AGENDA #: PREPARED BY: SUBJECT: DATE: INTRODUCTION: BACKGROUND: 8A BRUCE LONEY, ASSISTANT CITY ENGINEER CONSIDER RESOLUTION 94-58, APPROVING THE REVISED AND RESTATED JOINT POWERS AGREEMENT FOR SHAKOPEE BASIN WATERSHED MANAGEMENT COMMISSION OCTOBER 17, 1994 The purpose of this Agenda item is to consider approving a Revised and Restated Joint Powers Agreement (JPA) for the Shakopee Basin Watershed Management Organization (SBWMO). This revised JPA is necessary to meet the new State statutes which requires certain provisions be incorporated in Joint Powers Agreements throughout the State. A Joint Powers Agreement for establishing a Watershed Commission for the Shakopee Basin Watershed was approved by a City Council motion on June 24, 1985. From this Agreement a Watershed Management Organization was formed as required by the Metropolitan Water Management Act and Minnesota Statute 473.878. The SBWMO has met since 1986 to form a surface water management plan. This plan has been completed and has been approved by the Minnesota Board of Water and Soil Resources. The Metropolitan Surface Water Act applied to the seven county metro area which includes Scott County. In the initial Joint Powers Agreement, the membership of the Board consisted of one representative from each of the four local unit of governments within the SBWMO's boundary. These members and their appointed commissioners were responsible for the preparation and adoption of the initial watershed plan which was approved on April 24, 1991. Since the approval of the WMO plan, the State Legislature has passed a new Statute 103B which pertains to water planning and implementation. This statute allows the Board of Water and Soil Resources (BWSR) to adopt rules in regards to WMO plans. These rules called Chapter 8410 were adopted on May 27, 1992, and effective on August 1, 1992. The new rules require that the Joint Powers Agreement be modified particularly in regards to improvement projects. Previous JPA's in the state either required unanimous approval from all members in order to proceed with a capital improvement project or were silent in this matter as in the case of the SBWMO. The BWSR's new rules require a simple majority from the membership to authorize an improvement project and provide specific language relating to implementing improvement projects. 4629 Dakota St. S.E., Prior Lake, Minnesota 55372-1714 / Ph.

Attached to this report are the following documents for Council review: 1) Previous JPA adopted in 1985 2) Review letter from Glenn Kessel on initial draft JPA 3) Final draft of Revised and Restated JPA The City of Prior Lake has 1200 acres of area within the SBWMO which is the least amount of area among the four members. The 1200 acres is 9.4% of the total 12,785 acres within the WMO. The main changes in the Revised and Restated JPA can be summarized as follows: DISCUSSION: 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) Paragraph 6, Subdivision 1 - The BWSR shall be notified of appointments and vacancies to the SBWMO Board. Paragraph 6, Subdivision 3 - Updated to comply with BSWR rules. Paragraph 6, Subdivision 5 - Statement about Open Meeting Law. Paragraph 6, Subdivision 6, 7 & 8 - Additions to comply with BSWR rules in regards to alternative commissioners, decisions by Board and voting requirements and for allowing the Board to establish technical and citizen advisory committees. Paragraph 7, Subdivision 1 - This article was updated to comply with the new rules and to provide procedures on conducting business. Paragraph 7, Subdivision 2-20 - These articles were added, revised and modified to comply with the new rules. Paragraph 8, Construction of Improvements - This section was added as required by the rules to provide a mechanism in which WMO's can implement a construction improvement. This area in the original JPA did not state anything on construction of improvements, thus a separate paragraph revision was added. Paragraph 9, Finances - The major revision was to clearly state when a budget is adopted by the Board which is by an affirmative vote of a majority of all commissioners, then appointed. Also Subdivisions 5 and 6 have been added in regards to the financing of capital improvement projects and for appeals of members to the appropriation cost. Paragraph 10, Assessments - The Commission does not have the power to levy special assessments under the new rules. Paragraph 11, Duration - This section has been revised to comply with Minnesota Statutes 103B. Paragraph 13, Effective Date - Revised to reflect the current situation. A map is enclosed which shows the acreage of the City within the SBWMO and location which is the northwest area of the City. The final draft of the Revised and Restated JPA did incorporate the comments from the City Attorney, and he