• A Stormwater Management Report prepared by H and H dated 7/10/25
• CLA has performed a review of the application documents and offer the following
comments: Soil Scientist Report:
• The second page of letter should clarify that the first flag series is 1 through 9.
• The letter should indicate that surrounding land use especially down slope of the
development.
• The letter should discuss the potential for impacts.
• The letter should indicate if there are any Natural Diversity Database concerns.

• The E&S sheet needs more detail. Will the bioretention basins be used as temporary
sediment traps? How will runoff be controlled as the road is being boxed out? Is all
excavation and fill to create the road and lots to take place at once?
• Show silt fence barrier for development of individual lots.
• Provide more substantial E&S barrier such as woodchip berms and silt fence or compost
tube and silt fence.
• Infiltration trench locations, if proposed needs to be called out on plans
• Call out the location and areas of places that will be vegetatively stabilized
• CLA notes that no direct wetland impacts are proposed.
