Approval is also subject to the City Council ordering the Capital Improvement Project #92 -5 for trunk utility improvements. FINAL PLAT REQUEST Lundgren Brothers is requesting final plat approval for the first phase of the Meadows at Longacres previously known as the "Johnson - Dolejsi- Turner" property. The preliminary plat approval was given in October of 1992 and an extension of the PUD was given a year later. The preliminary plat has been revised to accommodate the acquisition of the Song property and the subsequent plat. The first phase of this plat proposed access from Highway 41. Meadows at Longacres Final Plat Page 6 This subdivision was iven numerous conditions of approval with the preliminary plat, based on g PP P �Y P ' the scale of the development, sensitive of the natural features and the use of the PUD zone. Staff has reviewed these conditions to determine which ones apply to this phase, which ones have been met and which ones still need to be carried forward with this phase of the final plat. ' The applicant is proposing to final plat 38 lots with 12 outlots. Following is a list of the proposed outlots: ' Outlot A Wetland Mitigation Area Outlot B Wetland ' Outlot C Entry Gateway Outlot D Existing site of the Turner Auto Repair to be removed and will be entry gateway Outlot E Partially wetland and partially a storm pond with the remaining portion of the lot a park Outlot F Future drive access to the Weathers property Outlot G Future Development Phases ' Outlot H Future Development Phases Outlot I Future Development Phases Outlot J Future Development Phases ' Outlot K Future Development Phases Outlot L Future Development Phases One of the purposes of applying the PUD zone was to give flexibility to the development standards in order to provide for the preservation of natural features. A cul -de -sac was eliminated from Block 1 replaced with a private drive that will serve three lots. As a part of the 1 preliminary plat, front yard variances were given to reduce tree removal or increase setbacks from wetlands. Front yard variances are recommended for 10 lots (See Lot Tabulation Attachment). ' One half of the lots abut wetlands. All wetland lots will have a buffer strip and will be posted with a buffer monumentation sign. (See Lot Tabulation Attachment). LANDSCAPING ' One of the conditions of the preliminary plat approval was a landscaping/streetscape plan. Gene Ernst of Ernst and Associations had prepared a landscaping plan. This plan proposed landscaped entry monuments on either side of the entrance off of Highway 41 as well as a planter island. ' Landscaping in these areas include existing deciduous with the addition of'52 Austrian Pines. Seventeen of the pines will be located between Highway 41 and the private drive to screen the lots adjacent to Highway 41 in Block 1. Streetscape along Longacres Drive include substantial stands of existing and deciduous trees with the additional planting of 8 sugar maples and 9 ash trees. 1 1 Meadows at Longacres Final Plat Page 7 PARK AND RECREATION This plat proposes a private neighborhood park, a trail along Highway 41 and adjacent to the wetland located on the southern edge of the plat. The park will include an informal play area and a play structure. The Park and Recreation Director has reached an agreement with Lundgren Brothers Construction that they will act as a general contractor for the city in regard to the construction of the trail (which has been specified as an asphalt trail to be constructed per standard city specifications). Lundgren Brothers will solicit a minimum of three bids for the , construction of the trail for presentation to the Chanhassen City Council. The council may elect to accept a qualifying bid or reject all bids in favor of constructing the trail under a separate contract. In the event that Lundgren Brothers coordinates this work, the city, upon completion , and acceptance of the trail, will pay Lundgren Brothers Construction the full contract amount. This payment would be made from the city's trail acquisition and development fund. Under this arrangement, the city would collect full trail fees in addition to park fees for both the Meadows ' at Longacres and the Song property plats. The complete conditions of approval regarding parks and trails for the Meadows at Longacres ' shall read: 1. Full park and trail fees shall be paid per city ordinance. ' 2. Lundgren Brothers Construction will act as the city's general contractor, soliciting bids for construction of an 8 ft. wide asphalt trail as depicted on the applicant's grading and drainage plan dated March 1994. The trail segment north of Longacres Drive at Highway 41 shall be the only exclusion. Final alignment of this trail shall be staked by the applicant and approved by the Park and Recreation Director and City Engineer. This trail shall be constructed per standard city specifications and must maintain a minimum separation of 10 ft. from the wetland delineation. A minimum of three bids