ECONOMIC DEVELOPMENT  
3. Economic Development supports CAVCO coming to El Mirage and 
Copper Wing Logistics Center.  This development will become the largest 
building and the largest employer in the City.  CAVCO has a great 
reputation as a company and compliments the existing non-retail 
businesses.  The 40 acre parcel will see a significant increase in property 
taxes from current Class 6 to Class 1.  Job creation is projected to reach 
500 jobs.  Indirect jobs will also increase with an average three to one 
ratio.  The development will improve retail attractiveness by increasing 
lunch crowd size.    
 
FIRE DEPARTMENT

FROM: 
Bryce Christo, P.E., Assistant City Engineer 
SUBJECT: 
Cavco West Development Application Review  
DATE: 
02-10-20 
 
Below are the Engineering Division’s comments for the above referenced submittal prepared in 
January 2020. These items will have to be addressed prior to the Planning and Zoning 
Meeting. 
 
Site Plan 
1. If the basins are deeper than 3 feet, the side slopes shall be flatter. The north basin is 5.5 
feet deep and therefore shall have maximum side slopes of 6:1. The rear basin is 3.5 feet 
deep and shall have maximum side slopes of 4:1. 
2. The project is responsible for the drainage generated by the half right of way of Ramirez 
Road along its frontage. A structure will be required at the east end of Ramirez Road to 
capture these flows and retain them on site. 
 
Landscaping Plans 
3. Trees shall not be placed within the 8’ PUE. Trees shall not be placed within 5 feet of a 
public sidewalk or curb. 
4. Hydrants shall have 3 foot minimum clearance per City Detail EM-361.

requirements. 
b. Note 16 – There are two Note 16s. 
c. The storm drain pipes are called out but not shown. 
2. Project Code Data 
a. Parking spaces for the office shall be calculated as ((25,000 x 0.90) / 1,000) x 3 =

b. The plans group the manufacturing use with the warehouse use but the City has 
separate parking space requirements for these uses. Manufacturing requires 1 
space for every 450 square feet of floor area and one space for each company 
truck not stored within the building. Warehousing requires 1 space per 1,000 
square feet of floor area, 1 space per employee on the maximum shift and one 
space for each company truck not stored within the building. The floor area, in

both cases, shall be determined on the basis of the exterior-area dimensions of the 
building, structure, or use multiplied by the number of floors, minus 10%. Please 
revise the required parking spaces. 
c. Verify the total number of parking spaces provided and update the table 
accordingly. 
d. The number of ADA spaces required is based on the total spaces provided. For a 
total of 468 spaces, 7 standard ADA spaces and 2 van accessible ADA spaces are
