DISCUSSION Staff has reviewed the application and site plan submitted by the applicant and recommends that the public hearing be continued to the July 25th meeting in order to allow the applicant additional time to resolve the issues as stated below. a) The access arrangement off of 4th Street to a proposed rear entrance across the Canadian Pacific Railroad ROW does not appear to be authorized in the contract between Mr. Steve Finden and SOO Line Railroad Company. The contract terms state in paragraph 9(b) that Mr. Pinden leases the portion land lying 9.5 feet of the either side of the centerline of the track. Staff requests the exhibits that identify the areas mentioned in paragraph 9(a) of same contract and a written permission from the railroad company to allow for the proposed use(s) of the right-of-way. b) Staff originally identified that a portion of the lot that the applicant proposes to utilize is within both an existing unimproved alley that runs east-west in Block 30 and also encroaches along the railroad right-of-way. Staff notes that a survey submitted by the applicant identifies the alley to be vacated; staff will follow up with City documentation. Staff also recognizes that the Pine Street right-of-way has not been officially vacated according to records dating back to 1950. Staff points out that the property comer is located just to the north side of the centerline of the 100- foot railroad ROW. c) Staff also requests that the applicant submit a survey along with a site plan indicating . the location of proposed structures, driveways and possible screening. ACTION REQUESTED Continue the public hearing to the next scheduled Planning Commission meeting to allow the applicant additional time to submit requested information.

The property was rezoned to R-3 PUD High Density residential on January 3, 2000. A negative declaration, stating that the project does not have potential significant environmental effects that warrant the preparation of an Environmental Impact Statement was accepted by the City Council on July 3, 2000. The proposed development consists of 94 detached residential units and 283 attached residential units. Plannine: Division Review Applicant: Rottlund Homes J. Michael Noonan, Division Vice President 3065 Centre Pointe Drive Roseville, MN 55113 (651) 638-0520 jmnoonan@rottlundhomes.com Referral Comments: 1. City Engineering Division 2. Dakota County Soil & Water Conservation District Attachments: 1. Location Map 2. Letter from Developer 3. Application for Plat Review 4. Plat Information Location of Property: Southeast quadrant of the intersection of CSAH 31 (Pilot Knob Road) and CR 64 (195th Street West). Area Bounded By: Single-family residential on the east, agriculture on the south, vacant on the west and an elementary school on the north. . . . Existing Zoning: R-3 PUD High Density Residential Proposed Development: The Developer proposes 377 housing units constructed on approximately 122.5 acres. The proposed building types are as follows: Single-Family - Gardens Garden Townhomes Villa Townhomes 94 units 68 units 67 units 148 units The single-family product proposes ramblers, split- levels and two-story configurations. The gardens are slab on grade construction and provide one-level living and consist of 4-unit buildings. The garden townhomes include a basement. The two-story villa townhomes consist of 8 or 12-unit buildings. Streets and Accesses: The Developer proposes three accesses from the property. One access onto Pilot Knob Road to the west, a second access onto 195th Street to the north (Street A) and a third access onto Akin Road to the east (Street B). The Developer proposes both public and private streets. The private streets will be maintained by a homeowners association. Public Street Widths 40' back of curb to back of curb with 70' ROW 34' back of curb to back of curb with 60' ROW Private Street Widths 30' back of curb to back of curb 24' back of curb to back of curb 22' back of curb to back of curb Water, Sewer & Gas: Water access is located at the newly constructed City water tower and sewer will be available from the south through the Murphy Farm development. A 100-foot wide gas line easement runs north and south through the western portion of the site. No structures may be located within the easement. The Developer proposes to maintain a 10- foot building setback from the gas line easement. Sidewalks: A sidewalk has been proposed on the west side of the north/south (Street A) roadway and a 8-foot wide trail is proposed on the east side of Street A. 2 . . . Topography: Site topography is rolling except for the central portion of the site that tends to provide wider contours. The drainage patterns are generally towards the south. There is a large existing swale area along the eastern property line that abuts the homes along Akin Road. Wetland: The wetlands shown on the site are classified as protect wetlands. The largest wetland encompasses approximately 14.8 acres and the smaller wetland is approximately 5.6 acres in size. The protect wetland classification requires that structures shall not