In civil engineering and stormwater management, a design storm refers to a specific rainfall event defined and described by the statistical likelihood of the event occurring in a given rainfall year. Design storms are used as a standard for designing and evaluating stormwater infrastructure. For example, local stormwater standards commonly call out the 1, 2, 5, 10, 50, and 100-year storm events and the water quality storm event for a given geography, each of which plays a role in the design and implementation of stormwater infrastructure.
Where are you buying structural backfill these days? Is what you need readily available, or are you looking outside your area and/or waiting an extended time for delivery? With available land space continuing to decrease, stormwater detention/retention is commonly being designed underground. The current construction boom and increasing detention volume requirements have made rock scarce and expensive in many parts of the country.
