HomeMy WebLinkAboutProject DescriptionThe project consists of the redevelopment of approximately 13.84 acres into a mixed-use
subdivision as well as road and utility infrastructure. The majority of the site will drain to the
existing creek north of the site, while the remainder of the site will drain to the existing ditch
along smokey row road. Water quality will be provided by a combination of underground
isolator rows as well as mechanical separators. Per the City of Carmel’s Stormwater Technical
Standards, the allowable runoff from the post developed site will be limited to 0.10 cfs/acre for
the 10-year storm and 0.30 cfs/acre for the 100-year storm. Due to topographic constraints, it was
not possible for the entire proposed site to be collected and discharged to the proposed detention
basins. These areas (1.17 total acres) were accounted for in the detention volume calculations but
were removed from the allowable release rates determined by the Carmel stormwater standards.
Therefore, a total of 12.67 acres was used to determine the allowable discharge rates. The total
volume of storage required & provided to meet city standards is 4.49 ac-ft. Proposed 8”, 6” and
12” watermain is proposed throughout the site and will connect to a newly constructed water
main along Smoky Row. Water laterals and meters are proposed to serve all the proposed lots
and is equipped with hydrants to meet all fire safety. 8” sanitary main is also proposed
throughout the site and connects to a newly constructed sanitary main along Smoky Row as well
as laterals and cleanouts to serve all proposed lots.
