2011-11-29 Work Session Kodiak Island Borough Assembly Work Session Tuesday, November 29, 2011, 7:30 p.m., Borough Assembly Chambers Work Sessions are informal meetings of the Assembly where Assembly members review the upcoming regular meeting agenda packet and seek or receive information from staff. Although additional items not listed on the work session agenda are discussed when introduced by the Mayor. Assembly, or staff, no formal action is taken at work sessions and items that require formal Assembly action are placed on regular Assembly meeting agenda. Citizen's comments at work sessions are NOT considered part of the official record. Citizen's comments intended for the "official record" should be made at a regular Assembly meeting.

ENGINEERING /FACILITIES DEPARTMENT la � � 071 e� • i; 4 MEMORANDUM DATE: November 7, 2011 FROM: Woody Koning, EF Director TO: Rick Gifford, Manager RE: Leachate Management Cost Options CC: Ken Smith, CM Nova Javier, Clerk The following is the report requested by the Assembly regarding estimated costs associated with each of the two leachate management systems available for the landfill expansion project. The options to choose from are: 1. Construct a pressurized pipeline and associated pumping equipment from the landfill to the WWTP operated by the City of Kodiak. 2. Construct on -site leachate treatment facility on the landfill property. We requested updated cost estimates from CH2MHill, the design firm, for these two options in order to assist the Assembly in deciding which option to focus MB engineering resources. We requested a cost of ownership for 15 years be included in the estimates. Please note the following qualifications from CH2MHi11: • This is a preliminary analysis. There are unknowns with costs that are not accounted for here that may sway the analysis in either direction. We can say that at this level of analysis, the Iifecycle costs appear to be comparable. (meaning it is reasonable, at this level of accuracy, to contrast the differences in life cycle costs over 15 years between the two options and determine that one will cost significantly more than the other using the given assumptions) • Onsite treatment comes out on top here because of the high NPV of annual disposal fees at the WWTP. • A major advantage of the onsite treatment system is based on max 400 gpm flow rate whereas the WWTP can only handle up to 200 gpm. The 400 gpm onsite is preferred during large flow events. This is a big advantage because of concerns with environmental review /permitting for emergency bypass discharge during large flow events. KIB will have more control with onsite system. The following tables are intended to show a very preliminary analysis of the different elements of the two options for contrasting the cost of each against the other. The construction cost is a conceptual estimate with a 30% contingency for both options. The NPV calculation assumes 2% inflation and a 5% discount. ONSITE TREATMENT PLANT ESTIMATE Construct Treatment Plant $5,100,000 (building, lighting, pumps, sludge dewatering, site work) Sludge disinfection system 50,000 (needed for sewage treatment) Operating Cost (NPV 15 years) 3,808,235 (1.5 FTE, WWTP operator, chemicals, lime, monitoring, etc.) TOTAL 15 YEAR COST $ 8,958,235 PIPED TO CITY WWTP ESTIMATE Construct Pipeline $3,000,000 (4 mi. includes pumps) Monitoring /Control Interface 200,000 (design & construct) WWTP Upgrades 700,000 (aeration) Disposal Fees for 15 Yrs 6,988,749 (NPV 15 Yrs) TOTAL 15 YEAR COST $ 10,888,749 Additional important considerations include • potential future development needs for sanitary sewage treatment facilities in the area • the borough would maintain continuous control of its leachate management and not be dependent on other agencies to accept leachate in the future BID ITEM Detail 2 (L,M,S,E,PE) CE-I21!/IHILL PROJECT: Kodiak Landfill OST ESTIMATOR: Butcher,K aka DESIGN STAGE: Preliminary ESTIMATE No.: 2011.0021 PROJECT No.: 354650 REV No /DATE: 2/October 27. 2011 PRELIMINARY Onsite Treatment Plant Protect name Kodiak Landfill OST Kodiak AK Estimator Butcher, K Labor rate table 2011 Labor Equipment rate table 2010 Equipment Job size 1 LS Duration 6 Mo Project Kodiak Landfill OST Project Number 354650 Market Segment Water Business Group WBG Estimate Class 1.5 Class 5 Design Stage Preliminary Region Southwest Project Manager Ian VanBlankenslein 0C Reviewer Bob Lawson/ROD Rev No. / Date 1/October 26, 2011 ENR COI Index 20 City @ 9147 ENR G01 Index Date October 2011 Estimate No. 0 Material Index 2863 Report format Sorted by' Bid (tem/Assembly 'Detail' summary Cost Index Alaska - Anchorage M:\ WBG\ Estimates .CNSLT\20111W- Treatment\354650 Kodiak Landfill Onsite Treatmentwrelim\Rev 2 Oct 27 10/27/2011 1:57 PM Property of CH2M Hill, Inc.

