Developer Extension Process
Woodinville Water District is a special purpose District and relies on Developers/ Property owners to extend existing water and sewer mains. We are here to assist and make sure that the District design and construction standards are being met.
Developer Extension Agreement is used for water and sewer main extensions.
Service Connection Agreements are used for fire hydrant extensions/ relocations, fire sprinkler vaults, water service connections for short plats that connect off an existing water main, and new side sewer connections.
A Developer Extension Agreement and a Service Connection Agreement follow the same Steps 1-5 below.
- Step 1: Preparation
- Step 2: Plan Submittal
- Step 3: Design Review
- Step 4: Construction
- Step 5: Project Closeout
The steps that need to be taken to prepare for a developer extension is to determine if one is needed. For new short plats and subdivisions preliminary plat approval must occur and a water/ sewer availability certificate will be required. If you are interested in water or sewer service for a single property, the water/ sewer main must cross the entire frontage of the property and you must meet distance thresholds for private service lines. If you are unsure call the District.
It will be your responsibility to hire a professional licensed civil engineer to provide civil engineering plans showing the water/ sewer improvements you are planning. The design must meet the Woodinville Water District’s engineering standard specifications.
Water and Sewer plans must be submitted on separate sets.
All civil engineering plans saved from their original design software to a pdf vector format for optimal OCR readability. 150 dpi or higher. Flattened.
For a Developer Extension Agreement:
- pre-application form shall be filled out and given to the District.
- Pdf plan submitted.
- $3,000 each (water/sewer) administrative fee
- $1,500 Latecomer Agreement administrative fee (if a Latecomer is requested on the pre-application form. This will be due prior to submitting invoices to the District for review for the construction costs.
For Service Connection Agreement:
- Pdf plan submitted.
- $2,000 each (water/ sewer) administrative fee
The District has a consultant engineer who will prepare the agreements and provide the design review and construction inspection deposit fees based off the quality of the pdf plans that were submitted.
The District Engineering Technician will send the Developer the agreements. The agreement will need to be signed under notary by the Developer. The administration fee and design review deposit will need to be paid prior to the start of any design review. The consultant engineer and District engineering technician will review the first submitted plans and send the Developers engineer the first round of revisions to be made.
It is usually after the second plan submittal that District staff provides their comments. The revisions go back and forth between the Developer engineer and WWD staff until the District is satisfied with the end product. The Developer’s engineer will then be directed to plot the plans on mylar with the engineer’s stamp and wet signature on each plan. The mylars are delivered to the District for Construction approval signatures.
The approved for construction mylars are signed by the District engineer. The Districts Consultant Engineer will prepare a pre-construction check-list to the Developer to complete prior to scheduling a pre-construction meeting with the Developer, Developer’s contractor, District staff and District’s Consultant engineer.
The District Consultant Engineer will apply for a right of way permit from the jurisdiction in which the work is residing if there is work to be done in the road. A performance bond will be required to cover any work in the right of ways. The Districts Consultant Engineer provides the cost of the Performance bonds. The Construction Inspection deposit noted in the Agreement will be required to be paid prior to the pre-construction meeting. Material Submittals will need to be submitted (pdf format) to the District Consulting Engineer for review.
If your development is in the City of Woodinville Central Business District you will need to pay to the District the Sewer CBD-CIC fee prior to the pre-construction meeting.
Construction can start after the pre-construction meeting and after the District Inspector notifies the City/ County right of way inspector on the start day of the project.
Note: if any design changes occur in the field the contractor must stop work immediately and notify the District inspector. The District inspector will determine if the Developer’s engineer needs to provide the District Consultant engineer and the Engineer technician plans showing the modifications.
In order to obtain final approval from the District you must submit the following documents at least 10 days prior to the next Board meeting (the board meets every 1st and 3rd Tuesday of each month):
- All easements signed and returned (if applicable)
- As-built drawings completed and approved, including mylars and digital copies
- All fees paid to close out Developer Extension
- Construction completed
- Final inspection and punch list completed
- All permits closed out (for example, Right of Way)
- Bill of sale signed and returned.
- Cost Summary form filled out.
There will be no prior approval until these items are completed to the District’s satisfaction.
Note: After final approval from the District water meters can be applied for. If sewer connections are needed sewer permits and sewer system development charges will need to be paid for.
For side sewer for retail the side sewer connection will be plugged until the District receives a completed non-residential capacity form, and sewer permit fees and system development charges are paid. It is illegal for anyone but District staff to remove these plugs from the side sewers.
After the project has been accepted by the District Board of Commissioners the Developer will be contacted to provide a 2-year Maintenance Bond. The amount of this bond is 10% of the cost of construction. The total is calculated off the Bill of Sale amount that the Developer provides to the District. The minimum amount for a Maintenance Bond is $2,000.00. Once the 2-year Maintenance Bond is received any existing Performance Bond will be released.
After two years of the board acceptance date the District Inspector and Operations Department will reinspect the project and report any punch list items that need to be completed. Once these items are taken care of by the Developers contractor, the maintenance bond can be released and the project is deemed fully complete.
