City of Ramsey -3- 10/15/85 Certificates would be grouped by type of property; i.e., residential or commercial; improved or unimproved, etc. Each transfer report would be located according to an overall coordinate system to facilitate computer- ized grouping by distance ring and directional sector. This would also facilitate analysis of the data base using different centers within the City of Ramsey or adjacent areas of coverage. This will explore the possibility that development timing, property values, or other variables which correlate with value change are predetermined by landfill location. The study will also identify other major contributing factors that offset Ramsey property values. We will not statistically analyze those factors. However, it is important that in establishing study credibility that all factors are recognized. Paragraph C - Impact of Potential Water Pollution Paragraph C will be answered by having the ground water hydrologist, Mr. Jerry Briggs of our consulting team, prepare a water supply and distribution scheme for the City assuming the Landfill does not exist. Given the Landfill's existence, we will also have our hydrologist prepare a precautionary water system plan. Given the possibility of ground water pollution, the hydrologist will also suggest possible alternate responses to such occurrence. To estimate the impact of potential pollution problems relating to the ground water resource in the City of Ramsey, a study of a number of factors is required. These include geology of the area, hydrology of the area, permeability of the water-bearing strata, recharge from precipita- tion, present quality of the ground water, quantity of ground water being pumped and to be pumped, hazard of seepage from the sanitary landfill. To accomplish the task, we will make a study of the geology of Ramsey and adjacent townships. This would include known facts and deductions that can be made from available well logs from several sources. Basically, the City of Ramsey is located on what is known as the Anoka Sand Plain. The top stratum of the underlying geologic formations consists of outwash sand, silt, and gravel from a glacier which stopped its movement north of this area and discharged sand and gravel by water flow from the melting of the glacier. A previous glacier left a layer of till (clay) on top of the under- lying sandstone. This till is covered by outwash sediments which cover the underlying clay some 15 to 60 feet thick. Shallow wells capture ground water from these sediments where the well is drilled to some depth below the water table. Below the upperglacial deposit, a series of strata of sandstone is found, some of which are valuable sources of ground water. The sandstone strata are known as the St. Laurence formation, the Franconian formation, and the Galesville-Ironton formation. All are saturaged with ground water, but some parts of each of these formations may be of low permeability, and will only yield small amounts of water to wells.