is satisfied with the Agreement with the exception that both the Mayor and City Manager should sign the Agreement. The main issue is that the new JPA will give more power to the WMO Board on improvement projects which can in effect approve a project that the City does not approve. There is a provision for appealing a Board's determination on the project or the apportionment of costs. The appeal would be referred to a Board of Arbitration consisting of three (3) persons. ISSUES: -2- T "T"""" ~"""_. " '. The arbitration process is in paragraph 9, subdivision 6 of the revised JPA. The previous JPA was silent on improvement projects and thus the WMO did not have the authority to implement a water project if necessary. The Board of Soil and Water Resources recognize this flaw and thus adopted rules for WMO's to revise their JPA's. The new rules provide the WMO's the authority to implement proje~ts if necessary. ALTERNATIVES: The alternatives are as follows: 1) Approve Resolution No. 94-58. 2) Disapprove Resolution No. 94-58 for specific reasons. 3) Table this item for specific reasons. RECOMMENDATION: Recommendation is to approve Resolution No. 94-58 so that the proper City officials can sign the Revised and Restated Joint Powers Agreement contingent upon Council directives. BUDGET IMPACT: This item has no impact on the budget. ACTION REQUIRED: A motion to approve Resolution 94-58 authorizing the Mayor and City Manager to sign the R vised and Restated Joint Powers Agreement for the Shakopee--BaSin ater Management Commission.

Prior Lake, MN 55372 Re: Joint Powers Agreement - Shakopee Basin WMO Dear Bruce: I have reviewed the draft of the Revised Joint Powers Agreement for the Shakopee Basin Water Management Commission as you requested. Please note that the first paragraph of the Agreement recites that the Agreement is made pursuant to the authority conferred upon the parties by Minn. Stat. s 471.59 and s 103B.201, et~. Minn. Stat. s 471.59 authorizes local government units to enter into joint powers agreements. 'Minn. Stat. s 103B.201 to .251 deals with metropolitan surface water management programs. Minn. Stat. s 103B.211, subd. l(a) (4) specifically provides that a joint powers agreement may provide that projects carried out to construct new drainage systems and improvements of existing drainage systems in a watershed may be carried out under the powers granted in Chapter 103D or 103E. Based upon such statutory authority, I recommend that the following changes be made to the Agreement. 1. I would recommend that the second sentence of paragraph 6, subd. 1 on page 3 of the proposed Agreement, be amended to read as follows: liThe Board of Water and Soil Resources shall be notified of all appointments to the Board and of all vacancies within thirty (30) days of the appointment or vacancy." Minn. Stat. s 103B.227 requires that notification be made within 30 days. '-.. . .....,_._.__........._. 4._.__...______...._... ...---_. Lommen, Nelson, Cole &: Stageberg, P.A.

I would recommend that paragraph 6, subd. 3 on page 3 of the proposed Agreement be amended to read as follows: "A commissioner may not be removed from the Board prior to the expiration of his or her term, except for just cause, by the governing body who made the appointment in accordance with the rules prescribing standards and procedures for removing members of watershed management organization boards for just cause as promulgated by the Board of Water and Soil Resources." 3. I would recommend that paragraph 6, subd. 7 on page 4 be amended to read as follows: "Decisions by the Board shall require an affirmative vote of a majority of all commissioners, then appointed, except that a decision on a capital improvement project shall require a two-thirds (2/3) affirmative vote of all commissioners, then appointed." 4. I would recommend that paragraph 7, subd. l(d) on page 5 be amended to read as follows: "The Commission shall publish and distribute a newsletter or other appropriate written communication at least annually to watershed residents. The newsletter or other communication shall explain the watershed's programs and list the officers and telephone numbers." 5. I would recommend that paragraph 7, subd. 3 on pages 5 and 6 be deleted or modified. I do not find specific authority which authorizes the Commission to order any governmental unit to carry out its local water management program in the statutory framework set forth in paragraph 1 of this letter. In addition, I concur with Karen Marty's comments in paragraph 1 of her letter regarding the advisability of such a provision. 6. I would recommend that paragraph 7, subd. 4 on page 6 be amended to read as follows: t . -...- .....----,.,.--...~._....._....-._.._-........~ - ."-. --- -' . - . ~ . . .. -' .... .' ~ .. . . -.' .

