Project Title: Eagle’s Nest V and VI Aviation Business Park (Proposed Project). 2. Lead Agency Name and Address: City of Chino, 13220 Central Avenue, Chino, CA 91710. 3. Contact Person and Phone Number: Mr. Ryan Murphy, Planner, (909) 334-3525. 4. Project Location: Northeast portion of Chino Airport, 7000 Merrill Avenue, Chino, CA 91710. 5. Project Sponsor's Name and Address: Chino Development League, P.O. Box 8397, La Verne, CA 91750. 6. City of Chino General Plan Designation: Public.1 7. County Department of Airports Land Use Designation: Privately Leased Aviation Development Parcel. 8. Zoning: Airport Development.2 9. Project Description: The Eagle’s Nest V (Phase I) and VI (Phase 2) project proposes the development of an approximately 158,490 square-foot (sf) aviation business park generally occupied with executive hangars on an approximately 8.5-acre, unimproved site located in the northeastern quadrant of the Chino Airport (Figure 2—Eagle’s Nest V and VI Development Site).The proposed project hangars will be constructed with concrete tilt-up walls, concrete flooring, metal bi-fold doors, and wood and steel truss roofs. Tenants can construct improvements in compliance with existing code, including upper floors/mezzanines. The hangars are designed to provide the space requirements necessary to store and maintain executive (corporate) and multi-passenger aircraft at the Chino Airport. The proposed project will also include parking, landscaping, curbs, ribbon gutters and hardscape parkway improvements for the frontage street along Merrill Avenue, including a new driveway approach located at the northeasterly end of the proposed development. The proposed project will be developed in two (2) phases: Phase I—Eagle’s Nest V proposes the development of Buildings A and B. Building A includes 13 hangars varying in floor area from 3,300 sf to 4,800 sf, totaling 51,868 sf. Building B is a 23,008- sf hangar, including 3,028 sf of office space and mezzanine, and is designed for a commercial aircraft company that would provide services such as avionics update installation. The total area of Eagle’s Nest V is 74,876 sf (see Figure 3). Building A tenants are expected to store one to two aircraft per hangar. The Building B hangar occupant would store multiple aircraft for the duration of required service. Eagle’s Nest V hangar units will be constructed with metal bi-fold hangar doors on both the north and south to provide aircraft access from Taxiways N and R. Also, Eagle’s Nest V tenants will be able to taxi their aircraft (engines on) to their respective hangar doors on both the north and south. 1 City of Chino. General Plan Land Use Map.

Eagle’s Nest V and VI Aviation Business Park Project Initial Study 3 City of Chino Phase 2—Eagle’s Nest VI proposes the development of Buildings C and D. Building C contains six (6), 8,360-sf hangars, and Building D contains a 28,305-sf hangar, including 4,500 sf of mezzanine. The total area of Eagle’s Nest VI is 83,614 sf. Building C tenants are expected to store one corporate, multi-passenger aircraft per hangar. Building D is designed to store one large corporate jet such as a Gulfstream. Eagle’s Nest VI units will be constructed with metal bi-fold doors opening to the south only. Aircraft stored in Eagle’s Nest VI hangars will be required to shut off engines on Taxiway R, then be towed to their respective hangars. 10. Construction: The proposed project will be constructed in two (2) phases of approximately 6 months per phase. The project will be constructed in compliance with applicable municipal development code and building code, and in accordance with South Coast Air Quality Management District (SCAQMD) Rule 403, which requires that contractors implement Best Available Control Technology (BACT) during construction activities.3 11.
