Disney Co. Plans Would Affect 6 Anaheim Streets : Expansion: Westcot Center would mean ‘short-term’ noise and air-quality problems, planners say. Huge parking garages are proposed.

Disneyland’s proposed $3-billion Westcot Center expansion calls for six city streets on the theme park’s perimeter to be realigned or eliminated, and is expected to create “short-term” deterioration of noise levels and air quality in the area, according to information provided to city planners Thursday.

Details of the entertainment company’s plan also indicate that two parking structures to serve the 470-acre expansion would rise 65 and 75 feet high--up to seven stories--while a new 98-acre lodging district would include three new hotels with about 3.9 million square feet.

The city is required to inform the public of its intention to study the local environmental effects of the planned development.

The study, expected to outline the project’s effect on local water quality, use of hazardous materials, growth, employment, land-use and other environmental concerns, could take nearly a year to complete, city officials said.

In addition to a giant golden dome called Spacestation Earth, other prominent elements of Westcot could dramatically change the look of Ball Road, Convention Way, Clementine, West and Walnut streets and Freedman Way.

According to the development’s master plan, West Street--now an unobstructed thoroughfare on Disneyland’s western boundary--would be transformed into a gently curving and landscaped boulevard that would serve the project’s hotel district. The company’s plan also calls for the street to be renamed Disneyland Drive.

On Walnut Street, just west of West, planners foresee a heavily landscaped area with trees and lush vegetation to provide a buffer zone for the residential neighborhoods bordering the project.

Disney officials said only Convention Way, located just south of the Harbor Boulevard and Katella Avenue intersection, could be eliminated in part.

Kerry Hunnewell, Disney Development Co. vice president, said changes to Convention Way, which serves the city’s convention center complex and surrounding hotels, could limit access across Harbor Boulevard. However, Hunnewell said the changes to Convention Way would occur only if the company proceeded with its “long-term” expansion plans, which involve the acquisition of a 58-acre strawberry farm located southeast of the Harbor-Katella intersection.

One of the farm’s owners, Hiroshi Fujishige, has rejected Disney’s offers to buy the property.

Disney’s master plan, including its intention to reconfigure city streets, would require City Council approval.

“In a report like this, you have to consider any possible eventuality to cover any environmental impact that could be created,” Hunnewell said. “This is very broad, but there will have to be improvements to the roadways.”

Of the noise and air pollution concerns, the city reported that “short-term odor impacts from diesel . . . equipment could also occur during construction.” For purposes of the study, city officials said, air quality and noise tests will be required.

According to the city’s public notice, parking structures for the area will include one giant building straddling Freedman Way east of Disneyland and capable of storing 16,200 vehicles on 51 acres. The structure, originally reported as two separate buildings, would have seven levels and be 75 feet high.

On the northwest side of the project, a six-level, 65-foot-high parking structure is planned on 26 acres, officials said. It would hold about 15,600 vehicles.

Disney has indicated that it wants the city of Anaheim to purchase the property for the east parking area and to build both structures.

For the city, acquisition of the 51 acres needed for the east structure could prove expensive. Land in the area has been valued at more than $1 million an acre. The entertainment company owns the land planned as the site for the northwest parking area.
