Note: Numbers in parenthesis (unless otherwise noted) refer to code sections of the 2019 California Residential Code (CRC); 2019 California Building Code (CBC); CMC = 2019 California Mechanical Code; CPC = 2019 California Plumbing Code; CEC = 2019 California Electrical Code; T = Table; ICC = International Code Council.All items noted on this plan check report must be addressed. If you feel that an item is not applicable to your project, note “N/A” and discuss the reason with the plan checker.Please indicate the sheet number and detail to the right of each correction, or note the number on the plans where the correction is made. Resubmit marked original, calculations and this correction sheet. A separate sheet for response may be used.Resubmit 3corrected sets of plans.
The applicant shall obtain clearances/approvals for the following, prior to building permit issuance:
-Planning Division approval on the corrected/final set of drawings (647-5804). Previously
approved plans should be submitted to expedite the process.
-Police Department approval on the corrected/final set of drawings (647-5840).
-Public Works Agency approval (647-5039).
- Proof of Worker's Compensation Insurance shall be required at the time of permit issuance.
- School District Compliance Certificate; and a copy of the building permit application, signed by
the plan check engineer, shall be required by the School District to verify the scope of the work.
-Grading Permit. Application is made through the Building Safety Division (647-5800) and the
plan review is by the Public Works Agency (647-5039).
This project is in a special flood hazard area designated on the flood insurance rate map (FIRM) as zone A or AE. This zone requires that the lowest finish floor elevation (including basement) of the structure shall be at (or above) base flood elevation determined by a hydrology study for the A zone, or at (or above) the base flood elevation specified for the AE zone, on the flood insurance rate map. All elevations must be referenced to the National Geodetic Vertical Datum. Reference should be made to the Flood Plain Management Ordinance, Santa Ana Municipal Code, Chapter 7, for complete requirements. Drawings shall show compliance with said ordinance including noting flood zone and finish floor elevation."
Note on plans: "A Federal Emergency Management Agency National Flood Insurance Program ELEVATION CERTIFICATE shall be completed by a California Licensed Land Surveyor or California Registered Civil Engineer who is authorized to practice land surveying. The completed ELEVATION CERTIFICATE must be submitted to the Building Inspector at the time of foundation inspection, and a final certificate must be submitted at the time of final inspection."
The Elevation Certificate shall be reproduced/imprinted on the final set of plan.
Get the Base Flood Elevation for All New Development in Zone A
Any new development or substantial improvement within Zone A needs to have a BFE determined as part of the application process. To start, you’re required to look through what already exists. Here are all the possible places you’ll find data that could provide the BFE:
Check the Flood Insurance Rate Maps (FIRM), Flood Insurance Study and municipal records, and check with your Regional Floodplain Manager regarding records and studies.
Contact your Regional Floodplain Manager to see if FEMA, US Geological Survey, Army Corps of Engineers, National Resources Conservation Service, or Housing and Urban Development have conducted studies to determine BFE data for the site. The USGS may have also documented high water marks.
If a body of water forms a boundary between two communities, the community on the other side may have a detailed study. Such base flood data are valid for both sides of a body of water.
Existing State studies, including VTrans hydraulics studies for any nearby bridge or major culvert might provide BFE.
Hydro-power dams likely have a study providing BFE for their federal license.
You could use data from any of these studies as long as they:
reasonably reflect flooding conditions expected during the base flood,
are not known to be technically incorrect, and
represent the best data available.
If the BFE Doesn’t Already Exist, Hire Someone to Determine It
If none of the sources above are able to provide the BFE, the next step is likely to require the property owner or developer to commision a study to determine it. This requires hiring a surveyor or engineer and provides information about the channel and local valley cross-sections, hydrology, and hydraulics. Detailed studies typically use modeling programs such as the US Army Corps of Engineers HEC-RAS. The people conducting this study should review FEMA’s document on Managing Floodplain Development in Approximate Zone A Areas.
Zone A floodplains are those areas have not determined Base Flood Elevation (BFE). Below are some useful information provided on Official Vermont Government Website for your use. (Copied from the website: https://floodtraining.vermont.gov/protection-tools/zone-a)
Sheet CS-1:
The project is located in a Flood Zone. Please provide information as required above.
Site Plan: Please show surface drainage slope and pattern. Coordinate with Grading Plan.
Building Data: Please revise note to specify “The design is complied with the 2019 CBC, …”
Scope of Work: Please add the following notes for the Photovoltaic system – A minimum of 1.8KWDC Photovoltaic system shall be permitted and installed prior to building final inspection sign off.
Sheet A-1:
Per energy calculation, 2x6 exterior walls are required for the R-21 wall insulation. Please coordinate and revise plan accordingly.
The 4040 single hung window would not provide 24” clear height for the emergency escape opening. Please revise plan accordingly.
Please provide building section to show building envelope, including wall and ceiling insulation.
Sheet A-4:
Please show/provide an exhaust hood (minimum 100 cfm) at the kitchen area.
Please show location of whole-house vent on the plan.
Title 24-1 & 2:
Plan showed slab on grade. Please revise Title 24 calculation to for slab on grade.
Structural Review Comment:
2x6 stud walls may be required per Energy Calculation. Please coordinate and revise plan accordingly.
Ridge: Please specify member size for the ridge board.
Foundation:
Please revise slab specification to provide 5” thick concrete slab with #4 rebar at 12” on center, each way. (Per soil report)
Pad footing: Please revise pad footing schedule to provide 24” deep footing.
Referenced detail 1 and 2 on sheet SD-1: Please revise details to show minimum 24” deep footing. (Per soil report)
Referenced detail 1/SD-1: Please revise detail to show/provide minimum 15” wide continuous footing. (Per soil report)
Final foundation plan and details shall be submitted to the geotechnical engineer of record for final review and approval. The geotechnical engineer should “reviewed” stamp the plan for general conformance with the soil report finding and recommendation.
