Thank you for the link to the latest presentation. The presentation is great at breaking down "how can we get quality out of developers, let's show them the way". Good stuff. The sketches do begin to indicate a commuter rail platform upgrade but I'm still surprised the station does not appear to be central to the presentation. Development is growing around transit centric areas so I thought there would be more focus of a station upgrade to improve the pedestrian relationship to the village, as in larger apartment buildings near the station, more activity in the squares and court yards with commuters walking to and from the station, activating store fronts along the way, etc.
Developing a building on Washington Street that extends over the tracks would provide shelter from the elements, allow for better lighting and allow for elevator service from the street level. I indicated this potential development in the red footprint on the small parking lot off Washington St. and it works with as a landmark "bookend" to the village before crossing the Turnpike.
I still believe the Turnpike ramps, as big and expansive as they may seem, work well. The last thing you want is to make these ramps shorter and have traffic waiting for you at the top of a ramp. Have you driven up the Watertown exit, 55 mph up to a stop sign? Or queuing in traffic on the exit lane while cars go by at 55 mph? I think the ramps could be seen as properly designed for queuing traffic onto local streets. I hope you consider this factor, but I definitely agree the Turnpike could spend capital on better landscaping around the bowl of the large parking lot. I like your suggested west bound on ramp and I included a possible east bound off ramp exit that dumps into the square.
I read up on the deck over the East Milton, this would be an improvement visually and acoustically, but there is mention of not being able to stay for any significant amount of time in the Milton park due to the amount of car exhaust from the highway. Something to consider. The Ponte Vecchio Bridge -esk
buildings on each side of bridges is great, but developing anything less than 20 floors over the turnpike, the investment math doesn't seem to work.
