Pillsbury Road is off the beaten track for most Manteca residents.

Up until 10 years ago it was a sleepy two-lane road that T-intersects with Woodward Avenue between Atherton Drive and Bridewell Avenue. That’s when two streets from two new neighborhoods were extended to Pillsbury Road and a landscaped median added for a short stretch.

Pillsbury Road also provided additional access point to the estate where the 30,000-square-foot Hat Mansion is located.

The semi-country feel of the fairly short road south of Woodward Avenue is about to change.

On Tuesday the Manteca City Council will consider hiring Raney Planning & Management to prepare environmental impact reports for three proposed housing projects that are proposed along Pillsbury Road that will add 1,156 homes.

They are:

• Atherton Homes Woodward Park I & II: These are two separate neighborhoods on 111.3 acres planned for 356 single family homes immediately north of the hat Ranch, west of Pillsbury Road, and west of the proposed southern extension of Atherton Drive south of Woodward Avenue.

• Hat Ranch Active Adult Community: It would convert 184 acres comprised mostly of grape vineyards into 800 age-restricted homes in a development almost half exactly half the size of Del Webb at Woodbridge in north Manteca. The 30,000 clubhouse — originally built as a mansion — would be slightly larger than its Del Webb counterpart. The clubhouse would be surrounded by softball fields, tennis courts and bocce courts. The Hat Ranch — now owned by Richland Communities — would have to be annexed to the city.

The three-story mansion has a wine cellar, elevator, a 25-seat theater, tennis court and 20- by-80 foot swimming pool. Completed in 1995, the home also has a 36-car parking garage underneath it. Material used in the interior design includes Brazilian cherry wood, Douglas fir, limestone, granite, marble and custom made stainless steel doors. It has six bedrooms and seven bathrooms.

The mansion was built by Michael Hat, a 1972 Ripon High graduate. He is a grape grower and broker. Hat at one time was ranked among the top five grape growers in California.

Richland will front the money for the EIR — $214,223 — to the City of Manteca. Atherton Homes will pay for the $175,383 study for its two new neighborhoods.

The consultant though will work for the city with Manteca using the funds provided by the developers to pay for the EIR work.

The City Council meets Tuesday at 7 p.m. at the Civic Center, 1001 W. Center St.
