Current Projects

Broadway Railroad Culvert

The purpose of this project was to install an 84-inch drainage pipe under the railroad located near Red’s Shoe Barn to rectify long-standing flooding issues. The new drain pipe replaces an old undersized partially blocked granite box culvert installed in the 1800s when the railroad was built. As part of the project, new drain piping was also being installed on Broadway along the frontage of Red’s Shoe Barn and is now connected to the new 84-inch drainage pipe. The new drainage lines will be tied into an existing granite box culvert located in the ravine at the end of Forest Street. Future projects will include installing new drain pipes as part of road reconstruction projects to fix other nearby neighborhoods’ drainage issues. Substantial completion occurred in summer 2021.

Central Avenue North Water Water Improvements

The an aging water main along upper Central Avenue from Abby Sawyer (entrance to Garrison Hill Tower) to Glenwood Avenue was replaced from late summer to early winter 2021. The City Council selected N. Granese & Sons, Inc. as the contractor after a competitive bid process. A compete paving overlay is planned for the spring of 2022.  

City Hall Structural/Safety Improvements

This project is to repair the Municipal Building that was built in 1935. Repairs include replacement of electrical service to the building, installation of a sprinkler system on first and second floors, painting the clock tower and painting trim on building's exterior. 

Cochecho Street Pump Station Replacement

The City is reconstructing the Cocheco Street sewer pump station.  This station currently pumps approximately forty to sixty thousand gallons a day. Final work during the 2021 seasons includes repaving and overlay of a section of Cochecho Street. 

Court Street and Union Street Reconstruction Project

This project would complete a full road reconstruction on Union Street and Court Street from Central Avenue to Middle/Back Road. After a competitive bid process in Spring 2021, a design consultant is working to create engineering plans to allow the City to go out to bid and begin construction, currently targeted for 2022.

Inflow and Infiltration

This project is to reduce the amount of inflow and infiltration (I/I) from stormwater during heavy rain events, which can overwhelm the Wastewater Treatment Plant and disrupt the treatment process. In efforts to reduce I/I, the city contracted to review approximately 125 miles of gravity sewer main within the City of Dover. With the assistance of consultants, flow meters were installed at points in the sewer system to help narrow the locations of high levels of I/I. The meters registered the downtown area with highest amount of I/I, which the City is now taking steps to address. The first project is installing a new sewer pipe underneath the Spaulding Turnpike in the area of Elliot Park on one side and Mill Street on the other. In March 2021, the City Council selected Northeast Earth Mechanics after a competitive bid process to complete the project at a cost not to exceed $742,000. Work began in summer of 2021 and is expected to be complete mid-fall. The next phase of the project includes repairing maintenance holes and other sewer pipes. Work includes removal of roots, mineral build-up and debris, and grouting of cracks and leaking joints. After a competitive bid process, the City Council in June 2021 awarded the bid for the project to Instituform Technologies, LLC. 

Portland Avenue Retaining Wall

The City plans to replace the retaining wall along Portland Avenue near Cochecho Street. In spring 2021, the City solicited a request for proposals (RFP) from qualified firms for design services tasked with evaluating current conditions and develop design engineering plans for the project. In May, after a competitive bid process, the City Council selected Wright-Pierce for designs services at a cost not to exceed $79,900. 

Pudding Hill Water Treatment Plant Construction

The City is working with Underwood Engineers to design water system improvements off Mast Road. Underwood Engineers are currently designing a water treatment plant to treat the water from the City's two wells behind the public works facility. The Planning Board approved the project's site review application in May 2021. The project went out to bid in September 2021. On Nov. 11, 2021, the City Council selected Penta Corporation of Moultonborough to complete the task at its bid price of $13,927,910. Project competition is anticipated in 18 to 24 months.  

River Street Pump Station Upgrades

Community Services is planning upgrades to the sewage pump station at River Street that will include odor control. 

Shaw's Lane Parking Lot Lighting

Community Services installed LED lights in the parking lot for the Shaw's Lane athletic fields.  

Sidewalk Improvements

Each year, Community Services Department establishes a list of sidewalks considered to be a high priority for upgrades. The sidewalks selected for upgrades are designed by the Engineering Division and a construction firm is selected via competitive bid. See the dedicated project page for a list of planned sidewalk upgrades. 

Spur Road Reconstruction

The reconstruction of Spur Road is complete. The contractor returned during 2021 to complete final landscaping touches and apply road paint. Water main improvement/replacement and major roadwork on Spur Road from Finch Lane to Deborah Lane was completed in 2020. Click here for project page. 

Stormwater Asset Management 

The City is working with New Hampshire Department of Environmental Services (DES) through the State Revolving Fund Program to build upon the existing stormwater asset management program.  This project will allow the city to apply condition assessment and prioritization concepts to the city’s subsurface stormwater system located in the most urbanized part of the city. The information gathered will be utilized to identify and fund necessary capital improvement projects.

Street Paving Program

This is an annual program to repave roads as part of Community Services' road surface management program. Click here for streets planned for repaving. Click here for the paving condition index (PCI) for all City streets. 

Traffic Signal Improvements

This project will allow the City of Dover to improve signal timing and traffic flow along Route 108 in the area of Week’s Crossing and through five subsystems of the Central Avenue corridor to Exit 7. The cameras allow for in time adjustments to lights and coordination adjustments during peak times. Furthermore, they allow for real time traffic count information, and automatic incident detection, improving public safety response times.  This project ties in with a concurrent project that Somersworth is proposing, which will improve regional efficiency.

Varney Brook Pump Station

The project upgrades the reliability and energy efficiency of the Varney Brook Pump Station located off Gerrish Road that was built in 1979. The Varney Brook Pump Station is the City’s third largest pump station with a daily flow of 500,000 gallons per day. This project is funded in part by the Clean Water State Revolving Loan Fund. 

Washington Street and Main Street Water Improvements Project 

During 2021, the City of Dover replaced approximately 3,000 feet of 133-year-old water mains on Main Street, Washington Street and a portion of Henry Law Avenue in the Downtown area. The project is necessary to provide reliable water service to the homes and businesses in the project area. A final pavement overlay for the project area is planned for spring of 2022.
