The developer should be aware that if they intend to release storm water to County Ditch 9 and or cross the Ditch as shown in the plan they will have to approach the Wright County Board for approval. They can contact the County Auditor, Doug Gruber to obtain the procedure they need to follow. We have dealt with some of these in the past and it has taken some time so they may want to approach the Board early in the process. As noted in the document a Wetland Conservation Act (WCA) permit will be required for the proposed wetland fills. We have not done a thorough investigation of the plan as yet and will wait for this WCA process to address all our concerns when we can asses the reasoning of the developer. One comment for now, relates to phase three and the fact the lots 6-11 seem to be pinched between the wetland and the road. We are generally not in favor of this type of arrangement because it leaves little buildable room and invites violation during the construction process and as lot owners attempt to fill for yards. By moving the road slightly to the north larger buildable areas could be left for these lots. We look forward to working with the city as we have in the past to resolve the wetland and ditch issues and to garner the best possible development plan for this parcel. Sincerely, ~.

Paul, Minnesota 55155-4010 August 24, 1999 Pete Carlson, City Engineer City of Albertville 5975 Main Avenue NE Albertville, MN 55301 RE: KC Land Company Development (Albert Villa) - Single Family Residential Development Environmental Assessment Worksheet (EA W) City of Albertville, Wright County Dear Mr. Carlson: The Minnesota Department of Natural Resources (DNR) has reviewed the EA W for KC Land Company Development (Albert Villa), which consists of 347 single family lots on 235.17 acres. We offer the following comments for your consideration. Figures showing the locations of wetlands do not appear to be consistent. For example, the figure showing the layout for Phase 1 depicts a wetland area in Lots 1-3 as extending into the Phase 2 area. However, the figure for Phase 2 does not show this wetland area which should appear in Lots 17-19. There is also a drainage way depicted in the figure for Phase 1, but not in the figure for Phase 2. The assessment of wetland impacts appears to be based solely on the road development and does not factor in wetland fills necessary to develop some of the lots. In Phase 1, some wetland fill may be necessary to develop lots numbered 1,2,3,6, and 12. In Phase 2, lots numbered 10, 33, 34, 35, 53, and 54 appear to require wetland fill. In Phase 3, lots 1 and 6 - 11 appear to require wetland fill. We recommend that the City of Albertville require an estimate of the total wetland impacts likely to result from residential lot development. This impact should be mitigated before construction by the developer by creating an on-site wetland mitigation bank for use by lot owners. The lots owners would have to go through the mitigation sequencing process before being allowed to withdraw credits from the mitigation bank and the developer would have to be responsible for assuring the successful creation of the replacement wetland. Section 12 - Physical Impacts on Water Resources The EA W indicates no impacts to Swamp Lake (Protected Water 86-14 P), yet there is a storm water pond proposed in close proximity. The Ordinary High Water (OHW) level for this lake is 952.50. Any work done below this elevation will require a DNR Waters Permit.

PROPOSED PROJECT DESCRIPTION ABSTRACT Description: KC Land Company proposes to develop a 235.17 acre parcel from agricultural land to 347 single family lots with a minimum size of 12,500 square feet, in three phases over a five year period. All of the phases will be constructed within the City of Albertville, Minnesota. RGD: City of Albertville Contact: Pete Carlson, City Engineer, 5975 Main Avenue NE, Albertville, MN 55301,612-497-3384. The Project consists of developing a 235.17 acre parcel from agricultural fields, wooded areas, wetlands and two farmsteads to residential property on in the City of Albertville, Minnesota (Project). The planned development consists of three phases. Phase I will commence grading and preliminary construction as soon as possible and is scheduled to be completed in 2000. Phase II is scheduled to begin construction in 2000 to be completed in 2002, and Phase III is planned to be completed in 2004. Phase I proposes developing 43 single family lots on approximately 43 acres in the northwest portion of the proposed project area. Phase II proposes developing 146 single family lots on approximately 92 acres in the central portion of the proposed project area. Phase III will be composed of 158 single family lots on approximately 100 acres in the portion south of County Ditch No.9 on the proposed project area. Included in this property are areas of roads, parks, ditches, wetlands and utility easements. 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 Board Water System. The wastewater lines from the Project will be connected to existing main lines located to the north and east that were installed in the Oaks Center development. The sewer lines were designed to accommodate this expected Project and further development of the property adjacent the Project. The wastewater will ultimately be routed to the Albertville wastewater treatment facility that was upgraded in 1993 I I I I I I I I I I I I I I I I I I I and is undergoing further expansion. The completed expansion of the wastewater facility that is planned to be functional in 2001. Sanitary sewer main lines installed through the Project will be designed to service further development from the adjacent undeveloped properties to the west. It is not known what type, timing, or extent of development will occur on properties adjacent the Project. Activities during Project construction will include typical earthwork associated with grading for streets, and stormwater ponds, and installation of utilities including municipal water, sanitary sewer, and storm sewer lines. MPCA approved erosion control methods such as silt fencing will be used to mitigate potential erosion onto adjacent properties or into drainage ways and ditches. The timing and duration of construction are not established, but the proposer wishes to commence grading and preliminary construction as soon as possible. The initiation of construction is contingent upon the receipt of approvals and the rate of development is dependent on the need for housing. Section 9. LAND USE Current land use of the Project site is primarily agricultural, with portions of the property existing as wetlands and wooded areas. In addition, two farmsteads are located on the property. The estimated acreage of cover types before and after development are identified in the following section. Adjacent land uses include residential, agricultural, and recreational. The City of Albertville Comprehensive Plan Development Framework is included as Figure D. The proposed development is bordered on the south by residential development in the City of St. Michael, on the west by agricultural land, on the north by CSAH 18 (beyond which is the golf course and residential development) and on the east by Swamp Lake. Because adjacent land uses are consistent with the Project no environmentally negative impacts are anticipated. The impact of the Project and any potential conflicts with Swamp Lake and other wetlands on the Site will be addressed in sections 11 and 12. Due to the historical agricultural use of the Project site no environmental hazard due to past land uses is likely. I I I I I I I I I I I I I I I I I I I Section 10.

