None was provided in the detail sheets 27 Issue Contact: Basil Hamdan Please address where the flows at the end from Fromme Prairie Way get to the natural area. A blow out with the actual detail to be used should be provided, since the plans reference sheet 15 where two different types of details are shown. Department: Transportation Planning 28 Issue Contact: Kathleen Reavis has street lighting issue been resolved on Fromme Praire Way? Be sure and return all of your redlined plans when you re -submit. If you have any questions regarding these issues or any other issues related to this project, please feel free to call me at (970) 221-6750. Yo s Truly, S EVE OLT City Planner Page 5 Department: Stormwater Utility 17 Issue Contact: Basil Hamdan Please call out all storm drainage facilities on the overall utility plan sheet. 18 Issue Contact: Basil Hamdan Please provide a low flow pipe conveyance under the sidewalk at the end of Nico way.. The 100 year flows can be passed over the sidewalk as an overflow. 19 Issue Contact: Basil Hamdan Please provide an 18" clearance between the proposed 36" storm sewer in line ST1 and the water line paralleling Nico Way. 20 Issue Contact: Basil Hamdan Please provide ditch company signature on the plans. The storm line crossing of the ditch is at a shallow angle, please revise the crossing, if possible, to be closer to a 90 degree angle. 21 Issue Contact: Basil Hamdan For maintenance purposes the 8 foot sidewalk chase and swale proposed on the south end of Nico Way are not advised. Please consider using a 4 foot Type R inlet with a 15" pipe to pass the.2 year flows, while the 100 year flows can overtop the sidewalk into an overflow swale. 22 Issue Contact: Basil Hamdan Grading is shown in wetland areas at several locations, mitigation might be required. 23 Issue Contact: Basil Hamdan Please add notes to the plan detailing what will happen if ersosion happens downstream of the site. 24 Issue Contact: Basil Hamdan The water quality outlet details provided do not call out the actual elevations for water quality ponds A and B. Please add invert elevation , water surface elevation , and other construction level information to these details. 25 Issue Contact: Basil Hamdan The plans show that the outlet pipe from Water Quality Pond B is discharging outside of the existing downstream easement, please correct. The problem may be with the labeling of the easements on the plans. Page 4 14 Issue Contact: Marc Virata PFA indicates that the detail of the emergency access on the utility plan set should also note that the barricade should be mounted on a flexible joint. 29 Issue Contact: Marc Virata The Plat needs to state that the Fort Collins -Loveland Water District Existing 20' Utility Easement within the plat boundaries is to be vacated with this plat. This area cannot be both "Tract 2" (an Open Space, Drainage and Utility Easement) and a District Utility Easement. If the District does not agree to this, then the Tract 2 designation cannot occur. 30 Issue Contact: Marc Virata The Developer needs to coordinate the placement of street lights along Fromme Prairie Way with Light and Power. 34 Issue Contact: Marc Virata Parks (Craig Foreman) is OK with the design of the drainage at the end of Fromme Prairie Way. Parks will need to sign off on the utility plan set. Department: Light & Power 31 Issue Contact: Monica Moore The proposed water line immediately north of lots 4-8 will preclude the ability of Light and Power to provide electric service to lots 5, 6 & 7 KN Issue Contact: Monica Moore Give the tight site conditions, a utility coordination meeting to determine utility locations, service locations and meter locations will be expected. 33 Issue Contact: Monica Moore Street Trees will need to maintain minimum clearances to streetlights. Department: PFA 1 Issue Contact: Michael Chavez Emergency Access Easement - The "Private Drive" between the cul-de-sac of Nico Way and the cul-de-sac of Colton Court shall be platted as an "Emergency Access Easement". All emergency access easement criteria shall apply. Page 3 u Issue Contact: Marc Virata On Nico Way, there is an instance on both.flowlines where the grade indicated does not equal the calculated grade. 7 Issue Contact: Marc Virata Please indicate where the transition to remove the crown of the street begins with the elevation at the point in accordance with Standard Drawing D-19. The response from the previous round indicated that the spot elevations indicate the beginning of the transition area. As there are two sets of spot elevations (one typically around 20' from the intersecting street and another typically. 60' from the intersecting street) my assumption is that the transitions are designed to occur on the set of spot elevations further away from the intersecting street, however this should still be labeled. , C Issue Contact: Marc Virata On Prairie Ridge Drive as it approaches Nico Way, the presumed transition point has a cross slope at that point less than 2%. 9 Issue Contact: Marc Virata On Colton Court as it approaches Prairie Ridge Drive, the presumed transition point has a cross slope at that point less than 2%. 10 Issue Contact: Marc Virata As drainage noted as historic might possibly effect the trailhead parking area, the Parks Department will need to sign off on the utility plan set. 11 Issue Contact: Marc Virata Standard Detail 7-29A of the Larimer County Urban Area Street Standards is referenced in the details sheet, my assumption is that this detail is for the private drive between the two cul-de-sacs. Yet, the response sheet indicates that flares are not needed, as the drive is 24' wide. Driveway flares are needed for this private drive and should be constructed with Standard Detail 7-29A. 12 Issue Contact: Marc Virata It appears that landscaping requirements along public streets aren't being met along the two northern cul-de-sacs, perhaps due to the roadways extending into exclusive easements? Or are these required under the LDGS? 13 Issue Contact: Marc Virata The certificate of dedication and maintenance guarantee language on the plat needs some tweaking to the language. A copy of the plat language is attached with the comment sheet, this is also available in electronic format if desired. Page 2 �... STAFF PROJECT REVIEW City of Fort Collins" JIM SELL DESIGN, INC Date: 10/19/01 BRAD SAUCERMAN 153 W. MOUNTAIN AVE FORT COLLINS, CO 80524 Staff has reviewed your submittal for HARMONY RIDGE PUD, PHASE 2, PRELIM & FINAL, #49-95B, and we offer the following comments: ISSUES: Department: Engineering O Issue Contact: Marc Virata As previously commented on, dedicate the area used by PFA as a second point of access to Fromme Prairie Way as an emergency access easement on the plat. This area needs to also be an "emergency access" easement (not just "access") in order to allow PFA or other emergency services to have enforcement abilities over the access point. PFA would prefer that both cul-de-sacs provide an emergency access connection out to Fromme Prairie Way. 3 Issue Contact: Marc Virata The District needs to provide the confirmation letter from the District prior to a public hearing. 4 Issue Contact: Marc Virata The response letter from TST states that the existing Water District easement will be modified within the boundaries of the plat. Modified or vacated? The District Easement needs to be vacated in order to allow Tract 2 to exist as an open space, drainage, and utility easement - dual designation of this area cannot occur. The District's comment letter for this round specifically stated that "Tract 2 is a District Easement, the reference to open space, drainage and utility easement is to be removed". If the District will not allow any use within their existing easement and will not vacate their right to this easement, then the current design has issues. The two cul-de- sac streets will need to be moved south to ensure standard right-of-way and utility easement dedications are not encroaching on the District's easement. The City will not be in favor of any scheduling for a hearing date until this issue is resolved and the District provides a confirmation letter regarding this issue being resolved. 5 Issue Contact: Marc Virata Two retaining walls are being proposed on Sheet 6 of the utility plan. Retaining walls cannot encroach into the utility easement behind the right-of-way of Nico Way. The District also has indicated a concern with the retaining walls in proximity to their utilities.
