A minimum one hundred foot (100') buffer park shall be established along the eastern border of the Glen Oaks PUD adjacent to Interstate 35. Said buffer park shall provide reasonable noise and visual screening/buffering of negative aspects of Interstate 35 on land within the Glen Oaks PUD. Prior to development within any part of any parcel within the Glen Oaks PUD, a buffer plan shall be reviewed and approved by the city which illustrates that use of berms and tree plantings to effectively buffer the residential uses within the Glen Oaks PUD from Interstate 35. The minimum one hundred foot (100') buffer park may be reduced in distance upon the demonstration of effective and adequate noise and visual screening/buffering of Interstate 35 from residential uses as approved on the required buffer plan. Internal streets may be permitted within the buffer park upon review and approval by the city. (Ord. 1007, 5-26-1992)