FISH, WILDLIFE, AND ECOLOGICALLY SENSITIVE RESOURCES Wildlife resources at the Project site and in adjacent areas include Swamp Lake, County Ditch No.9 and associated drainage ditches, several wetlands, and woodland areas. a) The most significant wildlife resource adjacent to the Project site is Swamp Lake, DNR protected wetland #14P, on the eastern border of the Project. No construction activities are anticipated to impact Swamp lake. Impacts will be minimized by the inclusion of a stormwater pond to detain and settle stormwater prior to entering Swamp Lake. Also, a parkland buffer between residential lots and the edge of the wetland is planned. County Ditch No.9, nearly bisects the southern half of the Project site with an arm extending northward to the northern border of the site. Recent maintenance on County Ditch No.9 has removed many of the trees and vegetation formerly lining the ditch bank. The Project will cross the County Ditch No.9 and impact the Ditch banks. Efforts will be made to avoid, and minimize impacts to the existing wetlands. Impacted wetland are limited to less than 4% of the total on-site wetlands and will be mitigated at a 2:1 ratio on-site. Further discussion of on-site wetlands is included in Section 12. Existing patches of woodland will be converted to residential uses. However, efforts will be made to incorporate as many of the existing trees as possible into future residential lots. The remainder of the Project site is currently agricultural. While agricultural land does represent a wildlife resource, it is a more seasonal and less valuable resource than wetlands. Furthermore, the conversion of agricultural land to residential is compatible with many forms of wildlife. The are no fish resources on or near the site that could be affected by the Project.

PHYSICAL IMPACTS ON WATER RESOURCES The residential development will be consistent with the existing wetlands and current wetland regulations. The field drainage ditches that are part of the on- site wetlands will be crossed at seven locations. Approximately 1.5 acres of Types 1 and 6 wetland of the existing 43.97 acres of on-site wetlands will be filled with approximately 1750 cubic yards of native material. Minor alteration of four existing drainage ditches located on the property will accommodate and enhance the overall stormwater and water quality controls. Wetland replacement will occur on-site at a ratio grater than the 2:1 ratio described in current wetland mitigation laws. No physical or hydrological alteration of the surface waters will occur outside the Project area. Stormwater detention and water quality ponds will be constructed that will control stormwater outflow rates and will be designed in accordance with applicable stormwater quality criteria. Section 13. WATER USE a) No wells are listed on the Minnesota County Well Index on the Project site. However, it is likely that wells dug prior to 1974 occur at each of the farmsteads located on the Project site. If wells are encountered they will be abandoned and sealed in accordance with Minnesota Department of Health requirements. c.) The Project will receive water for domestic and fire protection purposes from the Joint Powers Board System for Albertville, St. Michael and Hanover. The DNR water appropriation permit numbers for the supply are 146359 and 455787. Estimated daily water consumption for each Phase of the Project are found in the following table. Phase Number persons per Water Use rate Average Consumption of Lots residence (per Capita) (gallons per day) Phase I 43 2.7 100 11,610 Phase II 146 2.7 100 39,420 Phase III 158 2.7 100 42,660 Total 347 93,690 I I I I I I I I I I I I I I I I I I I The completed Project is 93,690 gallons per day based on an average of 2.7 persons per residence and typical water use rates of 100 gallons per capita per day (gcd). Section 18. WATER QUALITY - SURFACE WATER RUNOFF a.) The quantity of runoff from the Project is not expected to increase from present conditions nor is the quality expected to be adversely affected. These estimates are based on standard runoff parameters for the soil cover conditions that presently exist on the Project site and the soil cover conditions and impervious areas that are expected to exist upon Project completion. Water discharge quality is expected to improve upon Project completion and construction because of the use of stormwater detention ponds. Surface water runoff from storm events will discharge to County Ditch No.9, Swamp Lake, and the southern wetland after being controlled for rates and quality by means of control structures placed in existing ditches, stormwater detention ponds, and grassy swales. None of the stormwater runoff from the Project will be discharged directly into protected lakes, streams or County Ditch No.9. b.) Runoff from storm events will be routed into stormwater detention/water quality ponds and existing wetlands prior to controlled discharge into County Ditch No.9, the Crow River, and downstream waters. Phase I of the project calls for surface water runoff to enter existing ditches, stormwater