1. PROJECT DESCRIPTION
THIS PROJECT CONSISTS OF DEMOLISHING A STORAGE SHED AND REPLACING IT WITH A NEW
OPERATIONS BUILDING, AND REPAVING (MILL AND PAVE) THE EXISTING PARKING LOT. THE NEW OPERATIONS BUILDING WILL BE CONSTRUCTED ON A 6-INCH CONCRETE SLAB AND WILL CONSIST
OF A SINGLE ENCLOSED OFFICE, OPEN OFFICE, CONFERENCE ROOM, TELECOM ROOM, UNISEX
RESTROOM WITH LOCKERS AND SHOWER, SUPPLY CLOST, AND WILL REQUIRE ALL UTILITIES TO BE COMPLETE AND FUNCTIONAL. THE EXISTING ASPHALT PARKING AREA WILL BE MILLED 2-INCHES AND NEW HOT-MIX ASPHALT WILL BE PAVED TO MATCH THE EXISTING SURFACE ELEVATION AND
GRADE. A NEW 4-INCH THICK CONCRETE SIDEWALK WILL BE CONSTRUCTED FROM THE NEW
OPERATIONS BUILDING TO THE EXISTING ADMINISTRATION BUILDING.
THE PROJECT'S TOTAL LAND DISTURBANCE IS 0.03 ACRES (1,143 SQUARE FEET) FROM
CONSTRUCTION OF THE NEW SIDEWALK (0.02 ACRES) AND ADJACENT GRADING (0.01 ACRES).
2. EXISTING SITE CONDITIONS
THE EXISTING STORAGE SHED IS A 1,200 SQUARE FEET FRAMED, SLAB ON GRADE FACILITY.
THE EXISTING ADMINISTRATION BUILDING IS A 4,400 SQUARE FEET CONCRETE BLOCK FACILITY CONSISTING PARTLY OF OFFICE SPACE AND GARAGE SPACE. THE SIZE OF THE EXISTING ASPHALT
PARKING LOT IS APPROXIMATELY 13,822 SQUARE FEET.
3. ADJACENT AREAS
ALL ADJACENT AREAS WITHIN THE EXISTING PERIMETER FENCE IS PROPERTY OF U.S. ARMY
CORPS OF ENGINEERS - NORFOLK DISTRICT. THE OWNER OF THE PROPERTY IS THE UNITED
STATES GOVERNMENT. THE PROPOSED WORK IS LOCATED AT THE MAIN ENTRANCE OF THE
CRANEY ISLAND PROJECT OFFICE. IMMEDIATELY TO THE SOUTH AND WEST OF THE PROJECT SITE
ARE RESIDENTIAL PROPERTIES. THE AREA TO THE NORTH OF THE PROJECT SITE IS A
CONCRETE-STEP RETAINING WALL APPROXIMATELY 9 FEET IN HEIGHT FOLLOWED BY A
LOWER-LYING AREA THAT LEADS TO THE JAMES RIVER . THE AREA TO THE EAST OF THE PROJECT SITE IS A PAVED CONCRETE AREA AND THE CONTINUATION OF THE CRANEY ISLAND PROPERTY.
4. OFFSITE AREAS
THERE ARE NO OFFSITE AREAS DEFINED FOR THIS PROJECT.
5. SOILS
A SUBSURFACE EXPLORATION AND TESTING WAS PERFORMED IN JANUARY 2022 IN
PREPARATION FOR THE DESIGN OF THE BUILDING FOUNDATION AND RECOMMENDATIONS FOR
CONSTRUCTION. THREE PRIMARY STRATA ARE LOCATED BENEATH PROJECT. BENEATH A THE
SURFACE LAYER (TOPSOIL OR ASPHALT PAVED AREA), THERE IS APPROXIMATELY 3.5 FEET OF
POTENTIAL FILL MATERIAL, MOSTLY OF POORLY GRADED SAND WITH SILT AND ALSO CLAYEY
SAND. THE NEXT 15 FEET BELOW THAT IS PREDOMINATELY FINE-GRAINED SILTY SAND, UNDERLAIN
BY A MIXTURE OF SAND, SILT, AND GRAVEL TO THE 30 FEET BELOW GROUND SURFACE.
GROUNDWATER AT THE SITE IS APPROXIMATELY 13.5 FEET BELOW GROUND SURFACE.
6. CRITICAL AREAS
THERE ARE NO CRITICAL AREAS DEFINED FOR THIS PROJECT.
7. EROSION AND SEDIMENT CONTROL MEASURES
UNLESS OTHERWISE INDICATED, ALL VEGETATED AND STRUCTURAL ESC CONTROL PRACTICES
SHALL BE CONSTRUCTED AND MAINTAINED ACCORDING TO THE LATEST EDITION OF THE
MINIMUM STANDARDS AND SPECIFICATIONS OF THE VIRGINIA EROSION AND SEDIMENT
CONTROL HANDBOOK (VESCH) APPLICABLE TO THE COASTAL REGION OF VIRGINIA. THE
MINIMUM STANDARDS OF THE VESCH SHALL BE ADHERED TO BEFORE, DURING, AND AFTER
CONSTRUCTION, UNLESS OTHERWISE WAIVED OR APPROVED BY A VARIANCE. REFER TO THE
CONSTRUCTION PLANS FOR DETAILS AND LOCATIONS ASSOCIATED WITH THE CONTROL
MEASURES.
7.1. GENERAL
7.1.1. A COPY OF THE APPROVED ESC PLAN AND THE VESCH SHALL BE MAINTAINED ON THE
SITE AT ALL TIMES.
7.1.2. PRIOR TO COMMENCING LAND DISTURBING ACTIVITIES IN AREAS OTHER THAN
INDICATED ON THE ESC PLANS (INCLUDING, BUT NOT LIMITED TO OFF-SITE BORROW OR
WASTE AREAS), THE CONTRACTOR SHALL SUBMIT A SUPPLEMENTARY ESC PLAN TO THE

DURING LAND DISTURBING ACTIVITIES.
8.2. THE WESTERN HALF OF THE ASPHALT PARKING AREA DRAINS VIA SHEET FLOW TO THE

SEDIMENT AND THE DISTURBED SOIL AREAS RESULTING FROM THE DISPOSITION OF
TEMPORARY MEASURES SHALL BE PERMANENTLY STABILIZED TO PREVENT FURTHER
EROSION AND SEDIMENTATION.
8.6. WHENEVER A SLOPE FACE HAS WATER SEEPING FROM IT, ADEQUATE DRAINAGE OR OTHER
PROTECTION SHALL BE PROVIDED TO ENSURE THE SAFETY AND STABILITY OF THE SLOPE.
8.7. ANY AND ALL MATERIAL TRANSPORTED ONTO A PUBLIC OR PRIVATE ROAD SURFACE WILL BE
REMOVED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM

BE REMOVED WHEN DEPOSITS REACH APPROXIMATELY ONE-HALF THE HEIGHT OF THE
BARRIER.
11.3.5. ANY SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE SILT FENCE IS NO
LONGER REQUIRED SHALL BE DRESSED TO CONFORM TO THE EXISTING GRADE,
PREPARED AND SEEDED.
11.3.6. REMOVAL. SILT FENCE SHALL BE REMOVED WHEN THEY HAVE SERVED THEIR
