RE: Glendale Road Cluster Development
Stormwater Management System Certification
Dear Doug:
Sarah’s Pet Services, Inc. was issued a stormwater permit for the Waggin’ Trails Dog Park & Cluster Development
project on Glendale Road (Map 49, Lot 4) on 10/12/2017. Subsequently, the owner sold property associated
with a proposed cluster development (Map 49, Lots 60, 61, and 62 on the current tax map) to a separate entity.
That entity, MS Homes, LLC, has now completed construction on three single family houses on the above-listed
lots.
Berkshire Design is the engineer of record for the above-referenced project. Personnel from Berkshire Design
were on site during critical periods to observe the materials and construction of the stormwater management
facilities. Additionally, as-built conditions of certain critical components of the stormwater system were
surveyed by Berkshire Design after completion. The project was built in general conformance with the approved
plans. Berkshire Design has assessed any minor discrepancies and found that they have not impacted the ability
of the system to meet the goals and requirements of the approved system.
Based on the site survey, we find that impervious area in the as-built condition is approximately 940 sq. ft. less
than the impervious area shown on the approved permit plans (17,040 sq. ft. as-built vs. 17,980 sq. ft.
approved).
Based upon the information listed above, it is my professional opinion that the stormwater facilities will function
as designed.
This certification is limited to the cluster development on Lots 60, 61, and 62. Other portions of the Waggin’
Trails site remain un-developed and will require stormwater management features to be constructed in the
future to support proposed development on the remaining property.
Sincerely,
Berkshire Design Group
