confirming the percentage reduction in potable water consumption compared to
the baseline;
� Updated narrative describing all installed water conservation strategies;
� Manufacturer information for all installed fixtures and fittings indicating flow rates

within this credit may be achieved through the use recycled water.
� All pipes containing recycled water must be color coded in order to easily
distinguish them from potable water pipes.
