Infiltration Characteristics, Performance, and Design of Storm Water Facilities

This report provides comments and suggestions related to the Washington State Department of Ecology's draft manual, entitled "Stormwater Management in Washington State." These comments and suggestions are focused on those sections of the draft manual that relate to infiltration facilities. Specific issues that are addressed include the following: consistency in analytical approaches for estimating surface runoff and infiltration; additional approaches for estimating infiltration rates using soil texture data; comparison of recommended infiltration rates with selected literature values; comparison of recommended infiltration rates with selected measurements; and field measurements for estimating infiltration rates.
