Excavation of the beds of public waters may be permitted except where; 1) it is intended to gain access to navigable water depths when such access can be attained by a dock: 2) inland excavation is intended solely to ~xtend riparian rights to non-riparian lands, or to promote delvelopment of non-riparian lands; or 3) the proposed excavation will be detrimental to fish or wildlife habitat or protected vegetation. The placement of structures in public waters is not permitted where the structure: 1) is intended to gain access to navigable water depths where such access can be attained by other means; 2) will...obstruct navigation and/or create a water safety hazard;or 3) will be detrimental to fish or wildlife habitat or protected vegeta- tion (prohibited in posted fish spawning areas). The construction or reconstruction of dams, or changing the level of an existing control structure may be permitted to: 1) control flood waters; 2) maintain low flows; 3) manage water quality, including the prevention and/or control of erosion and sedimentation, 4) improve water based recreation; 5) create,improve, and main- tain water supplies; and 6) maintain aquatic habitat for fish and wildlife species. The crossing of public waters, including the construction of water intakes a_nd sewer outfalls, may be permitted when less detrimental alternatives are unavail- able or unreasonable, such crossings will not be premitted where the project will: 1) obstruct navigation or create a water safety hazard; 2) cuase or contribute to increases in flood elevations and damages; 3) involve channelization greater than channel realignments to improve hydralic entrance/exit conditions; and 4) be de- trimental to water quality, fish or wildlife habitat, or protected vegetation. STATUS Currently Anoka County is in the process of reviewing the preliminary designations and mapping of the Cormnissioner which were received by the county on October 6, 1980. The county's 90 day review period expired on January 4, 1981. In resl~onse to the county's request for a one year extenslo , the Commissioner has granted the county an extension to June 1, 1981 (approximately a five month extension). Staff has reviewed the preliminary designations and mapping of the Commissioner of Natural Reseurces. In conducting this review, staff utilized information available from: 1/2 section aerial photos; soil maps; soil Conservation Service wetlands in- ventory; individual property owners; community officials, site investigations, county ditch records; and government lot surveys. As a result of the staff review a re- mapping has been undertaken. Before submission of the county's review and recommen- dations to the Department of Natural Resources, additional public informational meet- ings and review of staff recommendations and remapping by local units of government is deslrable. , ISSUES The public waters/wetlands designation and mapping is, in some respects, a type of zoning. Said designation, will impact on lend use, effect property values, and impair the sale of properties. For this reason 'very accurate designation and mapping.is needed. The preliminary designation and mapping for Anoka County is very inaccurate, and thus totally unusable, because extensive areas have been included which do not qualify as ~ublic waters or wetlands.
