Adjourn City of Lake Elmo Planning Commission Meeting Minutes of July 14, 2014 Chairman Williams called to order the meeting of the Lake Elmo Planning Commission at 7:00 p.m. COMMISSIONERS PRESENT: Williams, Dodson, Kreimer, and Lundgren. COMMISSIONERS ABSENT: Larson, Haggard and Dorschner. STAFF PRESENT: Community Development Director Klatt and City Planner Johnson. Approve Agenda: The agenda was accepted as presented. Approve Minutes: June 30, 2014 M/S/P: Lundgren/Dodson, move to approve the minutes as amended, Vote: 4-0, motion carried, with Kreimer not voting. Public Hearing: Kwik Trip – Preliminary Plat, Final Plat and Conditional Use Permit Johnson presented an overview of a proposed conditional use permit to allow the construction of a new Kwik Trip gasoline station/convenience store at the intersection of I-94 and Keats Avenue. He stated that staff is recommending approval of the conditional use permit with the conditions of approval as listed in the staff report. Johnson reviewed draft findings with the Planning Commission to support this recommendation, and asked if the Commission had any questions concerning the proposal. Dodson asked if a lower speed limit would have any implications for the proposed turn lanes. Johnson replied that as traffic builds along Hudson Boulevard and additional development occurs that there would likely be a reduced speed limit along this road. Johnson indicated that this would not occur until sometime in the future. The Commission asked general questions concerning the layout of the proposed driveways and approaches into the site. Bruce Miller, MFC Properties, noted that he was the owner of the property and that he has been working with the City to address the review comments. He stated that he is looking to develop the adjacent parcel to the North, and that this project would be a good first project to get things going in the I-94 Corridor. Lake Elmo Planning Commission Minutes; 7-14-14 2 Scott Tigen, Chief Financial Officer for Kwik Trip, discussed the approach used by Kwik Trip in designing and siting its stores. He reviewed some of the history of the organization and the philosophy of its owners. He noted that the second access drive is critical to maintain safety on the site, and in particular to minimize the amount of backing up done by larger trucks on the site. Williams questioned the location of the proposed trees in front of the car wash signage, and expressed concern that these would need to be removed in the future. Tigen stated that the trees would take preference to the signage, but that he did not think there was going to be a conflict. Public Hearing opened at 7:46pm. Public Hearing closed at 7:47pm. Kreimer asked if there were any concerns with the sign plan as submitted. Johnson replied that the applicant would need to submit a sign permit, at which time Staff would perform a thorough review of the proposed sign for consistency with the Sign Ordinance. M/S/P: Lundgren/Dodson, move to recommend approval of the Preliminary Plat , Final Plat and Conditional Use Permit of Kwik Trip with the 8 conditions recommended by Staff based on the findings of fact listed in the Staff Report as amended by the Planning Commission, Vote: 4-0, motion carried unanimously. Public Hearing: Comprehensive Plan Amendment – Eliminate RAD-ALT Land Use Category. Klatt noted that the Planning Commission reviewed this item in the past. The proposed action is being brought before the Planning Commission again in response to the finalized 2040 population forecast by the Metropolitan Council. Klatt noted that a large amount of information has been presented in the past regarding the RAD-Alt properties. Klatt identified where the parcels guided RAD-Alt in the City’s Comprehensive Plan are located. Klatt explained the purpose behind the inclusion of the original RAD-Alt category. He provided background information related to the 2040 Met Council population forecast for Lake Elmo. Klatt identified and described the three parcels that are guided RAD-Alt. Moving on to the Staff Recommendation, Klatt noted that staff is recommending that the RAD-Alt category be eliminated from the Comprehensive Plan. Klatt then highlighted the proposed findings of fact, stating that some of the findings take into account previous Planning commission and City Council discussion of the proposed action. Lake Elmo Planning Commission Minutes; 7-14-14 3 Kreimer asked if there has been any RAD-Alt development in the community. Klatt noted that there has not been any RAD-Alt development. Dodson asked if RAD-Alt development is possible when not served by public sanitary sewer. He does not see the densities associated with RAD-Alt possible without sewer. Klatt noted that it would be very difficult to serve these sites at these densities with private sanitary systems. Public Hearing opened at 8:22 pm. Williams noted that Janice Greene submitted a letter for the Friedrich family noting their objection to the elimination of RAD-Alt. The letter was entered into the public record. Larry Weiss, 9302 Stillwater Blvd. N., noted that the Friedrich site was changed to RAD- Alt for a specific project and the project has not been built. He noted that he is not supportive of RAD-Alt densities in the rural areas. He stated that the neighborhoods surrounding these sites do not want development at the density associated with RAD – Alt. Terry Emerson, 2204 Legion Ln. N., stated that he does not oppose eliminating RAD-Alt, but would like to develop his parcel as single family OP neighborhood, but would like to consider some variances. Ed Nielsen, 9499 Stillwater Blvd., stated that he would like to see the RAD-Alt go away because it equates to spot zoning. Public Hearing closed at 8:29 pm. Williams stated he would like to add a finding that the 2040 population projections can be reached without inclusion of the RAD-Alt land use category. Kreimer noted that he is conflicted because the reduction of the overall population forecast is not that large. He noted that if there are allowances for population relief, the Village and South of 10th should be considered for land use changes. Dodson noted that he is concerned with being able to pay for the public infrastructure investments that have been made in the sewered areas. He does not support reductions in those areas until the City is sure they can finance these public infrastructure improvements. Williams agreed with Dodson. M/S/P: Dodson/Lundgren, move to recommend approval of the Comprehensive Plan Amendment to Eliminate RAD-Alt (Rural Area Development Alternative Density) as a land use category from the Future Land Use Map as referenced in the Comprehensive Lake Elmo Planning Commission Minutes; 7-14-14 4 Plan subject to the condition of approval recommended by staff and based upon the findings of fact listed in the Staff Report as amended by the Planning Commission, Vote: 3-1, motion carried with Kreimer voting no. Public Hearing: Zoning Map Amendment – Perfecting Amendments Klatt started his presentation of the Zoning Map Amendment – Perfecting Amendments to change to the zoning for several properties guided for pending development as well as other clean-up perfecting amendments. He presented an overview of the subject properties one by one. Public Hearing opened at 8:50pm. Williams noted that a letter was submitted by Steve Delapp. It was entered into the public record. Public Hearing closed at 8:52pm. M/S/P: Williams/Dodson, move to recommend approval of the Zoning Map Amendments as presented in the Staff Report. Vote: 4-0, motion carried unanimously. Updates and Concerns Council Updates 1. Hammes Shoreland Variance was withdrawn by the applicant 2. Hunter’s Crossing Preliminary Plat passed with 15 conditions of approval 3. Eagle Point Medical Center Preliminary and Final Development Plans passed with 7 conditions of approval 4. Hammes Estates Preliminary Plat passed with 17 conditions of approval. Staff Updates 1. Upcoming Meetings a. July 28, 2014 b. August 11, 2014 – Lundgren will be unable to attend. Commission Concerns - Lundgren noted that the Planning Commission should have identification for visiting development sites. Lake Elmo Planning Commission Minutes; 7-14-14 5 Williams noted that he is concerned about crowding of some of the Lennar developments that he has observed recently. Dodson agreed but doesn’t know what the solution could be. Meeting adjourned at 9:01pm Respectfully submitted, Joan Ziertman Planning Program Assistant Lake Elmo Planning Commission Minutes; 7-14-14 PLANNING COMMISSION DATE: 7/28/14 AGENDA ITEM: 4A – PUBLIC HEARING CASE # 2014-30 ITEM: Boulder Ponds – Preliminary Plat and Preliminary PUD Plan SUBMITTED BY: Nick Johnson, City Planner Kyle Klatt, Community Development Director REVIEWED BY: Jack Griffin, City Engineer South Washington Watershed District Greg Malmquist, Fire Chief Stephen Mastey, Landscape Architecture, Inc. SUMMARY AND ACTION REQUESTED: The Planning Commission is being asked to consider a Preliminary Plat and Preliminary PUD Plan application from OP3 Boulder Ponds, LLC for a 162-unit planned residential development to be located on 58.3 acres of land within Stage 1 of the City’s I-94 Corridor Planning Area. The proposed residential project is located immediately north of Hudson Blvd. N., immediately east of the Eagle Point Business Park and immediately south of the Stonegate residential estates (RE) subdivision.

