Mill Street, Suite 101 Aspen, Colorado 81611 PJ.Murray@Aspen.gov Subject: 233 West Bleeker Street HPC Review Comment Responses PJ: Thank you for your thorough review of our project. Please find your comments and the associated responses listed below for the above-referenced project. The following are 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. YCCD Response: Thank you for the clarification. We will remove the public sidewalk from the project. 2. ADA-compliant ramps need to be installed at the corner of Bleeker and 2nd Streets with the proposed sidewalk. Confirm layout and grading is achievable. Final grading can be determined at building permit. YCCD Response: Per comment #1, the sidewalk can be omitted from the project. Therefore, this comment is no longer applicable. 3. What is the proposed stormwater treatment approach? The drainage design needs to be clearly communicated on these plans. Confirm detention is not required for this property. YCCD Response: Given the tight site constraints, we propose to utilize a below-grade detention and infiltration system such as StormTech in the front yard. This will be sized for the WQCV. Being in the Aspen Mountain drainage basin, no detention for the major storm event is necessary. The updated drawings now show the proposed storm infrastructure. We will collect all of the runoff from impervious areas on-site and convey them to the below- grade chambers beneath the front yard. 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 calculation form will be required at time of building permit. YCCD Response: Our design team has been coordinating with Ron Christian at the Electric Department. He confirmed the existing transformer south of the alley (adjacent to two Second Street) has capacity to serve the projects at both 233 and 219 West Bleeker Street with 400 amps of power each. It is the intent of the architect and electrical engineer to P.O.

We understand a load calculation form will be required with the building permit submission. 5. Is the transformer in the southeast corner a proposed transformer? Does this property connect to this transformer? Are adequate easements provided for this transformer? What size is this transformer? 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 placed fully within the property boundary rather than bridging the property line. YCCD Response: Yes, this was a proposed transformer – intended to be shared with adjacent 219 West Bleeker Street which is slated for construction concurrent with 233. But since corresponding with Ron Christian, we no longer believe this new transformer is necessary. Please see #4 above. The easement is now only necessary for the relocated communication pedestals. 6. A telephone pedestal is shown in the transformer easement. This is not permitted in easement. Please revise. YCCD Response: Per items #4 and #5 above, the proposed transformer is no longer necessary. The easement is now just for the relocated communication pedestals. 7. Access is only permitted off the alley per the Engineering Standards. Remove the access to the historic garage as shown on L.1.00. YCCD Response: We have requested this be removed from the landscape plans. The following comments are to be addressed as part of the building permit submission process: 1. Complete the call-outs that note the curb type and detail number shown on Sheet C1. YCCD Response: Since submitting these drawings, we have coordinated with the Engineering Department to confirm the existing curb & gutter may remain as it is relatively new and in good shape. We will call out the curb type where required to be removed and replaced for the water service construction. 2. Applicant will be required to follow the requirements of a major development within the URMP. Please follow the requirements outlined in Appendix A. YCCD Response: We understand and concur. 3. Provide excavation stabilization plans that meet the requirements outlined in the Engineering Standards. YCCD Response: We understand and concur. 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-inch service line is P.O.

YCCD Response: We understand and concur. Sincerely, Justin J. Yarnell, PE Colorado PE Number 47241
