FARRELL, DIRECTOR OF ENGINEERING SUBJECT: FY 2007 -08 INITIAL CAPITAL PLANNING WORKSHOP INTRODUCTION In preparation for the Board Capital Planning Workshop on November 30, 2006, 1 have summarized the material we will be covering in this memo. If you have questions, this information, with additional detail, will be reviewed in the workshop. We routinely hold a Capital Planning Workshop in the fall to set an estimated dollar amount for our capital program for the following ten years. We have found this approach to be very helpful in narrowing the scenarios and considerations for the January Financial Planning Workshop in which the Board this year will be asked to review different rate setting scenarios and give direction to staff. By fixing the level of capital expenditures, approximately 40 percent of District overall spending, the possible budgeting scenarios become more limited and understandable. If the scenarios in January lead to some concerns about capital revenue and expenditures, adjustments can be made at that time and incorporated into the draft Capital Improvement Budget and Plan, which is brought to the Board in a second FY 2007 -08 Capital Planning Workshop in April. BASELINE RENEWAL AND REPLACEMENT PROGRAM In January 2000, staff developed and recommended a baseline for investment in our capital facilities which assumed replacement of all assets every one hundred years. This equates to a reinvestment of 1 % of the estimated replacement value. At that time the total replacement value of our facilities was estimated at $2.1 billion and therefore the annual investment was set at $21 million. This amount has been increased for inflation at 3% per year. This is a modest increase as building costs have increased significantly more than 3% per year since January 2000. This 3% annual increase brings the recommended reinvestment for renewal and replacement of existing assets to $26 million for the next fiscal year, year 2007 -08. Expenditures for significant projects to increase capacity are in addition to this baseline renewal and replacement program, as are projects to address changing regulations. HISTORICAL PERSPECTIVE Since fiscal year 1999 -00, District capital spending has ranged from a low of $19.8 million in 2002 -03 to a projected high of $40.9 million for the current fiscal year, 2006- 07. This wide variation has been due in large part to the conscious effort to defer needed projects in fiscal years 2001 -02 through 2003 -04, when the permanent loss of ad valorem tax was feared. During this same time period District capital revenue has also varied significantly, as shown in the following figures. This variation is due to changes in three revenue sources, ad valorem tax, Dougherty Valley capacity fees and the capital component of the sewer service charge (SSC). The capital component of the sewer service charge is the one revenue source that is controlled by the District. In some years adjustments have been made to reduce the capital component of the SSC and allocate more SSC to operating and maintenance costs in an effort to avoid increasing rates. In other years the capital component has been raised to fund needed projects. On average, capital revenues have closely matched capital expenditures. Over the seven years shown on the figures, the average annual revenue was $23,400,000 and the average annual expenditures were $23,800,000, a less than 2% difference. Average budgeted revenue was $21,500,000 compared to average actual revenues of $23,400,000. In fiscal years 2003 -04 and 2004 -05 there was a sharp increase in capital revenue due to the unanticipated rapid build out of the Dougherty Valley. In addition, ad valorem taxes were not lost to the extent feared. Thus, the Sewer Construction Fund Balance increased for the three period from fiscal years 2002 -03 to 2004 -05. PROJECTED FISCAL YEAR 2006 -07 EXPENDITURES /REVENUES Last year at this time we presented data to show that revenues from the Dougherty Valley connections were coming in to District coffers faster than expected, resulting in a significant increase in the Sewer Construction Fund balance. As discussed above, over several prior years, there had been a conscious effort to defer needed projects due to the uncertainty associated with the ad valorem tax revenue. In fact, much of the ad valorem tax was retained, contributing to the increased Sewer Construction Fund balance. Therefore, last year staff recommended increasing capital program expenditures to levels greater than revenues for several years and funding the needed projects partially from the Sewer Construction Fund balance. These needed capacity and regulatory driven projects included the expansion of the ultra violet disinfection facilities, a wet weather discharge point to increase the wet weather discharge capacity, a study and implementation of improvements to increase furnace capacity and reduce mercury in the effluent, the extension of the A -line from Buchanan Fields Golf Course to the intersection of Meridian Park Boulevard and Galaxy Way, and the expansion of the Primary Sedimentation Tanks. Since that time, the pace of building has slowed and the Dougherty Valley connections are expected to take place over a longer period of time. Therefore, the projected revenue from capacity fees in 2006 -07 has been adjusted downward.

