View source for Construction: mulch placement

Wood mulch provides numerous functions to a bioretention practice including reducing soil erosion, filtration, protecting underlying soils from compaction, retaining moisture, and minimizing volunteer weed establishment. Communicate to contractor how to install and the mulch type in the plans and or specifications with notes, details, spot elevations, and other special features needed as per designed.

Equipment recommended for this task can be:
*Automated: Mulch blowers.
*Manual: Shovels, buckets, level rakes.<br>    

'''During installation:'''
#Ensure that mulch depth should be no greater than 75 mm to maintain oxygen supply to underlying soils. 
#Ensure that the top of the mulch meets the finish elevation as per design.<br>
