IN GENERAL, REGULAR MOWING OF ANY GRASS SWALES AND STORAGE PONDS WILL BE REQUIRED TO PREVENTSTANDING WATER, CLOGGING, AND THE GROWTH OF WEEDS AND WETLAND PLANTS. MORE SUBSTANTIAL MAINTENANCE,SUCH AS SEDIMENT REMOVAL WITH HEAVY EQUIPMENT, MAY BE REQUIRED IN COMING DECADES TO RESTORE RETENTIONPOND VOLUME.ALL MAINTENANCE AND REPAIR SHOULD BE PRIORITIZED AND SCHEDULED IN ADVANCE. TYPICAL MAINTENANCE ITEMSINCLUDE REMOVING OBSTRUCTIONS FROM FENCING, MOWING GRASS AND WEEDS, TREE MAINTENANCE TO PREVENT LIMBSFROM FALLING AND BLOCKING SWALES, AND ESTABLISHING GROUNDCOVER ON BARE GROUND.
