The purpose of the airport environs (AE) overlay district is to regulate land use and development within the Nut Tree Airport compatibility areas and the Travis Air Force Base area of influence consistent with the adopted land use compatibility plans. The Nut Tree Airport and the Travis Air Force Base Airport, also referred to as Travis Airport, are important to the economic prosperity of the City. Consideration must be given to the operations of the Nut Tree and Travis Airports when development is proposed in order to ensure that a compatible balance of uses is maintained. The provisions of this chapter are established to achieve the following purposes:

A. To provide for the safe and orderly development of the Nut Tree Airport and the Travis Air Force Base by protecting users of the airport from hazardous encroachments into areas of navigation operation and preventing the creation of hazardous encroachments into defined airspaces;

B. To ensure the continued viability of the Nut Tree Airport as a general aviation facility and protect the substantial public investment in the facility;

C. To ensure the continued vitality of Travis Air Force Base as a military facility and to protect the substantial public investment in the facility;

D. To comply with the requirements of the California Public Utilities Code to protect the public health, safety, and welfare by ensuring the orderly expansion of airports and minimize the public’s exposure to excessive noise and safety hazards within areas around public airports to the extent that these areas are not already devoted to incompatible uses;

E. To implement the policies of the Nut Tree Airport Land Use Compatibility Plan, adopted May 20, 2010, and the Travis Airport Land Use Compatibility Plan, adopted June 13, 2002, by the Solano County Airport Land Use Commission (ALUC);

F. To protect persons and property in the vicinity of the Nut Tree Airport and the Travis Airport from unreasonable hazards or impacts associated with airport operations; and

G. To implement the goals, objectives, and policies of the General Plan.

14.09.110.040 Height Limitations.

The maximum height of any structure or object shall be such that no penetration of the applicable air space surface occurs.

A. Nut Tree Airport Compatibility Areas. The height limits are established consistent with FAR Part 77 surface identification for the Nut Tree Airport. For purposes of determining these heights, the U.S. Coast and Geodetic (based) Survey has established the runway elevation reference for the Nut Tree Airport to be 113 feet.

1. Maximum Height. No structure or object shall be erected, altered, maintained, or allowed to grow in excess of the height limit established for the airspace surface area in which the property is situated except as provided below.

a. In Compatibility Areas A, B, and C, an exception to the maximum height limits may be approved provided the decision maker determines that no reasonable use of the property is possible if the height limitations are strictly interpreted.

b. In Compatibility Areas D, E, and F, airport height limits shall not be less than 35 feet above the ground level.

2. Determination of Maximum Height. To determine the airport height limit for a specific location on a site within the airport compatibility area, it is necessary to determine the elevation of the point on the applicable airspace surface that lies directly above the location in question.

a. For the primary surface and the horizontal surface, the elevation of the entire surface is established as 113 feet and 263 feet, respectively.

b. For the transitional, approach, and conical surfaces, the elevation is a function of the horizontal distance from the primary surface and the slope of the applicable surface. For example, a location underlying the approach surface at the north end of the runway that is 5,000 feet from the primary surface, would have a maximum height limit of 213 feet above sea level. The 5,000 feet distance at a slope of one foot vertical for each 50 feet horizontal results in an increase of 100 feet over the primary surface elevation of 113 feet.

3. Surface Areas.

a. Primary Surface. “Primary surface” means a surface at an elevation of 113 feet longitudinally centered on the airport runway and extending beyond the end of a runway. The primary surface at the Nut Tree Airport is 1,000 feet in width and extends 200 feet beyond the end of the south end of the runway (Runway 2) and the end of the planned extension of the north end of the runway (Runway 20).

b. Approach Surface. “Approach surface” means the surface longitudinally centered on the extended runway centerline, extending outward and upward from the end of the primary surface at a defined slope. The approach surface at the Nut Tree Airport extends outward and upward from the end of the primary surface at a slope of 50 feet horizontally to one foot vertically for an initial distance of 10,000 feet and at a slope of 40 feet horizontally to one foot vertically for a distance of 40,000 feet thereafter at the north end of the runway (Runway 20) and at a slope of 34 feet horizontally to one foot vertically for a distance of 10,000 feet at the south end of the runway (Runway 2).

c. Transitional Surface. “Transitional surface” means the surface extending outward and upward from the sides of the primary surface and the approach surface at a slope of seven feet horizontally to one foot vertically to the intersection with the horizontal surface. The transitional surface at the Nut Tree Airport extends outward and upward from the primary surface and approach surface at a slope of seven to one to an elevation of 150 feet above the runway elevation or 263 feet mean sea level.

d. Horizontal Surface. “Horizontal surface” means a horizontal plane 150 feet above the established runway elevation extending from the intersection of the transitional and approach surfaces to the intersection of the conical surface with the horizontal surface. The horizontal surface at the Nut Tree Airport is 150 feet above the runway elevation of 113 feet extending out from the approach and transitional surfaces to the intersection with the conical surface at an arc radius of 10,000 feet from the center of each end of the primary surface of each runway.

e. Conical Surface. “Conical surface” means a surface extending outward and upward from the periphery of the horizontal surface at a slope of 20 feet horizontally to one foot vertically for a horizontal distance of 4,000 feet.

B. Travis Air Force Base Area of Influence. The established runway elevation for Travis Airport is 62 feet mean sea level.

1. Maximum Height. No structure or object which would be of a greater height than the outer horizontal surface of 562 feet mean sea level shall be erected, altered, maintained, or allowed to grow except that the construction of objects upon land which underlies the outer horizontal surface and which penetrates the outer horizontal surface may be allowed if they conform to FAR Part 77 height limits and filing requirements, and provided that a height limit easement is granted consistent with FAR Part 77.

2. Notification Requirement. Any proposed structure that would penetrate the 100:1 imaginary slope identified as “FAA Construction Referral Boundary (100:1)” shall comply with the notice and filing requirements of applicable federal and state regulations.

3. Outer Horizontal Surface. The outer horizontal surface is defined as a plane extending for a horizontal distance of 30,000 feet from the outer periphery of the conical surface, located 500 feet above the established runway elevation.

4. Height Review Overlay Zone. The following criteria applies developments within the height review overlay zone as listed in Section 4.9 of the Travis Air Force Base Land Use Compatibility Plan:

a. Airspace review required for objects greater than 35 feet AGL;

b. Avigation easement dedication required;

c. All proposed wind turbines must meet line-of-sight criteria in Policy 5.6.1 of the Travis Air Force Base Land Use Compatibility Plan;

d. All new or expanded commercial-scale solar facilities must conduct an SGHAT glint and glare study for Airport Land Use Commission review; and

e. For areas outside of the bird strike hazard zone (See Section 4.9, Travis Air Force Base Land Use Compatibility Plan), but within the outer perimeter, any new or expanded land use involving discretionary review that has the potential to attract the movement of wildlife that could cause bird strikes are required to prepare a WHA.
