A developer has proposed replacing the North Coast Seafood processing plant at 270 West 2nd St. with a 93-unit residential building that will start at four stories along the residential West 2nd and rise to six stories along the industrial West 1st.
P. Christopher Associates, a Cambridge firm owned by the family of longtime Boston news executive Phil Balboni, told the BPDA this week it will shortly file detailed plans for its proposal, which it says will include taking down an "unsightly" billboard at the site, which is about 6/10s of an acre.
