Stormwater is generated from water that falls from the sky, including rain, hail, and snow.

In a natural, undeveloped landscape, most stormwater soaks into the ground to be stored or filtered before it reaches natural waterways. In a city, most stormwater falls onto impervious surfaces (surfaces that do not absorb water) such as roads, sidewalks, rooftops, or parking lots, and it is not soaked up by the ground. This water flows across these surfaces as runoff.

Most stormwater flows from private property to a stormwater grate in the street where it drops into a pipe and is carried, untreated, to the nearest waterway. The network of stormwater pipes is completely separate from the sanitary sewer system. Maintaining this pipe network is challenging.

As runoff flows across the ground, it picks up pollutants that you can see (debris, dirt, and grease) and others that can’t be seen (fertilizers and detergents).

In most cases, everything that enters a stormwater system is carried untreated into water that we use for swimming, fishing, and drinking. Untreated polluted water has a direct impact on our waterwaysYou can do a lot to keep our waterways clean.

Runoff can also cause erosion and sedimentation by sweeping away and displacing soil. It can cause localized flooding when storm drains take on too much water at once. This video from another community shows flooding causing a stormwater culvert to fail.

Albany launched a monthly stormwater service charge in 2017 for single-family residences and all other properties with impervious surfaces.

The City Council chose to start small and grow the program slowly over time. Learn how rates are calculated and forecast.

The Oregon Department of Environmental Quality (DEQ) recently issued a statewide general permit applicable to small communities that addresses pollution in stormwater and governs discharges of stormwater. Compliance is mandatory. However, before the permit went into effect, Albany and five other Oregon communities filed lawsuits against DEQ challenging the scope of the permit. The lawsuits are pending. Learn more about stormwater regulatory requirements.

Albany’s stormwater rate structure has two components: a base charge and an impervious surface charge. The base charge is the same for all accounts; everyone pays the same charge to recover the costs of billing and general stormwater system use. The impervious surface charge is based on the amount of impervious surface (roofs, pavement and gravel) on each property. A general description of how rates are calculated follow and more can be found in the stormwater rate resolution (Resolution 6676 for 2018 rates and Resolution 6713 for 2019 rates).

Single-Family Residential (SFR) Bill Calculation

For single-family residential properties, the impervious surface charge is the same for all customers and is based on the typical amount of impervious surface on single-family residential properties (Equivalent Residential Unit or ERU). Rates for single-family residential customers are also tiered where those customers with smaller structures pay slightly less and those with larger structures pay slightly more. In 2018, most single-family customers are in the middle tier and pay $7.08 per month. 

  Base Charge $5.03
+ Impervious Surface Charge ($2.05/ERU x 1 ERU) $2.05
= Total Stormwater Bill $7.08

Non-Single Family Residential (NSFR) Bill Calculation

For other properties (businesses, apartment complexes, government properties, etc.), the impervious surface charge is based on the number of Equivalent Residential Units (ERUs) of impervious surface present on the property. The number of ERUs is determined by calculating the amount of impervious surface on the property and dividing it by the typical impervious area found on residential properties in Albany (3,200 square feet). The number of ERUs is multiplied by the impervious surface rate per ERU. 

This illustration shows an NSFR bill calculation using 2018 rates for a property that has 26,136 square feet of impervious surface:

nsfr illustration

  26,136 sq. ft. of impervious surface
÷ 3,200 sq. ft. / ERU*
= 8.17 ERUs
  Impervious Surface Charge:
($2.05/ERU x 8.17 ERUs)
+ Base Charge $5.03
= Total Stormwater Bill $21.78

Non-single family residential customers can also pursue specific credits in order to help reduce their bill. NSFR credits are possible for approved on-site structural stormwater controls that either reduce stormwater volume or improve stormwater quality. Examples of structural stormwater controls include bio-retention, vegetated filtration, infiltration, or media filter facilities. For new development or redevelopment projects to qualify for the credit, the installed BMP would have to exceed what is normally required as part of the development. All facilities would require prior approval by the City, and the maximum credit available will be 25% of the impervious surface charge.

Stormwater Rate Forecast

Albany’s stormwater utility was created in 2017.  Stormwater fee adjustments in 2018 were limited to inflation (5%, $0.34 increase for average single-family residential (SFR) bill); adjustments in 2019 will also be limited to inflation (5%, $0.35 increase for average SFR bill).  Adjusting for inflation, however, doesn’t address the growing backlog of unfunded system needs.  Because of that, the City Council intends to incrementally raise rates beyond what’s required for inflation beginning in the spring of 2020.

