A City Council workshop was held on October 9, 1991 on the proposed business office park south of the existing industrial park and CSAH 21. Attendants to this workshop heard presentations from staff and financial consultant, Ed Tschida, on the options and strategies for development of business office park in this area. Discussion at this meeting centered on developing the first phase of the proposed business office park located in section 1 which is within the City limits. Staff did provide cost estimates for the installation of sanitary sewer, watermain, storm sewer and street improvements to the various alternatives described in the business office park report. Staff mentioned at the workshop that the business office park is planned to include area in section 12 which is currently in Spring Lake Township and the Orderly Annexation Area. The proposed first phase of the business office park has drainage from section 12 which flows through the development. The proposed business office park area in Section 1 and 12 is located between the Markley Lake and Cleary Lake drainage areas. The City has 2 foot contour maps for section 1 and only 10 foot USGS contour maps for Section 12. The land area in section 12 is generally flat in topography and the ten (10) foot contour map does not provide enough accuracy to adequately define the drainage areas for analyzing the drainage flows in this area. 4629 Dakota St. S.L Prior Lake, Minnesota 55372 Ph. (612) 447-4230 / Fax (612) 447-4245 A two(2) foot contour map would enable staff to better analyze the drainage needs for the proposed first phase and ultimate full development of the business office park. This map will also be useful in analyzing the drainage needs for the upcoming CSAH 21 road project and for the development of section 12 if this area is ever annexed into the City of Prior Lake. This map will be a planimetric (plan view) map as well which will depict the roads, buildings, fences, swamps, tree outlines, etc., to the extent that these features are visible on the aerial photography. Included in the quoted proposal is the cost to provide aerial photography and planimetric mapping for the Lakefront Park area. This map will provide the City a scale drawing (1 inch = 100 feet scale) showing the locations of the recently improved trails, sports facilities, swamps, tree outlines, fences and other features that are visible on the aerial photography. This map will assist the Parks department in plannin9 the future development of this park. An add1tional map at a smaller scale can be provided at a cost of $35.00 each. staff recommends that a 1 inch = 200 foot drawing also be acquired for planning and design purposes. The two proposals received from companies performing aerial photography and mapping work are summarized as follows: COMPANY SEC. 12 LAKE FRONT (640 AC.) (160 AC.) $3,970.00 $1,040.00 $4,225.00 $1,085.00 1.) HORIZONS, INC. 2.) MARTINEZ, CORP. DISCUSSION: The proposed aerial photography and planimetric/topographic map work will assist the Engineering department in estimating the drainage needs and associated costs for the proposed first phase of the business office park and for the proposed CSAH 21 project. Storm sewer and ponding costs have been estimated without the benefit of a two (2) foot contour map which can delineate the drainage areas more accurately. Aerial photography is flown in late fall or early spring in order to acquire the ground elevation data when the leaves are not on the trees. ALTERNATIVES: RECOMMENDATION: BUDGET IMPACT: ACTION REQUIRED: The pro~osed aerial photography and planimetr1c map for Lake front Park will provide the City with an accurate map ~howing the features of the park and assist 1n the future planning of this Park's development. The City has a two (2) foot contour map for the Lakefront Park area, however, this map was done before the improvements such as sports facilities, trails, hockey rinks, park buildings were completed in the park. The cost of producing maps for large areas such as the 640 acres and 160 acres for section 12 and Lakefront Park, respectively, can be done more cost effectively by aerial photography than by manually surveying the areas. The alternatives are as follows: 1. Approve a motion to authorize the aerial photography and mapping work for Section 12 and Lakefront Park as outlined in the attached proposal to Horizons, Inc. in the amount of $5,010.00. 2. Approve a motion to authorize photography and mapping work section 12 or Lakefront Park in the amount of $3,970.00 or respectively. the aerial for either separately $1,040.00, 3. Do not authorize the aerial photography and mapping work. 4. Table this item for a specific reason. The recommendation is to authorize Horizons, Inc. to perform the aerial photography and mappin9 work for section 12 and Lakefront Park to ass 1St in the future planning of these areas. This study was not budgeted. Financing of work would be from contingent reserve. current balance in cont1ngent reserve $63,225.00. the The is As part of the Consent Agenda, make a motion to authorize the aerial photography and mapping service work to be done by Horizons, Inc. for Section 12 and Lakefront Park areas and funding of this work to be from contingent reserve.
