DESCRIPTION This Project consists of developing an 18-hole golf course and residential property on a 271.4 acre parcel of property in the city of Albertville, Minnesota (the "Project"). A portion of the golf course crosses the city corporate limits of Albertville and St. Michael (see map C). Cedar Creek Golf Course will be an 18-hole goJf course. The golf course will be an 18-hole, par 71, regulation length golf course. The golf course will play from 5,000 yards from the front tees to 6,200 yards from the back tees. The golf course will include a full-length practice range with ., 20-25 tee stations and a large practice putting green. The golf course has been designed to include wetlands areas, ponds, sand bunkers and mounding that will provide scenic, challenging and memorable golf holes. Multiple tees, large irrigated tees, greens and fairways will insure a playable golf course that appeals to all levels of golfers. The golf course will feature golf holes that have variety in length and challenge. It is anticipated that because of its close proximity to the high school (1.5 miles) an improved golf program at the high school would be possible. The clubhouse and parking lot will be centrally located on the golf course with access off County Road 118. The first and tenth tees, ninth and eighteenth greens, and the practice tee and practice green will all be in close proximity to the clubhouse/parking lot. The residential development of the project is proposed as a Planned Unit Development (PUD) and strives to achieve a lot size of 15,000 square feet in the single family lots, which is consistent with the zoning of the property. A total of 159 lots are over 15,000 square feet; 11 lots are less than 15,000 square feet; and the average lot size is approximately 16,700 square feet. The PUD consists of 170 single family lots and 74 townhome units for a combined total of 244 dwelling units. A total of 113 dwelling units are provided with golf course frontage and another 47 dwelling units are provided with frontage to proposed park land. The City of Albertville is included in the Joint Powers Water Board System, along with the cities of Hanover and St. Michael. Domestic water and fire protection service will be provided to the Project by the Joint Powers Water Board System. -:: In 1993, Albertville upgraded its municipal wastewater treatment facility, and the wastewater from the Project will be treated at the upgraded facility through an extension of Albertville's sanitary sewer collection system. A sanitary sewer main line installed through the Project will be designed to accommodate the wastewater flow from adjacent properties that are expected to be developed in the future and for which sanitary sewer service will be required. It is estimated that approximately 200 acres to the south of the Project will ultimately be serviced with sanitary sewer from the main lines within the Project. The timing, extent, and type of residential development of the land area to the south of the Project is not known. However, the utilities within the project will be designed so that subsequent extensions to the south can be accomplished. Construction activities for developing the Project include typical earthwork operations as necessary for grading of streets, installation of piping for extension of the municipal water and sanitary sewer systems, and minor earthwork operations for the development. MPCA approved erosion control methods, such as silt fencing, will be used to mitigate potential erosior.! onto adjacent properties or into drainage ways or wetlands. . The timing and duration of the construction is not established. The proposer desires to commence development of the area as expeditiously as possible. The rate of development of the Project is dependent upon timing of approvals as well as the rate at which housing is needed. 9. LAND USE The majority of the existing land use is agriculture, with portions of the property existing as wetlands. The estimated acreage of cover types before and after development are identified in the following section. Adjacent land uses include residential and agricultural. The City Approved Land Use Plan is attached as Map D. The proposed development is adjacent to a recently constructed residential development within the city of Albertville, Parkside Third Addition. The project is compatible with adjacent and nearby land uses which consists of recent residential expansions of the city of Albertville. Because adjacent land uses are consistent with the proposed Project, no environmentally negative impacts are anticipated. The majority of the 200, a'cres to the, south of the Project are also primarily agricultural with portions of the property existing as wetlands. Future residential development of the acreage to the south of the Project is compatible with adjacent and nearby land uses because it abuts the northerly boundary of the City of St. Michael which currently consists of agriculture and . residential developments. Also, the Albertville-St. Michael High School is located east of the future residential development south of the Project. Thus, existing land uses are compatible with the Project and surrounding areas. The rate of future development is unknown. There are no known past land uses that would contribute, to present environmental concerns in the Project. .,.