THE INTENT OF THIS PLAN IS TO ELIMINATE THE EXISTING PERMANENT POOL AREA IN THE REAR YARD BY MAINTAINING AN UNDERDRAIN SYSTEM WITH AN OUTLET ELEVATION OF 297.52. THE UNDERDRAIN WILL PROVIDE POSITIVE DRAINAGE UNDER NORMAL CONDITIONS, WHILE AN OVERFLOW/BYPASS SYSTEM WILL ALLOW TEMPORARY PONDING WITHIN THE REGRADED REAR YARD DURING SEASONALLY FLOODED CONDITIONS. THE RESULTING GRADING IS INTENDED TO PROVIDE A REAR YARD THAT IS GENERALLY DRAINED, MOWABLE, AND MAINTAINABLE BY THE PROPERTY OWNER WHILE WORKING WITH THE CULVERT INVERTS THAT EXIST. SEE NYLOPLAST DETAIL ENCLOSED WITH THIS PLAN PLACE NON-WOVEN GEOTEXTILE AROUND UNDERDRAIN TRENCH AGGREGATE SEED AND STABILIZE NEWLY GRADED SWALE UPON COMPLETION OF FILL PLACEMENT
