6.2. Detention and Outlet Design
Without a public storm system on or adjacent to the subject parce
elevation available to daylight a pipe, discharge from the proposed
is proposed to be facilitated entirely by infiltration into the on-site
outlet structure proposed as part of the project. Alternatively, the
by the percolation rate of the on-site soils (estimated by the proje
to be between two [2] and five [5] minutes per inch) and the appr
foot footprint of the 100-year detention volume. This translates to
volume of approximately 402 cubic feet. Calculations for the pond
detention storage volume can be found in Appendix C.
The soils report calls
out as stated that the
perc rate is between
2 and 5 inches per
minute. It started at
2 and ended at 5.

There are no existing or proposed drainage easements or tracts associated with this
project.
6.4. Off-Site Drainage Facilities
All runoff generated on this site is tributary to a proposed, on-site detention pond at the
low point of the site. Since the pond is being sized to capture the estimated 100-year flow
rate tributary to it and infiltrate the entirety of the volume, it is anticipated that there will
be a reduction in runoff leaving the site; thereby improving the downstream condition.
There are no off-site drainage facilities anticipated to be negatively-impacted by the
proposed redevelopment.
6.5. Maintenance
Maintenance associated with the storm water infrastructure of the project generally
requires that built-up sediment be removed from the open channels. The bioretention and
detention pond shall be inspected to ensure water continues to flow freely into it. Periodic
removal of sediments and plans may be necessary when clogging reduces infiltration
capacity to unacceptable levels. For more information, refer to Table 2 below which is
Table 8.12 within the URMP.

design is intended to operate.
