Rough Grade Process & Checklist 1 Review Timeline • Clearing and grading review and approval generally takes 4-5 weeks. • Rough grade review and approval generally take 8-10 weeks. • Approved Construction Plan Set and bonds could be required to be submitted prior to permits being issued. Wet Weather A city approved, “wet weather plan”, for erosion and sediment control, is required for any work anticipated to occur during the rainy season, October 1st and April 30th. An Erosion Control Bond may be required as part of the Wet Weather Plan if there will be work near critical areas such as wetlands, streams, steep slopes or their buffers. There are fees associated with review. Contact the development engineering department if your project needs to undergo a wet weather plan review. • Wet Weather Approval Block (PDF) • Wet Weather Checklist (PDF) ROUGH GRADE PERMIT (RGD) PROCESS AND CHECKLIST DEVELOPMENT ENGINEERING ---PAGE BREAK--- Refer to the Redmond Municipal Code Chapter 15.24.070 Rough Grade Projects for a listing of the prerequisites of application, and submittal requirements. When you are ready to begin preparation of your rough grade drawings, call the stormwater reviewer to discuss what work items are to be included. The submittal process is not as formal as with the Coordinated Civil Review, fee payment and submittal materials can be provided at a meeting with only the storm reviewer. The Stormwater Engineer assigned to the project will then coordinate the rough grade review across City departments. The most common reason for delay of approval is for including work items that go beyond the limited scope of a Rough Grade Permit as described in RMC Chapter 15. Once the reviewers have determined that all relevant checklist items have been addressed and the project is ready for approval it is presented to the City of Redmond Tech- nical Committee. As with the CCR process our goal is to obtain approval with two review cycles. The applicable fees are found on the Division of Public Works Stormwater Fee table. This link provides the fee table; • Development Engineering Fees • Redmond ePermitting Services (REPS) • 2022-Stormwater-Technical-Notebook-Update (redmond.gov) • Clear and Rough Grade Permit STEP : 2 The following information should be submitted prior to the full application submittal so that staff can establish plan review fees and create invoices to facilitate fee payment: Land Area Cleared/Disturbed (sq. ft.) Amount of Material Moved (cubic yds.) The applicant must upload plans to the E-Review Portal Redmond ePermitting Services (REPS) See the attached instructions title Electronic Plan Review – Uploading Submittal Materials and Viewing Issues Matrix & Marked Up Drawings. Please refer to the attached Intake Checklist for required submittal items. Note: You should contact appropriate City staff, prior to submission, if there are any questions regarding submittal requirements. Marking a checklist item as “Not Applicable” or “N/A” without first speaking with staff will likely result in the submittal being rejected. Rough Grade Projects are intended to allow for earthwork prior to full civil plan set approval. Erosion control is of par- amount importance. Under some conditions the proposed stormwater pond or underground vault can be constructed as part of the rough grade to provide an important erosion control BMP. What is not allowed under rough grade permits: Retaining wall or rockeries Paving Water /sewer or other utility work not related to erosion control Work in the right-of-way Site stabilization is permitted, but landscaping generally is not. If your submittal omits any checklist items the City will document and explain the deficiencies to you. You will need to correct the deficiencies and contact your Stormwater Engineer to arrange another intake when you are ready. STEP 3: INTAKE MEETING Once the checklist is satisfied, your City reviewers will evaluate your plans for compliance with development standards. Each reviewer will redline any compliance issues on the plans and document comments on the consolidated issues matrix. The marked up plans and issues matrix attached to project will be made available through the E- Track Portal (Redmond ePermitting Services (REPS) STEP 1: ROUGH GRADE LEAD ---PAGE BREAK--- Your Project Lead reviews all the comments made and check for potential conflicts between reviewers. If conflicts are noted, an internal staff meeting is held to resolve them. At this point, you will be able to access the plans with comments through the E-Track Portal. Your ability to access the plans will occur no later than Day 25, thus allowing you time to consider the comments and formulate any questions or proposed solutions. If non-compliance remains in your plans that can only be rectified with a third cycle review, these comments will be noted and explained. You will revise the plans and resubmit. The City will review and comment as before. The City may ask you to participate in a diagnosis meeting to determine why extra cycles were necessary to help improve the process or the checklist. STEP 4: APPLICANT SUBMITS APPEOVED CONSTRUCTION PLAN SET, BONDS AND PAYS INSPECTION FEES Upon completing the “Rough Grade” process, the developer submits the final rough grade plans on a full size paper set to the City of Redmond Development Services Center for approval signatures by City staff. Please coordinate with your assigned Project Lead before submitting the final plans. The following items must be submitted prior to or along with “Approved Construction Plan Set” for City approval: Pay inspection fees and remaining plan review fees, if applicable Post Restoration Bond or Cash Deposit ($10/CY of material moved) Rough Grade Bond Form Submit electronic copy of rough grade design drawings Submit electronic copy of stormwater report including calculations for interim erosion control ---PAGE BREAK--- Rough Grade Permit (RGD) Process and Intake Checklist 4 Project Name: City Stormwater Engineer: Phone: Email: Design Engineer: Phone: Email: Electronic plans that do not meet the requirements below will fail and result in the application being deemed incomplete and will not be reviewed until complete. The applicant MUST upload the following plans and supporting documents through E-Review Portal Redmond ePermitting Services (REPS) Please see the Electronic Plan Review - Uploading Submittal Materials and Viewing Issues Matrix & Marked Up Drawings handout. A. File Naming Standards: Indicate the naming convention in which the particular submittal must be named. For example, the Grading Plans must be named Grading Plans and Drainage Report must be named Drainage Report. Any additional documents such as reports, calculations, photos and other supporting documents should also be named according to their con- tent. C. Acceptable File Types: Plans: Plans must be submitted in a PDF format. Documents: Calculations, reports and other supporting documents (non-drawing files) must be uploaded as a PDF B. Plan Sheet Standards: All plans must be drawn to scale, as specifically identified in the checklist, and each sheet shall state the scale. D. Plan Orientation: All plans must be uploaded in “landscape” format in the horizontal position. SPECIAL NOTE: The Checklist requirements may change periodically. These checklist requirements are dated August 2014.
