Re: Salters Haven Phase 2
Dear Emily,
The Salters Haven development is currently underway in Hampstead. WLI Investments, LLC
needs to obtain necessary regulatory permitting for minor jurisdictional impacts within Phase
2. In order to record the Phase 2 plat that would allow the sale of those lots, the developer
must obtain bonding which requires that all permitting be in place. LMG understands that we
will be applying for a modification of the Corps GP 291 to authorize the Phase 2 work.
Moving forward with the permitting process is necessary since the developer reports that 175
couples are scheduled to visit the site on April 281h for lot sale reservations .
Recently, you relayed some concerns about possible turbidity noted downstream of the on-
going development and sedimentation issues. On 3/19/20, LMG staff visited the site and
examined conditions throughout the development and downstream. We have attached photos
taken during that visit and location information.
We examined the Grovediere Lane stream crossing and noted elevated turbidity on the
downstream (east) side while the stream water on the upstream (west) side was notably clear
indicating possible erosion or undermining of the culvert pipe itself or some other source of
turbidity to the downstream side. Along Factory Road we noted sediment accumulation from
the eroding swale along the north side of the road moving into the downstream flow. This is a
result of recent powerline work disturbance (not the Salters Haven development), which has
yet to stabilize. We then examined the sediment and erosion control measures taken within the
development and found effective disturbed area containment and remedial actions taken after
substantial rainfall events. We did note some minor maintenance items that we have discussed
with the developer and those items are being addressed.
LMG would like to move forward with the Corps permitting for Phase 2 of the development.
We would like to make our submittal so that the review can proceed in a timely manner.
Please contact us with any questions that you may have and we look forward to your
response. Thank you for your assistance.
