FROH: John A. Harwood, P.E., OSH , Associates, Inc.
DATE: Karch 26, 1990
SUBJECT: Conditional Use permit, Fill Placement
Lot 2, aloex 5, Boulder Bridge, Case 90.05
I have reviewed the data submitted with the referenced application.
The purpose of the fill is to enhance the aesthetics and usability
of the lot. The placement of fill on this site is appropriate and
can be performed without detrimental impacts to abutting public or
private property.
At this time, a significant amount of fill material has been placed
on the site. The material has not yet been spread or compacted.
The applicant should be requested to provide a revised site grading
plan incorporating or addressing the following three questions. In
addition, due to the nature of the fill material there is potential
for significant problems during material hauling and placement.
Approval should not be granted until problems related to haul and
placement are addressed.
1. The grading plan shows fill placement to and beyond the
property lines on both Smi thtown Road and Boulder Circle.
This places fill in the existing ditch drainage ways for both
roads. A revised grading plan is required showing fill
limited so as to not impact drainage~
The revised site grading plan should show a typical section
for each road, show the edge of pavement, show the width of
shoulder and show the location of existing ditches or a
location for a newly graded ditch. The location of the
proposed fill limits should be dimensioned from the edge of
pavement.
It is noted that the fill operation now underway does not
appear to extend onto the right of way for smithtown Road and
will not impact the Smithtown Road ditch or drainage. The
limits of fill along smithtown Road, that are defined by the
hay bales now in place as erosion control, 'would be
appropriate. The existing ditch along BOUlder e~ e.di- is not

/
well defined nor is it deep enough. It is recommended that
the applicant, coincident to the proposed fill placement and
grading operation, improve the existing Boulder circle
drainage by grading a minimum 1.0 feet deep ditch section
located approximately 5 feet easterly of the edge of pavement
or Boulder Circle and match the proposed fill to that ditch
section.
2.
The proposal is to utilize material dredged from the lake
placed as fill, with 3: 1 slope. The site plan should b~
revised to show a maximum 4:1 slope. The material is likely
to be a highly erodible organic silt that will not be stable
at a 3:1 angle of repose. The flattened slope is intended to
minimize future possible erosion into roadside ditches.
3.
There is an issue related to maintaining sight distance for
vehicles approaching Smithtown Road from Boulder Circle. It
is believed that the revised plan that limits fill placement
to not encroach on the smithtown Road ditch and incorporates
the 4:1 slopes as described above will provide adequate sight
distance.
There may be a major problem with the hauling and fill operation
for material of this sort unless the material is properly dewatered
prior to Use. The applicant should be requested to submit data on
anticipated "consistency" and water content of the fill material as
it is being transported and placed.
Any review of this proposal as "fill placement" is conditioned on
the material being relatively dry prior to being transported over
city streets or placed on the sites as fill.
For transport, the material should not be "muck". A reasonable
definition for transport purposes would be material having a voids
ratio. not greater than 0.95 (i. e. minimum 5% air voids). For
placement, the material should be relatively dry. For the
anticipated organic silt a moisture content not more than 115% of
optimum would be appropriate. It is noted that the fill material
that is on the site is a black to grey organic silt, likely dredge
material. It appears to have been relatively dry during transport
as evidenced by it being dumped in piles and not as muck and that
the material now on site is very dry.
