HomeMy WebLinkAboutTHE GROVE AT FORT COLLINS - PDP - 16-10B - REPORTS - VARIANCE REQUEST (3)Fort Collins intersection, it shall be verified that the intersection meets or exceeds the criteria for turning movements and design vehicles as specified in Section 8.2.8 of LCUASS. d. The variance request to use the parkways and/or bump out areas for rain gardens is a design concept that Engineering is open to exploring. As this idea moves forward we would like to work with you, your designers, and other City departments to determine a design that is acceptable to the City and work through the maintenance requirements, schedule, and parameters that will need to be placed in the Development Agreement outlining the Developer's obligation for maintenance of this area. As identified in your letter, the City Utilities Department has agreed that if any rain gardens in the parkways installed with this project fail despite proper maintenance by the property owner, Stormwater will pay to remove and replace them with normal curb and gutter. Therefore any design will need to accommodate this possibility of the rain gardens being removed. e. Since several variances approved increased the width of the roadway cross section, the tract width (for a Private Street) shall be increased to include the asphalt, curb, gutter, parkway, and sidewalk width. This request identified several proposed cross sections, and as identified above, the different aspects of those sections were either approved, denied, or conditioned. The variance request did not cover and provide for the actual plans showing the design and transitions between sections, transitions from existing street widths, proposed striping, and length of each section. This information will still need to be provided and it is expected that the details of the design will be reviewed and worked out through the development review process. This variance request does not set precedence or change the application of our design standards in other situations. If you have any questions, please contact Sheri Langenberger at 221-6573.

Attachments cc: Helen Migchelbrink, City of Fort Collins Joe Olson, City of Fort Collins Ward Stanford, City of Fort Collins Matthew Wempe, City of Fort Collins Steve Olt, City of Fort Collins file Fort Collins utilized, and how the striping and street curbing transition are installed, shall be further reviewed and approved by the City. f The variance request to utilize bump outs to narrow the street to a 32 ft flowline to flowline width at these points (two 10 ft travel lanes and two 6 ft bike lanes) shall be allowed provided that in any instance that a bump out is proposed at an intersection, it shall be verified that the intersection meets or exceeds the criteria for turning movements and design vehicles as specified in Section 8.2.8 of LCUASS. g.

Variance Request 2 — Variances to Figure 7-6F and Table 7-1 for the design of a Commercial Local street a. The variance request to reduce the standard travel lane width to 10 ft from 11 ft for a Commercial Local cross section is granted. b. The variance to reduce the right-of-way width to accommodate the approved section is approved. Right-of-way shall be provided to accommodate the final street cross section, which shall include the asphalt, curb, gutter, parkway, and sidewalk width. c. The variance request to utilize bump outs to narrow the street to a 32 ft flowline to flowline width at these points (two 10 ft travel lanes and two 6 ft bike lanes) shall be allowed provided that in any instance that a bump out is proposed at an intersection, it shall be verified that the intersection meets or exceeds the criteria for turning movements and design vehicles as specified in Section 8.2.8 of LCUASS. d.

The variance request to increase the standard travel lane width to 18 ft from the standard 16 ft for a Local street is granted. The additional width will enhance mobility for Emergency Services and the public on the curved road. b. The variance request to increase the sidewalk width along the west/north side of the roadway from 4.5 ft to 8 ft is approved. It should be noted that this additional sidewalk width is not eligible for Street Oversizing reimbursement. c. The variance request to utilize bump outs to narrow the street to a 20 ft flowline to flowline width at these points shall be allowed provided that in any instance that a bump out is proposed at an City of F6rt Collins January 28, 2011 Nicolas W. Haws, PE, LEED AP Northern Engineering Services, Inc. 200 South College Ave, Suite 100 Fort Collins, Co 80524 Re: The _Grove at Fort Collins = variance requests Dear Nick, Planning, Development & Transportation Engineering Department 281 North College Avenue P.O. Box 580 Fort Collins. CO 80522.0580 970.221.6605 970.221 M78 - fax fcgov. corn/engineering This letter is in response to the variance request letter sent to me dated January 6, 2011, regarding several variance requests to the Larimer County Urban. Area Street Standards (LCUASS) for the design of streets within The Grove at Fort Collins development. I will address each of the variance requests as I understand them to be. Variance Request 1— Variances to Figure 7-5F and Table 7-1 for the design of Rolland Moore Drive a. The variance request to use a 30 mph (Connector Local) design criteria for the centerline radii, minimum tangent between curves, and a posted speed of 25 mph versus a 40 mph (Collector) design criteria is granted. The design of Rolland Moore Drive from the current west end to Centre Avenue shall be designed in accordance with the requirements of Table 7-3 for a 30 mph design and any additional signage or striping necessary due to the design speed shall be provided by the developer of this project. b. The variance request to reduce the standard travel lane width to 10 ft from 11 ft for a Collector Local with parking cross section is granted for those areas that are travel lanes only and not a combined travel and bike lane. c. The variance request to reduce the parkway width to 6 ft from 8 ft when a grassy strip is provided and to allow for an attached sidewalk with tree wells with a 5 ft versus the standard 8 ft hardscape parkway adjacent to the buildings is denied. It was the position of City Planning that the utilization of an attached wide urban sidewalk was acceptable with the prior proposal, given that the buildings were proposed to be located very close to the street. The current proposed building placement however, does not lend itself to the use of the urban function that a wide urban attached sidewalk with tree wells is intended to provide. With the current proposed building placement, the standard parkway width should be provided with the 5 ft detached walk in accordance with the Collector Local standard. d. The variance to reduce the right-of-way width to accommodate the approved section is approved. Right-of-way shall be provided to accommodate the final street cross sections, which shall include the asphalt, curb, gutter, parkway, and sidewalk width. e. The variance to allow for the utilization of a 16 ft shared bike and travel lane at the intersection of Rolland Moore Drive and Centre Ave, rather than an 11 ft travel lane and 8 ft bike lane per standards, is granted with the condition that the length of the street in which this shared width is
