5/23/2013 comment -Please provide an itemized engineers cost estimate, including units and
unit prices, for both on-site and off-site (right-of-way) improvements, including all utilities,
traffic control, and restoration/enhancement plantings. Please use the King County Site
Improvement Bond Quantity Worksheet and utilize the “write-in” sections where appropriate.
Abond is required to be placed for all erosion control measures, right-of-way and
stormwater management improvements. Posting a bond for stormwater systems applies to
subdivisions that involve 7,000 square feet or more of land disturbing activity and as well as
on projects in a critical area or buffer including ESLHA. The amount of the bond will be
based on 120% of the City approved estimate. The City will inform you of the appropriate
bond amount after review of the cost estimate. Please obtain the appropriate subdivision
improvement bond forms from the City.
If you intend to post a bond in order to record the subdivision, the bond amount will be
based on the entire scope of the project.
Inspection fees for this project will be calculated at 2.2% of the120% City approved
estimate for all improvements.
2.August 20, 2013 –Response letter states the traffic control and haul route plan will be
submitted separately to the City.
5/23/2013 comment -Please submit a traffic control and haul route plan for review and
approval.

4.August 20, 2013 –The response letter from Mr. Tietze references a letter dated November
26, 2012 by Liu & Associates; however, this letter was submitted as part of the preliminary
subdivision application, and certain aspects of the civil plans have changed from then to
now. It was noted that a letter was provided by Liu & Associates dated June 26, 2013
addressing the access road retaining wall. However, since the current civil plans are
different than the original proposal reviewed by Liu & Associates and since the latest
letter by Liu & Associates (June 26, 2013) only addressed the access road retaining wall
and did not address the latest civil plans in their entirety, please provide an addendum by
Liu & Associates reviewing the current civil plans in order to ensure that the proposal is
still in compliance with the applicable critical areas regulations of ECDC 23.40 and 23.80.
5/23/2013 comment -Since much of the site contains a Landslide Hazard Area, this phase of the
project will need to be reviewed by a qualified geotechnical engineer pursuant to ECDC 23.40
and 23.80.Please provide a letter by a qualified geotechnical engineer that addresses how the
proposed work associated with the civil improvements, tree removal, and vegetation
management planis consistent with the critical areas regulations of ECDC 23.40 and 23.80 and
providing any additional recommendations for what would need to be done in order to comply
with the critical areas regulations and avoid any potential negative impacts to the stability of the
slope.

8.August 20, 2013 –The response letter states the slope of the driveway must be kept as
steep as possible in order to keep the house grade up above the hillside to the south. The
driveway slope has been reduced to 19.1%. As noted below, a request for waiver will need
to be processed as a Type II decision and requires noticing. Please refer to ECDC
18.80.060.D and provide a written request for waiver that addresses the stated criteria of
approval. If you can submit the request by August 26, 2013 I can schedule the noticing in
the newspaper, etc.
5/23/2013 comment -The driveway has been designed with a 19.9% slope. City code allows
for a maximum14% slope, with the potential to receive a waiver up to 20% with noticingas a
Type II land use decisionand approval by the Public Works Director. Please refer to ECDC
18.80.060.D and revise plans or respond accordingly.If you choose to proceed with a driveway
slope design of over 14%, please reduce the slope below 20% as much as feasible. A design at
almost 20% leaves no allowance for adjustments during construction.