"The Commission may acquire, operate, construct and maintain only the capital improvements, if any, delineated in the watershed management plan adopted by the Board which the plan states will be constructed by the Board, following the procedures set forth in Minn. Stat. s 103B.251 and/or Chapter 103D or 103E." 7. I question the authority granted the Commission in paragraph 7, subd. 7 on page 6. I did not find any specific statutory authority allowing the Commission to enter upon lands within or without the watershed to make surveys and investigations in Chapter 103B. However, Chapter 103D does authorize watershed districts to exercise the powers of eminent domain. When those powers are exercised, there is authority to enter upon lands for investigations and surveys. 8. I would recommend that paragraph 7, subd. 10 on page 6 be modified to read as follows: "The Commission may collect money, subject to the provisions of this Agreement, from its members and from any other source, if approved by the affirmative vote of a majority of all commissioners, then appointed. " 9. I would recommend that paragraph 7, subd. 18 on page 8 be amended to read as follows: "The Board shall at least every two (2) years solicit proposals for all legal, engineering, auditing, and other technical or professional services before retaining the services of a professional or extending annual service agreements." 10. Paragraph 8, subd. 1 on pages 8 and 9 should be amended to comply with ~nn. Stat.

I would recommend that paragraph 9, subd. 3 on pages 10 and 11 clearly spell out the vote required to adopt the administrative budget in terms of the affirmative vote requirement, such as a majority of all the Board of Commissioners, then appointed. 12. I concur with the comments of Karen Marty, City Attorney for the City of Shakopee, in her Memorandum dated August 9, 1993, comments 1, 2, 3, 4, 6 and 7. With respect to Karen's termination comment (comment no. 5), early termination by a city is governed by Minn. Stat. Chapters 103B or 103D. Minn. Stat. ~ 103B.221 outlines the procedure for termination of a watershed district. Minn. Stat. ~~ 103D.255 and 103D.271 establish procedures for withdrawal of territories and for termination of watershed districts. I would recommend that those provisions be incorporated by reference in the proposed Agreement. If all parties agree that they have the authority to provide some easier means of termination even though the Statute does not seem to authorize it, I would recommend some modifications to the termination provisions. Bruce, please give me a call should you have any questions regarding these comments/recommendations. For your reference, I have enclosed a copy of relevant portions of Minn. Stat.

Subdivision 3. On or before July I of each year, the Board shall adopt a general administrative budget for the ensuing year and decide upon the total amount necessary for the general fund. Adoption of the general administrative budget shall require an affirmative vote of a majority of all commissioners, then appointed. The secretary of the Board shall certify the budget on or before July I to the Clerk of each member governmental unit, together with a statement of the proportion of the budget to be provided by each member. The Board shall, upon notice from any member received prior to August 1, consider objections to the budget. After considering the objections, the Board may amend the budget. The budget may not be adopted if the governing bodies of three (3) or more member units object to it. Subdivision 4. An improvement fund shall be established for each improvement project ordered by the Commission. Each member shall pay its proportionate share of the cost of the 17599 r09/02/94 9 . improvement in accordance with the determination of the Board as set forth herein. The Board, in its discretion, may require members to make advance payments based upon estimated costs, subject to adjustment to reflect actual costs, or may bill the members as costs are actually incurred. Members agree to pay billings within thirty (30) days of receipt. The Board or the member awarding the contract shall advise other contributing members of the tentative time schedule of the work and the estimated times when the contributions shall be necessary. Subdivision 5. All costs of capital improvements designated in the Board's adopted watershed management plan for construction by the Board shall be apportioned on one of the following bases: (a) The ratio of real property valuation of each member within the boundaries of the benefited area to the total real property valuation within the entire benefited area; (b) The ratio of storm water runoff produced by each member within the boundaries of the benefited area to the total runoff of storm water produced by the entire benefited area; (c) A combination of the above apportionment methods; (d) Pursuant to Minn.

