STORMWATER CONCEPT NARRATIVEPER THE ST. MARY'S COUNTY DEPARTMENT OF PUBLIC WORKS CHECKLIST, THE FOLLOWING ITEMS HAVE BEEN REVIEWEDAND INCORPORATED INTO THIS DESIGN:

· NATURAL RESOURCE PROTECTION AND ENHANCEMENT: SITE AND RESOURCE MAPPING HAS ESTABLISHED ABSENCE OFPARTICULAR RESOURCES IN NEED OF PROTECTION AND ENHANCEMENT. SITE SOILS ARE TO BE PROTECTED USINGEROSION AND SEDIMENT CONTROL MEASURES APPROVED BY THE ST. MARY'S COUNTY SOIL CONSERVATION DISTRICT.

· MAINTENANCE OF NATURAL FLOW PATTERNS: THE EXISTING PROPERTY SHEET FLOWS ACROSS THE SITE IN A PRIMARYWEST/EAST DIRECTION. THIS PLAN PROPOSES TO MAINTAIN THOSE EXISTING PATTERNS, AS WELL AS PROVIDELOCALIZED TREATMENT PER ESD REQUIREMENTS.

· REDUCTION OF IMPERVIOUS AREAS THROUGH BETTER SITE DESIGN, ALTERNATE SURFACES, AND NON-STRUCTURALPRACTICES: THIS PLAN PROPOSES THE COMPLETE TREATMENT OF ESDV THROUGH THE USE OF NON-STRUCTURALPRACTICES.

· INTEGRATION OF EROSION AND SEDIMENT CONTROLS INTO THE STORMWATER STRATEGY: BECAUSE OF THE RELATIVELYSMALL DEVELOPMENT AREA, THE USE OF STANDARD ESC CONTROL MEASURES SUCH AS SILT FENCE, INLET PROTECTIONAND STABILIZED CONSTRUCTION ENTRANCE WILL BE USED TO PROVIDE PROTECTION FROM EROSION OF SITE SOILS.

· IMPLEMENTATION OF ESD PLANNING TECHNIQUES AND PRACTICES TO THE MAXIMUM EXTENT PRACTICABLE (MEP): ASDETAILED IN THIS REPORT ESD PLANNING AND PRACTICE HAVE BEEN IMPLEMENTED TO TREAT 100% OF THE REQUIREDESDV ON THIS PROJECT.

SITE AND RESOURCE MAPPINGPER THE MARYLAND DEPARTMENT OF THE ENVIRONMENT'S STORMWATER DESIGN MANUAL,AS REVISED PER THE MARYLAND STORMWATER MANAGEMENT ACT OF 2007, TO INCLUDEENVIRONMENTAL SITE DESIGN (ESD) TO THE MAXIMUM EXTENT PRACTICABLE (MEP),IDENTIFICATION AND MAPPING OF THE FOLLOWING SITE RESOURCES IS REQUIRED:

NATURAL RESOURCE MAPPING HAS BEEN FIELD VERIFIED BY PROJECT ENGINEER.

NEW VS. RE-DEVELOPMENT DETERMINATIONPER CURRENT MARYLAND STORMWATER MANAGEMENT REGULATIONS, DEVELOPMENTSITES WHICH CONTAIN IMPERVIOUS COVER OF 40% OR MORE ARE CONSIDEREDREDEVELOPMENT. SITE CONTAINING LESS THAN 40% IMPERVIOUS COVER ARE CONSIDEREDNEW DEVELOPMENT.

FOR THE PURPOSE OF THIS DETERMINATION THE ENTIRE PARCEL AREA IS CONSIDERED ASFOLLOWS:

TOTAL SITE/PARCEL AREA: 1.683 ACRES (64,591.1230 SF)TOTAL PROPOSED IMPERVIOUS AREA: 0.869 ACRES (37,888.0878 SF)

PERCENT IMPERVIOUS COVER: 0.869 ACRES / 1.683 ACRES = 0.5179 OR 51.79%51.79% FULL SITE IMPERVIOUSNESS = NEW DEVELOPMENT

USE OF ALTERNATIVE SURFACESFOR THE PURPOSE OF THIS PROJECT ALTERNATIVE SURFACES HAVE BEEN CONSIDERED ASFOLLOWS:

· GREEN ROOFS: THIS PROJECT DOES NOT INVOLVE ANY CONSTRUCTION OF ORRENOVATION TO ANY BUILDINGS WHERE GREEN ROOF SYSTEMS CAN BE CONSIDERED.THE DEVELOPMENT AREA DOES NOT CONTAIN EXISTING OR PROPOSED BUILDING AREA.

· PERMEABLE PAVEMENTS: WHILE PERMEABLE SURFACES HAVE BEEN CONSIDERED,PARTICULARLY IN PARKING STALL AREAS, THE RELATIVE AREA WHICH WOULDACCOMMODATE PERMEABLE PAVING WILL NOT EFFECTIVELY TREAT THE AMOUNT OFESD RUNOFF VOLUME REQUIRED.

· REINFORCED TURF: REINFORCED TURF HAS BEEN CONSIDERED ALONG THE EXACTSAME LINE OF THINKING LISTED ABOVE FOR PERMEABLE PAVEMENTS. REINFORCEDTURF DOES NOT PROVIDE AN EFFECTIVE STORMWATER MANAGEMENT SOLUTION ONTHIS SITE.

