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 ‘ Connector Local Street’ and ‘Residential Local Street’ cross-sections to accommodate specific site conditions and local street layouts 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 and utility easement adjacent to ROW. The specific alternate designs are as follows: 1. Connector Local– Request for modified street section: a. Comparison to Standards and Justification: i. Reduce total Rights of Way width by 3’ from 63’ to 60’ by reducing parkway landscaping to 7’ each side (pavement width, travel lanes, and parallel parking width remain consistent with LCUSS Standards). ii. Narrower ROW section accommodates site plan lotting layout. Parkway landscape and maintenance will be provided for by the Montava Metro District. iii. Reduction of continuous 9’ utility easement adjacent to ROW to include 8’ by 10’ pocket easements where required to facilitate utility design. P a g e 2 | 3 2. Connector Local (Alternate 1)– Request for modified street section: a. Refer to Attachment 1 for reference. b. Comparison to Standards and Justification: i. Reduce total Rights of Way width by 3’ from 63’ to 60’ by eliminating on-street parking on both sides. ii. Travel lanes are increased from 10’ to 11’; total travel lane width of 22’. iii. Parkway landscape shall be increased by 5.5’ each side. iv. Narrower ROW section accommodates site plan lotting layout. Parkway landscape and maintenance will be provided for by the Montava Metro District. v. Reduction of continuous 9’ utility easement adjacent to ROW to include 8’ by 10’ pocket easements where required to facilitate utility design. 3. Connector Local (Alternate 2)– Request for modified street section: a. Refer to Attachment 2 for reference. b. Comparison to Standards and Justification: i. Reduce total Rights of Way width by 3’ from 63’ to 60’ by eliminating on-street parking on one side; parking shall be provided on one side only. ii. Parkway landscape shall vary by side; decreased by 1.5’ on side with on-street parking and increased by 6.5’ on side without on-street parking. iii. Narrower ROW section accommodates site plan lotting layout. Parkway landscape and maintenance will be provided for by the Montava Metro District. iv. Reduction of continuous 9’ utility easement adjacent to ROW to include 8’ by 10’ pocket easements where required to facilitate utility design. 4. Residential Local – Request for modified street section (Alternate 2): a. Refer to Attachment 3 for reference. b. Comparison to Standards and Justification: i. Increase total Rights of Way width by 3’ from 57’ to 60’. ii. Increase pavement travel lane width by 4’ from 16’ to 20’. iii. Elimination of on-street parking on one side. iv. Parkway landscape shall be increased by 2.5’ each side. v. Roadway designation of Chesapeake was downgraded from Connector Local to Residential Local through the Phase G Traffic Impact Study, however, a wider total travel lane of 20’ was required by Poudre Fire Authority. Parkway landscape and maintenance will be provided for by the Montava Metro District. vi. Reduction of continuous 9’ utility easement adjacent to ROW to include 8’ by 10’ pocket easements where required to facilitate utility design. 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. P a g e 3 | 3 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 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 locals 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. Additionally, Montava ownership has taken considerable measures to evaluate and coordinate utility infrastructure and services to support the development. The utility infrastructure has been strategically designed and located in support of the street section variances and in conjunction with the alley loaded development. As part of this overall process, coordination and discussions with various utility providers and the city have occurred which have guided decisions on utility service providers to and within the site. Utility easements adjacent to the local and connector roadway were evaluated and determined that continuous easements along the Rights-of Way were not needed. Utility pocket easements, behind Rights- of-Way have been included as necessary. 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.