for the ' construction of this trail shall be presented to the city for consideration by the Chanhassen City Council. The council will elect to accept a qualifying bid or reject all bids in favor of rebidding the work under city contract. In the event that a bid is accepted, Lundgren Brothers Construction will coordinate this work as a part of the first phase of public improvements. Upon completion and acceptance of the trail construction, the city will pay Lundgren Brothers Construction the full amount for said construction. ' 3. All easements for trail purposes necessitated by this construction shall be granted to the city for recording. The minimum width of said easements shall be 20 feet. , UTILITIES The subdivision will be receiving san sewer and water service from the City's trunk sanitary , g �' tY �'Y sewer and watermain project (No. 92 -5). The City will be installing the 16 -inch watermain along I LI Meadows at Longacres 1 Final Plat Page 8 ' Longacres Drive and the development will be assessed accordingly. The City is also extending sanitary sewer service to the site and constructing a lift station at the very easterly end of Moccasin Trail. At that point the developer will install the remaining sewer lines within the ' development. The plat is proposed to be assessed for the trunk sanitary sewer and water improvements (trunk and lateral) in accordance with the feasibility study. The developer and/or property owners shall waive any and all procedural or substantive objections to the special ' assessments including, but not limited to, hearing requirements and any claims that the assessment exceeds the benefit to the property. ' The applicant has supplied the City with detailed utility and street construction plans and specifications which are also being considered for approval at this time. Staff has reviewed the plans and specifications and finds them in general conformance with City standards and detail I plates. Some minor revisions are still pending on the construction plans. However, staff feels that they can be worked out fairly easily with the developer's engineer. ' The applicant is providing an individual sewer and water service to Outlot F for future service to the exception parcel (Weathers'). The developer should be given a refund or assessment credit for the installation of the sewer and water service to Outlot F when the property owner connects i to the individual sewer and water service. This is consistent with other developments in the City ■ where the applicant has provided sewer and water service for the adjacent parcels which, at the time, were not interested in connecting to. One of the other conditions in the preliminary plat ' approval was for the applicant to extend sewer and water service north of this development. This will be accomplished with a future phase. The existing business which was on Lot 1, Block 1 of the preliminary plat has not been demolished yet. The final plat represents this lot as Outlot D. There is also an existing home on Lot 4, Block 2. This home was previously on a septic and well system. The septic system will have to be abandoned in accordance to City and State codes. ' The existing home should be required to hook up to the sanitary sewer system within 30 days after the lines are accepted by the City. The existing well on the property may be utilized until the well fails and then connection to the City's water system would be required. Utility service to Lots 1, 2 and 3, Block 1 will be by injector pump due to the elevation difference. Staff felt this was the most feasible way to service these lots. The other alternative ' would have been to construct the sanitary sewer line in Longacres Drive much deeper (30' +). GRADING AND DRAINAGE The applicant has submitted a final grading, drainage and erosion control plan for approval. The revised plans have incorporated staff's recommendations. There are still some minor adjustments ' necessary on the grading and drainage plan such as an emergency overflow, adjusting a house pad elevation, etc. The scope of the work will include grading for this first phase of The Meadows at Longacres including the entire length of Moccasin Trail in order to facilitate construction of the lift station and sanitary sewer lines. Lots outside of the plat along Moccasin Meadows at Longacres Final Plat Page 9 Trail will not be developed at this time. The plat is also dedicating Longacres Drive and Hunter , Trail to the east property line. The streets will not be constructed east of Lot 1, Block 5; however, the City is installing utilities along the right -of -way. The applicant is proposing to fill approximately 2.8 acres of isolated wetlands at nine locations. The applicant has received the necessary permits from the Army Corps of Engineers back in October of 1993. Therefore, their mitigation measures are 1:1. However, the developer is ' actually creating or expanding four wetlands at four separate locations having a total acreage of