Tehachapi: a guide to our communities

The modern development of Tehachapi began in 1876, when the railroad was completed. An earlier settlement, once called Williamsburg and now known as “Old Town” was founded in the 1860s and was an important station on the road between the San Joaquin Valley and Southern California. Old Town declined when residents gradually relocated to nearby Greenwich, the first name for the community now known as Tehachapi. The City of Tehachapi incorporated in 1909 and for many years was surrounded by ranchland. Development of ranches in the mid-twentieth century has continued and a number of unincorporated communities – all part of Tehachapi – have developed. These communities offer a variety of amenities with just about as much diversity as the natural surroundings.

Communities and developed areas (in addition to the City of Tehachapi) include:

Golden Hills/Old Town/Oak Knolls – residential and commercial development to the west of the City of Tehachapi within the Tehachapi Valley.

Alpine Forest Park/Mountain Meadows/Old West Ranch – residential developments in higher elevation areas south of the City of Tehachapi including forested land with many homes “off the grid.”

Brite Valley – area including small farms and residential lots of various sizes located between the Tehachapi and Cummings Valleys. Brite Lake – a reservoir which serves the Tehachapi-Cummings County Water District and is open to the public for fishing – is in this area.

Cummings Valley/Fairview Ranchos/Stallion Springs – the western-most area of Tehachapi – some portions overlook the San Joaquin Valley. The historic Cummings Ranch and California Correctional Institution are located here. Cummings Valley is a mix of residential development and intensive agriculture including commercial production of organic vegetables and Tehachapi’s two producing vineyards, as well as an ostrich ranch and alpaca ranches. Fairview Ranchos and Stallion Springs are residential subdivisions in the valley. Tehachapi’s only public golf course – the Horse Thief Golf and Country Club are located here, as is Woodward West, a nationally noted youth sports camp..

Bear Valley Springs – a gated community in Bear Valley which is accessed from Cummings Valley. Residents have use of facilities including the Oak Tree Country Club golf course, shooting range, swimming pool, lakes and horseback riding trails. These facilities are generally not covered in this guide because they are not open to the public.

NC Media Watch: New EPA rules will close down California Portland ...

California construction industry is on the ropes and has been a major contributor to the states high unemployment rate.  Now the EPA is posing new standard for boilers, titled “National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters” and called the Boiler MACT. It creates a new standard that literally no producer in the US meets at the moment, including the ten portland cement plants in California. The Attorneys General of the States of California, Delaware, New York, Oregon, Vermont, and Washington, and the Commonwealth of Massachusetts, submit these comments on the United States Environmental Protection Agency’s (EPA’s) proposed rule amending the current standards of performance for Portland cement plants, published at 73 Fed. Reg. 34072 (June 16, 2008). The proposed rule does not propose any new source performance standards (NSPS) for greenhouse gas (GHG) emissions from Portland cement plants. It has been almost a year and a half since Massachusetts v. EPA, 549 U.S. 497, 127 S.Ct. 1438 (2007), confirmed that GHGs are air pollutants subject to regulation under the Clean Air Act. While this should have triggered EPA to propose new source performance standards for GHG emissions from a variety of sources, including Portland cement plants, EPA has not proposed any such standards for any source. Instead, EPA has issued an Advance Notice of Proposed Rulemaking (ANPR) that seeks public comment on whether to regulate GHG emissions under the Clean Air Act at all. (73 Fed. Reg. 44354 (July 30, 2008).) We protest this course of action, and request that EPA revise the proposed rule to include new source performance standards for GHG emissions. Well the EPA has decide that AG Brown was right, and they have published new standards that will shut down the cement production industry in California. Construction companies will now have to import cement from China. Jerry Brown's demads to reduce greenhouse gases are killing California Jobs and creating jobs in China.  Is this the kind of leadership that we are looking for in California? California construction industry is on the ropes and has been a major contributor to the states high unemployment rate.
