Therefore, plans or other materials requiring engineering review and approval shall be submitted directly to Engineering Services. The remainder of this section describes the process and the minimum requirements for submittals. 1-100 PREDESIGN MEETING Applicants are encouraged to meet with the Engineering Services Staff prior to final design and plan submittal. All plans submitted to Engineering Services will receive a preliminary review to make sure that they adequately address the minimum requirements of this manual and all applicable development requirements. Any such plans not meeting these requirements will be returned to the applicant or his designated contact person as unacceptable for review. 1-101 PLAN REVIEW FEES Engineering plan review fees are required separate from other department review fees. The plan review fee shall be paid at the time of submittal. The review process begins when payment of the plan review fee has been made. The permit fee shall be paid prior to the issuance of the permit. 1-102 PLAN CHECKLISTS The Engineering Service’s “Plan Review Checklists” are included in this publication (Appendix A) as a guide to help the engineer in the plan preparation process. The City recommends that these checklists be used by the engineer to help facilitate the plan review process. 1-103 PLAN APPROVAL Each sheet of the plans shall have the City of Marysville approval block located within or adjacent to the design engineer's title block. The plans shall be considered approved by the City when the ---PAGE BREAK--- 1-2 approval block on each sheet has been signed by the Engineering Services Staff. If at any time a significant error or omission is discovered, the City may withdraw approval and order the work stopped pending correction of the error. 1-104 ENGINEER'S REGISTRATION STAMP Engineering plans and/or calculations submitted for approval shall be stamped by a Washington State licensed professional engineer. 1-105 RIGHT-OF-WAY DEDICATIONS All required right-of-way dedications shall be recorded by Snohomish County prior to final plan approval. All easements shall be completed in a format to the City’s requirements. Easements for utilities shall be drafted and signed by the property owner and given to the City prior to final plan approval. Upon completion of the project, the original easement shall be modified, if necessary, and then recorded at the property owner’s expense. All such easements and dedications shall be clearly shown on the engineering plans. (See Appendix C for sample forms.) 1-106 ALTERNATIVE METHODS OR CONSTRUCTION MATERIALS REQUEST When circumstances warrant, the applicant may request to vary from the design standards set forth in this manual. The applicant should be aware that the City of Marysville design standards are considered minimum requirements. It will be up to the applicant to provide the justification for the request. The applicant shall submit a completed “Alternative Methods or Construction Materials Request” form to Engineering Services. The request will be reviewed by all applicable City departments. The final decision will be by the Engineering Service Manager. (See Appendix C for the “Alternative Methods or Construction Materials Request” form.) 1-107 VARIANCES A. Variances from these Standards may be granted by the Public Works Director or designee upon evidence that such variances are in the public interest and that requirements for safety, function, fire protection, appearance and maintainability based upon sound engineering judgment are fully met. Detailed procedures for requesting variances and appeals variance decisions are contained in the Marysville Municipal Code. Variances must be approved prior ---PAGE BREAK--- 1-3 to approval of the engineering plans for construction. Any anticipated variances from these Standards, which do not meet the Uniform Fire Code, shall also require concurrence by the Fire Marshal. B.
