Subject: Stillwater H.S. Stadium -- draina issues
Kris:
Here are a few questions/issues |have after reviewing the drainage calculations and VBWD correspondences from Jay
Pomeroy of Anderson-Johnson Assoc
w
The drainage calculations and area map provided cover the home bleachers side only (those areas draining to the
proposed infiltration trenches and infiltration basin. Proposed drainage for the visitor bleachers and other paved
surfaces/pathway around the north/northeast side ofthe field will create additional storm water runoff, but Jay
Pomeroy indicated that the VBWD was o.k. with the additional runoff being generated from these areas since they
drain east to existing grass/field areas (and the actual number increases are relatively small).

a school otormsewer that serves only the football �eld�r@ckarea, and is not owned/nmaint@inedby the CitV.
Regardless this a1orrmsewer should be relocated around the proposed bleachers to avoid potential futu ^
maintenance issues. (The larger 36" storm sewer that runs east-west approximately under the northerly goal line iaa
trunk storm sewer that io owned and maintained by the Oity). .
