City of Mounds View Comprehensive Plan <br />______________________________________________________________________________ <br /> <br /> <br />12 <br />Wetlands and Drainage <br /> <br />Wetlands and ponding areas serve as holding areas for storm runoff, filter ground water supplies, <br />and provide habitat areas for wildlife. Wetlands have been protected, for the most part, as Mounds <br />View has developed. Mounds View has wetland protection and flood plain regulations in place. The <br />City of Mounds View also works cooperatively with Rice Creek Watershed District to ensure that <br />development does not adversely affect wetlands and drainage. Figure 1 on page 13 generally shows <br />the existing wetlands in the community. <br /> <br />Figure 2 on page 14 illustrates the six city drainage districts that have been designated. District <br />boundaries were determined by the direction of drainage flow and the watercourse the drainage <br />flows to. Drainage systems include ditches, drainageways, and storm sewers. Storm water problems <br />are limited to some local trouble spots. There is no need for major expansion or major alteration to <br />the current system. New development will be reviewed to ensure that the current system is not <br />adversely affected. <br /> <br />Soils <br /> <br />The majority of the soils present in Mounds View offer slight to moderate limitations to <br />development. Potential development limitations are shown in Table 1 below and Figure 3 on page <br />15. <br /> <br />TABLE 1: Soil Limitations <br /> <br />Soil Type Description Slight Moderate Severe <br /> Limitation Limitation Limitation <br />158 B,C,D: Zimmerman Well drained loamy fine sand X <br />161: Isanti Poorly drained loamy fine sand X <br />162: Lino Somewhat poorly drained loamy fine sand X <br />265: Soderville Somewhat poorly drained loamy fine sand X <br />540: Seelyville Muck Very poorly drained muck X <br />543: Markey Muck Very poorly drained muck X <br />859 B: Urban Land-Zimmerman Complex Excessively drained loamy fine sand X <br />863: Urban Land-Lino Complex Somewhat poorly drained loamy fine sand X <br />1027: Udorthents, Wet Substratum Heterogeneous earthy fill material X <br />1039: Urban Land Developed areas with 90% impervious surface X <br />1055: Aquolls and Histosols, Ponded Very poorly drained mineral and organic soils X <br />Source: Ramsey County Soil Survey <br />
