Summary of Request:
The applicant seeks to add 3 structures with a total of 6200+sf to the rear of the existing house.
The three structures would contain 5 new units and garage parking.
Zoning Compliance
SITE
2
New construction over 5,000 square feet as well requires a Major Site Plan Review and Approval
with criteria shown under 350-11.6. Additionally, under the table for URB, the addition of 5 units
triggers site plan.
As a major project, two additional components are necessary to be met. First, the stormwater
standards
Site Plan Review means that the use is allowed, however the Planning Board must ensure through
a majority vote (4 out of 7) that the technical details meet the zoning and the site will function
according to the requirements. Unlike a SPECIAL PERMIT, the Board may not deny a project
under site plan review based on determination about “fit” or “appearance” but may only deny a
project based on specific and detailed reasons why the project does not meet the technical
requirements in zoning.
Less than 1,200 feet to the bike path on ramp from this site.
Issues:
Please see the memo and response to issues I raised with the applicant about the following items.
Tree protection and tree removal/replacement. The arborists’ report seems to have some holes
including recommendations for maintain dead trees, while recommending trees to be removed
though they are not dead or diseased or in the way of construction. I will have more feedback
from the city’s arborist who provides technical support to Planning Office by Wednesday.
SPECIFIC COMMENTS FROM CITY ARBORIST
o 1) There is a 23.5" DBH Sugar maple in the front right hand side of the
property that was not inventoried, is that tree remaining or being removed?
o 2) There is an arborvitae hedge that borders the sidewalk that was not
inventoried, are they remaining or being removed?
o 3) There is a clump of Norway maples in the northwest corner of the
property that were not inventoried, are they remaining or being removed?
o 4) Tree ID #1741 are Lilac's, two maple clumps & a cherry tree. The two
maple clumps are considered in my opinion as two separate trees with
multiple leaders. Each leader needs to be measured individually and then
tallied up to make the total DBH of every clump in order to determine if they
fall under the STO.
o The cherry tree is smaller than 20" DBH so it does not qualify under the
STO.
o 5) Tree ID #1730 is a White willow that in my opinion can be left at this time
if the roots are protected from construction damage. Willows are a great
source for native pollinators.
o 6) Tree ID's #1736 (21"DBH) & 1737 (24"DBH) are both over the 20" DBH
so they fall under the STO and are slated to be removed. They will have to
be mitigated for under the present calculations.
o 7) Tree ID is identified as a Norway maple but I believe it is a sugar maple
just for the record.
3
Sidewalks- 350-11.6
All internal and external sidewalks will be constructed of cement concrete. Sidewalks will be at
least six feet in width in all commercial zoning districts and all industrial zoning districts. In all
residential zoning districts, sidewalks shall be at least five feet in width.
The applicant is asking for a waiver from both the cement concrete for the internal driveway
sidewalk and a reduction in width from 5' to 3'?
The existing apron of the driveway and the portion of the driveway crossing the sidewalk will
likely fail due to heavy construction equipment necessary to construct the project. There should
be a permit condition requiring sidewalk replacement panels for all sections of public sidewalk
that are damaged during construction. Our standard for long term viability of public walks is
cement concrete. Replacement will need to conform to current standards which would be in
panel increments 5' wide, despite the fact that the remaining portion on Jackson Street is
currently bituminous.
NOTE: As the City builds new, replaces, repairs sidewalks the standard is for cement concrete –
exemplified by the recent installation of the 10’ wide multipurpose path along Jackson Street
from Barrett to the Bike Path.
Storm water- The initial filing did not include adequate calculation or data to show that storm
water management would meet the City Standards. Department of Public Works is still
reviewing this component.
Please see 3 letters submitted by residents that are in the online filing.
Staff Recommendation
Approve Approve with Conditions Deny
Sustainable Northampton:
This site is 1,200 feet from the Northampton Bike Path, it is within walking distance of the
elementary school as well as retail shopping. The additional units on this lot meet the goals of
the City to encourage new residential units within neighborhoods where the infrastructure can
support it and where it fits in with the design and layout of the parcel.