Comprehensive Plan: Urban Low Density Residential (2.5 – 3.99 units per acre), Urban Medium Density Residential (4.0 – 7.49 units per acre) and Commercial History: Boulder Ponds General Concept Plan review by Planning Commission on 12/9/13 and approved by the City Council on 12/17/13. Deadline for Action: Application Complete – 6/19/2014 60 Day Deadline – 8/17/14 Extension Letter Mailed – No 120 Day Deadline – 10/16/14 Applicable Regulations: Chapter 153 – Subdivision Regulations Article 10 – Urban Residential Districts (LDR and MDR) Article 16 – Planned Unit Development Regulations §150.270 Storm Water, Erosion, and Sediment REQUEST DETAILS The City of Lake Elmo has received a request from OP3 Boulder Ponds, LLC for a Preliminary Plat and Preliminary PUD Plan to subdivide approximately 58 acres of land located within Stage 1 of the I-94 Corridor Planning Area into 98 detached residential lots. The proposed plat would be located on property primarily owned by the Louis Damiani Revocable Trust (represented by William Kuhlmann) and Timothy Montgomery, and would be located immediately north of Hudson Boulevard, immediately east of Eagle Point Business Park, and immediately south of the Stonegate subdivision. The 78 acre parcel has historically been used for agricultural purposes. The preliminary plat has been developed in response to the City’s Comprehensive Plan, which identifies the applicant’s property for urban low density residential, urban medium density residential and commercial. The proposed planned development includes 98 detached residential lots, located both north and south of the City’s planned 5th Street minor collector road. In addition to the proposed detached residential lots, the plat includes an outlot (Outlot K) planned for a 64-unit senior housing facility or apartment. While approval is not being sought at this time, it is worth noting that the proposed senior housing is consistent with the approved General PUD Concept Plan approved by the City in December of 2013. In terms of access, the preliminary plat and PUD plan shows a north-south connection to Hudson Boulevard in the southern portion of the plat. In addition to the Hudson Blvd. connection, the proposed plat includes a significant portion of the 5th Street minor collector road. As part of the total public improvements of the Boulder Ponds planned development, the 5th Street minor collector road will be constructed from the Savona (Lennar) urban low density subdivision in the east to the PUBLIC HEARING ITEM 4A – ACTION ITEM 3 approximately 160-acre parcel owned by Azure Properties to the northwest. Along with the connection to Hudson Blvd., the 5th Street minor collector road will ultimately serve as the primary access to the Boulder Ponds development. The Boulder Ponds planned development is the City’s third proposed subdivision in Stage 1 of the I- 94 Corridor Planning Area that will receive public sanitary sewer service, which has been made available to the site via the completed Section 34 Public Utility Project. At present, the water for this area is provided by the City of Oakdale. However, the City plans to execute a trunk watermain extension down Inwood Avenue (CSAH 13) in the next year or two to connect existing facilities in the western I-94 Corridor to the City water system. At present, there is enough capacity in the Oakdale system to provide water to a significant portion of Stage 1 of the I-94 Corridor Planning Area until Lake Elmo makes the needed connections to its system. Sewer and water for the Boulder Ponds site is accessible along Hudson Blvd. as a result of the Section 34 Utility Project. The applicants are proposing to extend sewer and water throughout their site from the facilities located in Hudson Boulevard. One of the other major features of the proposed subdivision is a continuation of the northern buffer greenbelt along the northern boundary of the site adjacent to the Stonegate subdivision. The greenbelt is required under the guidance of the City’s Comprehensive Plan. As proposed, the greenbelt includes a trail segment from the proposed Savona single family development in the east across the northern boundary of the site to Stonegate Park in the west. In addition to connection to Stonegate Park, the northern buffer trail as proposed also provides connection to the City’s planned minor collector road, 5th Street. It should also be noted that a significant portion of the greenbelt buffer area includes a Northern States Power (Xcel Energy) easement for overhead utilities. As currently proposed, the single family or detached residential portion of the Boulder Ponds development will be constructed in two phases. The initial phase of the project includes construction of the access road to Hudson Blvd., as well as the eastern portion of the 5th Street minor collector road. In addition, Phase I as proposed includes 47 residential lots, both of the traditional single family and “Villa” type. The second phase of the residential development includes the construction of the remaining residential lots and local roads, as well as the western portion of the 5th Street minor collector road. Finally, it should be noted that the Boulder Ponds development is proceeding through the Planned Unit Development (PUD) process. By proceeding through the PUD process, the City may allow for flexibility in the use of land or the base standards of the zoning code with the intent of achieving higher quality development. The City’s PUD process has three phases: 1) General Concept Plan, 2) Preliminary Plan, and 3) Final Plan. It should be noted that the City reviewed the Boulder Ponds General Concept Plan (12/9/13 - Planning Commission, 12/17/13 – City Council), which was approved by the City Council (Resolution #2013-109). Approval of the General Concept Plan allows the applicant to proceed with preparation of preliminary plans, which the applicant has now submitted. Staff has reviewed the approved General Concept Plan and all the conditions associated with the approval. The most critical conditions, relating to the alignment of the 5th Street minor collector road, have been resolved by the applicant. In addition to the issues related to the alignment of 5th Street, the submitted preliminary plat and preliminary PUD plans have generally addressed the other conditions of approval related to the review of the General Concept Plan. It should also be noted that the Boulder Ponds preliminary plat and preliminary PUD plan does contain 5 additional residential lots than the General Concept Plan. The additional lots created in the subdivision directly relate to a change in product type, as the applicants are proposing “Villa” homes, a detached townhome on HOA maintained land. Staff reviewed the proposed increase and units and found it to be consistent with the general intent of the approved General Concept Plan. The minimal number of PUBLIC HEARING ITEM 4A – ACTION ITEM 4 increased lots are being accommodated within the same street and utility network, not leading to significant changes to the proposed public improvements. PLANNING AND ZONING ISSUES The Boulder Ponds site is guided for urban low density, urban medium density and commercial development in the City’s Comprehensive Plan, and the applicant will be required to zone the site to the appropriate zoning designation as part of Final PUD Plan approval. The overall subdivision plan has therefore been prepared in order to generally comply with the district standards for the LDR and MDR zoning districts. However, as part of the request for a planned development, the applicant is permitted to request reductions in lot size, building setbacks, and other requirements of the base zoning district. Therefore, it should be noted that four of the proposed lots (Lots 4, 7, 8 and 10, Block 3, 2nd Addition) are slightly under the minimum requirements for lot size. In addition, the applicants are requesting reduced side-yard and front-yard setbacks. These requests were established at the General Concept Plan phase of the PUD process and were supported through the approval of the General Concept Plan. In terms of the general design of the subdivision, the northern and southern portions are split between the City’s planned minor collector road, 5th Street. The southern portion is accessed off the north- south access road, called Cobblestone Plaza, connecting to Hudson Blvd. and contains 20 proposed “Villa” units, which is a detached single family product with HOA maintained grounds. In addition, according to the General Concept Plan, the southern portion of the planned development will also include a 64-unit senior living multi-family building to be located on Outlot K at some point in the future. The proposed senior living building is not currently included in the present application. The design of the northern portion of the subdivision primarily follows one through street, Boulder Ponds Parkway, which connects to the planned 5th Street in both the central and northwestern areas of the plat. In addition to the main through street, three cul-de-sacs are proposed off of Boulder Ponds Pkwy. The northern portion of the proposed subdivision is comprised of all single family residential land uses, with 60 traditional single family homes and 18 Villa units. The proposed design of the subdivision does allow for a significant amount of open space, allowing all the residential lots to back up to some form of open space as opposed to additional lots. In addition, the overall design (streets, sidewalks, building pads, etc.) is intended to provide a curvilinear aesthetic and pattern. Along with varied setbacks and meandering sidewalks, the applicant has noted that creating visual interest within the development is a critical component to the overall vision. Sidewalks and trails are planned throughout the subdivision. The proposed plans provide for sidewalks on one side of all streets, which is consistent with the Staff recommendation for sewered single family residential subdivisions. In terms of proposed trails, all