GENERAL INFORMATION: The submitted documents for the above-mentioned project, as outlined in the cover letter, have been reviewed. The following comments address areas of concern, non-compliance with the governing code, potential errors, or omissions in the proposed design. The appropriate design professional must address each comment below and submit a written response in addition to revised plans and calculations if necessary. Please cloud any revisions made to the construction drawings and provide the date of the latest revision on each revised sheet. GENERAL COMMENTS: Please provide additional code rationale to justify building design. The plans appear to be preliminary and will require additional design and review. General: Resolved. Resolved. Resolved. No specifications will be used for this project. Deferred Submittal or Separate Permit: General: Deferred submittal: Please specify a complete list of deferred submittal designs needed for this project. deferred submittals require building official permission. Exit sign locations: Plans, Sheet A103, indicate that the location of exit signs is a bidder design. 2nd Review:Please address this item. Sheet 103 indicates exit signs will be bidder design. Design of the detention vault: Due to the location of the detention vault, the design is needed prior to foundation installation and must be reviewed as part of this permit review. Please submit full design, including calculations, plans and details for City review of the vault. Confirm loading and coordinate with recommendations in the Geotechnical report. 2nd Review:Please address this item. From a fire-rated perspective. The columns from the Type IA building appear to be included as a part of the tank walls and the top of the vault serves as the floor of the building. Therefore, the design appears to be substantial and therefore likely to meet fire rated Table 601 design, however, wall and floor designs have not been designated. Please confirm the fire rating meeting Type I-A construction.And address the fire rating of the access lid. G4 Continued -2nd Review:Please coordinate the response to include all elements, deferred designs etc. The (2) lists provided (Sheet G001 and Sheet S0.01) appear to be incomplete or not consolidated based on the submitted plans and letter of response.

No sheet flow of drainage should be designed to flow over walking or exit hardscapes. 2nd Review: Please provide response to this item.No response appears to be provided from the landscape design team. General: Sheet AS100: Please specify the setback to canopy structures and all roof projections and eave extensions show dimensions to property liens and to easements if any are adjacent. Provide dimensions showing how far the canopy will project from the face of the building. 2nd Review:Please see item G11, and Sheet A111 – thereare plan notes indicating a 10ft snopub easement (C7.00) is required from Hwy 99. The canopy is not shown on Sheet C7.00. The canopy was not fully dimensioned on the A sheet (A111 and A113) etc. and therefore both dimensions and the distance (property line:canopy) is needed showing compliance with snopudeasement: 10ft setback. Sheet A113 clearly shows that a 4’9” setback (instead of 10’0”) has been provided.Please document how this is acceptible by the AHJand or revise the plans to show a 10 foot setback. Occupancy Classification: (IBC Chapter 3) Resolved. Additional clarification may be needed regarding notes that may not apply to this project.
