Commissioners Present: d'Arcy Bosell, James Elling, Ralph Kishel, Jeannine Pyron Commissioner Absent: Gary Schwendinger Also Present: Rex Stockwell, City Engineer from T.K.D.A., and others Minutes of January 24, 1978 Correction: page 5 - 2nd paragraph - change "The Commissioners all agreed " to "Most of the Commissioners agreed. " Motion by Commissioner Bosell, seconded by Commissioner Elling, to approve the Minutes as amended. Motion carried unanimously. Cunningham Addition Preliminary Plat (Comm. #7-77-4) The Commissioners had received a letter (copy attached) dated 2-9-78 from Rex Stockwell of T.K.D.A. They discussed Ordinance 10 Sections 9.03 (p), 8.02 (f), 8.03 (c) and 8.04 (f) in relation to the plat. Also, that Lot 13 indicates 13,300 square feet of area but that isn't accurate; Crocus Street is indicated on the plat as "under construction" which is no longer true. Mr. Stockwell explained that the requirement of 8.03 (c) is not met in this type of plat until after preliminary approval because of the expense involved to the developer. The Coon Creek Watershed Board has sent a letter indicating their approval of the plat with the 50' easement along the ditch but the letter states nothing about approval of storm sewer drainage into the ditch. Mr. Stockwell said that when he presented the Northwoods Addition recently to the Watershed Board for approval of storm sewer drainage, he also included the possible additions of Cunningham and Creekside; therefore Mr. Stockwell assumed the Watershed Board had agreed to the Cunningham Addition runoff. He will contact the Engineering firm for the Coon Creek Watershed Board to get clarification and/or an opinion in writing. , ) \ V . ') 'J u '\ "j Planning and Zoning Commission Meeting Minutes - February 14, 1978 Page 2 The following items should be corrected: (1) type of surfacing and width of nearby streets should be shown (Ordinance 10, Sec. 8.02 (f)). (2) Crocus Street is shown on the plat as "Under Construction" with a gravel surface. (3) The square footage on Lot 13 should be changed. (4) Flood plain boundaries (Ordinance 10, Section 8.04 (f)). (5) Minimum basement elevations should be corrected. The Preliminary Plat of Cunningham Addition will be placed on the Agenda for continued discussion on February 27, 1978. Ogema Estates Revised Sketch Plan (Comm. #3-75-2) Ron Smith, the developer of Ogema Estates, presented a revised sketch plan to the Commission showing 129.2 acres with 37 lots. " \. ) Some of the suggested corrections to be made are: length of blocks - Section 9.05 (a) of Ordinance 10 requires 1320' maximum length; Lot 4, Block 6 and Lots 3 and 1 of Block 5 are undersized; radius on cul- de-sacs; Section 9.03 (e) - street jogs shall be 150+'; corner lots must be 15 feet wider than interior lots; Section 9.06 (f) double frontage lots; no dimension shown on South line of Lot 7, Block 5; l59th Avenue is indicated on the sketch as "Town Road". The Commissioners and Mr. Smith discussed 300' versus 330' m~n~mum lot frontages required and also some of the alternatives in planning the roads in the plat. Mr. Smith will attempt to redraw the sketch of the property to meet the requirements of Ordinance 10 and come back with another drawing. Gloria Aylmer Sketch Plan (Comm. #2-78-2) Gloria Aylmer wishes to divide her 20-acre parcel of land, with R-2 zoning, in Section 30, between 7th Avenue and Lipan Street, into 15 lots. The Commission noted that the streets should be 66' instead of the 50' as she has shown. Discussed Section 9.03 (g) - radius on the cul-de-sacs; l45th Lane should be aligned with the l45th Lane in Meadowood; corner lots must be 15' wider; double frontage lots. She was advised of the park dedication requirement. '\ , / \. ) / "J \J u "- I / Planning and Zoning Commission Meeting Minutes - February 14, 1978 Page 3 Trowbridge Sketch Plan (Comm. #2-78-1) Mr. Trowbridge called and said his sketch wasn't ready and he will call later to be on the Planning and Zoning Commission Agenda. Review of Ordinances (Comm. #6-77-6) The Commission briefly discussed the junkyard ordinance they are proposing, the December 20, 1977 City Council Minutes, whether any junkyard licenses have been issued,_and who has applied for a license. It was also noted that the 7th Day Adventist Church is operating a school without a special use permit. Adiournment Motion by Commissioner Elling, seconded by Commissioner Kishel, to adjourn.

