Roger Buffington Topic: Water/Wastewater Number: 46 Created. 612412008 [6124108] The water mains adjacent to this project do NOT have cathodic protection; therefore, Stda Details 18 and 26 are not needed.

If PVC, add Std Details for tracer wire and locator station. Noted revised to DIP Number. 49 Created: 612412008 [6124108] See redlined plans for other comments. Noted Department. Zoning Issue Contact. Gary Lopez Topic: zoning Number. 44 Created. 611912008 [6119108] No comments. Noted. Please let us know if you have any other issues. Sincerely: Sandy McFeron Project Manager V.F. Ripley Associates, Inc. Gary Odehnal Project Manager Northern Engineering Shepard. Per an email from Doug Martine dated August 9, 2008 the location and clearances are acceptable. Number. 43 Created. 61312008 [613108] Light & Power Engineering will need an electrical 1-line diagram showing both the main building service and the fire sprinkler pump service. Also, will need a Commercial Service (C-1) form completed for each. Noted. Department., PFA Issue Contact., Carie Dann Topic: Fire Number. 45 Created. 612012008 [6120108] PFA has no further comments or concerns at this time. Noted. Department. Stormwater- Water- Wastewaterlssue Contact. Wes Lamarque Topic: Stormwater Number., 40 Created. 212912008 [6124108] There is no discussion in the drainage report whether or not the proposed design is adequate in regard to the 100-year flows in the alley and along Olive Street. Only cross -sections with their proposed water surface elevations were included in the drainage report The text in the Drainage Report needs to discuss this issue. The flows are very close to entering the underground parking garage in the 100-year storm as well as overtopping the stair landing and inundating the stair case along Olive Street. The text in the report needs to evaluate the proposed conditions and make a conclusion whether or not the design is providing a safe situation from flood waters. Drainage report for site was revised, and additional sections were added to alley way and Olive Street. Revisions and calculations are in Drainage report. [2129108] Once the water surface elevation in the alley is determined due to the flows running down Olive Street, a discussion needs to take place to determine if the freeboard is adequate. In our criteria manual for conveyance elements, there needs to be a foot of freeboard to any opening into a building or the conveyance element needs to handle 1.33 times the flow and not enter any opening into the building. With grades as proposed, the foot of free -board could not be met unless a floodgate was installed at the underground parking entrance. Cortina is an example of a project that installed a floodgate. An analysis of the flows in Olive Street with the additional 33% may prove to not enter the underground parking entrance, although a 1-foot tall floodgate would still be recommended. Number. 50 Created., 612412008 [61241081 Please provide erosion control escrow calculations. Erosion control escrow calculations included with re -submittal. Legals and exhibits were forwarded to Marc on July, let us know if you did not receive them. [21261081 The revised design was viewed as being acceptable for City Transportation Staff to grant an encroachment permit. A legal description and exhibit should be prepared for the encroachments on Olive as well as Matthews. A draft of the encroachment permit will then be prepared. Olive Street encroachment exhibits were forwarded in July. [11116107] There's been some general discussion and concern regarding the use of the public space (right-of-way) for aspects the building. Fundamentally, the steps and railings along Matthews along with the planter and low seat wall along Olive are all obstructions of the right-of-way that would need to be approved via an encroachment permit. We're potentially open to the encroachment shown on the Matthews Street side, however we're concerned over the extent of the encroachment onto the public space on the Olive Street side. We're not inclined to introduce a meander in the sidewalk system along Olive Street and would rather just see the sidewalk maintain the consistent 10 foot separation from the curb and gutter. Why is the public space being encroached into? Interestingly, we note page 7 of the traffic impact study which shows perhaps an earlier iteration of the project and has the sidewalk along Olive Street maintain a consistent separation from the street. We would prefer this design over the present iteration and don't see a compelling reason to support the present design. Number.6 Created.1112112007 [6124108] The response letter indicates that the doors are not within right-of-way, though sheet H1 seems to show the doors in right-of-way. Please add after the label "proposed trash enclosure'; "enclosure doors located outside of right-of- way". Noted on Site Plan. [2126108] Are the trash enclosure doors located within the right-of-way? If so, why can't these be outside of the right-of-way? [11121107] The proposed trash enclosure off of the alley cannot have doors which swing out into the alley right-of-way. Either sliding doors or further insetting the trash enclosure would need to be accomplished. Department. Light & Power Issue Contact., Doug Martine Topic: Light & Power Number., 42 Created. 61312008 [6131081 The tentative location for the electric transformer shown at the S.E. corner of the site may or may not work. With the electric loads of the building, plus the load of the now planned fire sprinkler pump, a larger transformer MAY be needed than the proposed site can accommodate. The transformer has been revised. There will be two transformers. Dave Phillips has been coordinating the location and clearance requirements with Doug Martine and Ted B. The transformer pad is too small. Also, Light & Power needs 3 feet of perimeter clearance around the transformer. Noted Department. Engineering Issue Contact. Marc Virata A. The stairs to the parking garage along the alley need a wall or other substantial barrier for the stairwell. Curb head and landing pad elevated per detail B.Remove the sliding gate as it encroaches into the right-of-way. Gate has been removed from right of way. Another "formal" round of review is not needed. Please submit 4 paper copies of the plans for review by City staff. Department. Engineering Topic: Construction Plans Number: 51 Created. 612412008 [6124108] On Sheet H1 please details for the alley. This will report. Noted Issue Contact: Marc Virata remove references to the pavement subgrade be specified at the time of a pavement design Number: 52 Created. 612412008 [6124108] The stairwell leading to the parking garage off the alley should incorporate a wall to provide separation and protection for vehicles/bikes/peds traversing the alley as well as prevent water/snow entering the stairwell area due to snow clearing/street cleaning operations. The wall should be located outside of public right-of-way. Wall / curb line added, see construction plans. Number: 55 Created: 612712008 [6127108] I was recalling that it was suggested that the sidewalk along Olive Street just west of the alley on the north side could appear to swing slightly towards the south as it approached the alley to provide a visual cue to the encroachments along the property. I was recalling that this may have been illustrated on a redline set, which I'm not sure was returned with the submittal. Can a "redirect" in the sidewalk be outlined? Sidewalk at alleyway has been revised. Topic: General Number.2 Created.1111612007 [6124108] The response letter indicated legal descriptions and exhibits have been added. In checking with Cameron, this did not appear to be submitted with the submittal. VIF-RipIGyASSOCIATES INC Landscape ArchiteCtUro Urban Design Planning September 08, 2008 Mr. Ted Shepard Fort Collins Planning Department 281 North College Avenue Fort Collins, CO 80524 ONE LIBRARY PARK - TYPE II Response to staff Project Review comments Dear Mr. Shepard, We have reviewed the staff letter dated June 27, 2008 and have the following comment responses: ITEM: New Four -Story Potential Mixed-Use/Residential Building, 220 East Olive Street COMMENTS: ISSUES: Department: Current Planning Issue Contact: Steve Olt Topic: General Number: 54 Created: 612712008 [6127108] The following comments were expressed at Staff Review on June 23, 2008: Stormwater/Glen Schlueter A. One (1) foot of freeboard is needed for the parking access. Three types of protection are proposed to protect parking garage access. 1) 33% increase in 100yr storm capacity at alleyway, 2) trench drain at entrance and 3) sump pump in garage. These items are detailed in revised drainage report dated July 14, 2008. B. The drainage report needs to be modified and Stormwater needs 1 copy of the revised report Report modified. Department: Light & Power A. The transformer needs to be sized. Transformers sized, shown on plans.
