This shall be demonstrated by an engineering study prepared by a professional engineer registered to practice in the State which shows that the base flood elevation will not be raised, including, but not limited to, proposing mitigation techniques on or off-site which compensate for any base flood elevation increase caused by the development. The recommendations of the Aspen Area Community Plan: Parks/Recreation/Open Space/Trails Plan and the Roaring Fork River Greenway Plan are implemented in the proposed plan for development, to the greatest extent practicable. There is no development other than approved native vegetation planting taking place below the top of slope or within fifteen (15) feet of the top of slope or the high waterline, whichever is most restrictive. This is an effort to protect the existing riparian vegetation and bank stability. New plantings (including trees, shrubs, flowers and grasses) outside of the designated building envelope on the river side shall be native riparian vegetation as approved by the City. A landscape plan will be submitted with all development applications. The top of slope and 100-year flood plain elevation of the Roaring Fork River shall be determined by the Stream Margin Map located in the Community Development Department and filed at the City Engineering Department. The proposed development does not pollute or interfere with the natural changes of the river, stream or other tributary, including erosion and/or sedimentation during construction. Increased on-site drainage shall be accommodated within the parcel to prevent entry into the river or onto its banks. Pools or hot tubs cannot be drained outside of the designated building envelope. Staff Recommendation Staff recommends approval of the request for Stream Margin Review and Special Review to establish an Alternative Top-of-Slope and to develop a permanent restroom facility, subject to the conditions listed in Resolution No. 5, Series of 2022
