Work also included installation of concrete apron with new grading and integral trench drain to divert stormwater from vehicle maintenance bay drains, regrading of the MEP lot adjacent to new concrete apron at the rear of AMSA to eliminate standing stormwater, and site surveying activities.
The new stormwater features and site grading were completed in order to mitigate an existing issue with stormwater ponding occurring near the northeast corner of the U.S. Army 99th’s PA179 Wilkes-Barre Reserve Center building. CEG will install an estimated 258 Linear Feet (LF) of reinforced concrete pipe, an inlet connected to a trench drain and roof drains, an energy dissipating outlet structure. An 18’x10’x2’ bed with a 2’x2’ yard drain buried two feet deep was proposed to manage the increase in stormwater runoff resulting from the new impervious surface associated with the new apron.
