The street was placed in conjunction with sewer and water <br />facilities in 1979. The existing street section consists of 6" of granular base and 2" of bituminous <br />material and is 30 feet wide. <br />The existing street section is inadequate for the conveyance of projected traffic loadings. <br />The existing 300 foot portion of Desoto Street will be removed and replaced with the proposed <br />street section. <br />The proposed street design consists of the following street section: <br />1 -1/2 inches - 2341 Bituminous Wear Course <br />1 -1/2 inches - 2331 Bituminous Base Course <br />8 inches - Class 5 Aggregate Base, 100% Crushed <br />This section is a typical section for a 7 ton residential street of moderate residential traffic. <br />the proposed street section for Desoto Street is illustrated on Figure No. 2. <br />Soil borings were taken within the development area. The soil consultant indicated in his <br />report that the subsurface soils are considered to be marginally suitable for normal street <br />construction. Sandy loam clays with water - bearing sand lenses were encountered just below the <br />ground surface at locations where Desoto Street is to be placed. These soils are very frost <br />susceptible and lack stability. Therefore it becomes necessary to dewater the subgrade and to <br />provide a boundary to promote separation of the subgrade from the street section. <br />37207.RPT <br />4. <br />Page 68 <br />
