CRANSTON –– The Planning Department will hold a workshop Tuesday night to gather public comment on a prospective overhaul of the city’s Comprehensive Plan.

The plan, meant to guide development and open-space preservation, has not been updated since 1992.

The city has been working for several years to reshape the plan, with help from a consultant, The Cecil Group, a Boston planning and design firm.

The Planning Department collected public input through a mail-in survey in December 2004 and a series of workshops in 2004 and 2005.

But now that staff is making significant headway on a second draft of the document, said Peter Lapolla, the planning director, it is time for more.

“The goal of this is to get as much public comment as possible,” he said.

The workshop is scheduled for 7 p.m. Tuesday in the City Council Chamber of City Hall, 869 Park Ave. Lapolla said it will be the first of several.

The first meeting will focus on the housing, natural resources and open-space portions of the Comprehensive Plan.

Save Cranston’s Open Space, a citizens group that helped to kill a shopping center project on the site of the Mulligan’s Island golf complex last year, is mobilizing neighbors to attend the hearing and advocate for continued restrictions on development of the land.
