Hill Planning Area
| The Hill Planning area is east of Route 680 and Mission Boulevard, from Milpitas to the Union City limit. It includes Niles Canyon, Mission Pass and the Mission Hills but excludes a small area at the mouth of Niles Canyon and at the base of Mission Pass. It includes land outside of the Citys boundaries tot hedge of the publicly owned watershed lands owned by the San Francisco Water Department. The area can be divided into seven distinct units as shown in the separate Hill Planning Area map and described below.
Base of the Hills. This area is the area below the toe of the hill. The area is between Mission Boulevard(and I-880) and a line which demarks the beginning of steeper hills. The demarcation line is called the toe of the Hill and is defined as a line along the base often hills along which the natural grade is a maximum of 20npercent. The Base of the hills is the most easily developed portions of the Hill Planning Area and most of this area is developed. The provisions of the Hill Imitative do not regulate this area.
The Hill Face. This are is perhaps the dominant element of the Citys visual and physical character. The Hill Face extends from the Toe of the Hill to the Ridgeline. The Ridgeline is defined as the visual ridge as seen from Mission Boulevard, I-680 and other locations. The Ridgeline is shown on a separate Hill Planning Area map. Development of the Hill Face is also a relatively constrained area for development, with special geologic constrained area for development, with special geologic constraint sand unique biological resources. At the time(1990) there are only a few houses located on the Hill Face.
Niles Hills. This is a wedge of land east of the hill face and north of Niles Canyon extending to the Union City limits. This area is a mix of steep terrain and some rolling hills and is undeveloped.
Mission Hills West. This area is bounded by Mission Boulevard, the south branch of Mission Creek, Freeway Route 680, Durham Road and Paseo Padre Parkway. The principal topographic features of the area are three ridges formed by the erosive action of streams. The area is largely developed with a mixture of low density semi-custom homes, clustered residential development, the undeveloped Antelope Hills trail park, ad dedicated open space.
Vargas Plateau West. This area extends easterly from the visible ridgeline to the Citys eastern City limits, and extends north from I-680 to the steeply sloped land dropping off to Niles Canyon. The Vargas Plateau includes area of rolling hills and relatively flat terrain as well as highly constrained, steep slopes and biologically sensitive creek area. This are area has approximately 25 homes(1991).
Vargas Plateau East. This area is physically part of the Vargas Plateaus but outside of the Cotys existing boundaries. The subarea extends from the Citys boundaries to land owned by the San Francisco Water Department.
While physically part of the Plateau, the Vargas Plateau East area straddles two watersheds. On the east side of the watershed boundary, water drains into the Sunol Valley and becomes part of the San Francisco Water Departments Alameda Creek water supply(part of which is used by the City of Fremont). On the west side of the watershed boundary, water drains into the City, mostly into Mission Creek and another creeks which do not affect Alameda Creek or the Citys water supply.
Mission Creek. The are east of the visible ridge and south of I-680 is referred to as the Mission Creek area. The Mission Creek Area is considerably more rugged that the Vargas Plateau; much of this area includes slopes similar to the Hill Face. This area has only a few homes.
Sheridan Road. South of I-680 is another area extending southwest from the Sunol Valley. Some of this area is an extension of the Valley with relatively flat land and rolling hills, while other areas are steeply sloped similar tot the portions of the Mission Creek area. Existing uses included nurseries and quarries, in addition to agriculture.
In addition to these areas, the Hill Planning Area also includes Mission Pass and Niles Canyon, tow routes through the hills which extend from Sunol Valley into Fremont.
The few roads serving the hills above the Toe Hill are mostly narrow. Only a small portion of the lower portions of the Hill Face are served with public sewer and water, and there is no sewer or water services at higher elevations or east of the Ridgeline. Almost all of the Hill Planning Area above the Toe of the Hill is outside of the area where the City can meet its objective of responding to emergencies within five minutes.
