Tell Me a Little Bit About Newbury Park

Newbury Park is a community located in the western portion of Thousand Oaks. Most of Newbury Park became part of Thousand Oaks by community vote sometime in the 1960s and 1970s. Thousand Oaks became a city in October 1964.

Newbury Park is named after Egbert Starr Newbury, who owned thousands of acres of land in the Conejo Valley after moving to California from Michigan for health reasons in 1871.  Newbury was one of the three largest Conejo Valley landowners of his time. He and his wife Fannie became the first postmasters in the Conejo Valley in 1875.  The post office was located in a small compound near their house, which was located at the current location of the Thousand Oaks Civic Arts Plaza. 

The other major landowners at that time were John Edwards, who owned much of the current Newbury Park/Thousand Oaks area north of the 101, and Howard Mills, who owned much of what today is Westlake Village and Hidden Valley.

Edwards sold 10,000 acres of what is now central Thousand Oaks to Edwin and Harold Janss in 1893.  The Janss Corporation also bought thousands of acres of land in Newbury Park (Friedrich, Running Springs and Borchard Ranches) in 1962. 

There were efforts to incorporate Newbury Park in 1961 and 1963 that failed due to a lack of sufficient votes.

Over a 30 month period beginning in the Fall of 1876, only 6 inches of rain fell in the Conejo Valley.  This drought brought devastation to landowners, most of whom lost their crops and livestock and had to sell at a loss or went bankrupt.  The Newburys were no exception; they moved back to the midwest in 1877.  Egbert fell ill to pneumonia in 1880 and passed away at the young age of 36.

The Newburys lived here only six years, so why is it still called Newbury Park? Because the name of the Newburys' post office never changed! The Newbury Park Post Office has changed locations a number of times (including 1602 Newbury Road from May 1968 until it moved to its current location at 3401 Grande Vista Drive in 2013). So the Newbury name and legacy live on here in the Conejo Valley.

But wait...there's more to Newbury Park! Casa Conejo is also part of the Newbury Park community but is not an incorporated part of Thousand Oaks. It is considered a census-designated place in Ventura County, with its own Municipal Advisory Council. Casa Conejo is the first planned community in Newbury Park and was built in the early 1960s. It is has an area of .5 square mile and is bound by Borchard to the South, Old Conejo Road to the North, Jenny Drive (East of Newbury Park High School) to the West and Sequoia Middle School to the East.

M*A*S*H Site at Malibu Creek State Park

Malibu Creek State Park is a wilderness wonderland, stretching over 8,000 acres in Calabasas, Agoura and Malibu. The park is a great place for hiking, biking, camping, picnicking and exploring. If you do plan to explore the park, be sure to check out the old M*A*S*H (or "MASH" television series set!

Produced by 20th Century Fox, M*A*S*H was filmed from September 1972 to February 1983 over 11 seasons and 256 episodes on CBS. Exterior scenes were filmed at what is now Malibu Creek State Park. Over the years, the ambulance and other props left at the old site became less and less visible as the surrounding brush became overgrown.

In 2007, the set was restored with a shaded picnic area, military vehicles, ambulance, helipad and signpost. Check out the photos below, but, better yet, visit it in person! For more pictures and extensive information about the M*A*S*H set and Malibu Creek State Park, visit www.malibucreekstatepark.org.

The M*A*S*H site is easily accessible from the main parking lot at Malibu Creek State Park, mostly on wide fire roads, with one significant hill, a bridge crossing and one somewhat rocky trail section. The path is about 2 1/2 miles each way, so it would be a good idea to bring drinks and snacks.

Erbes Road in Thousand Oaks Named After Early Settlers in the Conejo Valley

calisphere.org/item/ark:/13030/c8w093ww

This is Elizabeth Opper Erbes. She is the mother of Ernest and Otto Erbes, who were early settlers in the Conejo Valley.

Otto (born in 1885, passed in 1959) owned a walnut orchard on what is now Erbes Road.

Estella Park on Erbes Road just south of Hillcrest is located on land donated to the city by Otto Erbes and his wife.

