TITLE:
Consideration and Approval of Grant Agreement: between the City of Flagstaff and Arizona Department of Transportation for the Airport Drainage Plan Improvements.
STAFF RECOMMENDED ACTION:
Approve the Grant Agreement with the Arizona Department of Transportation (ADOT) in the amount of $350,000 for the Airport Drainage Plan Improvements.
Executive Summary:
The Federal Aviation Administration under Federal Air Regulation Advisory Circular 150/5320-5D gives the following guideline: "Storm drainage design is an integral component in the design of transportation facilities. Drainage design for transportation facilities must strive to maintain compatibility and minimize interference with existing drainage patterns, control flooding of the pavement surface for design flood events, and minimize potential environmental impacts from the facility-related storm water runoff."
A drainage system study was done prior to the lengthening of the runway in 2008. There are currently projects planned on airport, such as new hangar tenant projects, and off airport, such as the extension of JW Powell to Lake Mary Road, that could influence the existing storm water runoff from the airport. This drainage improvement plan will assist in preparing for these as well as any changes that may have occurred since the 2008 runway project.

Has There Been Previous Council Decision on This:
No
Options and Alternatives:
- Accept the Grant Agreement which will provide the needed funding to the city for the drainage plan improvements.
- Not accept the Grant Agreement and the funds will be returned to ADOT and city will be required to provide funding for the project or the project will not be completed.
- Not accept the Grant Agreement and the funds will be returned to ADOT and city will be required to provide funding for the project or the project will not be completed.
Background and History:
The Drainage Plan Improvements project will address drainage issues throughout the airport. The last drainage report was completed in 1992. In the event of high intensity rainfall events standing water attracts wildlife which presents hazards to flight operations and is a high concern to the airport.
Key Considerations:
The routing of JW Powell from Pulliam Drive to Lake Mary Road will run adjacent to the existing Airport storm water runoff area. This project can help identify possible needs for the extension of JW Powell. The extension of JW Powell is important to the future of ground transportation for Flagstaff.
Community Involvement:
This project will identify any needed changes or improvements to control storm water runoff down stream from the Airport.
Expanded Options and Alternatives:
This project will provide information for the Airport and community concerning the safe control of stormwater runoff from the Airport.
