(/Please check scale on plan sheets as it appears that the illustrated scale is incorrect.

ppomattox Drive (minor collector) should be built as a 60-ft ROW and 38-ft Pavement Width per

lease address.
Please see Sheet 1.
lease verify that all requirements per the Gander Mountain Development Agreement have been
addressed with this design.
❑ I spoke with Jane Kee who worked on the original DA and she felt that all the
requirements had been met, is there something specific you are referring to? Please call
to discuss.
Please address the drainage at the rear of all lots of Phase 2 of Horse Haven which back up to this
proposed development. It appears there is proposed grading which will direct the flow of water
toward these back yards. It is our understanding that there is an existing drainage issue with these
lots.
❑ I spoke to the property owners along Horse Haven Lane and I was told that one of the
property owners had brought in a large amount of fill blocking off the natural drainage. I
went back and installed 18" storm drain lines along the back property line with grate
inlets and re-graved the back lots to solve this problem, see Sheet 5 &the Grading Plan.
Please verify the use of structural backfill where any utility is proposed in a structural area (Streets,
etc).
❑ This is a requirement stated in the Cities standard trenching/backfill details for each
utility. I have included an item for this in the engineers estimate that will also be in the
Contract proposal given to the Contractor and all local Contractors should be aware of
s
this requirement. leo every attempt has been made to'i Weep all of the utilities out from
under the sidewalks. I also added a note on the plan and profile sheets.
eleKease provide elevations every 25-ft in all knuckles/cul-de-sacs.
te„VePlease see plans
lease illustrate all existing utilities in profile view where there is a conflict.
❑ Please see plans
1),A!Sheet 1) Per the BCS Design Guideline—Specs, the bore for an 8-in pipe, requires a 16-in casing.
Please revise in all locations.
o Please see plans
heet 2 and Sheet 3) Please use manhole instead of clean out for termination per BCS design
guidelines.
, lease see plans
heat 4) Please verify the separation between the drainage and water infrastructure as the water
main crosses Switch Station Road.
o There is sufficient clearance between the water line and the storm drain line. In sheet 4
e towdown appears to conflict with the waterline but it does not.
. lease remove all HDPE located under pavement. See below:
• In light of the recent discussions on HDPE pipe deflecting out of round, we should require
RCP under public pavement. Where storm sewer is not under pavement, HDPE with
cement stabilized sand as in the structural trench requirements per detail D3-02 is always
utilized is the minimum acceptable. Note that design engineers are to specifically design
and seal the HDPE detail specific to each set of plans and site. In general we require
structural trenching within 5 ft of public back of curbs or under public sidewalks. HDPE is
acceptable under sidewalks and if the pipe is completely behind the curb. Use this guidance
on the interim. We can about this further in our BCS discussions to memorialize it in the
guidelines. -Alan Gibbs, P.E, City Engineer
o The plans have RCP C76 CLIII Gasketed under all street crossings.
o See HDPE trench/backfill detail on Overall Sheet
o A note was added to the sheets referencing COCS standard detail for structural backfill.
Every attempt has been made to keep all utilities out from under the sidewalk.
. Drainage Report: Please provide a summary of the drainage analysis that was performed for
Gander Mountain; specifically verify that the post development flow conditions of this site do not
exceed the assumptions which were made in the Gander Mountain Report.

o See Revised Plat
9. The Preliminary Plat was approved with the condition that sight issues for lots 38 and 39
(now lots 34 & 39) be addressed and that there be backing maneuver areas on the lots.
Note 12 should apply to these lots as well. If you are addressing the site issue with Note 11,
