Re: Central Camano Water Systems Cooperation Study - Report Appendix (Capital Facilities Replacement Review)

Dear Camano Cooperative Members:

Please find enclosed the DRAFT Capital Facilities Replacement Review for your water system. The purpose of analyses such as this is to use available information to estimate both the total cost, and the annual contribution to the eventual replacement, of all water system components.

I have prepared the analysis based on the records available to me at this time. One reason for this initial draft is to seek refining data (e.g. for Camano Cooperative, the age of the Indian Beach pressure reducing valve). Once the data is refined, the final report can be a very useful tool for the Board of Directors in guiding future decisions relative to assessments for the replacement of the water system’s facilities (I’ve discussed this further below).

There is one caution that I always make when preparing these analyses, that is, we should be wary of over-refinement. There is no doubt that there could be much fine-tuning on the margins. For example, should the useful life of the storage tank be 40 years, as I have used, or should it be 50 years? Or, should interest / inflation be included in the calculations? Communities invariably determine, even after many tweaks, that the required cost per household per year (as reflected in Column K) is still very high. The lesson, therefore, is not whether the Co-op’s cost per household per year should be $1,065.27, or $900, or $1,200, but that the replacement cost of the water systems capital facilities is high and should be addressed to the best ability of the Association.

If community members would like to further discuss the results of this review, I would be happy to answer any questions that may arise. As possible, it would be very helpful if you could forward to me any updates or corrections that you may have by Monday, April 11, 2016.

The notes below discuss the columns in the attached table.

As of April 11, 2016, there was no indication from Camano Cooperative Water and Power Co. that changes to the Capital Facilities Plan are necessary.

of 4


Column A

This column reflects a summary of the water system components. Water system component sizes, capacities, age, etc. have been based upon record information and documents. Please review this column and if you find incorrect information, please note it.

Column B

This is an estimate of the replacement cost (construction only) for the various water system components. For the most part, it is based on the budget cost information sheets enclosed herein. For instance, for the 100 square foot Conklin pumphouse, it is prudent to budget $670 per square foot for a new pumphouse. This is an all‐inclusive construction cost and takes into account the building, piping, pumps, electrical, control system, etc. The Column B value therefore for the 100 square foot pumphouse is (100 x $670/sq. ft.) = $67,000.

Column C

Recent experience has shown that other (non‐construction) costs for water system projects in Island County can add as much as 35% – 40% on top of construction costs. For this cost analysis, an additional 35% has been used. These additional costs can include engineering, construction management, archaeological / environmental review and mitigation, permitting, attorney’s fees and contingencies. This column reflects the total estimated component replacement costs.

Column D

The review year for this report is 2016.

Column E

Based on available information, the installation year for the noted component is reflected in this column. In some cases, I have estimated the installation year of a component. Please review this column. If your information differs from that included herein, please note this also. Column F

Column D minus Column E.

Column G

The expected life of a component is based upon the table enclosed in this report (Enclosure E-1). This Expected Useful Life table is a summary of fourteen data sources which evaluated

of 4


the expected life of water system components. In the right hand column of the table, I have suggested an anticipated useful life for the various components. Column H

Column H is the arithmetic difference between the component age and the expected life. As noted herein, the result may not necessarily be meaningful for this cost review. For example, for the Monticello Storage Tank, the years remaining to replacement is zero. Clearly, the tank is functioning, and will continue to function for some time into the future.

Column I

This column allows the reviewer to use a more reasonable anticipated remaining life value for the various components. Again, considering the Monticello storage tank, I have estimated a remaining life of ten years for this component. The values placed within this column will be based upon the reviewer’s knowledge of the condition of the various water system facilities.

Column J

The current number of households (aka, Equivalent Residential Units) connected to the water system.

Column K

This is the amount that each household would need to contribute toward a Capital Facilities Replacement Fund (“Replacement Fund”) each year to provide their share of the cost for the noted component. For example, for the Monticello storage tank, each household would need to contribute $22.19 per year for the replacement of this component.

Column L

The noted support documents for your report are included herein, and the location reflected in this column.

Column M Miscellaneous notes, including cost information not reflected elsewhere in the report.

Discussion

Looking at the bottom of Column K, the total required contribution per household of $1,065.27 per year to a Replacement Fund is much more than is typically acceptable to the average homeowner. With the exception of a new water system, I am not aware of any similar analysis which did not result in an uncomfortably high required contribution to a Replacement Fund. Most communities, therefore, do not find it feasible to contribute to a Replacement

of 4


Fund at the level provided in these analyses.

Having said that, however, one should not cast aside the results of this analysis as it does a reasonably good job of providing a long‐term replacement cost of a community’s water system. Most communities of which I am aware, have utilized the results of these analyses to increase (or to initiate) contributions to a Replacement Fund. If a given component were to fail and require replacement before there is sufficient money in the Fund, a water system may elect to finance these capital replacements through one of a number of loan programs available.

Sincerely,

Cane Engineering
