She introduced the City's consultants, Mr. John Shardlow, Mr. Ron Peterson and Ms. Lynn Rabuse. Chairman Stulberg asked that full terminology be used rather than initials during the discussion. Planning Supervisor Senness discussed a.memo that was passed out titled "Why Protect Wetlands". She said that the inventory will be the first step to determine what kind of wetlands are present and how development could be affected. She discussed the Geographic Information System (GIS) work which was recently done. She said the inventory will help update the wetland map currently in the GIS: Mr. Shardlow discussed some of the terms being used and their components. He said that they will give examples of other ordinances being used by other cities, as well as the locations and functions of the different types of wetlands. He said this will be a two-tier process which will include the use of aerial photographs. He showed their progress so far on a map indicating that the yellow portion of map has already been completed and the orange portion of the map has been field verified. a 0 a Planning CommissionMinutes J111y'20, 1994 Page 140 Mr. Shardlow discussed his handout including definitions of wetland types, what happens at the back of a lot with wetlands, and variables such as whether a buffer will be used. He said that the size of a wetland will need to be determined as far as what will be considered the minimum size. He discussed the ordinances adopted by the communities of Chanhassen and Maple Grove. Commissioner Black stated that Maple Grove used the WIOM, Wisconsin Rapid Assessment Method, in developing theirordinance. Mr. Peterson passed out field maps which they are still working on for review by staff, the Commissioners and the public. He said they will cross-reference aerial photos with soil maps from the Soil Conservation Service, and with National Wetland Inventory Maps. He said that they should be finishing the field work within a week and a half. Mr. Peterson passed out methodology worksheets and discussed the process they will use to evaluate the wetlands. He said that actual soil samples on individual sites will be taken at the time of propos: d development. Commissioner Albro asked if soil samples would be necessary in order to classify the wetlands. Mr. Peterson responded that soils are not used for an indicator. He said they use the Hennepin County Soil Maps from 1977. Commissioner Albro asked if other issues such as regulation of chemicals could be used to preserve wetlands rather than setbacks. He asked what could be done to determine the present condition of a wetland. Mr. Peterson responded that ultimately these issues will be addressed at a later stage. He said that some areas may have soil samples done if there are questions. Commissioner Albro asked if natural versus manicured buffer areas will be looked at as well as sheet flow through a buffer area, and the use of Plantings that would absorb the water. He said that Chanhassen seems to have used plantings that absorb in their plan. Mr. Shardlow responded that these issues will be looked at. Mr. Peterson stated that some special features that will be looked at are characteristics that fails into the unusual category such as plants, wildlife, and vegetation. Planning Supervisor Senness stated she and Director Moore picked out the wetlands that fit into many categories for examination: 0 Planning Commission Nnutes. July 2e, 1994. Page 141 Commissioner Black asked how yes and no answers would be translated from the survey form into information to determine wetland types. Mr. Peterson responded that this will be based on professional judgment, and possibly assigning numerical data for the assessment. He said they will later pick out some samples to verify their decisions. He said this will depend on the weighting of different categories once this has been determined. Commissioner Black asked if they have looked at how the Open Space Committee and this study mesh. Mr. Peterson stated that this study will be done without any outside influence. When it is completed they can look at how the two mesh. Planning Supervisor Senness stated that the Open Space Committee is looking at all natural resources and that this study is just on wetlands. Mr. Shardlow stated that the changes in the Zoning ordinance will be based on findings of wetlands on property. He said there will always be the opportunity for a landowner to bring more complete information about a wetland on their property to theCity, Commissioner Albro asked if significant variations are found would it not be prudent to look closer at all areas. Mr. Peterson stated that they use visible characteristics and the surrounding landscape for their determinations. He said that springs are not found in Plymouth, Chairman Stulberg stated that if an area is fully developed there would be. less that could be done as ,far as setbacks from wetland. He asked what additional regulations could be adopted to make developed areas protect the wetlands, Mr. Peterson stated that abouthalf of the delineated wetland areas developed in the last Year were suggested by staff to be reviewed. He said that in their observation they found high quality wetlands with some degradation. He said quite a few will be in the high value category. Commissioner Albro what percent of the wetlands; will be visited, He said that the undeveloped areas should be looked at. Mr. Peterson responded that they will physically visit about 30 percent of the wetlands. Chairman Stulberg stated that he will be most Concerned with the high quality wetlands, a' Planning Commission Minutes July 20, 1994 Page 142 Planning Supervisor Senness stated that at the point of development the wetlands on all sites will be examined more closely. Commissioner Albro stated that he was interested in knowing how the tax roles will be affected and said his priority would be to protect the high quality wetlands to.a greater degree than those less desirable. Mr. Shardlow stated that the impact cannot be predicted until all information is gathered. Mr. Peterson stated that they should be done gathering information by August 3. Ms. Rabuse discussed the GIS Mapping and Analysis process. She discussed the data base and the information included and, the possibility of a weighting system. She said this information could be used to track how wetlands change over time. Chairman Stulberg asked if the data base could project what the land would look like in the future, depending on setbacks and other variables. Rabuse stated that a variable buffer and setbacks will be assigned to see what happens under various scenarios., She said they will also include the land use and zoning in the data base. Planning Supervisor Senness discussed the revised schedule. She said the next meeting for discussion of the wetlands will be the August 10 Planning Commission meeting. Chairman Stulberg called a recess at 8:25 p.m.; the meeting reconvened at 8:35 p.m. Chairman Stulberg asked if the audience had any questions. There were none. Commissioner Black stated that the issue of tax dollars lost should be turned around and looked at as tax dollars gained by saving the wetlands. She said we need to look at wetlands as an amenity. She asked what the size of buffer zones would be based on. Mr. Peterson stated that they will look at other ordinances and they are collecting other information on buffer zones and wildlife. Planning Supervisor Senness staled that all information gathered by staff to date, from public meetings and other sources, has been given to the consultants. Commissioner Ribbe asked what the purpose is of analyzing soil conditions. a Planning Commission Minutes July 20, 1994 Page 143 Mr.. Peterson responded that when delineating a wetland they look at the type of solifound. He said the SCS maps are based on soil samples. Commissioner Ribbe stated that these maps are 17 years old. Mr. Peterson stated that plant types can change but soil types do not change. Commissioner Ribbe stated that when a site has been graded then the soil has changed. Mr. Peterson stated that it becomes difficult to determine the soil type once the site isgraded. Commissioner Stimson asked if wetland ordinances of other cities are being looked at. Mr. Shardlow stated there are others in Ramsey and Washington County. He said thattheCityofPlymouthisattheforefrontintheirresearchonwetlands. He said they arelookingatnationalinformationaswellaslocal. He said past studies had to do withstormwaterdrainage.
