Macias, Senior Planner Development Services Department, Planning & Zoning RE: PZ21-04-14 Avanti Windows and Doors Site Plan Approval DATE: September 21, 2021 Mr. Gilmore, Please see the comments from El Mirage Technical Advisory Committee (TAC) for the Development Application for the project mention above. BUILDING & SAFETY 1. No comment. ECONOMIC DEVELOPMENT 2. Economic Development supports the addition of Avanti Windows and Doors. When complete, Avanti will become a top 5 employer in the City. The company has a strong history of supporting City interests and is a recognized leader in its industry. Avanti outreach to City residents to offer employment opportunities to include transportation services to the factory is amazing. Avanti will add to the mix of non-retail developments at Copperwing making it an employment center for the Northwest Valley. ENGINEERING 3. See attached memorandum. FIRE DEPARTMENT 4. Access road needs to be rated for at least 75,000 pounds to accommodate our fire apparatus. 5. Turning radius for fire apparatus is 25 feet inside, 45 feet outside 6. Fire asks that we leave 8in drop (to the east of the main entrance), this will provide the almost double the fire flow from a 6in line. 7. Knox box for fire department access 8. If there are any electronic gates, fire department will require emitters for access. PLANNING & ZONING 9. Site Plan: Parking Lot screen wall shall; break up the lineal expanse of the walls with a centerline, pilasters, three-wall enclosures, varying heights, the 2 installation of extra plant materials, or varying the landscaped area contours to improve the visual impact of the wall. 10. All areas (Future Expansion Area) not being use for parking or storage shall be dust-proof. 11. Landscaping is not required in the back storage or work area. 12. Plant materials that are not acceptable: Cercidium aculeate, Cercidium x ‘Desert Museum,' Dalbergia sissoo, Acacia salicina, Acacia saligna. The Palo Brea trees needs to be replaced. POLICE DEPARTMENT 1. No comment. PUBLIC WORKS 2. Suggest adding multiple 8” isolation water valves throughout their system so if there’s a leak the entire system won’t have to be shut down 3. Multiple hydrants don’t show hydrant valves 4. Several hydrants show 8” supply pipes (should show 6”) 5. Verify plant, shrubs and trees are on our acceptable list Engineering Development Services Department 10000 N El Mirage Road, El Mirage, AZ 85335 623-972-8116; Fax 623-876-4605; TDD 623-933-3258 www.elmirageaz.gov MEMORANDUM TO: Jose Macias, Planner/GIS FROM: Bryce Christo, P.E., Assistant City Engineer SUBJECT: Avanti Windows & Doors Development Application Review DATE: 09-20-21 Below are the Engineering Division’s comments for the above referenced submittal prepared in August/September 2021.
