HomeMy WebLinkAboutPVH HARMONY CAMPUS (PHASE 1) - PDP - 32-98A - CORRESPONDENCE -comments from the previous page: No curb return profiles were provided. Please provide profiles of the north and south edges of the medians as well as flowline/edge of asphalt profiles. Please provide full cross sections of Timberline Road. Include cross slopes, flowline elevations, ROW limits, medians, major utility crossings, etc. �k The median in Timberline Road will need to be designed to allow for pedestrian refuge. Hence, it needs to be pulled into the crosswalk. Please include the appropriate side slopes as stated in the SHAC. This includes, beginning at the edge of asphalt, a 6:1 slope for 12 feet, 4:1 slope for 6 feet, and no steeper than 3:1 slope thereafter. Please provide a preliminary design of Harmony Road 1000 feet beyond the construction limits. You will need to show interim and ultimate improvements. The design of Harmony will need to meet the requirements stated in the new State Highway Access Code. You will need to acquire offsite easements and possibly ROW for the improvements to the Harmony Road/Timberline Road intersection. Please show interim and ultimate improvements to Harmony Road. I would suggest having two different sheets (1 for the interim/short range improvements and another sheet for the long range/ultimate improvements). Please provide profiles of the north and south edges of the medians as well as flowline/edge of asphalt profiles. Please provide full cross sections Harmony Road. Include cross slopes, flowline/EOA elevations, ROW limits, medians, major utility crossings, etc. DATE: December 10, 1998 TO: Engineering PROJECT: #32-98A Poudre Valley Health Systems - Harmony Campus - Type II (LUC) - PDP All comments must be received by Bob Blanchard no later than the staff review meeting: 3 c' Wednesday, December*, 1998 ❑ No Comment Problems or Concerns (see below or attached) Note: These are the major items throughout the utility plans.

Please provide cross -sections of both spillways in the plans that include all dimensions and other information. RESPONSE: Erosion/Sediment Control Comments 1. All previous comments have been addressed, plan is OK. Thanks. Please refer to the redlined plans and report for additional review comments pvhhc-3.doc 9. Please clarify the boundary between sub -basins 3 and 32 (which appears to be missing). RESPONSE: 10. Some of the flows along Harmony Road still need to be considered, specifically from sub -basin 2. Has the amount of flow to the irrigation ditch changed? Why not direct the flows from Hannony Road to Pond 393 via inlets and storm sewers? Please address these concerns. In addition, CDOT and the ditch company will need to approve of any changes in this area. Please provide approval letters from them. RESPONSE: 11. The spillway for Pond 393 is currently positioned to flow into a field. Please explain the reasoning for this alignment or place the spillway to flow directly into the outflow swale. In addition, please show the spillway and top of berm elevations on the grading plans to designate the location. RESPONSE: 12. Please provide detailed grading exhibits for Pond 394 and Swale B8 in the grading plans. Be sure to include the pond spillway and top of berm elevations to designate the spillway location. RESPONSE: 13. The City of Fort Collins no longer maintains the benchmarks used at the site. Please use one of the current City vertical control benchmarks to tie-in the site elevations. RESPONSE: 14. The equalization pipe for Pond 393 is a concern. Has the potential for delay effects from the equalization been examined? An EXTRAN analysis in conjunction with the SWMM analysis would clarify this concern. Please indicate with calculations and documentation that the size of the equalization pipe is sufficient. This is a repeat comment. RESPONSE: pvhhc-3.doc 3. Please use the revised rating curve for pond 393 in all the SWMM analyses. In addition, please revise the rainfall hyetograph used for the 10-year SWMM analysis (see page 64 of the redline report). Please double check and make sure that the SWMM rating curves for ponds 393 and 394 are complete and accurately reflect the values calculated. RESPONSE: 4. There are several discrepancies noted in the UDSEWER analysis of storm sewer profiles A & B. Please revise these values and clarify as needed. One important issue is in regards to profile B — The design flow at manhole #3 (60.3 cfs) only accounts for sub -basins 1, 15, & 18. It does not seem to account for basins 12 & 14 (14.8 cfs) which also contribute flows at manhole #3. RESPONSE: 5. The ground surface elevations for storm sewer profile A & I on the plans do not seem to match those used in the UDSEWER analysis. Please clarify. RESPONSE: 6. Please include some of the F1owMaster results that were obtained for tailwater elevation estimates in the rating curve calculations for both ponds. RESPONSE: 7. The riprap calculations are confusing. Please show how (with an equation) the d50 value was obtained for each calculation. Also, please explain why the method used does not finish with that method's sizing technique (i.e., Class 6 instead of Type L). RESPONSE: 8. On the drainage plan, please provide cross -sections of the detention pond emergency overflow spillways with dimensions/elevations indicated, and also indicate the spillway elevation and top of berm elevations on the grading plan.

