2 Design Review Committee Staff Report August 22, 2017 DESIGN REVIEW COMMITTEE / LANDSCAPING REVIEW Prior to any ground disturbing activity, the applicant shall submit a landscaping/architectural design plan to the Planning and Building Division for review and approval by the Design Review Committee (DRC). Said plan shall address, but not be limited to: Landscaping material (if plant material: type, size at time of planting, maturation size at full growth, period of time between planting and full growth), landscaping location, landscaping irrigation system. Because the proposal is to grade the site before applying for a building permit, staff is requesting that DRC also review and comment on the temporary soil stabilization of the water treatment plant site.

3 Stantec Consulting Services Inc Sierra Center Parkway, Reno NV August 17, 2017 File: Attention: Washoe County Design Review Committee Washoe County Community Services Department Planning and Building Dear Sirs, Reference: Mt. Rose Water Treatment Plant The Truckee Meadows Water Authority (TMWA) proposes to construct the Mt. Rose Water Treatment Plant (MRWTP). The MRWTP was identified as a critical piece of infrastructure needed to serve customers in the Mt Rose / Galena Fan Area. Washoe County issued TMWA a Special Use Permit (SUP) for the construction of the treatment plant and a water diversion on Whites Creek. The SUP included a condition that requires TMWA submit a landscaping plan for review and approval by the Design Review Committee. This application is intended to provide the Design Review Committee the opportunity to review the revegetation and landscaping plans for the treatment plant and diversion and satisfy the SUP requirement. The project is being implemented in two phases. The first phase includes the construction of the diversion, an access road, mass grading for the treatment plan. The second phase will include various site improvements and construction of the treatment plant. The second phase is expected to begin within six months of completing the first phase. Areas disturbed during the first phase and not given final stabilization, will be treated with temporary soil stabilization pending final stabilization during the second phase. As you will see, THWA has given special attention and consideration to developing revegetation and landscaping plans that provide attractive screening of the facility to the surrounding areas and that is consistent with the local native species. Further, every effort is taken to minimize the area of disturbance. We thank you for your consideration of the proposed project. Regards, STANTEC CONSULTING SERVICES INC. John Buzzone, P.E.
