SDC Calculations and Estimates

Residential SDC Calculations Commercial SDC Calculations

When are SDCs Calculated?

SDCs are assessed at the time of new development or redevelopment of a property to account for the increased demands placed on the sewer, water, and transportation systems. SDCs could be assessed for the following:

New residential or non-residential development occurs
There is a change of use in an existing development
Additional dwelling unit is created
Increase of floor space or living area
New connection(s) to the public wastewater system

Residential Calculations

How Residential SDCs are Calculated

Residential SDCs are calculated on new development and additions. Water, Sewer, Transportation, and Parks SDC fees are calculated on a tiered basis based on square footage. Development Services measures square footage for residential as follows - all habitable space including but not limited to features such as bathrooms, closets, storage areas, and landings are measured to determine the SDC tier assessed. An addition to an existing dwelling can incur additional SDCs when added square footage moves the dwelling into a different SDC tier.

Residential SDC Credits

SDC credits will be given for the previous permitted use of a property within the last 10 years. Credits are not transferable between SDC categories. For instance, Water SDC credits cannot be applied to Sewer SDC fees.

Credits are applied to the permit fees when the SDC calculations are assessed.

Special Assessment Areas

Southeast Expansion Area Supplemental Sewer SDC

The Southeast Area Pump Station Project (SEAP) was included in the City’s Capital Improvement Plan. The main goals of the Project were to increase overall sanitary sewer system capacity, eﬃciency, and connectivity for properties within the Southeast Expansion Area (SEA) and adjacent developments. The Project consists of a sewer pump station, sewer force main and associated gravity conveyance mains to provide sewer capacity for future urban levels of development in the SEA. As identified in the SEAP, this extended serviceability, and additional capacity will help promote development within the SEA and adjacent areas.

The SEAP also identified funding strategies including “evaluate and implement areawide funding tools (e.g. supplemental system development charges) needed to catalyze infrastructure development.” A 50/50 public/private funding split was among the funding packages presented in the SEAP. On May 1, 2024, Council provided direction to pursue a modiﬁed 50/50 funding split, as described in this methodology.

This methodology sets out recovery of 50% of adjusted project costs through a supplemental sewer SDC reimbursement applied to the limited geographic area which is served by the Project.

Commercial Calculations

How Commercial SDCs are calculated

SDCs are assessed at the time of new development because of the increased demands placed on the sewer, water, and transportation systems. When a permit is issued for a brand-new development, the SDC rate in the adopted fee schedule will be used to determine the SDCs owed. For transportation, the rate may reflect the full or phased-in rate, depending on the timing of when the development permit is issued. Another factor in determining the SDCs owed, will be the development context and type of use (i.e., reductions based on type or location of use, as noted in the adopted fee schedule).

Redevelopment to a different use category on the SDC fee schedule can incur additional SDC fees. If the use isn’t changing categories, no additional SDCs will be assessed upon that change of use. However, redeveloping to a more intense use that changes to a new category under the fee schedule, you would be charged for the difference.

Commercial SDC Credits

SDC credits will be given for the highest permitted use of a property within the last 10 years. Credits are not transferable between SDC categories. For instance, Water SDC credits cannot be applied to Sewer SDC fees.

Commercial SDC Estimates

Obtaining an SDC estimate through City staff is highly encouraged, as SDCs are not only determined using the fee schedule but are also based on any previous use of the site or other circumstances that could lead to higher or lower fees than what the customer expects. This estimate will be prepared by City staff and will also determine if any SDC credits are available on the particular development site and what SDC charges will be assessed based on the current SDC fee schedule.

SDCs Requiring Analysis

If a development doesn’t fall into a category in the SDC fee schedule, additional information will be required so that a case-by-case determination can be made. In addition, certain SDC categories or situations may require additional information to be submitted to calculate SDC charges, often in the form of an analysis.

Wet Use

If the use is defined as a “Wet” Industrial use, the SDC fee schedule bases the charge on gallons per day (GPD) of water use for both water and sewer SDCs. If this is the case, information indicating GPD must be provided to the City by the applicant. Staff will confirm the information submitted is accurate and then assess SDCs will be assessed. For more information click on the link for analysis below.

If transportation SDCs need to be assessed, a PM peak hour trip rate is needed so that the City can charge a per trip rate.

Irrigation

Irrigation uses that exceed ¼ acre and that are served by a meter that serves both the irrigation use and other (e.g., indoor) water uses require additional analysis. When other water uses serve buildings that are more than an incidental use (e.g., school or office buildings), the irrigation portion of the SDC will be determined based on the meter size that would be required if the irrigation space were served by a stand-alone meter. Applies to water SDCs only.

Irrigation meters 3” and above will be assessed based on an analysis of gallons per day (GDP). Information indicating GPD must be provided to the City by the applicant. Staff will confirm the information submitted is accurate and then assess SDCs will be assessed.

In addition, certain SDC categories or situations may require additional information to be submitted to calculate SDC charges, often in the form of an analysis. For a case-by-case determination contact development@bendoregon.gov.

Special Assessment Areas

Urban Rate

A 30% reduction in applicable transportation SDC for uses in areas identified on the Urban Rate Area map adopted by City Council in the Fee Resolution. To qualify, the development must be in one of these areas, at least three stories high, the first floor of developments with frontage on arterial, collector, or for developments in the Bend Central District, main streets as identified in BDC Chapter 2.7, must be “commercial ready” as defined in BDC Section 2.7.3245.A. 1., 2., and 3. Rate is not available for development that includes any auto-dependent or auto-oriented uses (as defined in the BDC) or for single-unit or middle housing residential uses. Multi-unit residential does qualify if the other criteria are met.

Medical Overlay

The Medical Overlay District as defined in BDC Chapter 2.7 Article IV. Transportation SDCs in this District are charged based on ITE 720 w/in or near the hospital campus rate.