approximately 3 acres. One of the previous conditions of the preliminary plat was for the applicant to show the setbacks and wetland buffer edges on the grading plan. The applicant has ' shown the setbacks as drainage and utility easements on the final plat. This will be easier for the individual homeowners to obtain a copy of to determine their actual setback requirements. In addition, the City, under the new ordinance, will be requiring that wetland monumentation , signage be installed on every other lot line at the buffer edge. The applicant will be charged a fee of $20 per sign accordingly. Conservation easements and tree preservation easements will be provided over the applicable areas. These easements will be recorded with the final plat. , Staff would still like to have wetland buffer setbacks shown on the grading plan. The storm water management plan for this phase of the Longacres project will include construction of a storm drainage pipe system as well as four water quality or NURP basins. NURP Basin No. 2 will utilize a portion of a low - quality wetland located along the north side of Longacres Drive. NURP Basin No. 3 is proposed to be built adjacent to a natural wetland. ' According the City's ordinance, a native vegetative buffer strip 10 feet in width shall be maintained around natural wetlands. This will limit grading to within 10 feet of the wetland. The applicant's grading plan will have to be revised to reflect this requirement. Storm water runoff is being conveyed to the NURP basins. The basins overflow into the wetland areas. The wetland water level is controlled by a storm sewer outlet pipe. Staff is concerned that the predeveloped flood bounce in these wetlands be maintained. The applicant will have to submit ' to the City for review and approval the predeveloped runoff conditions to each one of the wetlands on this site and adjust the storm sewer outlets to maintain the predeveloped flood levels in each wetland. Staff still has not received detailed storm sewer calculations for the individual segments of storm sewer on the site. These calculations must be submitted to staff for review and approval prior to the City formally approving the construction plans. The detailed storm , water calculations shall be designed to handle a 10 -year storm event based on the rational method. The project will be complying with the City's water quality standards and therefore no surface water management plan (SWMP) fees for water quality will be required. However, depending on the storm ponding calculations, if the development is not meeting the City SWMP for water quantity, then the applicant will be required to contribute into the City's SWMP program. The proposed rate per acre for single family is $1,980 /acre. Meadows at Longacres Final Plat Page 10 Upon review of the construction plans and final plat it appears a few additional drainage and ' utility easements should be provided on the final plat to cover drainageways or utility lines. These areas will be listed in the conditions of approval. STREETS The major thoroughfare, Longacres Drive, is designated as an east/west collector street providing ' future connection from Trunk Highway 41 to Galpin Boulevard. This segment of roadway is also listed on the City's MSA system. The applicant has submitted detailed street construction plans to MnDOT's State Aid office for review and approval. It is necessary to receive at least ' preliminary approval on the street alignment from MnDOT prior to having the final plat approved and recorded at the County. Staff believes that the street alignment will meet the State's design criteria; however, should the State request a modification the applicant should be required to comply with their requirements. One requirement already noted was that the developer shall provide a full -time inspector on the project. The inspector will need to be state - certified as well. ' Longacres Drive will be built 36 feet wide face -to -face within a 60 -foot wide right-of-way. A 5 -foot concrete sidewalk is proposed along the north side of the roadway. The other streets will be the City's standard urban section (31 feet). This phase also proposes a series of landscaped islands in the cul-de -sac as well as the center median on Longacres Drive at the Trunk Highway 41 entrance. Staff has been working with the applicant to develop an island design that works from a snow plowing and public safety standpoint. Upon review of the island design with the City's Fire Marshal, based on actual field tests a fire truck will not be able to maneuver in the cul -de -sac with the islands without jockeying back and forth. If a car is parked either on the ' outside curb line or adjacent to the island the truck would not be able to accomplish that movement. Therefore, the Public Safety Department has recommended that these cul -de -sac islands, as well as the cul -de -sac, be posted for no parking. The applicant has expressed some 1 concern with this requirement since