Scoping Sheet and attached Stormwater Management
System Study , .
PW Notes:
1. Show more information on ROW width along South 5th Street for the variable width
portion of the frontage. Show that the existing house is meeting required
setbacks. Show the location of the buildings that are adjacent to the existing
house along 57th St to the north. Show the easement Or ROW dedication in place
across the two properties to the south required to construct the storm drain and
sewer lines.
2. Show existing trees and vegetation on the property
3. Show and dimension private utility easement for Flag Lots 7 & 8. Show, label and
, dimension private sewer easement along the east side of lot 1 & 2. Show and
dimension easement/ROW for utilities across adjacent lots to the south.v
4. Show building envelopes for the residential lots and show any proposed cut and fill
. slopes for the road construction.
5. Show Telephone, Gas and Cable TV line lociltions that will serve this subdivision.
, Show or label the connection point for the proposed water line that will serve this
subdivision.
,6. Show approximate locations of drywells/rain gardens in relation ,to building envelopes
for each lot.
7. Add drainage arrows depecting flow locations and total impervious area.
8. Label all stormwater facilities such as catch basins, lines and discharge locations.
Indicate stormwater travel directions.
9. Show amount of cut/fill anticipated for roadways.
Additional comments not related to the completeness of the application:
. The percolation test from the property to the north may be acceptable if the engineer
that sealed that study is willing to also approve its use for this property.
. Provide a cross section and plan view showing the portion of jon's lane that will be
constructed as part of this development. Also show all easements associated
with the construction and operation of Jon's Lane.
. The Site Assessment plan and Tentative Land Division both show a wastewater
connection from the existing home fronting 57th St to the existing sewer in 57th
St. It is unclear if the property currently has a stub out to the back of sidewalk
or if one is proposed to be constructed. In addition, the sewer manhole that is
shown where the connection from the existing' home intercepts the sewer line
cannot be located in the field. This street is currently under county jurisdiction
and will require their approval for any work to be done in it. In addition this
street appears to be of recent construction and is in good repair. It is unlikely
that a permit will be granted to allow construction within the street that will
disrupt the existing surface. -
. The site currently has two driveways onto .57th st that serve the property. One of
these will need to be demolished and vertical curb and gutter put in place of the
driveway ramp.
