The meeting was held onsite to determine the mitigation ratios for the future permitting of U-2719.
Mapping and impact locations were provided prior to the meeting. The following list details the
mitigation ratios by site.
• SW — 2:1— site was not reviewed but Eric recalls a nice system at the impact location
• ST — 2:1— perennial stream with forested buffer
• SV — ratio not determined in the field — Eric suggested a SAM form be completed to see if impacts
would be at a 1:1 ratio rather than 2:1. Jason shared that he will complete the form and provide
to the USACE. Vickie was to review what the plans were for this channel and get back to everyone
— Update: following SAM Form submittal. Mitigation ratio determined to be a 1:1. The D-8 Team
is evaluating ways to minimize impacts to the stream, park and utilities at this location
• SR — 2:1— Perennial stream at Western Blvd. (old Kmart)
• SO — 2:1— Perennial and looked better than was previously recalled.
• SP — 2:1— Jurisdiction started lower than illustrated on the mapping. Requested HDR look at
options for the driveway to avoid and minimize impacts.
• SN — No mitigation required — had a lot of water in it at the time of visit but was not normal
conditions. Was noted as having no function to require mitigation.
• SE — No mitigation required — appears to carry only stormwater.
• SC — 2:1— House Creek
• SAN — No mitigation required due to existing impacts at the channel tie with SC.
The remaining sites were not field reviewed but it was assumed the mitigation ratio would be 2:1.
Discussion of permitting items needed was had at the end. An EPCN will be completed. A cover letter
was determined unnecessary. A table detailing which pipes will be buried/not buried will be attached.
Reference and attach to the permit application the field review meeting and corresponding minutes to
detail the mitigation ratios.
