Stormwater Maintenance offers annual maintenance contracts tailored to your specific situation and
requirements which usually includes scheduled maintenance services. As in the case of inspections,
our contract can be modified as you prefer. Regardless of who does the specific work, our program
makes sure the facility is being maintained properly.
Our typical maintenance contracts will address the following items:
Mowing
Most maintenance requirements require grass or groundcover be mowed at least two time every year.
Maintain Vegetative Cover
We monitor grass and ground cover and will routinely seed or treat bare areas as needed.
Tree and Brush Removal
Woody growth cannot be allowed to grow on fill embankments or close to riser structures. A proper
mowing schedule will keep trees and brush from becoming established, however, some areas may not be
accessible for mowing equipment. We make sure all areas are maintained to ensure long-term embankment
stability and regulatory compliance.
Trash and Debris Removal
Litter and debris gets washed away in the rain, but guess where it ends up... If removed on a consistent basis, it
shouldn't become a major problem or expense.
Removal of Sediments
Sediments can contain many pollutants and one of the primary purposes of stormwater management is to remove
them before they can reach streams. Maintenance visits allow us to monitor the volume of sediments so we can
clean them out of the facility before they become a major issue.
Risers, Pipes and Other Appertances
These elements are crucial to the function and safety of stormwater management facilities. They regulate
and convey flows from storm events - sometimes at significant volumes and flow rates. The most common problem
that can lead to major problems during large storms is blockage.
Signs of surface external blockage are checked - and corrected - at least twice a year. Underground pipes,
orifices, etc. are inspected for blockage or other problems at least once a year.
Access, Fencing and Safety
We make sure that access and fencing is appropriately maintained. If major repairs or upgrades for safety
should occur, you will know as early as possible to include it in your budgeting process.
We recommend clear signage for all surface facilities to ensure the public is aware of potential danger when
water is impounded during and after storm events. In residential areas, we recommend and can facilitate
public awareness campaigns to make sure the residents, especially children, are aware of potential dangers.
Mosquitoes
Standing water is the perfect habitat for the breeding of mosquitoes. Given the potential of disease and
illness transmitted by these insects, it can be an important issue that those responsible for stormwater management
facilities should be aware of and address. If a problems exists, we approach it using the Integrated Mosquito
Management (IMM) concept. The IMM approach applies consideration of source reduction (reducing standing water,
reducing weed growth, etc.), biological control (fish, bird, and bat habitat establishment), and chemical control
(pesticide application).

Vermin
Rodents, such as groundhogs, beavers, etc. can cause significant damage to stormwater management facilities by burrowing in embankments
or clogging appertances. In most cases, it is the facilities that are not maintained regularly that have the most problems. We survey
for and correct burrow holes and monitor other potentially damaging activity and eradicate the vermin as needed.
