TALLYN’S RIDGE
PURPOSE & BACKGROUND
The BMP for Tallyn’s Ridge are sump catch basins located at specified structures prior to or at the
outlets of the BMP Basins (see construction documents or BMP Location Map). The sump catch
basins are storm structures constructed with a sump which serves as a sediment storage basin that
can be accessed and cleaned out when necessary.
INSPECTION & MAINTENANCE ACTIVITIES
The performance of a sump catch basin is highly dependant on the inspection and maintenance of
the structure. If the structure is not properly maintained, the ability to remove pollutants will
decrease. The BMP owner will need to provide the maintenance for the sediment removal.
The BMP owner agrees to the following monthly inspection program:
1. Remove manhole lid or open pavement grate to expose inside of box structure.
2. Lower a dip stick equipped with a ball valve (Sludge Judge or similar device) into opened
box structure.
3. Measure the depth of sedimentation. The level of sedimentation shall not exceed 12
inches before maintenance.
4. In the event that maintenance is required, call a local vactor company to remove
sediments and other debris with a vacuum truck. Dispose of all waste in accordance
with the City of Carmel and any applicable state, and/or federal requirements.