( 11. FISH, WILDLIFE, AND ECOLOGICALL Y SENSITIVE RESOURCES Attached is the DNR review of ecologically sensitive resources provided for the Project EAW. No known occurrences of rare species or natural features were found within a one mile radius of the Project. Therefore, no conflicts are anticipated for this Project, as the total boundary of the project is within the one mile radius. There are no fish resources on or near the site that could be affected by the Project. The existing land area of the Project will be developed to include only those areas that are currently used for agricultural purposes. Wetland areas impacted by the Project will be mitigated on site. The project proposes "wetland replacement" such that a total of approximately 1.0 acres of wetland credits will be banked by the project proposer. This area will be used for mitigation in future projects, if any. ...' . . Minnesota Department of Natural Resources 500 Lafayette Road 51. Paul. Minnesota 55155-40_ May 27, 1997 Scott Dahlke Professional Engineer Meyer-Roblin, Inc. 1111 Hwy. 25 N. Buffalo, MN 55313 Re: Cedar Creek North Residential Development, T121N, R24W, Section '35, Wright County Dear Mr. Dahlke: The Minnesota Natural Heritage database has been reviewed to determine if any rare plant or animal species or other significant natural features are known to occur within an approximate one-mile radius of the above referenced project. Based on this review, there are no known occurrences of rare species or natural features in the area searched. The Natural Heritage database is maintained by the Natural Heritage Program and the Nongame Wildlife Program, units within the Section of Ecological Services, Department of Natural Resources. It is the most complete source of data on Minnesota's rare, endang~red, or otherwise significant plant and animal species, plant communities, and other natural features, and is used in fostering better understanding and protection of these rare features. The information in the database is drawn from many parts of Minne,sota, and is constantly being updated, but it is not based on a comprehensive survey of the state. Therefore, there are currently many significant natural features present in the state which are not represented by the database. We are in the process of addressing this via the Minnesota County Biological Survey (MCBS), a county-by-county inventory of rare natural features, which is now underway. Because survey work is in progress for Wright County, our information about natural communities judged to be significant by our program is quite good for that county. The MCBS survey work for rare and endangered animals and plants is less comprehensive; it is therefore possible that occurrences of these features exist in the project area for which we have no records. Because there has not been an on-site survey of the biological resources of the project area, it is possible that ecologically significant features exist for which we have no record.

PHYSICAL IMPACTS ON WA TER RESOURCES Physical or hydrologic alteration of surface waters outside the Project area will not occur. Development of the residential area within the Project will be consistent with the existing wetlands and wetland regulations. A combined total of 2,96 acres of the Type II wetland is proposed to be filled with material native to the Project. Minor relocation of portions of existing drainage ways within the Project area will be performed to conform with overall platting and stormwater and water quality controls. Wetland replacement is proposed on the Project site which is in accordance with current wetland mitigation laws. See attached Map E for the Wetland Mitigation Plan. Stormwater detentionlwater quality ponds will be constructed that will control storm water outflow rates and that will be designed in accordance with applicable stormwater quality criteria. -. The' location and size of these .facilities and the' overall, stormwater, control for the Project will be discussed in the Water Quality-Surface Water Runoff section to the Environmental Assessment Worksheet. ..." , , 13. WA TER USE a. A well is proposed to be installed as part of the golf course maintenance facilities. The well would function as a secondary irrigation water source only when surface water sources do not provide adequate resources for the goJf course irrigation system. The well is proposed to be a 4" cased well with sand screen point. A well permit has not been obtained; therefore, a unique well number is not known. The well is not proposed for domestic use. b. Appropriation of ground or surface waters is proposed to be used only as irrigation water for the maintenance of the golf course landscaping. An irrigation pond is proposed to be constructed that would receive surface water from water quality ponds associated with the Project as the main source of irrigation water. A well is proposed, as noted above, to function as a secondary source of irrigation water and would be used only when the supply of water in the irrigation pond is not maintail)ed by surface flows. A total of 9.5 acres of w~ter ponding is proposed as part of the project which will promote ground water recharge. Therefore, the appropriation of ground and surface water for irrigation purposes should not adversely affect groundwater conditions. Appropriation of ground or surface Waters is not anticipated during construction. The sole exception is if minimal dewatering of perched water is required for installation of the ~sanitary sewer collection system. The determination of whether any dewatering is even needed, or to the extent it may be needed, is dependent on whether water bearing seams: are encquntered during installation of the utilities. Dewatering during construction, if any, should not affect groundwater conditions, but will only affect perched water during the period of construction. c. The