Norristown Council has approved a Health Care Zone for the area around Montgomery Hospital and the Montgomery County Human Services Center. The Montgomery Hospital building will probably be demolished after the new Einstein Medical Center-Montgomery opens in less than a year at the old Wood’s Golf site, on Germantown Pike near Whitehall Road in East Norriton.  The new zoning designation allows a mix of senior citizen housing and various medical, retail and commercial uses.  Doctors’ offices, a medical college and a nursing school are permitted, but new substance abuse centers, detention centers, adult entertainment, tattoo parlors, check-cashing agencies and takeout beer stores are not allowed.  Council members say the new zoning regulations are designed to keep the neighborhood stable.
