Commission approves suction dredging and shoreline planting plan at 1506 Oak Bridle
Loading...
Summary
Owners of a small roadside pond at 1506 Oak Bridle won a permit to remove accumulated sediment by suction dredging, dewater on site using geotextile tubes and export spoils, and to install extensive native shoreline plantings and a 4‑tree replacement. The commission attached a standard condition requiring a consultant's final compliance report.
The commission unanimously approved an application Jan. 20 to suction‑dredge and restore a quarter‑acre ornamental pond at 1506 Oak Bridle (application filed by Jeffrey and Stephanie Sibyl, agent Tracy Shalifo).
Landscape architect Tracy Shalifo (Tracy Shalifo LLC) and contractor Mark Amler (Pristine Waters) described a plan to remove about 900 cubic yards of wet sediment (approximately 183 cubic yards dried) using diver‑assisted or hydraulic suction dredging, depending on water temperatures and site conditions. Slurry would be pumped to two geotextile dewatering tubes staged on prepared upland pads north of the pond; dried material would be exported off site. The plan calls for reestablishing an average water depth of about 4.7 feet and up to 8 feet at the deepest pocket and adding 4 native replacement trees, roughly 101 shrubs and about 480 perennials to create a planted buffer and improved shoreline habitat.
Contractor Mark Amler said the biggest logistical challenge is finding sufficient dewatering area; he estimated the active dredging could take four to six weeks once upland dewatering pads and access are established, with an additional month or two for dewatering and truck removal of spoil depending on weather. The applicant said they will not reuse spoil on site and will coordinate off‑site disposal with trucking contractors.
Commission staff recommended a standard post‑construction condition requiring the consultant to submit a final report certifying compliance with the approved planting and erosion‑control plan. The commission approved the application with that condition.
Ending: Work may proceed subject to the approved erosion‑control logistics, required dewatering measures, off‑site disposal of spoils and a final consultant certification of completion.