MEMORANDUM David Hutton, Director of Public Works/City Engineer BKL SUBJECT: Preliminary scope of services Modifications to the Savage Fen groundwater model. General The purpose of the project proposed in this document is to defme those areas, beyond the Savage city limits, where the construction and operation of high capacity wells will have an adverse impact on Eagle Creek, Boiling Springs 1 and 2, or the Savage Fen Wetland Complex. In addition to this, the project will also entail a review of the feasibility of using the Kraemer and/or Shiely quarries as potential sources of potable water for communities in the area. To accomplish these objectives, Barr proposes to generate at least two modified groundwater models from the existing Savage Fen Model. One will address Bloomington, Burnsville and the Kraemer quarry, while the other will focus on the Shiely quarry and Prior Lake area. In addition, Barr will meet with the Minnesota Department of Health (MDH) and perform preliminary studies to determine treatment criteria for the potential water sources at Kraemer and Shiely quarries. Finally, the work on the Shiely quarry will include a detailed review of the proposed increase in dewatering to determine if it will adversely impact the City of Shakopee's wells, Deans Lake or any of the surrounding wetlands. The following is a preliminary outline of tasks required to accomplish the project objectives for each community involved. City of Burnsville Wells Assessment Barr proposes to modify the existing regional Savage Fen groundwater model and specifically tailor it to the Bumsville Kraemer Quarry area. Following are the tasks needed to perform the modifications to the Savage model in order to evaluate the potential impacts from the City of Burnsville future wells. Task 1. Task 2. Task 3. Review existing information . . . City of Bumsville Wells Comprehensive Water Study Kraemer Quarry Pumping Rates Modify Model . A sweep of all nodes to ensure that they coincide in all layers and in neighboring analytic elements Refinement of elements near the Kraemer Quarry Refinement of leaky elements near City of Burnsville wells . . Modeling Scenarios . . . . Present situation Proposed location of wells Three or four additional location alternatives Use of Kraemer quarry water in lieu of some or all wells t . Evaluation of Kraemer Ouarry In addition to the model modifications, Barr proposes the following tasks to review the use of Kraemer Quarry dewatering water as a source of potable water. Task 1. Task 2. Task 3. Gather data . . . Verify quarry life and ultimate dewatering needs Review existing water quality data Review existing dewatering draw down data Treatment requirements . . . Meet with MDH to determine criteria for treatment requirements Scope tasks required to gather additional data, based on MDH meeting Produce preliminary design recommendations report Dewatering effects . . . Obtain wetland delineation data Review groundwater model results and determine effects to delineated wetlands Produce report summarizing findings Savage/Shiely Quarry Assessment Barr proposes to make further modifications to the Savage Fen model near the Shiely Quarry to eliminate minor model instabilities and to improve accuracy in the Shiely pit area. To provide a more accurate assessment of the potential impacts of an increase in dewatering rates on the Savage Fen Wetland Complex, Eagle Creek, Boiling Springs 1 and 2, the City of Shakopee's wells and Dean's Lake, we would need to perform the following tasks: Task 1. Task 2. Task 3. Review existing information . . . . City of Shakopee wells and plans for future expansion Review geologic information in that area Shiely quarry pumping history, including draw down and water quality information Existing studies on Deans Lake Treatment requirements . . . Meet with MDH to determine criteria for treatment requirements Scope tasks required to gather additional data based on MDH meeting Produce preliminary design recommendations report Dewatering effects (Meyer model) . . . . Obtain wetland delineation data and review past Dean's Lake work Produce Meyer model water balance for the Dean's Lake and Shiely Quarry area Produce report summarizing findings Meet and coordinate with Minnesota Department of Natural Resources to avoid duplicate work on the area .. . ,_,_~,-,,,~,"~,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,_~____"~,,.,~,,,,,,,,,,,_,,,,_,,,.