledged. Topic: General Number: 9 Created: 9/28/2007 [9/28/07] The level of this submittal is in general inadequate. The submitted drainage report does not comply with our standards for an ODP. No grading was shown, the narrative does not describe the drainage constraints that had to be met, and does not clearly indicate how these will be achieved. The modeling does not incorporate the proposed development drainage design into the regional City model. Please use the guidance of the previously provided ODP as a model as to what is expected at this level. Response: Acknowledged. Topic: Road Crossings Number: 10 Created: 9/28/2007 The road crossing at International Boulevard will be incorporated into the CLOMR that will be submitted to FEMA by the City, any additional crossings proposed by this development will need to provide their own FEMA submittal showing a no rise condition. Response: Acknowledged. Page 6 [9/28/071 .Please use the latest channel alignment to locate the channel on the plans as per the provided alignment by the City, the alignment shown does not match the current alignment as designed by Ayres and Associates. Response: The channel alignment as provided by Ayres is shown on the ODP Drainage Plan in the ODP Drainage Report. Topic: Drainage Constraints Number: 8 Created: 9/28/2007 [9/28/071 The site should either release at a 2-year historical rate as a default rate as specified in the Dry Creek masterplan. If the release rate chosen is above the 2- year historical rate then the modeling should show that the site does not cause the crossing under the Lincoln bridge to exceed 1240 cfs, in accordance with previous guidance given by the City. Response: As per our recent meeting, we have modeled the capacity of the Masterplan DC3 channel using the HEC-RAS model provided by the City. The model indicates that there is adequate capacity for the developed, un-detained flows from the Airpark site. The master -planned condition provides for the flow reductions needed to manage the ultimate 100-year runoff to a level that is below 1240 cfs at the Lincoln bridge (1219 cfs). Please see the drainage report for more information. In interim conditions, the site can release into the Dry Creek Channel while keeping the flow within the banks of the proposed Dry Creek channel, as upstream improvements are completed, the 1-foot of freeboard in the channel will be achieved. Response: As noted above, the HEC-RAS analysis of the Dry Creek Channel indicates that there will be adequate capacity for the un-detained flows. The current drainage map shows that a significant portion of the site draining to the south toward existing county development. The proposed ODP should show all the site draining back to the proposed Dry Creek Channel including the south portion of Basins E1 through E8. Response: Acknowledged. This is shown with flow arrows on the ODP Drainage Plan and is also reflected in the drainage basin map. The site will need to show that no adverse conditions are caused by this development during interim or ultimate conditions on any neighboring or downstream property. A statement to this effect should be clearly stated and acknowledged in the drainage report. Response: Acknowledged. Topic: Drainage Modeling Number: 6 Created: 9/28/2007 Page 5 / East Mulberry Corridor Plan update process, which will most likely update the master street plan on a vicinity -wide basis. Number: 27 Created: 10/3/2007 [10/3/07] The ODP will need to reflect what is shown on the Master Street Plan — therefore the ODP as shown can not yet be taken to hearing. Response: Based on several meetings with Ward Stanford, Kathleen Bracke, Sheri Langenberger, Pete Wray, and Ted Shepard, where we discussed the project's compliance with the current master street plan, we have come to an agreement that what we are now showing is considered to be compliant therewith. Department: Light & Power Issue Contact: Doug Martine Topic: Electric Utility Number: 1 Created: 9/18/2007 [9/18/07] Electric service will be provided by Ft. Collins Light & Power Utility. The nearest sources of power are the N.W. corner of Timberline & Lincoln and other locations on the E. side of Timberline. The developer will need to coordinate power locations, requirements and electric development charges with Light & Power Engineering (970)221-6700. Response: Acknowledged. Department: PFA Issue Contact: Carie Dann Topic: Fire Number: 3 Created: 9/28/2007 [9/28/07] CONNECTIVITY: Airpark Village shall provide public street connection to the Dry Creek development. Response: Please see the revised drawing that now incorporates this comment. Number: 4 Created: 9/28/2007 [9/28/07] PFA will review conceptual plans at the time structures are proposed. The development shall meet requirements for water supply, emergency vehicle access and addressing. Response: Acknowledged Department: Stormwater-Water-Wastewaterissue Contact: Basil Hamdan Topic: Channel Alignment Number: 7 Created: 9/28/2007 Page 4 [1013/07] Show any proposed pedestrian and bicycle trails, paths or links with a symbol on the plans. This then shows the general alignment of this route and the connections and where it is going and what it links. Response: Please see the revised drawing that now incorporates this comment. Number: 22 Created: 10/3/2007 [10/3/07] Typically the drainage channels are also shown as another symbol across the property — but I defer to stormwater on how they wish this channel to be shown across the property. Response: Please see the