be placed within a minimum of 10 feet of the buffer area. The buffer area provides a minimum of 75 feet from a protect wetland, thereby requiring a minimum setback of 85 feet surrounding the entire wetland. These types of wetlands exist in a largely unaltered state and have special and unusual qualities that call for a high level of protection. Flood Plain: There are no flood plains delineated on this property. Parkland and Trails: The Developer proposes a park located on the peninsula between the two wetlands. A trail will be provided to access the park through the buffer area surrounding the wetlands as well as from the cul-de-sac at the end of Street D directly to the north of the proposed park. Additional Comments The Vermillion Grove PUD was approved by the City Council on January 3, 2000, re- designating the property to R-3 PUD. The PUD process permits any combination of the following uses: single-family, two-family, quad homes, town or row houses and apartments. The PUD requires that the total coverage by buildings shall not exceed twenty percent (20%) of the total area in the PUD. The total building coverage shown on the preliminary plat is 13.22 acres and the total plat area is 122.44 thereby providing 10.80% building coverage within the Vermillion Grove Preliminary Plat. Proposed Density The Developer proposes the following gross densities: Housing Type Proposed Density City Requirement Land Use Designation Single-Family 2.3 du/ac 1 to 3.5 du/ac Low-Density Gardens 3.9 dulac 2.5 to 5.5 du/ac LowlMedium-Density Villa Townhomes 7 dulac 5.5 to 14.0 du/ac Medium-Density The proposed gross densities correlate to the 2020 Comprehensive Plan Update. 3 . Transportation The Developer proposes three accesses from the property. The westerly access is proposed as a 70-foot right-of-way with a roadway width of 40 feet measured from the back of the curb to the back of the curb that connects to Pilot Knob Road. The roadway is shown as a future minor collector on the 2020 Thoroughfare Plan. A majority of the traffic is expected to enter and leave the property from this access, thereby requiring a left turn lane on Pilot Knob Road towards the south. The northerly access is shown as a 70-foot right-of-way with a roadway width of 40 feet measured from the back of curb to back of curb and provides a north/south transportation corridor (Street A) through the development. The proposed roadway will also provide a shared access with the City property to the west. This roadway is considered a public street and will be maintained by the City of Farmington. The City is negotiating a cost share agreement with Rottlund Homes for the construction of both this roadway as well as the roadway along the southern border of the City's property. The easterly access is shown as a 60-foot right-of-way with a roadway width of34 feet measured from the back of curb to back of curb that is proposed to connect to Akin Road. The Developer is in the process of acquiring a small piece of the Pettis property in order to connect the roadway to the right-of-way of Akin Road. This access will mainly accommodate vehicles travelling south on Akin Road into the subdivision and north on Akin Road, leaving the subdivision. The developer will be required to provide a right turn lane and a bypass lane on Akin Road. . The Developer has prepared a trip generation analysis for the development. In total, the Vermillion Grove development is expected to generate 2,500 average daily trips with the proposed 377 housing units. The trip generation model anticipates approximately 60% of site traffic will be distributed to the north on Pilot Knob Road (from the site via Pilot Knob Road and Akin Road) and approximately 20% will be distributed to the west via 195th Street. The remaining trips will be distributed to the south. Roadways associated with the villas and gardens will be private streets and will be maintained by a homeowners association. The widths of these roadways include 30-foot, 24-foot and 22-foot all measured from the back of curb to back of curb. Transportation Issues There are transportation issues that need to be addressed on the preliminary plat. As mentioned above, an agreement with the Pettis property needs to be finalized to connect Street B with Akin Road on the east. The phasing of the property will be from the west and no connection with Akin Road is proposed until after these phases are completed. . Secondly, all of the public cul-de-sacs (Streets C, D, E and N) proposed on the plat exceed the maximum cul-de-sac length of 500 feet as required in the City Code by 15 feet. Therefore, the Developer requests a variance to the maximum length of a cul-de-sac. City staff has reviewed the request and has researched surrounding communities for their maximum requirements. An average length for most communities is 700 to 1,000 feet. 4 . . . Additionally, the Fire Marshal has reviewed the cul-de-sac issue and has stated that ifthe cul-de- sac has an unobstructed lane of traffic 20 feet in width and an adequate turnaround radius, the Fire Department can accept a cul-de-sac length of 