City of Tukwila Public Works Department - Henry Hash, Director - INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Committee FROM: Henry Hash, Public Works Director 2'7 BY: Hari Ponnekanti, City Engineer CC: Mayor Allan Ekberg DATE: October 4, 2019 (revised 10/18/19) SUBJECT: Public Safety Plan — Public Works Shops First Phase 1 Project No. 91630601 Master Plan Next Steps Allan Ekberg, Mayor ISSUE .A.p.prove the Public Works Shops Master Plan and funding for Public Works Shops Phase 1. Updotc on thc Public Works ! .", f'r thcirnT.:rovcrnents tc thc Heiser prf-Nporty. BACKGROUND The City hired SHKS Architects to conduct a Master Planning and Programming effort for the City's Public Works Maintenance Shops facilities in September 2018. Master Planning efforts are a good tool to loiisally implement overall facility improvements. The Public Works Master Plan envisions the redevelopment of over 13 acres of land, which will serve the Public Works Department into the future with planned growth through the year 2045. SHKS conducted several meetings with PW staff, visited the existing facilities, toured similar PW facilities in the region and developed a Master Planning and Programming Report. Several options were discussed and the selected Master Plan and the proposed tenant improvements to the Heiser site are the most practical and least expensive option. The current George Long building lacks sufficient spacing for routine maintenance and is also one of the most seismically deficient City building. The new site will be much safer for our employees and provides more space, therefore increasing operation efficiency. In addition, some of the equipment from Minkler Shops can also be moved to Heiser, allowing more space at Minkler Shops for maneuverability and productivity. ANALYSIS The findings from the Public Works Shops Master Plan are summarized in the attached updated PowerPoint presentation. The City took possession of the Heiser properties in July 2019 and will take possession of the UPS site in 2023. Master Plan Summary • The Public Works Shops First Phase 1 of the Master Plan focuses on relocating the PW Fleet Maintenance and Facilities divisions from George Long Shops to the Heiser property after seismic retrofitting and upgrades. The First Phase 1 will also include moving the Police vehicle evidence storage and spoils from the Longacres site. • The Longacres site will need to be vacated and moved to the Heiser site by 2021. To meet federal NPDES reaulations. spoils need to be stored in a covered site. • Public Works staff a ree that the best option is to move George Lona and Longacres operations to the Heiser Building. • George Lona was chosen to move to the Heiser Building, after necessary renovations, as the George Lona Building is seismically and environmentally deficient and is hazardous to City employees. • The Fleet mechanics work full-time in George Long as opposed to other Public Works employees that are mainly in the field. The George Long facility does not have an adeauate exhaust system and does not meet regulatory requirements. • As George Long is seismically deficient, if there is an earthauake and the buildina is destroyed, the entire City would be without the facilities and fleet divisions to assist with Police, Fire and other emergency operations.

Phase 2 - Possession of UPS site in 2023. Build Administrative offices and relocate Minkler. Cost estimate of $33 million. At the completion of Phase 2, all Public Works employees will be relocated to safe and efficient facilities. Phase 3 — Build new Fleet Maintenance Building, demolish Heiser Building. and install covered storage for $37 million. At the end of Phase 3, all future needs will be met with the entire buildout of the Heiser and UPS sites. PHASE 1 FINANCIAL IMPACT Expenditures 2019 Budget Budget Request Land Purchases $ 25,334,123.00 $ 30,000,000.00 Contracts & Demolition 856,928.88 PW Shops First Phase General Fund $ 2,200,000.00 Utilities 2,200,000.00 Total $ 26,191,051.88 $ 30,000,000.00 $ 4,400,000.00 Budget Balance $ 3,808,948.12 SHKS estimates that the PW Shops gr-st-Phase 1's costs will be $5.8 million and soft costs at $2.4 million, for an estimated total project cost of $8.2 million. Project soft costs include design fees, construction management fees, construction contingency, and sales tax. 2 W \PW Eng \PROJECTS \A- BG Projeets \ 01 Public Safety Plan \PW Shops First Phase (91630601)\Info Memo Master Plan Round 2 101819 a docx Informational Memo Page 3 The 2019 CIP's PW Shops budget is $30 million and to date $26,191,051.88 is estimated to be spent, which leaves a balance of $3.809 million. To complete the PW Shops gr-st Phase 1 at an estimated cost of $8.2 million, additional funding of $4.4 million is needed. The current funding has the PW Shops split 50/50 between the General fund (Streets. Facilities. & Fleet) and the Enterprise funds (Water, Sewer, & Surface Water). To continue with this 50/50 division, the General fund will need to budget $2.2 million and the Utilities would fund the remaining $2.2 million. Both Water and Sewer Utilities appear to have sufficient unreserved fund balance to absorb the additional costs, further analysis is needed to determine if the Surface Water utility can absorb the additional costs with the current rate model. There is funding available in all three of the Water/Sewer/Surface Water Utilities to fund the $2.2 million that will not impact utility rates or capital improvement proiects. FINANCING PLAN To fund the gap of $2.2 million in the General fund, funds can come from two sources. A transfer of $1 million from the general fund to the arterial street fund is currently budgeted in 2020. Because there is currently a healthy fund balance due to impact fees exceeding budget, the budgeted transfer can be redirected to the PW Shops project fund. Additionally, the 2020 general fund budget has a budgeted surplus of $1.4 million and could be utilized to fund the remaining request of $1.2 million. f. r /NV, +In rs1 +inn n k r n Due to favorable interest rates in the bond market, coupled with the City's upgrade in rating from AA to AA+, total debt service for the 2019 LTGO bond issue was $3.6 million less than budaeted attached in u dated financing schedule) The The resulting savinas will be realized in the general fund and utility funds over the life of the bonds, which is 20 years. The general fund will realize savinas of approximately $2.8 million and the utility_funds will realize a combined savings of $800,000. Minkler Shops Interim Improvements Until we take possession of the UPS site in 2023, Minkler Shops will require some improvements in the interim. Currently there are limited bathroom facilitiesonly one showerand the locker room does not have adequate space. Proposed improvements include an expansion of the men's restroomrelocating the locker room and building a new mud room. Also proposed are safety and security upgrades that include additional yard Iiqhtin and main gate improvements. The existin sate is currently not automated and left open durina the day as staff come and go The cost estimate for the Minkler Shops Interim Improvements are $500.000 and would be included in a new CIP proiect with funding from the Utility Enterprise funds.

It is anticipated the City will provide updated information electronically. Update Sewer Basins and provide an updated map for City review and confirmation. 302. Identify Primary Collectors and Lift Stations. The City will identify primary collectors and lift stations for potential flow monitoring and inclusion in the hydraulic model (Task 600). It is anticipated the collectors will be "skeletonized" to only include pipes greater than 12-inch and 8-inch pipes needed to represent flow conditions from sewer basins. To assist with future tasks, the City will need to provide invert elevations for the selected primary collectors and information onLift Stations. 303. Identify Flow Monitoring Locations. Identify recommended locations in install temporary flow monitoring devices in the gravity system at up five (5) locations to measure primary collectors and or Lift Stations south of I- 40S.Anadditiona|two(Z)flovvmonitorsnnphmarycoUectorsor|iftstationsvviUbeaddednorthnf|'4O5,as directed by the City. Flow monitoring locations will be provided to the City to confirm their suitability for meter installation. 3U4'Flow Monitoring ADS will provide temporary flmwmonitornguepvicesto[onsultanttocoUatthee(]) months of flow data up to seven (7). After completion of the monitoring, ADS will provide a Rain Dependent Inflow & Infiltration (RDI/1) Analysis and an electronic report. The work will be performed in three phases as set forth below: a. Phase|-YNobi|ization u' Site Locations ADS will work with the Consultant and the City toidentify/verify the seven h1 locations for monitor installations. Upon approval by the City, additional locations may be added per the optional costs inthe budget. a. Site Inve»tigation ' Once the installation sites are provided toADS, ADS field cevv(s)will perform site investigations. ADS will utilize astandard two (z) person field crew for fieldwork and comply with Federal standards for confined -space entry. The proposed flow monitoring location will be located, inspected, and verified for hydraulic suitability. ADS will also check for debris inthe manhole that could impact data quality and coordinate any required cleaning efforts with the City. 62 ADS field crews will look for evidence and signs oferratic flow patterns. ADS will also investigate adjacent manholes inorder tuidentify the best monitoring locations. I Site Reports Site reports will be generated upon completion of the site investigations. The site reports will include a sketch of the general location, physical characteristics and diameters of the proposed monitoring locations, manhole depths, flow measurements, and other comments pertinent tuthe location such asany special traffic o/safety issues. Final site locations tobe approved bvthe Consultant. 