Coon Rapids/Andover This proposed sanitary landfill site is located south of County Rd. 116 and adjacent to Bunker Hills Regional Park. There is some residential and indus- trial development to the west and south of the site. Access is excellent. Underlying soils are highly permeable and do not protect surficial groundwater; however, the double liner and leachate collection system proposed by the county should adequately compensate for the lack of impermeable soils. East Bethel (Site This proposed sanitary landfill site is south of County Rd. 75. The East Bethel Landfill adjoins the site, as does Booster Park and East Bethel's pro- posed "downtown" district, Most residential development occurs to the north and east of the site. Access to Site E is good. Soils on the site are highly permeable and do not protect the surficial groundwater, and a Type III wetland exists in the buffer area. Furthermore, there is some evidence that not ail groundwater flows toward the wetlands and Neds Lake, which are south of the site. More study of .the groundwater flow regime in this area"~s needed. RamseS This proposed sanitary landfill site is south of the Anoka Municipal Landfill and west of County Rd. 57. Access to the site is excellent. There is resi- dential development, primarily on one-'acre lots, to the northwest and southeast of the site. Comercial and industrial uses occur to the south and west. A Type III wetland is just west of the site. The site has highly permeable soils that do not protect surficial groundwater; however, the double liner and leachate collection system the county has proposed should adequately protect groundwater resources. Oak Grove Township. This proposed sanitary landfill site is about 200 feet west of Martin St. and 500 feet north of Cedar Creek, The Oak Grove Landfill is in the western buffer area and about 90 residences are within one mile of the site. Access is good. There are tamarack and hardwood swamps just south of the site. Under- lying soils are highly permeable and do not protect surficial groundwatera In addition, there is a chance that future residential development northeast of the site could change the direction of groundwater flow away from the discharge area to the south. More study is needed to evaluate the implications of residential development on the groundwater flow regime.
