2.1 Introduction
The Department of Public Works proposes to relocate an approximately 305’ section of piped culvert,
which carries both the Market Street brook and stormwater runoff, in preparation for redevelopment of 256
Pleasant Street by the Valley Community Development Corporation (VCDC). In the mid-1800’s, approximately
7,000’ of Market Street Brook, which drains to the historic Mill River, was piped underground (see Exhibit A).
Part of this piping exists as an arched brick culvert that runs diagonally southeast across 256 Pleasant Street and
under Holyoke Street. Plans by VCDC to redevelop 256 Pleasant Street and build a mixed-use building propose to
situate the building over the existing culvert. In order to secure future access to the culvert for maintenance,
repair and inspection purposes, this project proposes to relocate the culvert outside of the proposed building
footprint.
The proposed reinforced concrete pipe will be slightly larger (72”x72”) than the existing 60“x 68” brick
culvert, and slightly longer - adding approximately 9 feet in length. According to the hydraulic analysis
conducted by Kleinfelder, relocation of this section of culvert will not alter the hydraulic flow of the brook (see
Exhibit B). Also, the project is not located within rare species habitat. As the culvert conveys drainage from
overlying roads and paved areas, it is eligible for review as a limited project (310 CMR 10.53(3)(d)). The resource
area (Land Under Waterbodies) will expand by about 45 square feet and downstream wetland impacts will be
minimized through the implementation of erosion and sedimentation controls, pursuant to Wetlands Protection
Act standards.
2.2 Existing Conditions
This project is proposed on the property of the former Northampton Lumber at 256 Pleasant Street and
a portion of Holyoke Street. The project site is 100% paved, and gently slopes downward from north to south.
Catch basins along Holyoke Street and on 256 Pleasant Street drain to stormwater systems and to the culvert.
The Market Street brook culvert conveys mostly stormwater flows from a developed area of downtown
Northampton (approximately 196 acres). A small portion of the flow in the culvert can be attributed to natural
brook flows in the northern portion of the watershed which drain from a wetland situated off-site and located
east of the intersection of the Norwottuck Rail Trail and Woodmont Road. The brook flows southerly
aboveground for approximately 700’ before it enters a culvert, where it continues underground through
downtown Northampton for approximately 7,000’. The culvert outfall is located southeast of the intersection of
Hockanum Road and Pleasant Street, where it joins a historic section of the Mill River. The project area is located
approximately 800’ north of this outfall.
2.3 Resource Area Descriptions
Land Under Waterbodies
This resource area was identified through visual observations of water levels in the existing culvert (see
Exhibit C).
The other resource area which could be affected by this proposed project includes the historic Mill
River, which is identified as a perennial stream on USGS maps and is located approximately 800 and more feet
downstream of the site.
2.0 Addendum to Notice of Intent
2.4 Rare Species
The project site in not located within an area of rare species habitat (either estimated or priority) and
thus, coordination with the Natural Heritage and Endangered Species Program (NHESP) is not necessary. (See
Exhibit D)
2.5 Project Description
Proposed Activities
The project proposes to install a 6’x6’ reinforced concrete box culvert along the eastern property
boundary of 256 Pleasant Street and across Holyoke Street, and to transfer flow from the old brick culvert to the
new culvert. This process, as planned, would require excavation of the existing culvert’s upstream and
downstream tie-in points, excavation of the new culvert alignment and construction of the new culvert. A
bypass system to direct flow around the construction area is proposed until the flow is relocated to the
completed culvert.
According to a memo from Kleinfelder, the project’s engineering consultant, dated February 21, 2017,
the new culvert will have the same hydraulic capacity as the old brick culvert (see Exhibit B).
The new culvert will be constructed beginning with the downstream end and progress upstream. This
will allow water to continue to flow through the existing culvert until the new culvert is constructed and the
upstream tie-in is ready to be made. The new alignment will require several bends, and the new culvert includes
angled sweeps to facilitate water flow. Temporary geomembrane bulkheads will be constructed at upstream
and downstream tie-in points to allow bypass pumping when these tie-ins are being constructed (see plans
sheet C-3, C-4 and C-5). Once the new culvert and tie-ins are completed, the temporary bulkhead and plugs will
be removed and the old culvert will be abandoned and completely filled with flowable fill.
