Section 3: Site Design

1. This facility will operate two separate streams of waste material. One compost stream will be
comprised exclusively of leaf debris. The City of Gastonia collects leaf debris from
throughout its jurisdiction from October through March. This material is stockpiled on the
southern bed. This leaf material will be stockpiled until ground. Once the leaf material is
ground it will be assembled into double windrows on the lower bed. These windrows will be
constructed approximately 15 feet high and 25 feet wide at the base. The second waste stream
will consist of yard debris including tree trunks, limbs and branches, shrubbery cuttings, and
grass clippings. These materials will be stored on the upper bed until grinding. Once the yard
waste is ground it will be assembled into double windrows on the upper bed. These windrows
will be constructed approximately 15 feet high and 25 feet wide at the base.
2. This facility accepts approximately 232 tons of bulk yard waste per month and 3600 tons of
leaf debris from October 1st until March 31st.
3. This facility is capable of receiving and holding 38,000 CY of bulk yard waste, and 49,000 CY
of leaf debris. This will be a total of 87,000 cubic yards of un-processed material. This facility
is capable of holding 38,000 CY of finished mulch and 11,900 CY of composted leaf debris.
This will be a total of 49,900 cubic yards of processed material. This will be a grand total of
136,900 cubic yards of material.
4. Through 10.
Both streams of bulk material are stored in bulk form until semi-annual batch grinding.
Grinding is performed on all bulk-stored material in August and again for yard material in
February. Ground material will be windrowed as described and tested prior to distribution to
ensure successful composting. Distribution is currently scheduled for two cycles annually;