As you can see, the Dougherty Valley revenues are still expected within the ten year planning window. On the expenditure side, a number of project bids have come in higher than expected. In addition, some needed projects have been increased in scope. On balance, the fiscal year 2006 -07 projections now call for drawing down the Sewer Construction Fund, instead of increasing it as previously budgeted. This is consistent with the last year's recommendation to use accumulated funds in the Sewer Construction Fund to run the capital program in deficit mode and fund needed projects. A comparison of budgeted vs. projected capital program activity for fiscal year 2006 -07 is contained in the following table. 2006 -07 Capital Program Budgeted Activity Projected Activity Total expenditures $34.8 million $40.9 million Alhambra Valley mainlines $0 million $1.5 million Total revenue $38.8 million $36.1 million Variance +$4 million -$6.3 million SCF balance 6/30/07 $59.8 million $49.5 million As discussed in previous years, the Sewer Construction Fund balance acts as the bank to fund all District operations. This is necessary because SSC revenue and property tax revenue are collected by the County on the tax roles twice per year. For the intervening six months, the District self funds its operation and maintenance functions as well as the capital program. The cash flow needs dictate that the Sewer Construction Fund balance be maintained in the neighborhood of $30 million. Therefore, even with the significant shift of more than $10 million from budget to projections, there is still an adequate balance to allow the capital program to run in a deficit mode for several more years. RECOMMENDED 2007 CAPITAL IMPROVEMENT PLAN FY 2007 -08 TO FY 2016 -17 Staff has developed a ten -year capital expenditure plan which budgets for a baseline of $26 million per year to fund renovation, renewal and replacement projects for a ten -year total of $260 million in June 2007 dollars. Staff has supplemented this baseline with approximately $34 million in needed capacity and regulatory expenditures between fiscal years 2007 -08 and 2011 -12, as shown in the following figure. This approximates the time over which the remainder of the $55 million in Dougherty Valley revenues are expected to come in to District coffers. The Dougherty Valley revenues will offset a large portion of the supplementary $34 million in needed projects. In addition, there may be a need for two large projects, a capacity driven primary sedimentation tank expansion project in fiscal year 2010 -11 ($20 million) and additional incinerator improvements to meet mercury discharge regulations, in fiscal year 2013 -14 ($30 million). The District ten year plan is developed each year to match needed expenditures with revenues over the ten year planning window. This works well for smaller projects, but for larger projects such as the two potential projects mentioned above, annual revenues C LL Z' Z a cc U V �O L CL D V C) °o °o o °o o °o °o 0 0 0 0 0 0 0 0 0 0 0 0 0 0 °o 00 00 00 0 0 at 0 C MT N O Co c0 IV N 64 60 64 G4 to vi 64 O`S �o z �o z o`'61 00 c� SO0 O4-1 } "o ;� o� toe, Aso o� s0 �4-1 Aa�o 02 za `o `off oQ s ss� m c m m m m U- U co a N U m m m m m LL co CL ca ml �i co m', ■' co O N r d' N o � N L �+ r M = O N /� CL § x T" fp W N c �+ CD ..