<<_,,__'~M__"__""'_"_"'__'___~_~__'~_""'_"~~">~'""_~"" . , . ',- Task 4. Task 5. Modify Model . Eliminate instability by revisiting the grid to relocate nodes that do not coincide. A sweep of all nodes will be needed to ensure that they coincide in all layers and in neighboring analytic elements Refine elements near the Shiely quarry Refine leaky elements beneath Dean's Lake Refine elements near the City of Shakopee wells Incorporate warranted geologic detail in the area. . . . . Modeling Scenarios . . . Present situation Impact of an increase of pumping rate at the Shiely quarry Three or four modeling scenarios to evaluate the effect of different pumping rates and identify specific well locations needed to dewater the quarry Produce report summarizing findings . City of Prior Lake Assessment The tasks in this assessment are identical to those performed for Bumsville with the following differences: . The details of the geologic information near the Burnsville wells were already compiled and analyzed in a prior modeling study. More work will be required to render a realistic simulation of the groundwater flow field in the Prior Lake area. . The details for the quarry will have already been performed while evaluating the impacts of the Shiely quarry. . Review City Comprehensive Water Study. . Model runs may include moving all of the city's wells to the west side of the city to verify if that would impact the natural resources already listed. . Prior Lake work would exclude the separate tasks involving the quarry. City of Bloomington Well Assessment Barr proposes to address the City of Bloomington's future wells in a two phased approach because there is a high likelihood that they will not adversely affect any of the natural resources discussed earlier. The first phase would be a screening step to verify whether or not additional work is warranted. If additional work is deemed necessary then a second more extensive modeling effort would begin. To accomplish these goals the following tasks would be required: Screening Step. Task 1. Review existing information . . . City of Bloomington's existing wells Comprehensive Water Study Proposed ultimate groundwater needs T . Task 2. Task 3. Modify Model . . Include effects of the proposed City wells at Minnesota river boundary of model Minor refinement of elements near the Minnesota River Evaluate potential effect . . . Present situation Proposed wells Letter report Task 1. Evaluation Step. Task 2. Task 3. Review of existing data . . . Review of Bloomington geology and wells records Determine new model boundary conditions Gather calibration data relevant to Bloomington Modify Model . . . Modify model layers to include geology north of the Minnesota River Modify leaky elements near the Minnesota River Add Nine Mile creek linear elements Modeling Scenarios . . . . Present situation Proposed location of wells Three or four additional location alternatives Produce report summarizing findings Project Cost and Schedule Barr proposes to complete the work listed in this document according to the attached Alternative Water Supply Evaluation Schedule. Barr further proposes to complete the work as listed in this document for the costs shown on the attached Alternative Water Supply Evaluation Cost Estimate with the understanding that task modifications may alter final proposed costs.

I . . . ) SAVAGE FEN MANAGEMENT PLAN CITY OF SAVAGE EXECUTIVE SUMMARY The Savage Fen Wetland Complex contains calcareous fens, A calcareous fen is defined by Minn Rule Pt. 8420.1020 as "a peat-accumulating wetland dominated by distinct groundwater inflows having specific chemical characteristics. The water is characterized as circumneutral to alkaline, with high concentrations of calcium and low dissolved oxygen content. The chemistry provides an environment for specific and often rare hydrophytic plants." The disproportionately high number of rare plant species provides the driving force for state protection of calcareous fens. The Minnesota Department of Natural Resources (lVIDNR), under authority ofMinn Rule Pt, 8420.1010, requires the preparation of Fen Management Plans to ensure the long-term protection and management of calcareous fens, This rule states that a calcareous fen may not be filled, drained, or otherwise degraded except as provided for in a management plan approved by the commissioner of the lVIDNR. The Savage Fen Management Plan was prepared by the City of Savage in conjunction with an Alternative Urban Areawide Review (AUAR) of the Metropolitan Urban Service Area (MUSA), as required by the MDNR and the Minnesota Pollution Control Agency (MPCA) as part of the environmental review process for the trunk sanitary sewer improvements proposed by the City in 1993. The Savage Fen Management Plan and the AUAR will assist the City and regulatory agencies in the environmental review and permitting of future development projects and