Street and Road Layout and Construction.
(a) All projects that include construction of
new or substantial alteration to existing streets and/or roads shall comply
with 974 CMR
2.07 and the construction standards summarized in Table 1:
Street and/or Road Design Standards by
Classification.
(b)
Streets and roads shall be continuous, designed to ensure free movement of
multi-modal traffic and pedestrian flows, and terminate at the exterior
boundary of the project unless the Director determines allowing a lesser
distance is in the public interest. In certain circumstances, the DEC may allow
this requirement to be met by the dedication of a Right-of-way and/or utility
Easement(s) as may be required by MassDevelopment.
(c) Circulation, including vehicular,
pedestrian and bicycle, shall be designed with respect to topography,
integration with surrounding streets and/or roads, connection to existing or
future pedestrian ways, interior circulation and the separation of pedestrians
from vehicles. Bicycle accommodations shall be in accordance with current state
and federal requirements. Neighborhood roads and roads (alleys) will be
designed as shared use facilities where pedestrians and bicyclists have
priority over motor vehicles. Refer to 974 CMR
2.07(3)(b) regarding the design
of neighborhood roads and roads (alleys).
(d) Developments and streets and/or roads
shall facilitate trail Access in accordance with the Devens Main Post Trails
Master Plan and shall follow the Trail Design Guidelines. Applicants shall
provide the DEC with Access Easements over ways and trails that are intended to
be accessible to the public.
(e)
Street and/or road widening, narrowing, or inclusion of traffic calming
measures to assure safety for all users or improve roadway channelization and
controls may be required by the DEC.
(f) Water mains shall connect to the Devens
water supply system and the system shall be designed to form a continuous loop
with existing or proposed water mains. Dead end mains are not
permitted.
(g) Reserve strips
prohibiting Access to streets and/or roads or adjoining property are not
permitted, except where, in the opinion of the DEC, such strips restrict Access
in accordance with the public interest.
(h) Prior to the construction or substantial
modification of street and/or roads, test pits and/or soil borings shall be
performed at locations along the centerline to depths specified by the Director
to determine whether the existing soil can adequately support the street and/or
road. If the soil testing reveals that the soil conditions are not appropriate
to support the proposed street or road, or other structures, the applicant will
be responsible for submitting alternative methods of construction based on
recommendations from a registered structural and/or geotechnical engineer as
appropriate.
(i) Street names shall
be subject to approval by the DEC. Street and/or road signs of the type and
character used within Devens and approved by MassDevelopment Engineering
bearing the name of the street and/or road shall be provided at all
intersections and shall be installed by the Applicant at its cost when the
binder course of the roadway is installed. Safety and traffic control signs
shall be installed by the Applicant in conformance with the Manual on
Uniform Traffic Control Devices (MUTCD), the Massachusetts Department
of Transportation (MassDOT) revisions to MUTCD, and DEC
requirements, as applicable to the specific project location. Historical ovals
of the type and character used within Devens and approved by the DEC shall be
provided and installed by the Applicant at its cost when the binder of the
roadway is installed.
(j) Plans for
Public Ways proposed for public acceptance shall provide for adequate private
long-term Public Way and associated infrastructure maintenance unless and until
the MassDevelopment accepts the Public Ways or agrees to maintain.
(k) Dead-end streets and/or roads or
cul-de-sacs shall only be permitted if the Applicant demonstrates to the
satisfaction of the DEC that connecting to other Devens ways is impractical or
unreasonable. Gated communities are prohibited.
(l) If the DEC allows cul-de-sacs, they shall
have a minimum required outside turning radius of 35'. The centers of the
cul-de-sacs shall be comprised of pervious materials and shall be utilized for
stormwater management (biofiltration landscape island). The Applicant shall
provide pedestrian and bicycle connections to and from the end of the
cul-de-sac.
(2)
Design Standards by Street and Road Classification.
All Design Standards apply to both streets and roads. In accordance with the
Bylaws, all "streets" are Public Ways and "roads" are private ways. Table 1
lists the Design Standards for streets and roads and indicates which
classification is allowed to be public and/or private. In addition to Table 1,
the following additional design standards also apply to the specified roads:
(a)
Road (Alley).
Minimal pavement is to be used in roads (alleys). The travelway shall be no
greater than 18' and shall consist of pervious pavement such as pervious
asphalt, permeable pavers, or a mix of other similar Low Impact Development
(LID) approaches where feasible or any combination of pavement and pervious
materials that increases the infiltration rate in accordance with
974 CMR
4.08:
Stormwater Management.

