November 15, 2011
City Hall, Room 209, 12:00 PM – 1:30 PM
1. Introductions of Task Force members and meeting attendees.
All members were present except for David E. Robinson, Curtis Bohlen, and John Cannell. Staff present
included: Doug Roncarati, Katherine Earley. Also in attendance were Conrad Welzel, Rich Niles, and
Andy Reese.
2. Review and approval of the SSWFTF minutes from October 18, 2011.
Gellerson motion, Brooks seconded, all in favor for accepting minutes.
3. Continued discussion of allocating combined sewer costs to the stormwater use charge and sewer
use charge.
Reese presented updated cost information for the allocation of combined sewer costs to stormwater
and illustrated the impacts to residential rate payers and other property types. Impacts to sewer and
stormwater fees were presented based on % CSO allocations of 0%, 25%, 50%, 75% and 100%.
The Task Force was asked to think about the allocation of CSO costs based on the numbers presented, as
well as their subjective “gut” reaction when they think about what is reasonable and fair. Reese
reminded the group that the allocation of CSO costs to a stormwater fee is not always an exact science
and arguments can be made either way. The following comments and key points were discussed:
Those most financially affected should receive some kind of rate relief. Capping the rate
increase is one method.
The analysis of impacted properties does not include all properties; only those with a water bill.
Therefore, all of the greatest impacted properties may not be captured. Ian Houseal noted that
the analysis was for approximately 15,000 parcels that matched water billing addresses to parcel
data. Therefore, the analysis does not include properties that do not receive a water bill or
those addresses that didn’t match between the two databases. For example, parcels may have
multiple billing addresses for water billing purposes and may have different nomenclature for
addresses.
Reese noted that approximately 1/3 of the total impervious area was accounted for in the
analysis used to develop the analysis of properties. Members questioned whether the analysis
was representative of the total properties and whether additional data work should be
performed to capture all impacted properties.
Properties in the Long Creek watershed were used by Veroneau as a sample impact to the
business community. Although comparing this program to the City’s is like comparing “apples to
oranges,” it is helpful to consider the financial impact to commercial properties. Properties in
the Long Creek watershed are charged $3,000/IA/year, which is roughly equivalent to
$14.25/2500 SF IA/month. This seemed to be manageable for most properties in the Long Creek
watershed. Based on a CSO allocation of 50% or greater, many properties will have an annual
bill greater than $7,300, which is almost $35/2500 SF IA/month. This cost is not sustainable for
most businesses and the CSO allocation should be closer to 25%.
Suslovic noted that some part of the CSO cost is stormwater; therefore, some part of the
program should be billed as stormwater.
Brooks noted that the residential sewer bill does not change significantly under the 0‐25% CSO
cost allocation scenario and this may be appealing to residents. Reese noted that under a 0‐25%
scenario, sewer bills for most rate payers go up only slightly and the residential stormwater fee
is about $8‐9 per month. From a psychological standpoint, the residential monthly cost is still in
the single digits and may seem “ok” to most people who are already used to slight increases in
utility fees.
A straw poll was taken to gauge what people were thinking for % CSO allocation. The question was
asked “How many people think the CSO allocation should be greater than 35%?” 3 members responded
in support and the following key points were made by various members:
From the perspective of residents, you could argue for an allocation of 40‐50% since the cost
goes down for residential properties as % allocation increases.
50% of the rate payers have carried most of the current share of CSO costs, so the CSO
allocation should stay closer to 50%. This seems more equitable.
One resident commented that the CSO allocation should be less than 25% to help businesses. In
the end, the impact to businesses is felt by residents since it increases the costs of local goods
and services.
It is difficult to isolate the cost allocations since you can provide the rationale for various
allocations. The Task Force seems to feel that the CSO cost allocation to stormwater is
somewhere between 20% and 50%.
Several members felt that more detailed analysis was needed for individual property impacts to
better determine the most appropriate CSO allocation. Members requested a revised “Dow
Jones” analysis using real properties and fewer numbers/types to focus on the most impacted
properties.
Preliminary Policy Recommendation #10: Portland should allocate somewhere between 20% and 50% of
the combined sewer overflow costs to the stormwater fee.
4. Continued discussion of capping credits
This item was tabled until the next meeting.
