Standard Details

The following tables are links to design materials provided to encourage the use of structural low impact development strategies (rain gardens, planters, stormwater planters, swales, vegetated filter strips, porous pavements, soakage trenches, and drywells) into communities under 50,000 people through an OSU Extension outreach effort. Peer-reviewed by civil engineers and landscape architects in both the private and public sectors, these standard details could be the basis for developing both county/city and site-level stormwater management plans. These details are applicable to many different places, but information was developed specific to Western Oregon.

These details were created by Maria Cahill, of Green Girl LDS, and were funded as part of the SWAMP grant project. These details are licensed under a Creative Commons Attribution-ShareAlike 3.0 Unported License. Essentially, this means you may use the details in any way you like, including for commercial use, as long as you're willing to share any derivitive works that you create. You're supposed to give us credit, too, but that's not really necessary for the details we're supplying.

FOOTNOTES & DESIGN GUIDANCE TO AVOICE UIC RULE AUTHORIZATIONS

* Any facility that only treats runoff and does not reduce runoff volumes, duration, and peak flows impacts regional water quality. The water leaving the site may be treated, but additional runoff volumes erode downstream streambanks to reintroduce sediments and potential pollutants to the stream. A "Maybe" in this column means that volume reduction will occur but may not be in sufficient quantities to prevent streambank scouring. Click here to learn more about hydromodification from the EPA.
**Clay surface soils are acceptable, but some faster draining subsoils must be available for disposal.
*** A "Y" in this column means that no matter what, the facility is a UIC and must be rule authorized by the Oregon DEQ. An "N" in this column means that by itself, properly designed, this facility is not automatically a UIC. There are several things about the detail that could require review and/or rule authorization by the Oregon DEQ. See the table below.

Rule authorization or review by DEQ may be required: To avoid rule authorization by DEQ:
The facility serves as pretreatment for another UIC such as a drywell or soakage trench. Cannot be avoided. This facility will be considered a part of the UIC that must be rule authorized.
The approved disposal point injects stormwater underground in any kind of facility. Make sure the approved disposal point is to either a public storm pipe or directly to surface waters.
The constructed facility is deeper than it is wide. Make sure the dimensions of your facility are wider than they are deep. This includes the dimensions of any newly constructed parts of the facility such as the engineered planting soil.
See UIC Regulations in individual fact sheets for other conditions that may cause review. See UIC Regulations in individual fact sheets for other design guidance on avoiding inadvertantly creating UICs during design.
