HomeMy WebLinkAboutHEARTHFIRE PUD, 2ND FILING - FINAL - 31-95E - CORRESPONDENCE - CITY STAFF (17)PAGE 7 February 24, 2000 Project No: 1552-02-97 Re:) Hearthfire P.U.D., Second Filing; Ft. Collins, Colorado We would request that City Light and Power become involved in the project immediately instead of waiting until construction, which is what occurred with First Filing. With the First Filing, we were required to provide a fairly major revision to the Master Utility Plan after the City Light and Power Department finally provided a plan for electric service which affected all water service locations. This was a costly and time consuming task. It also caused delays in construction. We would at an absolute minimum, request a preliminary design from them so we can incorporate their design into our drawings and coordinate water services now. We understand that there may be a certain fee up front to provide this. We trust that this response has addressed a majority of your specific comments and concerns. If you have any questions or further comments during your next,detailed project review, please call at (970) 226-5334. We would respectfully request a project work session (utility coordination meeting) at your earliest available convenience. Brian W. Shear, P.E. Shear Engineering Corporation BWS/mo cc: Tom Kennedy; Hearthfire, Inc. Steve Olt; City Planning Tom Dugan; PineCrest Planning and Design PAGE 6 February 24, 2000 Project No: 1552-02-97 Re: Hearthfire P.U.D., Second Filing; Ft. Collins, Colorado • North County Road 13 has not been profiled for 500' north of Douglas Road. No design is necessary since the profile exists and the proposed Douglas Road profile will match existing. A profile for 500' beyond the south limits of construction for North County Road 13 will be provided. Additional survey data is required and was unavailable at the time of this response. UTILITY PLAN COMMENTS (Grading Plans) • The grading plans have been updated to represent final grading for North County Road 13. Generally, the proposed North County Road 13 profile is similar to the existing profile. No extensive grading on the west side of North County Road 13 will occur. • Grading has been revised in the southwestern area of the project. We recognize that easements are required for all grading outside the limits of the Hearthfire property. Please note that easements are now represented on the Water Supply and Storage property. Discussions with Water Supply and Storage are occurring. Please note that an easement will also be provided on the Amended Exemption property at the southeast corner of the intersection of North County Road 13 and Douglas Road to supplement the required additional right-of-way. UTILITY PLAN COMMENTS (Details) • The driveover curb, gutter and walk detail provided in the current City street standards clearly identifies driveover curb and gutter. There is not a 12" thickened section. We have referenced the DRAFT Larimer County Growth Management Area Street standards. The driveover curb does not have a 12" thickened back section. We have included a collector intersection detail for detached walk. Detail D-4 for the pedestrian connection at a cul-de-sac has been added. Details D-18 and D-19 have not been added to the plan set. The intersections have been further detailed and now represent transition locations consistent with those noted with the street plan and profiles. All transitions differ. • A bollard and chain has been identified at the intersection of North County Road 13 and the 20' wide crushed limestone pedestrian, bike trail and emergency access road between North County Road 13 and the end of Hearthfire Drive (previously Grosbeak Court). A bollard and chain has also been identified at the south end of North County Road 13 where the emergency access intersects with North County Road 13. These locations are consistent with the revised Site Plan by PineCrest Planning and Design. 0 The dowel detail (detail no. 4) has been added. PAGE 5 February 24, 2000 Project No: 1552-02-97 Re: Hearthfire P.U.D., Second Filing; Ft. Collins, Colorado • The Town Center Drive profile is being tied into the existing Town Center Drive which was constructed with the First Filing. Attached is a copy of the Hearthfire Drive plan and profile for the First Filing for your immediate reference. As previously noted in our response letter dated October 26, 1999, an attempt has been made to accommodate the minimum 0.60% grade requirement for all crosspans. The Town Center Drive crosspan at Buteos Court does not comply. Because it is impossible to meet the 0.60% crosspan grade when a street grade is less than 0.60% (Minimum allowable gutter grade is 0.50%). The crosspan at Town Center Drive and Buteos Court has a grade of 0.56% to match the grade of Town Center Drive (0.56%). The 0.56% grade was carried through the intersection at the flowline from PCR to PCR. This results in a crosspan of varying depths. Please note the proposed Larimer County Urban Area Street Standards allow a varying crosspan depth to accommodate the difference in depths of a curb and the depth of the crosspan. Please note: If the 0.60% minimum crosspan grade standard is to be achieved always, then the allowable minimum street (or gutter) grade must be increased in the standards. With the difference in the depth of the gutter pan (vertical curb and gutter) and the depth