are designed to be ten feet in width and constructed of bituminous asphalt, which is consistent with the City standard for a regional trail. In addition to the buffer/greenway trail, the proposed subdivision includes a linking trail segment to the northeastern cul-de-sac, Pebblestone Ridge Cove. Finally, the proposed minor collector road 5th Street includes a regional trail on the north side of the road, which is consistent with the City’s typical section. The Boulder Ponds subdivision includes two general types of residential lots: traditional single family and Villa. As proposed, there are 60 traditional single family lots. The average size of the traditional single family lots is 9,735 square feet. In addition, the largest traditional lot (Lot 1, Block 2, 1st Addition) is 15,832 sq. ft., while the smallest proposed traditional lot (Lot 8, Block 3, 1st PUBLIC HEARING ITEM 4A – ACTION ITEM 5 Addition) is 7,206 sq. ft. in size. Regarding the Villa lots, this lot type is intended to serve a different residential product than the traditional single family lots, allowing for a detached townhome type product. According to the applicant narrative, the Villa lots are intended to serve an empty-nester demographic, and the grounds of the Villa lots would be HOA maintained. As proposed, the Boulder Ponds subdivision includes 38 Villa lots, which are located within Block 1, 1st Addition and Block 1, 2nd Addition. The average size of the Villa lots is 10,116 square feet. The largest Villa lot is 18,906 sq. ft., while the smallest Villa lot is 7,347 sq. ft. in size. It should be noted that the lot sizes of the traditional single family and Villa homes are comparable in size. The main differences between the lot types are the product type (single family home vs. detached townhome) and maintenance (owner maintained vs. HOA maintained). In order facilitate the review of the proposed lots and lot types, the applicants have submitted an updated lot summary that identifies the lot type (single family vs. Villa). The updated lot summary is found in Attachment #3. The following is a general summary of the subdivision design elements that have proposed as part of the Boulder Ponds preliminary plat and plans: Zoning and Site Information: • Existing Zoning: RT – Rural Development Transitional District • Proposed Zoning: LDR, MDR and C • Total Site Area: 58.3 acres • Total Residential Units: 98 • Proposed Density (Net): Northern - 2.69 units/acre, Southern – 8.05 units/acre* (*Note: includes future planned 64-unit senior living multi family building) Proposed Lot Dimensional Standards through Planned Unit Development Process: • Lot Area: 9,882 sq. ft. average (7,206 sq. ft. min.) • Front Yard Setback: 20 ft. (25 feet for garage) • Side Yard Setback: 5 ft. • Rear Yard Setback: 25 ft. Proposed Street Standards: • ROW Width – Local 60 ft. (per Subdivision Ordinance) • Street Widths – Local: 28 ft.(per City standard) The standards listed above are all either in compliance with the applicable requirements from the City’s zoning and subdivision regulations, or are consistent with requested modifications through the proposed planned unit development (PUD). Based on Staff’s review of the Preliminary Plat and Preliminary PUD Plan, the applicant has generally demonstrated compliance with the majority of the applicable codes, and the requested modifications or flexibilities as allowed under the City’s PUD Ordinance represent a reasonable request given the various design goals the applicant it trying to achieve. The applicant is requesting some additional flexibility through the PUD process to receive advance approval for an alternate design for certain portions of the development. The proposed alternative designs are detailed in the attached document titled “Boulder Ponds – Alternative Site Plan” (Attachment #8) and detailed on the site plans labeled Exhibit “A, B and C” – Alternative Single Family Detached Townhouses. As specified in these plans, the applicant has asked for flexibility to build houses consistent with the proposed preliminary plat, or to change the housing type for certain PUBLIC HEARING ITEM 4A – ACTION ITEM 6 portions of the development to a single-family detached townhouse-type building, or Villa, on smaller lots. There are three specific portions of the development that are identified for this alternative layout, and in total, the proposed flexibility would add nine additional lots to the plat beyond the base conditions. The addition of these lots would not increase the net density for any portion of the project so that it exceeds the underlying density in the Comprehensive Plan. Because the requested alternative plans would not alter the layout of any proposed streets or significantly alter the grading and utility plans for the site, Staff is recommending that the preliminary PUD plans be structured in a way that allows the applicant to move forward with either option. Please note that should the developer move forward with one of these alternatives, the preliminary plans will need to be updated in their entirety to reflect the updated plans. Under such a scenario, the developer would be able to submit revised preliminary plan simultaneously with a final PUD and final plat. The comments from Staff included in the latter portions of this report address the plat as submitted; any future plans that incorporate the alternative plans would be subject to a complete plan review. As with any new subdivision, the City Code requires that a portion of the plat be set aside for public park use. In this case, the applicant has indicated that the northern outlot area, labeled Park, will be dedicated to the City for this purpose. The City’s Subdivision Ordinance requires 10% of the land in urban residential districts to be set aside as parkland, which according to the applicant’s calculation would represent 4.09 acres of land. On the submitted narrative for the Boulder Ponds project (Item D), the applicant has noted that 3.85 acres of land within or adjacent to the greenbelt/buffer have been dedicated as park. However, City staff is unclear if this calculation includes the area within the Xcel Energy easement, which would not be eligible to be counted towards the required parkland amount. Related to this requirement, the Subdivision Ordinance states the following: (C) Land acceptability. The city must approve the location and configuration of any park land which is proposed for dedication and shall take into consideration the suitability of the land and for its intended purpose; the future needs of the city for parks, playgrounds, trails, or open space; and the recommendations of the city’s Parks Commission. The following properties shall not be accepted for park land dedications: (1) Land dedicated or obtained as easements for streets, sewer, electrical, gas, storm water drainage and retention areas, or other similar utilities and improvements; Given that a significant portion (approximately 75 feet x 1300 feet) of the land proposed to be dedicated is subject to a Xcel Energy overhead utility easement, the portion of the parkland within the easement would not be eligible for parkland dedication credit. In addition to the eligibility the land provided, it should also be noted that the applicant has removed the area of the 5th Street right-of-way and the area of the required northern greenbelt buffer from the land calculation for parkland. While staff agrees that the right-of-way for the 5th St. minor collector road should not be included in this calculation, the northern greenbelt is considered part of the gross area being subdivided for development. For this reason, the greenbelt area, 2.83 acres according to the applicant’s narrative, should be included in the gross land calculation in determining the amount of required parkland dedication. Inclusion of the greenbelt area in the total land calculation for parkland dedication would be consistent with other subdivisions (Savona and Hammes Estates) that have incorporated portions of the greenbelt buffer around the Stonegate subdivision. In order to address the issues related to the correct level of parkland dedication, Staff would recommend that as a condition of approval (Condition #2) the applicant submit an updated parkland dedication calculation in advance of Final Plat. Upon review of the updated calculation, if any gap PUBLIC HEARING ITEM 4A – ACTION ITEM 7 exists between the eligible land dedication provided and the required land dedication amount, the applicant will be required to submit a fee in lieu of land dedication to satisfy the total land dedication requirement (10%) per the Subdivision Ordinance. It should also be noted that in the submitted narrative, the applicant has requested that the City consider some parkland credit for the construction of park related improvements that do not receive credit for land dedication. Staff would support that some credit be considered, as a significant stretch of trail is proposed over land that is not eligible for parkland dedication credit due to the overhead utility easement. Staff will continue to work with the applicant on how to properly achieve the required parkland dedication amount, whether it be through land, improvements, or fees in lieu of land dedication. REVIEW AND ANALYSIS City Staff has reviewed the Boulder Ponds preliminary plat and preliminary PUD plan. In general, the proposed plat will meet all applicable City requirements for conditional approval, and any deficiencies or additional modifications that are needed are noted as part of the review record. In addition, the City has received a detailed list of comments from the City Engineer, the Fire Chief and the City’s Landscape Consultant, Stephen Mastey, all of which are attached for consideration by the Commission. In addition to the general comments that have been provided in the preceding sections of this report, Staff would like the Planning Commission to consider the following review comments as well: • Comprehensive Plan. The proposed subdivision is consistent with