This leaves two funding options for large projects, either a significant rate increase during those years when these large projects are implemented, or bond funding. In order to evaluate these two alternatives, two tables showing expenditures and revenues were prepared and the appropriate capital component of the SSC was calculated. These tables are attached to the memo as an appendix. A graph comparing the SSC capital components for each alternative was developed and is shown in the following figure. As shown, using the bond funding approach, these two large potential projects can be implemented with an average capital component increase of less than $1 per RUE per year over the next nine years, from $49 to $53. If these projects are funded out of rates, the capital component of the SSC must be increased by over $50 in a three year period, from $37 to $89. As shown by this analysis, for large capital projects, bond financing is the preferred approach. It minimizes rate impacts and allocates project costs to the future rate payers who will benefit, instead of requiring current rate payers to bear the entire cost. Thus, should large projects such as those described here be required in future years, staff will recommend that bond financing be considered. This year, unlike last year, projects to meet new regulatory requirements are budgeted to the best of our ability. Our understanding of our potential new permit limits has improved over the last several months in numerous discussions with the Regional Water Quality Control Board (RWQCB). It is very likely that a project to remove mercury from the incinerator air scrubber water will be required to allow compliance with our new effluent limits for mercury. Staff is continuing to evaluate possible treatment options and has included a preliminary budget of $5 million in the treatment plant program expenditures for fiscal year 2008 -09. If treatment of the scrubber water is not adequate to meet the mercury requirements, a much more expensive option would be the installation of state of the art dry scrubber technology on our existing multiple hearth incinerators, or the construction of a new fluidized bed incinerator with this same technology. The dry scrubber technology removes mercury from the incinerator emissions using dry powdered activated carbon and thus eliminates the high mercury content in the scrubber water. The cost of these mercury reduction alternatives ranges from $15 million to $50 million. Staff has included $30 million in fiscal year 2013 -14 for such a project and recommends that, if needed, bond funding be considered. In conclusion, the District is in a very sound financial position with respect to its ten year capital plan, and should be able to fund needed baseline renewal and replacement as well as needed capacity and regulatory projects to minimize rate impacts, even if bond financing would need to be considered for major projects. RECOMMENDED FISCAL YEAR 2007 -08 CAPITAL IMPROVEMENT BUDGET The recommended fiscal year 2007 -08 Capital Improvement Budget includes $26 million for baseline renewal and replacement projects and an additional $15.3 million for needed capacity and regulatory projects for a total recommended expenditure of $41.3 million. The allocation of the recommended $41.3 million among the four programs is as follows: V c w= W U- 0 ■ o o Ua CL V LPL i IM J V W ._ o O La co 'i d CL 3 E CO V LO o LO o to 0 N O fl- LO N T- T- 3nN aad $ e6mic) aoiAies jemeS jo }ueuodwoo le4!deo T r 0 N T r 0 N u M 0 N M N_ 0 N r 0 N 0 0 N 0 0 N rn 0 00 0 0 N OD O 0 0 N 00 co U") U") O d r r = O M m = N N c U.