(b)
Neighborhood Roads. Neighborhood roads are intended to
be less formal than traditional, more highly trafficked streets or roads.
Creativity in developing the design of these facilities is greatly encouraged.
Therefore,
974 CMR
2.00 does not include strict design standards.
Applicants proposing these types of facilities should be familiar with other
Shared Streets facilities that have been designed and constructed and are
strongly encouraged to engage professional Landscape Architects and
Professional Engineers experienced with the design and construction of Shared
Streets
(see Figure 2 for an example of a neighborhood road
layout). Minimal pavement is to be used. Pervious pavement and landscaping
shall be the primary means of infiltrating stormwater runoff generated by the
neighborhood. The Applicant shall be responsible for proposing other means of
handling stormwater runoff in accordance with
974 CMR
4.08:
Stormwater Management.
Click to view
image
Attributes of neighborhood roads include:
1. a ten MPH posted speed;
2. a single travelway;
3. Surfacing with scored concrete, paving
blocks, bricks or other ornamental pavers indicating that the entire surface is
intended for pedestrians as well as vehicles;
4. Recreational or playground facilities if
desired by the developer or required by the DEC.
5. A length limited to serving a maximum of
150 Average Daily Traffic (ADT) from 15 dwelling units.
6. Traffic-calming measures to achieve ten
MPH design speed. The design should limit forward visibility for vehicles to a
maximum of 40'.
7. Traffic calming
techniques should be installed at the entry to the neighborhood road,
indicating to drivers as well as pedestrians and bicyclists that the conditions
along neighborhood road are unusual as compared to traditional street networks
and that caution should be taken when driving in these areas. Traffic calming
techniques may include the following:
a.
Constructing gateways including narrowing the entrance to the shared zone of
the neighborhood road from a standard street or road. Gateways may include the
installation of planters or removable bollards. The gateway design and
installation should not restrict entry to the area by emergency vehicles or
block crosswalks.
b. Consider
raising the entrance to the neighborhood road so that vehicles, bicyclists, and
pedestrians must ascend into the shared area.
c. Post signage indicating speed limits and
instructions to yield to pedestrians.
d. Install different paving materials at the
entrance to and throughout the neighborhood road to indicate to drivers,
bicyclists, and pedestrians that the neighborhood road is not a traditional
street.
e. Introduce chicanes
(serpentine pathways) for vehicular and bicycle travel.
8. Illumination for traffic-calming measures
and any obstacles that may obstruct vehicles or pedestrians;
9. "On-street" parking areas;
10. Landscaping and other Improvements to
facilitate pedestrian movement/activity.
11. Garages serving homes on neighborhood
roads shall use roads (alleys) where feasible. If garage doors open onto a
neighborhood road, the travelway shall provide 28' separation between opposing
garage doors or 24' between a garage door and the far side of the travelway not
abutting a garage door.
(c) For local streets, minor collectors,
major collectors and boulevards, refer to Table 1.
(d) Where a street and/or road standard is
not specified, Applicants may use the following references:

(3)
Traffic Calming
Measures. Traffic calming measures shall be integrated into all
existing and proposed street and/or road designs where feasible to improve
public safety and facilitate Universal Design that results in a safe
multi-modal street and/or road network throughout Devens. Traffic calming
measures include, but are not limited to, the following:
? Street trees every 30'
? Bump-outs/curb extensions
? Pinch points
? Lane offsets/shifts in pavement
? Pavement narrowing (chokers)
? Change in paving materials
? Traffic diverters/barriers
? Speed humps
? Forced turns/intersection islands
? Traffic Circle
? Street and/or road closures
? Raised intersections
? Signalized/raised vrosswalks
? Site furniture/bike racks for intersections adjacent to open
space
The DEC will consider other traffic calming measures on a
case-by-case basis. Refer to MassDOT, Highway Division, Project
Development & Design Guide, 2006 (MHD) for details.
(4)
Street and Road
Edge Standards.
(a) Where curbs
are necessary to protect the roadway edge or to direct drainage, perforated
curbs (that allow runoff to flow into swales) or curbs set flush with pavement
may be considered. Bituminous concrete curbing is not permitted within public
or private Rights-of-ways.