facilitate the City's comprehensive planning process for the MUSA expansion area. The Savage Fen Wetland Complex encompasses an area of approximately 425 acres. Approximately 64 acres have been classified as calcareous fen. The remainder of the wetland complex consists of WetJSedge Meadow, Shrub-Carr, Low Prairie, and Lowland Hardwood Forest plant communities. Maps of the various plant communities are included in the Savage Fen Management Plan. The Savage Fen is the largest of 76 known calcareous fens within Minnesota. Five state-listed threatened plant species have been found in the Savage Fen Wetland Complex: Carex sterillis (Sterile Sedge); Eleocharis rostellata (Beaked Spike-rush); Rhynchospora capillacea (Fen Beaked-rush); Seleria uerticillata (Nut-rush) and Valeriana edulis uar_ ciliata (Valerian). Three special concern (i,e. rare) plant species have been found in the Savage Fen Wetland Complex: Cladium mariscoides (Twig-rush); Cypripedium candidum (White Ladyslipper); and Tofieldia glutinosa (False asphodel), All of these species prefer habitats in which calcareous and mineral-rich soils and water prevail. Some are known only to occur in a calcareous fen habitat. The soils and stratigraphy within the Savage Fen Wetland Complex typically consists of a thin layer of residuum and rubble on top of the Prairie du Chien Group bedrock (dolomite). Above the residuum are silt and sand deposits that are the result of sediment being washed down from the bluff P:\SS\2370060\2617_1\~ 1 . and deposition of the ancestral Minnesota River. These deposits grade upward to river deposits of sand and silt and lake deposits of clay and silt layers that contain variable amounts of organic and shell material. The clays and silts are commonly calcareous (marls), Overlying the marls, clay and silt are brown to black fibric peat that contains gastropod and ostracod shells, Within the peat there are variable percentages of sand and silt, either from the bluff or river flooding. The surficial soil is black saprolitic peat that is rich in organic material. These organic-rich soils are described as histosols and histic epipedons in the mandatory technical criteria established by MDNR and are an intrinsic characteristic of fens. The peat and related deposits appear to be continuous east to west across the Savage Fen Wetland Complex and contain layers of mixed mineral soil and peat. The peat related to the fen may grade into peat related to lake deposits on the north side of the wetland complex. The peat and related soils appear to be thickest (20 to 35 feet thick) in the calcareous fen areas. Reducing conditions in the soil/water are prevalent in the peat zones associated with the calcareous fen portions of the wetland complex, Oxidizing conditions are typical of the non-calcareous fen portions of the wetland complex, Carbonate precipitation peaks at a depth of 5 to 7 cm below ground surface and there is a correlation in concentrations of manganese, strontium, calcium, and carbonate. Iron sulfide precipitates in the shallow groundwater of the peat. Many factors contribute to the health of calcareous fens, The Savage Fen Management Plan addresses these factors, which include: minimization of stormwater runoff into the wetland complex; control of sedimentation from construction activities in the vicinity of the wetland complex; and prescribed bums to reduce competition between the rare calciphyilic plants and shrubs. However, the single most important factor in protecting the health of the fen appears to be maintaining the upwelling groundwater conditions which bring calcium and low dissolved oxygen waters to the root zone of the plants and assists in the formation of peat. A comprehensive regional groundwater flow model was developed for the Savage Fen Management Plan. The model was used to evaluate changes in groundwater flow conditions at the Savage Fen Wetland Complex resulting from installation of new municipal wells and increases in impervious area, which might affect recharge to the aquifers. Three aquifer units were modeled: the glacial drift aquifer; the Prairie du Chien Group (dolomite); and the Jordan Sandstone, It is widely believed that the calcium-rich waters which upwell into the Savage Fen Wetland Complex are derived from the Prairie du Chien Group and the glacial drift. The Multi-Layer Analytic Element Model CMLAEM) was used to model groundwater flow in the three units over a large area that includes most of Scott and Dakota Counties. Higher levels of detail were included in the model in the Savage/Prior Lake areas and especially in the immediate vicinity of the Fen. The model includes special elements which simulate the effects of recharge by precipitation, leakage from lakes and rivers, spatial changes in the hydraulic properties of the aquifers, truncation of the aquifers by geologic features, evapotranspiration, leakage between aquifers, and pumping wells. The model used, as input data, information from geologic atlases, regional geologic studies, well test data, surface water flow measurements, and results from prior P:\SS\2370060\2617_1\JnMGI 2 T . - - - I I I I I I II I 'I:. - , . .I ""'f i I - ,,"" 4 _I .