500 feet or more. Therefore, City staff recommends approval of the variance concurrent with the approval of the preliminary plat. During the zoning code update, staff will propose an update to the maximum length of a cul-de- sac. The third transportation issue consists of the turnaround radius for the proposed cul-de-sacs on Streets C, D, E and N and Drive H. The City standard requires a 66-foot right-of-way with a 50- foot radius to the face of the curb (no curb is required for Drive H). The cul-de-sacs are shown with a 60-foot right-of-way and 47 feet to the back of the curb. This issue needs to be addressed on the plat. Additionally, City staff recommends that the cul-de-sac roadways (Streets C, D, E and N) be reduced from 34-foot back to back streets to 30-foot back to back streets making the street pavement width 28 feet and requiring a sidewalk on one side of the street. Staff has made this recommendation for a 28-foot wide street upon the following criteria: 1. The functional classification of the roadway (i.e. local, collector) will be a primary consideration. 2. Proposed developments that reside near land that is environmentally sensitive including wetlands, floodways, slopes or natural areas to reduce pavement and runoff from large expanses of paved surfaces. 3. The reduction of road widths in areas where the presence of neighborhood parks and multiple driveways are being planned. 4. The need for sidewalks on at least a minimum of one side is required, however sidewalks on both sides of the street will be encouraged to enhance pedestrian safety. 5. The 28-foot roadway requires an 8-foot parking lane on one side and a 20-foot width for two-way traffic flow. 6. The development is part of a PUD where the preservation and enhancement of desirable site characteristics and open space are recommended. Benefits to the reduced street widths and sidewalk installation include improved pedestrian safety, increased traffic calming effects and may provide for a more cohesive neighborhood. City staff also recommends that the Developer propose a sidewalk or trail on one side of Street B in order to promote pedestrian safety in the single-family area and provide access to the north/south trail along Street A. The trail along Street A may then be utilized by the entire development for to access Akin Elementary School to the north, thereby alleviating some pressures to bus children in this neighborhood. The final transportation issue concerns the lengths of the dead end driveways of buildings 62, 63 and 64. The driveways along the west sides of these buildings show lengths exceeding the fire code requirement of a maximum of 150 feet. Therefore, the City's dead end access road policy (see attached) is required for the three driveways and needs to be addressed on the plat. 5 . . . Park & Recreation Issues The Parks & Recreation Commission has approved a park location on the peninsula between the wetland areas. A playground structure is proposed for this area. Additionally, a trail is required from the cul-de-sac on Street D to the park area. Trail locations surrounding the wetlands is being negotiated with the Developer. Secondly, the proposed 4-acres of park space along the easterly property line is not conducive to the park system due to the inability of accessing the site. City staff recommends that this area be shown as an outlot and be dedicated to the City to preserve the area adjacent to the "protect" wetland. Wetland Buffer Issue The attached memo from John Smyth discusses the need to mitigate the average buffer width that is lost due to Street B encroaching within the buffer strip. As the memo states, Protect wetlands allow no buffer averaging. Street B encroaches into the buffer and wetland area by 35 feet. The location of the roadway is constrained by the connection to Akin Road and the pond to the north. Based upon the "no buffer averaging" requirement, it is recommended that impacts to the buffer from the road be allowed if a buffer is re-established on the fill slope of the road and the average width of the entire buffer is equal to the minimum buffer width. Therefore, the fill slope area at 35 feet in width and 200 feet in length needs to be re-established with vegetation appropriate and consistent with the buffer strip. If site constraints prohibit achieving the average buffer width, the additional buffer area needed should be included elsewhere in the development. Landscaping As reported in the Environmental Assessment Worksheet (EA W), the Developer proposes to preserve approximately 40 percent of the forested area on the site. The forested area that will be affected due to grading of the site is the 24.3 acres located in the northeast portion of the site. As described in the EA W, American Elm and Bur Oak with understory of common buckthorn and prickly ash dominate this forested area. With the large amount of mass grading proposed on the site, the Developer proposes to replace many of the larger trees with oaks, maples, birch and lindens along the roadways. Additionally, the Developer proposes to landscape each villa, garden and