1 MINUTES OF THE DANE COUNTY BOARD OF ADJUSTMENT MEETING OF SEPTEMBER 7, 1977 PRESENT: Erickson, Dahlk, Voges ALSO PRESENT: Fleck. . i The Board met at 1:30 P.M. in Room #314, City-County Building to act on appeal #590; Robert Aberg, Town of Dunn, held in abeyance from the public hearing of August 19, 1977. The meeting was called to order by Chairman Erickson and the finding of fact was read: 2 1. Board of Adjustment q Adjustment jurisdiction extends 300 feet North and South i of Swan Creek. 3 2. Natural swale on West side of Aberg property and South of Swan Creek already contains and controls surface water between Lalor Road and the Aberg Property. This water is diverted North to Swan Creek on the up- stream side of proposed road. Therefore, proposed road fill will not affect this drainage or be affected by it. 3. Terrain North of Swan Creek slopes upward from elevation of 850' , minus, (USGS) to above 900' and runs parallel (more or less) to Swan Creek. Surface drainage is Southward or at 90° ± angle to Swan Creek. Proposed road is also at 90° angle with creek and therefore will not obstruct surface flow nor be unduly affected by the surface flow. 4. Diking affect of proposed road and susceptibility to washing (sedi- mendation) will be minimal because of the existing natural swale men- ii tioned in 2. above and the normal flow of surface water from the North flowing South to the creek in the same (more or less) direction as the proposed road. There would not be a necessity for any surface water Ir; from the North to cross the proposed road. i 5. Drainage to the East of proposed road will not be affected. 6. The scientific area located at the Southeast corner of the Aberg property is protected by high ground between the proposed road and the scientific area. Surface flow from proposed road area will not reach the scientific area. 7. Water table should not be affected because of minimal affect of proposed road on drainage pattern of area. The existing berm ex- plained by Mr. Calvin DeWitt at the public hearing as causing a drop in water table, lays parallel to the creek and therefore across the normal drainage flow. The proposed road would not have this affect. See #2, 3 and 4 above. ii 8. Opening or culvert in stream bed will be approximately two times the size of the existing culvert under Lalor Road. Bridges, culverts, etc. , placed in stream bed are subject to Department of Natural Re- sources approval and specifications and do not require Dane County i Board of Adjustment approval. o 9. Development of area is not the question before the Board. Develop- ment of area is under jurisdiction of the Dane County Subdivision and k Zoning Ordinances. g 6 Motion by Voges second by Dahlk to grant the Special Exception, as pro- posed, with the conclusion that the proposed fill for road will not ad- versely affect erosion, sedimentation, or safe and healthful conditions. !' Motion carried unanimously. Motion by Voges, second by Dahlk to adjoin 41: meeting. The meeting was adjourned. Harland Dahlk, Secretary fi). y