=:~4! .. - r- I. . modeling studies. The model was calibrated, on a regional scale, to steady-state hydraulic head measurements that were summarized as piezometric contour maps in the Scott and Dakota County Geologic Atlases. Near the Savage Fen Wetland Complex, the model was calibrated to actual water level measurements from wells. Base flow measurements in Eagle Creek were derived from several temporary gaging stations set up along Eagle Creek and these data were also used to calibrate the flow model. The calibrated MLAEM groundwater flow model was used to evaluate future water-supply well locations for the City of Savage to meet projected water demand. Hypothetical well locations were selected throughout Savage for this evaluation. Simulations were performed with the hypothetical wells pumping and the model was used to predict the change in hydraulic head at the fen wetland complex resulting from these hypothetical wells. A large simulated reduction in hydraulic head within the Savage Fen Wetland Complex was considered an indication that the hypothetical well could reduce the upwelling conditions at the fen wetland complex and thereby adversely affect the fen. The modeling results indicated that no more than one additional well in the Jordan Sandstone (pumping at a maximum rate of 800 gallons per minute), located in the southernmost portion of the City, could be operated without adversely affecting the fen. A larger well or more wells located in other parts of Savage pumping from the glacial drift, the Prairie du Chien Group (of which the Shakopee Formation is part oD, or the Jordan Sandstone are predicted to cause adverse effects on the Savage Fen Wetland Complex. The major conclusion drawn from the modeling study is that the City of Savage should not place additional wells in the glacial drift, the Prairie du Chien Group, or the Jordan Sandstone. The City may place additional wells in deeper aquifers, specifically the Franconia-Ironton-Galesville aquifer or the Mt. Simon-Hinckley aquifer, These two aquifers are separated from the Prairie du Chien-Jordan Aquifer by the St. Lawrence Formation confining unit (for the Franconia-Ironton-Galesville aquifer) and by the Eau Clair Formation (for the Mt. Simon- Hinckley Formation). Although not specifically studied in this Fen Management Plan, it is likely that additional high-capacity wells located in areas adjacent to the City of Savage (within the three aquifer units discussed above) will also result in adverse effects to upwelling conditions at the Savage Fen Wetland Complex. This conclusion is based on the modeling results of hypothetical wells located at the southern city limits of Savage. These hypothetical wells resulted in unacceptably high drawdowns in the Savage Fen Wetland Complex. It is reasonable to conclude that additional wells located south of Savage will also cause adverse draw down effects at the Savage Fen Wetland Complex. The City of Savage could obtain additional water from deeper aquifers or from another source, such as nearby quarries (e.g, the Kramer Quarry and the Shiely Quarry), Dewatering activities at these quarries is ongoing and the water pumped during the dewatering process could be utilized for water supply purposes, The modeling results indicate that increased dewatering withdrawals from the Kramer Quarry could have adverse impacts on the upwelling conditions of the Savage Fen Wetland Complex. The modeling results indicate that the increased withdrawals at the Shiely Quarry will not adversely affect upwelling conditions at the Savage Fen Wetland Complex. The P:\SS\2370060\2617_1\l1MDl 3 T . ) I Shiely Quarry currently pumps approximately two billions gallons of water per year. A modeling scenario was performed whereby the Quarry dewatering was increased to four billion gallons per year, with negligible effects on the hydraulic head in the vicinity of the Savage Fen Wetland Complex. There appears to be three reasons for the lack of hydraulic effects caused by increased pumping at the Shiely Quarry: (1) the Quarry is adjacent to the Minnesota River and leakage from the river undoubtedly takes place; (2) the Shiely Quarry is approximately 2 miles