the Lake Elmo Comprehensive Plan and Future Land Use Map for this area. The net densities for the development generally comply with the range allowed for the Urban Low Density and Urban Medium Density land use categories. In addition, other aspects of the Comprehensive Plan that relate to the Boulder Ponds subdivision are as follows: o Density Calculation. The subject property is guided Urban Low Density Residential, Urban Medium Density Residential and Commercial in the Comprehensive Plan. In order to demonstrate compliance with the City’s Comprehensive Plan with regards to proposed density, the applicant has submitted two density exhibits in the project narrative. The exhibits demonstrate that the overall number of proposed residential units fall well within the amount of planned growth under the Comprehensive Plan. While the net density calculation of the medium density area, 8.05 units/acre, is technically higher that the allowed range for MDR (4.0-7.49 units/acre), the overall planned growth for the area was greatly reduced by the realignment of the 5th Street minor collector road to the south, increasing the amount of land planned for Urban Low Density Residential. In addition, the density of the proposed project was reviewed along with the General Concept Plan. In reviewing the General Concept Plan, the City found that the proposed subdivision was consistent with the City’s Comprehensive Plan. With the addition of 5 residential lots since the approval of the General Concept Plan, the proposed subdivision remains in conformance with the planned growth as guided by the Comprehensive Plan. o Parks. The City’s park plan identifies proposed location for neighborhood parks based on the anticipated population that should be served by each park. The Park Plan does not call for additional parks in the vicinity of the Boulder Ponds subdivision, as it is located immediately adjacent to Stonegate Park. However, as part of the required greenbelt buffer, the land dedicated to the City as parkland will PUBLIC HEARING ITEM 4A – ACTION ITEM 8 include areas adjacent to Stonegate Park. This should allow opportunities to integrate trail and other facilities into Stonegate Park. However, any improvements will need to conform to the conditions of the Xcel Energy power line easement. o Water. Water will be provided to this area via existing watermain along Hudson Boulevard. The Boulder Ponds subdivision will be able to be served under the City’s current agreement with the City of Oakdale until the Inwood Ave. watermain extension project is completed. Staff anticipate that this project will be completed next year (2015). o Sanitary Sewer. The Boulder Ponds subdivision will be served by sanitary sewer that will connect to trunk gravity sewer in the Hudson Boulevard right-of-way. All of the wastewater will flow to the W.O.N.E. MCES regional wastewater interceptor. o Phasing. The Boulder Ponds subdivision is located within Stage 1 of the I-94 Corridor Planning Area. The proposed subdivision is consistent with the City’s Staging Plan, as the proposed development has access to both public sanitary sewer and water. • Zoning. The applicant has submitted an application for a Planned Unit Development, and has previously received approval of the General Concept Plan for Boulder Ponds. Consistent with the City’s PUD Ordinance, preliminary PUD plans have been submitted along with the preliminary plat. The final step in this process is submission of final PUD plans with a final plat. The underlying zoning for the PUD still needs to be established, and staff is recommending that the zoning be addressed at the final plan stage. In this case, the Comprehensive Plan guides the applicant’s site for several different land use categories, including low density residential, medium density residential, and commercial. Staff will be recommending that the zoning for the subdivision be established to match the Comprehensive Plan in the following manner: o LDR - All portions of the subdivision north (and east) of 5th Street. o MDR – All lots on Cobblestone Path and Outlots N and K. o C – Outlots J, M, and L At the time a final development plan is submitted, the official zoning map will be updated to reflect both the underlying zoning as noted above and will include a special designation marking the project area as a Planned Unit Development. • Planned Unit Development. The applicant has applied for a PUD, and therefore is seeking to take advantage of the flexibility allowed with this type of application. The specific aspects of the project that will be permitted through the PUD ordinance include the following: o Exceptions to the City’s minimum lot size requirements for LDR zoning to allow certain lots to be platted with less than the minimum of 8,000 square feet of area required in this zoning district. o Exceptions to the City’s setback requirements in LDR and MDR zoning districts to establish a minimum front yard setback of 20 feet (25 feet for garage) and side yard setback of 5 feet for all residential lots in the subdivision. o Exceptions to the City’s development standards for garages in urban residential zoning districts. The applicant has stated that a small number of the standard residential lots and a larger number of the proposed “Villa” homes will not be able to PUBLIC HEARING ITEM 4A – ACTION ITEM 9 meet the City’s 60% requirement concerning the width of garages on these site. Given the unique aspects of the “coving” subdivision design concept, Staff is recommending that the PUD plans be structured to eliminate this requirement in its entirety. o The ability to mix different types of uses as part of a larger development proposal that is connected as one development. The project will include single family detached homes, multi-family units, and commercial buildings, and has been designed to function as one unified development. o The applicant is proposing to meander sidewalks throughout the development both inside and outside of the street right-of-way. The City’s right-of-way standards depict sidewalks within a specific portion of the right-of-way. o Certain connecting trails are depicted within 20-foot easements; Staff has been asking that trails be dedicated to the City on Outlots of no less than 30 feet in width. o The proposed roads include several medians and landscape islands that are not otherwise included in the City’s street specifications. • Subdivision Requirements. The City’s Subdivision Ordinance includes a fairly lengthy list of standards that must be met by all new subdivisions, and include requirements for blocks, lots, easements, erosion and sediment control, drainage systems, monuments, sanitary sewer and water facilities, streets, and other aspects of the plans. Many of these requirements have been addressed as part of the City Engineer’s review memo (which is summarized below). After reviewing the proposed plat and PUD plan, Staff has not found any aspect of the plat that conflict with these requirements. • Infrastructure. The developer will be required to construct all streets, sewer, water, storm water ponds, and other infrastructure necessary to serve the development, including all portions of 5th Street that cut through the development. Also, Staff has reviewed the proposed phasing of construction for the public improvements and finds it to be acceptable. • Wetlands. The applicants have prepared a wetland delineation for the site, which identifies an existing wetland on Outlot O. The applicant is proposing to incorporate this wetland as part of the storm water management plan for the site, and will therefore need to comply with all applicable requirements of the Wetland Conservation Act for this work. The South Washington Watershed District is the responsible government unit for determining such compliance issues. • Trails. The developer is proposing to build a series of trails as part of the development, including a 10-foot bituminous trail along the northern portion of the subdivision through the required 100-foot open space buffer and a similar trail within the 5th Street right-of-way. The applicant is seeking park land dedication credit for all of the land within the open space buffer area and other adjacent portions of the site that are used for general open space or storm water facilities. Given the circumstances associated with the northern portion of the site, Staff is not recommending that the City accept all of the land shown as park along the northern boundary of the plat for the following reasons: 1) this portion of the site lies under a 75-foot power line easement and nearly all portions of the trail are located within this easement, 2) the area shown as park includes storm water ponding area, and 3) the Subdivision ordinance specifically prohibits using areas under a power line easement and within a storm water pond for park dedication requirements. PUBLIC HEARING ITEM 4A – ACTION ITEM 10 Because the trail does serve a public purpose, and because the City has previously allowed the buffer area to be used for park dedication purposes with the construction of a trail, Staff is recommending that the developer received credit for park land dedication as follows: o The equivalent land dedication equal to a 30-foot trail segment under all portions of the power line easement. o Land that is deeded to the City surrounding trails and located outside of the power line easement and storm water facilities. o Land within the 100-foot buffer in the northern portion of the site that is located outside of the power line easement and outside of storm water facilities. As noted earlier in this report, the exact calculations for park land dedications should be completed as part of the final plat submissions (Condition #2). Finally, although the northern greenbelt buffer trail is depicted as a 10-foot trail, Staff is recommending that the design of this trail segment be reduced to eight-feet in width to be consistent with the trail design approved in the adjacent subdivisions to the east (Condition #9). • Meandering