<br />B. Topography and Water Drainage <br /> <br />The glaciers helped form the current land surface of Roseville. More than 10,000 <br />years ago, Roseville evolved into a series of bluffs and upland hills which also <br />define the adjacent lowlands - a network of drainage ways, lakes and marshes. The <br />topography of northern Ramsey County (and Roseville) is irregular with ground <br />elevations varying approximately 150 feet: from 1,000 feet above Mean Sea Level <br />(MSL) near County Road B-2 and Western Avenue to a low of 840 feet above MSL <br />south of McCarron's Lake. Because of this topographic change, the City of <br />Roseville lies within three major drainage districts: Rice Creek Watershed District <br />in the western portion of the City, Grass Lake Watershed Management <br />Organization in the northeastern portion of the City, and the Capital Region <br />Watershed District in the southeastern portion of the City (See Watershed Districts <br />Map) <br /> <br />Natural water features within the City include McCarron's Lake, Lake Owasso, and <br />Lake Josephine. There are other significant water areas within the City which <br />include Zimmerman Pond, Bennett Lake, Walsh Lake, and Langton Lake. The City <br />has numerous ponding easements which are utilized as part of the City's storm <br />water drainage system for retention of storm water. The significance of the system <br />of water drainage is discussed in the section on storm water sewer systems. <br /> <br />C. Soils <br /> <br />The Ramsey County Soil Conservation Service has identified the following general <br />soil types within the City of Roseville. (See General Soils Map) <br /> <br />Hayden: This soil type is a fine sandy loam with level to steep slopes, moderate <br />permeability and high available water capacity. Natural fertility is medium and <br />organic matter content is low. This soil is well suited for urban landscape plantings <br />and for building. Potential for frost heave is moderate. <br /> <br />Chetek: This soil type is a sandy loam found with level to steep slopes, high <br />permeability and has a high potential for erosion. This soil has fair potential for <br />urban landscape plantings, establishing turf may be a problem due to its low water <br />capacity. This soil is well suited for building site development. <br /> <br />Zimmerman: This soil type is a loamy fine sand, level to moderately sloping and is <br />excessively drained and has low water capacity. Natural fertility is low in this soil <br />type as well as low organic matter. These soils have fair suitability for urban <br />landscape plantings and are well suited for building. <br /> <br />Roseville Comprehensive Plan - 2002 Update <br />. . <br /> <br />The Land and its People - Page 5 of30 <br />
