Revisit all mitigation sites to evaluate long- term success. Check records for deed restrictions Visit ordered restoration sites to evaluate long-term success and compliance Visit “pond” excavation sites to evaluate long-term success Follow up as needed
Limit WRP visits to these, only: Not currently being monitored by consultant Not recently monitored by LGU Limit amount of information collected Size = ok/not Veg = ok/not Hydrology = ok/not Deed restrictions if readily available County records not easily checked
If not accessible from road, air photo only Excavations and ordered restorations, air photo only Letter sent requesting permission to visit Deeds not checked; D&U easements D&U easements considered New Wetland Credit only, not Public Value not PVC Did not re-check MnDOT, DNR or BWSR DNR, DNR, or BWSR banks
Air photo review; property line for reference Check with LGU for missing documents Coordinate site visits Invite LGU/TEP Provide final documentation to LGU Provide summary findings to BWSR
St. Andrews Village, Mahtomedi, RCWD, 1999
138 sites visited 20 by air photo review only Inaccessible, no landowner permission
WRP sites not built = 3 One became compliant quickly Two still in process Two questioned, still being reviewed Vegetation quality generally low Exceptions were noted, (8 sedge communities) In early years open water, drier after 2000 Performance standards usually not met
Before, Oct 2010 During, Nov Rapid compliance after notification of enforcement alternatives, Denmark Twp, 2010
Monitoring reports Mostly none, some had 1 or 2 A few consultants had majority of reports submitted Buffer compliance Better in associations Correlation with landowner desires State Farm, 1995, Woodbury Oakdale Trails, 2006, VBWD
Birdfeeder station, within reed canarygrass Fence along pond, buffer at wetland Oakwood Lustre Tnhm, 2007, VBWD
Brookview Terrace, 1999, Woodbury Settlers Glen, 2000, Stillwater Strong correlation between existing vegetation on site and resulting vegetation in new wetland.
Mowing as weed control SMP wetland creation, 1998 Crossroads Commercial, 2005, Woodbury
As-built surveys to verify construction Year 1 report most important
Monitoring reports aren’t being done. Too costly? Too much detail required? Contract management? Vegetation standards may be unreasonable Invasive species management is unsustainable Keep promises realistic Hanson, 1997, Hugo 138 projects x (?/report) = lost revenue
DoR/Easements need better tracking GIS database? Mann Lake Estates, 1996, RCWD Later excavated by landowner into pond
Process has gotten better over time More equitable replacement being proposed Larger developments have better records than small projects Reasonable quality expectations Consider vegetation quality of impacted area Dealt with during sequencing Regarding no-net-loss in Washington County- much more wetland created than shortfall from individual projects Wildlife restorations Non-completed bank projects
