These plugs are seasonal are not available this <br />time of year; therefore Design Engineering has requested that 1 gallon plants be planted <br />instead. (PCO 3) <br />ESTIMATED COST = $ 1500 <br />At the Maple Street Bike Trail rest area the contractor installed a new double check <br />backflow device per the contract documents. Double check backflow devices are not <br />permitted for irrigation use per S.A.M.C. Sec. 39 -28; therefore the device needs to be <br />removed and replaced with a lead -free reduced pressure principle device.

Most of the properties have a block wall adjacent to the rest area that provides <br />security and screening of the property from users of the trail. Two of the properties have <br />makeshift fences that offer little screening and security from the trail users. Design <br />Engineering has requested that a chain link fence be installed and vines planted along the <br />property line at these locations.