5. Review draft Task Force Recommendations
The Task Force reviewed the draft recommendations memo (dated 11/15/2011) during the meeting to
solicit comments and discuss any recommendations that required further review and consideration. In
general, the members of the Task Force agreed with the understanding and background information
provided in the memo. Additionally, the majority of the recommendations appeared to be consistent
with the information and recommendations discussed at previous meetings. However, the following
items were identified as requiring further review:
Item 14. Funding 50% of Portland’s combined sewer costs through a stormwater use charge and 50% of
Portland’s combined sewer costs through the sewer use charge.
Based on the results of the discussion for the allocation of combined sewer costs to a
stormwater fee, it appears that further review of the recommended allocation is needed and it
is in the range of 20% to 50%.
The group wants to review example properties and their impacts under various allocation
scenarios to consider the most appropriate and fair allocation of costs.
Item 21. The Task Force examined multiple rate structures for single family residential properties
including a single tier for residential properties, two tiers, multiple tiers and a fully variable rate. The
Task Force believes that Portland should use a simplified charge for single family residential properties
consisting of two to three tiers. Commercial properties should be roughly approximate to the residential
tiers set at 2500 square feet of impervious area.
Up to 4 units should be considered a residential property and residential properties that have
greater than 10,000 square feet of impervious area should be treated (billed) as commercial
properties.
This recommendation should be revised to: “Portland should use 2‐3 tiers for residential
properties”.
Item 24. The Task Force considered a credit system for properties to reduce their total stormwater use
charge in addition to properties being able to reduce their charge by reducing their impervious area. The
Task Force believes that credits should be tied to existing City development standards. Credits should be
capped at 50% on the grounds that the majority of stormwater costs are unavoidable and due to
maintenance and individual properties private action would not reduce the impact on the system above
that level.
The cap of credits at 50% requires further review based on the information discussed previously.
Some suggested that the cap be revisited during the next meeting based on the results of
individual property impacts from the pending CSO cost allocation scenarios and the ability of
affected property owners to seek a credit.
Item 27. The Task Force believes that to reduce the impact on those properties that are most impacted,
the total rate increase should be limited to some amount per year.
The limit on the amount of the rate increase should be more clearly defined based on the
pending CSO cost allocation scenarios and the most impacted properties.
6. Confirm date for next meeting: The next meeting is scheduled for December 13, 2011.

2. Review and approval of the SSWFTF minutes from September 20, 2011.
Gellerson motion, Veroneau seconded, all in favor of accepting the minutes.
3. Review Task Force Tentative Policy Recommendations
Reese provided an update of the tentative policy recommendations of the Task Force to date.
a. Portland should use an impervious area rate methodology and charge on the basis of
impervious area only.
b. Private efforts and investments to reduce the impact of development on parcels such as
the planned and engineered use of disconnection of impervious area should be
recognized and rewarded.
c. Portland should use a simplified charge for single family residential properties consisting
of two to three tiers.
d. Portland should exempt roads from the stormwater fee and should allocate those costs
across the rate base on the same basis as the rate methodology employed in
development of individual changes.
e. Portland should not exempt public property from the stormwater fee.
f. Portland should tie credits to existing design standards and develop a credit program
that is simple for property owners and the City.
g. Portland should offer credits for stormwater education if it makes sense from the
perspective of the current education program.
h. Portland should offer minimal or no credits to flat‐rate residential properties, but rather
focus on one‐time incentives for activities that support the City’s stormwater program
objectives.
i. Portland should cap credits at somewhere between 25%‐50% based on balancing
considerations of equity, impact of credits, and actual ability to reduce impacts.
4. Continued Discussion of Credits
Reese reviewed recommended credit types and the overall structure. He summarized a two part credit
methodology one for water quality and one for flood control. He stressed the overall concept that would
relate criteria to program cost to credit types and amounts.
Houseal stated that as with all the recommendations it is fair to revisit anyone of the recommendations.
The Credit recommendation would be highly dependent on the outcome of the cost allocation from
combined sewer to stormwater and the Task Force may want to revisit the credit allocation again after
discussing the combined sewer allocation question.
A Task Force member asked about the potential process for application. Houseal responded that the
proposed process would be development review to meet the standard and permits issued upon
completion. Application and receipt of credit based on demonstrated receipt of applicable permits. No
credit would be issued for waiver or exemptions from the standard.
