by the wetland mitigation site was 14.93 acre -feet. A calculation of remaining floodplain storage is provided below: 14.93 Ac -Ft Total additional volume created by wetland mitigation in 1998 — 9.86 Ac -Ft Total floodplain fill from 1998 Otter Lake Road project — 3.69 Ac -Ft Total floodplain fill currently proposed by Arnt Construction = 1.38 Ac -Ft Remaining excess floodplain storage volume This demonstrates that the floodplain system in this stretch of Clearwater Creek has the ability to handle the temporary fill proposed by Arnt Construction Company, Inc. The RCWD does not operate a floodplain volume banking program, nor does it intend to create one. Additionally, the City of Lino Lakes, not Arnt Construction, was the original permitee for the Otter Lake Road Project when the excess floodplain storage was created. Considering the interim nature of the approval being considered by the City of Lino Lakes, the RCWD is willing and proposes to accept this demonstration of available floodplain storage volume to facilitate the proposed temporary project. Due to past project history in this location, however, we feel concurrence by the City of Lino Lakes is essential. If the City agrees, no additional permitting would be required by the RCWD for this project. If the City is not comfortable allocating the floodplain "credit" from its previous Otter Lake Road relocation project as proposed herein, the applicant would then be required to obtain a RCWD permit and construct appropriate floodplain mitigation onsite. If permanent floodplain fill becomes a part of any plan at this location, those plans would be again subject to RCWD review and approval through our standard permitting procedures. If you have any additional questions or concerns about this proposal, please contact me directly at (763) 398 -3072 or kaxtell @ricecreek.org. Please provide a written response detailing the City's opinion regarding this proposal. If approved, also please provide us with a copy of the issued interim land use permit for our records. e Axteli Water Resource Specialist CC: Nicholas Arnt — Arnt Construction Company, Inc.
