General Information CASE: Sensitive Lands Permit (SL 9-85) REQUEST: To allow for the placement of fill and overflow channel improvements within the 100-year flood plain. COMPREHENSIVE PLAN DESIGNATION: Light Industrial ZONING DESIGNATION: I-P (Industrial Park) APPLICANT: Mr. & Mrs. George Koeber OWNER: same Mr. r, Mrs. Gale Nelson 6700 6tk ;.11th Ave. Beaverton, OR 97005 LOCATION: 14865 SW 74th Ave. (WCTM 2S1 12AC, T.L. 900 and 1200) 2. Background No other land use proposals have been reviewed by the City regarding this property . 3. Vicinity Information The properties to the north and south are also zoned I-P. Seventy-fourth Avenue and the Burlington Northern Railroad tracks lie to the east and residentially zoned parcels (R-7 and R-12) arG directly Ywest. 4. Site Information The property is presently undeveloped and predominantly wooded. Fanny, Creak meanders in and out of the parcel near the western property line and Ball Creek crosses the northern half of the parcel from 74th Avenue to its confluence with Fanno Creek . The 100-year flood plain elevation in the immediate area is 135 feet. STAFF REPORT - Si 9-65 - PAGE 1 1 t The applicant proposes to place fill within the 100-year flood plain to create one building site on each side of Ball Creek. An area of . t approximately 140 feet in width will be left in its natural state on each side of Ball Creek. The channels for both creeks will not be altere ', however, an overflow channel is proposed for Fanno Creek to compensate for the f:ll. 5. Agency and NPO Comments The Engineering Division has the following comments: a, Because a sewer trunk line controlled by U.S.A. is located in the vicinity of the proposed overflow channel, U.S.A. should be given an opportunity to review this proposal prior to construction. • b. Fill and excavation work should not occur between October 1st and April 30th because of potential erosion or flooding problems . c. A hydrologic study prepared by a registered engineer including cross sections and an analysis of the backwater curve at high and low flows should be submitted for review before the issuance of permits. d. A geotechnical report prepared by a soils engineer will be necessary relating to the landfill areas prior to issuing building permits. e. The necessary approvals must be obtained from tie Division of • State Lands and the U.S. Army Corps of Engineers. The Building Inspection Division indicates that a civil engineer should be involved to ensure the suitability of the fill, areas for building construction. Tualatin Rural Fire Protection District has no objection to the proposal but notes that further review will be necessary when specific plans for the warehouse and office building are formulated. NPO #5 has no objection to the application provided that all engineering requirements related to Sensitive Lands approval are followed and that the developer retain as many Douglas fir trees as possible. B. FINDINGS AND CONCLUSIONS Section 18.84.040 of the Community Development Code contains six criteria that must be addressed in order to approve a request within the 100-year flood plain. 1 . Land form alterations shall preserve or enhance the flood plain storage function and maintenance of the zero-foot rise floodway shall not result in any narrowing of the floodway boundary. 2. The land form alteration or development within the 1t3O-year flood plain shall be allowed only in an area designated i cornmerci,sl or industrial on the Comprehensive Plan Land Use Map. STAFF REPORT - SL 9-85 -- PAGE 2 3. The land form alteration or development is not located within the floodway. 4. The land form alteration or development will not result in any increase in the elevation of the zero-foot rise floodway. 5. The land form alteration or development plan includes a pedestrian/bicycle pathway in accordance with the adopted pedestrian/bicycle pathway plan. 6. The plans for the pedestrian/bicycle pathway indicate that no pathway will be below the elevation of an average annual flood. Although some additional information will be necessary, the Engineering division is satisfied that no encroachment or development will occur •• within the zero-foot rise floodway . The property is zoned I-P and this • proposed land form alteration is appropriate. The proposed grading plan will allow for the installation of a bicycle/pedestrian path at a later date. The City has not required the installation of the path when it would represent an isolated segment without any legal access. The City has a policy of requiring the dedication of the Fanno Creek flood plain for open space purposes. In commercial and industrial zones, the City requires the dedication of all land which remains within the 100-year flood plain after a plan for modifying the flood plain boundary is approved. Policy 3 .2.3 of the Tigard Comprehensive Plan supports this greenway dedication requirements. C. RECOMMENDATION Based upon findings and conclusions noted above, the Planning staff recommends approval of SL 9-85 subject to the following conditions: 1 . Construction of the proposed channel and site earthmoving shall not commence until after the Engineering Division has issued approved public improvement plans. The Division will require posting of a 100% Performance Bond and the payment of a permit fee.