Staff will be working to develop the detailed budget document using the above preliminary figures as modified by the November 2006 and January 2007 Board Workshops. Many of the projects have already been defined. Others will evolve and emerge as we prepare the budget document over the next six months in anticipation of the second Board Capital Workshop in April 2007, when the detailed draft Capital Improvement Budget is reviewed with the Board. A review of the preliminary 2007 -08 Capital Improvement Budget for major projects and areas of emphasis follows. Treatment Plant Program The major projects planned for the treatment plant program in 2007 -08 can be placed in two major categories, wet weather issues and reliability improvements. Projects and preliminary estimates of expenditures are as follows. Category Project Annual Expense % Treatment Plant Program Wet Weather $3,920,000 30% WW Protection $1,000,000 WW Bypass $1,220,000 UV WW Capacity $1,700,000 Reliability $6,000,000 50% Plant Controls $800,000 Service Air $1,225,000 Solids Handling $1,500,000 Standby Power $2,475,000 All Other $2,380,000 20% Total $12,300,000 100% All of the above projects have been discussed with the Board in the past and were included in last years CIB /CIP document, with the exception of the wet weather protection project. This is a new project staff began after the wet weather events of last winter. The storm of December 31, 2005, which was no more than a 50 -year storm, resulted in water levels in Walnut Creek and Grayson Creek very close to the tops of the levees. Staff became concerned that these levees were not adequate to protect the treatment plant facility in events up to a 100 -year storm, for which they were supposed to have been designed. Therefore staff began an investigation to look at how best to protect the plant from major storm events in the 50 to 100 -year range where overtopping of the levees was possible. Staff will discuss some preliminary findings at the November 30, 2006 workshop. Collection System Program The major 2007 -08 projects planned for the collection system can be grouped into four categories, renovations to existing sewers, developer related services, the A -line phase 2A capacity project and the Alhambra Valley trunk sewer phase 2. Estimated expenditures are shown as follows. Category Annual expense % Collection System Program Renovation program $7,800,000 30% Developer services $1,050,000 5% A -line Phase 2A $11,800,000 45% Alhambra Valley Trunk $1,200,000 5% All others $3,650,000 15% Total $25,500,000 100% As you can see, the major drivers of the Collection System Program for 2007 -08 will be the renovation program and the A -line Phase 2A. The A -line project is a joint project with the City of Concord. Approximately $4 million of the project is for an intertie to the Concord pumping station, which will allow the abandonment of the station. This portion of the project will be funded 100% by the City of Concord. Of the remainder of the project, after the Concord flows enter the A -line, approximately 30% of the flows will be from Concord and therefore they will fund 30% of the remaining capital cost, for a reimbursement of $2,215,000. So, of the total $11,800,000 A -line Phase 2A cost to be expended in fiscal year 2007 -08, $6,215,000 or 53% will be reimbursed by Concord. The ongoing renovation program will take us to North Orinda, Walnut Creek, Danville and Martinez in 2007 -08. The renovation projects continue to be challenging, with many backyard easements and difficult field conditions. Impacts to the community are sometimes difficult to mitigate. Staff is doing an excellent job implementing these difficult projects. We are beginning to see some positive impacts. Sewer system overflows are trending downward. Staff believes this is due both to improved cleaning and to the renewal of problem sewers through the renovation program. An update on sewer system overflow trends will be provided at the November 30, 2006 workshop. General Improvements Program General improvements in fiscal year 2007 -08 will be modest and will include the traditional equipment budget, information technology budget and items associated with miscellaneous District facilities. The large budget Headquarters Office Building HVAC project should be complete before the start of the fiscal year. The construction of the new Collection Systems Operations Building is not expected until fiscal year 2008 -09. The design of the facilities and navigation of the City of Walnut Creek review process is expected to take most of the 2007 -08 fiscal year. Recycled Water Program The recycled water program will see a larger than usual expenditure in 2007 -08 associated with the A -line Phase 2A extension. As part of this project, a recycled water distribution line will be extended to serve 18 new customers in the Diamond Boulevard and Meridian Park Boulevard area of Concord. The estimated expenditures for this extension are $900,000, of which Concord will reimburse the District approximately 30% or $235,000. SUMMARY The proposed 2007 Ten Year Capital Improvement Plan includes baseline renewal and replacement projects of $260 million ($26 million per year) as well as $34 million in capacity and regulatory projects funded directly by rates and a potential $50 million in bond funded large projects. The analysis presented in this memo indicates with the use of bond funding for large projects, the spending of the accumulated balance in the Sewer Construction Fund to a minimum balance of $30 million, and an average increase in the capital component of the sewer service charge of less than $1 per residential unit equivalent connection over each of the next nine years, the proposed Ten Year Capital Plan can be funded. Therefore, staff recommends incorporating the recommended preliminary budgetary figures for the 2007 -08 fiscal year Capital Improvement Budget and 2007 Capital Improvement Plan in the ten year planning document that will be considered at the January 2007 Financial Planning Workshop.
