BALLSTON — In what could be the first of many projects on the site, a housing development at Route 67 and East Line Road will be considered this week by the Ballston Planning Board.

Developer Harold Schultz has filed plans for 21 townhouses for the site. Schultz received Ballston Town Board approval last year for a project that would mix residential, retail and business space at the intersection across East Line Road from the town of Malta.

In all, East Line Commons is approved for 210,000 square feet of offices, retail development and 21 units of either single-family, apartment or townhouse dwellings on 41 acres. The land, across from a Stewart’s shop, was previously zoned for industrial use.

The first phase of the project, according to plans filed with the town, would be construction of 21 townhouses and a common area lot on 4.4 acres.

The housing units would be constructed in four buildings on the northwest corner of the lot.

It is anticipated up to 53 people would occupy the units.

Before the town gave its approval to the overall residential and commercial development of the land, an architect for Schultz said the plans could create 400 to 450 jobs when completed and add $35 million to the Ballston tax base.

The Planning Board will consider the first phase on Wednesday.

Another project under consideration is for a one-story office building at the corner of Church Avenue and Ballston Avenue near the Ballston Spa village line.

Thomas Wallace Sr. is proposing a 7,200-square-foot building for professional offices.

Wallace has a similar building in use next door to the proposed site.

“[The new building will be for] clean professional type tenants,” according to the plan.

Also during the Planning Board meeting, a plan to move a nursery school into a private home on Lake Hill Road will be under consideration.

Jodie McClernan runs the Montessori School of Schenectady, which was located in the Hostetter Building of the Burnt Hills-Ballston Lake School District until two weeks ago when a water main break flooded the building.

That building, on Cypress Drive in Glenville, is expected to be closed for repairs for several months, according to school officials.

McClernan said her nursery school has two sessions a day, with each program running just under three hours. Some of the children are bused from elementary schools in the district.

She is proposing holding her programs in her home at 124 Lake Hill Road, and states the backyard will be fenced in and playground equipment will be erected for the children.
