i"~ trees such that the total number of trees is not reduced. He emphasized that no amount of money can replace a heritage tree, and every tree that is removed must be replaced. Ms. Stern replied that this issue should be addressed in the ordinance and that the ordinance should be clear about preserving trees with no net loss of trees resulting from development. Commissioner O'Connor commented that no amount of small replanted trees could replace heritage trees that aze removed; it would take very long before they grow into heritage trees. He stated that the goal should be to not take the trees out. Commissioner Blank emphasized that the goal of the General Plan with regazd to preserving trees so there is no net loss of trees in any development should not be contradictory to the ordinance. Ms. Harryman suggested that staff review the ordinance to determine if a conflict exists; if there is no conflict, the language could certainly be added to the General Plan, and if there is a conflict or if the ordinance is vague, it could be brought before the Commission for review. Chairperson Arkin stated that he would like to add a policy to not have reverse osmosis, the process of basically filtering water and returning it into the groundwater system to be used later as drinking water. He noted that reverse osmosis was heavily debated at the 2002 election and that he would not want to have that issue back for future discussion. Paee VIII-39 Commissioner Fox requested a minor rewording of Policy 8.2 as follows: "Design develegr~etit~natural open space areas adjacent to sand and gravel harvesting azeas and Zone 7 water retention lakes...to include a protective buffer zone, similar to that on the east side of Martin Avenue, particulazly north of Busch Road °°a °'°~°'"° ~'°°°wa~° that are open to the public for recreation purposes." Ms. Harryman informed the Commission that, in reference to a conversation she recently had with Commissioner Fox regazding the buffer zone on Martin Avenue, negotiations aze taking place with Zone 7 so it does not fence off the azea and that a license agreement would be brought before the Council for that purpose. She noted that although this is not regulatory in nature as Zone 7 owns the property, the City would like to have this policy in place. Ms. Stern clarified that the "Sand and Gravel" section refers to those azeas that are active sand and gravel quarries rather than those that have transitioned out of sand and gravel into recreational uses. Commissioner Fox noted that Martin Avenue is no longer active and that Lake I is currently being utilized for groundwater retention. /"` PLANNING COMMISSION MINUTES, May 24, 2006 Page 8 of 34