Alternatives
The alignment of the existing culvert hinders the approved future development of the site. There are no
feasible alternatives to the proposed project which would result in reduced impacts to the resource area. The
project construction and work sequence have been designed to minimize impacts to the resource areas.
Sequence of Construction
The list below describes the highlights of a proposed sequence of construction that was developed by
Kleinfelder for a permitting discussion with the Army Corps of Engineers.
1. Install siltation bags into existing catch basins and erosion controls within the limit of work.
2. Excavate to expose existing culvert around downstream & upstream tie-in points.
3. Install 1st section of box culvert to be installed outside the footprint of the existing brick culvert. Note:
Contractor to preserve existing flow conditions within the existing Culvert until 90% of the proposed Box
Culvert is installed and both upstream and downstream tie-in can be performed in an immediate

2.6 Project Impacts
The resource area affected by the proposed work is land under waterbodies.
Resource Area Temporary Impact (sf) Permanent Impact (sf)
Land Under Waterbodies 2,190+/-390+/-
Land Under Waterbodies
During construction of the upstream and downstream tie-in points, the temporary impact to the resource
area will be approximately 2,160 square feet. The permanent impact to the resource area, after flow is
transferred to the new culvert, will total approximately 460 square feet of additional resource area.
The following narrative describes how the proposed work within Land Under Waterbodies meets the
performance standards listed in 310 CMR 10.53(d).
310 CMR 10.53 (d) (1) The issuing authority may require a reasonable alternative route with fewer adverse
effects:
Alternative routes are not practicable, given the approved, proposed site plan. Adverse effects have been
minimized and mitigated through use of erosion and sedimentation controls, plans for the water to bypass the
construction area and cleaning of the new culvert section prior to introducing flows.
310 CMR 10.53(d)(2) Best available measures shall be used to minimize adverse effects during construction:
Steel sheeting will be installed to provide support of excavation and will limit the extent of excavation. As shown
on Sheet C-11 of the draft design plans, straw wattles and silt fence will be used to contain soil within the work
limits, catch basin inlets will be protected with silt sacks and soil stockpiled on site will be covered with 20-mil
poly. For dewatering during construction, a geotextile dewatering bag and temporary sediment trap will be
employed to contain and manage sediment laden pump discharge water. Finally, the new culvert will be
cleaned of any sediment or debris, prior to accepting new flow.
310 CMR 10.53(d)(3) The surface vegetation and contours of the area shall be substantially restored:
The project area is paved; no surface vegetation currently exists.
310 CMR 10.53(d)(4) All sewer lines shall be constructed to minimize inflow and leakage:
The proposed storm drainage sewer is a 6’x6’ box culvert constructed in sections of precast concrete. The joints
where sections meet will be sealed to prevent inflow. The exiting brick storm drainage sewer to be abandoned
will be completely filled with flowable fill, preventing it from serving as a conduit for water.
2.7 Mitigation Measures
Erosion and Sedimentation Control
Prior to the start of construction, silt sacks will be installed in catch basins and silt fence and straw
wattles will be installed around the perimeter of the construction area. A geotextile dewatering bag and
temporary sediment trap will be used to contain and manage sediment laden pump discharge water. Soil
stockpiled on site will be covered with 20-mil poly. The steel sheeting support of excavation will limit the
extents of excavation and the potential for erosion during installation of the new culvert.

MEMORANDUM
TO:Doug McDonald, Stormwater Manager, City of Northampton
FROM:Joseph Maliawco, PE
DATE :February 21, 2017
SUBJECT: Former Northampton Lumberyard (256 Pleasant St) Drain Relocation
CC:Rob Kenneally, PE (NH), Matt Tremblay, EIT, File
The City of Northampton is proposing to relocate a section of an existing culvert in order
to eliminate conflict between the culvert and a proposed mix use building to be
constructed directly on top of the culvert by the Valley Community Development
Corporation on the former Northampton Lumberyard at 256 Pleasant St. The City
engaged Kleinfelder to design a relocation of the culvert that would eliminate the conflict
and also improve capacity in the system based on future projected flow that has been
taken from a report prepared by CDM Smith dated November of 2011, and titled
“Stormwater and Flood Control System Assessment and Utility Plan Volume II Final
Draft”
This memorandum is provided to describe a summary of design criteria and assumptions
made during this design phase. In addition, the memorandum will describe the multiple
design components and will serve as the basis for the final design. The option discussed
herein; is based on Kleinfelder’s analysis of hydraulic performance which is documented
herein, is a 6-foot by 6-foot RCP box culvert.
