shifting sandsof older areas in accordance with MDE’snew policies would be anticipated togradually reduce impacts of stormwaterrunoff from these older areas. Newdevelopment done in accordance withcurrent MDE stormwater managementguidelines will probably not cause thesevere problems that older developmentdone prior to modern guidelines/requirements did. However, in spite ofthe strength of these MDE requirements,the long-term effectiveness of stormwatermanagement measures is yet to bedetermined. Additionally, it is likely thatcumulative effects of large-scale newurbanization will gradually impair surfaceand groundwaters since their pollutiongeneration rate is greater per acre.Recommendations• Implement WorcesterCounty’s Comprehensive Planrecommendations regardingimpervious surfaces.14• Initiate research projects to definesuccessful measures for preventingor restoring degraded habitat inbrackish and marine waters. Formore information, see Chapter 3—Management of the Coastal Bays &Watershed.Stormwater best managementpractices should be implementedin Ocean Cityof disturbance. Therefore, 99% of alldevelopment/redevelopment in the townmust incorporate some sort of BMP thattreats stormwater.The choices of BMPs in Ocean City arevery limited. Lot size and value are themain restrictions. Buildings are locatedsetback to setback, and after parking andlandscaping requirements and location ofutilities, stormwater management is thelast to be incorporated into the site plan.Another consideration in choosing BMPs isthe location of Ocean City. Ocean City isa flat barrier island with 100% urban landuse, and all of the storm drains empty intothe Coastal Bays, not the ocean. The oceanside of the island is very sandy; however,the bay side is man-made land, usingdredge material. Soil infiltration rates,A summer thundershower floods the Coastal Highwayin Ocean City. Sitting only a few feet above sea level,Ocean City floods frequently, especially when rainevents occur at high tide.Gail BlazerMaryland Department of NaturalResources (DNR) and MDE have developedstormwater management proceduresfor Ocean City. MDE requires waterquality volume treatment and DNRrequires proof of pollutant reductionand habitat enhancement. Therefore,best management practices (BMPs)must be utilized on new developmentand redevelopment projects to meetthe intent of both regulations. The MDEstormwater regulations start at lots 460 m2(5,000 ft2) in size and DNR’s regulationsaffect anything over 23 m2 (250 ft2)A stormdrain lies under nine inches of water indowntown Ocean City during a nor’easter storm inFebruary, 1998.Dave Wilson112
