We offer the following observations,comments, and recommendations for your <br /> consideration: <br /> l. The Applicant is proposing to iznport a large quantity of material to revise site grades. Therefore,the <br /> City should consider the following: <br /> a. The City Engineer should be aIlowed ta inspect any fill being imported to the site prior to it being <br /> placed. <br /> b. The Applicant should confirm with the City Engineer acceptable hours of truck hauling and pmvide <br /> documentation on the haul route to be used. Acceptable hours and haul route should be approved <br /> prior to the importing of any riprap or fill. <br /> c. The City Engitneer should inspect roadways on haut route prior to and following completion of work <br /> to dete�rmine whether adverse impacts have occwrred.The applicant should be responsible for the <br /> repair to roadways for any adverse impacts. <br /> 2. The Grading Plan has been adequately revised to maintain the existing surface overflow on the south side <br /> of the wetland. Caze should be eaercised during construction to ensure the surface overflow is <br /> maintained at existing eIevations. <br /> 3. In order to coordinate work between the Applicant,Contractor,City,and MCWD,a Pre-Construction <br /> meetrng should be held prior to any land disturbing activities. This would help ensure the Applicant and <br /> Contractar aze awaze of ail potential issues and work perfonned is within City's expectations. <br /> If you have any questions or comments,please contact me to discuss at(952)44$-8838. <br /> Sincerely, <br /> BOLTON&MENK, INC. <br /> �BCd�ttG Ic��a� <br /> �� . <br /> Robert E.
