Two controversial development proposals for northwest Lawrence are back on the Lawrence-Douglas County Planning Commission agenda this week.

Rezoning and plans for a Wal-Mart Supercenter — smaller than the first, failed proposal — will be considered for Sixth Street and Wakarusa Drive. So will revised zoning and plans for a residential development at Sixth Street and Folks Road that ran into roadblocks last year.

And while developers have changed both proposals to answer the objections that killed them the first time around, the battles aren’t over. Neighborhood residents and community organizations have written dozens of letters opposing the developments.

In the case of Wal-Mart, some opposition on the planning commission remains.

During an agenda study session Monday, Commissioner Ernie Angino noted developers already had permission to build a store of roughly 130,000 square feet in size on the site. The new proposal asks permission to build a 158,000-square-foot store.

Under the original plan, the entire store space would have occupied 199,000 square feet. The planning commission rejected that proposal last fall.

“It seems to me that any request over that is playing games with the commission,” Angino said of the 130,000 square feet of approved space. “They know what they can do, and they’re asking for more.”

But the proposal has a positive recommendation from city planners, who said it conformed to the city’s comprehensive plan and wouldn’t overwhelm the nearby intersection with traffic. Advocates point out the store would have special architectural features.

“It’s better than the typical big box,” planner Bryan Dyer said.

The proposal for an apartment complex at Sixth Street and Folks Road failed last year when neighbors filed a protest petition, which would have required a 4-1 supermajority vote of the city commission to approve development. Neighbors said they wanted development similar to their single-family neighborhood.

The new proposal includes single-family housing to act as a buffer with the neighborhood, but opponents say the changes aren’t good enough. The Quail Run Neighborhood Assn., the League of Women Voters and the Lawrence Association of Neighborhoods have all registered objections.

Also on Wednesday’s agenda: a request for a conditional-use permit to begin quarry operations near Eudora. Neighbors object to that proposal.

The commission meets at 6:30 p.m. Wednesday in City Hall, Sixth and Massachusetts streets.
