The length of the level spreader should be determined by the design storm inflow rate and type of landscape downstream:

* 1.4 m of level spreader length per every 0.01 m³/s of inflow for discharges to a [[vegetated filter strips|vegetated filter strip]], [[Bioretention| bioretention]], [[Swale| swale]] or grassed area;

* 1.4 m of level spreader length per every 0.01 m³/s of inflow when draining to a [[vegetated filter strips|vegetated filter strip]], [[Bioretention| bioretention]], [[Swale| swale]] or grassed area;

* 4.3 m of level spreader length per every 0.01 m³/s of inflow when the spreader discharges to a forested conservation area.

* 4.3 m of level spreader length per every 0.01 m³/s of inflow when draining to a forested conservation area.

* The minimum level spreader length is 4 m and the maximum is 40 m.

* The minimum level spreader length is 4 m and the maximum is 40 m.

* The level spreader lip should be concrete, wood or pre-fabricated metal.
