Scope of Work
Amendment #2
Description:
The City has directed the Consultant to revise the design of the proposed storm drain system to
avoid conflicts with Lakehaven Utility District water mains. Conflicts between the storm drain system
and the existing water mains were confirmed after receipt of pothole data just prior to completion of
�the 100% plan set at the following nine (9) approximate locations. E' e
ie{�i€fe�el�
B 210+80 RT, 12"W
A 338+00 LT, 12"W
A 339+10 LT, 12"W
A 339+20 LT, 12"W
C 400+55 LT, 8" W
A 339+50 LT, 12"W
A 341 +25 LT, 12"W
A 342+30 LT, 8"W
A 343+95 LT, 12"W
In addition the City has directed the Consultant to revise the design of the proposed water quality
vau{t and associated piping east of 19th Ave SW. The purpose of the redesign is to avoid the
relocation of the existing water mains within the location of the proposed vault. The vault is to be
placed against the right of way, centered between the Lakehaven Utility District (LUD) sanitary
sewer line and the City 36" storm sewer line. The required 5 feet of working space outside of the
right of way will thus be provided by the existing sanitary sewer and storm sewer easements. If
there is insufficient clearance of the sanitary sewer in this configuration, then the vault may be
rotated 90 degrees and shifted all or part into the existing drainage easement, with thewest vault
wall abutted against the west drainage easement line. The sanitary sewer easement will provide the
5 feet of working space west of the drainage easement.
Scope:
The Consultant will modify the current storm system design to avoid conflicts with the existing
waterlines. Modifications may include lowering or elevating thestorm drain main line, lowering or
elevating the lateral lines, or a combination of both. In some instances catch basins currently
designed as Type 1 will need to be upsized to a Type 2 structure to accommodate the deeper pipe
runs, upsizing pipe or changing the pipe material may be needed. The following are the anticipated
adjustments to be designed:

curb and tie to the main trunk.

A 343+95 LT, 12" W Adjust mainline profile down. Adjust mainline
profile down upstream to pretreatment MH.
U size catch basin to T e 2.
It is anticipated that the adjustments to the storm drain system will entail revisions to two (2) plan
sheets, two (2) profile sheets, and one (1) detail sheet. The Consultantwill determine the differential
construction costs between the 100% design and the modified design. The Consultant will revise
the 100% construction cost estimate to reflect the added costs cf the revised design.
Consultant shall revise the layout of the water quality vault to allow LUD's existing 12" watermain in
SW 336th Street and 8" lateral water main to the Cascade Ridge Apartments to remain in place. The
vault shall be relocated against the existing right of way line or if necessary, into the City's existing
storm easement for Cascade Ridge Apts. Revised layout will be incorporated into the 100%
construction documents.
Assumptions:
Lakehaven Utility District provided pothole data and valve nut measure down information is accurate
and represents actual field conditions at the specific location measured.
Where necessary, depth of Lakehaven Utility District facilities has been interpolated from the
pothole and measure down data. It is assumed that a straight line interpolation between data points
is correct and best represents the horizontal and vertical location of LUD facilities.
It is assumed that one round of review comments, consolidated comments from LUD and the City
will be incorporated into the design.
The City has determined the City's existing storm easement (both on Cascade Ridge Apartment
parcel) may be utilized for installation and operation and maintenance of the vault and related storm
drainage systems. Above-grade working and access space requirements for the vault have been
waived by the City.
