Additional construction information that is known for the Preferred
Alternative has been included in the Final EIS, including the general
quantities currently estimated for earthwork.
Between Union Street and Bell Street earthwork needed to construct
Elliott Way, the Pine Street extension, and the Overlook Walk would
require approximately 12,000 to 15,000 cubic yards of soil to be removed
and 40,000 to 45,000 cubic yards of fill to be placed. Not included in the
above quantities is the small amount of soil anticipated to be removed
south of Union Street for signal foundations and light poles. Details about
earthwork and concrete work will continue to be developed during final
design with the contractor.

A-002-020
The Final EIS and the corresponding section of Appendix A,
Transportation Discipline Report, have been updated to note that traffic
signals would be provided at intersections on Alaskan Way where
appropriate during construction. During construction, the City may
incorporate parking into areas along Alaskan Way not actively under
construction. Prior to construction, the City would specify the location
and amount of temporary parking that could be put in place, recommend
practices for managing temporary parking, and identify strategies for
making provision of temporary parking convenient and accessible for
waterfront businesses and their patrons.
A-002-021
Viaduct demolition and AWPOW construction will occur within the same
footprint on Columbia Street. As such, close coordination and schedules
will be necessary to ensure construction efficiencies for both projects.
AWPOW’s creation of an interim transit pathway on Columbia Street
would occur only after the Columbia Street ramp demolition is
completed.

The sentence has been revised for clarity. In general, two lanes in each
direction will be open on Alaskan Way during peak periods while Elliott
Way is under construction. Once Elliott Way is completed, two lanes will
generally be open in each direction during peak periods on Alaskan
Way/Elliott Way during the remainder of AWPOW construction. During
off-peak hours, one or more lanes may be closed to facilitate
construction activities.

The pedestrian volumes provided on page 3-10 of the Draft EIS were
obtained from a 2012 City of Seattle technical memorandum entitled
“Piers 54-59 Vehicle and Pedestrian Data.” Data for the technical
memorandum was collected at Piers 54, 55, 56, 57 and 59, and did not
include the area between Madison Street and Yesler Way. The City does
not have any recent pedestrian counts for this area.

Additional text has been added to Final EIS Section 3.2.8, as well as
Section 5.2.8.1 in the Transportation Discipline Report, regarding
pedestrian volumes and annual ferry ridership. Bicycle volumes were not
included in intersection crosswalk volumes, because it was assumed that
a majority of bicycle riders would use the cycle track or the Promenade.

Figure 3-5 in the Draft EIS shows the anticipated 2030 lane configuration
and PM peak hour traffic volumes for the No Action Alternative.
A-002-035
The 2030 No Action Alternative volumes were obtained from EBSP. The
2030 Action Alternative (Draft EIS) volumes incorporated additional data
on ferry forecasts. The Final EIS and Transportation Discipline Report
have been updated so that the vehicle volumes exiting Colman Dock
under the Preferred Alternative are more reflective of 2017 existing
conditions and 2030 No Action Alternative volumes.
The southbound right turn at Yesler Way is assumed to be for WSF staff
accessing Colman Dock. All ferry-bound traffic would enter from the
south (northbound left turn at Yesler Way). The lane colors in Figure 3-8
have been revised as requested.
A-002-036
The proposed configurations of the two access points to Colman Dock,
Yesler Way and Marion Street, take into account that freight, emergency,
and maintenance vehicles will need to enter and exit the ferry facility.
The Yesler Way access is designed to state route standards because
the southern leg of Alaskan Way at that intersection is designated as SR
519. That intersection is designed for both a WB-50 and an SU-30
vehicle to simultaneously enter from, and exit to, the south without
crossing into oncoming traffic. The intersection also accommodates a
single WB-67 turning maneuver from and to the south without the vehicle
crossing into oncoming traffic. The Marion Street intersection is designed
to city standards because both Marion Street and Alaskan Way are city
streets at that location. That intersection is designed for two SU-30
vehicles to exit side by side, allowing one to turn to the north and the
other to turn to the south. The intersection also accommodates a single
exiting WB-62 vehicle turning either to the north or the south.

