SUMMARY: The applicant has requested a Stream Margin Review Exemption to make drainage improvements on the west and south side. of the home underneath an existing flagstone walkway and patio. The home lies within the Stream Margin Review area. Due to the environmental significance of Aspen's watersheds, development projects located within the 100-year flood plain and/or 100 feet of the Roaring Fork River's high-water line (i.e. Stream Margin Review Area) are subject to heightened review under Title 26.435.040 of the City of Aspen's Land Use Code. STAFF EVALUATION: Pursuant to Section 26.435.040[B], The Community Development Director may exempt certain types of development within the stream margin review area if the development meets the criteria for an exemption. The existing home on the property was granted Stream Margin review approval in 1991. The property is heavily treed and relates very closely to the Roaring Fork River and the 100-year floodplain. The approved Top of Slope (established after the 1991 approval) for this area is a significant distance to the west on the next property away from the river. The proposed drainage system involves excavating portions of an existing flagstone patio and walkway, installation of new aggregate material and drain pipe along the west and south facades of the house; and an infiltration bed for the drain system on the southeast corner of the existing flagstone patio. Page t of Due to the limited nature of the proposed changes as they relate to existing development Planning Staff finds that the proposed development meets the exemption criteria as stated in 26.435.04.0.8. For further detail on the review criteria and staff findings, please refer to Exhibit B. The Parks and Engineering Department additionally reviewed the application. Due to site conditions (relationship to 100 year floodplain and established trees) following conditions of approval are required: 1. The patio area shall not be increased to accommodate the infiltration bed, it must be installed within the existing footprint. 2. The location of the infiltration bed shall not extend into the 100-year flood plain. For building permit submission, please also indicate if the infiltration vault will be constructed on -site, or pre -fabricated and installed. 3. For building permit submission, describe or show how runoff is routed to the proposed pipe. Include any inlets in the flagstone patio/walkway or roof drains. 4. Dripline excavation permit is required. New pipeline will be required to be as close to existing foundation as possible to reduce impact to tree root zones. No roots over 2 inches can be cut without written approval of City Forester. 5. Excavation shall utilize hand tools only. DECISION: The Community Development Director finds the request for Stream Margin Exemption at 1035 E. Hopkins Ave. as noted above is consistent with the review criteria (Exhibit B) and thereby, APPROVES the Stream Margin Exemption, subject to the five conditions identified above.
