The proposed East Ridge Business Park stepped closer to approval Tuesday with the developer gaining two advantageous rulings from the Amador County Board of Supervisors.

Construction costs for a stop light intersection at Ridge Road, Sweet Pea Way and a business parkway east of Sutter Creek need not be borne completely by East Ridge developers, supervisors held. The board upheld applicant Aaron Brusatori's appeal of the county planning commission's Dec. 9 decision to condition its approval of a project map.

"Development on the south side of Ridge Road triggers (stop light-level traffic conditions) with or without my project," Brusatori said a study showed.

Developers of the 9.7-acre East Ridge site will instead pay a yet-undetermined "fair share" of stop light construction costs, as will other major feeders of vehicle traffic to the intersection, supervisors agreed.

One of those is the recently completed Amador Transit Mix concrete plant. Another is a proposed Sweet Pea subdivision.

In addition, East Ridge Business Park proponents Tuesday won a supervisors' variance from one of a list of building setback requirements established by planning commissioners.

Charles Field, executive director of the Amador County Transportation Commission, told supervisors that planning is not finished for improvements at the Ridge Road-Sweet Pea Way intersection.

Computer modeling will be employed to assess data and project possible future traffic needs at the location - in conjunction with the county installing elements of a regional transportation plan, Field said.

Supervisors agreed improvement is needed. "That's a really bad intersection," said District 2 Supervisor Richard Forster.
