Mitigation Plan checklist for plan reviewers
17 Feb 2014 (Use the latest checklist from the Team Services engineering forms site)
A mitigation plan is a document required by County Code Chapter 17,the Water Protection Ordinance
which illustrates stream buffer disturbance and the measures proposed to alleviate or compensate for it.
Reference key;
[Square Brackets] are County Code references, {Curved Brackets} are policy references,and(regular
parenthesis)are explanatory. Links to reference documents are provided where possible.
Title information: (applicable to any type of plan)
1/ Project title. Titles should be appropriate. It should be a mitigation plan,not a
stormwater plan, or erosion control plan, etc. Neal +0 5;1�

✓ existing topography(as shown on other final plans in process if applicable)
X WPO buffer limits; 100' from stream or wetland bank, 200' from reservoirs, or
floodplain limit if greater [17-317]
✓ floodplain limits, including 100yr flood limits for any channel with a drainage area of
50+acres [18-32.6.2d, 18-30.3]
✓ all existing easements (access, drainage, sight, sanitary easements, etc.)with deed book
references, locations and dimensions [18-32.6.2]

would typically be;

x_ maintenance narrative and schedule on plan,including a completion date.
fvf0, areas restored or replanted for mitigation must be protected in easements or by
maintenance agreements if they are not in a buffer. (This is a rarity, as all planting should be
/buffer restoration or reclamation. Noted exceptions are TJSWCD easement areas.)
�/ all concentrated discharges treated or extended to adequate channels to preserve buffers.