the residents will likely want to utilize the area for parking. The other landscaped island on Longacres Drive at the entrance from Trunk Highway 41 will be heavily landscaped. The applicant has developed a very extensive landscaping plan along Trunk Highway 41, especially at the entrance point to the subdivision. The islands will be maintained by the homeowners association through the means of declaration of covenants. ' The applicant is proposing to serve Lots 1, 2 and 3, Block 1 from a private driveway off of Longacres Drive. Staff has worked with the applicant to design what we feel is the best alternative to this situation to minimize impact to the area. A driveway or cross- access easement across Outlot C, Lots 1, 2 and 3, Block 1 will be necessary between the property owners. The exception parcel adjacent to Outlot F currently takes access from Trunk Highway 41. As L you are aware, Trunk Highway 41 is a fairly heavily travelled street. At some point the access to this site may be eliminated by MnDOT. This phase of the development through Outlot F does provide a means for ingress and egress to the exception through Outlot F. Staff has worked with Meadows at Longacres Final Plat , Page 11 the applicant to convey Outlot F to the City for future driveway purposes to the exception parcel. ' Therefore, a warranty deed for Oudot F should be conveyed to the City in conjunction with final platting of the subdivision. Another requirement with the preliminary plat approval was for the applicant to provide street access to the north. This condition is not applicable to this phase. ' The construction plans provide for deceleration and acceleration lanes as well as a bypass lane on Trunk Highway 41. The applicant has been working with MnDOT on the access control as ' well as design of the auxiliary turn lanes. Street grades in the subdivision range from 0.5% to 7.0% which is in accordance with the City codes. The applicant is providing a temporary cul -de- sac at the end of Longacres Drive with barricades and signs indicating that this street will be ' extended in the future. Staff also recommends that a condition be placed in the development contract indicating that Longacres Drives, as well as Moccasin Trail, will be extended in the future. I Staff previously reviewed the street names for this phase of the development. The Public Safety Department requested that street names on the final plat for Southview Court and Hillside Court ' be revised. The applicant has provided two new names, Southern Court and Hillsdale Court, which are acceptable to Public Safety. These names, however, have not been transferred onto the final plat and will need to be prior to recording. As previously mentioned, the final plat ' should be contingent upon MnDOT's State Aid office giving preliminary approval - for the alignment of Longacres Drive from both a horizontal and vertical alignment standpoint. This is necessary to insure the property right -of -way or easements have been conveyed for the ' construction of the roadway system. Staff does not believe the alignment will change, at least not significantly; therefore, we recommend granting approval to commence site grading prior to recording of the final plat conditioned upon the applicant executing the development contract and providing the security to guarantee installation of the public improvements. An extensive trail system is proposed to be built by the applicant and financed by the City's Park and Recreation budget. The Park and Recreation Director has been working with the applicant to develop the system adjacent the southerly wetlands on the site. The appropriate trail easements will need to be conveyed to the City in conjunction with filing of the plat. The minimum width of the trail easement shall be 20 feet. SUBDMSION , (Rezoning) I 1.

As a part of this review, I held .two phone conversations with Mr. Mike Pflaum of Lundgren Brothers Construction in regard to the .construction of the trail component of this development. We have reached an agreement that Lundgren Brothers Construction will act as a general contractor for the city in regard to the construction of the trail (which has been specified as an asphalt trail to be constructed per standard city specifications). Lundgren Brothers will solicit a minimum of three bids for the construction of the trail for presentation to the Chanhassen City Council. The council may elect to accept a qualifying bid or reject all bids in favor of constructing the trail under # I separate contract 'In the event that Lundgren Brothers coordinates this work, the city, upon completion and acceptance of the trail, will pay Lundgren Brothers Construction the full contract amount. This payment would be made from the city's trail acquisition and development fund. Under this arrangement, the city would collect full trail fees in addition to park fees for both the Meadows at Long Acres and the Song property plats. The complete shall read: Long Acres t 1.