Planning Board Approval Criteria:
A. The requested use protects adjoining premises against seriously detrimental uses. If
applicable, this shall include provision for surface water drainage, sound and sight buffers and
preservation of views, light, and air; Additional conditions may be required for the applicant to
meet the stormwater standards. Staff will provide those prior to the meeting. Landscaping along
the boundaries of the properties is proposed to be protected/maintained.
B. The requested use will promote the convenience and safety of vehicular and pedestrian
movement within the site and on adjacent streets. If applicable, this shall include considering the
location of driveway openings in relation to traffic and adjacent streets, the arrangement of
parking and loading spaces, and provisions for persons with disabilities; and:
4
The project, including any concurrent road improvements, will not decrease the level of service
(LOS) of all area City and state roads or intersections affected by the project below the existing
conditions when the project is proposed and shall consider the incremental nature of
development and cumulative impacts on the LOS. The project proponent must demonstrate that
all cumulative and incremental traffic impacts have been mitigated. The applicant is proposing a
payment in lieu of traffic mitigation in accordance with the requirement to address the
anticipated 5 peak hour trips to be generated by this project at a rate of $1,000/per trip to be
made to pedestrian and traffic safety improvements in the vicinity.
Access by nonmotorized means has been addressed with a walkway along the driveway and
with facilities such as bike racks.
C. The site will function harmoniously in relation to other structures and open spaces to the
natural landscape, existing buildings and other community assets in the area as it relates to
landscaping, drainage, sight lines, building orientation, massing, egress, and setbacks. The new
units will be located behind the existing structure thereby maintaining the pattern of setbacks and
units as they exist on the block face.
D. The requested use will not overload, and will mitigate adverse impacts on, the City's
resources, including the effect on the City's water supply and distribution system, sanitary and
storm sewage collection and treatment systems, fire protection, streets and schools. The
construction materials and methods for water lines, sanitary sewers, storm sewers, fire
protection, sidewalks, private roads, and other infrastructure shall be those set forth in the
Northampton Subdivision Regulations[1] (even for projects that are not part of a subdivision)
unless the Planning Board finds that a different standard is more appropriate. Major projects that
do not trigger separate stormwater permitting shall have conditions that stipulate when
inspections shall be completed and submitted to the City. Annual reports, as necessary depending
on the stormwater management system, shall be submitted to the City.
E. The requested use meets any special regulations set forth in this chapter. See URB TABLE
for layout standards within the URB zone.
F. Compliance with the following technical performance standards:
(1) Curb cuts onto streets shall be minimized. The existing driveway will continue to be utilized
as the project driveway.
(2) Pedestrian, bicycle and vehicular traffic movement on site must be separated, to the extent
possible, and sidewalks must be provided from public sidewalks. All sidewalks shall meet the
following standards:
(a) All internal and external sidewalks will be constructed of cement concrete (WAIVER IS
REQUESTED). In all residential zoning districts, sidewalks shall be at least five feet in width.
(WAIVER IS REQUESTED)
(c) Ramps allowing access to the sidewalk and street by variously abled persons shall be required
at the corner or within the curb area immediately adjacent to the sidewalk.
(d) For any new driveway, the portion of the driveway that crosses the sidewalk shall conform to
the sidewalk requirements set forth herein, regardless of whether there is a sidewalk
5
improvement extending along the balance of the frontage property, with sidewalks constructed
with extra depth to withstand cars.
(e) The sidewalk cross slope of 1:50 should be maintained across the entire driveway. The
driveway apron should be located in the tree belt between the pedestrian way and the roadway.
(3) Major projects, must be designed so there is no increase in peak flows from the one- or two-
and ten-year Soil Conservation Service design storm from predevelopment conditions (the
condition at the time a site plan approval is requested). Green infrastructure and low-impact
design shall be incorporated to the extent feasible to ensure runoff is handled on site. At the very
minimum, the runoff from up to a one-inch rain storm (first flush) shall be detained on site for an
average of six hours. These requirements shall not apply if the project will discharge into a City
storm drain system that the Planning Board finds can accommodate the expected discharge with
no adverse impacts. In addition, catch basins shall incorporate sumps of a minimum of four feet
and, if they will remain privately owned, a gas trap.