Every year, the Council evaluates system needs, revenues, expenditures, and potential rate adjustments; sets goals; and considers options for meeting them over time.  Each year’s evaluation includes a 5-year forecast of anticipated rate adjustments.  The Council recently set a goal of generating $1.4 million more (today’s dollars) in annual stormwater rate revenue by 2024.  This revenue will be needed for regulatory compliance and to free up street funds that have been used to build stormwater improvements:

  • Regulatory Compliance ($300,000 to $1,000,000 per year) – The Oregon Department of Environmental Quality (DEQ) is expected to impose new stormwater requirements on Albany and other cities our size starting in January 2019. Complying with the proposed regulations could cost Albany rate payers an additional $1,000,000 per year. Albany staff believes the proposed requirements are unreasonable and we are working with various partners to communicate that to DEQ. We estimate complying with reasonable requirements would cost an additional $300,000 per year. Compliance with DEQ regulations is mandatory.
  • Stormwater Improvements with Street Projects ($400,000 per year) - Albany staff estimate that approximately $400,000 in street funds is used every year to build stormwater improvements associated with street projects.  Stormwater work must be done to meet regulatory requirements for stormwater quality and to replace undersized or aging pipes before streets are paved to avoid cutting through new pavement for pipe work. This is a justifiable expense, but the condition of Albany’s streets is declining, and those funds are needed for street maintenance.  

The additional $1.4 million will address some unfunded needs in the stormwater system, but others remain, and they are substantial.  

  • Replacing Failing Pipes ($20,000,000 - $40,000,000) – Significant portions of Albany’s piped stormwater systems are failing. With only 50 percent of the system inspected, eight miles of pipe have been identified as failed or anticipated to fail within the next 10 years. Another mile of pipe needs significant maintenance and repair because roots have broken through it. Fixing those nine miles of pipe would cost an estimated $20,000,000. If the remaining 50 percent of the system is similar, the cost goes up to $40,000,000. If the work isn’t done, Albany streets will flood more often, sink holes will form and property will be damaged. A funding source for this work has not been identified. If costs for regulatory compliance are less than anticipated, a portion of the $1.4 million in additional revenue will be used to replace failing pipes.
  • Capacity Increasing Projects (Costs TBD) – Some of Albany’s stormwater pipes are too small to handle the runoff from storms. The City is working on a stormwater master plan that will identify these pipes and determine how big they should be. The master plan will also identify the cost to install larger pipes. No funding is currently available for this pipe work.

To raise the $1.4 million, City staff estimates that stormwater rates will need to go up 17% per year, beginning in 2020. However, the City Council will consider actual adjustments annually, based on current revenue and expenditure information. Regulatory requirements alone could significantly impact planned rate adjustments.

If implemented as forecast, in 2024 an average SFR stormwater bill would be $16.30 per month. This table shows average monthly stormwater bills for a range of Albany customers today and with forecast increases through 2024.

Q:  Why would I get charged for the rain that falls on my property?  I don’t have any control of whether it rains or not.

A: A stormwater utility is a means of fairly apportioning costs to properties in the City that use and/or benefit from the City’s stormwater system. Developed land creates stormwater runoff that the City must manage through inlets, pipes, ditches, and other facilities. The City incurs costs from basic operations and maintenance, replacing old infrastructure, and complying with state and federal regulatory requirements. No other source of funding is available to adequately cover these costs that result in many benefits for Albany residents such as minimized street flooding, preventing disruption of service, lower cost repairs through proactive response vs. emergency response, improved riparian habitat, and cleaner waterways. 

Q:  Doesn’t stormwater go into the sewer pipes and get treated at the City’s sewer plant?

A: No. Albany has a separate stormwater system consisting of an estimated 135 miles of stormwater pipes and 70 miles of ditches that discharge to various waterways without treatment. In response to regulatory requirements, Albany has started to install some planters as natural stormwater treatment systems with road projects but most of Albany’s stormwater is discharged to waterways without treatment. 

Q:  Do other communities in Oregon charge for stormwater services?  What do they charge?

A: Yes, approximately 40 other Oregon communities charge a separate fee for stormwater services. For a single family residential home owner in 2018, the service charges ranged from $1.00 per month in Sweet Home to $30.01 per month in Portland.

Q:  Can Albany choose not to comply with stormwater regulations imposed by the Federal EPA and Oregon DEQ?