Project will receive water for domestic and fire protection purposes from the Joint Powers Water System for Albertville, St. Michael and Hanover. The DNR Water Appropriate is Permit Number for the supply 146359 and 455787. Estimated daily water consumption for the Project upon its completion is approximately 65,900 gallons per day using an av.erage of 2.7 persons per residential unit and a flow rate of 1 00 gallons per capita p~r day for water consumption. : 17. EROSION AND SEDIMENTATION Grading of streets, lots, and golf course within the Project will be performed. Grading outside of street rights-of-way will be performed as necessary, in order to develop lots and building pad elevations consistent with drainage design criteria. The developer's intent is to perform as little grading as possible for the Project and to perform only that grading which is necessary for home construction, golf course design, and drainage purposes. Erosion control by the use of silt fences will be used to preclude erosion into downstream water ways or wetland areas. The Project does not contain steep slopes that will require additional erosion control measures. All erosion control during construction will be performed in accordance with the City and MPCA's requirements that include the measures identified above. Detention/water quality ponds will be in place during and after construction that will serve as detention ponds for stormwater purposes as well as sedimentation basins for stormwater runoff prior to stormwater entering the existing wetlands and County Ditch No.9. The: sedimentation basins and stormwater runoff will be further discussed in the following section. _..f 18. WATER QUALITY - SURFACE WATER RUNOFF a & b. The quantity. of runoff from the developed Project will not increase the rate of discharge to downstream water courses nor will the quality of stormwater be adversely affected. This estimate is based on standard runoff parameters for the soil cover conditions that presently exist on the property, and the soil cover conditions and impervious areas that are expected to exist at the time the"Project is fully completed. The quality of stormwater runoff is expected to improve during and after construction due to the installation of detention/water quality ponds. The stormwater for a majority of the Project will ultimately discharge into County Ditch No. 9 (see Map "C") that is located on the east edge of the Project and flows to the south. Water from County Ditch No.9 eventually flows to the Crow River. Stormwater from the Project will enter detention/water quality ponds prior to being discharged at controlled rates to County Ditch No.9. The design of detention/water quality ponds proposes to reduce the rate of discharge to one-half the pre-development discharge rate. Typical designs reduce the discharge rate to equal the pre-development discharge rate. The Project design calls for larger ponds to be constructed to achieve the' one-half predevelopment discharge rate. Tllis is proposed as part of the project in an effort to aid in reducing drainage problems downstream associated with County Ditch No. 9. None of the storm water from the Project is discharged into lakes or protected streams of high water quality. The rate of stormwater discharge to County Ditch No. 9 will be controlled by the detention/water quality ponds that will store runoff during storm events and then release stormwater at contrqlled rates. Thus, the rate of flow of stormwater to County Ditch No. 9 will not be increased as a result of the Project. Stormwater from the Project enters the detention/water quality ponds through storm sewer piping and overland flow. The northerly portion of Cedar Creek (approximately 27 acres) adjacent to County Road 37 drains to the north ttlrough county and state highway ditches, as well as natural drainage ways to School Lake. The majority ,of this area of Cedar Creek is proposed as outlots and designated for multi-family residential development by the City Land Use Plan. Storm water discharge for this area will be aqdressed at the time of development of the outlots. The timing of this potential development and how it may be staged is not known. Regarding storm water quality, the Project will not degrade stormwater quality when compared to existing conditions. At the present time, a substantial percentage of the existing area is utilized for crops and agricultural purposes. As such, runoff from the existing agricultural property contains typical nutrients such as phosphorous and nitrogen that exist in fertilizers and agricultural waste. Runoff from the existing property also contains silt from erosion of crop land. Runoff from the completed Project may contain some nutrients from lawn fertilizers, such as those used on residential lawns and golf course landscaping, and contain some soil that may wash off streets into the storm sewer system. The detention/wC!ter quality ponds in the Project will, however, provide a mechanism for sedimentation of soils at:)d other foreign materials prior to the storm water flowing into County Ditch No.9. Thus, settleable solids should be reduced by construction of the Project. A majority of the stormwater from the Project will be routed through a number of ponds incorporated into the golf course design which will provide additional treatment and detention benefits. Therefore, the long term quality of stormwater runoff to County DitchNo. 9 is expected to be improved. 