INNOVATIVE DESIGN AND CONSTRUCTION OF AIRPORT WASHRACK FACILITY

BACKGROUND AND ELIGIBILITY2

Purpose and advantages of an aircraft washrack Aesthetics – protect investment Reduce corrosion potential Opportunity to closely inspect aircraft Provides additional feature/facility for

airport users

FAA Eligibility Classified at national priority ranking:

OT, OT, WR Low NPR, but is eligible for FAA AIP

funding for non-primary airports with non-primary entitlements

PLANNING ANALYSIS3

Visible and easily identifiable Ease of ingress and egress Limited FAA guidance, rely on local requirements Location, Location, Location

DESIGN CONSIDERATIONS AND ALTERNATIVES

Type of aircraft at the airport: General aviation and/or crop dusting aircraft

Type of system is predicated on local jurisdiction for disposal of excess water

Basic operation of washrack system (prior to Benton washrack)

Additional considerations

CASE STUDY ON BENTON AIRPARK5

Pre-project washrack situation Manual water valve Runoff and storm water quality

compliance concerns

Siting considerations for proposed washrack location Existing location and accessibility limitations – not viable Desirable location adjacent to the restaurant and FBO (also provides fuel service) Adjacent to transient parking ramp Proposed location does not impede existing operations or involve valuable space

Existing SiteProposed Site

City of Redding requirements for operation and water quality

• Requested additional control devices to direct and control flow from stormwater runoff into the storm sewer versus washwater into the sanitary sewer system via a clarifier.

• Resulted in system currently in place.

CASE STUDY ON BENTON AIRPARK, continued

Operation of system in-place Checks in place to ensure proper operation

Valves open and close to direct water Level switch in case of system blockage High water level alarm

Ease of maintenance Vertical flow clarifier with “Liftmate” cover

Free draining yard hydrant to prevent freezing

Rigid utility board with secure equipment installation

Sediment and hydrocarbon inserts for area drains to minimize blockage potential

Area light for illumination

9CASE STUDY ON BENTON AIRPARK, continued

WHAT WE HAVE LEARNED FOR NEXT TIME

Water pressure test after connection to the water source

“or equal” equipment considerations and how this may affect infrastructure installation

Sanitary sewer tie-in and design assumptions

Commercial hose fittings = marine fittings, this will likely be an issue if nozzle is not provided
