We <br /> will excavate oil seeps if necessary, and we will evaluate the <br /> issues of water drainage around the trees in the park. <br /> Please review the Work Plan. If you have questions or comments, <br /> please contact me ( 415) 620-4975 . When you are satisfied, please <br /> send your written approval to Mike McCluskey, Director of Public <br /> Works, City of Tracy. <br /> Your timely assistance is greatly appreciated. <br /> Very truly yours, <br /> D.