garden townhome with a number of plantings as shown on the attached landscape plan. The Developer also proposes to re-establish a buffer area of trees along the shared property line with the five homes along Akin Road. However, City staff recommends that landscaping also be installed along the pond area that is adjacent to the Pettis property. Phasing of the Development The developer is proposing to gain preliminary plat approval for the entire development by the end of July 2000 with final plat approval for various phases of the development shortly thereafter. The developer will begin construction of the villas along the northern property and 6 . . . the gardens along the western property line in the first phase. The developer plans on the construction of model homes for marketing purposes and plans to be built-out within 3 to 5 years. Homebuyer & Housing Characteristics The development is proposed to meet the needs of the first time homebuyer, the move-up purchaser and the "empty nester" looking to down size. . The villa townhomes will accommodate the first time homebuyer and are the most affordable in the Rottlund Development. This product will range in size from 1,220 to 1,645 square feet. The villas will be part of the first phase of development on the property. The gardens and the garden townhomes will meet the needs of the "empty nester" with one level living in the gardens home and one level and a basement living in the garden townhomes. These products will range in size from 1,260 to 1,450 square feet. The gardens and garden townhomes will also be a part of the first phase of development on the property. The single-family product will accommodate the move-up segment of the population and will range in size from 1,850 to 2,700 square feet in rambler, split level and two-story configurations. The single-family construction will be included in later phases of the development; however, most of the utilities and streets will be installed in the first phase. Population Projections The developer has estimated that at total build-out the population of Vermillion Grove will be near 743 persons. These projections are based on the following: 148 villa townhouses @ 1.25 persons per unit (ppu) 135 garden and garden townhomes @ 1.8 ppu 97 single-family homes @ 3.25 ppu = 185 persons = 243 persons = 315 persons Summary of Requirements 1. Approval of the Vermillion Grove Preliminary Plat is contingent upon an agreement being reached between Pettis and Rottlund Homes for the purchase of a small piece of property owned by Pettis in order to connect with Akin Road to the east. 2. Approve a IS-foot variance from the maximum cul-de-sac length of 500 feet for the cul-de- sacs on Streets C, D, E and N. 3. Require a 66-foot right-of-way with a 50-foot radius to the face of curb for cul-de-sacs on Streets C, D E and N and Drive H. 4. Require Streets C, D, E and N to be reduced from 34-foot back to back roadways to 30-foot back to back roadways meeting the City's criteria for 28-foot wide streets thereby requiring a sidewalk on one side of the street. 5. Require a sidewalk on one side of Street B to promote pedestrian safety and provide a pedestrian access to Akin Elementary School to the north from these neighborhoods. 6. Require the driveways on the west side of buildings 62, 63, and 64 to meet the requirements of the City's Dead End Access Road Policy per Fire Code requirements (copy attached). 7. Require additional trees to be installed along the east side of the storm water pond adjacent to the Pettis property for screening of the development. 7 . . . 8. Require the re-establishment of the buffer area along the fill slope of Street B per requirements of the Wetland Ordinance and/or additional buffer area to achieve the average buffer width. 9. Approval of the Vermillion Grove Preliminary Plat is contingent upon all engineering requirements being addressed. ACTION REQUESTED Recommend approval of the Vermillion Grove Preliminary Plat contingent upon the above requirements and forward this recommendation to the City Council.

Ponds must be platted as outlots to the high water level. Access to ponds on outlots must . be included within the outlot. 3. The parkland areas need to be defined and platted as Outlots. Street Issues 1. All street designs must be in accordance with City standards. Cul-de-sacs are currently shown with a 47-foot radius to back of curb with a right-of-way radius of 60-feet. City standards require a 66-foot right-of-way radius and 50-foot radius to face of curb. 2. Street grades should be limited to a maximum of 7.0%. 3. Turn lane and bypass lane improvements will be required on Akin Road at the intersection with Street B. The intersection of Street A and 195th Street will need to be reviewed to determine if turn lanes are necessary. 4. Retaining walls must be placed outside of City easements on private property. Retaining walls that retain higher than four-feet must be designed by a structural engineer. 5. At a minimum, sidewalks or trails need to be provided along collector routes, including Street A and Street B. Utility Issues . 1.