Erbes Road is a major north/south artery in the City of Thousand Oaks, stretching just over 5 miles, from Calle Zocolo, north of Olsen Road, on the north, to Thousand Oaks Boulevard on the south.

Olsen Road is also named after early Conejo Valley pioneer Nils Olsen. Olsen and four Norwegian compatriots purchased 650 acres of land from George Edwards in 1890.

The Twin Ponds Conservation Area in the Conejo Open Space is Protected Land

The Twin Ponds Conservation Area in Dos Vientos is part of the open space lands of the Conejo Open Space Conservation Agency and is protected by a conservation easement to the California Department of Fish and Game.

The ponds were originally constructed in the 1920s as part of the irrigation system for agricultural and cattle ranching operations at Dos Vientos Ranch. Today they serve as important habitat for Two Striped Garter Snakes and larger animals such as deer, bobcat, coyote and mountain lions that depend on a reliable source of water. Migrating waterfowl are occasionally abundant, especially in winter.

COSCA and Fish & Game ask that we enjoy this scenic area but protect the ponds for the future and ask that we do not enter the water or allow dogs/horses to enter the water, disturb or remove any animal or plant or place any plants or animals, including fish, into the ponds.

To explore the ponds, take the Vista Del Mar Trail from one of several access points in the Dos Vientos area, including the corner of Via Ricardo and Via Rincon and the corner of Rancho Dos Vientos and Via El Cerro. This is a fun little hike to take the kids on and the ponds are only about a mile from the Via Ricardo/Via Rincon trailhead.

Twin Ponds? What ponds? The ponds are completely dried up as of August/September 2016.

Map From Westlake Master-Planned Community Brochure from 1968

View fullsize

In 1968, the American-Hawaiian Land Company, a division of American-Hawaiian Steamship Company, was developing the Westlake master-planned community, "the new city in the country."

At the time, 2,500 people lived in Westlake. The Ventura County sections of Westlake were annexed into the City of Thousand Oaks in 1968 and 1972. The Los Angeles County section of Westlake was incorporated as the City of Westlake Village in 1981. Some notable items from this 1968 map from a Westlake brochure:

1. "El Conejo Blvd." was later changed to Thousand Oaks Blvd.

2. Westlake Plaza did not exist at the time, though you can see "Future Town Center."

3. What is now Westlake Village Inn, Mediterraneo and Stonehaus back then was the Westlake Motor Hotel, Westlake Inn restaurant and Chauncey's Coffee House.

4. Last, but not least, there was no Costco in the original planned community map.

Evolution of the Conejo Grade in Ventura County Over the Last 100 Years

Horseshoe shaped section of the Conejo Grade in the 1920s.

The Conejo Grade is the section of Highway 101 that connects the Conejo Valley with Camarillo. It is a four mile stretch of freeway with a significant 7% grade.

Going down the Conejo Grade from Newbury Park to Camarillo today.

At 3:30 p.m. on the afternoon of May 1, 1937, a newly upgraded and realigned Conejo Grade premiered after a day of celebration commencing at the ranch of Adolfo Camarillo. Camarillo, the namesake of what in 1964 became the City of Camarillo, donated the right of way to enable the grade to be realigned. Actor Leo Carrillo entertained guests at Camarillo's ranch at the bottom of the grade.

Grand opening of the newly realigned Conejo Grade on May 1, 1937.

The old Conejo Grade was constructed by the California Highway Commission in 1914-1915. The previous route had 49 twists and turns, making it somewhat hazardous to drive (albeit somewhat less steep than the current grade). The newly aligned Conejo Grade cut the number of curves by 75%.

Another view of the Conejo Grade before it was realigned in 1937.

The new 1937 Conejo Grade cost a total of $570,000, which is less than the average cost of a house in the Conejo Valley today! Over a year and a half, the project employed about 100 workers who put in over 272,000 hours, excavating over 800,000 cubic yards of mostly hard rock. Talk about rock stars!

In the 1950s and 1960s, Caltrans further widened and improved Highway 101 over the Conejo Grade.

Several decades later, as Ventura County grew and the cities of Camarillo and Thousand Oaks incorporated in 1964, Caltrans continued to widen and improve the highway to what it is today.