A: If regulated entities do not comply with their stormwater permit requirements, EPA has the authority to impose penalties of up to $37,500 per violation per day and the Oregon DEQ can impose penalties of $25,000 per day per violation.  When Salt Lake County, Utah failed to develop, implement, and enforce a stormwater program as required in their stormwater permit, they were required to pay a civil penalty of $280,000 and to also fully comply with their permit requirements [Consent Decree in United States, et al. v. Salt Lake County, Utah (DOJ Case No. 90-5-1-1-10984)].

In addition, there is the possibility of third-party citizen lawsuits to require compliance.  If the citizen lawsuit is successful, the City would also be liable to pay the third party’s attorney’s fees.  In addition to civil penalties, there is the possibility of criminal prosecution if the violation was intentional.

Q:  My property doesn’t drain to the City’s stormwater system; why should I have to pay a stormwater fee?

A: Regardless of where a property drains, properties receive services from a properly managed stormwater system. Also, regulatory requirements are imposed on the city as a whole, not property-by-property. An example of a citywide service would be managing the stormwater system so the streets don’t flood. These systems have operations and maintenance costs, require periodic repair or replacements, and are subject to state and federal regulatory requirements. For more information, refer to the October 10, 2016. council memo.

Q: Does my stormwater bill come on the same bill as my sewer and water bill?

A: Yes, you receive one bill from the City for sewer, water, and stormwater. The charges are shown separately. 

Q:  Why is gravel considered an impervious surface for stormwater billing of non-single family parcels?

A:  From a technical perspective, gravel is defined as an impervious surface. In fact, the two primary methods used to estimate stormwater runoff, the Rational Method and the Natural Resources Conservation Service (NRCS) Technical Release No. 55 (TR-55) both define runoff coefficients for gravel surfaces that are very similar to paved surfaces. The Rational Method runoff coefficient for pavement is 0.90 compared to 0.85 for gravel. The TR-55 method runoff coefficient for pavement is 98 and the runoff coefficient for gravel is as high as 91.

This is a common practice among utility providers and is supported by technical calculations discussed above. The topic of gravel was discussed extensively at the October 10, 2016, council meeting.  For more information, refer to the October 10, 2016, council outreach memo.

flowAs more is learned about the impacts of urban runoff on waterways, more regulations are developed in an attempt to mitigate those impacts. These regulations are generally developed by the Environmental Protection Agency (EPA) under the Federal Clean Water Act. The State of Oregon, through the Oregon Department of Environmental Quality (DEQ), has accepted delegation from EPA, meaning they are responsible for implementing the federal regulations at the state level.

DEQ has adopted two stormwater regulations that affect Albany:

  • Willamette River Basin Total Maximum Daily Load (TMDL); and the
  • National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) Phase II.

DEQ has determined that the Willamette River does not meet water-quality standards for temperature, mercury, and bacteria. Since Albany discharges stormwater and treated wastewater to the Willamette River, we have been identified as a designated management agency (DMA) and are required to submit a TMDL implementation plan to help restore the water quality of the Willamette River. Many elements of the plan are related to stormwater. Albany is required to provide an updated plan every five years. Albany has been increasing its efforts towards TMDL compliance each year. 

2021-2022 TMDL Report

Now that Albany’s population exceeds 50,000, we must comply with NPDES MS4 Phase II requirements. DEQ manages NPDES compliance by a permit that requires a Stormwater Management Plan specific to Albany. The permit will specify many activities Albany must complete. Details of the permit and required plan are complex and generally fall under what federal rules call the six minimum control measures. Each is listed here with a link to the EPA fact sheet that describes it.

These fact sheets provide a general understanding of basic regulatory requirements for a community of Albany’s size. However, states that have accepted responsibility for implementing stormwater permits can impose more stringent requirements if they determine additional action is necessary to protect water quality. Based on review of DEQ’s draft permits, Albany believes DEQ will attempt to impose much more than the federally-identified minimum requirements. 

Albany staff and legal counsel are closely monitoring the DEQ permit development process.  Albany staff believes the proposed requirements are unreasonable and we are working with various partners to communicate that to DEQ.  Complying with the proposed regulations could cost Albany rate payers an additional $1,000,000 per year.  We estimate complying with reasonable requirements would cost an additional $300,000 per year.  

Regulated entities in Oregon that do not comply can be fined up to $37,500 per violation per day by EPA and $25,000 per violation per day by DEQ.  When Salt Lake County, Utah, recently failed to comply, they were fined $280,000 and still must fully comply with their permit requirements (DOJ Case No. 90-5-1-1-10984).  Third-party, citizen lawsuits can be filed to force compliance, and criminal prosecution is a possibility if the non-compliance is found to be intentional.