Every year one of the most important functions of the Borough Assembly is balancing use of economic resources against the costs of funding a quality education system. The first step in determining how much funding is available is to examine the financial resources of the Kodiak Island Borough (Borough). 1) Economic indicators The economy of the Borough continues to be strong. Several different indicators are used to make this determination. When we do our evaluation of the economy we only use data that can be verified. a) Assessed value of the Kodiak Island Borough The largest component of local funding for the school district comes from property taxes. The assessed value of the Borough continues to rise. Fiscal Total Year Assessed Value Assessed Value 2003 760,451,857 • 2004 770,636,765 1,200,000,000 2005 • 783,909,250 1,000,000,000 - • 2006 798,915,949 • 800,000,000 - — — — — 2007 805,681,814 • 2008 835,525,537 600,000,000 — — — — — 2009 r 870,770,562 400,000,000 — — — — — — 2010 896,893,679 • 2011 988,879,125 200,000,000 — — — — — — — — — 2012 • 1,039,223,833 0 ' 'LOct n,, 'L0 r, 'L ° °oi 'I- 1 1. , The assessed value of the Borough is expected to rise 2% next fiscal year (FY2013). This will be an increase of $21,000,000. At the current mill rate, this will increase school district property tax revenues by $190,890. Debt service on school district bonds will increase by approximately $800,000 in FY2013. The increase in property values will cover approximately $33,000 of this increase. To pay for the balance of this increase, the property tax mill rate will have to be increased by approximately .75 mills. b) Cash in banks The amount of money available in local banks continues to rise. Deposits in Fiscal Year Local Banks Deposits in Local Banks 2002 123,221,000 2003 120,352,000 200,000,000 2004 130,325,000 2005 133,370,000 150,000,000 2006 14 2007 140,915,000 100,000,000 /111W1 ' ' 2008 139,416,000 2009 175,141,000 50,000,000 ' ' 2010 192,242,000 0 ' 2011 194,289,000 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 c) Severance tax As you can see the value of the resources severed from the Borough has more than doubled over the past ten years. Most of our severed resources are renewable; i.e. fish and timber. The only nonrenewable resource that we are severing is gravel. Value of Severed Resources Value of Fiscal Severed 160,000,000 Year Resources 140,000,000 2002 78,709,622 120,000,000 , , , 2003 75,898,919 2004 86,453,297 100,000,000 - 00 2005 98,101,268 0,0 6 ,000 ■ i u IuI u I I I I I 2006 107,900,636 60,000,000 2007 125,398,952 40,000,000 2008 136,781,905 2009 124,875,143 20,000,000 , , ■ il 2010 127,245,238 - 2011 157,073,714 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 d) Sales Tax - Even though the Borough does not have a sales tax, it is useful to look at the City of Kodiak's sales tax data to measure the health of Kodiak's economy. } • In FY2010 the total sales receipts in the City of Kodiak were $414,087,791. The City of Kodiak realized $9,379,409 with a cap of $45 per transaction. This equals $1,563,234 per percent of sales tax.

We are anticipating that the State will reimburse us for 60% of the debt service on these bonds. When all of these bonds have been issued, the debt service cost to the Borough will be about $2,620,000. These payments will need to be funded with a mill rate increase of approximately 2.5 mills There are other projects related to the High School project such as the Kodiak High School Exterior Insulation and Window Upgrade for $596,020 and the High School Vocational Education /pool reclamation project for $4,840,788. These other projects are funded by bond issues, State and Federal grants, and local resources. b) Other school Projects In total, the Borough has $194,217,948 in ongoing capital projects for the school district. This is $14,289 for every man, woman, and child in the Borough. c) Borough capital projects The Borough has $24,532,089 in ongoing capital projects not related to education. Many of these projects have been substantially completed. One of the largest non - educational capital projects for the next several years will be expanding the landfill. d) Debt Service Debt service costs will to continue to rise. In the next several years it will go up 1.5 to 2.0 mills. This is a significant increase but the voters were aware of it when they approved the bond issue for the High School Renovation and Additions Project. e) Insurance As the value of our assets increases, the amount we pay for property insurance will also rise. We currently pay 4 cents to 5 cents per hundred for property insurance. Many of these projects will not increase our insurance costs but we will pay $50,000 to $100,000 more in property insurance. 3) Borough General Fund Budget The Borough must balance its use of economic resources between education and other functions. Some of these functions directly affect school district funding. An example would be assessing. While it is a Borough Department, the majority of property taxes collected go towards financing education. a) There should be no material changes in General Fund revenues in FY2013 i) Severance taxes for the first quarter of FY2012 are 26% higher than the first quarter of FY2011. ii) Interest rates are the lowest they have been for some time and it is doubtful they will rise in FY2012. iii) State revenue sharing has been approximately $750,000 for the last several years; I don't think it will change in the coming year. iv) Federal PILT, which accounts for 22% of the General fund budget, should remain at about $1,325,000 per year. v) State of Alaska raw fish tax, which accounts for 21% of the General Fund budget, should remain at about $1,250,000 per year. b) General Fund expenditures for FY2013 will remain fairly consistent with FY2012. i) There will be an increase in health insurance and staff has made it a priority to keep this increase as low as possible. ii) We are not anticipating adding or deleting positions from the Borough budget. At this time we are having a difficult time filling some of the vacant positions and I do not see that changing in the next year. iii) There will be increases do to Cost of Living adjustments to the salary scale. One of the most important tasks for the Assembly, Mayor, School Board, Borough Staff and School District staff is providing quality services to our residents at the lowest cost.
