Andrea — I understand the concerns about sediment. The stream from the south runs along the eastern shoreline of the
pond to what appears to be the old spillway, and we're expecting it will continue to flow in its channel separate from the
work area in the pond footprint. We're expecting the culvert will be active in draining the groundwater held in the pond
sediments but not really carrying stream flow. It's going to require some field fitting to make it work since it's difficult
to predict exactly how much groundwater will be held in the sediments and how low the culvert will need to be. We
may also need to define a diversion channel along the eastern shore if the bed of the existing channel is higher than the
bottom of the pond sediments.
The planted buffer will likely be as wide as the pond footprint — say at least 50'. This area will be dedicated to the
restored stream.
Feel free to call me if you'd like to discuss this more.
Thanks.

Hi Britten and Andrew -
I've got a couple of questions about the Springs of North Asheville PCN:
• Can you expand on how the pond will be drained? The design notes that a temporary culvert will be
placed 3 ft below the pond bottom elevation, and rock pipe inlet protection will be used to capture
1

sediment. I'm a bit concerned that a pipe set at 3 ft below the pond bottom elevation will end up
pulling a lot of sediment from the pond bottom, and that rock pipe inlet protection won't do the job.
• How wide will the planted buffer be?
Thank you,
Andrea
