Hi Kyle and Ryan...
am cc'ing Jean Enright and Janet Bernardo on this email to keep them in the loop.
have more thoroughly reviewed the NOI application and plans and in addition to my first two comments about FEMA
maps and Riverfront, I've included some additional notes below:
1. The submittal has the current FEMA maps as opposed to the Preliminary maps- Preliminary should be used
2. 1 was expecting to see the limit of the 200' Riverfront Area project into the baseball field... Can you please check
with LEC about that- how close was the MHW to the baseball field/did they delineate MHW along that stretch ?
3. Are the final results of the test boring available to share?
4. Per the test pit data, there is a dense layer of glacial till - I am wondering if water infiltrating through the new
synthetic turf field and associated panel drains will sheet along the top of that glacial till layer-will the new field
result in water behaving differently over the till and if so what would that look like, any resulting conditions or
impacts to be anticipated?
5. 1 noticed in the Geotech report that they cited Mass DEP infiltration rates- how do these compare to the test pit
rates observed?
6. TSS removal worksheet lists the infiltration basin, and a drainage channel - is the infiltration basin the existing
subsurface basin, and I don't seem to see any drainage channels proposed (can you point them out?)
7. O&M notes "preventative maintenance"of the turf field -what exactly does this entail?
8. O&M of manholes &clean outs- is this done by a vac truck for both?
9. Does the new field impact snow storage/management operations?
10. How exactly will the existing subsurface infiltration basin be protected during construction
11. Do you anticipate any interaction with this subsurface basin during construction of the field surface? If so, how
should it be handled?
12. 1 don't see any discussion of dewatering in the submittal -with perched water observed in the test pits, shouldn't
we anticipate the need to manage water during excavation? Please provide some narrative and plan details for
that.
13. Baseball field construction entrance is not shown as 50'on the Demo&EC plan, as shown on the detail sheet
14. Plan needs to show EC at all light pole locations within jurisdiction at Walsh
15. Wetland restoration area needs to show EC along pavement removal and on either side of restoration work
16. There is a note on the tennis court Demo&EC plan that says"remove and dispose of 15"of soil below proposed
finish grades throughout the replication area" can you explain the purpose of this- is the 15" unsuitable eroded
material?
17. Plant schedule on L101 does not list the quantity of proposed plants
18. Does it make sense to show the construction entrance for the tennis courts? It seems obvious where it should
be installed
19. While on site last week, we observed tons of tennis balls in the wetland, the applicant can anticipate being
required to remove them and policing for this moving forward
20. The track plans should label the event area that is being re-worked (needs a name)
21. The track event area EC should connect with the stockpile area EC
22. Do you have any idea as to the most appropriate location for a construction entrance at the track event area?
Sorry if these seem nit picky, but I figured I'd get them on your radar. And of course, the Conservation Commission may
have a bunch of questions as well.
Thanks for your time. - Amy
