Detention Vault

What is it?

You need a Detention Vault Permit when installing a new vault or repair work to an existing vault. This can be a storm water detention vault.

How Much Does it Cost?

Fees are based on the value of your project. You pay a plan review fee when you submit your plans and the rest when you pick up your permit. See the Fee Schedule (A-Z) page to download the Miscellaneous Fee Schedule for fee related information.

How Long Does It Take?

We try to finish our initial review of new and additions permit in 21 calendar days from submittal. How long it takes to get the final permit depends on how complex your project is and how many corrections, if any, you need to make.  

Steps to Get Your Permit

1. Research
Get your property information. Find property information to help you plan your project. Use our Property Viewer Interactive Map.

Determine restrictions to your project. Research the Redmond Zoning Code to determine what occupancies are allowed in the building and what land uses are allowed in that zoning area.
 
Find incentives for your project. Research the City’s different Green Building Incentives that might apply to your project.

Request a Pre-Application Meeting (optional). We recommend pre-application meeting for very complex projects, including buildings with unusual structural systems, substantial alterations, or work in environmentally critical areas or shorelines. Pre-application meetings are scheduled on Thursdays. For more information see Pre-Application Conference Tip Sheet.                    

2. Start Permit Application
Apply for exemptions. You may need an exemption if your project is located in an environmentally critical area or near the shoreline.
 
Prepare your plans. Plans should be electronic and should be to scale and easy to read.