west of the Savage Fen Wetland Complex and lateral to or slightly downgradient of the Savage Fen Wetland Complex and (3) there is a buried bedrock valley between the Shiely Quarry and the Savage Fen Wetland Complex which appears to hinder hydraulic communication between the two areas. This bedrock valley feature was included in the model. I I I I The MLAEM groundwater model was also used to examme the effects of increasing the impervious area in the City of Savage due to the MUSA expansion, Increases in impervious area, due to urbanization, may reduce the recharge rate of the aquifers from direct precipitation. The contribution of recharge from direct precipitation and leakage from landlocked basins in Savage for current conditions was calculated from water-balance analyses and these values were incorporated into the model during the calibration process. Urbanization conditions were estimated from the City's 1991, 2001, 2010, and ultimate land use plans. The urbanization conditions were translated into reductions in recharge due to increased impervious area. The modeling results indicate that a reduction in hydraulic head of approximately 3 inches would take place at the Savage Fen Wetland Complex under full development. This reduction is deemed to be acceptable to maintaining the health of the fen. - I I I The recharge in the model over the City of Savage was reduced to zero (including all basins and lakes) in order to evaluate an extreme (and highly unlikely) situation and to evaluat~ the sensitivity of the model to changes in recharge. The resulting change in the hydraulic head at the Savage Fen Wetland Complex was approximately 1 foot. These results indicate the hydraulic heads (and upwelling conditions) at the Savage Fen Wetland Complex are relatively insensitive to reductions in the infiltration rate in Savage. This is especially true in comparison to the effects caused by the inclusion of new municipal wells. The insensitivity to variations in infiltration within Savage indicates that the hydraulic head conditions in the Savage Fen Wetland Complex are the result of regional flow conditions rather than local flow cells. {I I I I The regional modeling studies focused on the effects of the Savage Fen Wetland Complex but also examined potential adverse impacts to Eagle Creek and Boiling Springs, in particular, Surface water monitoring of Eagle Creek, performed as part of this Fen Management Plan, suggests that water in Boiling Springs (and other small springs along Eagle Creek) originates in the Prairie du Chien Group and reaches the ground surface because the hydraulic head in the Prairie du Chien Group is higher than the land surface. This is exactly the same condition that exists at the Savage Fen Wetland Complex. The modeling studies lead to the conclusion that protection of the Savage Fen Wetland Complex's upwelling conditions will also protect the flows in Boiling Springs and the other small springs of similar character. I I I I P:\SS\2370060\2617_1\JnMaI 4 I I . - - a: i . The conclusions drawn from the regional groundwater modeling are as follows: (1) the City of Savage should not install additional wells within its City limits in the glacial drift, the Prairie du Chien Group or the Jordan Sandstone; (2) The City of Savage should explore alternative water sources such as deeper aquifers or obtaining water from one of the quarries; (3) if a quarry is chosen as a future water supply source, the Shiely Quarry appears to be the best choice; (4) it appears that additional high-capacity wells in areas immediately adjacent to Savage might adversely affect upwelling conditions at the fen; (5) upwelling conditions at the Savage Fen Wetland Complex will not be adversely affected by future development in Savage and hydraulic head conditions at the wetland complex are relatively insensitive to variations in local recharge; and (6) regional flow conditions responsible (in part) for the health of the Savage Fen Wetland Complex are also responsible for Boiling Springs (along Eagle Creek) - protection of upwelling conditions at the wetland complex should also protect the spring, . I I II i The Savage Fen Management Plan addresses the need for continual monitoring of the health of the wetland complex. General monitoring guidelines and procedures are outlined in the Plan, along with steps for further action should monitoring results indicate a potentially adverse condition. Best Management Practices are briefly addressed. Also included in the plan are general guidelines for protection of groundwater quality and Wellhead Protection Area delineation for existing municipal wells in the City of Savage. . -- QJ " Ij f!
