Janice Stem City of Pleasanton P .gc 3 R 8.5 4 I.) The Plan refers to Shadow ('lift's as a water supply lake. but it would be more accurate to list Lake del Valle instead- 2.) Again, listing "active" recreation as defined in the foot and analogizing the reference to the Chain of Lakes recreation to that of Shadow Cliffs, is 19.11 potentially misleading to the reader, To protect the water quality of these crucial water supply lakes, it is highly unlikely that the same active recreation that goes on at Shadow Cliffs would be considered for the hikes nearest to the heart of Pleasanton,., i.e., Lakes II, 1, and Cope, Consider adding language here that talks about coordinating recreational opportunities with Zone 7's COLs Master Plan when it gets underway (probably staving about 2012 or 2013).

Zone 7 will examine other ways to prevent sediment from being trapped in the lakes, so the characterization of the Chain of Lakes for sediment detention is not appropriate- Please change all references. l he following Comments in the table below refer to the General Plan Update's Draft EIR. 2 2 First Again. it appears that a title of `Water Management, 1labitat, hul let and Recreation" would lit the description of the uses for this land better. Would like to see a reference to coordinating with Zone Ts future Chain of Lakes Master Plan.