Project Name: Vermillion Grove Response to EAW Comments Client: City Of Farmington File No: 141-99-114 To: Lee Smick Date: 6/6/00 From: John Smyth Re: Review of Vermillion Grove Response to Comments dated 6/14/00 Remarks: I have reviewed the Vermillion Grove responses to EA W comments in regards to Wetland Protection. One concern relates to response 3 of Peterson Environmental to the Dakota County Soil and Water Conservation District, EAW Item 12 - Wetland Buffers. The following statement is not entirely correct: "One of the stormwater treatment ponds will encroach into a wetland buffer, however, this has been accepted by the City of Farmington in the past because the pond serves the same purpose as the buffer that surrounds it." In my memo for Vermillion Grove PUD EA W dated February 14, 2000 under General Buffer Area Requirements it states that "It appeared that the current pond location along the fringes of the wetland may be within the vegetated portion of the buffer. Ifponding is to occur within the buffer it should be limited to the cropped area." . The first project that requested ponding in the buffer was Charleswood 3rd Addition. The ordinance language below is followed by the City's interpretation of the ordinance which was met by Charleswood 3rd Addition. Ordinance Language: The wetland ordinance discusses this issue under section 10-9-7 (E). Clearing and removal of vegetation in the buffer area is prohibited, except for selective clearing and pruning, of individual trees and shrubs which are dead, diseased, noxious weeds, or water hazards. This section is interpreted to indicate that grading within a buffer area that has existing natural vegetation would not be allowed. This interprtation is consistent with other City ordinances. City's Interpretation The following interpretation of the ordinance has been developed so that the criteria regarding allowing grading and ponding in a buffer area is consistent for each development. 1. Grading within buffer areas, including ponds, should be limited to areas that have had a history of being farmed. Farming within the buffer needs to have occured 7 out of 10 years to be considered having a history of being farmed. 2. If the ponding location meets the criteria above in item 1, then it can be counted as buffer area as long as the minimum vegetative buffer areafor the classification is maintained. In the case of Vermillion Grove, the minimum width for the buffer strip for a Protect Wetland is the same as the overall buffer width, so no part of the buffer strip can be used for ponding without a variance to the Farmington Wetland Ordinance. In other words, the buffer strip cannot be designed to an "average" width. The entire buffer strip must meet the minimum width. The plans currently show grading for a berm around the pond site extending into the buffer area. This grading needs to be eliminated from the buffer in order to be in compliance with the City Wetland Ordinance. . Another proposed encroachment into the required buffer occurs with the proposed road access to Akin Road. Roads are discussed under Section 10-9-7 (K) of the Farmington Wetland Ordinance. This section reads as follows: "For roadways, trails, and driveways, or portions thereof, that are routed across wetlands and are subject to WCA Bonestroo, Rosene, Anderlik and Associates 2335 West Highway 36 + St. Paul, MN 55113 + Phone: 651-636-4600 + Fax: 651-636-1311 n Bonestroo -=- Rosene "IilI Anderfik & 1\11 Assodates EngIneers & Architects . replacement requirements, no buffer areas shall be required." The purpose of this statement in the ordinance was to insure that an applicant would not widen a road embankment to meet buffer requirements and therefore impact more wetland area. Memo The proposed road does not impact wetland and thus it does not require a replacement plan and therefore the exemption for the buffer strip does not apply. However, the city does not want applicants routing roads through wetlands to meet the above exemption so impacts to buffer strips from roads will be allowed with the following conditions: 1. Impact to the buffer strip by roadways, trails or driveways should be minimized to the extent possible while still providing public saftey and access to development. 2. After minimizing the impact of the road to the buffer strip, the embankment of the road should be re-established with vegetation appropriate and consistent with the buffer strip. 3. Road impacts to buffer strips will be allowed ifItems I and 2 above are followed and the overall buffer strip average for the wetland classification is maintained. This would include Protect wetlands in which buffer strip averaging is not typically allowed. . The location of the road is constrained by the existing connection at Akin Road and the required ponding for the development. Based on the discussion above, it is recommended that the impacts to the buffer from the road be allowed if a buffer is re-established on the fill slope of the road and the average width of the entire buffer is equal to the minimum buffer width. The fill slope extends along 200 feet of the wetland buffer and is approximately 35 feet wide. This area should be re-established into a buffer in accordance with Section 10-9-7(C) of the Wetland Ordinance. This would provide 35 feet of buffer strip that would be included in calculating the average buffer width. The remaining buffer strip should completed elsewhere on-site to meet the overall buffer average of 75 feet. If site constraints prohibit achieving the average buffer width, the additional buffer area needed should be included elsewhere in the development.

