Raatikka, P.E. Hay 22, 1986 Honorable Mayor & City Council City of Ramsey 15153 Nowthen Boulevard N.W. Ramsey, MN 55303 Re: 1986 Seal Coating Projects Dear Council Members: In response to comments received at the seal coating public hearings in regard to the street conditions, Mr. Merle Mevissen and myself recently reviewed the areas proposed for seal coatings. The area with the most repair work required prior to seal coating was the Riverwood Hills unplatted area. Five areas in that development will need reconstruction or an overlay. The other area requiring other than minor repairs was the Hall Anderson Acres plat which had three areas in need of reconstruction. The other project areas will require only minor patching and crack filling. Mr. Mevissen has estimated the cost of the repairs in the Riverwood Hills unplatted area and the Hall Anderson acres plat to be $5,000. The City's Public Works Department has started to make the repairs and will complete the repairs prior to seal coating. I have also reviewed the cost differential in using FA-2 (pea rock) aggregate vs. FA-3 (crushed granite). The cost for using granite is approximately 50 percent higher than the pea rock. The estimated life of granite is 30 percent longer than pea rock. Therefore, based on a cost to benefit ratio, I would not recommend the use of crushed granite for a seal coat aggregate. In addition, the use of crushed granite is intended for use in high volume traffic areas and main highways. civil · municipal · planning · soils · land survo'ing · landscape architecture
