A developer in Deer Valley on Wednesday night secured a one-year extension of the permit for his project, convincing a City Hall panel to allow the additional time for work to progress at the site over the objections of someone who lives in the vicinity.

The Planning Commission sided with City Hall staffers and granted the extension of the North Silver Lake permit for an additional 12 months. Lisa Wilson, who lives on Silver Lake Drive approximately 300 feet from the project site, had appealed to the Planning Commission the staff-level decision agreeing to the extension.

The Planning Commission denied Wilson’s appeal on a 3-0 vote. The permit was set to expire on July 1. The extension puts the date at July 1, 2012.

The overall permit allows the developer, Los Angeles-based Regent Properties, to put 54 units on the property, with the project envisioned as a mix of houses, duplexes and condominiums. The property is located close to the Evergreen and Bellemont neighborhoods.

There has been little apparent interest in the project by rank-and-file Parkites, but it caused a stir among some people who live or own properties in the vicinity. Work had commenced at the site, but it was later halted amid the faltering economy. The developer left a large hole on the property where digging had started in anticipation of construction.

Nobody spoke to the Planning Commission except Wilson, her attorney and a representative of Regent Properties. Others in the room, though, appeared to be interested in the discussion.

Wilson’s attorney, Matthew Muir, claimed there were inaccurate calculations regarding the amount of land that would be kept undeveloped and argued that the overall permit for North Silver Lake was modified as well as extended.

City Hall staffers disagreed with Muir’s assertions. Charlie Wintzer, the chairman of the Planning Commission, halted Muir’s discussion, indicating the appeal was limited to the extension instead of the broader development issues at the site. Muir objected to Wintzer’s refusal to hear a broader discussion.

Some of the Planning Commissioners either commended Wilson’s efforts or sympathized with her but said the panel’s role was limited in the case of the appeal.

In an interview after the vote, a Regent Properties representative said work is ongoing to restore the site before decisions are made about the development timeline. Richard Lichtenstein said the developers are replanting the land and refilling the hole with dirt. The area where the hole is located will be replanted once it is filled, he said, anticipating that work will occur in the middle of June.

Lichtenstein said the development timeline will be clearer at the end of the year. It will be based on the real estate market at the time, he said.

“We’d prefer to defer another year, until there’s a little more clarity in the real estate marketplace here,” he said.

Lichtenstein left open the possibility of requesting another extension of the permit after the current one expires in July 2012.

Wilson said afterward she was unsure whether she would appeal the Planning Commission’s decision to the City Council.