The City recognizes that loading zone spaces are important in the
Colman Dock area. As shown in Table 3-8 on page 3-35 of the Draft EIS,
there are six existing loading zone spaces on Alaskan Way in Zone 2,
where Colman Dock is located. As shown in Table 3-13 of the Draft EIS,
under the Action Alternative, Zone 2 would gain one loading zone space
for a total of seven. As you know, there is limited space to accommodate
loading zones, taxi zone spaces, parking spaces, and transit stops
between the existing driveways and intersections. Vehicles would
continue to be able to drop off and pick up people traveling to and from
Colman Dock. Walk-on passengers would also continue to be able to
access Colman Dock by walking, bicycling, or taking transit.
A-002-040
Pedestrian volumes crossing Alaskan Way on the north side of Marion
Street and vehicle volumes exiting Colman Dock and turning left on
Alaskan Way were included in the traffic operations analysis. As shown
in Table 7-1 of the Final EIS, the intersection would operate at LOS C
with the Preferred Alternative. Pedestrian volumes are expected to be
Alaskan Way, Promenade, and Overlook Walk Final EIS
Appendix D - Draft EIS Comments and Responses

low at this crossing and therefore would have only a minor impact on
ferry traffic. These relatively low pedestrian volumes are based on the
assumption that the majority of pedestrian traffic from the ferry will use
the Marion Street pedestrian bridge over Alaskan Way on the south side
of the intersection. Also, the number of pedestrians who are accessing
the waterfront for reasons other than ferry travel is low at Marion Street
because it is in the middle of the ferry terminal’s street frontage. It was
assumed that crossings north and south of the ferry terminal would have
higher pedestrian volumes.

New text has been added detailing the WSDOT off-street parking
subsidies to the Final EIS, Section 3.7.2, Operational Impacts of the

Section 7.2.1, Operational Impacts of the Preferred Alternative section.
A-002-042
Colman Dock and the Colman Dock Transit Hub are located in parking
Zone 2, shown in the Final EIS Figure 3-9. All of the 104 parking spaces
lost in Zone 2 under the Preferred Alternative would occur within the
Viaduct footprint (Final EIS Table 3-12). On Alaskan Way, 4 parking
spaces would be added under the Preferred Alternative for a total of 17
parking spaces on Alaskan Way in Zone 2.
While the loss of on-street parking near Colman Dock may contribute to
a reduced capacity for drop-off and pick-up functions for transit riders
within the Colman Dock Transit Hub, Zone 2 would gain one loading
zone space under the Preferred Alternative to have a total of seven
loading zone spaces (Final EIS Table 3-13). Five loading zone spaces
would be located on the west side of Alaskan Way between Columbia
and Marion streets and two loading zone spaces would be located on the
east side of Alaskan Way between Marion and Madison streets. The
loading zones would help to facilitate passenger drop-offs and pick-ups.

Specific estimates of the number of future waterfront visitors shifting from
motorized to transit and nonmotorized modes are not available.
However, according to Commute Seattle, between the years 2012 and
2014, the number of downtown commuters who drove alone declined by
8 percent, while those who took transit and non-motorized modes
increased by 5 percent and 7 percent, respectively. These trends are
expected to continue or increase as improvements to the City’s bicycle,
pedestrian, and transit facilities and services are implemented. Please
refer to Section 2.3.1 of the Final EIS for a detailed description of the
Preferred Alternative’s pedestrian, bicycle, and transit improvements and
the revised Final EIS Appendix A, Transportation Discipline Report. The
results of Commute Seattle’s 2014 Modesplit Survey can be found at:
http://commuteseattle.com/2014-modesplit-survey/. In addition, Sound
Transit has recently seen a large increase in light rail ridership with the
opening of the Capitol Hill and University of Washington stations and
increased frequency of service. A continued increase in transit ridership
is anticipated as their system expands.

Emergency vehicles, such as the Fire Department’s ladder trucks, would
be able to make U-turns at most intersections. A planted median would
prevent vehicles from making U-turns at S. Main, S. Washington, and
Blanchard streets, so emergency vehicles may have to travel one block
further north or south past these intersections to make a U-turn. This text

during periods of heavy rainfall and exacerbates the possibility of an
untreated stormwater-sewage discharge (combined sewer overflow or
CSO) into Elliott Bay. The City of Seattle has entered into a Consent
Decree with EPA and Ecology regarding CSOs, and has developed a
Long-Term Control Plan to support their minimization. AWPOW would
change drainage patterns to divert a portion of the stormwater runoff
area from the combined sewer system to the separated storm drain
system, which would potentially provide a benefit to water quality.

enhanced treatment for discharges to certain fresh waters; however,
Elliott Bay is a marine water, so this requirement does not apply.