Sincerely, 1 Robert E. Blanchard, AICP Current Planning Director Poudre Fire Authority a. Fire apparatus access roads shall be provided for every facility, building or portion of a building hereafter constructed or moved into or within the jurisdiction when any portion of the facility or any portion of an exterior wall of the first story of the building is located more than 150 feet from fire apparatus access as measured by an approved route around the exterior of the building or facility. This fire lane shall be visible by painting and signage, and maintained unobstructed. A fire lane plan shall be submitted for approval prior to installation. Any building not meeting theis criteria shall be fire sprinklered. Note: Timberwood Drive shall be established and in place prior to issuance of certificate of occupancy for any structure built. b. Fire hydrants are required with a maximum spacing of 600 feet along an approved roadway. Each hydrant must be capable of delivering 1000 gallons of water per minute at a residual pressure of 20 psi. Hydrants shall be of an approved type'as defined by the water department and fire department. No commercial building can be greater than 300 feet from a fire hydrant. C. Address numerals shall be visible from the street fronting the property and posted with a minimum of 6 inch numerals on a contrasting background (Bronze numerals on brown brick is not acceptable). The MOB shall be addressed separately from the A.CC d. Proposed buildings shall be fire sprinkled. The use of the MOB is totally different from the use of the ACC. Therefore, an area separation wall will be required between these two uses so that the different populations using these buildings will be influenced as separate populations upon the buildings going into alarm condition. This completes the review comments at this time. Additional comments may be forthcoming as the various departments and reviewing agencies continue to h. Typically, a sanitary sewer service is no larger than 6-inch. Is a 10 inch sanitary sewer service needed? i. A 4-foot minimum cover is required over all sanitary sewer mains and services. j. Provide a separate detail for each water main lowering showing the following information: Elevations of water main at beginning, lowered and ending positions. Elevation of item being crossed (i.e. storm sewer, sanitary sewer, etc.). • Define which is a gravity block and which is a thrust block. k. Show vaults for each Air Relief Valve in profile view. Reconfigure 12-inch water main profiles in order to eliminate all unnecessary Air Relief Valves and bends when possible. I. Place one valve between each fire hydrant. M. Show water mains and services in storm sewer profiles. Provide a minimum of 18 inches of vertical separation between water mains and all other utilities in profile views. Indicate concrete joint encasement on larger storm sewer crossings. n. Provide joint encasement detail on detail sheet. o. See site, landscape and utility plans for other comments. p. In response to the request to increase the berm height along Harmony Road — It is our understanding that the Planner/Landscape Architect has requested that the height of the berm above the water main be increased to 3 feet in a few areas. We can allow this increase provided it is limited to "a few areas." Please provide information defining the extent of these areas. Streets a. Concerns remain about the timing of the construction of Timberwood Drive and Snow Mesa Street. These need to be constructed with this phase to provide connections to the Wildwood development to the east and the Timber Creek PUD to the south. that all rooftop mechanical equipment be screened from public view by integrating it into the building and roof design to the maximum extent feasible. The proposed screening clearly appears as an add -on. The screening should be integrated into the overall design theme and architecture of the building. Please refer to Section 3.5.1(J)(2) of the Land Use Code where it states that "...no attention is (to be) attracted to the functions by use of screening materials that are different from or inferior to the principal materials of the building and landscape." Transportation Planning Transportation comments are attached along with redlined plans. Stormwater Stormwater comments are attached along with copies of redlined plans and drainage and erosion control report. Engineering Engineering comments are attached along with copies of redlined plans WaterMastewater a. Coordinate landscape design with civil design. Include standard general notes pertaining to separation distances and locates on all sheets of the landscape plan. b. Cathodic Protection test stations are to be moved by City crews. Correct all notes pertaining to CO stations to read "Contact City of Fort Collins Utilities at 221-6681, 48 hours prior to relocation of CP test stations to coordinate relocation." C. Show and label all valves, access manholes and other items associated with Harmony Transmission main in all vies. Vault lids are not permitted in sidewalks. d. Pothole Harmony Transmission main and electrical ducts along Harmony now in order to finalize design. _ e. Move meter pit for proposed building out of sidewalk. f. Label all fittings, plugs, thrust blocks etc. on services and fire lines. g. Provide sizes for all sanitary sewer services and include their inverts when installed into manholes in profile view. further than 20 feet away from any public street, sidewalk or pedestrian way and requires that the "visual and acoustic impacts .....are fully contained and out of view ...." e. The image analysis submitted as part of the building height review is of inadequate quality. It is difficult to discern the foothills in the background in order to identify the extent of the blockage of any views from Harmony Road. Please submit a better quality rendition. f. In scaling the width of the sidewalk adjacent to the private road, it appears to be 4 to 5 feet. Sidewalks are to be 6 feet in width. g. Directional handicap ramps need to be used for the sidewalks at all intersections. h. Stop signs should be provided on both the northern and southern legs of the intersection of Timberwood Drive (and the private'road on the north) and the entry from Timberline Road. i. Please provide a further description of what an "enhanced" crosswalk will be. A detail of these walkways must be provided. The right-of-way for the unused entry off of Timberline Road will need to be vacated. Please coordinate this with Tim Blandford of the Engineering Department. k. The site plan needs to indicate an enhanced pedestrian crossing of the Timberwood entry from Timberline Road as well as the extension of the sidewalk to join the existing sidewalk at Timber Creek PUD. I. Please show a sidewalk on the eastern side of Snow Mesa Street on both the site and landscape plans. M. Street trees must be provided on both sides of the Snow Mesa Street entrance from Harmony Road. Please show these on the landscape plan. n. Please consider extending the berm adjacent to the service area to the north with additional trees. This would enhance the buffering of the mechanical equipment located there. o. Thank you for a much better submittal of architectural elevations. One remaining comment concerns the screening of the rooftop mechanical equipment.

Metal halide lighting is acceptable for highlighting the hospital logo. However, the light needs to be highly directional to prevent any spillage outside of the logo boundaries. b. The photometric plan is unreadable at the upper portion near Harmony Road. Please resubmit a readable copy. This plan must show the effects of the on -site lighting off -site for a minimum distance of 20 feet. Section 3.2.4(D)(8) of the Land Use Code requires that light levels measured 20 feet from the property line be limited to one -tenth (0.1) foot candle as a result of the on -site lighting. C. The Electric Site Plan indicates flag poles are planned near the water feature at the entrance to the MOB. These are not shown on any other plan sheets. Please ensure the various plan sheets are consistent. d. Your response letter indicated that a trash compactor is to be located in the service area. This is not shown on any of the plan sheets.
