City of Tukwila Jim Haggerton, Mayor INFORMATIONAL MEMORANDUM TO: Mayor Haggerton Utilities Committee FROM: Bob Giberson, Public Works Director BY: Mike Cusick, P.E., Program Manager DATE: November 15, 2013 SUBJECT: 2013 Annual Sewer Repair Program Project No. 91340201, Contract No. 13 -134 Change Order No. 1 Approval ISSUE Approve Change Order No. 1 to Contract No. 13 -134 with King Construction Co., Inc. BACKGROUND King Construction Co., Inc was awarded the contract for installation of side sewers to 6532 and 6542 Southcenter Blvd on August 6, 2013. Work began on the side sewer installation on August 19, 2013. DISCUSSION 1. During the first day of work, King Construction Co., Inc. began excavating for the sewer line up the hill from old Macadam Rd. The contractor encountered buried boulders greater in size than one half cubic yard. The boulders and ledge rock were found in remaining trenching for the project. The contractor's schedule allowed for 4 working days for excavating and installation of piping. With the removal of the boulders, an additional 3 days was needed to complete the project. 2. The Contractor had to concrete encase a 10 -foot portion of the sewer because it passed under a water main with less than 18" of clearance. 3. The Contractor was required to rotate the soil pipe at the 6532 Southcenter Blvd's crawl space so that it would exit in the front yard. When the contractor was in the crawl space, he determined that instead of 1 point of connection to the existing septic tank, there were 3. The contractor's schedule allowed 1 working day for installation of piping in the crawl space of the house. The change in scope required an additional day to complete the connection to the house. FINANCIAL IMPACT Contingency was set at 10% or $4,905.60 for this side sewer project. The additional scope of work included the extra time and effort required to excavate the unforeseen rock; plus the costs for concrete encasing the sewer line and rotating of the soil pipe under the house at 6532 Southcenter Blvd. The funds to cover this change order will come from the 55th Ave S Sewer Repair Project as that project had $31,964.50 remaining from the original $55,000.00 budget and the project was completed with no change orders. RECOMMENDATION Approve Change Order No. 1 in the amount of $28,825.85, including sales tax, to Contract No. 13 -134 with King Construction Co., Inc, for installation of the side sewer to 6532 and 6542 Southcenter Blvd and consider this item at the November 25, 2013 Committee of the Whole and subsequent December 2, 2013 Regular Meeting.

During the first day of work, King Construction began excavating for the sewer line up the hill from old Macadam Road. They encountered buried boulders greater than one half cubic yard in size. The boulders and ledge rock were found in remaining trenching for the project. The contractor's schedule allowed 4 working days for excavating and for installation of piping but the boulders and ledge rock added over 3 additional days of construction time required to complete the installation of the sewer line. 2. The Contractor had to concrete encase a 10 foot portion of the sewer because it passed under a water main with less than 18" of clearance required by the Washington State Department of Health. 3. The Contractor was required to rotate the soil pipe at the house at 6532 Southcenter Blvd. in the crawl space under the house so that it would exit in the front yard. When the contractor was under the house in the crawl space, he determined instead of one point of connection, there were three points of connection to the existing septic tank. These extra connections required about an additional days labor so the house would be connected to the sewer system. 4. Extend the contract with King Construction, Co. Inc. to December 1, 2013, so that Change Order No. 1 can be completed. 3 King Construction Co., Inc.

The crew was directed to encase the side sewer pipe in concrete at the water main crossing. This spreadsheet also includes the invoiced cost of the concrete as this work was done at the same time as the rock excavation occurred. This spreadsheet includes the excess cost of hauling the rock spoils for disposal beyond the amount included in the bid for dirt spoils. There is no excess dump fees as we found a site that would accept the rock spoils for reuse.

