Thanks Sue. Let me know if this works. I kept the buffer impacts within the LOD and calculated them as if the potential
stream loss went to the LOD. The culvert will not go that far, just enough to get past the pier support. Since they are
planning rip rap bank protection downstream of the culvert extension that may go to the LOD, I just included it all. The
area will continue to be maintained as tall grasses. Pdf pg 6. Thank you.

Good morning Sue. Thanks. Zone 1 buffer impacts 585.1 sqft. No impacts to Zone 2. I'm over estimating too make sure.
Please see pdf page 6 of the updated figures. Please, let me know if you need anything else. Thank you.

Good morning Jason,
I was reviewing this permit modification request and realized that we didn't discuss buffer impacts. The original impacts
were all covered under "existing uses" because they were temporary vegetation impacts to within the existing
maintained corridor, however this culvert extension doesn't fit in that same category because technically some buffer is
completely lost. I can authorize this under "protection of existing structures" but I will have to issue a formal buffer
authorization to do so. The maps you sent show the buffer, can you just provide me with a calculation of square feet of
Z1 and Z2 that will be "lost" adjacent to the extended culvert please.
Thanks.

Hi David and Sue. The contractors doing the aerial pipe replacement work at Richland Creek came across a piling for the
48-inch sewer line that is experiencing erosion from the adjacent stream (intermittent stream SL). We would like to
stabilize this piling for the aerial sewer infrastructure. To ensure there will not be future erosion we're proposing a
culvert extension past the piling vs. just fill and rip rap on the stream bank next to the piling. Some figures and plans
with notes are attached. Hoping we can modify the existing approvals for this project to include this work. This area is
currently designated as temporary stream impact S7. I'm not sure the exact length of culvert needed but just enough to
get it past the pier. The extension shown on the attached plans is —12 feet. We would want to add some riprap and filter
fabric to the stream bank at the culvert outlet for protection. The total permanent impacts would potentially go to the
LOD shown and would be a maximum of 23 feet, matching the length of the current temporary impact S7. The proposed
work is within the currently maintained easement. Impact S7 is 0.003 acres. If you would, please let me know how best
to proceed. Thank you.
