About $8 million has been allotted for road reconstruction in Simi Valley as part of the city's 2007-08 budget, city officials said.

As early as next spring, parts of Sinaloa Road, Royal Avenue, Madera Road and Yosemite Avenue will be repaired, as well as residential areas near Sycamore Drive at Alamo Street, Sequoia Avenue at Los Angeles Avenue, and Erringer Road at Los Angeles Avenue, authorities said.

The construction will last through summer, ending in the fall.

"Areas that are badly deteriorated will receive the most reconstruction," said Kamran Panah, principal engineer of capital projects.

By taking an inventory on the conditions of all streets at least once a year, capital project engineers use a rating system to establish which roads need the most improvements, and how soon the improvements should be made.

"We prioritize the streets based on surface conditions," said Panah. "Then we use the collected data and determine the best treatments."

Engineers are using a relatively simple design for each project, said Ron Fuchiwaki, assistant director of Public Works. They will be laying 1.5 inches of new asphalt over the existing roads.

"The complete overlay, or resurfacing, will be done in late spring or summer (of 2008)," he said. "Typically, we try to resurface when the weather's warm, and when it will have less of an impact on schools in the area."

By choosing a time of year when the weather is warmer, engineers can ensure that the paving is done well, Panah said. "Temperature is very important. If it's too cold, you won't get a good quality paving job."

Authorities said they won't close entire streets. Instead, they will pave the roads in segments.

"It will generally be done during the day, depending on roadway and traffic conditions," Fuchiwaki, said. "We try to minimize the impact of construction on traffic."

Construction costs have increased in the past four years because of the high demand for new housing, as well as the rising cost of fuel and labor, Fuchiwaki said. However, he said the amount budgeted for the project will be enough to finish by early next fall.

"Based on the budget, we cluster the residential areas, because it's more cost effective than working on just one street at a time," Panah said.

The project will be funded by various sources, including the Community Development Agency, which is providing as much as $2.4 million.

More than $1 million from last year's budget is being carried over, while $786,000 will come from the general fund and $587,500 from Community Development Block Grants.

County, state and federal funding will provide $1.7 million.
