4. Online: www.soundtransit.org/FWextension

Information Only/No Motion Required

Item 3 – Consultant Services Agreement – Allen Brackett Shedd State Route

516 to S. 231st Way Levee Project:

Beth Tan gave a presentation to the committee about the SR 516 to 231st Way Levee

Project. Completing the SR 516 to S. 231st Way Levee adjacent to the Lakes Community

requires additional property from the condominium associations of Bridgewater III,

Bridgewater IV, and Regatta at the Lakes. This acquisition will not include any

condominiums, but will include common area property. North of this area the levee

adjacent to Marina Pointe will not need additional property, but will require a levee

maintenance inspection easement to complete the accreditation.

The consultant services agreement with Allen Brackett Shedd is to provide a real estate

appraisal of the impacted properties and assess the value of the project’s impacts. Their

3

http://www.soundtransit.org/FWextension



service includes impacted areas involving approximately 273 units with extensive public

involvement and communication with property owners.

This levee reach, in combination with the other levee segments along the Green River,

protects the Kent Valley businesses and residential areas from flood risks. Laporte

added that levee documents have all been reviewed by FEMA. The documents have also

been sent to King County Staff. LaPorte also noted that new levee work will meet 500

year flood protection standards.

Councilmember Ralph confirmed that we are purchasing property that is open space and

no structures will have to be moved.

Ralph MOVED to recommend Council authorize the Mayor to sign the Allen

Brackett Shedd Contract Agreement for the Real Estate appraisal services of

property on the State Route 516 to S. 231st Way Levee Project in the amount of

$58,000 upon concurrence of the language therein by the City Attorney and

Public Works Director. The motion was SECONDED by Higgins and PASSED

3-0.

Item 4 – Joint Funding Agreement for the Cooperative Data-Collection Program

with the U.S. Geological Survey:

Environmental Engineering Supervisor Alex Murillo noted that this is an on-going

program with the U.S. Geological Survey (USGS) for stream data collection. The City of

Kent will contribute $60,080 to the annual program costs of $106,205 with the USGS

providing the remainder.

These gages provide valuable information on stream and weather conditions, including

water surface elevations, flow levels and amounts of precipitation. Information is used

to calibrate stream flow models and increase the accuracy of city design of stormwater

flood projection models. The gages, through their link to internet web sites, allow staff

and the public to monitor stream flow levels from remote locations.

This contract will provide for operation, maintenance and data collection at five gages.

Two are located on Mill Creek, one on Springbrook Creek and two on Rock Creek.

Gage information is available to the public real-time at

http://waterdata.usgs.gov/wa/nwis/current?type=flow

This is an ongoing contract that is signed yearly with USGS. Council members Ralph

and Albertson mentioned that they have visited some of these sites and they have an

understanding of what the gages are.

Murillo was asked by committee members if the cost could be shared equally in the

future. Murillo will look into it for next year.

http://waterdata.usgs.gov/wa/nwis/current?type=flow



Ralph MOVED to recommend Council authorize the Mayor to sign the Joint

Funding Agreement for Water Resources Investigations between the City of

Kent and the U.S. Geological Survey upon concurrence of the language therein

by the City Attorney and Public Works Director. The motion was SECONDED by

Higgins and PASSED 3-0.

Item 5 – Information Only/Mill Creek - Springbrook Creek Basin Capital:

Environmental Engineering Supervisor Alex Murillo provided an update on City projects

along Mill Creek and Springbrook Creek. Murillo noted that a lot of focus is on levee

improvements to reduce flooding from the Green River. He went on to briefly explain

what is being done to prevent flooding in the valley creek systems.

• Mill Creek upper detention dam improvements, raising the dam 5.5 feet to allow for

more storage and reduce flooding under the Central Ave S stormwater force main

improvements project.

• We are installing 1.5 miles of pipe under the sidewalk along Central Ave to reduce

flooding in the valley near James St. The final phase of the project is to construct the

James Street pump station at Mill Creek.

• The Mill Creek, James Street to Central Ave flood storage and stream habitat

improvements project will relocate the stream and reduce flooding.