revised drawing that now incorporates this comment. Number: 23 Created: 10/3/2007 [10/3/07] An alley would not typically be shown on a ODP level plan — but if you feel some sort of vehicular link is needed along the southern boundary of the property it would be best to identify that with another symbol and indicate that it is to be a x- access/ private drive/ street, but I would not define it as an alley as I doubt it would meet current criteria for a public alley designation — by keeping it more general you are not limiting what this maybe. Response: Please see the revised drawing that now incorporates this comment. Number: 24 Created: 10/3/2007 [10/3/07] What does the 50' flight path mean — what is the area allowed to be and what are the restrictions? Since it is not something the City is asking for or has defined this needs to be spelled out. Response: There are several existing helipads in the adjacent neighborhood. We agreed at the hearings on annexation and zoning to provide a helicopter flight path, which basically means we will have no buildings and if allowed no trees within it. Number: 25 Created: 10/3/2007 [10/3/07] Need to put roadway names on the existing streets adjacent to this site. Response: Please see the revised drawing that now incorporates this comment. Number: 26 Created: 10/3/2007 [10/3/07] The request to amend the master street plan was received - some additional information and more analysis is needed before the City can determine if we agree with and can support this requested change to the Master Street Plan. Response: We are no longer requesting a master street plan amendment at this time. After the approval of the ODP, we anticipate being part of a Master Street Plan Page 3 determined width. They also just need to be labeled with the category of roadway (as defined on the master street plan) such as Arterial or Collector. Any design, cross-section, and width of the roadways will be determined latter when the PDPs for the project are submitted. So do not label the roadway as a Boulevard (that is not a category of street we have) also do not indicate the size or if parking will be along the roadway — those are all things that will be determined with the PDP submittals and reviews. Response: Please see the revised drawing that now incorporates this comment. Number: 17 Created: 10/3/2007 [10/3/07] For the non arterials and collector streets on the plans these can be shown, but is probably best shown only as arrows to indicate connections at these points. This could be arrows leading off of the arterial to show internal roadway connections, or the connections across the drainage channel or connections to the adjacent property. Response: Please see the revised drawing that now incorporates this comment. Number: 18 Created: 10/3/2007 [10/3/07] Need to show the two street connection ties to the Dry Creek Subdivision. They have two public street stubs that this project will need to tie into. Response: Please see the revised drawing that now incorporates this comment. Number: 19 Created: 10/3/2007 [10/3107] Where two roadways cross —just show them as crossing as with the design of the roadway intersection design will be determined at the time of PDP and are not in any way indicated or set with an ODP. Response: Please see the revised drawing that now incorporates this comment. Number: 20 Created: 10/3/2007 [10/3/07] Need to show street connections crossing the drainage channel for any parcels that will be on the north side of the channel and with this connections coming off of the arterial to connect into that system of streets. Tracts 12 and 13 can not just be accessed form the adjacent dry creek development. PFA has already indicated that they want these connections to tie back into the arterial on this property when the adjacent property is developed. That is why it is important to show these connections on the ODP plan and on the buffer plan. Response: Please see the revised drawing that now incorporates this comment.

Response: Acknowledged. Number: 12 Created: 10/1/2007 [10/1/07] The extension of International Blvd. from Timberline to Lincoln is shown as a minor arterial street on the Master Street Plan. Transportation and engineering staff will assess feasibility of the proposed change to a 4-lane arterial street on new boulevard. Response: We are now showing this as just an "arterial," and any attempt to designate it as a 4-lane will not be part of this ODP request, but rather part of a future Master Street Plan/ East Mulberry Corridor Plan update process. Number: 13 Created: 10/1/2007 [10/1/07] The ODP shows International as a collector street. This shall be described as a minor arterial street consistent with the Master Street Plan. Response: We now show International as an "arterial." Number: 14 Created: 10/1/2007 [10/1/07] The regional pedestrian and bike trail alignment adjacent to the Dry Creek Cannel needs to continue south through Tract 1 for future connection under Hwy.14 to Poudre River Trail. Add notation to this effect. Response: The regional trail is now shown and noted as requested. Department: Engineering Issue Contact: Sheri Langenberger Topic: General Number: 15 Created: 10/3/2007 [10/3/07] Need to define what FAR means on the land use break down chart. Response: The term FAR is no longer being used. Number: 16 Created: 10/3/2007 [10/3/07] Only the roadways shown on the Master Street Plan are to be shown as lines on the ODP — show these with a symbol (dashed line, solid line) but not with a Page 1
