Additional pavement markings and traffic control devices should be added to ensure design circulation patterns are properly established.
The plans should be revised to detail the proposed surfacing for the playground area to determine impacts to site runoff.
Playground area fencing should be revised to indicate non-climbable.
Safety fencing should be provided for the drainage basin with a locking gate.
The plans shall be revised to remove all stormwater design from the landscaping plan sheet C601 and lighting plans sheet C601.
Additional plantings around the stormwater basin should be added and include daffodil bulb plantings.
As per 244-194(G)(1) all structures must be accessible by means of a driveway which shall be not less than 10 Feet wide and which shall have a center-line grade of not less than 0.5% and not greater than 10%. The exit driveway centerline grade exceeds 10%.
Provide a narrative (table, routing data, etc.) addressing the DEP requirement to assess "Current" and "Projected/Future" Rainfall Events.
Provide the results of an additional soil boring/test pit and permeability results in the area of the underground infiltration basin - only one (1) was provided.
The Hantush Spreadsheets in Appendix G indicate a Kh value greater than 5 × R (the standard in the Coastal Plain). Provide a narrative justifying the value used or resubmit the spreadsheet using 5R.
The detail labeled "Underground Basin- Plan View" on Sheet C801 shows the 12" Outlet Pipe as having a 12" diameter and an invert of 142.5, whereas it is shown on Sheet C-400 as having a diameter of 10" and an invert Elevation of 142.67.
The "invert out" elevation out of the underground infiltration basin is shown on Sheets C801 and C400 as being 8: higher than the "invert in" elevation. The applicant should clarify if there is an inner baffle wall/outlet control device proposed inside the basin that would impound stormwater prior to outflow occurring. If this is the case, a detail should be added to the plan.
Elevations for each storm event should be added to the "Underground basin - Section View" detail on Sheet C801.
All storm sewer piping should be specified at 15" diameter, minimum.
