Kennewick's strategy for developing the Southridge area includes extending major roads -- at taxpayer expense.
Hildebrand Boulevard and the Steptoe Street extension are top city council projects, said City Manager Marie Mosley.
Kennewick is using its own money and $6.7 million in grants to help push the road projects.
"We're very aggressive in applying for grants. Without them we wouldn't be able to do this," said Peter Beaudry, director of municipal services.
The Steptoe extension from Center Parkway to Fourth Avenue has $2.7 million from the state's Transportation Improvement Board and $1.2 million from federal gas tax funds. The remaining $500,000 will come from the city's general fund.
That means construction can begin in May on a part of Steptoe that wasn't even listed as a funded project last summer, Beaudry said.
Also on the city's to-do list is extending Hildebrand Boulevard to Sherman Street using money provided through the city's participation in Local Revitalization Funding.
The city gets $500,000 a year from the state in return for increases in sales tax and property tax revenues earned from Southridge development. The annual money returned by the state covers $13.6 million in construction bonds that will pay for the road and infrastructure improvements at Southridge.
Beaudry noted work on that part of Hildebrand will start in early 2013 and include installing water and utilities.
The city opened bids this week on another portion of Hildebrand, from Sherman Street to Southridge Boulevard. That, too, will rely on local revitalization funding and will begin immediately and is scheduled to be completed by the end of October.
Developers with property fronting both portions of Hildebrand must build two more traffic lanes as they develop their land, making Hildebrand a four-lane thoroughfare.
But the biggest road improvements in Southridge involve Ridgeline Drive and Southridge Boulevard.
Beaudry said bids will be advertised Tuesday for what is expected to be $3 million worth of work, using the revitalization money.
The project will improve and widen Southridge Boulevard from Hildebrand south to past Ridgeline; extend Ridgeline from Highway 395 to 36th Avenue at Southridge High School; extend Plaza Way from Hildebrand to Ridgeline; and improve Hildebrand from Southridge to Plaza Way.
There will be new roundabouts on Ridgeline at Southridge and at Plaza Way and traffic signals on Hildebrand at Southridge and Plaza Way.
All of the roadwork scheduled for this year will include installing water, sewer and storm drain facilities.
