All,
Thank you for your PCN, dated 4/18/2023, for the above referenced project. I have reviewed the information and need
clarification before proceeding with verifying the use of Nationwide Permit (NWP) 29 (https://saw-
reg.usace.army.mil/NWP2021/NWP29.pdf). Please submit the requested information below (via e-mail is fine) within 30
days of receipt of this Notification, otherwise we may deny verification of the use of the Nationwide Permit or consider
your application withdrawn and close the file:
1) The two adjoining parcels on the west and northwest sides, both includes in the PJD review area and owned by
the Applicant, indicate "Future Development", although Section C.6.a of the PCN states that this is not a phased
project. Please provide additional information to enable evaluation as to whether these future development
plans would be considered part of the same single and complete project (see NWP General Condition 15) as the
residential project currently shown. If so, reasonably foreseeable additional impacts to potential waters of the
US would be considered cumulative with impacts for all phases of the single and complete project with respect
to compensatory mitigation and Nationwide Permit (NWP) thresholds. No current plans have been made for
future development or additional phases. If additional phases are planned at a later date, the applicant
acknowledges that additional impacts, should they be required, would be cumulative to the current proposal.
2) The stream crossing as designed appears to re -align approximately 10 linear feet of stream channel between the
downstream headwall and where the flow out of the culvert would intercept the existing natural channel. Note
that this footprint of stream would also be considered a permanent loss and count towards the compensatory

mitigation threshold. The impact drawings and stream impact table have been revised to include the portion of
channel that was realigned. The impacts remain less than the compensatory mitigation threshold. See
attached.
3) Further, the greater than 5-foot vertical drop in the existing stream channel within the proposed rip rap pad
footprint indicates that the stream bed in this location is composed of rock, therefore making the embedding of
rip rap essentially impractical. Recent project experience has shown this to be true (see the attached figure).
Please confirm whether a rip rap pad is required in this location, given that such rock would be
difficult/destructive to embed, and that rock placed on the surface of bedrock would likely cause the stream to
flow under the rip rap, which would be considered a permanent loss of aquatic function and count towards the
compensatory mitigation threshold. The streambed is not composed of bedrock. The elevations shown
represented the elevations beyond the streambed. The culvert cross section has been revised to include
streambed elevations. Additionally, the culvert and associated riprap dissipater have been reconfigured to
match existing streambed elevations at the culvert inlet and outlet. To match up and down gradient elevations,
the culvert slope was increased. Based on the resulting % slope, the culvert will no longer be buried beneath the
streambed. The culvert was designed to be in the current location because it is the most logical location to
provide site access/interconnectivity and provides the most favorable approach gradients on both sides of the
crossing. The culvert slope was designed to match the existing streambed elevation and stream gradient. A
crossing further upstream could not be constructed due to engineering constraints and without creating
improper road curvature and additional stream and wetland impacts. Relocation further downstream would
have similar or greater slopes and steeper approaches and require additional impacts. Based on site and
engineering constraints, the proposed crossing and culvert slope was determined to be the only feasible option
to meet the project needs while maintaining aquatic passage.
Please let me know if you have any questions.
Sincerely,
Dave Bailey
