Title, Resolve
Ratifying City Manager's Action for Signing and Submitting a Grant Application to the Maine Department of
Environmental Protection for a Culvert Upgrade on Grandview Avenue
This resolve will ratify the City Manager's submission of a grant application to the Maine Department
of Environmental Protection (DEP) for culvert work on Grandview Avenue. The Maine Department of
Environmental Protection (DEP) had requests for proposals for an available $5,000,000 in grant
funds for road-stream crossing upgrades that were due by November 16, 2020.
The existing culvert across Arctic Brook on Grandview Avenue is a 54-inch corrugated metal culvert.
The culvert is believed to be around 50 years old, and has deteriorated badly. The culvert is also
perched above the stream grade at the outlet, and undersized for the watershed area it serves.
Arctic Brook, which has been classified as an Urban Impaired Stream by the Maine DEP, has a
watershed management plan that was approved in 2016. This plan identifies this stream crossing as
needing replacement with a larger culvert.
The Engineering Department has drafted plans to replace the culvert with a 103-inch wide by
71-inch tall corrugated metal pipe arch at an estimated cost of $136,716.66. The grant application
requests 50% ($68,358.33) of this funding, with the other 50% to come from the Stormwater Utility
Fund.

Dear Mr. K4a[|3in2:
The City of Bangor is pleased to provide you with our application for funding improvements to
the existing stream crossing OfArctic Brook atGrandview Avenue. The existing corrugated
metal pipe isshowing signs ofdeterioration due tDits age and isabarrier tOaquatic organisms.
Grandview Avenue isanimportant cross-link between Broadway and Essex St. Users ofthis
road include residents, commuters, customers of businesses in and around the Broadway
Shopping Center, students of Bangor High School, worshippers at 2 churches, visitors and staff
of a nursing home, staff and patients at a pediatric office, as well as students and staff of
Husson University. A planned replacement should disrupt traffic much less than a failure.
Arctic Brook isclassified asanUrban Impaired Stream b«the Maine DEP. The City has 8
watershed -based management plan to improve water quality in Arctic Brook. The plan
recommends that this culvert be replaced with one of the appropriate size with a natural
bottom for this stream to attain Class B water quality standards. The City intends to replace the
existing structure with 3 pipe arch with strearnbed material placed within. This will increase
hydraulic capacity while lessening erosive flows, as well as increase habitat connectivity for
both aquatic and terrestrial animals living inand around the stream corridor.
We hope that you will consider this important project fOrfunding through this grant program.
Should you have any questions concerning our application, please donot hesitate tOcall rneat

12. Using the space below, discuss what impacts would occur if the culvert/crossing were to fail.
For instance, are there critical public services (fire or police station, hospital, school, public works facility) located
on this road that would be cutoff or required to detour?
Grandview Avenue is an important link between Essex St and Broadway. The next closest connections
between these 2 heavily travelled roads are approximately 6,100 feet north at Burleigh Rd. and 2,250 feet
south at Lancaster Ave, which is not designed to be a through way and is not capable of handling heavy
traffic. Motorists would have to travel to Stillwater Ave. about 6,100 feet if they did not "cut through" at
Lancaster Ave.
Bangor High School is accessed at via Hobart St. about 1,000 feet from the Arctic Brook culvert on
Grandview Avenue. Although Hobart St. also connects to Broadway, the Grandview Avenue entrance is
used primarily by vehicles accessing the High School from "in town" and from the north.
Emergency vehicles such as fire and police would need to find alternate routes. The City of Bangor
experiences very heavy traffic flow on Broadway as well as consistent traffic on Essex Street. Grandview
Avenue is an important connector which helps connect to two roads and avoids overburdening either
one.

15. Using the space below, discuss any other safety concerns about the existing culvert/crossing.
The current culvert has several holes where soil is visible through the pipe wall. These will soon be large enough
to allow for major movement of soils, which could cause sinkholes in the roadway. There are also two deformities
in the crown of the pipe near the center of the pipe, which is under the roadway. The pipe has not been
thoroughly inspected all the way through, but the easily accessible sections near the inlet and outlet are in poor
condition. See photos for details of failures. High velocity flows through this undersized pipe may accelerate the
deterioration.

the crossing, we would like to create a crossing that will be beneficial for macroinvertebrates,
amphibians such as salamanders, and reptiles such as native turtles. This crossing would also allow
small mammals to cross the road without putting themselves in danger of being hit by vehicular traffic.

It is believed that the native soil in the area would be difficult to stabilize
within the stream crossing structure because it is a silty soil. We would
have preferred to add a greater depth of stream bed material within the

better habitat continuity may help to improve the recruitment
23. Provide other information about the design or importance of the proposed project that benefits fish
and/or wildlife such as terrestrial passage, stream banks within the structure, stream simulation design,

10. Provide any additional information regarding the efficiency and cost-effectiveness of the project in the
s ace below:
The City has proposed a 50% match to grant funds on this project. We have done this to show our commitment to
replacing this crossing and hope that this will increase our chances of receiving these grant funds.
The City recently hired a contractor that completed the replacement of an 84 -inch culvert in a 60 -hour period over
a weekend with a complete road closure. This caused the least disruption to traffic possible, and also limited
environmental risk by limiting the amount of time that bypass of flows was necessary. This short construction
schedule also gave us the best pricing possible. We would like to implement a similar schedule on this crossing,
but that depends somewhat on the low bidder's schedule.
11. Provide any additional information as to why this project should be funded by a public infrastructure
grant in the space below:
As previously mentioned in this application, this culvert is currently undersized, and is beginning to show signs of
failure. Replacing this crossing with a properly sized culvert will reduce the chances of catastrophic failure. This
will also encourage the movement of aquatic and terrestrial life between the two most natural reaches of this
urban impaired stream. It is also a part of the City's efforts to improve stream conditions through the
implementation of the Watershed Based Management Plan for Arctic Brook prepared by FB Environmental
Associates for the City.
Recent implementation efforts in accordance with the Watershed Management Plan have been numerous. The
City constructed two underdrained soil filters in 2019 on Whisper Drive, just upstream of the culvert. We also
were able to implement stormwater treatment on Broadway as part of a redevelopment project. The City hired a
geomorphologist to performed an in-depth geomorphic assessment on the upstream reach of this stream. Plans
have been drafted and the City plans to construct these geomorphic habitat improvements in 2021.
11
The implementation of Watershed Management Plan for Arctic Brook also includes the recommendation to
replace the Culvert at Grandview Avenue to reduce scour and increase habitat connectivity. See quote from Arctic
Brook Watershed Management Plan:
Grandview Avenue Crossing: The crossing at Grandview Avenue has a perched outlet with a large
tailwater scour pool. High traffic volume on Grandview Avenue and a steep embankment makes this
culvert at risk from erosion and road runoff. This culvert poses a significant barrier for the continuity of
Arctic Brook to fish and other aquatic species from downstream to upstream. This site is an ideal candidate
for a culvert replacement that has a natural stream bottom and is adequately sized for flow conditions
(large tailwater scour pool indicates that it is currently undersized for flow conditions).
We believe the proposed design meets the criteria for the replacement described in the Watershed Management
Plan when considering the constraints of other infrastructure, costs, and available resources.