BACKGROUND The City hired CH2M Hill to update the current Surface Water Comprehensive Plan (SWCP) to reflect changes in regulatory requirements and drainage needs within the City. The current SWCP was completed in 2003 and does not reflect changes in regulations required under the City's National Pollutant Discharge Elimination System (NPDES) Permit, our current GIS inventory, completed CIP projects, the Tukwila South annexation area, nor newly identified needs. DISCUSSION The 2003 SWCP was reviewed and updated based on current and projected needs. Additional components were added to provide a more comprehensive review of the City's surface water system. The updated 2013 SWCP contains the following overall changes: • Drainage basin limits were revised based on new survey information • Tukwila South area was added • A map book was added showing all surveyed drainage facilities • The CIP project list was revised to reflect new and completed projects • A review was conducted on existing NPDES requirements to ensure full City compliance • A field survey was conducted to map culverts that block fish passage In additional, the 2013 SWCP makes specific policy recommendations designed not only to meet minimum regulatory requirements, but also to proactively provide improvements to the overall function of constructed and natural drainage systems. These recommendations are: • A new/revised list of recommended capital improvement projects • Increase environmental stewardship and education activities to promote awareness of and a sense of responsibility for surface water and natural drainage systems W:\PW Eng \PROJECTS1A- DR Projects\Surface Water Comp Plan (91041202)\ Info Memo - Plan Adoption .docx 7 INFORMATIONAL MEMO Page 2 • Provide better documentation, tracking, and reporting of inspections and enforcement actions • Provide proactive maintenance activities beyond those currently required to further reduce sediment loading within stream systems • Retrofit existing public surface water systems to provide water quality treatment by establishing an annual water quality capital project and dedicated funding • Develop a policy concerning ownership of new private drainage systems • Develop a policy concerning maintenance of existing private drainage systems to ensure that they are properly maintained • Develop a vactor decant policy and locate a permanent site to decant solids from street sweepings and catch basin cleaning • Further develop an inspection program for privately owned storm water facilities including hiring necessary staff to ensure private surface water systems are being properly maintained • Hire a 'habitat manager' to focus on habitat protection and restoration activities consistent with the WRIA 9 Salmon Recovery Plan An electronic copy of the 2013 Surface Water Comprehensive Plan has been placed on the City's website and is accessible through the following link: http://www.tukwilawa.qov/pubwks/swcomp/Surface%20Water%20Comprehensive%20Plan.pdf RECOMMENDATION Council is being asked to approve the Resolution adopting the 2013 Surface Water Comprehensive Plan and consider this item on the Consent Agenda at the December 2, 2013 Regular Meeting.

BACKGROUND On April 23, 2012, a public hearing was held to obtain feedback from Tukwila residents regarding a proposed mandatory garbage collection program. Nine residents testified with only one in favor of implementing a mandatory program. Additionally, three residents submitted written comments and all three opposed mandatory collection. After the public testimony, Council deliberated on the merits and demerits of the program and decided to defer the mandatory garbage collection decision to a later date. Council further directed staff to return to a committee a year after implementation of the new contract with Waste Management and revisit the subject. DISCUSSION The City has debated mandatory garbage collection since 1976. Undoubtedly, it is a challenging, controversial, and emotional topic. Opponents of mandatory garbage collection cite many reasons including loss of control in deciding how to handle their garbage disposal and the right to choose whether or not to purchase garbage service. Proponents cite environmental, esthetic, and health benefits, including the decrease in build-up and long-term storage of garbage in residential neighborhoods. Despite a slight increase in garbage subscribership since the implementation of the new contract with Waste Management in 2012, approximately 25%, or 883 of Tukwila's single-family residents have chosen not to subscribe for garbage/recycling collection services. Of the 883 non-subscribers, some may support mandatory collection and some may vehemently oppose the proposal regardless of the benefits and convenience. Attached is an updated version of the Mandatory Collection Information Sheet used during last year's deliberation and provides facts and issues for both opponents and proponents to consider. One important initiative that is not included in the information sheet merits consideration. Last year, City Council adopted the City's first Strategic Plan. Implementing a mandatory garbage collection program supports at least two of the Strategic Plan's goals by helping the City achieve/maintain a clean and inviting environment. Should the Utilities Committee/Council decide to pursue mandatory collection, a public hearing is recommended to obtain comments. After the public hearing, Council could consider the same three options provided during the April 23, 2012 public hearing: WAPW Eng \PROJECTS \Solid Waste \ InfoMemo-Mandatory Garbage Collection-LIC111813 gl.doc 11 INFORMATIONAL MEMO Page 2 Option A: Reject proposal to implement mandatory garbage collection. • Advantage(s): This option requires no additional staff time. Waste Management will not have to deal with issues related to non-complying customers and potential bad debt accounts. • Disadvantage(s): Non-subscribers will continue to dispose of garbage and recyclables through self-haul or other legal and illegal means. Accumulation of excess garbage and bulky items such as broken furniture and appliances on private property will continue to be problematic. Option B: Defer decision to implement mandatory garbage collection. • Advantage(s): The new contract contains a provision requiring Waste Management to reduce single- family customer rates by $0.64 