This letter is in regard to my inspection of the f nal proposed home site at 311 Victoria Loop.
Since my initial inspection of the property two years ago I have visited the property and the
shoreline below the property six different times as part of your proposal as well as projects in the
vicinity. This letter specifically addresses issues indicated by Michelle Farfan with Jefferson
County Department of Community Development dated July 23, 2007. I visited the.-site with
Michelle Farfan in October and found the proposed development of the site consistent with my
recommendations. Specifically:
1) The 65-foot building setback I recommended has been staked and verified in the field and.
the proposed building on the site is outside the 65-foot setback.
2) Since the original June 20, 2006 report, there have been no changes in shoreline bank
conditions that would lead to a different conclusion regarding the adequacy of the set
back recommendation of 65 feet.
3) I have reviewed the site plan for the location of storm water run off. The plan indicates
that storm water run off from the driveway will be allowed to sheet flow off the driveway
and that footing drains and down spouts will direct water into adispersion/infiltration
trench located on the southern portion of the southwest side of the property.- Due to the
.relatively coarse grained nature of the soils at the site, dispersion and,infiltration of water
at this location will not cause negative impacts to the bluff slope or other properties.
4) Burial or removal of the existing old foundation on the. north portion of the lot will not
cause any slope problems for the slope. Leaving the existing former basement foundation
and concrete garage- slab: will be acceptable and will not cause slope problems.
5) I inspected the proposed home site stakes and determined that the entire home site is
located at least 65 feet back from the tap of the steep slope as measured parallel to the
slope.
I also inspected the existing retaining wall on the southwest side of the property. An email to
Michelle Farfan indicated that wall may be bowing outward due to hydrostatic pressure. I saw no
evidence of the wall bowing outward or being pushed over.
