This Construction Safety and Phasing Plan (CSPP) has been prepared in general accordance with FAA Advisory Circulars (AC) 150/5300-13B, Airport Design; and 150/5370-2G, Operational

Safety on Airports during Construction for the Runway, Apron, and Taxilane Surface Seal

Project at Mulino State Airport in Mulino, Oregon.

I. PURPOSE AND OBJECTIVE

Aviation safety is the primary consideration at airports, especially during construction. The

Construction Safety and Phasing Plan (CSPP) is a tool used to ensure safety compliance when coordinating construction activities with airport operations. This document identifies aspects of the Mulino State Airport Project that pose a potential safety hazard to airport operations and outlines mitigation procedures for each hazard.

The following objectives must be met by the “Team” comprised of the Airport Manager; Oregon

Department of Aviation; the Engineering Design Consultant; the Prime Contractor; and various subconsultants, subcontractors, airport users, and airport tenants in order to maximize safety and minimize time and economic loss. These objectives include:

• maintaining the safety and integrity of operations on the airport,

• keeping the airport operational for all users to the greatest extent practical,

• minimizing delays for aircraft and construction operations, and

• maximizing airport operation and construction activity opportunities.

The “Team” must keep these objectives in mind when formulating work schedules and work activities affecting operations on the airport.

II. RESPONSIBILITIES OF THE CONSTRUCTION CONTRACTOR

The Contractor is responsible for supplementing and following the CSPP by way of the Safety

Plan Compliance Document (SPCD). See Appendix D for SPCD and Contractor requirements.

iii. Stockpiles are not permitted within the RSA while the runway is open.

iv. Excavations

40097.141.01 | February 2026 | Page 16 Century West Engineering

a. Open trenches or excavations are not permitted within the RSA while the runway is open. Excavations are to be backfilled before the runway is reopened.

b. If required by Airport Operations, construction contractors must prominently mark open trenches and excavations at the construction site with red or orange flags, as approved by the airport operator, and light them with red lights during hours of restricted visibility or darkness.

v. Soil erosion must be controlled to maintain RSA standards, that is, the RSA must be cleared and graded and have no potentially hazardous ruts, humps, depressions, or other surface variations, and capable, under dry conditions, of supporting snow removal equipment, aircraft rescue and firefighting equipment, and the occasional passage of aircraft without causing structural damage to the aircraft.

b. Runway Object Free Area (ROFA). Construction, including excavations, may be permitted in the ROFA. However, equipment must be removed from the ROFA when not in use. The proposed project does not allow stockpiling within the ROFA.

The Mulino State Airport ROFA has the following dimensions:

Runway 14-32: 250’ in width and 3,905’ in length minimum

500’ in width and 4,025’ in length (Current Design)

c. Taxiway Safety Area (TSA). A taxiway safety area is a defined surface alongside the taxiway prepared or suitable for reducing the risk of damage to an airplane unintentionally departing the taxiway.

The Mulino State Airport TSA has a width of 49’ (79’ Current Design).

Construction activities within the TSA are subject to the following conditions:

i. No activity (including construction) may occur within the TSA of WA#1 while the taxiway is open for aircraft operations.

ii. The TSA width will not be adjusted for the proposed project.

iii. Excavations

a. Open trenches or excavations are not permitted within the TSA while the taxiway is open. Excavations are to be backfilled before the taxiway is reopened.

40097.141.01 | February 2026 | Page 17 Century West Engineering

b. If required by Airport Operations, construction contractors must prominently mark open trenches and excavations at the construction site with red or orange flags, as approved by the airport operator, and light them with red lights during hours of restricted visibility or darkness.

iv. Soil erosion must be controlled to maintain TSA standards, that is, the TSA must be cleared and graded and have no potentially hazardous ruts, humps, depressions, or other surface variations, and capable, under dry conditions, of supporting snow removal equipment, aircraft rescue and firefighting equipment, and the occasionally passage of aircraft without causing structural damage to the aircraft.

d. Taxiway Object Free Area (TOFA). Unlike the Runway Object Free Area, aircraft wings regularly penetrate the taxiway object free area during normal operations. Thus, the restrictions are more stringent. No construction may occur within the taxiway object free area while the taxiway is open for aircraft operations.

The Mulino State Airport TOFA has a width of 89’ (131’ Current Design).

e. Obstacle Free Zone (OFZ). Personnel, material, and/or equipment may not penetrate the OFZ while the runway is open for aircraft operations.

The Mulino State Airport OFZ has the following dimensions:

Runway 14-32: 250’ in width and 3,825’ in length minimum

400’ in width and 3,825’ in length (Current Design)

Runway Approach/Departure Areas and Clearways. All personnel, materials, and/or equipment must remain clear of the applicable threshold siting surfaces, as defined in

Appendix 2, “Threshold Siting Requirements,” of AC 150/5300-13B, latest addition and changes.

18. Other Limitations on Construction

a. Prohibitions

i. No use of tall equipment (cranes, concrete pumps, etc.) unless a 7460-1 determination letter is issued for such equipment. A determination letter will be issued approximately 90-120 days after submittal of Form FAA 7460-1.

ii. No use of open flame, welding, or torches unless fire safety precautions are provided and the airport operator has approved their use.

40097.141.01 | February 2026 | Page 18 Century West Engineering

iii. No use of electrical blasting caps on or within 1,000 ft. (300 m) of the airport property.

iv. No use of flare pots within the AOA.

b. Restrictions. The Notes and Details shown on the attached Site Work Area and Safety

Plan offer additional details on restrictions on which areas cannot be worked in simultaneously, day/night work restrictions and other limitation
