While not recommended,they may be abandoned in place. However,to <br /> avoid the cost of removing the public corp fitting in the street(and replacing a <br /> portion of the public street) that serves these private lines,the fire hydrants should <br /> be relocated to the edge of the ROW. <br /> Plans revised per comment. <br /> 3) There are concerns regarding water stagnation issues for lots that feed off of Outlot <br /> B and Outlot C. It is recommended that a connection be made between these two <br /> drives to address the water gnality concern. <br /> The amount of water and the time required to fully exchange the water in the <br /> main was calculated to determine if stagnant water would result in water <br /> quality issues. <br />