ACCORDING TO USDA WEB SOIL SURVEY DATA, SOILS ON-SITE ARE LISTED AS CHILLUM LOAM (HYDROLOGIC SOIL RATING: C).INITIAL GEOTECHNICAL INVESTIGATION PROVIDED BY PSI INC. SHOWED SIGNIFICANT LAYERS OF CLAY AND CLAYEY SANDTHROUGHOUT THE SITE. DUE TO THE EVIDENCE OF POOR SOILS, INFILTRATION IS NOT A VIABLE OPTION IN OUR GOAL TOPROVIDE ESD TO THE MEP. ADDITIONAL GEOTECHNICAL INVESTIGATION PROVIDED BY J. D. HYNES & ASSOCIATES SHOW NOINFILTRATION IN THE AREAS AVAILABLE FOR ESD PRACTICES. IMPLEMENTING THE SUBMERGED GRAVEL WETLAND ISAPPROPRIATE TO MEET ESDV & WQV REQUIREMENTS FOR THIS SITE.

ON THIS PROJECT THE FOLLOWING ESD PRACTICES ARE USED TO PROVIDE TREATMENT OF STORMWATER:

SUBMERGED GRAVEL WETLAND

SUBMERGED GRAVEL WETLAND AREAS (2) ARE USED IN TREATING A TOTAL CONTRIBUTING IMPERVIOUS AREA OF 0.6633ACRES (28,896.9335 SF) ON THIS SITE. THE TOTAL SUBMERGED GRAVEL WETLAND SURFACE AREA IS 3,355 S.F.

THE TOTAL SITE DRAINAGE AREA HAS BEEN DIVIDED INTO THREE (3) SUB-AREAS, WITH TWO (2) OF THE THREE (3) AREASGOING TO INDIVIDUAL TREATMENT PRACTICES, AND THE THIRD BEING RELEASED ALONG THE NATURAL DRAINAGE PATTERNSOF THE EXISTING PROPERTY.

SIZING FOR THE TWO (2) INDIVIDUAL PRACTICES IS AS FOLLOWS:

PROPOSED DRAINAGE AREA NO. 1

PROPOSED DRAINAGE AREA NO. 1 CONSISTS OF THE EAST PARKING AREA AND DRIVE AISLE, AS WELL AS A PORTION OF THEMAIN ENTRY INTO THE SITE, AS SHOWN ON THE ATTACHED POST-DEVELOPED STORMWATER MANAGEMENT DRAINAGE AREAMAP (SHEET SWM-POST). DRAINAGE CONTRIBUTES TO SUBMERGED GRAVEL WETLAND NO. 1 (GW-1) VIA SHEETFLOW ACROSSTHE PARKING LOT THROUGH THE STONE DIAPHRAGM AND EITHER DIRECTLY INTO THE SGW OR INTO A GRASS SWALE NORTHEND AND THEN INTO THE PRACTICE. IT IS NOTED THAT A MINIMUM OF 10% PRE-TREATMENT IS REQUIRED FOR THIS PRACTICE,SAID PRE-TREATMENT IS PROVIDED IN THE FORM OF THE GRAVEL DIAPHRAGM. THE FOLLOWING IS A SUMMARY OF PROPOSEDDRAINAGE AREA NO. 1, WITH ASSOCIATED COMPUTATIONS FOR THE SIZING OF THE PRACTICE AND TREATMENT VALUESACHIEVED:

PROPOSED DRAINAGE AREA NO. 2

PROPOSED DRAINAGE AREA NO. 2 CONSISTS OF THE NORTH PARKING AREA, DRIVE AISLE, AND ROOF AREA OF THE ENTIREPROPOSED BUILDING, AS SHOWN ON THE ATTACHED POST-DEVELOPED STORMWATER MANAGEMENT DRAINAGE AREA MAP(SHEET SWM-POST). DRAINAGE CONTRIBUTES TO SUBMERGED GRAVEL WETLAND NO. 2 (GW-2) VIA SHEETFLOW ACROSS THEPARKING LOT THROUGH THE STONE DIAPHRAGM AND EITHER DIRECTLY INTO THE SGW OR VIA DOWNSPOUT. IT IS NOTEDTHAT A MINIMUM OF 10% PRE-TREATMENT IS REQUIRED FOR THIS PRACTICE, SAID PRE-TREATMENT IS PROVIDED IN THE FORMOF A STONE DIAPHRAGM. THE FOLLOWING IS A SUMMARY OF PROPOSED DRAINAGE AREA NO. 2, WITH ASSOCIATEDCOMPUTATIONS FOR THE SIZING OF THE PRACTICE AND TREATMENT VALUES ACHIEVED:

*NOTE: HAND CALCULATIONS ARE PROVIDED ABOVE AND VARY SLIGHTLY FROM THOSE PROVIDED WITHIN THE SPREADSHEET. BOTH DO, HOWEVER SUPPORT THE FINDINGS THAT THE SITE DESIGN CONFORMS WITH THE ESD TO THE MEP METHODOLOGY.

DISCHARGE OF BOTH GW-1 AND GW-2 WILL BE CONTROLLED BY OUTFALL STRUCTURES WITH OUTLET PIPES DRAINING INTOGRAVEL LEVEL SPREADERS ALONG THE SOUTH PROPERTY LINE AND BEING RELEASED ACROSS EXISTING GRADE, THEREBYMIMICKING THE EXISTING DRAINAGE CONDITION.