• 76th Ave S culvert replacement and stream improvements project; widen culverts and

reduce flooding.

• 64th Ave S channel culvert replacement project at S 226th St and Union Pacific RR

Spur will install larger culverts to reduce flooding.

• Green River Natural Resources Area flood storage and water quality improvements;

improving the regional storm water facility to reduce flooding.

• Upper Meridian Valley Creek flood protection and stream enhancement project will

move the creek away from properties and reduce flooding.

A slide related to the National Pollutant Discharge Elimination System (NPDES)

stormwater pond cleaning was presented.


Item 6 – Information Only/Vactor Site and Screener:

Jens Vincent Stormwater Supervisor gave a power point presentation on the soils

screener that was purchased with grant funds from the Washington State Department of

Ecology.

The purchase of the soil screener has allowed Public Works Operations crews to:

1. Filter out trash and debris from catch basin solids collected during cleaning and maintenance.

2. Aerate solids to speed the composting process 3. Eliminate the cost of renting a screener

5



4. Provide low-cost topsoil for roadside plantings

These elements are increasing efficiency, and allow staff to maintain their schedule of

catch basin maintenance and repairs while simultaneously saving money on rental costs

and staff time.

Vincent noted that a chase truck is being requested in the 2013/2014 budget. He

explained that a chase truck would provide tools, signage and traffic control for the

Vactor trucks when they are being used to extract soils.


Item 7 – Information Only/Adopt-a-Street Program Update:

Gina Hungerford gave a presentation regarding the City’s Adopt-A-Street program.

Since the successful inauguration of the Adopt-a-Street program in April, the program

has grown to 13 groups with more in the process of forming. 49 volunteers are picking

up litter on their adopted streets, making our City more beautiful.

The dedication and commitment of all these volunteers is making a big difference in

beautifying the city and helps to protect water resources.

Interested parties who would like to Adopt-a-Street can find more information at http://kentwa.gov/content.aspx?id=21445&terms=adopt%20a%20street. Or for more

information, contact Gina Hungerford at [email protected] or call 253-856-5549.


Item 8 – Information Only/Green Kent Day October 27th:

Matt Knox, Environmental Ecologist gave an informative Power Point presentation on

Green Kent Day. Knox noted that the Green Kent Partnership combines the talents of

Parks, Public Works and Kent volunteers to improve and enhance Kent’s 1,189 acres of

parks and natural areas. Approved by City Council in September of 2009, the program

trains volunteer land “stewards” to lead and teach other volunteers how to restore

Kent’s natural areas. To date, we have trained over 30 stewards and now have 13

actively encouraging and leading others.

Green Kent Day is scheduled for Saturday, October 27 we expect to recruit up to 100

volunteers to plant native plants from 9:00 am–12:00 pm at two sites – Morrill Meadows

Park and the Green River Natural Resources Area.

A VIP tour is also planned for State Representatives, Councilmembers, the Mayor and

other dignitaries the tour will highlight the Green Kent partnership and these two special

areas. A donated barbecue from Farrington Court will be held at the conclusion of the

event for all volunteers and VIP’s at Morrill Meadows Park.

Council members Ralph and Albertson commented that they will be at Green Kent Day

helping out. Knox encouraged people to go online to www.greenkent.org to sign up for

Saturday’s event. There will be tools available to use provided but people are

encouraged to bring their own as well.


Item 9 – Information Only/Sewer Collection System & Sewer Pump Stations:

Dave Brock, Utility Engineer gave a brief Power Point presentation on the sewer

collection system and sewer pump stations. Brock noted that Kent has approximately

211 miles of sanitary sewer system. Much of the system has reached the end of its

service life (50 to 70 years) and is in need of repairs or replacement. Brocks’

presentation gave an overview of the condition of the sewer infrastructure and touched

on damage from fats, oils and grease (F.O.G.).

Brock noted that in 1990, 25% of the sewer rate was for Kent and 75% for King County

METRO. In 2012, Kent’s sewer rate is down to 16% and 84% for King County METRO.