4. Equipment -ADS will utilize wireless ADS@ Model Triton+ T11 flow monitors during the course of this project. Atypical monitor installation will include anultrasonic deothsenso/thatviUbemoontedat the invert of the pipe, a redundant pressure depth sensor; and a Doppler velocity sensor also mounted atornear the invert. Monitor Activation Once installed, the monitor will beactivated and set totake readings at5- minute intervals. ADS Field crews will take manual depth readings with a ruler and velocity readings with a portable, instantaneous velocity meter in order to confirm the monitor is collecting accurate data based onthe actual existing hydraulic conditions ateach location. b. PhaseU Flow Monitoring �. Flow Monitoring Once the monitors are installed and verified tobeinworking order, ADS will monitor for a period of four (4) calendar months ("monitoring period"). This initial monitoring period can be extended based on mutual consent and written agreement of additional work and price for such additional work. Anticipated flow monitoring locations are listed in Table 1. Upon approval of the City, the flow monitoring may be extended by up to two months per the optional costs in the budget. a. Data Collection and Equipment Maintenance - ADS will collect data from each monitoring location remotely using telemetry on a daily schedule (for sites with good wireless signal). The ADS project team will review the data weekly to ensure each monitor is running properly meeting the project objectives as well ADS'standards. ADS Field Crews will perform site confirmations, site maintenance which may include, cleaning the sensor(s), moving, changing or replacing any failed component ateach monitor location. 3. Demobilization Field crews will continue data collections and confirmations (as necessary) until the end ofthe monitoring period. Once authorized, crews will immediately begin removing the flow monitors and deliver final data tuthe data analyst. C. Phase III Data Editing, Analysis and Reporting i. Data Analysis Upon completion ofthe monitoring period, atrained ADS Data Analyst will begin to finalize the data collected for each monitoring location. The data analyst will directly calculate flow using the continuity equation from recorded depth and average velocity data. Flow quantities as determined bvthe continuity equation will beplotted. z. S|i/icerRD|/|Analysis For each of the flow monitoring location, the analysis will characterize the average dry weather flow conditions and RDI/l calculations for all significant wet weather events, an assessment ofhydraulic performance under such conditions. The results ofdry weather and wet weather performance will be plotted on maps of the sewer sheds to make it easier to understand where RDI/I originates. The Shicer.com section of the Report will include the following items: � Dry WeatherAnalysis — A characterization of the conditions observed during weekday and weekend periods of the flow monitoring period during dry weather periods, excluding periods of extended system recovery to previous rain events. Summarized as a time -series hydrograph of the average diurnal flow quantities for weekday and weekend dry weather periods. S.

TASK 400 — FLOW PROJECTIONS The objective of this task is to develop the sewer flow projections for the sewer service area for the current (2019), lO-year,and build -out (maximum density) scenarios. Sewer flows will bebased onthe flow monitoring inTask 300 and the City's demographic projections. A new hydraulic model will be created and used to estimate future wet weather flows. The model will include the developed area south of 1405 and up to two (2) sewer basins north of4O5. This will not be an all pipe model of the system. The information developed in this task will become Chapter Flow Projections. This task includes the following activities: TASK 4OOA(__TiV|T|E,S 401 Data Acquisition. Data requests will be provided at the kick-off meeting and as needed throughout the project. The City will provide: • Current Nprogram. • Summary of|/|projects completed since the 2Ol3Plan. • Sewer connections bycustomer class. • Sewer conservation flow reduction rate. • Map with direct connections toKing County wastewater system. • Data on number, horsepower, capacity, design point for all pumps at the City's Lift Stations. • Lift Stations runtime. • City Planning Department existing and future populations and employment based on PSRC's 2040 Vision demographic projections and more current planning for the service area.

