BMP T5.13: Post -Construction Soil Quality and Depth Al
Design Guidelines
. Soil retention. Retain, in an undisturbed state, the duff layer and native topsoil to
the maximum extent practicable. In any areas requiring grading remove and stock-
pile the duff layer and topsoil on site in a designated, controlled area, not adjacent
to public resources and critical areas, to be reapplied to other portions of the site
where feasible.
Soil quality. All areas subject to clearing and grading that have not been covered
by impervious surface, incorporated into a drainage facility or engineered as struc-
tural fill or slope shall, at project completion, demonstrate the following:
1. A topsoil layer with a minimum organic matter content of 10% dry weight in
planting beds, and 5% organic matter content in turf areas, and a pH from 6.0
to 8.0 or matching the pH of the undisturbed soil. The topsoil layer shall have
a minimum depth of eight inches except where tree roots limit the depth of
incorporation of amendments needed to meet the criteria. Subsoils below the
topsoil layer should be scarified at least 4 inches with some incorporation of
the upper material to avoid stratified layers, where feasible.
2. Mulch planting beds with 2 inches of organic material
3. Use compost and other materials that meet these organic content require-
ments:
a. The organic content for "pre -approved" amendment rates can be met
only using compost meeting the compost specification for BMP T7.30:
Bioretention Cells, Swales, and Planter Boxes (p.959), with the excep-
tion that the compost may have up to 35% biosolids or manure.
The compost must also have an organic matter content of 40% to 65%,
and a carbon to nitrogen ratio below 25:1.
The carbon to nitrogen ratio may be as high as 35:1 for plantings com-
posed entirely of plants native to the Puget Sound Lowlands region.
b. Calculated amendment rates may be met through use of composted
material meeting (a.) above; or other organic materials amended to
meet the carbon to nitrogen ratio requirements, and not exceeding the
contaminant limits identified in Table 220-B, Testing Parameters, in
WAC 173-350-220.

The resulting soil should be conducive to the type of vegetation to be established.
. Implementation Options: The soil quality design guidelines listed above can be
met by using one of the methods listed below:
1. Leave undisturbed native vegetation and soil, and protect from compaction
during construction.
2. Amend existing site topsoil or subsoil either at default "pre -approved" rates,
or at custom calculated rates based on tests of the soil and amendment.
3. Stockpile existing topsoil during grading, and replace it prior to planting.
Stockpiled topsoil must also be amended if needed to meet the organic mat-
ter or depth requirements, either at a default "pre -approved" rate or at a cus-
tom calculated rate.
4. Import topsoil mix of sufficient organic content and depth to meet the require-
ments.
More than one method may be used on different portions of the same site. Soil that
already meets the depth and organic matter quality standards, and is not com-
pacted, does not need to be amended.
Planning/Permittinglinspection/Verification Guidelines & Procedures
Local governments are encouraged to adopt guidelines and procedures similar to those
recommended in Guidelines and Resources For Implementing Soil Quality and Depth
BMP T5.13 in WDOE Stormwater Management Manual for Western Washington. This
document is available at: http://www.soilsforsalmon.org/pdf/Soil BMP Manual.pdf
Maintenance
Establish soil quality and depth toward the end of construction and once estab-
lished, protect from compaction, such as from large machinery use, and from
erosion.
Plant vegetation and mulch the amended soil area after installation.
Leave plant debris or its equivalent on the soil surface to replenish organic matter.
. Reduce and adjust, where possible, the use of irrigation, fertilizers, herbicides and
pesticides, rather than continuing to implement formerly established practices.