Houseal described the potential impact of the credit approach on revenue reviewing potential credit
applicants based on known sites with credit‐qualifying structures and site that might qualify with
additional site improvements. The following facts were given:
Potentially 16 parcels currently qualifying for a credit: Worst case: no cap, 100% allocation:
$116,000 annual credit value. Mid Case: 50% cap, 50% allocation: $34,000 annual credit value
Additional 44 parcels that might qualify for a credit with additional site improvements. The cost
of these improvements are unknown: Worst case: no cap, 100% allocation: $124,000 annual
credit value. Mid Case: 50% cap, 50% allocation: $36,000 annual credit value.
Connolly asked about the impact on cost of tiering the credits. Houseal responded that the analysis that
was done was not able to determine which projects would get which credits, therefore it was assumed
the most costly credit effects (i.e. the worst case scenario and the Mid Case scenario. With a tiered
credit, the impact would be lesser still then either scenario.
Dillon asked if the costs represented in the analysis were city costs or builder costs. Reese responded
that the costs were the city costs.
Brooks stated that she was still only comfortable with the 0%‐25% credit amount.
With a growth rate of 2‐6 projects per year it is not anticipated that credit‐based revenue loss will be a
significant issue, though it was noted that all rate payers make up the difference in revenue given away
by credits. It was stressed that the City did not incur an immediate program cost reduction because
someone built a BMP or pond but that the City was investing in a better future over time.
Dillon asked if those required to construct BMPs or ponds should get a credit at all. Reese stated that
one theme in all the policy decisions was that similarly situated properties should be treated in a
consistent manner. No matter the reason a structure is built it should be treated the same way.
However this does not prohibit creating a separate standard for voluntary retrofit that was easier to
attain to encourage beneficiary stormwater detention or treatment.
A review of the incentive of a developer was done with Reese stating that BMPs cost in the range of
$100,000 per treated impervious acre. A spreadsheet model for the estimation of return on investment
was demonstrated showing that the credit capping and allocation decisions together determined the
break‐even cost for construction of BMPs on a site. The higher the fee the more credits mattered, and
the closer to a positive ROI a developer could come.
Gellerson asked if existing properties could be given a further incentive to reduce. Suslovic responded
that it was important to distinguish between credits and incentives and there was a need to balance
both with revenue loss. Suslovic stressed the importance of an incentive program.
5. Discussion of Allocating Combined Sewer Costs to the Stormwater Fee.
Reese presented the various aspects to consider when making a decision about allocation of CSO costs
to stormwater fee. The following seven topics were discussed: science and rate making, political and
affordability realities, impacts on property types, parcel analysis, the “shock and awe” of sudden change,
return on investment, distributions of costs between those that would be most negatively affected.
In current rate‐making practice there is no set way of doing this allocation. In fact, the vast majority of
municipalities do not allocate any CSO cost to stormwater – but this is based on the facts that they have
not begun to face high CSO costs, the wastewater organization does not have or control a stormwater
utility, or it was felt to be far easier just to call it a sewer cost rather than attempt to charge a
stormwater fee above national stormwater fee norms.
Thinking on the subject can sway from one extreme (“your stormwater is in my wastewater pipe and
you need to pay”) to another (“your wastewater is in my stormwater pipe and is causing pollution – you
need to pay.”). Also in the mix is potential stormwater program cost increases due to mandated
watershed planning. Reese stated that all these considerations probably mean a middle ground based
on some technical reasoning and practical assessment.
Some key points made include:
Allocation creates “winners and losers” in the sense that a large allocation of CSO cost to
stormwater would cause parcels with large impervious areas but little water use to have a
higher fee, and vice versa.
The existing sewer fee charge is $8.11 per HCF thus placing it in the middle of the range it would
end up at if allocation varied from 0% (around $11) to 100% (around $3.50). Thus an allocation
of over 50% to stormwater would actually reduce the current sewer rate. Does the City really
want to decrease people’s sewer rates?
Also, the stormwater program’s future costs for watershed planning and restoration are
currently unknown and not figured into this analysis. But they may be large. In addition, growing
stormwater infrastructure maintenance costs and anticipated future regulatory requirements
could also increase the cost of the program. So a shift to stormwater fee allocation would
reduce the perceived “headroom” for further increases in the future.
The stormwater rate curve (see figure) is relatively steep so it reacts more to an allocation, and
it starts at ZERO – that is, any stormwater fee is new, not an adjustment. Counterbalancing this
is the fact that while a residence would typically have one ERU it might have a number of HCF
charges – so an allocation to sewer, while relatively flat would have more units per month.
