a source of lead in the residential water supply and the cast iron pipes are probably <br />heavily corroded and possibly leaking. <br />3.3. Storm Sewer <br />There is an existing 18 -inch reinforced concrete pipe (RCP) storm line on 39th Avenue <br />NE running from Penrod Lane to Shamrock Drive. A 24 -inch RCP storm main joins the <br />system from the south and a 15 -inch RCP joins the system from the north at Shamrock <br />Drive. The main in 3 9th Avenue NE becomes a 3 0 -inch RCP at that point and continues <br />east to Fordham Drive. It then turns southeast under the railroad to Chandler.. <br />There is very limited storm sewer in the southern section of this project. The alley south <br />of 27th Avenue NE has a 15 -inch reinforced concrete pipe (RCP) storm line which drains <br />an existing low point approximately one-third of the way in from the west end. Twenty- <br />seventh (27th) Avenue NE and Pahl Avenue each only have existing catch basins at their <br />east ends at the intersection with Wilson Street. There is no existing storm sewer in <br />either of the other alleys. <br />3.4. Streets <br />Thirty-ninth (39th) Avenue, Pahl Avenue, and 27th Avenue NE are generally 30 -foot wide <br />streets with concrete curb and gutter. Roosevelt Street is generally a 22 -foot wide street <br />with concrete curb and gutter. The alleys are all 12 -feet wide bituminous pavement with <br />no concrete curb or gutter. No borings have been taken for these streets, but other soil <br />borings on adjacent streets indicate that there is approximately 5 inches of bituminous <br />over 2.5 feet of silty sand fill. Soil borings have been ordered and will be included in the <br />Appendix if available at the time this report is completed. <br />a <br />4. PROPOSED IMPROVEMENTI <br />4.1.