(b)
Where curbs are not necessary, the edge of road shall be protected with a grass
strip flush with the pavement or by other means acceptable to the DEC and
MassDevelopment.
(c) Cement
concrete or vertical granite curbing with a specified reveal shall be installed
in all other areas where LID design techniques have not been
incorporated.
(d) Whenever the
profile or type of curbing material changes, matching transition curb sections
shall be installed.
(e) Guard rails
are required off of the edge of streets/roads with improved/unimproved
shoulders that abut steep slope areas.
(5)
Intersection Design
Standards. While vehicular traffic flow should be carefully
considered, creating safe crossings and accommodating pedestrians, vehicles and
bicycles as much as possible in the Right-of-way takes precedence. Reasonable
reduction of vehicular traffic capacities and level of service at intersections
are justified when high volumes of pedestrians and bicyclists are present.
(a) Streets and/or Road intersections shall
be designed to ensure free movement of Pedestrian, bicycle and vehicular
traffic.
(b) Streets and/or Road
intersections shall align and connect with existing ways at 90° angles to
the maximum extent feasible. Streets and/or roads shall not have intersecting
angles less than 60°.
(c) All
intersection designs shall comply with MassDOT, Highway Division,
Project Development & Design Guide, 2006 (MHD).
(6)
Stormwater
Management.
(a)
Overview. Stormwater Management within subdivisions
generally consists of the control of stormwater runoff within ways. It is
characterized by common, multiple user drainage collected in the ways and
directed towards appropriate receptors. MassDevelopment will usually maintain
or oversee maintenance of these public stormwater management systems.
(b) All Stormwater management systems shall
comply with
974 CMR
4.08:
Stormwater
Management.
(c) The
stormwater management system for the subdivision may be designed and
constructed to include drainage and run-off from developed sites as well as the
roadway. The Director may require the Applicant to provide a stormwater
management plan for the entire subdivision at full build-out to minimize the
total number of detention/retention basins.
(d)
Maintenance of Stormwater
Improvements in Private Ways. Where the DEC requires that road
maintenance be done by the Applicant, the following schedule applies:
1. Biannual inspection of detention/retention
and infiltration facilities for Erosion, debris, sand deposits, and vegetative
growth. Vegetation shall be cut back annually, as appropriate, and debris or
sediment removed from the basins.
2. Submission of an annual report to the DEC
by the Applicant of the detention/ retention basin to the DEC indicating that
maintenance issues have been adequately addressed and that corrective measures
were made where necessary.
(e) Refer to
974 CMR
4.08:
Stormwater Management
for Design Standards and Criteria for Certain Structural Low Impact
Development (LID) Techniques. For combined public/private systems, Applicants
shall obtain authorization from MassDevelopment Engineering and Public Works
for private connections into public systems.
(7)
Landscape Treatment within
Street/Road Rights-of-way
(a)
Purpose. When a new street and/or road is built or
substantially upgraded, the Applicant shall provide street trees and planting
strips.
(b)
Design
Standards.
1. Minimum sizes for
plant material, other than for specific uses indicated elsewhere in
974 CMR
2.00, shall be in accordance with
974 CMR
3.04(8)(c):
General
Provisions.
2. Street
trees are shade trees located along a road and/or street. Applicants shall
plant street trees in accordance with
974 CMR
3.04(8)(k). Multiple species
may be used on the same side of any street between intersections.
3.
Groundplane
Treatment.
a. All unpaved areas
within the Right-of-way (public or private) shall pitch at 1:50
minimum.
b. All unpaved areas
within the Right-of-way with a gradient between 1:50 and 1:3 shall be lawn.
Grass shall be sod, seed, or hydroseed using species mix composition typically
used in New England for grass receiving routine mowing.
c. Any unpaved areas within the Right-of-way
between 1:3 and 1:1.5 shall be planted with low shrubs (under 3' height at
maturity) or groundcover, having fibrous root systems to control
Erosion.
d. Slopes created to meet
existing grades within or immediately adjacent to the Right-of-way shall not be
greater than 1:1.5. Where space is limited or nearby existing trees/woodland
are being retained, the Applicant shall provide retaining walls to avoid slopes
steeper than 1:1.5.
e. Retaining
walls under 4' retaining height shall be mortared fieldstone wall construction
with dry-laid look, brick, or flat face "lock blocks" in a natural stone color
acceptable to the DEC. Retaining walls 4' height or greater shall be concrete
with a fieldstone or brick veneer, or flat face "lock blocks" in a natural
stone color acceptable to the DEC.
f. Within the Rail, Industrial, and Trade
Related District and the Environmental Business District only, the use of trap
rock for bank stabilization may be substituted in the place of the recommended
shrubs. Proposed retaining walls may be concrete.