Project Background & Understanding
Valley Community Development Corporation is proposing the construction of a mixed use
multi-story building, which includes an affordable housing component, on private property
at 256 Pleasant Street. This is the site of the former Northampton Lumberyard. The City
of Northampton has a large culvert that runs under this property. The existing culvert is a
5-ft. by 6-ft. stone and brick arch culvert with wood plank flooring which was built in 1846.
The building proposed by Valley CDC is situated directly over the existing culvert location.
As a condition of development, the City has required the culvert to be relocated outside
of the footprint for the proposed building. The relocation will also allow continued access
to the culvert by the City for inspection and maintenance. Relocation of the culvert is to
be completed prior to the start of construction of the proposed building.
The culvert relocation will extend from a point on the eastern side of the former
lumberyard property and will proceed along the eastern side of the parcel to Holyoke
Street. The relocation will cross Holyoke Street on a diagonal and re-connect to the
Exhibit B
Page 2
existing culvert at a point west of Holyoke Street where the material and size of the
existing culvert change to 60-inch diameter reinforced concrete pipe. Replacement of the
culvert in Holyoke Street is expected to disrupt the existing drainage in Holyoke Street
which will need to be reconfigured to accommodate the new culvert. It is anticipated that
the 12” DI water main and the existing 4” and 8” gas lines in Holyoke Street will also need
to be adjusted. As a part of the relocation, the discontinued section of the 1846 culvert
will be abandoned in place by capping the ends and filling the structure with flowable fill.
Kleinfelder has prepared 100% design plans for this relocation which are appended to
this memorandum.
Project Description and Location
The purpose of this project is to reroute flow from an existing 60-inch by 68-inch brick
arch culvert (also known as the 5-ft wide by 6-ft high culvert in a previous memo by
Kleinfelder dated March 21, 2016) to the proposed box culvert conveyance system to
enable a future housing development to be constructed on the project site while
maintaining the City of Northampton’s access to the culvert for maintenance and
monitoring. The rerouted section of culvert will require a series of angled box culvert
drainage sections to negotiate the bends in the alignment and minimize the hydraulic
head loss while conveying storm water flow, past the proposed building footprint, and tie
into the existing culvert further downstream. The relocated section of culvert will consist
of approximately 330 linear feet of a 6-foot by 6-foot reinforced concrete box culvert
recommended by Kleinfelder based on the hydraulic calculations herein. The 100%
design plans that have been prepared by Kleinfelder are included in the Figures section
of this memorandum.
The project site is located at 256 Pleasant Street in the Northampton, MA, between Short
Street to the north, Holyoke Street to the south, and an active railroad to the east. The
railroad property is currently understood to be owned by MassDOT and operated by Pan
AM Railways. The proposed project is to be constructed on a property, which is currently
an abandoned lumber yard known as Northampton Lumber Company. The proposed
project entrance is located on Holyoke Street, directly across from Harold’s Garage.
Refer to the Locus map in the figures section of this memorandum.
Existing Conditions
The existing topographic conditions at the project site consist of relatively flat terrain
gently graded north to south from elevation 123 to 119 towards Holyoke Street with a
small northerly portion of the site graded to Short Street. Based on recent field
investigation and confined space entry performed by EST on July 8, 2016, the section of
the existing culvert to be relocated has been confirmed to be 60-inch by 68-inch brick
arch with a wooden plank base culvert coming in from the east of the site which transitions
to a 54-inch by 60-inch a short distance upstream from the existing manhole #3, at
existing manhole #3 the brick culvert transitions to a 48-inch by 60-inch stone box and
then finally transitions to a 60-inch reinforced concrete pipe 30’ downstream of existing
manhole #3, on Harold’s Garage property and flows downstream roughly 800 linear feet
to an outfall to Mill River. According to the study completed by CDM Smith the existing
Page 3
60” x 68” brick culvert, which is planned to be abandoned and makes up nearly all of the
conveyance system to be replaced, flows with a Manning’s Roughness Coefficient of
0.017 and an average slope of 0.00345 ft/ft. The existing culverts capacity was identified
by CDM Smith to be 266.9 cubic feet per second (cfs). Refer to the figures section for
the design plans to view the existing culvert alignment.