piping, constructed stormwater detention ponds, and enhanced wetlands prior to entering the centrally located large wetland. The second phase of the Project will make use of the existing ditches, stormwater piping, and three stormwater drainage ponds to detain runoff prior to entering the centrally located wetland. The water discharge rate from the wetland to County Ditch No.9 will be controlled. Included in this Phase are an additional two stormwater ponds designed to detain runoff prior to overland discharge to County Ditch No.9. The Phase III of the Project will make use of the stormwater piping, two stormwater drainage ponds, and enhanced wetlands to detain runoff and control the discharge rate into County Ditch No.9. Surface water runoff in the eastern portion of the Project will be detained in two storm water ponds prior to entering Swamp Lake. Surface water runoff from the most southern lots will drain over the grassy lawns and swales into the southern wetland. The rate of discharge into County Ditch No.9 will not increase as a result of the Project. Stormwater from the Project enters the stormwater I I I I I I I I I I I I I I I I I I I detention/water quality ponds through storm sewer piping and overland flow. The Project is not expected to degrade stormwater quality when compared to existing conditions. Currently, the majority of the Project site is utilized for agriculture. Runoff from these areas are likely contains silt, pesticides and nutrients used in fertilizers such as nitrogen and phosphorus. Runoff from the completed Project may contain some pesticides and nutrients from lawn fertilizers and may contain some sediments from streets and yards. However, the detention/water quality ponds will provide a mechanism for sediment deposition and the attenuation of nutrients. Thus, suspended solids and nutrient inputs to County Ditch No.9 should be reduced by the construction of the Project. Section 19. WATER QUALITY - WASTEWATERS a.) All wastewater from the Project will be domestic sewage. Project estimates for wastewater generation can be found in the following table. The Average Wastewater Generated gallons per day are based on an average of 2.7 persons per residence and a flow rate of 100 gallons per day. Phase Number persons per Wastewater Generated Average Wastewater of Lots residence (per Capita) Generation (gallons per day) Phase I 43 2.7 100 11,610 Phase II 146 2.7 100 39,420 Phase III 158 2.7 100 42,660 Total 347 93,690 The wastewater generated from the Project will not include any industrial augmentation. The area to the south, once developed, can be expected to generate a similar residential flow rates. b.) No on-site wastewater treatment will be part of the Project. All of the Project sewer lines will be connected to the Albertville Wastewater treatment facility. The current facility consists of a pond system that provides secondary to tertiary treatment to remove phosphorous prior to discharge to Mud Lake. This facility is designed to treat 315,000 gallons per day with a CBOD loading of 368 pounds per day. Phase I of the project proposes an average daily wastewater of 11,610 gallons per day. Therefore, the current wastewater facility has the capacity to accommodate Phase I of the project. Phase II and Phase III wastewater flow amounts will occur after the Albertville waste water treatment facility is expanded. I I I I I I I I I I I I I I I I I I I c.) Currently the treatment facility averages 225,000 gallons per day and is expanding their treatment capabilities. The expansion is in the design stage with construction to begin in 2000 and additional capabilities are projected to be functional in 2001. Currently the facility has the potential to accommodate an additional 90,000 gallons per day and future plans, on file with the MPCA, indicate the facility design can be modified to treat a significantly higher flow rate and organic loading. It is estimated that the facility treatment can be increased to accommodate an average daily flow of 1,373,000 gallons per day with a CBOD loading of 2,380 pounds per day. The Albertville waste water facility has the current capability and will have the future capability to accommodate the additional wastewater flow from the Project and adjacent areas. Section 22. TRAFFIC Estimated total Average Daily Traffic (ADT) generated see table The following table express the projected average daily traffic on CSAH 118 from this project through the proposed Phases. It is anticipated that the majority of traffic will use CSAH 118 to access Interstate-94 to commute to the Twin Cities, however, local traffic does not need to use this route to access the local comm uni ties. Phase Number Daily trips per Daily Use of Lots residence Phase I 43 10 430 Phase II 146 10 1,460 Phase III 158 10 1,580 Total 347 3,470 Section 30. RELATED DEVELOPMENTS; CUMULATIVE IMPACTS c.) Development is anticipated on the adjacent property to the west and south of the Project in St. Michael, Minnesota. However, the planning and schedule for this development is unknown. The impact of these developments cannot be determined at this time.
