The existing volumes were last revised and adopted by <br />Resolution No. 16201 on January 22, 2024. <br />ANALYSIS <br />Attachment A (Exhibit A) summarizes revisions of the new and modified requirements incorporated into <br />the proposed resolution. These changes include updates to the asphalt paving and concrete <br />improvements section of the Standard Technical Specifications, updates to the Standard Details for <br />utilities and pavement restoration, and updates to the guidelines/checklists of the Design Criteria. A <br />complete, current file of revised Engineering Standards is available for review in the City Clerk’s Office. To <br />view the specific changes, Attachment B is a redlined version of the revisions to the Engineering <br />Standards. <br />Changes to the standards will improve constructability of the City’s infrastructure by: <br />- Clarifying common questions regarding the existing standards <br />- Standardizing requirements requested by staff during project reviews on a project-by-project <br />basis <br />- Updating code references <br />- Complying with new regulations <br />Most of the proposed revisions are editorial to correct typos, update references, and clarify existing <br />requirements. Some updates to installation procedures and materials may slightly increase construction <br />costs. For example, the new Standard Detail UT-5A/B/C (pothole restoration) specifies minimum extents <br />of pavement restoration required after potholing operation. These new details better protect the roadway <br />pavement and prevent future pavement failures by expanding the footprint of the pavement restoration <br />to allow better surface material compaction and reduce water intrusion. The associated time and cost <br />impacts of complying with the new standards for design and construction should be insignificant for most <br />private development and public works projects. <br />Other changes may result in cost savings during both design and construction. For example, the revised <br />Standard Technical Specifications Section 02 5000 (Asphalt Paving and Surfacing) and Section 02 5500 <br />(Concrete Improvements) allows for recycled base, recycled sub-base, reclaimed asphalt pavement, and <br />reclaimed concrete aggregate/fly ash, which are all less expensive than new materials. <br />The proposed update reflects changes based on feedback from the designers and contractors who use <br />these documents. The revisions follow current building codes and reflect the latest improvements in <br />design, construction technology, and materials. They also align with industry guidelines and standard <br />engineering practices. In some cases, such as the new Standard Detail UT-5A/B/C mentioned above, staff <br />are recommending slightly higher standards to increase the longevity, performance, and safety of public <br />infrastructure. These higher standards will reduce the long term maintenance costs the City incurs. <br />7.A. - Page 2 of 121 <br />8