Sidewalks. The proposed development plans include a series of sidewalks that meander into and out of the street right-of-way for the subdivision. Because this was a design element that was approved as part of the General Concept Plan review, Staff is recommending that the preliminary plans be approved with this design feature. Please note, however, that the City Engineer is not recommending the construction of any sidewalks outside of the right-of-way, and that additional requirements should be included as part of the City’s review in order to address the City Engineer’s concerns. Specifically, Staff is recommending that the developer provide a 10-foot drainage and utility easement over all private lots adjacent to sidewalks outside of the public right-of-way, and that any land located between the sidewalk and the street right-of-way be covered under a similar easement as well (Condition #6). • Landscaping and Tree Preservation. The landscape and tree preservation plans have been reviewed by the City’s consulting landscape architect, Stephen Mastey. The review memorandum submitted by the Landscape Consultant is found in Attachment #11. In the review memo, Mastey notes that the submitted Landscape Plan (L1-L6) and Tree Inventory and Preservation Plan comply with the City’s ordinances related to landscaping and tree preservation/replacement. It should be noted that the Landscape Plan as proposed includes street tree plantings on the outside of the sidewalk, as opposed to in between the street and sidewalk. As this location is typically reserved for private utilities, staff would recommend that the Landscape Plan be revised to locate all boulevard trees in between the street and the sidewalk (Condition #7). The requested modifications pertaining to plant location, as well as the identification of plant species, can be incorporated into the Final Landscape Plan. • Green Belt/Buffer. The Comprehensive Plan identifies an area north of the Boulder Ponds plat as a greenway/buffer space with a minimum width of 100 feet. Throughout the Boulder Ponds subdivision, the provided greenbelt complies with, and in many locations exceeds, the 100-foot greenbelt requirement. Consistent with City planning efforts, the applicant has included a trail improvement within the greenbelt to act as a linear park amenity. In addition, trail connections through this area will provide access to the Savona subdivision and beyond to the east and Stonegate Park in the west. It should also be noted that a large portion of the provided greenbelt is subject to a Northern States Power (Xcel Energy) easement. PUBLIC HEARING ITEM 4A – ACTION ITEM 11 • Streets. The proposed street system has been designed to comply with all applicable subdivision requirements and City engineering standards. The general street system of the Boulder Ponds development is designed to have a curvilinear aesthetic. As part of the subdivision, three cul-de-sacs are proposed. All of the proposed cul-de-sacs comply with the maximum length (600 feet) for cul-de-sacs in sewered residential subdivisions per the City’s Subdivision Ordinance. In addition, it should be noted that the applicants are proposing tear- drop or enlarged cul-de-sac with inner islands to provide additional visual interest and improved sightlines. In reviewing the design of the proposed cul-de-sacs, the Fire Chief and public works staff have voiced concern over the function and maintenance of the proposed design. However, the applicants have submitted turning radius exhibits (Attachment #7) demonstrating that emergency service vehicles are able to navigate the proposed islands. It should also be noted that the designs of the cul-de-sacs were discussed as part of the approval of the General Concept Plan. At that time, the Planning Commission and City Council supported the design of the proposed cul-de-sacs. Other comments from Staff concerning streets are as follows: o Secondary Access. The proposed development includes a new access to Hudson Boulevard that will be constructed as part of the first project phase, and will include the construction of a portion of 5th Street as well. Because there have been no approvals to date for any additional extensions of 5th Street, there is no set timeline for the creation of a secondary access point to the site. Because 5th Street will be built with adjacent subdivisions, Staff is not recommending any restrictions concerning the timing of project phases within Boulder Ponds. o 5th Street. The development plans have been prepared to comply with the City’s approved design for 5th Street with the exceptions listed in the City Engineer’s memorandum. The developer will be responsible to construct this minor collector road as part of the initial development plans, and in accordance with the phasing depicted in the attached plans. The final construction plans will need to include all lighting, landscaping, and other details as required by the City. The Comprehensive Plan calls for the future extension of 5th Street further to the west of the applicant’s property; however, in order to make this connection the owner of the property immediately to the west of the site (Bremer Financial Services) will need to give its consent to the proposed layout for 5th Street since it crosses through the extreme northeastern portion of its property in the Eagle Point Business Park. The attached application materials have been signed by Bremer Bank, which satisfactorily addresses this concern. • Street Names. Along with the preliminary plat and preliminary PUD plan, the applicants have submitted proposed street names that relate to the proposed name of the subdivision, Boulder Ponds. In developing the street names for the newly platted or developing areas of Lake Elmo, Staff has been utilizing the Washington County street naming system. The purpose of utilizing the County system is to provide emergency services and public works personnel knowledge of the general location of a property in cases of emergency or general public projects. While staff is sensitive to the applicant’s wish or desire to provide street names that reflect the theme of the proposed development, staff is recommending that the proposed subdivision adhere to the County street naming system to the best extent possible. As a condition of approval (Condition #4), Staff is asking that the applicant continue to work with the City at developing street names for the project, and that these names be included with the final plat submission. PUBLIC HEARING ITEM 4A – ACTION ITEM 12 • City Engineer Review. The City Engineer has submitted a detailed list of comments concerning the preliminary plat and plans as part of a memorandum to the City dated July 24, 2014, which includes a separate review of the 5th Street plans conducted by a transportation engineer from TKDA. While the report itself is quite lengthy, many of the comments pertain to relatively minor plan revisions or construction details that should not result in any significant changes to the preliminary plat document. For example, some of the comments concerning grading may impact the ability to build a home with a walkout basement (as opposed to a lookout basement), but would not otherwise alter the lots as proposed. Rather than restating all issues and concerns as identified by the City Engineer, Staff is recommending a condition of approval (Condition #5) that will require the applicant to address all comment from the City Engineer in subsequent plan reviews. • Fire Department Review. The Fire Chief has reviewed the plat and has submitted a review memorandum (Attachment #10) dated 7/23/14. Included in the Fire Chief’s comments is concern over the design of the enlarged “teardrop” cul-de-sacs. It should be noted that the applicants have submitted a turning radius exhibit to demonstrate that a ladder truck can effectively navigate the proposed cul-de-sacs. In addition to the concern over the cul-de-sacs, the Fire Chief has noted that the proposed street names for the subdivision do not comply with the Washington County street naming system, which the City has been utilizing for recently approved plats. Staff would recommend that the applicants work with City to determine appropriate street names for the subdivision in advance of Final Plat approval (Condition #4). • Watershed Districts. The project area lies within the South Washington Watershed District (SWWD). The Boulder Ponds project has already submitted a watershed district permit, and the permit has been conditionally approved. The conditions related to the watershed district approval include compliance with NPDES permitting requirement and verification of soil conditions rough on-site testing. Staff is recommending that adherence to the SWWD permit requirement be included as a condition of approval (Condition #3). Based on the above Staff report and analysis, Staff is recommending approval of the preliminary plat and preliminary PUD plan with 11 conditions intended to address the outstanding issues noted above and to further clarify the City’s expectations in order for the developer to move forward with a final plat and final PUD plan. The recommended conditions are divided into two categories to better communicate the purpose and intent of the conditions. The recommended conditions are as follows: Recommended Conditions of Approval: Pending Review and Approvals 1) The applicant must enter into a separate grading agreement with the City prior to the commencement of any grading activity in advance of final plat and plan approval. The City Engineer shall review any grading plan that is submitted in advance of a final plat, and said plan shall document extent of any proposed grading on the site. 2) The developer shall be required to submit an updated parkland dedication calculation in advance of Final Plat. Upon submission of the calculation, the applicant must work with the City to achieve the required parkland dedication amount per the City’s Subdivision Ordinance. The developer shall be required to pay a fee in lieu of park land dedication equivalent to the fair market value for the amount of land that is required to be dedicated for such purposes in the City’s Subdivision Ordinance less the amount of land that is accepted PUBLIC HEARING ITEM 4A – ACTION ITEM 13 for park purposes by the City. Any cash payment in lieu of land dedication shall be paid by the applicant prior to the release of the final plat for recording. 