Raleigh growth in the future should be focused on several specific areas of high-density growth under a plan adopted by the Raleigh City Council Tuesday.

City officials said the 2030 Comprehensive Plan will focus city growth on downtown and seven main city hubs.

The plan includes a color-coded map defining what type of zoning each area of the city should follow.

Mayor Charles Meeker said they hope to curb sprawl in outlying areas of the city and create more density and mixed-use development in areas of the city such as downtown, North Hills and around the state fairgrounds.

The plan also includes potential uses for trains and expanded bus systems.

Meeker said North Hills, a mixed-use area of residences and retail, is a good example of what the city is hoping to achieve.

"Over time using more of the rural land doesn't make sense," he said. "Also it's far less expensive to have people living and working near each other. The cost of putting in roads is very high."

Two areas of the city were not approved with the plan - both in the West part of Raleigh. Both will undergo further study before a decision is made.

One, around West Morgan and Hillsborough Streets downtown, requires a deeper look at how to blend neighborhoods with downtown, said Raleigh Councilman Thomas Crowder.

The other, an area around Western Boulevard and Jones Franklin Road will be studied for possible road path improvements, he said.

Most of the plan remains the same as it was suggested earlier this year. Crowder suggested more than 50 revisions based on reaction he received from residents in his district. Most of those changes were approved by the council.

The council will review final edits and revisions in October. The plan will take effect Nov. 1.
