Facility Requirements

Facility requirements are derived from:

• Aviation Demand Forecasts – estimating future demand levels

• Design Standards Review – analysis of compliance with standards

• Facility Maintenance – ongoing care for existing facilities

• Support Facilities – other related infrastructure such as security fencing, equipment, etc.

Each of these categories will impact the need for:

• Airside facilities – runways, taxiways, navigational aids, lighting

• Landside facilities – hangars, aircraft apron, automobile parking

Public Engagement• Planning Advisory Committee• Other public engagement activities

Sources of Facility Requirements

Summary of Facility Comments

Community Connection• Create public observation areas• Increase other public uses of airport property such as educational facilities, restaurants, and shops• Improve pedestrian, bicycle and public transit access to and around airport property• Integrate terminal area with Washington County Fairplex• Find ways to increase community compatibility• Add facilities like dog parks or community gardens on airport property

Economic Development• Preserve the possibility of future commercial service or air cargo• Increase economic opportunities on airport property• Add parking for employees and travelers

Development Strategies• Preserve natural resource areas and reduce impervious surface area• Consider alternative locations for a new terminal building• Close or relocate Hillsboro Airport

Facility Requirements Summary

11

AIRSIDE CONSIDERATIONS

Airside Facility Element Requirement

Airfield Capacity - No issues through long term

Runway Length - Consider up to 7,500 feet of total runway length for main runway

Runway Design Standards - Corrections to runway safety area (RSA), object free area (ROFA), runway protection zones (RPZ), obstacle free zone (OFZ)

Taxiway Standards - Review geometry for compliance to standards

Instrument Approaches - Consider lower visibility minimums

Facility Requirements Summary

12

Landside Facility Element Requirement

New Hangar Needs - 98,800 sq.ft. of additional hangar space, associated parking, and access roads

New Apron - 13,000 sq.yds. of additional apron, or as needed to support new development

On-Airport Land Use - Meet aviation needs first, reserve flight lines for aviation uses only; remainder can be used for other development to support financial sustainability

Terminal Facility Element Requirement

Terminal Area (Subarea) - Consider redevelopment opportunities

Terminal Building - Consider replacement and potential relocation

Terminal Parking - Up to 265 new spaces for a total of approximately 700 parking stalls

Alternatives Criteria Discussion

Community planning compatibility: Conformance with community plans, flexibility to adapt with

changing circumstances, preserving opportunities, proposing socially feasible development, meeting needs of multiple stakeholders.

Environmental factors: Increasing the compatibility with neighboring uses with typical airport

operations. Includes natural resources, air quality, storm water, noise, airport-induced traffic, etc.

Financial factors: Considers the financial sustainability of the airport, balancing costs with expected

benefits, opportunities for new/increased revenues and business success on and around the airport.

Operational safety and efficiency: Increasing the overall operational safety and efficiency of the

airport as it grows to meet future traffic levels. Includes meeting all applicable FAA regulations.

Seismic resilience: Enhancement of facilities to be better capable of recovery following a major

earthquake. “Resilience” means investments made prior to a major earthquake allow for a quicker recovery.

Social equity: Aimed at the equitable distribution of community and economic benefits while seeking a

proportional distribution of any airport impacts.

Alternatives Considerations

Facilities Common to All Concepts• Meeting FAA Design Standards• Maintain existing instrument approaches/NAVAIDS• Maintain existing runways (length and width)• Helipad location (already evaluated in prior studies)• Fire Station (fixed)• Certain structures/historical building location (long term lease/historical)• Preserve recent public/private facility investments

Alternative Facilities Examined • Cornell parcel – Future uses to be accommodated• Alternative terminal locations• Alternative flight school(s) locations• Locations for hangars

- Large/FBO- Corporate Flight Depts.- Individual Box Hangars- T-Hangars

• Alternative based tie-down locations• Airport support facilities

- Maintenance/storage buildings- Centralized fuel farm(s)- Vehicle service road alignment

• Non aeronautical compatible development• Reserve land for future aviation• Reserve for environmental/storm water management

16

Airfield Focus Areas• Hot spots

• RIM location

• ROFA penetrations

• Direct access

• Wide expanse of pavement

• RPZ existing incompatible land uses (roads)

RIM: Runway Incursion MitigationROFA: Runway Object Free AreaRPZ: Runway Protection Zone

17

Runway 31L RPZ

• RPZ = Runway Protection Zone

• Consider lower visibility minimums

• RPZ size based on visibility minimums and the type of aircraft

• Lower visibility minimums equates to a larger RPZ (greater safety margin)

• Standard is for compatible land uses

• Existing incompatible land use is Cornell Road

• Lower visibility would require FAA HQ approval due to new incompatible RPZ land uses

18

Roadway Improvements Considered

• Impact of planned / considered area roadway improvements

• City of Hillsboro considering improvements to Cornell Road -Opportunity to shift Cornell Road out of ROFA?

• Sub-area detail study

• Will add additional incompatible land use to Runway 31L RPZ, requiring FAA HQ approval

ROFA: Runway Object Free Area

RPZ: Runway Protection Zone

19

Runway Extension Evaluation

• 900-foot extension shown

• Evergreen – RSA penetration

• Option 1: Reroute Evergreen around RPZ

• Option 2: Tunnel Evergreen

• 25th Ave is rerouted outside ROFA

• Coordination with Jackson East Planning

RSA: Runway Safety Area

RPZ: Runway Protection

Airside Considerations - Summary

Facility Requirement Recommendation

Runway length -Maintain current runway dimensions

Runway object free area -Pursue FAA Modification to Standard in the short term. Improve when feasible in the long term.

RPZ land use compatibility and instrument approachimprovements

-Do not introduce new RPZ incompatible land uses and mitigate existing RPZ incompatible land uses where feasible

- Acquire RPZ land not currently owned- Maintain existing instrument approaches and existing RPZ dimensions

Direct access from aprons to runways

- Alter taxiway geometry where practicable

Hot spots - Alter taxiway geometry where practicable

Runway Incursion Mitigation (RIM) location (Twy A8)

- Alter taxiway/hold apron interface to mitigate RIM location

Wide expanses of pavement - Alter taxiway geometry where feasible

Cross runway connectivity - Construct when FAA funds become available

• AEDT Noise/Emissions model

• Day-Night average sound Level (DNL)

• 65 DNL is threshold of significance

• 55 DNL is for Oregon informational purpose

• Helicopter impact is noticeable

Day-Night Level: A model of the average noise level; nighttime noise is weighted higher

AEDT: Airport Environment Design Tool; noise / air quality modeling tool

Noise Contours 2016

• All concepts move general aviation and helicopters to north

• Helicopters moved to planned helipad on northside

• Additional fixed wing GA on north side

• No homes in 65 DNL

Noise Contours 2036

24

North side:• Reserve for small GA (as previously planned)• Encourage a mix of small GA and corporate• Relocate terminal building here• Identify non-aviation development lands• Potential control tower location

East side:• Redevelop T-hangars for corporate hangars• Corporate hangars north of Taxiway F• In-fill T-hangar area with T-hangars• Relocate terminal building here

South side: • Terminal here or relocate• Flight school here or relocate• Other aviation hangars or relocate them

West side:• In-fill undeveloped areas only• Relocate T-hangars and re-develop with FBO type hangars• Maintain control tower location
