Design guidelines are key support materials for administering the preservation overlay zoning ordinance. Guidelines may also be created and used on a voluntary basis, before local historic districts and design review are in place.
Guidelines are community specific.
Borrow ideas, concepts from other towns, but make sure your guidelines deal with your unique buildings and design needs. Well-illustrated with photos and drawings of both appropriate and inappropriate changes. Clear and concise, and free from jargon. A glossary of terms can be helpful. Develop guidelines with public participation and input.
