Combining Over 80 Years of Local Experience

Spurr Co. and North Coast Engineering have teamed together to provide expertise in the operations and maintenance of state regulated stormwater facilities.

How It Works

CS3 provides stormwater maintenance and Stormwater Board inspection and documentation for all facilities. Annual inspections and cleanings of your stormwater system help prevent costly fines and ensure operation at optimal efficiency.

Sweeping and Cleaning of Pervious Concrete

Pervious surfaces allow runoff from parking areas to percolate through the concrete and into the underlying rock section. The runoff is then treated through infiltration into native soils.

sediment removal of catch basins

Treats stormwater of various pollutants through infiltration of smaller storm events into groundwater. Mitigates peak flows by detaining runoff and metering release of flow through a controlled outlet system

replacement of bio-swale soil mix

A bioswale is a permanet, channel used to direct stormwater to infiltration areas or engineered containment systems.

hydrodynamic separator sediment and trash removal

Separates pollutants like oils, sediment, and debris from stormwater through the use of a spiral design. A sump in the design stores the oils and sediment to be removed when neccessary.

replacement of media filters including roof downspouts

Downspouts divert the water away from the natural flow of a downspout toward the rainwater storage tank.

Settling Basins

For Hydrodynamic Separators a maintenance schedule can be determined by the rate of oil/sediment accrual. Removal of oils, sediment, and trash should be done at least annually with a Vac Truck. Settling basins are often placed upstream. Therefore, if maintenance is not performed, these basins can fail to work because they are clogged with debris and sediment.

Retention/ Detention Basins

For Retention/ Detention Basins, inspections should be conducted biannually, at the beginning and end of the rainy season. Removal of sediment and trash is need to avoid clogging of outlet pipes. Detention basins rely on void space between drain rocks to provide volume for stormwater to be detained. If maintenance is not performed, the more sediment and debris filling in the void space will cause overflow and not have the capacity for a large storm. The basins also rely on infiltration into the groundwater.

Pervious Surfaces

For Pervious Surfaces, each area should be checked following a storm to determine that no water is ponding on the surface. Surfaces should be maintained through sweeping and blowing monthly. If this surface is not maintained, water will pond. If the void spaces within the concrete become blocked, it can lead to erosion in other areas not intended for concentrated runoff. It could become troublesome for people parking their vehicles.
