Mystic Valley Parkway, Metropolitan Park System of Greater Boston MPS
Why it's listed
Mystic Valley Parkway is a river parkway of just under five miles that follows the Aberjona River, the Mystic Lakes and the Mystic River through Winchester, Medford, Arlington and Somerville, Massachusetts. Planned as part of Boston's metropolitan park system, it was first taken by the Metropolitan Park Commission in 1895, construction began in 1896, and it opened to traffic in September 1897. The road was built 36 feet wide and lit by 66 lights spaced 200 feet apart. Charles Eliot had urged public acquisition of the lake shores to guard against suburban subdivision and pollution. Today the nominated route includes four segments, along with features such as Nelson Circle, the 1936-37 Mystic River Bridge and the Meadow Brook Culvert. A later segment east of Armory Bridge was left out because Interstate 93 construction destroyed its integrity. The parkway is recognized for its roles in landscape architecture, engineering, conservation, recreation and transportation planning.
Significance in brief: The nomination argues the parkway is significant at the state level under Criteria A and C, in architecture, conservation, community planning and development, engineering, entertainment/recreation, landscape architecture and transportation. It fulfills the registration requirements for the river parkway property subtype in the Metropolitan Park System multiple property documentation. It also reflects Charles Eliot's vision of protecting the Mystic Lakes and river banks for public use.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