"- Dear Lee: The Dakota County Soil and Water Conservation District (SWCD) has reviewed the Preliminary Grading Plan for the above-mentioned site. This project entails 145 mixed use lots on approximately 122 acres. The following report summarizes the proposed erosion controls, submits additional erosion control recommendations, and discusses alternative site design considerations to minimize development impacts. Erosion Control Observations . "1. Silt fence at the downslope gradients and around wetland areas. 2. Multiple storm water ponds. Erosion and Sedimentation Control Comments and Recommendations 1. Project phasing is critical to minimize erosion and sedimentation on this site. Show how the site will be phased and exposed soils will be kept to a minimum. 2. Develop a phased grading plan to show how drainage on the site will be controlled during active grading. 3. All slopes exposed adjacent or directly tributary to the DNR wetland should be brought to final grade and stabilized immediately. 4. Construct the stormwater ponds first to use as temporary sediment basins. Install a floating riser or similar structure to enhance sediment trapping efficiency. The pond should be stabilized immediately and a controlled overflow structure installed. 5. Install a double row of heavy duty silt fence to protect the DNR wetland. Place the fence outside of the proposed buffer and have the fences about 6-10 feet apart. 6. Any areas adjacent or directly tributary to the DNR wetland that left idle for more than 7 days should have seed and temporary cover applied. This is a requirement of the NPDES permit. 7. Stabilize all 3:1 and steeper slopes with erosion blanket or hydromulch with tackifier. Show the location of these areas on the plan. Reguire that once these areas are exposed, they are finish graded and stabilized promptly. 8. Install all silt fence on-contour. Cross-contour silt fence tends to concentrate runoff and cause silt fence failures. 9. Show the location and type of energy dissipation devices at all storm sewer outfalls. 10. Show the location and type of check dams in areas of concentrated flow. 11. Show the location of the rock construction entrance. .

Include locations and specification of all erosion controls on the plan. 14. Additional controls may be deemed necessary during construction to protect the DNR wetland. Further, there are many opportunities on the site to install diffuse integrated management practices (IMPs) to retain water on the site and mitigate long term, down stream erosion and water quality issues. The Dakota SWCD has cost-share funds available to design and install these low impact development (LID) practices. Thank you for the opportunity to review this plan. Because the sites will disturb more than five acres, a National Pollutant Discharge Elimination System (NPDES) General Sfurmwater Permit is required. Good implementation, consistent monitoring, and maintenance of all erosion control measures are important to minimize erosion on this construction site.

April 28, 2000 ~~8U:]~~ Mr. Dave Olson, Community Development Director, City of Farmington, 325 Oak Street, Farmington, MN 55024 Dear Mr. Olson, RE: Application for Preliminary Plat Approval Vermillion Grove . We are pleased to submit for the City's consideration our application for preliminary plat approval for the proposed Vermillion Grove community. This plan, I believe, represents the culmination of considerable effort on the part of many parties and individuals. We truly appreciate the interest and assistance provided by staff in the Engineering, Community Development/Planning, Parks and Finance Departments. The advice and feedback that has been provided over the past number of months has been invaluable in terms of refining our preliminary plat. Enclosed you will find the City's standard application form executed by the Rottlund on behalf ofthe owner ofthe property, our checks to cover the City's application and escrow requirements, 15 copies of the preliminary plat and associated information, a reduced copy of the plat, hydrology report and abstractor's certification. In addition, our consulting engineer, Pioneer Engineering, has provided a cd on which all plans are contained in an electronic format. We trust this provides the City will all information its requires to process our application and move it forward for consideration by the City's Planning Commission and Council. As we have discussed previously we are targeting a hearing before the City's Planning Commission and Council on June 13,2000 and June 19,2000, respectively. Should you require any additional information or clarification please do not hesitate to contact the undersigned. Special considerations being requested by Rottlund are summarized under the heading "pud requirements" on the cover sheet to the pud plan package. These requirements touch upon such things as private and public street widths (pavement and right of way), minimum lot setbacks and setbacks from county roads, designated wetlands and the gas .

One requirement that this not enumerated on this sheet is for special . consideration for a relaxing of the maximum cui de sac length requirement. . . Further, we are also requesting the ability to construct model homes prior to the first lift of asphalt. This is a commonly accepted practice throughout other municipalities in the metropolitan area. We would appreciate the opportunity to discuss with the City an acceptable milestone for the receipt of permissions to construct models and models alone. For the information of the City, the single family lots proposed for this development have an average lot width of70 feet and average lot depth of 130 feet. Lots of these dimensions, we feel, are able to meet the demands of the consumer and allow for the construction of a variety of homes. We would respectfully request that the City undertake a comprehensive and total review of our submission, rather than the raising of possible issues as they emerge. This approach allows all parties to deal with the Vermillion Grove development in a total versus an incremental manner, thereby allowing all issues to be considered at one time and in a way where interrelationships and connections are fully understood. We believe that whatever issues do emerge they can be addressed through an appropriately worded condition of approval governing the preliminary plat. Rottlund is confident that this approach would enable the approval process to move forward, while at the same time providing the necessary protection and assurances to the City. We appreciate the City prompt and professional consideration. Weare at your convenience in terms of meeting to discuss our application or providing the City any additional information.
