floodplain administrator may require that the applicant provide data derived by standard engineering methods. The applicant representative, Kyle Latimer of Udell Engineering, submitted an elevation certificate based on construction drawings that show the base flood elevation at the site of the proposed home location is 230.8’ (NGVD29). The property is designated Zone AE and shown on panel 41047C1000G. The criterion is met. C. Prior to obtaining a building permit the owner shall be required to sign and record in the deed records for the county a declaratory statement binding the landowner, and the landowner’s successors in interest, acknowledging that the property and the approved development are located in a floodplain. The signing of a declaratory statement will still be made a condition of approval. D. Prior to obtaining a building permit, commencing development or placing fill in the floodplain the applicant shall submit a certification from a registered civil engineer demonstrating that a development or fill will not result in an increase in floodplain area on other properties and will not result in an increase in erosive velocity of the stream that may cause channel scouring or reduce slope stability downstream of the development or fill. The applicant shall provide evidence in the form of engineer certification that the proposed manufactured home placement complies with this criterion as a condition of approval. E. The applicant shall provide an elevation certificate signed by a licensed surveyor or civil engineer certifying that the actual elevations (in relation to mean sea level) of the lowest floor (including basement) and all attendant utilities of all new or substantially improved residential structures including manufactured dwellings meet the requirements of MCC 17.178.060(A), (B) and (C), where applicable, as follows: 1. Prior to construction (based on construction drawings); and 2. Once the floor elevation can be determined (based on the building under construction); and 3. Prior to occupancy (based on finished construction). This proposal is for a residential structure, the applicant shall submit an elevation certificate at the times listed above. The first elevation certification, based on construction drawings, was submitted with this application. Submission of the subsequent elevation certificates shall be a condition of approval. 10. MCC chapter 17.178.060 A, & D-H pertain to this project. A. Residential Structures, Including Manufactured Dwellings and Related Structures. New residential construction, substantial improvement of any residential structures, location of a manufactured dwelling on a lot or in a manufactured dwelling park or park expansion shall: 2. Manufactured dwellings shall have the bottom of the longitudinal chassis frame beam, including basement, elevated on a permanent foundation to two feet above base flood elevation. Where the base flood elevation is not available, the finished floor, including basement, shall be elevated on a permanent foundation to two feet above highest adjacent natural grade (within five feet) of the building site; The application materials show that the proposed manufactured home will be elevated so that the bottom of the longitudinal chassis shall be at least 2’ above the BFE. Final confirmation by way of an elevation certificate shall be a condition of approval. 3. Manufactured dwellings shall be anchored in accordance with subsection (D) of this section; and all electrical crossover connections shall be a minimum of one foot above the base flood elevation;
