DATE: November 16, 2022
City Engineer Gus Psihoyos is recommending City Council adopt a resolution approving
the proposed plans, specifications, form of contract, and construction estimate in the
amount of $3,203,300 for the Upper Bee Branch Creek Restoration Railroad Sanitary
Interceptor Crossing Project.
The Project consists of the construction of trenchless installation of one 48-inch
diameter steel casing across the railroad property that will house a 36-inch diameter
sanitary sewer, a reinforced concrete transition structure, restoration of Garfield Avenue
(concrete curb and gutter, asphalt pavement, and sidewalk), fiber optic lines, vegetative
surface restoration, and other miscellaneous elements.
I concur with the recommendation and respectfully request Mayor and City Council

INTRODUCTION
The enclosed resolution is in reference to the public hearing for the Upper Bee Branch
Creek Restoration Railroad Sanitary Interceptor Crossing Project (part of Phase IV of the
Bee Branch Watershed Flood Mitigation Project).
BACKGROUND
In November of 2013, the City Council passed Resolution 335-13 adopting the 2013
Drainage Basin Master Plan Amendment. The amended Drainage Basin Master Plan
outlined several improvements throughout the Bee Branch watershed to mitigate the
effects of future flooding and disasters. Collectively, the improvements form the basis of
the Bee Branch Watershed Flood Mitigation Project outlined in Table 1 below.

' Bids for the project were rejected in June of 2022 with the low bid at more than 50% (almost $9 million) over the
engineer's estimate and City budget. Currently exploring re-design/funding options
2 80 of the 240 alleys have been reconstructed as "green", pervious alleys. Several are currently under design.
3 The Upper Bee Branch Creek Restoration Project includes the improvements associated with the Upper Bee
Branch Railroad Culverts Project, including the proposed sanitary sewer crossing through the railroad property.
4 Design complete to Kane Street.
5 Design is complete to Angela St., 60% design to Kirkwood St., 30% design to Rosedale.
Until the sewer system through the railroad property could be installed, a temporary
siphon was installed as part of the Upper Bee Branch Creek Restoration Project
improvements included a temporary siphon to force wastewater flow under the restored
creek, allowing the wastewater to flow west along Garfield Avenue, then south down
Elm Street, and to the Cedar Street Lift Station. Siphons require significant maintenance
challenges and as the flow characteristics necessarily back up wastewater flows which
can lead to the accumulation of solids within the line upstream of the siphon. Installation
of the proposed sewer through the railroad property will allow for the elimination of the
siphon, providing a more hydraulically efficient system that will not be prone to the
accumulation of solids or require frequent, intensive maintenance.
DISCUSSION
Plans and specifications for the Upper Bee Branch Creek Restoration Railroad Sanitary
Interceptor Crossing Project (Project) have been developed and are ready for bidding.
The Project involves the installation of a 36-inch diameter sanitary sewer under the
railroad tracks, providing a connection between the sewer system constructed as part of
the Upper Bee Branch Creek Restoration Project with the sewer system installed with
the Lower Bee Branch Creek Restoration Project. The improvements associated with
the Project were previously designed and bid as an alternate to the Upper Bee Branch
Railroad Culverts Project. With the base bid coming in slightly over the engineering
estimate, the City was not in a position to fund the sanitary sewer improvements at that
time.
Specifically, the Project consists of the construction of trenchless installation of one 48-
inch diameter steel casing across the railroad property that will house a 36-inch
diameter sanitary sewer, a reinforced concrete transition structure, restoration of
Garfield Avenue (concrete curb and gutter, asphalt pavement, and sidewalk), fiber optic
lines, vegetative surface restoration, and other miscellaneous elements.
