FINAL DRAINAGE REPORT
CREERSIDE AT THE LANDINGS
' INTRODUCTION
The purpose of this report is to document the results of a
' hydrologic and hydraulicanalysis of the site known as Creekside
at the Landings. The site is located in the area originally known
as Landings 4th.
1
This study area includes those lots of Creekside located
adjacent to Breakwater Court, Creekside Court, Breakwater Drive,
and Westshore Way. Part of Creekside is the area known as
Shoreline P.U.D. This area is to be replatted to reduce the
number of lots, and a separate report will be prepared when the
replat is submitted.
The site historically drains into Harmony Reservoir.
According to the Master Storm Drainage Report for the Landings
P.U.D. as prepared by Cornell Consulting Company, Harmony
Reservoir provides adequate detention. The Schematic' -Master
Drainage Plan shows the storm routing for the Landings Creekside
is in Area 1.
The study area is divided into two basins. Both basins drain into
the North Inlet of Harmony Reservoir.
