§ 18.40.070. Site design.

Site design development standards in the IP district are as follows:

A.

Goals; Physical Barriers; Sight Lines.

1.

Preservation of existing stands of mature native and naturalized vegetation, existing views and significant land forms shall be primary goals in site plan development and site preparation.

2.

Coordinated site design including, but not limited to, shared parking and circulation systems, sign facilities, landscaped areas and garbage collection facilities are encouraged on adjacent parcels with similar uses.

3.

Physical barriers such as fences, curbs or walls between adjacent parcels with similar uses are prohibited unless needed for security purposes. When fences are approved, their design shall utilize materials consistent with those used on the existing or proposed structures.

4.

Clear sight lines between roads and railroad tracks shall be maintained; and

5.

Optimum solar access shall be provided.

B.

Driveways.

1.

Future driveways and driveway expansions shall be as provided for in the airport industrial area specific plan.

2.

No new driveways or driveway expansions shall be permitted off Highway 29.

3.

New driveway access off Airport Blvd. shall be prohibited except as provided for in subsection (a) below.

a.

A single new driveway access may be permitted by the commission for access to future support commercial facilities.

C.

Pedestrian Path Systems and Bicycle Parking Areas. Pedestrian pathways and bicycle parking areas shall be required.

D.

Taxiways. Taxiway access between airport runways and parcels adjoining the Napa County airport may be installed. Said access, which must comply with FAA regulations on "through-the-fence" operations, shall consist of at least ninety-three-foot-wide taxiway easements. Said easements shall be located so as to avoid crossing or intersecting internal streets. Special signals and gates shall be installed at all taxiway crossings of rail lines.

E.

Railroad Lines.

1.

Existing access to railroad lines shall be maintained. Except where the site development plans show no warehousing or manufacturing uses, at least twenty-foot-wide easements with three hundred foot turning radii for future "spur" rail lines shall be dedicated by those persons proposing to divide parcels with existing rail frontage. Said easements shall be situated so as to allow the provision of rail service to each new parcel formed.

2.

No additional railroad crossings of arterials or collectors beyond those shown in any applicable specific plan shall be allowed.