The 10-year growth rates will be consistent with the Comprehensive Water Plan. The build -out projections are anticipated to be based on Comprehensive Plan land use. 404. Design Storm. A design storm has been developed from a long term historical rainfall record at a number of sites near the City. Rainfall data from the ongoing city monitoring program will be reviewed and evaluated to determine if the design storm previously identified for wet weather flow modeling should be revised. The more recent data will also be used to evaluate any local rainfall variability and trends. This review will be prepared to prooidetheCityvvithadefensib|e^Design"sto/mthatemo|ates|oca|vveatherpatterns 405. Develop Existing Dry Weather Flows by Basin. Utilize existing land use maps to develop or confirm average dry weather flows (ADWF) for the modeled sewer basins. The flows will be confirmed with the flow monitoring data as well as the available flow data from the lift stations. Existing land use and currently served areas will be used to estimate flow factors per acre per land use category. The flow factor will be customized to match the observed existing ADWIF and will be used to develop flow projections. For basins without measured flow data, flow factors will be assigned from a measured basin with similar land use characteristics. 406.Deve|op 10-year and Build -out Dry Weather Flows by Basin. The City's comprehensive plan and any additional information on housing densities, commercial and industrial uses will be used along with the flow factors developed in the above task to determine the ultimate development acreage and the ADWIF for build -out conditions for uptosewer collection system. 407. Create Hydraulic Model. Using the most recent information from the City's GIS data, create a sewer system hydraulic model using Innovyze lnfoSWIVIM software. The model will include the developed area south of 1405 and up to two (2) sewer basins north of 40S. The model will include lift stations and primary collectors, and does not include the laterals, branches, or smaller truck sewers serving individual parcels within the basins. The City's existing GIS ArcView ".shp" files will be used to import the collection system data into the hydraulic model. If not available in the G|S, the City will provide invert elevations at key locations to construct the model. Add |nft station controls provided by the City to simulate realistic lift station operation. Estimate likely boundary conditions at connections King County transmission mains, asrequired. The up to seven (7) basins associated with flow monitoring will be further divided into mini -basins for sanitary and wet weather loading in the model. These mini -basins will group parcels that contribute to common branches and trunks, and will beconnected tothe modeled primary collector orlift station atthe appropriate location. 408. Meeting No4 - Hydraulic Model Creation.. Facilitate a meeting with City staff to review and confirm the elements of the hydraulic model. City staff may be requested to perform field verification of model elements based on this meeting. 409. Calibrate Existing Dry Weather and Wet Weather Flows. The existing dry and wet weather flows will be calibrated based upon the flow monitoring data, and rainfall data provided by the City as well as additional data available from the [ity's S[ADAsystem for optoseven (7) locations inthe collection system. Existing flow depths and velocities will also bechecked and calibrated. The first step istocalibrate the model todry weather flow conditions. Flow monitoring data will provide custom hourly diurnal curves that establish the daily flow patterns for each metering basin. Model results will be compared to measured flows to check for agreement between model results and measured flows. Model parameters will be adjusted, as needed, to best match the flow monitoring and SCADA data. It is assumed that the City will provide SCADA data in electronic format. Page ot17 66 Once the dry weather calibration is completed, the wet weather calibration is conducted. Rainfall information will aid in developing the required rainfall -derived infiltration/inflow (RDI/1) estimations that enter the collection system during a storm event. Wet weather calibration consists of using three storms that occurred during the flow monitoring period. It is recommended that the use of a single calibration period incorporating a number of independent rainfall events should be considered whenever possible. Model results will be reviewed and adjusted, asneeded, tobest match the flow monitoring, rainfall and SCADAdata. The flows from unmetered basins will be developed as best possible using a mass balance between the available data, and proportioned as best as possible based on development type, age, pipe material, and extent of collection system components. The hydraulic model will be calibrated in accordance with international modeling standards. The Urban Drainage Group from the Chartered Institution of Water and Environmental Management (CIWEM) has established generally agreed upon principles for model verification. The dry weather and wet weather calibration will focus on meeting the recommendations on model verification contained in the "Code of Practice for the Hydraulic Modelling of Urban Drainage Systems," published by CIWEM (November 2017). 410. Meeting No. 5 - Model Calibration. Consultant will conduct a workshop (Meeting No. 5) with the City to summarize the model calibration results.