PC: Don Ashworth, City Manager Dave Hempel, Assistant City Engineer Roger Knutson, City Attorney Lundgren Brothers Construction LL RP v LunDGREn 01 March 11, 1994 CONSTRUCTION • Paul Krauss INC. Chanhassen Planning Director 690 Coulter Drive Chanhassen, MN 55317 I Dear Paul: 935 E. Wayzata Blvd. As you know, Lundgren Bros. has for some time been attempting to "fine tune" this Wayzata large and complicated project. Today, Schoell & Madson submitted the final plat and Minnesota 55391 grading plan for the first development phase of The Meadows at Longacres. I am sure (612)473 -1231 I will not be alone in my pleasure at finally being able to abandon the "Johnson-Dolejsi- Turner" moniker! The Meadows at Longacres (lot numbers refer to final plat) Wetland Protection. The attached "Johnson - Dolejsi -Turner Site Lot Tabulation" was prepared by DSU and included in the Preliminary Plat submission. It should be noted that this tabulation (and the subsequent approval of the JDT Preliminary Plat) preceded the most recent amendment of the City's Wetlands Ordinance. The principal structure setback which was proposed by Lundgren Bros. and approved by the City is 30 feet from the upland edge of the wetland buffer strip. The DSU Lot Tabulation does not measure setback in the same manner as the new Wetlands Ordinance. The column captioned "Wetland Setback" contains the minimum principal structure setback from the edge of r the wetland, not the wetland buffer strip. Trails. This topic was discussed at some length in our meeting with Staff on 2/17/94. The Trail along Highway 41 is a standard City trail. It will be 8 feet wide and have a bituminous surface. Lundgren Bros. suggested that the easement for this trail be reduced from 20 feet to 10 feet where the trail passes between the project's entrance landscaping ' and the highway ROW in Outlots C and D. The City wants to retain the 20 -foot The following is largely a recitation of concurrences which I believe Lundgren Bros. and the City Staff have reached in our several recent meetings on this project. It contains in addition items which we have not yet discussed and one or two items which may require action by the City Council. Understanding that you regrettably soon will be leaving Chanhassen and that you are also the most knowledgeable in this project at the City, I am requesting that you now take a few moments to review this narrative and comment on my statements and requests as you deem appropriate. I know you can appreciate how important it will be to us and your successor, that we document our current understandings as carefully as possible. The Meadows at Longacres (lot numbers refer to final plat) Wetland Protection. The attached "Johnson - Dolejsi -Turner Site Lot Tabulation" was prepared by DSU and included in the Preliminary Plat submission. It should be noted that this tabulation (and the subsequent approval of the JDT Preliminary Plat) preceded the most recent amendment of the City's Wetlands Ordinance. The principal structure setback which was proposed by Lundgren Bros. and approved by the City is 30 feet from the upland edge of the wetland buffer strip.

This topic was discussed at some length in our meeting with Staff on 2/17/94. The Trail along Highway 41 is a standard City trail. It will be 8 feet wide and have a bituminous surface. Lundgren Bros. suggested that the easement for this trail be reduced from 20 feet to 10 feet where the trail passes between the project's entrance landscaping ' and the highway ROW in Outlots C and D. The City wants to retain the 20 -foot Mr. Paul Krauss March 11, 1994 Page 2 easement, but will allow landscaping improvements within the easement. Lundgren Bros. stated that it would, with the development of Phase 1, construct this trail where future paving would disrupt the landscaping in Outlots C and D, and would grade the trail bed elsewhere for future installation by the City. The City suggested that it would be better if Lundgren Bros. constructed all of this trail with the development of Phase 1. Lundgren Bros. stated that it would be willing to do this work, but should be reimbursed for its cost as soon as the trail is paved. Not discussed was the section of the trail which is adjacent to Lots 6 and 7, Block 4. There is no trail yet north of these lots, and the Oas parcel creates a gap to the south. It may be best to prepare a base for this, but to leave it unpaved until the City is ready to construct the trail northward from Outlot D. The trail eastward from Hi hwa 41 along the south property line, is to be 8 feet wide and