1 SUBJ: Approval of Plans and Specifications
Woodcrest Subdivision, R & R Land Ventures 7-17L_Z__f ---
Project No. 88-9
1 Attached are the construction documents dated "Received June 21 ,
1988" which includes storm sewer and site grading for the six lot
I subdivision located on the south side of Woodhill Road. The City
Council approved the final plat on May 23 , 1988 .
The plans do not indicate any improvements to the existing
1 Woodhill Road. As per condition 12 of the final plat approval,
"The applicant shall negotiate with the City Engineer for curbing
along Lots 3 , 4 and 5 . " At this time, the applicant has not met
I this requirement and shall do so prior to receiving authorization
for grading.
I The grading plan proposes the construction of a sedimentation/
retention pond within Outlot A. This proposed pond maintains the
predeveloped runoff rate while providing more than adequate
4. storage for a 100-year frequency storm event.
IAs per condition 9 of the final plat approval, the storm sewer
pipe should be extended 10 feet beyond the existing watermain
I along Yuma Drive (refer to attachment 1 ) such that repairs could
readily be made to the watermain should the need occur.
I The proposed grading plan calls for the removal of all the trees
within the northern half of the lots. As per condition 1 of the
final plat approval , "There shall be no clear-cutting of the lots
at any time. Grading, erosion control and tree removal plans
I shall be submitted in conjunction with the building permit appli-
cation for Lots 1 through 5 , Block 1. The applicant shall file
proposed deed restrictions upon satisfactory review by City
I staff, the DNR Forester and the City Engineer. The grading shall
be minimized to save trees. " The applicant has agreed to install
a snow fence immediately south of the proposed grading area to
1 prevent unnecessary removal or destruction of trees.

The grading plan shows a detail for erosion control , however , it
does not indicate any location for installation along the lots.
A revised plan indicating the location should be submitted to the
City Engineer for approval prior to the commencement of any
grading.
It is therefore recommended that the plans and specifications r
dated "Received June 21 , 1988" shall be approved subject to the
following conditions:
1. The applicant shall enter into a development contract with the r
City and provide the City with the necessary financial sure-
ties to guarantee proper installation of these public
improvements.
2 . All erosion control measures shall be in place prior to the
commencement of any grading , and once in place shall remain
in place throughout the duration of the construction. The
developer shall be responsible for periodic checks of the ero-
sion controls and shall make all repairs promptly. All ero-
sion controls shall remain intact until an established
vegetative cover has been produced.
3 . Hay bales shall be placed and staked around all storm sewer
inlets.
4. Working hours shall be between the hours of 7: 00 a.m. and 6 : 00
p.m. with no work allowed on Sundays or holidays.
5 . The developer shall be responsible for daily clean-up on and
off the site for debris which has resulted from construction
or construction traffic from the site.
6. Wood-fiber blankets or equivalent shall be used to stablize '
all disturbed slopes greater than 3:1 .
7 . Item 25 , Page EIR-11 of the specification shall be revised to
state: The City will not pay for compaction tests nor re-
testing. This shall remain the contractor 's expense.
8. Item 32 , Page EIR-13 of the specifications shall be revised r
to state: The City will not pay for large trees or bush
replacement . This shall remain the contractor/developer ' s
expense. '
9. Item 20 under special conditions of the specifications shall
be revised to omit Water Department responsibility for
customer notification. This shall be the contractor/ develo-
per ' s responsibility.

mitted for approval by the City Engineer reflecting these
' changes before receiving authorization for grading.

with the recommendations of the soils report .