of the crosspan, it is impossible to meet a 0.60% crosspan grade when a street profile is less that 0.85%. I would be happy to discuss this issue further. My presentation at one of the Larimer County Street Standards advisory committee meetings regarding this subject, was well accepted and prompted the allowance of varying crosspan depths to accommodate these design discrepancies. • Town Center Way has been revised to meet City Street standards with a 2% grade at the intersection for a minimum of 50' beyond the right-of-way. --Please refer to all revised plans concerning drainage, erosion control, etc. The property line station has been identified and the. end of pavement station has been identified. Please refer to the discussion under the third item of UTILITY PLAN COMMENTS (specific) concerning the Town Center Drive service to the Water Supply and Storage property where Richards Lake is situated. • The profile for Bateleur Court east (previously Buntwing Court) has been revised to identify the low point relative to the inlet location. Please note that the vertical curves on either side of the inlet end with a 0.50% grade into the inlet. • The Bateleur Court west cul-de-sac flowline profile has been revised to indicate a 0.40% grade into the high point. A vertical curve has not been provided. A minimum of 1% cross slope has been achieved in the cul-de-sac. Cul-de-sac details have been updated to reflect the revised cross slopes. • Minimum K-values for Hearthfire Drive (previously Grosbeak Court) noted. This street will not be continued to North County Road 13. This is due to numerous agreement issues and conditions of preliminary approval concerning Hearthfire P.U.D. Please refer to additional response and history by PineCrest Planning and Design LLC. This is attached to this response for immediate reference. PAGE 4 February 24, 2000 Project No: 1552-02-97 Re: Hearthfire P.U.D., Second Filing; Ft. Collins, Colorado • We have provided driveway cuts at the intersection of the Emergency and Whiting Petroleum access with Buntwing Lane (previously Town Center Drive) in order to maintain consistency with what was provided in the First Filing at two (2) other access intersections with public streets. If you feel strongly about the 8' wide handicap access at these points, we ,can easily accommodate. We concur that driveover curb still allows the accessibility required. We invite you to visit the site to see the current access intersections at Hearthfire Drive and Town Center Drive in the locations noted on the First Filing plan which is attached for immediate reference. • A dirt trail has not be provided behind the North County Road 13 sidewalk on the North County Road 13 typical street section to accommodate a riding trail. Please refer to the response from PineCrest Planning and Design (attached) for discussion and history concerning this issue. UTILITY PLAN COMMENTS (intersection details) • All courts have been detailed. • All transitions have now been noted on the intersection details. Please note that all transitions had been noted in the street plan and profiles on both the plan views and in the profiles. The profile clearly identify where actual typical sections begin and end. • The intersection detail for Buntwing Lane (previously Town Center Drive) and Hearthfire Drive (previously Grosbeak Court) has been updated. • The intersection detail for Town Center Drive and Town Center Way has been updated. • The intersection detail for Town Center Drive and Buteos Court has been updated. UTILITY PLAN COMMENTS (Plan and Profiles) • We have checked all vertical curves for appropriate K values. Vertical curves which did not meet current City street standards for K values have been revised. Miscalculated K values have been corrected. Vertical curves with K-values that did not meet City standards have been re -defined. PAGE 3 February 24, 2000 Project No: 1552-02-97 Re: Hearthfire P.U.D., Second Filing; Ft. Collins, Colorado • Hearthfire Drive (previously Grosbeak Court) has not been extended to North County Road 13. This is due to numerous agreement issues and conditions of preliminary approval concerning Hearthfire P.U.D. Please refer to additional response and history by PineCrest Planning and Design LLC. This is attached to this response for immediate reference. • As previously noted in our response letter dated October 26, 1999, Water Supply and Storage, the owner of Richards Lake, required an access to their property (Town Center Way) for futurepotential development. It is a condition of an agreement with Water Supply and Storage. The agreement allows Hearthfire to release stormwater to Richards Lake. We do invite you to discuss this issue with Water Supply and Storage. Please contact Mr. Fred Walker, president of Water Supply and Storage. Water Supply and Storage Company Phone: (970) 482-3433 Attn: Fred Walker; president 2319 East Mulberry P.O. Box 1584 Ft. Collins, Colorado 80522 • The crosswalk at Buntwing Lane (previously the north -south section of Town Center Drive) is a painted crosswalk. As noted with our October 26, 1999 response letter, A midblock cross walk has been provided where the path crosses the street. Drive approaches and pavement markings are shown in all relevant plans. We have clarified this on the plans. • Improvements to North County Road 13 were shown all the way to Douglas Road at the time of