Review and Action on a Class B Conditional Use Permit for the Microsoft CYS07 Parking Area and Laydown Yard.

Summary

This item seeks a Class B Conditional Use Permit for the Microsoft CYS07 Parking Area and Laydown Yard, an 11.09-acre project located in Laramie County, Wyoming, south of Happy Jack Road. Developed by AVI, PC on behalf of Hensel Phelps, the project will serve the adjacent Microsoft CYS07 building site.

Key Project Components:

• Parking: Provides 614 spaces (12 ADA) on 7.20 acres of paved surface.
• Staging Area: Includes a 3.88-acre gravel laydown yard, 46 job trailers, 4 bathroom trailers, 8 break trailers, a nurse trailer, a security shack, and a connex structure.
• Access & Roads: Features a new 30-foot paved access road connecting to Happy Jack Road and a 40-foot gravel haul road.
• Utilities: Connects to an existing 12-inch city water main and includes a proposed septic tank/leach field. A 6-inch fire line is also planned.
• Drainage: A 70,662 cubic foot detention pond and concrete channels are designed to manage stormwater runoff.

Agency Concerns & Conditions:

• Wyoming Game and Fish identified the site as crucial pronghorn winter range and recommends avoiding construction activities between November 15th and April 30th. This is a mandatory condition for approval.
• WYDOT requires a detailed traffic impact study and access permits, noting the proposed access location does not meet minimum spacing criteria. The project is expected to generate 2,400 daily vehicle trips from an estimated 600 employees.
• WAPA requires a permit for crossing transmission line easements.
• All agency comments must be addressed on the site plan before a Certificate of Review is issued.

Citizen Impact

This project will significantly increase traffic on Happy Jack Road due to an estimated 2,400 daily vehicle trips from construction workers. Residents may also see increased noise and activity in the area, and there are environmental concerns for pronghorn winter range during specific months.
