History of Stormwater Management
WHY DO THIS TRAINING?• Fairfax County conducts inspections on all privately owned
SWM/BMPs at least once every 5 years (750+/year).• Approximately 69% (3,900 of the 5,600) of SWM/BMP County
facilities are privately owned.– More than 80% of privately owned facilities required maintenance
(noted deficiencies) in the last inspection cycle.– Some owners lack a full understanding of
the maintenance requirements for their SWM/BMPs.
– Understanding the basic requirements & importance of timely maintenance/repairs serves everyone’s interest, supports public safety, & helps facilities function as designed.

WHAT’S NEXT?
Fairfax County will compile a list of all attendees, and this list will be: – Posted on the County’s stormwater website as a public resource– Provided as an attachment with the final inspection report sent to each private
owner– Used to notify attendees of any future County training opportunities
So, let’s get started!Please note the following disclaimer will be on the County Contractor Listing: The companies and/or individuals listed below hold a Certificate of Attendance from the Fairfax County Maintenance and Stormwater Management Division’s Stormwater Maintenance Contractor Training Program.

History of Stormwater Management
A watershed is an area of land which drains into a specific water body (e.g., river, stream, or lake) due to the topography of an area
(i.e., the lay of the land).

History of Stormwater Management
• The County Storm Drainage System is a network of public and private structures, channels, and underground pipes that carries stormwater runoff directly to local receiving waters.– SWM/BMPs are a vital tool in managing this runoff.
• Urbanization increases:– Non-point source pollution in stormwater run-off (a water quality issue)– Downstream flooding (a water quantity issue)

History of Stormwater Management
When SWM/BMP facilities function as designed they help to manage:
• Water quality• Water quantity
– Timing – Distribution
Collection
Conveyance
Management

History of Stormwater Management
• Stormwater Management (SWM, BMP, or both):– SWM facilities provide water quantity management through:
• Reduction of downstream flooding via temporary storage• Quantity control of runoff from impervious areas (e.g., pavement,
sidewalks, etc.)• Aiding control of larger flood events (i.e., 2- and 10-year events)
– BMPs provide water quality management by temporary storage and via:• Settling• Infiltration (slow movement into ground)• Filtration (biological or mechanical separation)• Biological nutrient uptake

MSMD/DPWES
Fairfax County Inspections- Basic OverviewPrivate Inspection Program’s 4 basic steps:
• Step 1– The County notifies the owner in advance of an inspection.– Inspectors prepare appropriate maps/documents (e.g., appropriate County
Inspection form for the SWM/BMP type, easement information, etc.).• Step 2
– Visual condition assessments (inspections) are conducted & facility components documented by photograph.
– Common maintenance items are recorded by relative severity on a field inspection form and any unusual items are noted.

Fairfax County Inspections- Basic Overview• Step 3
– Inspection results are then verified, reviewed, and formatted in the office into a formal report provided to the owner.
– Owner responses are tracked in a County database, with checkpoints at specific dates from when the owner received the
inspection report and follow-up correspondence.• 45-days (deadline for maintenance completion/written response) • 90- & 135-days (responses are delinquent)• A completed/signed Maintenance Activity Report (MAR) MUST be received
to close the inspection file! NOTE: Inspections are only a “point in time” observation of the condition at a SWM/BMP facility.