19. WA TER QUALITY - WASTEWA TERS a. The residential area of the Project will generate approximately 73,220 gallons of domestic wastewater per day based on an average of 3.2 persons per residential living unit and a flow rate of 100 gallons per capita per day. The wastewater generated by the Project will not include any industrial contributions. The developable land to the south is expected to generate similar residential flows once developed. b. & c. Albertville upgraded and expanded its wastewater treatment facility in 1993. All necessary hearings were conducted and permits and approvals obtained from the MPCA for the upgrade and expansion of the Albertville wastewater treatment system. The wastewater treatment facility, as it currently exists, consists of a pond system that provides secondary treatment prior to tertiary treatment to remove phosphorous before discharge to Mud Lake. The organic treatment capability of the facility can be expanded by incorporation of air, if needed, into the pond treatment system. The existing wastewater treatment facility is designed to treat 315,000 gallons per day with a CBOD loading pf 368 pounds per d~y. The wastewater treatment facility averages approximately '184,000 gallons per day (gpd), using available flow .. 'data, over a 12-month time period (April 1996 - April 1997). Higher than average flows occurred during May and June, averaging 200,000 gpd. Therefore, excess capacity of approximately 115;000 gpd currently exists throughout the year without any modification to the existing wastewater treatment facility. The attached sheet details a breakdown of flow quantities using existing flow quantities, approved residential plats, and proposed residential plats. Phasing of the proposed residential plats is considered in calculating potential flow quantities. An upgrade of the waste water treatment facility may be required to provide for residential development proposed for 1999 construction. The wastewater treatment facility is designed in such a manner that it can easily be modified to treat significantly higher flows and organic loadings. It is estimated that the wastewater treatment facility can be increased to treat an average daily flow of 1,373,000 gallons per day with a CBOD loading of 2,380 pounds per day, with modifications to meet higher standards. These designs are on file with the MPCA for the original treatment facility permit. Thus, Albertville's wastewater treatment facility has the capability to be easily modified for f~ture wastewater flows and loadings from areas outside the Project. 19.

Proposed plats are the Project (Cedar Creek) and Center Oaks. Phase-year denotes the phase number and proposed year for start of construction. Full absorption is typically 25 dwelling units per project per year. Both developments are proposed to be constructed in phases. The table below denotes a total of proposed units for each phase.

An upgrade of the Wastewater Treatment Facility may be required during the 1999 phase year. Conclusion is that Phase II and Phase III plats may have limitations imposed by the city in regard to number of occupancy permits allowed until actual flow data is verified to allow more connections or additional capacity measures are under construction at the Wastewater Treatment Facility. 20. GROUNDWA TER-POTENTlAL FOR CONTAMINA TION b. The potential for groundwater contamination is not a concern. The property to be developed does not contain any known special geologic/land form features that would be of a special concern regarding potential groundwater contamination. Further, the development is residential and will be totally serviced by Albertville's municipal wastewater collection system. c. Because the Project is residential, no toxic or hazardous materials will be generated from the Project. _..f 21. SOLID WASTE! HAZARDOUS WASTEI STORAGE TANKS a. Because the Project is a residential development, no hazardous wastes will be generated from the Project. Municipal waste will be generated from the Project and this waste will be collected and either disposed of or recycled in accordance with requirements the City of Albertville has for garbage pick-up and recycling. Construction of the Project will generate waste that is typical of residential home construction. Solid waste from these construction activities will be disposed of in accordance with applicable requirements. Licensed demolition landfill facilities are available in the area for disposal of construction materials. b. Petroleum products may be stored in the golf course maintenance facility for the servicing of maintenance equipment. It is anticipated that product storage will be above ground and accessible ~o golf course maintenance workers only. , During construction of the Project, it is expected that mobile fuel tanks will be on the property for the purpose of providing fuel for construction equipment. No permanent above- or below- ground tanks, other than noted above, are expected to exist after construction of the Project. .,.f 23. VEHICLE-RELA TED AIR EMISSIONS Based on the traffic data obtained from Question No. 22, and the fact tHat there is no reason to expect traffic congestion due to the Project, the Project will not cause any significant decrease in air quality due to vehicle-related air emissions. ...r 25. DUST/ ODORS/ NOISE During construction of the Project, dust may be generated as a result of grading, utility installation and street construction. The significance of any dust will be minimal and can be mitigated by the use of water trucks, if needed, during construction of the streets. Once the streets are paved, dust should not be a factor. The City requires that the streets be paved prior to occupancy; therefore, dust generation should not be an issue after