GI#22 Revised 5/25/2018
117 trees were planted in Liney Ditch Park which is in the Waterfront
South neighborhood. This neighborhood experiences the worst air
quality in Camden, with many industrial neighbors contributing
pollution and unpleasant odors. The deciduous and evergreen trees
planted absorb odors and stormwater, improve air quality, provide
shade, beautify Liney Ditch Park, and provide wildlife habitat. Trees
and shrubs clean the air of micro-particles of all sizes by
interception. Interception of air pollutants may be 20 times higher in
treed or forested areas than non-forested cropped or barren lands. Shelterbelts are vegetation
systems that use trees arranged in row or group configurations to redirect wind and reduce wind
speeds, thereby modifying environmental conditions within the upwind and downwind sheltered
zones. Trees are highly effective at physically intercepting dusts, gases and microbial particles that
are carried in the wind. Shelterbelts have the ability to reduce odor concentrations significantly by
several different means. On windy days a shelterbelt will create turbulence forcing the odorous air to
mix with clean air at higher elevations. Shelterbelts also encourage settling of dust and particulates
by reducing wind speeds. These particulates often carry odors. Another mechanism for odor control
is the physical interception of dust and particulates. As the odorous air moves through the shelterbelt
the odorous particles collect on leaf surfaces thus reducing the odor. The last potential means by
which shelterbelts control odor is through adsorption of the odorous material on the foliage and the
subsequent breakdown of this material via microbial activity. Each tree captures approximately 2,000
gallons of stormwater per year and the trees in the park now divert an additional 234,000 gallons of
stormwater each year from the sewer system. This project captures 117,000 gallons of stormwater
per year. This project was completed in October 2013.