constructed with an aggregate, not a bituminous surface. The trail will be constructed within a trail easement owned by the City and be as close to the edge of the wetland as is practical. The trail may be constructed in the wetland buffer strip. The location of the trail and of its connection to Moccasin Trail (formerly, "B" Street) is acceptable to the City, but the trail will have to be staked and field approved prior to construction. The City , said it has no objection to our trail easements' prohibiting motorized vehicles other than those owned by the City and used for maintenance and public safety. Lundgren Bros. again asked how it was to be compensated for constructing the trail. The cost of this trail will exceed the trail fees for The Meadows at Longacres, the remainder of the JDT Project and probably the Song Project as well. Lundgren Bros. proposed that it not be required to pay Trail Dedication or Park Dedication fees for either Project until it has full credit for the cost of constructing this trail. The City said that since Park Fees and Trail Fees are placed in separate accounts, it would be necessary for the City Council to approve such a plan for compensation. Lundgren Bros. believes that the fairest and most easily administered handling of this would be for the City to pay Lundgren Bros. the cost of each section as it is completed, and collect Park Fees and Trail Fees as it normally would. Reduced Front Yards. Lundgren Bros. and City Staff have concurred that 20 foot front yards should be allowed to reduce tree removal and/or to increase principal structure setback from wetlands for the following The Meadows at Longacres lots: Block 1 Block 3 Lot 6 Lot 5 Block 2 Block 4 Lot 1 Lot 5 Lot 8 (Moccasin Trail frontage) Lot 6 Lot 13 (Southview Court & Moccasin Trail) Lot 7 Mr Paul Krauss suss March 11, 1994 Page 3 Other Setbacks. The buildin g � setback from the Oas ) Exception Parcel will be 10 feet for P Lot 5, Block 3 and Lot 7, Block 4. New: To avoid possible confusion, the homes to be constructed on the common private driveway (Lots 1 -3, Block 1) should be deemed to "front" on Highway 41, which is the direction which the homes will face. This means there will be a minimum building setback of 10 feet from the north line of each of these lots. Recreational Outlot. The basketball half -court will be removed from the plan to provide more open, informal play area; the play structure will be moved toward the center of the outlot; and the pond will be moved to the west to provide a buffer for the neighboring lot owner. Landscaping. Visual buffering of the homes on Lots 1 -3, Block 1 from Highway 41 will ' be accomplished by berming and planting clusters of evergreens along the common private driveway which is their access. Lundgren Bros. presented a plan showing the buffering elements and the City concurred that they satisfied the requirement. The hammerhead turnaround will have to be reviewed by Public Safety, but the concept of using this instead of the loop previously shown was approved. The boulevard planting plan for "A" Street was accepted by Staff, subject to Public Works and Engineering confirming the width of the sidewalk, the required spacing between the sidewalk and the curb, and the required spacing between the sidewalk and the boulevard trees. Engineering has since confirmed that the sidewalk should be approximately 5 feet behind the curb, and the trees should be approximately 4 feet behind the sidewalk. This will place the tree 2 feet inside of the lot. On the opposite side of the street, the tree would be 10 feet behind the curb, which is 2 feet inside of the ROW. The landscaping of the entrance area was depicted on a separate plan. While there remain questions about State Aid standards and other engineering requirements, the landscaping design for the entrance area was acceptable. If the State does not object, a lighted entrance monument will be placed on the median, and the median will be as wide as possible to maximize the separation of the incoming and outgoing lanes. Landscaping will be permitted in the easement to be provided for the Highway 41 trail. Revised Preliminary Plat dated 3/8/94 The attached 'Revised Preliminary Plat" shows how changes required by the Johnson - Dolejsi -Turner preliminary approval and the preliminary approval of the Song plat have been accommodated. The Revised Preliminary Plat also adds one lot (Lot 76B, Block 2) to the previous total for the area it represents. However, since The Meadows.at Longacres contains one less lot than was in preliminary plat