Zoning Department Comments: Sophie Varga, sophie.varga@aspen.gov Please refer to the Residential Zoning Checklist and Model Zoning Submission for the information that needs to be provided on every sheet. An example would be the elevations – elevations need to show existing and proposed grade and the maximum allowed height offset from the most restrictive grade. 1. Please provide a zoning summary sheet. 2. Please provide sections. 3. Floor Area: a. We encourage the applicant to provide more than 2 SF of unbuilt floor area. b. Please show existing and proposed grade on the subgrade wall calculations. c. Please reach out to work through deck area calculations. d. Provide sections for the attic. e. Please provide proposed floor area summaries unit by unit. 4. Setbacks: a. Show the separation between the dwelling units as a setback on all applicable sheets. b. Please update L.1.00 and A-0.0 to accurately reflect the setbacks. c. Dimension all projections into the setback. d. Please provide details to show that the pool and deck to the east of the pool comply with the setback regulations. e. A variance needs to be requested for the stairs from the screen porch. f. Provide details for planters and built-in grill. 5. Height: a. Without a height over topography sheet, proposed height measurements cannot be reviewed. b. The chimney on the addition is on a roof with a pitch of 12:12 and goes above the ridgeline of the structure. Please lower the height of the chimney or show that the height of the chimney is necessary to meet building code. Please note that currently the chimneys on the historic resource meet this code; the top of the reconstructed chimneys is below the ridgeline of the addition. If the ridgeline of the addition is lowered, the height of the chimneys will need to be examined. 6. Demolition: Provide demolition calculations. It appears that demolition is going to be triggered. All non-conformities that are proposed to be maintained need to be reviewed. 7. Site Coverage: provide an existing and proposed site coverage diagram. The coverage should be measured as the gross area of the building where it meets the ground; there are no exemptions for staircases and the like. 8. Where will mechanical equipment be placed? 9. Parking: please dimension the required third parking space. Engineering Department Comments: PJ Murray, pj.murray@aspen.gov Land Use Comments: To be addressed through the land use approval process 1. Sidewalk is not required at this property per the Sidewalk Deferred Zones defined in the Engineering Standards, however Engineering supports the installation of a sidewalk in the ROW as proposed in this land use application. 2. ADA compliant ramps need to be installed at the corner of Bleeker and 2nd St with the proposed sidewalk. Confirm layout and grading is achievable. Final grading can be determined at building permit. 3. What is the proposed stormwater treatments approach? The drainage design needs to be clearly communicated on these plans. Confirm detention is not required for this property. 4. What transformer serves the property and does the existing transformer have capacity for the increased use? Will this property require a new transformer? Work with the City Electric Department to determine available capacity. A Load Calc Form will be required at time of building permit. 5. Is the transformer in the SE corner a proposed transformer? Does this property connect to this transformer? Are adequate easements provided for this transformer? What size is this transformer? 6. It appears that parking is proposed within the easement, this is not permitted in the easement so access to the transformer is maintained at all times. If this is a new transformer it needs to be replaced fully within the property boundary rather than bridging the property line. 7. A telephone pedestal is shown in the transformer easement, this is not permitted in easement. Please revise. 8. Access is only permitted off the alley per the Engineering Standards. Remove the access to the historic garage as shown on L.1.00. Building Permit Comments: To be addressed at time of building permit submittal 1. Complete the call outs that note the curb type and detail number shown on sheet C1. 2. Applicant will be required to follow the requirements of a major development within the URMP. Please follow the requirements outlined in Appendix A. 3. Provide excavation stabilization plans that meet the requirements outlined in the Engineering Standards. 4. Confirm water service line size and material, address how the water service line will reach the proposed location of the mechanical room, verify if the structure will require a fire suppression system, show abandonment of existing line, etc. If a 2" service line is required for fire suppression, a memo from a fire suppression company stating a smaller line size will not provide adequate flows is required.
