CITY OF LODI COUNCIL COMMUNICATION AGENDA TITLE: Adopt Group 1 of Countywide Improvement Standards MEETING DATE: March 3, 1993 PREPARED BY: Public Works Director RECOMMENDED ACTION: That the City Council adopt Group 1 of the Countywide Improvement Standards and authorize the Public Works Director to adopt and revise future Improvement Standards (Standard Plans). BACKGROUND INFORMATION: The Countywide Improvement Standards Committee was formed by the Public Works Directors of the jurisdictions within San Joaquin County for the purpose of developing uniform improvement standards than would be used throughout San Joaquin County. The City of Lodi refers to these improvement standards as Standard Plans. The Committee started meeting in October 1991 and has held monthly meetings since that time. To date, the Committee has reviewed various types of curb, gutter and sidewalk details and driveway details. The first group of Improvement Standards (attached) includes concrete construction notes, expansion joints, weakened plane joints and score lines, roll curb, gutter and sidewalk, and vertical curb, gutter and sidewalk and is now ready for adoption. The Committee solicited comments from engineers, contractors and concrete plants in the County; however, the response from the private sector was minimal. All comments were reviewed and were incorporated into the drawings where possible. Adoption of these Standard Plans will benefit all communities as well as the building industry in that having a uniform set of standards within the County should have a positive effect on lowering construction costs. Contractors will know that the construction standards will be the same throughout the County and they will no longer need to check each jurisdiction's Standard Plans. The Countywide Improvement Standards will be drawn in a different format than Lodi 's Standard Plans so that contractors will know the difference between the two. The Committee is continuing to meet to prepare additional Standard Plans for countywide adoption. APPROVED'__ THOMAS A.
