PDF Garden City Area Plan - Horry County Government

EXISTING CONDITIONSThe topography of Garden City makes stormwater management achallenge. A number of areas in the community experience localizedflooding following significant rain events. Over the last five years,Engineering and Stormwater staff have worked to develop a set ofstandards and design criteria that now allow Horry County to beproactive in its approach to stormwater and flooding issues.The Horry County Stormwater Management and SedimentationControl Ordinance, which was passed in 2000, set the standards thatgovern all new development in the unincorporated portions of thecounty. Stormwater Management is responsible for the enforcement ofthe ordinance. The Horry County Stormwater Management DesignManual provides assistance to the professionals who are involved in thedesign and construction of adequate stormwater management facilitiesthat meet all the requirements imposed by Horry County Council.part6StormwaterThe new stormwater ordinance allows Stormwater Management to dealeffectively with stormwater issues that arise as new developmentoccurs in Horry County. Assuring that the appropriate stormwatersystem has been designed and built for a new development is one of themany jobs that are handled by Stormwater Management. Developmentthat occurred prior to the creation of current regulations was subject toless stringent requirements and many of these older developments haveexperienced problems with stormwater and flooding over the years.Stormwater Management is working aggressively to deal with theseproblems and has an active program for the cleaning and maintenanceof major and minor ditch outfalls. Where the problems are theresponsibility of a homeowners association (HOA) or a propertyowners association (POA), Stormwater Management can recommendthat the association contact a licensed engineer to assess the problemand offer the appropriate solution.Stormwater Projects in Garden City• Outfall problems around Indigo Creek• Drainage problems in the Jamestown and Jensen communities• A recently completed project adjacent to the Kings Grantsubdivision that has resolved flooding issues along Frontage Road• Calhoun Drive Drainage ProjectCurrent Activities in the Garden City AreaInlet Square Mall Area – Drainage problems have been ongoing inthe vicinity of Inlet Square Drive. This area is served by 24-inch outfallpipe running under Highway 17 Bypass and continuing to McDowellShortcut Road. Stormwater Management has studied the problem anddetermined that two specific issues need to be addressed. First, theoutfall running downstream to McDowell Shortcut is insufficientlysized and needs to be enlarged. Second, the outfall pipe under Highway17 Bypass is undersized and needs to be replaced with a larger pipe.Stormwater Management staff is working with affected propertyowners and the SCDOT to resolve a number of outstanding issues thatwill allow the appropriate fixes to be made to the outfall.Garden Lakes VillageDrainage and flooding problems have been ongoing forresidents of Garden Lakes Village.
