Engineering has reviewed the site plan (Major Amendment) and offers these review comments for Amendment
approval.
SDP2022-00022
1. General
a. WPO Plan approval is required prior to Major Amendment approval. Please submit WPO plan at
earliest convenience.
b. Note: If WPO proposes nutrient credit purchase, purchase is required prior to receiving a Grading
Permit.
2. C2.3: Label managed steep slopes.
3. C4.2: Recommend against P narrow curb radius at end of bus loop since tight radius concrete is prone to
damage and may present ongoing maintenance /repair issue.
4. Revise design that concentrates bus loop runoff at curb cuts (blue circles, below) to then flow across side
parking access before reaching SWM. Design favors icing at curb cuts /side parking access. Recommend
inlets /pipe conveyance to SWM to avoid ice -over of side parking access in freezing temperatures.
