No. 5) and State Trunk Highway No. 47 in accordance with the standards for municipal state aid streets {MSAS). The location of the proposed street improvement is shown on Exhibit A. EXISTING CONDITIONS: Presently 167th Avenue N.W. consists of a rural street section. The street section consists of a bituminous pavement §enerally 24 feet in width with variable gravel shoulders. The right-of-way is 66 feet wide. The existing pavement is deteriorating and is proposed to be replaced. The street presently has adequate drainage with the West end of the street draining to the C.S.A.H. No. 5 ditch and the East end draining to the S.T.H. No. 47 ditch. The center portion of the street drains southerly into the open area lying South of the Klemish Addition. A sub-surface investigation was performed to determine the nature of the soils below the existing street. A copy of the text of that report is attached for your refer- ence. The soils investigation shows that the street generally consists of 3 inches of asphaltic concrete underlain by silty sand and silty clay. Several areas of the roadway were found to be underlain by frost susceptible and slightly organic soils. These soils are proposed to be removed as a part of the project due to their unsuit- ability as a supporting layer for the proposed street. PROPOSED IMPROVEMENT: 167th Avenue N.W. is proposed to be constructed to MSAS standards. The ultimate improvement would provide for a bituminous surfaced rural street section. The improvement would require acquisition of 14 feet of right-of-way to increase the existing right-of-way from 66 feet to 80 feet. In addition to the permanent right- of-way, slope easements would also be required for a portion of the project. Tree removal is also anticipated since the proposed street section width exceeds the present street width.
