Division of Water Resources 7/11/2023 Battleship Meeting Notes Holley Snider
Need specifics in design/construction plan on how to properly remove plant material (including
rhizomes) from the site. -Depth of excavation for constructio,.
Reuse of soil should not occur.
Invasives should be pre-treated onsite before construction.
Detail needed on how scour, instability or other erosive/stabilization issues will be handled (after
construction, not talking about NPDES). Potentially addressed by USACE requirements for elevation
monitoring
Consider some freshwater tolerant species within the wetlands fringe around the stormwater pipe
discharge area that can handle freshwater stormwater flows.
O&M Plan and Biological Monitoring Plan
How will the vegetative planting success of planned restoration efforts be quanitifed?
Consider having a mortality threshold where replanting would be required.
Main Tidal Wetlands BMP "Invasives shall be managed regularly." -need detailed post -construction phrag
management plan. May be addressed by O& M plan provide detail.
Tidal Creek- states sediment accumulation is acceptable unless prevents outflow from stormwater
wetland. Potentially addressed by USACE requirements for elevation monitoring
Post -event Inspections will occur "once every 3 months or within 24 hours of any major storm event".
What is a major storm event? 1 inch of rain? A named hurricane?
A minimum of five (5) to seven (7) years of biological monitoring is recommended. Three (3) years may