The revised plat has resulted in a new street arrangement and a decrease in the number of lots to fuirteen. Other changes include: 1. Average lot size is in excess of 15,000 square feet. 2. Twenty foot radii have been included at the street intersection and cul-de-sac. 3. Right-of- Way width is 60 feet. 4. Lot depth of all lots is 130 feet minimum. 5. Utility and drainage easements have been provided along common lot lines of lots 1, 2 and 3 and 4, 6 and 7; 10 and 11; 11, 12 and 13; 10 and 13; and along the back line of lots 9 and 10. These easements were required for proper drainage control. 6. Street jog between 140th Lane N. W. and proposed 140th Circle N. W. is in excess of 150 feet. 7. A separate surface drainage plan has been provided. 8. Coon Creek Watershed has responded by letter. (Copy attached. ) 9.

The grading plan includes the addition of fill material to an elevation above the 100 year flood level. In addition to the above changes, the developer has provided five soil borings at locations shown on the soils map. The soils report outlines problem areas and suggests construction practices for homesites on several of the lots. Lots 8 and 9 and possibly 7 and 10 will require substantial peat removal while lot 1 will require some removal of black clay loam below any future footings. It is suggested that an additional boring be required on each of these lots just prior to cons truction of a res idential building. <) The soil borings also indicate the ground water level at each location. City ordinance requires that the minimuJTI basement floor elevation be at least 3 feet above the ground water level and the first floor elevation be at least 1. 5 feet above the street elevation. To conform to these requirements, the following minimum elevations are suggested: Minimum Basement Floor Elevation Minimum First Floor Elevation Lot 1 2 3 4 5 6 7 8 9 10 11 12 . 13 865.0 865.0 865.0 865.0 866.0 866.0 866.0 866.0 866.0 866.0 866.0 866.0 867.0 869.0 870.0 870.5 873.5 873. 5 872.0 871. 5 871.5 871.5 871. 5 872.0 873.5 875.0 ~ '---.J ' :J :~ , '\ \J o '0 "Planning and Zoning Commission .

Also plotted on the map are the boundaries of soil types identified by the Soil Conservation Service in their publication, Soil' Survey of Anoka County, Minnesota. As the map shows, the site is dominated by "Soderville fine sand, 0 to 4% slopes". with "Zirrunerman fine sand. 6 to 12% slopes" in the somewhat higher southeast corner. These two soil types are similar except that the Soderville has a higher water table. Along the west side the proposed subdivision has . "Rifle muck, woody" which is an organic soil and "Alluvial land, mixed. frequently flooded" which is a mixture of organic soils and sand. ',-~ <.J Ground water varied at the testholes from elevation 861.9 to 862.9 at testholes 1, 2 and 3 which were made in October, 1977 and from elevation 862.9 to just below 864 at testholes 4 and 5 which were made in January, 1978. At testhole number 4 we found indications that ground water has, at sometime in the past, been as high as elevation 867.1 feet. This is indicated by the mottled soil coloration at 1 foot. The drainage ditch along fhe west line of the proposed subdivision has now lowered ground water to the elevations presently indicated by testholes. In our opinion, basements for homes at this proposed subdivision should be constructed no lower than elevation 864. The soils data as reported herein indicates adequate foundation conditions for homes at each of the proposed lots at this subdivision except lots 8 and 9 and possibly lot 1. At lots 8 and 9 it should be expected that ten or more feet of unstable organic soil will pe encountered at the house locations as based upon our testhole number 5. Construction at these lots will require either replacement of the organic soil with compacted sand or the use of piles. 'At lot 1, testhole number 1 indicates that 5 feet of fill has been placed above the original topsoil, a black clay loam. Based upon testhole number 1, normal depth footings at this lot would be expected to reach adequate soil. The soil boundaries shown on the enclosed map however. ~J W~ .. .... ___ "...--n - . ) '-- f- '\ .\_--) ~J ~ "\ . U Mr. Jlm Hane , , , J \ , '-' Page 3 /- " - '\ . \ (. \. i '-./ , -February 6, 1978 indicate that soil conditions may be more unfavorable toward the west side of lot 1. We recommend that additional testholes should be made at lots 1, 8 and 9 prior to construction. Although less than adequate conditions were revealed by our testholes for lots 8 and 9 and possibly lot I, in our opinion the conditions are. not so unfavorable so as to recommed against platting of these lots. The,soil as observed will not affect the construction of utilities 'and curb and gutter at proposed 140th Circle N.W. Further it has been our experience that the special foundation requirements, such as will be required for lots 8 and 9 and possibly lot number I, are economically feasible as a part of the lot and construction costs for development of single family residential home:;. Although the proposed subdivision was found to have predominantly sand soils at the surface, clay soil materials were found at some locations within normal foundation depth. Under these conditions surface run off waters can become trapped adjacent to foundation walls creating a potential soil moisture problem in the house basements. Good construction practice such as positive ground slopes away from the houses and foundation water proofing should remedy these potential moisture problems. In more severe cases the use of footing drain tile should be considered. Yours truly, . HAKANSON, ANDERSON ASSOCIATES ~(, E, ~~ Carl E. Anderson P.E. CEA:kao r--,. ~ - - - - ~ ~--...-
