Description:
Project #6 is associated with the lack of conveyance in the east -west channel south of the
residential properties on the south side of Majestic Avenue from Laconia Street to the
Stonecrop stormwater best management practice wetland treatment facility. Hydraulic
modeling indicates insufficient capacity in the culvert crossings at Laconia Street, Bevan
Drive and Stonecrop Street. The objective of this project is to replace the road crossings
at Laconia Street, Bevan Drive and Stonecrop Street to provide increased capacity at each
of the road crossings to alleviate flooding. In addition, the modeling indicates insufficient
capacity in the Majestic Channel upon replacement of the existing insufficient road
crossing culverts. It was determined the top -of -ditch width of the Majestic Channel was
equal to the width of the right-of-way. The only alternative to obtain the required
capacity in the channel is to excavate vertical walls and line this portion of the ditch with
sheet walls or other vertical structure from Laconia Street to Stonecrop Street, which
would also be included in this project.
The current conceptual budget estimate for this project is $1,366,000, including design
and construction. This number may change based on final design specifications and
market conditions.