Al|ocatetheexistingandl0-yearandboi|d'ootpnojecLionofsewenedpopo|ation and employment provided by the City Planning Department to Sewer Basins. The 10-year growth rates will be consistent with the Comprehensive Water Plan. The build -out projections are anticipated to be based on Comprehensive Plan land use. 404. Design Storm. A design storm has been developed from a long term historical rainfall record at a number of sites near the City. Rainfall data from the ongoing city monitoring program will be reviewed and evaluated to determine if the design storm previously identified for wet weather flow modeling should be revised. The more recent data will also be used to evaluate any local rainfall variability and trends. This review will be prepared to provide the City with a defensible "Design" storm that emulates local weather patterns 405. Develop Existing Dry Weather Flows by Basin. Utilize existing land use maps to develop or confirm average dry weather flows (ADWF) for the modeled sewer basins. The flows will be confirmed with the flow monitoring data as well as the available flow data from the lift stations. Existing land use and currently served areas will be used to estimate flow factors per acre per land use category. The flow factor will be customized to match the observed existing ADWF and will be used to develop flow projections. For basins without measured flow data, flow factors will be assigned from a measured basin with similar land use characteristics. 406. Develop 10-year and Build -out Dry Weather Flows by Basin. The City's comprehensive plan and any additional information on housing densities, commercial and industrial uses will be used along with the flow factors developed in the above task to determine the ultimate development acreage and the ADWF for build -out conditions for optosewer collection system. 407. Create Hydraulic Model. Using the most recent information from the City's GIS data, create a sewer system hydraulic model using Innovyze InfoSWMM software. The model will include the developed area south of 1405 and up to two (2) sewer basins north of 405. The model will include lift stations and primary collectors, and does not include the laterals, branches, or smaller truck sewers serving individual parcels within the basins. The City's existing GIS ArcView ".shp" files will be used to import the collection system data into the hydraulic model. If not available in the GIS, the City will provide invert elevations at key locations to construct the model. Add lift station controls provided by the City to simulate realistic lift station operation. Estimate likely boundary conditions at connections King County transmission mains, asrequired. The up to seven (7) basins associated with flow monitoring will be further divided into mini -basins for sanitary and wet weather loading in the model. These mini -basins will group parcels that contribute to common branches and trunks, and will heconnected tothe modeled primary collector orlift station atthe appropriate location. 408. Meeting No4 - Hydraulic Model Creation.. Facilitate a meeting with City staff to review and confirm the elements of the hydraulic model. City staff may be requested to perform field verification of model elements based on this meeting. 409. Calibrate Existing Dry Weather and Wet Weather Flows. The existing dry and wet weather flows will be calibrated based upon the flow monitoring data, and rainfall data provided by the City as well as additional data available from the City's SCADA system for up to seven (7) locations in the collection system. Existing flow depths and velocities will also bechecked and calibrated. The first step istocalibrate the model todry weather flow conditions. Flow monitoring data will provide custom hourly diurnal curves that establish the daily flow patterns for each metering basin. Model results will be compared to measured flows to check for agreement between model results and measured flows. Model parameters will be adjusted, as needed, to best match the flow monitoring and SCADA data. Itisassumed that the City will provide SCADA data in electronic format. Page otD m1,SP_*p, 87 Once the dry weather caUbmtoniscomp|eted,thewetweathe/o*|ibmtionismnndocted.Ra|nfaUinfonnadonviU aid in developing the required rainfall -derived infiltration/inflow (RDI/1) estimations that enter the collection system during a storm event. Wet weather calibration consists of using three storms that occurred during the flow monitoring period. It is recommended that the use of a single calibration period incorporating a number of independent rainfall events should beconsidered whenever possible. Model results will bereviewed and adjusted, asneeded, tobest match the flow monitoring, rainfall and S[ADAdata. The flows from unmetered basins will be developed as best possible using a mass balance between the available data, and proportioned as best as possible based on development type, age, pipe material, and extent of collection system components. The hydraulic model will be calibrated in accordance with international modeling standards. The Urban Drainage Group from the Chartered Institution of Water and Environmental Management (ClWEM) has established generally agreed upon principles for model verification. The dry weather and wet weather calibration will focus on meeting the recommendations on model verification contained in the "Code of Practice for the Hydraulic K8ode||ingofUrbanDrainageSystems,^pob|ishedbyOVYEK4(November2Ol7). 410.
