Restore Cambridge Housing Zoning Petition WHEREAS: Cambridge is a beautiful city with many diverse neighborhoods and people; WHEREAS: Most if not all Cambridge neighborhoods were downzoned decades ago, making many existing buildings non-conforming and illegal to build today; WHEREAS: Housing demand greatly outstrips new construction; WHEREAS: Current zoning in multi-family districts promotes expensive single-family home in- fill, despite numerous adjacent and nearby multi-family homes; WHEREAS: The inability to build homes similar to existing ones is confounding; WHEREAS: Renovating and improving existing buildings is made difficult by current zoning; WHEREAS: Neighborhood character is just as dependent if not more on the residents than the buildings in which they reside; WHEREAS: Restoring the ability to create new homes similar to existing ones improves all aspects of neighborhood character, primarily by the slowing of displacement of residents and accommodating growth; WHEREAS: Concentrating zoning increases along business and transit corridors is beneficial to creating a more sustainable city; WHEREAS: First floor retail with housing above in business districts promotes a lively and walkable city; WHEREAS: The following zoning changes may provide a start to an incremental improvement that the undersigned hope can be swiftly agreed upon by the City Council; THEREFORE WE, THE UNDERSIGNED, ask the Cambridge City Council to consider and pass the attached zoning petition to restore the ability to create and expand Cambridge neighborhoods that are beloved by many.
