Pittsburgh's Zoning Board of Adjustment has scheduled a July 31 hearing to try to address a property owner's bid for approval for a series of illegal Uptown parking lots, amid concerns that the neighborhood could face permanent islands of asphalt.

Sal Williams Real Estate operates several parking lots along Fifth Avenue. Some are reserved for University of Pittsburgh Medical Center employees, according to signs posted on chain link fences surrounding them.

According to zoning records, seven lots totaling 212 spaces have no permits, four lots totaling 214 spaces have permits for fewer spaces than are actually being used, and the company wants permits for four new lots totaling 154 spaces.

To operate legally, the lots need zoning variances or special exceptions. Zoning records indicate the company also has six lots that have the proper permits.

Councilwoman Tonya Payne, who represents and lives in Uptown, said she is involved in talks seeking a memorandum of understanding between the community and the company. Citizens want lighting, fencing and landscaping on the sites, and assurances that the parcels will not remain parking forever.

"For me, they're only temporary lots," said Ms. Payne. "What Sal's trying to do is use these as temporary lots until such time as development can happen."

She said the company and community are "close to actually reaching a deal," and may have the details worked out by the end of July.

Tony Williams of Sal Williams Real Estate could not be reached by phone or e-mail.