3) The developer must follow all the rules and regulations of the Wetland Conservation Act, and adhere to the conditions of approval for the South Washington Watershed District Permit. 4) The applicant shall work with the Planning Staff to name all streets in the subdivision in a manner acceptable to the City prior to the submission of final plat. Modifications to the Preliminary Plat and Preliminary PUD Plans 5) The Final Plat and Plans must include the requested modifications outlined in the City Engineer’s review memorandum dated 7/24/14. 6) In addition to standard easements require by the Subdivision Ordinance, additional drainage and utility easements must be provided extending 10 feet from meandering sidewalks, as well as all of the portion of private lots between meandering sidewalks and the public right-of- way. 7) The landscape plan shall be updated to locate all boulevards trees in between the public street and sidewalk to not interfere with private utilities. 8) All islands and medians shall be platted as part of the right-of-way and shall be maintained by the Home Owners Association. The applicant shall enter into a maintenance agreement with the City that clarifies the individuals or entities responsible for any landscaping installed in areas outside of land dedicated as public park and open space on the final plat. 9) The design of the northern buffer trail shall be modified to a width of 8 feet as opposed to the regional trail standard of 10 feet. 10) The plan and profile for the eastern limits of 5th Street shall match the preliminary development plans for the Savona Subdivision or will otherwise be revised in a manner to meet the requirements of the City Engineer. Plat Restrictions 11) Prior to recording the Final Plat for any portion of the area shown in the Preliminary Plat, the Developer shall enter into a Developers Agreement acceptable to the City Attorney that delineates who is responsible for the design, construction, and payment of public improvements. DRAFT FINDINGS Staff is recommending that the Planning Commission consider the following findings with regards to the proposed Boulder Ponds preliminary plat and preliminary PUD plan: • That the Boulder Ponds PUD General Concept Plan was approved by the City on December 17, 2013, and the submitted Preliminary Plat and Preliminary PUD Plan is consistent with the approved General Concept Plan. PUBLIC HEARING ITEM 4A – ACTION ITEM 14 • That the Boulder Ponds preliminary plat and preliminary PUD plan are consistent with the Lake Elmo Comprehensive Plan and the Future Land Use Map for this area. • That the Boulder Ponds preliminary plat and preliminary PUD plan generally comply with the City’s LDR- Urban Low Density Residential and MDR – Urban Medium Density Residential zoning districts. • That the Boulder Ponds preliminary plat and preliminary PUD plan comply with the City’s subdivision ordinance. • That the Boulder Ponds preliminary plat and preliminary PUD plan comply with the City’s Planned Unit Development Regulations. • That the Boulder Ponds preliminary plat and preliminary PUD plan comply with City’s Engineering Standards, except where noted in the review memorandum from the City Engineer dated 7/24/14. • That the Boulder Ponds preliminary plat and preliminary PUD plan comply with other City zoning ordinances, such as landscaping, tree preservation, and erosion and sediment control. • That the Boulder Ponds preliminary plat and preliminary PUD plan achieve multiple identified objectives for planned developments within Lake Elmo. RECCOMENDATION: Staff recommends that the Planning Commission recommend approval of the Boulder Ponds Preliminary Plat and Preliminary PUD Plan with the 11 conditions of approval as listed in the Staff report. Suggested motion: “Move to recommend approval of the Boulder Ponds Preliminary Plat and Preliminary PUD Plan with the 11 conditions of approval as drafted by Staff based on the findings of fact listed in the Staff Report.” ATTACHMENTS: 1.

In order to be flexible as market conditions dictate, we are requesting approval of 3 alternative site plans at the time of PUD/Preliminary Plat for Boulder Ponds. Generally, the alternatives allow for an empty nester-type product in place of the traditional single family homes. The alternate plans include three options; this request is to allow flexibility to implement one or all three as market conditions dictate. The Preliminary Plat proposes a total of 98 detached lots. The three options increase the lot count by 9 to a total of 107 lots. Below is a summary of each option: EXHIBIT A EXHIBIT B EXHBIT C Original lot count (as shown on Preliminary Plat) 18 26 10 Proposed lot count (as shown on Alt Plans) 20 31 12 Difference in lot count +2 +5 +2 Min. Setbacks (as shown on Preliminary Plat) Front: 20’ house/25’ garage Side: 5’ min/10’ avg Front: 20’ house/25’ garage Side: 5’ min/10’ avg Front: 20’ house/25’ garage Side: 5’ min/10’ avg Min. Setbacks (as shown on Alt Plans) Front: 20’/25’ front facing garage Side: 5’ Rear: 10’ to covered porch Front: 20’/25’ front facing garage Side: 5’ Rear: 10’ to covered porch Front: 20’/25’ front facing garage Side: 5’ Rear: 10’ to covered porch The goal in designing the alternative site plans was to create options that could introduce a different product type while preserving the spirit of the neighborhood, which includes curvilinear streets, meandering walks and varied setbacks. In response, narrower lots are proposed within the same street layout. The product is a single level detached home with association maintained grounds that is geared toward empty nesters. In keeping with the intent of the original proposed design, home placement on the lot is important to maximize view corridors. This is accomplished by angling the lots and varying the setbacks. Staggering the lots along with strategic window and interior room placement maximizes the view sheds from inside the home. Instead of looking in your neighbor’s home, views of the ponds and open space are achieved. Additionally, the lot layout allows most homes to have a side-loaded garage, which downplays this typically prominent feature of the home. Now, the entry becomes the focal point of the front elevation. This staggered, angled approach avoids the traditional row appearance to the streetscape making it more visually interesting. This is also evident along 5th Street, where the best side of the home is showcased. In summary, it is important to maintain product flexibility to meet the demands of changing demographics while upholding the intent of the underlying design concepts. This is what will make Boulder Ponds a success.   PAGE 1 of 6  MEMORANDUM         Date: July 24, 2014      To: Nick Johnson, City Planner  Re: Bolder Ponds

  STATUS/FINDINGS: Engineering review comments have been limited for the purpose of Preliminary Plat issues.  Additional Final Construction Plan review and comments will be provided once Preliminary Plat approval is  granted for the development. Engineering review comments are as outlined below.       PRELIMINARY PLAT     The construction of 5th Street North is required as part of the Bolder Ponds development. The construction  plans include 5th Street North as part of the Plan set. The Preliminary Plat must be revised to include the full  R/W area to accommodate the construction of 5th Street North, including the added R/W required from the  Bremer Financial Services property. This added area needs to be Platted as R/W.   The street median Outlots should be Platted as public R/W. The City should use maintenance agreements  with the HOA to facilitate the landscape maintenance of the median areas.  The Preliminary Plat should be  revised accordingly.   Additional R/W must be obtained along the east side of Cobblestone Plaza such that the R/W extends an  additional 80 feet, well past the Cobblestone Path intersection.   Additional easement is required to provide a minimum 30‐foot utility easement for the storm sewer pipe  run from CS‐600 to FES‐600C. Part of this easement must be acquired from the adjacent Eagle Point Town  Office property.   Additional easement is required to provide a minimum 30‐foot utility easement for the storm sewer pipe  run from CBMH 806 to CBMH 801.      FOCUS ENGINEERING, inc.  Cara Geheren, P.E.  651.300.4261