An analysis of 13,800 parcels for which both sewer and impervious area data was available
showed that a 50% allocation would impact properties the least in terms of the numbers of
winners and losers and average change from current sewer bill. For zero percent allocation
every parcel would experience a higher fee, though the average change would be less. For 50%
allocation far fewer parcels would experience an increase but there would be more with a
higher increase – that is, the burden of increased costs would fall on fewer parcels.
There are ways to reduce the impact on a few of those properties most effected through
capping the annual increase, extending the ramp up in their fees, or targeting incentives and
credits. All of these methods simply spread the program costs to others in the interim. It might
be, since analysis concentrated on five year averages that the program ramp up and the fee
ramp up would match to some extent.
As discussed by the Task Force, reasons for a lower allocation to stormwater included: the ability to
write off water use as a business expense and the ability to better control that use, and thus the fee, a
lower fee might be easier to pass, a lower stormwater fee compares better to national norms, it can be
argued that the overflow problem is a wastewater problem.
As discussed by the Task Force, reasons for a higher allocation to stormwater included: the value of the
higher fee in break even and return‐on‐investment analysis to better incentivize the use of green
infrastructure, the overflow problem could be argued to be a stormwater problem, fewer would face a
higher total cost and the ability to reduce the impact on the fewer most affected is attractive, we might
not go through all the trouble for a small stormwater allocation – not worth the pain of a new fee, the
concept that we start to get “winners” is attractive.
The average of the voting was 36.2% allocation to stormwater and the voting tally is:
12.5% ‐ 2 votes
25% ‐ 2 votes
37.5% ‐ 2 votes
50% ‐ 3 votes
60% ‐ 1 vote
It was agreed to reconsider the overall set of recommendations at the next meeting.
6. Discussion of public outreach plan.
The public outreach plan would be prepared by the December 7 for the Task Force to digest.
7. Discussion of the Date for Next Meeting.
The next meeting is scheduled for November 15, 2011. It was discussed that there would be no
December meeting, but reconvene in January to digest the public outreach plan based on some initial
public comment, but if a December meeting was needed the Task Force would meet then.

Different Parcels Impacted Differently
The more we allocate to stormwater the
worse it is for large paved lots with low water use
and vice-versa.

Losers in the Change
O% allocation means a lot more losers overall
50% allocation means many fewer but bigger losers

Should we help those most impacted?
If so, how?
• Capping the change per year
– i.e. <10% change/yr
• Extending the change for some years
– i.e. 5 year phase in
• Providing special incentives for credit
construction
– i.e. Grants to construct retrofit BMPs for
credits

Fiscal Impact and Capping
• City Side • Developer Side
• Current 16 parcels – BMP cost ≈ $100,000/acre
from Long Creek data
– Worst case: no cap, 100%
though some costs go
allocation: $116,000
much higher and Long
– Mid Case: 50% cap, 50% Creek is NOT downtown
allocation: $34,000 Portland
• Potential 44 parcels • ROI, NPV, BE Analyses
– Worst case: no cap, 100%
allocation: $124,000

Basic Rate Methodology
Preliminary Policy Recommendation #1:
Portland should use an impervious area rate
methodology as the basis for its charge.
Preliminary Policy Recommendation #2:
Private efforts and investments to reduce the
impacts of development on parcels such as
disconnection of impervious area should be
recognized and rewarded.
Residential Charges & Roads
Preliminary Policy Recommendation #3:
Portland should use a simplified charge for single family
residential charges consisting of two or three tiers of
charges if the housing stock analysis warrants more than
two tiers.
Preliminary Policy Recommendation #4:
Portland should not charge itself for its roads or, if
further study warrants it, charge a greatly reduced fee for
roadway surfaces.
Public Buildings
Preliminary Policy Recommendation #5:
Portland should charge a stormwater fee for public
buildings and property.
Credits
Preliminary Policy Recommendation #6: Portland should match
credits to design criteria and develop a program for administration of
the credit system that is simple for property owners and the City.
Preliminary Policy Recommendation #7: Portland should offer
credits for stormwater education and stormwater activities that
reduce the City’s maintenance burden if they make sense given
current programs.
Preliminary Policy Recommendation #8: Portland should offer one-
time incentives rather than credits to residential properties for
activities that support the City’s stormwater program objectives.
Preliminary Policy Recommendation #9: Portland should cap credits
somewhere between 25% and 50%, pending further evaluation of
revenue impacts for properties that may qualify.
Proposing: Two Credits
