2. COMMITTEE BUSINESS
1. Committee Updates
Public Works Feasibility Study for a Police Substation on Hwy 99
Mr. Antillon reported the contract has been awarded and a kick-off meeting held last week. The
contractor has worked with cities in Washington and has a lot of experience. He may reach out to
councilmembers for input. Questions and discussion followed regarding other potential sites such as
the vacant 7-Eleven on Highway 99, getting the police department's input regarding an appropriate site,
collaborating with South County Fire on the Value Village site, parking for police vehicles, timeline for
the feasibility study, and whether renovating the 7-Eleven site could happen sooner than construction
on the Value Village site.
Utility Rate Study
Mr. De Lilla reviewed:
Rate Analysis
o $89,410 contract with FCS Group
■ Rates and GFCs for W/SS/SD
■ Final checks on data. Analysis in progress
■ First submittal to council committee September 2023
■ Final approval Nov/Dec 2023
■ Rates to be effective Jan 2024 (3 years)
o Added to CIP since last analysis
■ Yost and Seaview Reservoir structural rehabs
■ Alderwood WWWD predicts 8%/year increases in water costs for foreseeable future
■ Edmonds WWTP denitrification project (city share-50.8%)
■ Lynnwood WWTP replace (City share-11.54%)
■ Perrinville, Ballinger, SR-104 WQ projects (grants need City match funds)
Questions and discussion followed regarding increases in wholesale water costs, Lynnwood's interest
in annexing land around the Lynnwood WWTP, ownership of the Lynnwood WWTP, Ballinger water
quality project, Mathay Ballinger infiltration project, the City's share of Lynnwood WWTP, whether an
infiltration project could be located on the Interurban Trail, and next steps to slow erosion in Shell Creek.
Committee recommendation: Update only

2. Presentation of Ordinance Amending Section 8.16.040 from Edmonds City Code
(ECC), Amending the Speed Limit along Highway 99 from 244th St. SW to 210th
St. SW.
Mr. Hauss reported the recent conversion of the Highway 99 corridor from an open 7 lane roadway
section to 3 lane sections for northbound and southbound movements separated by the raised center
median two-way will help improve safety. As the corridor is within WSDOT right-of-way, WSDOT
permission is required to reduce the speed limit. WSDOT approved the City's request to reduce the
speed limit on 2.5 miles of Highway 99 from 244th to 2101h from 45 mph to 40 mph. The speed reduction
is consistent with the cross-section and speed limit in Shoreline. The northbound lanes of Highway 99
between 220th and 212th are in Lynnwood; Lynnwood has also approved the speed limit reduction.
Based on an existing maintenance agreement between WSDOT and Edmonds, the City would be
responsible for any traffic sign modifications.
Questions and discussion followed regarding potentially revising coordination of signals, criteria to
reduce the speed limit to 35 mph, whether speed limits could be reduced with the addition of bike lanes,
and potential for Lynnwood to install raised medians on Highway 99 in their jurisdiction.
Committee recommendation: Full council.
3. Presentation of Supplemental Agreement with Transpo for SR-104 Adaptive
System from 236th St. SW to 226th St. SW Project
Mr. Hauss explained the 1.25 mile SR-104 corridor from 236th St. SW to 226th St. SW has 5 signalized
intersections spaced approximately 1/4 miles apart with average daily traffic (ADT) of approximately
25,000 vehicles per day. This section of SR-104 does not have an existing traffic signal
communication/coordination system. This project will provide an adaptive system along SR-104 to
improve traffic flows and reduce vehicle emissions. It was originally anticipated this system could tap
into an existing WSDOT system to allow for wireless communication, but that will not be feasible,
necessitating the use of fiber optic cable. The supplement consists of the following:
• Addition
o $29,000 — Additional topographic survey along 212th St SW, 72rld Ave, 236th St SW, and
within the public works building property
o $8,500 — Addition of fiber optic cable to plans as part of the 30%, 60%, 90%, and 100%
PS&E
• Reduction
o $22,000 - Geotechnical investigation
The new contract total with Transpo is approximately $349,000 including management reserve. The
funding source is a $287,000 federal CMAQ grant for the design phase with $123,000 in local match.
Questions and discussion followed regarding whether fiber optics will be underground or aerial, and
whether wireless is less reliable.
Committee recommendation: Consent Agenda.
4. Perrinville Creek Culvert / BNSF
Councilmember Teitzel relayed a local civil engineer did a detailed analysis of the culverts under the
railroad tracks; the intent of this agenda item was to share it with public works staff and get their input.
The analysis seems to indicate there is potential for safety problems. He acknowledged some things in
the analysis are incorrect; for example, the report refers to two failing City -owned culverts under the
BNSF tracks; the City only owns one culverts.
07/11/23 PPW Committee Minutes, Page 3
Mr. De Lilla reviewed:
Perrinville
o Culverts
■ 30" concrete culvert owned by BNSF
■ 42" steel culvert owned by City
■ Joint BNSF/COE Video inspection project in 2013
■ Scoping for contract to inspect & video just City culvert in progress
- Part of data gathering process for project
- Working on including nondestructive testing. Similar to what we do to our steel
drinking water reservoirs
• Requires divers, since pipe cannot be bypassed
■ Abandoning City pipe likely not possible
- Discharges flow from -55 acre basin
- 8' below stream grade @ diversion structure
- Pipe will likely be lined via CIPP
- Diversion structure to be removed
■ BNSF & Talbot Road culverts to be replaced with bridge/culvert that is fish passable
Questions and discussion followed regarding comments in the citizen's letter that there is a risk of the
culverts collapsing and causing a train derailment, BNSF's inspection programs, hole in the steel culvert,
limited data and assumptions in the letter, emergency maintenance done by City crews, seeking
resolution with BNSF, federal funding for the Meadowdale Beach project, seeking grant funds, involving
all the parties in designing a project, and distance between the concrete and steel culverts.
Committee recommendation: No action required.
5. Public Works and Utilities Q1 Report
Mr. Antillon and Mr. De Lilla responded to council questions regarding residential and commercial water
rates, the City's NPDES goals, progress on the WWTP project, failure of a pump system in the WWTP
designed to move solids, hauling costs the WWTP is incurring, completion date for the WWTP project,
