An attorney for the Konterra development proposed for south of Laurel yesterday challenged arguments that the ambitious project would be incompatible with its neighbors, telling a Circuit Court judge that it would not be out of place in an area that already has a degree of commercial and residential development.

In addition, attorney Glenn T. Harrell Jr. said, construction plans would be reviewed several more times by Prince George's County planning officials. "Whatever is allowed to be constructed on this property will be compatible with the neighborhood," he pledged.

He presented his case in the second day of a hearing before Judge James M. Rea, who is presiding over lawsuits filed both by neighbors and the developer, Kingdon Gould Jr. Both sides have asked Rea to overturn the November 1984 County Council decision rezoning 523 acres at the Konterra site, which straddles Rte. I-95 between Laurel and Beltsville.

The hearing concluded yesterday. The judge did not indicate when he might render a decision.

Opponents of the Konterra project, more than two dozen homeowners who are represented by attorney Jess Joseph Smith Jr., argued Monday that the development of homes, office and commercial buildings would be incompatible with the residential neighborhoods nearby. Also, Smith said, highway and other facilities are not adequate; the "mixed use" zoning granted for 488 acres, he argued, lacks sufficient controls on design and development.

But Harrell countered that approvals required down the line constitute "a fairly comprehensive approach to making sure nothing slips through the cracks." Also, there is a "reasonable expectation" that a highway will be built nearby, he said.
