Alternate rate and fee calculation

Parks

If you want us to use an alternate number of persons per dwelling unit for residential development, or resident equivalents for nonresidential development other than those used in the City’s Parks SDC Methodology Report, you must submit analyzed and certified documentation by a suitable and competent professional. Alternative systems development charge rate calculations must be based on analysis of occupancy of classes of structures, not on the intended occupancy of a particular new development. Use Alternative SDC Rate Request Form PSDC-6 and include it with the application.

Transportation

If you want us to use trip generation rates other than those used in the City’s Transportation SDC Ordinance and Rate Study, you must submit data certified by a professional traffic engineer. Use Request for Alternate Trip Generation Rate and SDC Calculation Form TSDC-3 to submit the data and attach it to the application. Institutional development (educational and medical campuses) may elect to base systems development charges on annual changes in trip generation. In this case, use Institutional Development of Special Trip Generation Rate and SDC Calculation Form TSDC-4.

Optional credit for providing qualified public improvements

Parks

To reduce the amount of your Parks systems development charge, you may donate property or improvements to certain qualified park facilities in the City of Portland. Use Request for Parks SDC Credit for Qualified Public Improvement, Form PSDC-7 to submit a request, and attach it to your Systems Development Charge Form.

Transportation

If you want to reduce the amount of your Transportation systems development charge, you may make improvements to specific transportation facilities in the City of Portland. Use Request for Credit for Qualified Public Improvement Form TSDC-5 to submit the data, and attach it to your Systems Development Charge Form.

Payment methods and timing

The City will give you a Notification of SDC Fees if you are required to pay any charges for your development.

For all systems development charges (SDCs)

  • Pay by cash, check, money order or credit card at the time the City issues a building permit.
  • Water SDCs are due when water services are purchased. Pay by check, money order or credit card.
  • Request a deferral of fee payment for 6, 9, or 12 months, depending on the project valuation, by signing a deferral contract. Interest shall accrue at the City’s interim rate during the deferral period and will be payable, along with the deferred amount, upon the end of the deferral period. There is a non-refundable $50.00 finance fee.*
  • Transfer SDC credits (contact respective bureaus for more information).
  • Request a loan contract by completing and signing an installment contract to pay the SDCs in monthly or bi-annual installments over 5, 10, or 20 years.
  • Special note: The City secures a loan or deferral by recording a lien on the benefited property. The lien remains in effect until the SDCs are paid in full. The City charges a non-refundable processing fee to cover the expense of setting up a loan or deferral. The installment contract must be signed by the property owner of record before the City authorizes a loan or deferral for the systems development charge.

If you need help with or have questions about your systems development charge, please call the appropriate department in the Contacts listed here. 

Portland Housing Bureau administers the SDC Exemption Program for affordable housing.

For more information, call Housing, visit the Housing website or email Housing for affordable housing exemption inquiries.

How SDCs are calculated 

Environmental Services 

Rates are for either the class and number of residential units or related to the size of a commercial project. Sanitary rates are calculated from equivalent dwelling units. Commercial equivalent dwelling units are estimated from the number and type of plumbing fixture units.

A table of the equivalencies for plumbing fixture units to equivalent dwelling units is available upon request from Environmental Services. Stormwater SDCs are based on the square feet of impervious area in the project and the number of trips the new property is expected to generate (using trip generation number used by Transportation).

Parks and Recreation

The rate is based on the type and size of building. Demolition credits may apply if demolition was within 36 months of the new permit intake date. SDCs apply to new construction, changes of use, and projects to expand existing use.

Transportation

The rate for each mode of transportation is based on the following:

  1. amount of money the City needs to collect over the next 10 years to increase the City’s transportation system to accommodate growth-related trips.
  2. The projected City growth in the next 10 years. The SDC rate is multiplied by the number of trips your proposed land use generates based on nationally compiled statistics.
  3. Additional Transportation SDC fees may be assessed on development that is located within certain “overlay” areas. To determine if a development is within an “overlay” area, or for further information, contact Transportation.

Water

The rate is based on the size of meter installed. Meter size is determined by the number of plumbing fixtures installed at the property. Fire lines are exempt from SDC fees.

System development charges rate changes 

City of Portland fees and charges are adjusted annually for inflation at the beginning of the fiscal year on July 1. City departments that charge SDCs may also change the rates at other times, but particularly at their SDC Review Cycle, which is different for each area of the City.

Reduce your systems development charges

Transportation and Parks each offer an optional alternate rate and fee calculation. Environmental Services Stormwater SDCs can be reduced by reducing the number of square feet of impervious area, such as with the use of vegetation or pervious pavement.

Systems development charges credits available

Credits for providing qualified public improvements are available. You must complete the correct credit form and attach it to the SDC Form. Credits include:

  • Environmental Services: gives credits for any equivalent dwelling units purchased with prior use of the property. Environmental Services credits follow a property and are not transferable.
  • Parks: allows credits if you convey qualified property or facilities to Parks and Recreation, subject to approval.
  • Transportation: allows credits if you participate in constructing certain types of street improvements, or change building use to one that reduces trips by more than 15%. Contact Transportation for an SDC list of capital projects and learn what projects qualify for a credit.
  • Water: gives credit for water services that are permanently removed. Credit is applied towards the SDC fee of a new metered service. Credits are not transferable.

Transfer, give or sell your SDC credits to someone else

Some credits may be transferred, given away or sold:

  • Parks: Some provisions are available to use credits on subsequent phases of the original development, or on other projects. Provisions are outlined in Parks SDC code.
  • Transportation: SDC Credit Transfers will be issued by the City, and are transferable to other persons and available for use on the same parcel, as credit for payment of Transportation SDCs only. Credits may only be used for development upon the same parcel from which the credit originated. Credits are good for a period of 10 years.
  • Environmental Services and Water do not transfer credits.

SDC exemptions available

  • Portland Housing: Contact Housing to inquire about the SDC Exemption Program for affordable housing or visit the Housing website.
  • Transportation: Remodels of buildings less than 3,000 sq. ft. with no change of occupancy are exempt. Buildings between 3,001 and 5,000 sq. ft. are assessed on a graded scale. Exemptions are available for qualifying affordable housing projects.
  • Environmental Services, Parks and Water: Exemptions are available for qualifying affordable housing and campus housing projects. Parks has additional exemptions outlined in City Code 17.13.060 (review the related webpage for more information).

Development Services and services development charges

SDCs are development-related fees, assessed to some projects. While the building permit is issued by Development Services, SDCs are associated with the impact the project will have on the need for additional development of specific portions of the City’s infrastructure. Other City departments are charged with the mission of planning and maintaining Portland’s streets, sidewalks, transit, water service, sanitary sewer system and parks. These services are partially funded through specific SDC fees.
