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).
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, 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."
Alternative:Attached additions less than 40% of the existing living space of the existing residence and build at or higher than elevation of the existing slab, Elevation Certificate is not required.
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.
The Hydrology and Hydraulic report was incomplete/insufficient for determining the base flood elevation (BFE). 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)
Project Address: Please use ½ address.
Sheet A1:
Site plan: Please revise plan to show grade slope minimum 5% away from the building foundation wall; 2% on the paved or concrete surface.
Sheet A2:
Please relocate the new water heater to the outside so it can be accessible for the ADU.
Exterior steps: Please provide handrails when four or more steps are provided. Please show handrails and guardrails and provide detail on the plan.
Handrails shall not be less than 34” or more than 38” above the noising of tread. Handrail shall be continuous the full length of the flight.
Guardrail shall be 42” in height. Openings in guardrails shall not allow passage of a 4” diameter sphere.
Please show rises and runs dimensions (7.75” maximum rise, 11” treads).
Wall between ADU and existing residence should be protected with one-hour construction. Please show on plan and provide one-hour wall construction details. Clearly cross-reference detail onto the plan.
Sheet SD-1:
Detail 01: please provide the following for wood protection again concrete –
Specify corrosion resistance flashing.
Provide/show metal weep screed at the bottom end of the flashing
Please provide air gap between the concrete and existing wall studs, and the air gap shall be sealed/filled with caulking sealant.
