Criteria to Receive Credits for Minimizing Total Disturbed Area
To receive credit for protection of existing trees under a local regulation, the following criteria must be met:
❑ Area has not be subject to grading or movement of existing soils.
❑ Existing native vegetation are in a healthy condition as determined through a plant inventory and may not
be removed.
❑ Invasive vegetation may be removed.
❑ Pruning or other required maintenance of vegetation is permitted. Additional planting with native plants is
permitted.
❑ Area is protected by having the limits of disturbance clearly shown on all construction drawings and
delineated in the field.
❑ Area is located on the development project.
Designer/Reviewer Checklist for Minimize Total Disturbed Area
ITEM YES NO N/A NOTES
Do municipal requirements for open space and
related resource protection exist? Applied here?
Have related BMPs (Protect Sensitive Areas,
Natural Flow Pathways, Riparian Buffers, Clustering)
been applied?
Has Potential Development Area been defined?
Have infrastructure connections/constraints
been analyzed?
On site, have roads been aligned to fit topography,
to parallel contours and minimize cut/fill?
On areas previously cleared? With terracing?
Compatible with natural flow pathways?
On lots, have buildings been located to reduce
disturbance?
On lots, have maximum disturbance radii been
established and applied?
No disturbance areas shall be clearly delineated
on construction plans and flagged/fenced in field
Have no disturbance zones been assessed qualitatively
for invasive management needs?
