==Overview==

Whilst we consider preparing our own set of STEP LID drawings, we are providing a quick reference list to drawing files from other Ontario and/or North American-based sources.

This page provides a collection of links to design standard and drawing examples from Ontario and/or North American-based sources.

If you want help in finding example details for an LID design, please email the [mailto:lid.pd.guide@gmail.com Wiki Guide email account] or use the comment box below.

Please see below a Profile view of an exfiltration system (or perforated pipe system) designed for use in the City of Barrie and used in conjunction with a typical storm sewer system. '''Note''': This cross section installment is 'not located within a WHPA', although the source document for this drawing showcases a similar design configuration, that is 'located within a WHPA', which is not supported by STEP.

==Infiltration Trenches, Chambers & Soakaways==

==Infiltration Trenches, Chambers & Soakaways==

Please see below a profile view of an infiltration chamber installed below a parking lot in a shopping centre development in Brampton, Ontario. The stormwater chamber system receives roof, road and parking lot runoff from a large drainage area that then drains to a receiving waterbody. The system was designed to provide temporary storage and controlled release of runoff from storms to minimize impacts to the receiving waterbody (elevated water temperatures, higher velocity flows, potential for elevated flood conditions, etc.). A 0.3m deep gravel bed with no outlet below a portion of the chamber area provides additional water storage in the event of a large or prolonged storm/rainfall event to provide better retention of sediment and the means to evaluate whether or not substantial infiltration occurs. Orifice flow restricting plates mounted on the outlets of each manhole cause stormwater to back up into the chambers and contributing storm sewers so that when flow into the manhole exceeds the maximum flow rate of the orifice plate, stormwater backs up into the chambers safely.