Sanitary sewer and watermain stubs to adjacent property and pipe oversizing will continue to be reviewed  by City staff as the development progresses forward and oversizing routes may need to be changed as part  of the final construction plans. Sewer and watermain oversizing is paid by the City as a reimbursement  addressed within the development agreement.   Sewer oversizing may be required from Hudson Boulevard to the Azur property or an 8‐inch sewer  may need to be stubbed north on 5th Street to the Azur property.   The 12‐inch watermain oversize is appropriate as shown on the proposed plans. Additional  oversizing may need to be extended to the site of Well No. 3, pending further staff review.   The 12‐inch watermain stub location at Outlot Q must be coordinated with Lennar to verify that  the stub is placed in the appropriate location.    Sewer and water stubs may be needed to the north edge of the Lampert Lumber and or Cranky Ape  properties.   Sewer and water stubs may be needed from 5th Street to Outlot N for service to the property south  of Bremer Financial Services.    Sanitary sewer and watermain stubs have been proposed along Cobblestone Plaza to serve future  commercial developments at Outlots K, J and M. The size and location of these stubs require further review  with the applicant.   Detailed Sanitary Sewer and Watermain construction plans were submitted as part of the Preliminary Plat  application. A detailed construction plan review will be completed upon Preliminary Plat approval.  However, comments below have been provided for the applicant’s use and information:   Hydrant and system valve placement will be made per City standards and as laid out by City staff.  Applicant shall submit an overall watermain plan for staff redlines.   Utility alignments will be necessary to better maintain the sewer and water within the street  section, in particular in areas where the street meanders or divides. Sanitary sewer MH’s must be  moved to centerline or center of drive lanes (i.e. MH 10, MH 23 and MH 36).   Utility alignments will be necessary to eliminate or minimize the use of watermain insulation.  Watermain insulation will only be allowed when alignment alternatives are not available.  Watermain shall be placed to maintain appropriate storm sewer pipe separation.   Sanitary sewer along Boulder Ponds Parkway may terminate after the service stub to Lot 11, Block  4, eliminating roughly 60 feet of sewer pipe.   Sanitary sewer along Pebblestone Place may terminate after the service stub to Lot 8, Block 4,  eliminating roughly 70 feet of sewer pipe.   Sewer and water service stubs should be revised to eliminate bends and shall be perpendicular to  the street whenever feasible.   Stationing must be added to all profiles.   Profile elevation labels must be corrected for accuracy.   The existing watermain must be shown in plan and profile along Hudson Boulevard.   Correct “Existing Ground” and “Proposed Grade” call‐outs on Sheet 9, Pebblestone Ridge Cove –  12” Watermain Loop Profile.   Add hydrant at 12” plug on 5th Street (at approximate STA 21+90) for flushing purposes.   Add vertical bends to accommodate severe grade changes at the Pebblestone Place watermain  loop.      GRADING, STORM WATER MANGEMENT AND EROSION CONTROL AND STORM SEWER SYSTEM     Preliminary Plat approval should be contingent upon additional plan revisions needed to provide a grading  plan, storm water management plan and storm sewer system that complies with the requirements of the  City of Lake Elmo Engineering Design Standards Manual.     PAGE 3 of 6   Grading plans must be resubmitted to include existing and proposed contours for a distance of 150 feet  from all edges of the proposed Plat. Staff review can continue upon receipt.   Relocate Outlot L retaining wall to Outlot M. This should be owned privately, not by the City.   Outlot M retaining wall requires greater separation from the proposed storm sewer pipe.   Permission to grade and install storm sewer pipe is required from the adjacent Eagle Point Town Office Park  for infrastructure behind Lots 9 and 10, Block 1, First Addition and potentially for the storm sewer run from  this location to Hudson Blvd.   There are three new proposed storm water discharge points to Hudson Boulevard:   Two new discharges to the south side of Hudson Blvd requires MnDOT permission. This permission  is required before plan approval can be provided and any grading work can begin.   One discharge point is along the north side of Hudson Blvd. owned by the City. Additional detail is  needed before the City can determine acceptance of this new storm water discharge.   Lot 1, Block 1, Second Addition does not conform to City requirements for flood protection from Infiltration  Basin 3C. The lot building type or grading for this lot and adjacent Outlot must be revised accordingly.   Storm sewer pipe alignments must be revised to better maintain the storm sewer within the street  footprint. Areas include:   Bolder Ponds Parkway, between Outlot F and 5th Street.   Pebblestone Place, from Bolder Ponds Parkway to cul‐de‐sac.   Pebblestone Terrace, near the cul‐de‐sac.   Storm sewer must be a minimum of 15 feet from proposed retaining walls (near MH 1004).   Storm sewer catch basins should be relocated from corners per the City standard details.   All proposed pipe crossings must be perpendicular to street alignment (i.e. CB 516A and CB 515A).   Infiltration basin 2A Retaining Wall should be eliminated or relocated onto the adjacent private property.  It appears that the wall can be eliminated if the adjacent lot is not a walk out. It is not recommended that  the City take on ownership of this retaining wall.   The double retaining walls located in the Xcel Transmission easement area should be eliminated or  relocated onto the adjacent private property. It appears that the walls can be eliminated if the adjacent lots  are not walk out lots. It is not recommended that the City take on ownership of these retaining walls.   The HWL must be provided for Infiltration Basin 1B.   The storm sewer system or grading plans must be revised to provide the City standard minimum pipe cover  of 3.5 feet. Changes must be made as part of the final construction plans. Several structures or pipe runs  do not meet this minimum, but it appears these changes can be made without impact to the Plat.   Drain tile is required as part of the City standard street section at all localized low points in the street. Drain  tile considerations may impact the storm sewer design and depth requirements at low points.   Storm sewer castings must comply with City of Lake Elmo Design Standards (i.e. proposed beehive castings).   The watershed has indicated that additional testing is required to verify the assumed infiltration rates at  each basin. The City standard is to require multiple tests at each location and not allowing tests taken in  the vicinity. Plan revisions may be required if rates do not support the design assumptions.    The plan must be updated to indicate wetland buffers for staff review.        STREET, SIDEWALK AND TRAIL PLANS    5TH STREET NORTH:     5th Street seeks to become the backbone of future development along the I94 corridor, essentially  becoming the primary access in and out of the future neighborhoods. The street is required for the sole  purpose to provide mobility to support the growth and development within the corridor. The quality of the  street and its connections are critically important. The purpose of the proposed street standards are to 1)  improve the function, mobility and appearance of the street, 2) encourage pedestrian and bicycle use, and  3) reduce the potential for speeding.    PAGE 4 of 6   The plan indicates a minimum 100 foot R/W as required, except for the additional R/W to be acquired from  Bremer Financial Services. This area must be Platted as public R/W.   The proposed  2‐lane collector Parkway street (5th Street) design and geometrics must meet all Municipal  State Aid design standards for urban streets (8820.9936) for ADT > 10,000; 40 mph design speed; and must  be consistent with the detailed Parkway cross section installed throughout the remaining corridor  segments.    The plans must include the City standard typical cross sections for 5th Street to ensure construction details  are followed accordingly, including turn lane configurations.   The proposed alignment is consistent with the State Aid design intent. However, the proposed plan  indicates impacts to adjacent properties. The applicant must coordinate the design of 5th Street with each  adjacent property and must show the proposed plan and profile for a distance of 150 feet beyond the Plat  for both Azur properties/Bremer and Lennar/Alan Dale. The matching profiles must be agreed to by all  impacted properties.   Access spacing to 5th Street meets the guidelines for the Cities Transportation Plan. A full access is proposed  at Boulder Ponds Parkway near the middle of the Plat and a partial access with Boulder Ponds Parkway at  the north end. Additional access to 5th Street is not recommended throughout the remaining corridor. It is  recommended that potential future access by Lampert Lumber and/or Cranky Ape properties be through  Boulder Ponds Parkway or a future street to the east, then to 5th Street as part of a full access.   The signing and striping plan for 5th Street, Sheet SS1, must be updated to meet state aid standards and the  5th Street typical section detail for turn lanes. Signage and pavement markings for cross walks should meet  the City standard for cross walk markings.   It is recommended that the 5th Street trail and sidewalks maintain the consistent boulevard alignment and  layout per the City approved 5th Street typical section.   The trail and sidewalk intersection crossings should occur within the R/W at the corners (see  attached TKDA Traffic Engineering review memo). 5th Street does not have a stop condition and  therefore the safer pedestrian crossing locations will be at the intersection corners.   The sidewalk along the south of 5th Street should connect the median walk to the west boulevard  walk.   The second crosswalk should be provided along the east side of the 5th Street/Boulder Ponds  Parkway and the signing and striping plan updated accordingly.    Pavement marking crosswalks should also be added for east‐west crossings.   A second 5th Street pedestrian crossing location should be considered near the north end of the  Plat at the Xcel Transmission easement area before 5th Street begins the next horizontal curve into  Azur properties.   Per the TKDA Traffic engineering review memo, the 5th Street and cross street medians must be adjusted  so that they do not extend into the intersection. Medians should terminate at the cross street curb line.  The proposed medians interfere with left turn movements and plowing operations.   Revise the 5th Street vertical sag curve to K=64 at STA 14+50. Minimum sag curve for 40 mph road is 64.   Corner curb radius must be 25 feet at 5th Street and must be shown on the plans.   Additional streetscape amenities are required along 5th Street consistent with the remaining corridor  segments and the City design standard for 5th Street.    A detailed review of these plans are completed by the City’s Landscape Architect.   