Block 5, there is no net change. For consistency and ease in comparison, we have attempted to follow the same Lot -Block numbering scheme as on the approved preliminary plat. Mr. Paul Krauss March 11, 1994 Page 4 In the Revised Preliminary Plat area, there are a number of lots where required design modifications, avoidance of impacts on natural features and better setback continuity recommend consideration of additional front yard reductions. These candidates are listed and described below: Block 2 Block 3 Lot 20 Lot 1 Lot 21 Lot 2 Lot 32 Lot 64 Block 4 Lot 75 Lot 5 Lot 76A Lot 7 Lot 77 Inclusion Lots 20, 21 and 32 offers opportunities to reduce grading impacts on trees and will provide better continuity of streetscape, since the adjacent lots are approved for the reduced front yard. Lot 64, while buildable with the standard front yard, likewise lies , between lots having the reduced front yard and will fit better if it has the same setback. Lots 75 and 76A are on a wooded, rapidly falling hillside which will be less impacted by grading if the homes are closer to the street. Lot 77 should be treated the same as Lot 78, where a reduced front yard was granted to save trees. Lot 1, Block 3 bisects a wetland which will benefit from 10 feet more separation from the dwelling. Lot 2, Block 3 would similarly benefit. Lot 5, Block 4 needs additional depth along its north -south axis because it adjacent to the project boundary. A 20 -foot front yard on the cul de sac will permit additional structure setback from this boundary. Lot 7, Block 4 backs up to the same wetland as Lot 1, Block 3 and should be considered for a reduced front yard for the same reason. Flap, Lot Lot 76B, Block 2 was created because the additional street frontage created by ' extending "F" Street to the Song Property affords access to the abundant area at the rear of approved Lots 36 and 75, Block 2. The driveway would follow the sanitary sewer forcemain through the power line easement. On this lot, the yard to the east of the dwelling should be designated the front yard i Paul, I hope this has been reasonably clear, accurate and not too trying of your patience. Please call if you have any questions or require further elaboration. Naturally, what Mr. Paul Krauss March 11, 1994 Page 5 Lundgren Bros. would most appreciate is a letter which would communicate your views on these matters.

Wayzata Blvd. Re: Landscaping Plans for The Meadows at Longacres Wayzata Dear Kate: Minne Minneso 55391 , Minnesota As you are aware, conditions of the preliminary approval of Johnson /Dolejsi/Turner require that Lundgren Bros. provide as part of its final plan submission landscaping plans which address buffering of the view of homes from Highway 41 and proposed boulevard plantings along the collector street (Longacres Drive). Ernst Associates of Chaska has prepared such plans, and they were submitted today with the engineering plans prepared by Schoell & Mad - son. The plans are essentially identical to those we reviewed with Paul , Krauss, Todd Hoffman and Dave Hempel on February 17, 1994. The boul- evard plan incorporates Dave Hempel's setback standards for the plantings and the sidewalk. Our buffering plantings proposal builds upon the natural vegetation wherever possible. The homeowners association owned entrance outlots will be heavily planted in very large evergreens which will virtually obscure the most westerly homes on Longacres Drive. Replacing the cul de sac which originally was to extend southward from Longacres Drive has two positive benefits: It reduces from six to three the number of homes which will be exposed to the Highway, and it increas- es the distance between the homes and the Highway. Since the homes on the common private driveway will face Highway 41, only two living levels will be viewable. The berms and plantings the Ernst plans show do not obscure these homes, but they will break up their shapes and soften and enhance the view. Lots 6 and 7, Block 4 have been improved by moving the Hilltop Court cul de sac eastward, and there is a substantial thicket of small trees along the Highway which we intend to preserve. However, since the Highway is 10 -16 feet higher than the proposed grade at the rear Ms. Kate Aanenson April 8, 1994 Page 2 of these homes and the drop -off from the roadway is so abrupt, we do not believe that further buffering can effectively be done. ' Kate, I hope this amplification of the Ernst Associates plans is useful. Please call me if you have any questions or require further information. 1 Very truly yours, LUNDGREN BROS.
