More Space for Parking Than Offices at Boston-Area TOD

Another
city, another would-be transit-oriented development undermined by a
glut of parking. This time it's Newton, Massachusetts, where plans are underway
to build 420,000 square feet of office space, 60,000 square feet of
retail, and 190 units of housing at the Riverside terminus of Boston's
Green Line, the highest-ridership light rail line in the country.

The station already has a sea of 960 parking spots surrounding it, functioning as a park-and-ride. According to member blog Newton Streets and Sidewalks,
the current plan for development calls for tripling that number, to
2,720 spots. When all is said and done, parking will eat up 748,000
square feet of the project, far more than will be used as commercial
space. 

So how will all that parking affect how people get to this
supposedly "transit-oriented" development? Well, we can safely say it
will generate more car traffic, but the developers haven't bothered to
look at whether they should pursue a less car-centric approach. Writes
Nathan Phillips:

In the world of simulation modeling, analysts routinely conductwhat is called a sensitivity analysis. For a variable of interest (sayvehicle trips in a traffic study), modelers tweak the value of anindependent variable (say # of parking spaces) - increasing/decreasingit by some fraction, and evaluate how sensitively the output variable(traffic) responds.

The "Traffic Impact and Access Study" prepared by Vanasse HangenBrustlin, Inc. for the developers of Riverside, has a glaring,fundamental flaw: it does not study the impact of number of parkingspaces on traffic. This should be one of the FIRST things produced by atraffic study for a proposed development.

Without that information, there's no way to know how this
development can maximize transit use and minimize driving trips.
Continues Phillips:

At a minimum, this study should be extended to evaluate how thenumber of daily vehicle trips would change if the number of parkingspaces were decreased by, say 1/3rd or 1/2, or increased by thosefractions.

Going one step further, involving a glimmer of enlightenedthinking about "transit oriented development", the analysis could thenestimate how restricted parking would drive more use of the D line, theCommuter Rail from the western suburbs, and buses...

Riverside neighbors need to understand that parking is the keylever on traffic. This is a far more effective focus than to focus oncomplicated freeway ramps and yet more pavement. More parking does notalleviate the traffic problem; it exacerbates it. The current planallocates the most space to parking (748,000 sq ft), more than theoffice space and retail space combined. For "transit orienteddevelopment" this makes no sense.