Proposed Conditions
As mentioned, the proposed option is based on maintaining hydraulic consistency
between the existing brick arch culvert and the proposed design. The proposed 6’ x 6’
box culvert alignment includes angled sections of the box culvert in order to create smaller
hydraulic head loss than having the flow turning abruptly at a manhole (refer to the design
plans herein).
At the upstream end of the existing culvert, which is located on the northeast side of the
site, the proposed pipe alignment will tie into the existing 60-inch by 68-inch brick culvert
with a proposed concrete collar to anchor the proposed box culvert section and the
existing brick culvert sections together. The proposed upstream tie-in location will be
located approximately 80 linear feet upstream (north) of an existing catch basin in the 60-
inch by 68-inch brick culvert. Storm water flow from the future development site will be
tied-in to the proposed box culvert via reinforced concrete piping and a drop manhole. It
is assumed the future stormwater flow will be consistent with the existing conditions flows
as determined by CDM Smith. From the upstream tie in location, the alignment will make
an approximate 30 degree bend (to be comprised of two 15° angled sections of the
precast box culvert) to the south east and will continue for approximately 190 LF before
coming to a series of 16° bends. The first set of four 16° bends shall navigate an
approximate total angle of 64° turning back to the south west. The proposed pipe
alignment will then travel approximately 80 linear feet across Holyoke Street. In this
stretch of the proposed alignment the proposed culvert, will be crossing an existing 4”
and 8” gas lines and a 12” ductile iron water main. After crossing Holyoke Street the
proposed alignment will tie into the existing 60-inch reinforced concrete pipe through a
second set of four 16° angled box culvert sections to the 60” reinforced concrete pipe.
This downstream tie-in location is approximately 40 feet south off of Holyoke Street, just
on the back edge of the right of way belonging to the City of Northampton.
Due to the culvert relocation as well as the future development, there is additional
drainage work both within the site and within Holyoke Street that will be required prior to
the construction of the future mixed use building. Sheet C-6 shows the proposed catch
basins, manholes, drop manholes, and piping which collect drainage from the existing
and future VCDC site footprints and tie it into the proposed 6’ x 6’ box culvert. At the
northern tie-in location, both of the existing catch basins (P-CB2, P-CB3) will be re-aligned
with the proposed drain piping and will meet at P-MH8. P-MH8 is located so that it can
accommodate PVC drain lines from the existing catch basins and the future piping coming
from the west. This flow is then routed to P-MH5, in order to stay outside of the future
mixed use building footprint, and then onto P-MH6 (Drop Manhole #2) where it will then
tie into the box culvert via a 12” reinforced concrete pipe. The drainage improvements at
the southern tie-in location consist of 3 manholes and 2 catch basins. P-MH2 replaces a
Page 4
catch basin that was part of the existing brick culvert drainage system, and receives the
existing flow from the drain lines that connected to it. P-MH3 receives flow from P-CB4
(which replaced the old catch basin in the same location) and P-CB1 (which was relocated
due to the box culvert alignment) to the East, P-MH2 to the North, and the extended 24”
reinforced concrete pipe that comes from Pleasant Street (held at existing slope). The
flows from P-MH2 and P-MH1 are dropped down to meet the flow from the extended 24”
and are tied into the box culvert via a proposed 24” reinforced concrete pipe.
Design Objectives and Methodologies
The main objective of this hydraulic analysis is to evaluate the hydraulic response of the
proposed box culvert under the proposed new alignment, as compared to the existing
conditions flows through the 60-inch by 68-inch brick culvert. The proposed pipe
alignment was created by Kleinfelder using the AutoCAD file prepared by Heritage
Survey, Inc. (Southampton, MA) dated February 17, 2014, along with the Market St Storm
Sewer document provided by the town of Northampton dated 1941.