LaPorte commented that the increase in the last several years to the sewer rates have

been related to the costs to pay for King County’s Brightwater sewage treatment plant.

We will be delivering the need to increase rates very soon.


The meeting was adjourned at 5:32 p.m.

FILE NO. 0410-184-00

SCOPE OF SERVICES – GEOTECHNICAL

The purpose of our services is to conduct subsurface explorations and laboratory testing as a basis for developing geotechnical design recommendations related to the design and construction of the proposed James Street Pump Station in Kent, Washington. We understand that a storm sewer pump station will be constructed at 740 Woodford Avenue North, northeast of the intersection of East James Street and Woodford Avenue North. The site is located about 100 to 150 feet west of Mill Creek.

The pump station will include a vault consisting of three 10-foot-diameter concrete manholes connected with 6-foot-diameter concrete pipe. The vault base will be about 20 feet below existing site grades. The pump station will be operated using an electric pump with a back-up generator and an on-site fuel source. Up to 4 feet of fill will be placed to establish planned grades. The site will be surfaced with gravel and an asphalt concrete paved road will provide access. Roof structures will be constructed over the pump and generator. The roof structures will be supported on shallow pier foundations.

Our geotechnical scope of services in support of design will include the following items:

1. Review existing soil and groundwater information, including select in-house reports and published geologic maps.

2. Conduct a site visit prior to subsurface explorations to coordinate exploration locations and site safety issues.

3. Coordinate clearance and location of existing underground utilities in the project area. We will contact the Washington Utilities Coordinating Council “One Call” service prior to beginning explorations. We will also retain a private utility locate service to check for underground utilities at the site.

4. Drill two borings to depths of 40 feet below ground surface (bgs) using hollow stem auger drilling techniques. We will install monitoring wells in both of the explorations. We will also install an electronic piezometer in one of the wells. The electronic piezometer will collect and store groundwater level data from multiple readings per day.

5. Complete laboratory analysis of select soil samples. We anticipate that our laboratory program will consist of grain-size analyses and moisture content determinations.

6. Provide at least two rounds of groundwater monitoring. We will measure groundwater levels in the wells during installation to provide data for our design report. We will also retrieve groundwater data from the electronic piezometers and measure levels again prior to construction bidding to provide more up-to-date groundwater information for contractors prior to bid.

7. Provide a discussion of temporary shoring and dewatering. We are assuming that the dewatering and shoring system will be designed by the contractor. We will provide a general discussion of shoring and dewatering issues at the site and comment on the feasibility of different shoring and dewatering methods. We will also provide lateral earth pressures for the design of shoring systems and an order of magnitude estimate of dewatering quantities.

8. Provide recommendations for pipe bedding, pipe support and excavation backfill. We will provide recommendations for imported fill, reuse of on-site soil as appropriate and compaction requirements.

9. Provide recommendations for fill placement and compaction on the surface of the site. We will include recommendations for imported fill and compaction requirements.

10. Provide recommendations for shallow foundations and small drilled pier foundations for support of equipment pads and roof structures. We will discuss bearing surface preparation and shallow drilled pier construction. We will also provide design criteria, including allowable soil bearing pressures and allowable lateral resistance values for the design of foundation elements.

11. Complete buoyancy calculations on the proposed underground structures based on measured groundwater levels and the provided dimensions and weight of the structure. We will provide a discussion of methods for restraining the structure if buoyancy is determined to be a problem.

12. Prepare a geotechnical design report presenting the results of our explorations and summarizing our findings and recommendations. We anticipate this report will be available three weeks after site explorations are complete. We will also prepare a brief technical memorandum presenting the second round of groundwater monitoring data and revising our recommendations if appropriate. This memorandum will be provided during the spring or summer, after winter groundwater levels have been measured.

13. Provide additional consultation as required and requested. We anticipate that this could include meetings or plan review. We have budgeted 6 hours for a project engineer to cover this contingency.

Our scope and budget does not include any construction management, monitoring or inspections. We will provide a scope and budget for these services upon request.
