Quick Installation
CON/SPAN® units were installed in a day, allowing for a minimal disturbance to the stream area (North Carolina).
Single Cell
The need for regular maintenance due to silting and debris is nearly eliminated with the use of a single cell (Washington).
Time Savings
Spanning the delineated area avoids the need for individual permits and saves time during planning and review (California).
Preservation
In certain watershed areas, special requirements, more stringent than the standard environmental guidelines, are applied to land development to protect the natural conditions. Here, step pools are created to encourage the success of the native fantail darter (Maryland).