See Attachments at the back of this memorandum for the hydraulic model documentation
for the existing (baseline) condition and the proposed conditions. The intent of the
analysis is to determine if either one or both options will mimic the hydraulic conditions
under the existing conditions flows.
Design Storm Flows
The hydraulic analysis was based on design storm flows for the 2-year storm event, 10-
year storm event, and future peak discharge flow rates. These design storm flows were
obtained from CDM Smith’s (Nov. 2011) report. Presented below are the peak discharge
flow rates for the three design storm events were utilized in this analysis.

(Frequency)

(cfs)

10 year 199.2
Future Peak 206.1
Hydraulic Design Method
The hydraulic analysis was performed using the computer software program SewerGEMS
(version V8i) by Bentley. The drainage culvert was analyzed under peak discharge flow
rates only. The conveyance system headloss was analyzed using the Darcy-Weisbach
Method. The American Association of State Highway and Transportation Officials
(AASHTO) Method was used in the calculation of headloss through the drainage
structures. The AASHTO Method accounted for headloss associated to bends, shaping
adjustment, and non-piped flow adjustment to determine total headloss through the
Page 5
drainage structure. Headloss from expansion and contraction was calculated at the
transition locations in both the existing culvert and proposed culvert. The calculations are
shown in the Headloss Curves in the Figures Section. It should be noted that the
manhole/access points to existing culvert are not constructed as true manholes.
Essentially the existing manhole/access points are comprised of a riser (i.e. chimney)
through the middle of the arched culvert. Therefore, there is no expansion/contraction
headloss in these manhole/access points. The extent of this hydraulic analysis is
intended to be limited to only the proposed conveyance system. However, in an effort to
get a general understanding of hydraulic impacts to upgradient and downgradient section
of the conveyance system, the boundaries of this analysis were extended beyond the
proposed conveyance system. The upgradient hydraulic boundary is limited to a distance
of 80-ft upgradient of the proposed upstream (northern) tie-in location. This location is
shown on the base plan as a bend in the existing conveyance line. The downgradient
boundary condition extends from the southern proposed drainage tie-in, which is the tie-
in point back into the existing 60” RCP conveyance system, and extends down to the
existing outfall. The existing outfall discharges approximately 800 feet downgradient of
the southern tie-in location. The outfall was set with a tail water condition at Elevation
103.9, which is equal to the pipe spring line. In addition, this hydraulic analysis assumes
no additional flow is entering the existing conveyance system downgradient of the
southern tie-in location. Further analysis would be required beyond this evaluation to
determine the impacts of the assumptions listed above.
Hydraulic Analysis Summary of Results
The hydraulic analysis on the existing conditions and the proposed conditions are
summarized in the Attachments A and B as well as the Conduit, Manhole, Transition, and
Outfall Tables. The existing conditions are labeled in order from upstream to
downstream, E1 (Bend upstream from the north tie-in location through E15 (the outfall to
Mill River). The proposed sections start part of the way through E2 (60” x 68” Brick
Culvert) and ties back in at E10 (60” RCP). See attached Hydraulic Model Layout. The
existing brick culvert experiences a maximum hydraulic grade line of 112.35’ at the
upstream bend during the 2-year storm, while under the proposed conditions the hydraulic
grade line for the same storm is 112.37’. The existing brick culvert experiences a
maximum hydraulic grade line of 118.5’ at the upstream bend during the 10-year storm,
while under the proposed conditions the hydraulic grade line for the same storm is
115.92’. The existing brick culvert experiences a maximum hydraulic grade line of
118.86’ at the upstream bend during the Future Peak Storm event, while under the
proposed conditions the hydraulic grade line for the same storm is 116.33’. From the
model output listed above, the proposed 6’ x 6’ box culvert alignment out performs the
existing brick culvert in the 10yr and the future peak storm events while being equivalent
in the 2yr storm. It should be noted that both the existing and proposed conditions
experience a surcharge (pressurized flow) in both the 10-year and Future Peak storm
events.