4.
Shrubs. The
following list of native shrub species is recommended for their high
performance in slope stabilization, urban, and roadside conditions.

Right-of-way.
b. Topographic
alteration and the removal of vegetation beyond the limits of the proposed
Right-of-way shall be kept to the minimum possible extent to meet existing
grades.
c. Vegetation shall be
cleared from the Right-of-way only as needed to accommodate roadway, Utilities,
and sidewalks.
d. Significant trees
(minimum 12" caliper) or woodland vegetation outside the roadbed within the
Right-of-Way shall be preserved by adjusting the alignment of Utilities and
sidewalks to avoid the trees. The Applicant shall provide tree wells for any
grade change of 6" above or below existing finish grade within 6' of the trunk
of a tree to be preserved. Use of dry laid fieldstone construction for tree
wells is encouraged.
e. All work
within the root zone of existing trees to be preserved shall be carried out
under the direction and supervision of a certified arborist.
(8)
Sidewalks.
(a)
Objectives.
1.
Sidewalks are designed primarily for pedestrians.
2. Sidewalks shall become part of a
continuous system.
3. All sidewalks
shall be Americans with Disabilities Act (ADA) compliant, and conform to 521
CMR: Architectural Access Board requirements and shall include
transition intersections with tactile strips at crosswalks.
(b)
Design
Standards.
1. There shall be
three types of sidewalks in Devens: minimum standard, higher standard, and
highest standard. Minimum standard sidewalks are constructed in areas with
lower levels of pedestrian traffic and where appearance is typically of less
importance. These areas include the Rail-related District, the Environmental
Business District, and the Special Use II District. In the Innovation
Technology Business District and the Gateway I and II Districts, minimum
standard sidewalks shall be constructed along minor collector streets/roads,
while higher standard sidewalks shall be constructed in residential districts,
along major collector streets and/or roads. Highest standard sidewalks are used
in areas with relatively high levels of pedestrian traffic.
2. Sidewalk standards are as follows:
a.
Minimum Standard
Sidewalks shall be constructed of bituminous concrete, 5'-0"
minimum width, and shall comply with the dimensions and specifications of the
sidewalk details of
974 CMR
2.00.
b.
Higher Standard Sidewalks shall be constructed using
cement concrete with an SRI of at least 29 and shall be 5'-0" minimum width,
and shall comply with the specifications in
974 CMR
2.00:
Appendix B. Applicants are
encouraged to use pervious concrete. Refer to
974 CMR
4.08(5):
Design
Standards and Criteria for Certain Structural LID Techniques for
pervious concrete construction specifications.
c.
Highest Standard
Sidewalks. Uses that generate particularly high levels of
pedestrian activity, such as schools, transit stops and places of public
assembly shall have cement concrete sidewalks that are the highest standard and
have a 7'-0" minimum width across the entire Lot frontage. The DEC may allow a
lesser width (but in no instance less than 5'-0") or sidewalks along a portion
of the frontage, if the DEC finds adequate pedestrian access and safety will be
provided.
3. Sidewalks
shall run continuously on both sides of all streets and roads to the maximum
extent feasible.
4. Sidewalks shall
be separated from streets and roads by a landscape strip at least 3' wide.
Where Street trees are provided between the sidewalk and street/road, the
landscape strip shall be increased to an appropriate width to ensure survival
of the street trees.
5. Refer to
974 CMR
3.04(6)(a)1.:
Sidewalks/Trails for additional sidewalk
requirements.
(9)
Lighting.
(a)
Design
Standards.
1. All lighting shall
comply with
974 CMR
3.04(6):
Site
Improvements.
2. Light
poles shall be located and spaced to ensure safe and adequate light levels for
all streets and/or roads, intersections and sidewalks. Refer to Table 1 for
maximum spacing and height restrictions for all roads/streets. Fixture height
is measured from the ground to the top of the light fixture/post
assembly.
(b)
Fixture Style.
1.
Within all districts (except the Historic District overlay) fixtures shall
comply with
974 CMR
