The Town voted down the amendments.   Backlash: Some Town residents propose to amend the town’s zoning ordinances to tighten limits on College construction: institutional buildings within 300 feet of a residential district would be limited to 45 feet in height (Warrant Article Eight) and set back at least 30 feet (Article 10); and parking facilities for 20 or more vehicles adjoining residential districts would be set back a sprawl-inducing 75 feet from the Districts (Article Nine).   The Town’s own Planning Board is asking voters to defeat the amendments, as does Provost Scherr in his lelter to the Planning Board.   The reduced limits would prohibit new construction from adopting the siting of such existing buildings as the Memorial Field stands, the College notes in a press release.   The Dartmouth also has a report.   Voting takes place May 13.
