Final Site Plan Review Residence at The COR December 8, 2010 Page 5 of 11 • Maximum private street length without a turnaround provided: 200 feet • Maximum private street length with a turning provision provided: 300 feet • Maximum private street length with a cul -de -sac provided: 600 feet, except that when exceeding 300 feet, the entire length of the private street must be 32 feet wide • Minimum access road width at street frontage: 24 feet • Minimum parking aisle width: 24 feet • Maximum driveway width at road frontage: 20 feet • Edge of curb opening shall not be closer to nearest portion of a street right -of -way intersection that 27 feet or two - thirds of the lot width, whichever is smaller (where a "T" intersection exists, a drive may be located opposite the end of the intercepted street). • Minimum access drive angle to the street: 75 degrees • Building setback from private street, measured from back of curb: 25 feet • Minimum radius at intersection: 20 feet Given the unique nature of this alleyway, the City has flexibility in review and is open to alternative design measures, provided this alley accommodates adequate safety and traffic circulation safety measures. Given that adequate parking is provided in the existing ramp, standards such as driveway length (setbacks from private roads) are less of a concern. Items to consider when evaluating this area include: • Parking restrictions — no parking will be allowed within the area • Signage for private roadway designation and way- finding differentiating traffic circulation for the residents and public utilizing the parking ramp • Maintenance (snow removal, sweeping, etc.) — an agreement will be required for maintenance of the roadway and utilities proposed in this area • Trash collection — single location for all and /or individual pick up for townhomes • Deliveries and /or loading areas for the retail component and residents • Mirrors, flashers, crosswalks, etc. for pedestrian safety Based on recent discussions regarding the alleyway, the current proposal is for no additional connection into the existing parking ramp for additional circulation, and an ingress /egress on Sunwood Drive. This represents a modification to the existing access to the ramp. The main exit for the parking ramp would remain egress to Civic Center Drive only (one -way traffic). The ingress from Sunwood Drive must be clearly marked with signage stating "Caution: Vehicles Backing Into Loading Dock" or similar. As stated above, City Staff encourages additional safety measures to protect the conflict with vehicles backing into the loading dock area and vehicles entering the parking ramp access road. This could include the use of such safety measures as parabolic mirrors. In addition, the alleyway itself shall be clearly marked as `Access to Residence at The COR Only; No Access to Municipal Parking Ramp". Finally, railings shall be added to the north side of the parking ramp consistent with City design criteria on the first level of the ramp for separation between the alleyway and the parking ramp, and to resolve any grade conflicts along that common lot line. Sidewalks. You will be required to construct a sidewalk along Sunwood Drive consistent with existing streetscape along this corridor. During construction, arrangements must be made to preserve and maintain a corridor for pedestrian travel as well. Development Permit: Per City Code Section 117 -54 entitled Site Plans, prior to the City issuing a Building Permit, you must enter into a Development Permit to ensure successful completion of the
