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.

shall have maximum side slopes of 4:1.

Noted, civil plans will be updated.

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.

Noted, civil plans will be updated.

Keynotes
a. Note 15 -If a dry well is removed, it will need to be abandoned perADEQ

requirements.
b. Note 16 - There are two Note 16s.
c. The storm drainpipes are called out but not shown.

Note, Keynote 16 is located in the retention. | adjust the line work to help see it. Item A and C will
be updated on the civil plans.

a. Parking spaces for the office shall be calculated as ((25,000 x 0.90) / 1,000) x 3 = 68
spaces

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.

b. Verify the total number of parking spaces provided and update the table
accordingly.

c. 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 required for a total of 9.

d. The “Occupancy” Section shows the Warehouse/Manufacturing as 454k square feet
while the “Parking Calculations” Section show it as 480k square feet. Which
is correct?

Parking calculation have been update.

This plan states that the existing chain link fence along the west property line will remain. Is this a
chain link fence? The Civil Plans call for a new chain link fence. Which is correct?

Based on site survey the fence was installed by the neighbor to the west. Cavco would like to keep
it. Existing neighbor is a similar open yard work area/ uses.

Trees shall not be placed within the 8’ PUE. Trees shall not be placed within 5 feet of a public
