Haverhill City Councilors were beside themselves with praise for a plan, presented at Tuesday’s meeting, to construct three affordable townhouses at the corner of Washington and Ayer Streets in Haverhill. That property, at 462 Washington St., contains an abandoned hair salon once known as “Mr. Wayne Hairstylists” as well a large paved parking area. Attorney Donald F. Borenstein, representing property owner Richard P. Early Jr, began by telling councilors the planned building will be an excellent fit in the neighborhood. “Basically, in the immediate area of that building, we have approximately one-third of the buildings are two family homes and two-thirds of the buildings are either three family or four plus, so we believe the density of this as a three unit project is very appropriate for that neighborhood, a good use of that corner,” he said. Borenstein said the three townhouses will be side by side, each featuring three bedrooms and, at least, one parking garage per unit beneath the building as well as substantial off-street parking.
