The impact of a detention area on the very small (8.1 acre) site
at Lesher would affect outdoor physical education programs.
We request that, because of the minor nature of the addition; the
availability of the storm drainage system in Stover and the
impact on programs on this small site; requirements for detention
be waived.
Please call me if you have any questions.

Dear Ted,
This letter responds to comments from Kathy Malers of Storm
Drainage made at the Conceptual Review meeting on January 25,
1993 for the Science Room Additions at Blevins, Boltz and Lesher
Junior Highs.
Blevins: the addition and walks are built entirely on areas
already paved and do not increase run-off.
Boltz: the addition and walks, minus existing walks and paving
eliminated, add 1,620 square feet of hard surface to this 28.02
acre site (0.13%).
Roof drainage from the addition (3,710 square feet) plus
capturing roof drainage from an existing 8,200 square feet of
roof area currently discharging on grade, run to a drywell system
with a capacity of 265 cubic feet of water, not considering
percolation.
We believe the new drywell, which intercepts water from 8,200
square feet of existing roof, more than compensates for the
additional 1,620 square feet of hard surface created by the new
addition, and request that no detention requirements be imposed
at the Boltz site.
Lesher Junior High: the addition and walks add approximately
3,200 sauare feet of hard surface to this 8.1 acre site (0.9%).
Roof drainage from the addition (3,183 square feet) is planned to
tie into the existing system drainage system in Stover Street.
The existing building roofs currently drain into the storm
drainage system.
