4.3. SR 11-21-1994 rei -\j ( )j Irk ITEM 4.3. MEMORANDUM TO: MAYOR & CITY COUNCIL FROM: PAT KLAERS, CITY ADMI,,~TOR DATE: NOVEMBER 7, 1994 ~ SUBJECT: REQUEST TO PURCHASE WESTERN AREA TOPOGRAPHICAL MAPS e Surface Water Management projects and storm sewer utilities have been planned and installed in the past on a project by project basis with just a generalized overall concept guiding the improvements. With the opening up of our City engineering policy to allow other engineering fIrms to do plans and specifIcations for public improvements in the urban district, it is necessary for the City to do much more detailed, long range planning in the storm water management area. In order to do more detailed long range plans, the City needs better base data to make logical assumptions and good planning decisions. We have not had good data in the past, and the City Engineer, in his attached material, is suggesting that the City obtain two foot topographical maps for the western urban area of the City. The fee for this project would be paid from the Storm Water Management Fund. I do not believe that we would recapture over half of these expenditures, but certainly some of this expense could be recaptured through our work with land developers. Staff is recommending this purchase in order to facilitate our planning efforts in the western area. e P.O.

Box 490 Elk River, MN 55330 RE: WESTERN AREA FUTURE STORM SEWER Dear Mr. Klaers: With all the recent discussions relative to storm sewer in the Western Area of the City, we have taken the liberty of contacting Markhurd relative to getting two-foot aerial topography for the undeveloped portions of the Western Area. We believe it would be appropriate for the City to take a proactive approach to future storm sewer construction in this area and develop a much more detailed plan as to the methods of storm sewering the remainder of the Western Area. Two-foot contours would be an absolute necessity to come up with a detailed plan for this type of work. As you can see from the quotation from Markhurd, the total cost of this mapping would be between $6,000 and $6,800. In addition to Markhurd's charges, there would be the necessity of providing them with vertical and horizontal controls from which to prepare their mapping. Their proposal indicates a total of approximately 20 points would have to be located. Not knowing exactly where these points are, we would estimate the total survey crew time at approximately $2,500 to $3,500 to accomplish this. Therefore, the total cost to acquire mapping of the remainder of the undeveloped area in the western part of the City would be approximately $10,000. The City could likely recover at least a portion, if not all, of this money by selling the topography back to Developers as various parts of this area are 1326 Energy Park Drive platted.

In the future, I would like to make the same recommendation for the East Trunk Highway 10 corridor, as that area gets closer to development. e Mr. Pat Klaers October 10, 1994 Page Two If you have any questions or would like additional information regarding this, please call.

MINNEAPOLIS/MAPLE GROVE, MINNESOTA SS369 TELEPHONE: (612) 420-9606 . FAX: IN REPLY, REFER TO: E8754 September 27, 1994 Mr. Mark Graham MSA 1326 Energy Park Dr. St. Paul, MN 55108 Dear Mr. Graham: Reference is made to your facsimile of September 23rd, and to our related telephone conversation. Accordingly, we are pleased to furnish our proposal for aerial survey services in portions of Sections 31, 32, 5 and 6, in Elk River, MN. Details are described below. e Area Our understanding of the area is indicated in red on the attached USGS map print. We have shaded in blue an area for which 2' C.I. topo mapping already exists, performed for Emmerich Builders. We have provided you with cost options including or excluding this blue area. Please examine these limits carefully, and unless changes are indicated on the prints returned with the acceptance copy of this proposal, we will understand the limits are correct. Aerial Photography We will use aerial photography taken on April 26, 1993, with a precision mapping camera. Map content will be as of that date. Negative scale of this photography is approximately 1" = 833', and is suitable for producing the 2' C.I. mapping requested. Ground Control It is understood that MSA forces will furnish the necessary control for mapping. We will furnish you with a set of new aerial photographs indicating the location and description of the points for which we require horizontal coordinates and vertical elevations. We e estimate -=i: 6-8 horizontal and -=i: 12 vertical points will be required. e e e " JfIIARKHURD Topographic Mapping We will digitally collect planimetric and Digital Terrain Modeling (DTM) data for a designed scale of 1" = 100', showing 2-foot contour intervals. The attached level/layer list itemizes the features which, to the extent they are visible on the photography, will be collected. Please review this list and notify us if the features we intend to show do not meet your needs. Digital map delivery will consist of AutoCAD version 12, 2D planimetric and contour files, and a Softdesk 3D-DTM file, on 3.5" floppy diskettes. Unless furnished with specific requirements, we will use our judgment in title and border information. As an option, we can provide you with high quality mylar laser plots, in 1/4 section area format. We estimate 9-10 sheet, ..:i:. 32" x 32" overall, will cover the entire area. Map Accuracy and Liability By accepting this proposal, you agree the work described herein will meet your intended purpose. The use of this map for a purpose other than that which is originally designed may render the map unreliable. Except where the ground may be obscured, map accuracy will comply with National Map Accuracy Standards. Briefly, these state that 90% of all well defined features shall be correct within 1/30 inch, and 90% of all elevations correct within 1/2-contour interval. If areas are obscured, contours will be dashed to indicate they are approximate. The accuracy standards should be applied only to the basic scale and contour interval 1" _ 100', 2' C.!. for which the maps were designed. MARKHURD's liability, in the production or use of these maps, for any inaccuracies that may be found in these maps, shall be limited to the correction of such inaccuracies, and shall not exceed the contract value of the maps. No representations or warranties are made other than those stated herein. Performance Schedule We will furnish MSA a set of aerial photographs indicating the control requirements within 3 days after receipt of notice to proceed. The time required to deliver the completed mapping will depend, to some extent, upon our work load when completed ground control is furnished. However, we estimate that delivery can be made within 12 working days after its receipt. e e /fIIARKHURD Cost Fee Schedule Our charge for the services described above will be as follows: 1. Topographic mapping, including blue area $6,800.00 2. Topographic mapping, less blue area $6,000.00 3. 1" = 100' mylar laser plots, 9-10 sheets $110.00 each When using control information provided by other than our own forces, an additional charge of $55.00 per hour will be made for excess office time, if any, due to erroneous control information. Payment Terms and Conditions Fees, as stated, shall remain in effect for 45 days from the date of proposal. If the date of acceptance occurs after this time period, we reserve the right to revise our fee and resubmit this proposal based on the present conditions. We will submit monthly invoices for the percentage of the work completed. Terms of payment will be net due 30 days from the date of invoice, and will be subject to a 1.5 % service charge on balance each month thereafter. We appreciate the opportunity of furnishing this proposal and look forward to being of service. If accepted, we would appreciate your either signing and returning the enclosed copy of this letter for our file, or issuing the appropriate purchase order for authorization. If you have any questions, please do not hesitate to contact me. Thank you. Very truly yours, MARKHURD ~~ Robert E.
