Operation and Maintenance Program - City owned Infrastructure
Proactive Programs:
Routine Inspections and Cleaning
Stormwater Services utilizes the City of Concord's snow removal zone map to distribute crews
throughout the City to conduct routine catch basin/inlet inspections. The routine inspections occur
quarterly. However, the City also executes this inspection process after large rain events to assure the
proper functioning of the City's infrastructure. These post rain inspections are triggered by the
Stormwater Superintendent, Water Resources Deputy Director, or Water Resources Director with input
from the City's Transportation Department.
These visual inspections assure no ponding in the roadway and inside the drainage boxes. Any
debris on the drain grates is removed and disposed of. If the inspector sees any issues, like standing
water or abnormal discharges, work orders (CityWorks or other) are initiated to further investigate and
remedy the problem.
Additional proactive inspections are completed by the video inspection truck using the
Wastewater department's basic map. When no scheduled or unexpected work is pending, this crew
works through the drainage basins in an organized manner. Again, any issues identified are placed into
CityWorks for follow up.
Street Sweeping
The City operates two full time street sweepers. These sweepers operate by following mapped
routes throughout the City. Currently, these sweepers sweep every curb section of City streets at least
once per month. Some areas of town, generally those with heavy tree canopy, are swept more
frequently. In addition, some State roads are swept by the City in areas that traditionally have heavy
debris that builds up quickly.
The street sweepers return to the Operations Center to dump debris into a dumpster that
allows the material to drain into the sanitary sewer before being hauled to the landfill for proper
disposal.
GIS Data Collection
The Water Resources Department employees two full time GIS analysts that are in the field
constantly collecting GIS data. These employees are trained to identify both routine stormwater issues
as well as emergency items like illicit discharges and spills. When located, these are reported to their
supervisor for proper dispatching to remedy the issue.
Outfall Inspections (Illicit Discharges)
Stormwater Services maintains a map of all know outfalls of reasonable size. The City's illicit
discharge plan provides more detail on inspection reporting and follow up.

Reactive Maintenance Programs:
Customer Service System
The City of Concord offers residents a 24-hour customer service system. While live phone
attendants are available 24 hours a day, the City also offers online customer requests to be submitted
through online forms and apps. These customer requests are entered into the City's customer
management systems (Harris-Northstar) and then automatically create a service request in the Water
Resources CityWorks system. The CityWorks system is used to track request, create work orders, track
the cost of repairs, and determine timing of services to use for benchmarking purposes. Currently, the
City's benchmark for customer reply is 48 hours. In the case of an urgent afterhours issue, Stormwater
Services has an employee on -call that is reachable throughout non -business hours to discuss or respond
to issues.
Maintenance Resources
The Stormwater Services Department has invested heavily in specialized equipment to assist in
the proper maintenance of City owned infrastructure. The department currently operates two sweeper
trucks, a full-size Jet -Vac (with hydro -excavating capabilities), a state of the art camera truck with
remote video capabilities in addition to three maintenance crews (12 FTE) with various equipment
assigned the their crews including full size excavators, mini excavators, skid steers, hydro -seeders, dump
trucks, etc.
