Hi Alex,

Thank you for submitting the pre-construction notification (PCN) for the subject project. I have reviewed the project
package and would like to request the following information:
1. The surveys for the threatened dwarf flowered heartleaf (DFH) were conducted on June 23, 2022, June 15, 2023,
December 12, 2023, and January 10, 2024. The USFWS designated survey window is March through May. Please
clarify how the DFH was identified.
2. Please explain why the impacts for this project cannot be further reduced either by reconfiguring the building
pads/roads or by utilizing retaining walls.
3. The PCN language indicates that there will be temporary impacts to streams and wetlands, but no temporary
impacts are listed in the impact tables. Please provide information on the size, reason, and location of the
proposed temporary impacts.
4. Please provide details on how the building pads will be utilized. The Corps cannot authorize fill for potential
development without a designated purpose.

Additionally, the proposal to relocate DFH will be considered an adverse effect to the species which will necessitate
formal consultation with the USFWS and the development of a Biological Assessment (see guidance attached). The
formal consultation process takes 135 days, and it is possible that a re-survey of DFH during the designated survey
window will be required.

Please provide the above information by 2/29 and let me know if you have any questions.

Thanks,
Shannon
