Specifically, section 7.3.1-A makes reference to the City of Fort Collins street sections figures 7-1F through 7-13F. A variance is requested to allow for deviations from the City of Fort Collins street cross-sections to accommodate specific site conditions and the modified block patterns envisioned for the Montava project. Proposed Alternate Design: The proposed street cross sections vary from the LCUASS City of Fort Collins street cross sections by a change in one or more of the following street components: minimum right-of-way (ROW) width, roadway width, parkway width, medians or fence setbacks. The specific alternate designs are as follows: 1. Commercial Local with Bike Lanes– Request for modified street section (Street 5A): a. Refer to Attachment 1 for reference. b. Comparison to Standards and Justification: i. Increase roadway width by 2’ from 50’ to 52’ to allow for wider parking lanes. Parking lanes increase in width by 1’ from 7’ to 8’. 2. Commercial Local without Bike Lanes– Request for modified street section (Street 5B): a. Refer to Attachment 2 for reference. b. Comparison to Standards and Justification: i. Increase roadway width by 2’ from 34’ to 36’ to allow for wider parking lanes and safer parking. Parking lanes increase in width by 1’ from 7’ to 8’. ii. Reduce minimum ROW width by 6’ from 72’ to 66’. P a g e 2 | 4 3. Narrow Residential Local – Request for modified street section (Street 6B): a. Refer to Attachment 3 for reference. b. Comparison to Standards and Justification: i. Reduce roadway width by 2’ from 30’ to 28’ by eliminating parking on one side and parking shall be on one side only; ii. Allow a narrow residential local in less urban areas and provide wider parkway and sidewalks. 4. Connector Local with Attached Green – Request for modified street section (Street 7B) a. Refer to Attachment 4 for reference. b. Comparison to Standards and Justification: i. Increase roadway width by 12’ from 36’ to 48’; ii. Remove sidewalk from ROW on one side and provide sidewalk easement on private property. 5. A. Local Paired One-way, T4 & T3 – Request new street section (Street 8) a. Refer to Attachment 5 for reference. b. Comparison to Standards and Justification: i. Provide ROW width of 50’ for each side of one-way streets; ii. Provide roadway width of 20’ for each side of one-way streets, iii. Provide private center median. 5. B. Local Paired One-way, T5 – Request new street section (Street 8) a. Refer to Attachment 5 for reference. b. Comparison to Standards and Justification: i. Provide ROW width of 53’ for each side of one-way streets; ii. Provide roadway width of 20’ for each side of one-way streets, iii. Provide private center median. 6. Variance request for fencing setbacks from the street right-of-way a. We request reduction of minimum fencing setbacks along all Commercial Local, Residential Local, Connector Local, and Paired One-Way Local Streets street rights-of- way and as indicated in Chapter 16.2.1. L. and Figure 16-1 of the Larimer County Urban Area Street Standards in Transects T4 and T5 of the Montava PUD Master Plan in the following conditions: i. Fences must be set back a minimum of 4 inches from public sidewalk in all instances. ii. Fences/walls 3 feet in height and below are not subject to additional setbacks. iii. Fences/walls over 3 feet in height must be set back from the inside edge of sidewalks the minimum sidewalk width specified in LCUASS for the street type plus 2 feet. For example, a local street requires a 4.5 foot sidewalk plus 2 feet for fencing setback which equals 6.5 feet from the inside edge of the sidewalk. Lots on local streets with 6 foot wide sidewalks must have fences set back a minimum P a g e 3 | 4 of 6 inches from the outside edge of the sidewalk, which equates to 6.5 feet from the inside edge of the sidewalk. iv. Where the desired appearance is fencing with zero setback from sidewalks, a sidewalk extension may be provided on the private lot. A control joint must be provided to separate the public and private sidewalks. Example photos: Exhibits of the City of Fort Collins street section alongside the proposed street cross-section are attached to this letter in support of this variance request. Justification Montava’s design implements key aspects of the subarea plan and the City’s mixed-use goals. In order to accomplish these, the development will take the form of seamless neighborhoods and centers, supported by calm, walkable streets unfrosted by active and human-centric buildings. This requires a greater diversity of P a g e 4 | 4 streets and a reduction of barriers and buffers between uses and neighborhoods. Compatibility between uses and intensity of development is handled by gradually increasing and decreasing development intensity by controlling the form and scale of buildings as well as the diversity of activities that take place within them. Street design is intended to stitch these uses together, not separate them. The variances sought provide a wider range of local street conditions and coordinate the design of collectors and arterials with adjacent site and buildings. These are necessary to achieve a connected and integrated series of neighborhoods that support commercial centers, encouraging residents to walk and bike as a primary means of transportation. Generally, the dimensional changes proposed provide more sidewalk and parkway space than standard sections. A few, limited cases, augment or reduce bicycle accommodations in order to promote a roadway character that reduces vehicle speeds and provides a pleasant pedestrian environment. These do not reduce overall bicycle connectivity in any way, however, as the full network of streets and trails provide numerous and frequent bicycle accommodations in every direction, on street and in trails. Additional local street types are added to support key open space, stormwater, and trail features throughout the project. Additionally, new residential locals are provided to account for staff’s concerns with a number of recent developments in the City where the current residential local yield street standard has been built along with alley-loaded housing. In these case’s there are insufficient breaks in parked cars which causes the yield configuration to fail. The proposed residential locals provide the narrowness of roadway desired to control speeds and character while ensuring vehicular movement is unencumbered. Generally, the requested variances are reasonable and related directly to the desired development character communicated in the subarea plan and supported by common mixed-use development practices across the country. There is no foreseen adverse impact to capital and maintenance costs relating to this variance request. This variance is not foreseen to be detrimental to the public health, safety, and welfare nor reduce the design life of the improvement.
