<div dir="ltr"><div dir="ltr">In 2004 I surveyed the subdivision regs for curbing requirements in 187 cities and towns in Eastern MA. I know those have changed... but here's what I found back then, text below. <div><br></div><div>(Full report, published 2005, here: <a href="https://www.dainresearch.com/reports">https://www.dainresearch.com/reports</a>)<br><div><br></div><div>**</div><div><br></div><div>Curbs come in a range of materials (bituminous concrete, granite, or pre-cast concrete)
and shapes (vertical, sloped, or rolled). Municipalities often vary the curbing requirements along roads based on the density of settlement and the types of uses along the
roads. Where curbs are required, more than half of the municipalities require granite
curbing in typical subdivisions, slightly fewer require either bituminous or give an
option between bituminous or granite (often at the discretion of the planning board). </div><div><br></div><div>It is standard practice across most municipalities to require granite curbing at intersections and catch basins, so this was not tracked by the study. Requirements for “cape cod
berms”—rolled curbs—are counted as bituminous. Most of the regulations specified a
curb type to be selected when curbing is installed, but this requirement does not by itself
indicate whether curbing is usually required on subdivision roads. A few municipalities
list that pre-cast concrete curbing is required—these were counted as requiring granite,
since pre-cast concrete is more expensive than bituminous concrete. </div><div><br></div><div>Some of the regulations list clear mandates for a given type of curbing, while others
leave more discretion to the planning board. For example, Abington has a clear requirement for granite curbing (Section IV.B.8):“Each and every street proposed to be built shall
be required to have straight-faced granite curbing, (See Exhibit D), on both sides of the
street for its entire length including all radii regardless of grades.” Acton has a requirement
for bituminous curbing, although it gives the Board discretion to require alternate materials under some circumstances (Section 9.5.1):“A continuous, low-profile, modified Cape
Cod berm shall be provided as an integral part of all new streets. The Board may require
alternate curb materials depending on local conditions and the location and purpose of
the curb.” Marblehead lists either bituminous or granite (Section 258-20.F.7.a):
“Bituminous concrete curb (Type 2) or sloped granite edge per MDPW standards.” </div><div><br></div><div>According to Rebecca Curran, Marblehead Planner, (6/28/04) granite recently has been
the most commonly used curbing material. Burlington’s regulations (Section 10.5) state
that the planning board prefers granite curbing throughout subdivisions; the second alternative is pre-cast concrete; the third preference is bituminous concrete. <br></div></div><div><br></div><div>**</div><div><br></div><div>Amy Dain</div><div>Consultant in Research and Writing</div><div>Dain Research</div><div>Newton, MA </div><div><a href="http://dainresearch.com">dainresearch.com</a></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Nov 28, 2021 at 4:41 PM Jeffrey Robert Levine via MassPlanners <<a href="mailto:massplanners@masscptc.org">massplanners@masscptc.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

I find that most (if not all) New England communities use granite as the baseline. I’ve seen some asphalt allowed but it doesn’t last. Every place I’ve worked around here has had granite curbing as part of their roadway standards.
<div><br>
</div>
<div>In the Midwest, my experience was they used concrete curbing. I think that’s because granite is harder to get there (same reason the farmland there is better, you don’t find rock potatoes everywhere…) The concrete works fine for winter conditions if installed
correctly, but I’m not sure it’s any cheaper here, and granite lasts longer.</div>