your last review. The back of walk was placed at the right-of-way line according to current City Street standards for collectors. This was also represented at the time of your last review. All collector standards were met. Therefore, no changes have occurred. Please re -visit your redlined set which has been re -submitted with this re -submittal. The typical street section for North County Road 13 was also accurate. • The sidewalk connection from the Bateleur Court (west) cul-de-sac to North County Road 13 has been changed to concrete. • A dirt trail has not been provided behind the North County Road 13 sidewalk to accommodate a riding trail. Please refer to the response from PineCrest Planning and Design (attached) for discussion and history concerning this issue. PAGE 2 February 24, 2000 Project No: 1552-02-97 Re: Hearthfire P.U.D., Second Filing; Ft. Collins, Colorado COMMENT SHEET RESPONSE PLAT COMMENTS (General) • Clarification has been made regarding those areas which are to be maintained by Whiting Petroleum Corporation. An area of encroachment by Whiting Petroleum Corporation within the limits of Tract E is the primary area in question. This area has been clearly defined on the plat, and noted by meets and bounds. The easement is labeled as a Whiting Petroleum easement. • A drainage easement has been added to the southwest corner of Lot 26. • The Hearthfire Drive right-of-way which is indicated as being dedicated by separate document has not yet been recorded. It will be dedicated by the Hearthfire Way annexations which are currently being revised. The process is somewhat complicated. The annexation could not be recorded until the Amended Exemption was recorded. The Amended exemption was recorded. The 1/6 contiguity requirement for Annexation was not achieved with the Hearthfire Way Annexation. Therefore two (2) annexations are currently being produced by Frederick Land Surveying. • The main Whiting facilities are located just east of Tract E. There is a certain encroachment of the Whiting facilities on Tract E which has prompted the Whiting Petroleum easement on Tract E. The 25' easements are travelways which ultimately cross Hearthfire Drive to access the Whiting Petroleum facility. Additional easements have been dedicated with the Amended exemption. We have provided a copy of the amended _exemption for your immediate reference. We invite you to visit the site to see the actual relationship of the Whiting Petroleum facility with the 25' access easements. Please note that the accesses are in place and the easements have been dedicated by separate document. The First Filing plan is also attached for your immediate reference. • We have accommodated additional plat comments noted on the redlined plat. UTILITY PLAN COMMENTS (Specific) • As noted with our October 26, 1999 response letter, the North County Road 13 cross sections have been removed from the plan set since they were originally prepared for local street status. There was also an elevation datum discrepancy. The elevations were over 3' off. Please refer to the benchmark description on the Cover Sheet. Our understanding is that cross sections are not required with collector streets according to current City of Fort Collins street standards. February 24, 2000 Project No: 1552-02-97 Sheri Wamhoff City of Fort Collins Engineering Department P.O. Box 580 Ft. Collins, Colorado 80524 Re: Hearthfire P.U.D., Second Filing; Ft. Collins, Colorado Dear Sheri, This is a response to your most recent review comments concerning the Final Utility Plans and Final Plat for Hearthfire P.U.D., Second Filing. This response will address several utility plan and final plat review comments, as well as written comments noted on your Project Comment Sheet signed and dated 11/23/99. This response letter will generally follow the format of your written review comments. Please note that a separate response letter has been provided by PineCrest Planning and Design. We will reference those responses occasionally and have attached a copy of that letter for your immediate reference. There are several comments which have not been accommodated, primarily due to preliminary project approval conditions and conditions of several agreements which were made in the lengthy process to gain preliminary approval of the entire Hearthfire project. Those items noted will be clarified as the comment is addressed. We feel that it may be appropriate to sit down and discuss the history of the project and more formally address certain conditions with a presentation of historical backup documentation. The staff reports for Hearthfire Preliminary would be your best tool for understanding the conditions of approval. We have attached the staff report dated September 23, 1996 for your immediate reference. UTILITY PLAN COMMENTS (General) • Grosbeak Court has been re -named to Hearthfire Drive. • The North -South portion of Town Center Drive has been renamed to Buntwing Lane. • Buntwing Court has been renamed to Bateleur Court at the direction of the Police Department. This results in two (2) Bateleur Courts. We will address these courts with east and west during our response. • We would like to reiterate that project main infrastructure construction will not be phased. The phasing represented on the Landscape Plan is related to Landscaping phasing only and the requirements for an escrow prior to any COs.