street paving is complete. Further, park acreage and open areas are directly adjacent to the project and provide buffer areas during construction. Strong or potential odors will not exist during construction or after project completion. Noise generation will be typical of that for grading, utility installation, street construction, and home building. Major noise sources such as blasting will not occur. Especially sensitive receptors such as hospitals, etc., are not located in the vicinity of the Project. ..., 28. COMPATIBILITY WITH PLANS The residential portion of the Project is in conformance with the City Comprehensive Land Use Plan, dated June 17, 1996. The Jand use designated for this property is low density residential. There is no conflict between the proposed Project and the City Comprehensive Plan for the residential portion. The golf course will be considered a commercial operation and as such will require a Comprehensive Plan and Zoning Map amendment. ..,' 29. IMPACT ON INFRASTRUCTURE AND PUBLIC SERVICES As stated in prior sections, sanitary sewer and water utilities will be extended to serve the Project. The sanitary sewer servicing the Project will be designed to accommodate acreage in Albertville that is located south of the Project. County Road 11 8 is proposed to be upgraded by Wright County. The existing road is a two lane paved rural section road with granular shoulders. The road is proposed to be upgraded to County State Aid Highway requirements and would be a two lane paved rural section road with paved shoulders. The proposed upgrade will include: Regrading of the road, minor elevation and alignment adjustments, increase the structural section, and provide 8 foot paved shoulders on both sides of the road. Right turn lanes are proposed to be added where necessary as determined by the Wright County Higl}way Department. The road upgrade is included as part of the Wright County Highway Department5-Year Transportation Improvement Plan. Constru.c'tion is estimated to begin on the road upgrade in 1999. The road upgrade is not considered a "connected action" with respect to the Project. The road upgrade is proposed to proceed regardless of the Project development schedule or phasing. ..J 30. RELA TED DEVELOPMENT/ CUMULA T1VE IMPACTS a. It is anticipated that the area to the south of the Project that is located in Albertville (approximately 200 acres) will someday be developed for residential use. The timing of this potential development and how it may be staged is not known. The potential for development of this area is being considered at this time so that utility extensions into the Project can be designed to accommodate future development. b. This Project is not a subsequent phase of an earlier project. c. Development of adjacent land along the southeast border, Center Oaks, is proposed to be a single-family residential development. Center Oaks is proposed as a Planned Unit Development (PUD) and strives to achieve a lot size of 15,000 square feet for single family lots, which is consistent with the zoning of the property. A total of 1 08 lots are over 1 5,000 square feet; 5 lots are less than "15,000 square feet; and the average lot size is 16, 739 square feet. As it is adjacent to the Cedar Creek Golf Course, Center Oaks will have 17 dwelling units with golf course frontage. Another 12 dwelling units are provided with frontage to proposed park land within the Center Oaks development. An outlot of the Center Oaks project is proposed to be incorporated into the golf course design as area for the fairway and green of Hole 12. Center Oaks i~ proposed to be developed by others and an EA W has been prepared and sent out for review in August 1997. Development of bordering land to the northeast, Fairfield, is proposed to be a single-family residential development. Fairfield is proposed with a minimum lot size of 15,000 square feet, which is consistent with the zoning of the property. The development is proposed to have both single-family residential units and multiple-family residential units. Utilities to serve the development are proposed to be extended from existing developments to the east. Phase I of the development is being constructed in 1 997 (see map C). ..' Three outlots are proposed on the north portion of Cedar Creek. The city Land Use Plan has designated the area of the outlots to be used for multi-family residential development. Property adjacent to the north of Cedar Creek, along County Road 37, is designated for industrial development. Multi-family development of the outlots of Cedar Creek will provide a transition zone from the industrial area to single-family residential development. The timing of this potential development and how it may be staged is not known. d. Future development of other areas will be required to meet all city standards in place at the time of development. Because the remaining area to the south in Albertville is relatively small, cumulative environmental impact of this Project and all future development to the south, even if full residential development occurs, is negligible. The existing utilities have the capacity to accommodate future development, and a: major county highway runs adjacent to the property which may provide access. Future devel,opment in Albertville to the south of the Project will simply abut against the northerly city limits of St. Michael, which currently consists of residential development. .. t WRIGHT COUNTY MINNESOTA ~~ ~ 4-~'1' .S5--(6 >- ... ;Z ::> o u o u Z !! ;::: ...f ""'...-:r.:c2S......::=; ,R~ew, 11.21., CARVER II R.n.. , COUNTY i Me LEOD MIDLAND ATLAS COMPANY, INC.