per month should the City decide to exercise its option to implement mandatory garbage collection by November 1, 2015. Disadvantage(s): Same as Option A. Option C: Approve mandatory garbage collection services. • Advantage(s): The 3,500 total (2,617 current customers plus 883 non-subscribers) single-family residential customers would benefit from some of the lowest solid waste rates in the area, Collectively, they would save approximately $26,880.00 annually. Those who sign up for the minimum level service would pay a nominal fee of $4.89 (plus tax and fees) per month and receive monthly curbside garbage collection, unlimited every-other-week recycling, and access to the special annual curbside collection/recycling events. This annual event allows residential garbage customers to dispose of items such as appliances, furniture, and other bulky items. Implementation of a mandatory garbage program would help curb illegal dumping and accumulation of garbage on private property. The program supports City of Tukwila's Strategic Plan and would have a positive effect on Tukwila's neighborhoods. • Disadvantage(s): Additional staff time (City and Waste Management) would be required to manage challenges and issues related to mandatory collection implementation and enforcement requirements. FINANCIAL IMPACT If Council selects Option C and approves mandatory garbage collection, the 3,500 single-family residential customers would save approximately $26,880.00 annually. Additionally, utility tax revenues from solid waste and recycling collection services would increase. Assuming all 883 non-subscribers sign up for the minimum service, the annual garbage utility tax revenues would increase by approximately $3,108.00. This utility tax revenue could be used to offset illegal dumping/litter clean-up expenses or provide a subsidy to selected low- income households who cannot afford the monthly $4.89 (plus tax and fees) minimum service charge. Low- income seniors and low-income disabled customers are currently eligible for a 50% discount. RECOMMENDATION Information only at this time. Council is being asked to consider public comments and discuss Options A, B, or C in 2014 during the first quarter in a Committee of the Whole Meeting/Public Hearing with possible action during a subsequent Regular Council Meeting. Attachment: Mandatory Collection Information Sheet WAPW Eng 1 PROJECTS \Solid WastenfoMemo-Mandatory Garbage Collection-UC111813 gl.doc 12 Attachment 1 Mandatory Collection Information Sheet • What are the savings if the City proceeds with mandatory collection? Individual customers would save $0.64 /month on their rates. The total 2,617 current customers would save approximately $20,000 /year. • What percentage of customers currently have collection? Approximately 75% of Tukwila single - family customers have garbage collection (2,617 current single family customers /3,500 single family residents). • What do non - customers do with their garbage? Some self -haul to King County transfer stations or may use other legal methods such as dumping in their workplace dumpster (with permission) or sharing service with a neighbor. Other residents rely on illegal disposal including burning, burying, using commercial dumpsters (without permission), accumulating in rental spaces, or dumping. • Why should people have to pay for mandatory collection if they currently handle their materials legally? The new contract has been structured to provide a very economical service level that is actually less expensive than self - hauling. The lowest service level is once per month collection of one 32- gallon garbage cart (the cart is provided by Waste Management), unlimited every- other -week recycling and access to the City's annual curbside clean -up program where bulky material and appliances can be set at the curb at no additional charge. This service cost of $4.89 per month under the new contract is less than paying the minimum fee at King County's transfer station three times a year. • The savings don't matter to us - we just prefer to self -haul. King County has increased the minimum fee (currently $22). Legal self -haul will more than likely be less attractive in the future. • What about low - income households? As described above, the minimum service level is less expensive than other legal options. The $4.89 per month may be more expensive than illegal disposal, but illegal disposal increases costs to the community at large. • What about senior /disabled households? The new contract continues current provisions that allow eligible households a 50% discount on collection services. In that case, the monthly fee for the minimum service level would be $2.45 per month, which is far less than any other legal disposal method. • What are the net ratepayer costs of having or not having mandatory collection? If mandatory collection is implemented, the 3,500 total (2,617 current customers plus 883 non - subscribers) single - family households will save $26,880 annually. If all 883 current non - subscribers sign up for the minimum service, they would collectively pay a total of $51,814 annually. • Will mandatory collection help City's effort to curb illegal dumping, litter, and accumulation of trash /garbage on private property? Garbage and trash related code violations continue to increase in Tukwila neighborhoods. Tukwila Code Enforcement officials have wrestled with residents piling garbage in the back of trucks, on their decks, under their carports or on the ground for significant periods of time. Code Enforcement officials have also found some residents burying and burning garbage. Their caseload rose from 105 trash and garbage related complaints in 2011 to 130 in 2012. Most of the complaints were for accumulation of garbage, yard waste and bulky items such as furniture, appliances, etc. on private properties. Implementation of mandatory garbage collection will provide a basic level of service that includes monthly garbage collection, recycling service, and participation in the annual curbside collection of bulky items /white goods (furniture, appliances, electronics, washers /dryers, etc.) at no additional costs. Although implementation of mandatory garbage program may not totally solve illegal dumping and garbage related issues, services provided by mandatory collection would have a positive effect on Tukwila's neighborhoods.
