Statement of Problem
Numerous drainage ~omplaints g I)~n received in the past ~ years for the area bound _,~_
by Sandy Lake Road on the south, Moore Road on the west, Parkway Boul6vard on the north, and ~amual
Boulevard on the east. Residents of Meedowridge Condominiums have entpefienced enu~ss~e storm nmoff
from the Lee Elementary School site through the southwest comer of their property. Both the r--~id~mts of
Towncreek H apatiments and the property owner to the south (Austin) have comp~-Imxl of heavy storm nmoff
overflows through these properties. Other area residents have complained of heavy street flooding on both
Moore Road and Samuel Boulevard.
Summa~ of Data
Site development plans for Meadowridge - Phase 1,/nd"ding drainage, v~re lm:ated. Pavin~
and drainage plnns for Moore Road and the eustem one-half of Samuel Boulevard were also located. The
Austin and Univest properties along Sandy Lake Road are undeveloped.
3. Annl~/s of Ex/sting Conditions
Based on interviews, field reconnaissance, and es/sting dr~inn~e plans, an analysis of the
existing conditions was made. The analysis indicates that although a underground storm drain connection was
available, the Lee Elementary School site drainage was allowed to flow o~rland into the ~
Condominiums. In addition, the school and its parking lot were drained reward ~amuel Boulevard, allhou~h
there are no storm sewer inlels in Samuel to handle this runofl~ Furthermore, Snmaul Boulevard is
coustruct~l with very fiat slopes just south of parkway Boulevard. Consequently, ~uHer cep~city in this area
is ve~ small.
The flooding of the Austin property has incrcused due to thc ur~ni~tion of file areas south
of Sandy I ~ke Road. Provisions for a portion of tl~ drainage were made in the s~orm sewer between
MeadowridRe and Towncreek II Apertmems. However, inlet facilities for the offsite drnlun~c we~ not
installed when the Towncreek II Apamnen~s were built but a wall was built ac~ss the flow 10ruth, thus
aggravating the problem. Flo~s arc diverted west and overtax the gutters and inlets in Moore Road.
4. Proposed Solutions
As shown on Figure VH-12, a 'Y' inlet and storm drain ~xamsion is proposed at the northwest
comer of the Lee Elementa~ School site. in addition, a storm sewer slmuld be eomuq~ted uloa~ ti~ nn~h
property linc of the school site, where two ten-foot inlets are proposed m reduce s~reet floodi~ in ~muel
Boulevard. As an interim solution to the Austin, Town Creek H almmnants and Moore Road flot~ng a
inlet could be connected to this same system. A permanent solution for this area would in. lye construction
of a ~:~-inch storm drain in either Moore Road or throu~ the Austin. site es this.~.~
interim, ditch improvements and a detention pond could be coamuctea on t~ A~un prepay, m
to the previously mentioned 'Y' inlet. Total esOm~ted cost of the ar-~,,-~ impro~man~ along the north side
of Lee Elementary School is $69,000. Total estimated cost of pefm~aent drainage lmprovemm~ts to the Moore
Road area are $249,000. interim measures to improve dlmin~ for tile AnMin pl~p~ ~R~ ~timRted to
$28,000, not including ditch and detention pond improvemen~ Cost of ussomant ~qulsition is not lm:led~.
