The Airport Overlay Zone (AO) classification is intended to regulate land uses in areas adjacent to the Tracy Municipal Airport in order to:

(a)

Prevent the construction or establishment of any object which could become an obstruction to safe airport operation;

(b)

Prevent the construction or establishment of uses which would cause public assembly or occupancy of persons in the critical airplane approaches to the airport; and

(c)

Prevent the construction or establishment of uses which would adversely affect aircraft approach areas within the City limits.

(Prior code § 10-2.2701)

For the purposes of this article, unless otherwise apparent from the context, certain words and phrases used in this article are deemed as follows:

(a)

"Airport Reference Point (ARP)" shall mean 191 feet (USGS Datum).

(b)

"Approach surface" shall mean a surface longitudinally centered on the extended runway center line and extending outward and upward from each end of the primary surface. The inner edge of the approach surface is the same width as the primary surface, and it expands uniformly to a width of 1,250 feet, at a slope of twenty (20) to one, to a horizontal distance of 5,000 feet.

(c)

"Conical surface" shall mean a surface beginning at an elevation of 341 feet and extending for a radius of 4,000 feet at a twenty (20) to one slope beyond the radius of the horizontal surface.

(d)

"Horizontal surface" shall mean a surface 150 feet above the airport reference point, final elevation of 341 feet, the perimeter of which is created by rotating arcs with a radii of 5,000 feet from the center of each end of the primary surface runways of the airport and connecting adjacent arcs with lines tangent to those arcs.

(e)

"Primary surface" shall mean a surface longitudinally centered on the runway, extending 200 feet beyond the hard surface of the runway. The width of the primary surface is 500 feet.

(f)

"Transitional surface" shall mean a surface extending along the center line of each runway and establishing a final elevation of 341 feet using a slope of seven (7) to one.

(Prior code § 10-2.2702)

Any use permitted or conditionally permitted in underlying zones shall be permitted or conditionally permitted in the AO Zone, except where such use conflicts with the following:

(a)

Uses not permitted.

(1)

Uses in the following Use Groups, as defined in Section 10.08.1050 of Article 5 of this chapter, shall not be permitted in the inner 5,000 feet (as measured from the end of the primary surface) of the approach surface: 2, 4, 20, 21, 21.1, 22, 23, 24, 25, 26, 27, 30, 31, 32, 39, 40, 41, 42, 43, 48, 49, 62, and 63.

(2)

The following uses shall not be permitted in the inner 5,000 feet of the approach surface:

(i)

Residential developments;

(ii)

Hotels and motels;

(iii)

Restaurants and bars;

(iv)

Schools, hospitals, and governmental services;

(v)

Concert halls, auditoriums, and festival activities; and

(vi)

Uses which cause or encourage public assembly. (b) Conditional uses permitted. The following conditional uses shall be permitted in the inner 5,000 feet of the approach surface, subject to the provisions of Sections 10.08.4250 through 10.08.4420 of Article 34 of this chapter: uses in the following Use Groups as defined in Section 10.08.1050 of Article 5 of this chapter: 44, 45, 46, 47, 50, 51, 52, 53, 60, and 61.

(c)

Density coverage limits.

(1)

The maximum structural coverage shall be less than twenty-five (25%) percent of the net lot area in the inner 5,000 feet of the approach surface.

(2)

The maximum density in the inner 5,000 feet of the approach surface shall be limited to twenty-five (25) people per acre.

(d)

Fire hazards. No industry involved in flammable materials or processes shall be permitted in the inner 5,000 feet of the approach surface.

(e)

Height limits. No structure or appurtenance to a structure may be erected or added to, nor any tree planted or allowed to grow to, a height which intrudes into the horizontal, conical, transitional, or approach surfaces as defined in Section 10.08.3610 of this article.

(f)

Noise limits. No noise sensitive use as defined in the General Plan shall be permitted within the 1997 60 DB Noise Contour Line of the airport without sound attenuating construction practices.

(g)

Flight hazards. No use shall be permitted which will attract migratory or non-migratory flocks of birds.

(h)

Communication interference. No use shall be permitted which creates interference with radio communication or the radar between the airport and aircraft, or makes it difficult for pilots to distinguish between airports or airport lights, or results in glare, or impairs the visibility of persons using the airport.
