Notes, Sketch, Action Items, etc.:
OFFICE REVIEW: **Recommend looking at this one again**
Credits: MY3 credits were not released (499.392 held in 2018)
Stream: Hogan Creek Reach 1 and 2 repairs in 2019. Scour and erosion along these reaches as well.
-Aggradation on Hogan Creek Reach 1
-Scour behind rootwad structure in bank on Hogan Creek Reach 2
-Trees in channel on UT2
-Riffles not maintaining coarser substrate on 4 cross sections.
-XS-4 pool aggradation
-XS-5 riffle downcutting
Encroachment: Mowing in easement on UT2, and road construction on left buffer —50 LF
Invasives: Two treatments in 2018 (honeysuckle, privet, MF Rose, kudzu) 5.1% of easement
Veg: All plots meet but some low vigor due to invasive vines.
My field notes from May 2018 Site Visit:
Office Notes: Invasives treatment Spring 2018. XS -5 increase cross sectional area and right bank erosion. 9 areas of
erosion on R1 and 3. Repairs scheduled for Nov. 2018. R1 and R2 repaired last year. Credits held until site review.5
year project, 900 LF repair planned for this year. Kudzu is an issue.
Field Notes: repair area 1 at top of project is in two sharp meanders. Lots of bank erosion. EI area. Lots of kudzu in
buffer. Veg is thin on right side near last section of repair before bridge. Several mid channel bars. About 30% needs
repair of EI and R. Some encroachment mowing and moving CE signs. Veg below the bridge is much smaller.P area
looks good. Some kudzu there. I recommend 3 more years monitoring after repairs for veg. Kudzu control. HOLD
Credit this year.
10 June, 2019 Field Notes:
Repair areas look very good. The project has already had multiple over bank events since the repair was completed.
Only two locations were concerning, both near the very upper end of the project where there are two tight bends in the
repair area that have flow directed on repaired banks. We asked for photo points on these locations.
The site also needs an invasive treatment soon, with the main concern being kudzu, especially on the lower portion of
the project.
We agreed to catch up on credit releases (currently year 4), but will hold back the entire last release until Closeout. The
project will have monitoring extended by one year for the stream only, and possibly a second year if there are any
concerns regarding stability of the repaired areas.