The plans must be detailed and dimensioned to indicate the specific locations for all trees, light  poles, signs and utilities. This R/W corridor is very tight and specific spacing between amenities is  critical to a successful design. A 2‐foot clear zone must be maintained on each side of the trail and  sidewalk at all locations to meet state aid design standards.      HUDSON BOULEVARD TURN LANE:   Dedicated turn lanes are being provided along Hudson Boulevard to access the development at  Cobblestone Plaza. The signing and striping plan for Hudson Blvd, Sheet TL1, must be updated to meet the  current posted 50 mph design speed.      PAGE 5 of 6  RESIDENTIAL STREETS   The applicant is proposing a roadway configuration that is generally acceptable and in accordance with City  standard requirements. Primary and secondary access appears adequate for the site.    The plan indicates that residential streets are being proposed to a 28 foot width from back of curb to back  of curb. Surmountable concrete curb and gutter are proposed in single family residential areas and B618  curb is proposed in commercial and multi‐family areas.    The plan indicates a minimum 60 foot R/W as required.   The residential streets propose several medians that spilt the traffic into 2‐one way drive lanes. It is  recommended that plans be revised such that each lane is a minimum of 20 feet from face of curb to face  of curb to meet minimum fire lane requirements.    The intersection of Pebblestone Terrace and Pebblestone Place create a very unique and unfamiliar  intersection.   Turning templates must be submitted to verify appropriate curb radius at all median curb corners  and curb radius lengthened when required (i.e T‐S and H‐I).   The sidewalk crossing(s) at this intersection must be reviewed and relocated to provide safe  crossing(s) with snow storage considerations. The proposed crossing at Outlot F is not  recommended.   The intersection of Cobblestone Path should be moved south as far as possible to provide added separation  from the median at Outlot I. This becomes more important if a full access is contemplated in the future to  serve the Cranky Ape and Lampert Lumber properties.   Consideration should be given to shortening the Outlot I median.   The R/W along the east side of Boulder Ponds Parkway, across from Cobblestone Path, should be  extended further south at least 80 feet to facilitate a potential future road connection.     Corner curb radius must be indicated on the plans. For local streets a 20‐foot radius must be used.   Minimum K‐value for sag curves is 37. Revise sag curves along Pebblestone Place, Pebblestone Terrace, and  Pebblestone Ridge Cove. Grades between 1+00 and 3+50 along Pebblestone Terrace should be revised to  create a smoother transition and lesson the 5.45% grade, in particular since this road grade is a result of  the area being filled.     Minimum K‐value for crest curves is 19. Revise crest curve along Pebblestone Ridge Cove. Grades along this  road should be somewhat reduced, in particular since the area is being filled.   The Pebbelstone Ridge Cove Plan View on sheet 24 must be revised to plan scale to facilitate plan review.   Cul‐de‐sac geometry must be revised as follows:   The pavement width must be a minimum of 20 feet from face of curb to face of curb around cul‐ de‐sacs to accommodate emergency vehicle access.   With a 20 foot minimum pavement width, all cul‐de‐sacs must be signed as “No Parking Any Time”.   The proposed cul‐de‐sac medians show a tear drop design at the cul‐de‐sac entrance. The tear drop  must be revised to create a more rounded median to better facilitate snow plowing and emergency  access.    BOULEVARD LAYOUT ALONG RESIDENTIAL STREETS   Applicant is proposing a non‐standard boulevard layout which is not consistent with several City design  standards. It should be the applicant’s responsibility to submit proposed alternative design details as part  of the plan set that replaces the City standard design details that are not being met. This is required to detail  the proposed design both for City review and for construction purposes. Multiple details will be required  for the various boulevard layouts.   Construction plans must also be completely detailed for each varying condition because it cannot be left to  the various contractors to field locate all the different infrastructure components that must be closely  coordinated within the R/W corridor. Additional plan details must be submitted for staff review.   Meandering sidewalks and trails are proposed throughout the development. Sidewalks and trails outside  of the R/W create on‐going operation and maintenance difficulties. The following is strongly recommended  if the sidewalks are allowed to meander outside of the R/W:    PAGE 6 of 6  

of Lake Elmo From: Bryant Ficek Project No.:15545.000 Date: June 27, 2014 Routing: Geometric plans and cross sections for the proposed 5th Street corridor of the Boulder Ponds development were sent for our review on June 18. In addition to the plans, the City’s desired typical sections and design guidelines were provided. Per your request, this information was reviewed in terms of conformance to State Aid standards. The design of the medians at intersections and the locations of crosswalks were additional issues raised for our review. The provided information is attached to this memorandum for reference. The proposed development is located on the north side of I-94 and the Hudson Boulevard frontage road, between Inwood Avenue and Keats Avenue. As identified in the City’s Transportation Plan of the 2030 Comprehensive Plan, a future collector roadway is expected to be located about halfway between 10th Street N and Hudson Boulevard. This new road is expected to provide for east-west travel between Inwood Avenue and Keats Avenue and beyond. The projected daily volume for this new roadway is 5,000 vehicles. The proposed development’s 5th Street is anticipated to become part of that new collector roadway. State Aid Standards The MnDOT State Aid office provides design guidance in terms of lane widths and other roadway design details. Satisfaction of these guidelines means that a roadway is eligible to become a State Aid route, which then makes the road eligible for future maintenance and improvement funding. Based upon the information provided, the design of 5th Street meets the City’s desired standards, which also satisfy the State Aid standards. The provided right-of-way, lane widths, and median widths meet or exceed the State Aid minimums, assuming a posted speed limit of 40 mph or less. Horizontal and vertical curves also meet the minimum standards for a 40 mph roadway. Pavement sections were not provided to check against the State Aid standard of a 9-ton roadway. However, the City’s desired standards call for a 10-ton roadway. Assuming that 5th Street continues to match the City’s desired standards, this detail would also satisfy the State Aid standards. Memo Page 2 June 27, 2014 Boulder Ponds Development Traffic Review City of Lake Elmo   Pedestrian Movements The design shows a 10-foot trail on one side of 5th Street and a 6-foot sidewalk on the other. A wide boulevard separates the trail and sidewalk from the road except where right-turn lanes are introduced. Based on our review of the layout of the trail and sidewalk, our comments are: • The trail moves away from 5th Street at intersections, providing approximately 30 feet between the pedestrian crossing area and the vehicle stopping point. This is similar to pedestrian crossing treatments at roundabouts, allowing vehicles to focus on pedestrian movements first, followed by a focus on other vehicle movements. At stop controlled intersections, this approach is acceptable. Appropriate signing and striping should be used to notify drivers of the pedestrian crossing area. • Only one crossing of 5th Street is shown, on the west side of the Boulder Ponds Parkway intersection. Assuming that this intersection is under side-street stop control, with 5th Street traffic not stopping, the crossing should be located at the intersection rather than set back approximately 30 feet as shown. When traffic will not stop or slow at the intersection, setting the pedestrian crossing back in this manner does not offer benefits to the driver or the pedestrian. • Additional crossings of 5th Street should be considered, including mid-block crossings. Connections to and from development outlots not at intersections could also be considered. For instance, a sidewalk/trail connection linking outlot C to the trail on the north side of 5th Street with a mid-block crossing to the sidewalk on the south side of 5th Street may provide additional benefits for those residents. Proper signing and striping should be used for all crossings to improve safety. • At all crossings, the ramp to and from the roadway should be properly designed using the latest ADA standards. The provided plans do not uniformly identify pedestrian ramps at each crossing point, nor do they provide information regarding the pedestrian ramp design for those that are identified. • The south crossing of Boulder Ponds Parkway is not continuous across the intersection. Pedestrian routes should be reviewed to ensure that the routes are continuous and do not strand a pedestrian in a potentially dangerous situation, such as the middle of an intersection. Medians As mentioned, the raised median on 5th Street meets the City’s desired standards in addition to the minimum State Aid standards. At the intersections, the minimum 4-foot width (face-of-curb to face-of-curb) is sufficient for those standards. However, a minimum width of 6 feet is desired if the median is to be used as a pedestrian refuge at crossing locations. A minimum width of 6 feet is also better in terms of space for sign mounting. The minimum 6-foot width could be achieved by reducing the left-turn lane and through lane to 11-foot widths at the intersections. This change in lane width would still satisfy State Aid standards. Memo Page 3 June 27, 2014 Boulder Ponds Development Traffic Review City of Lake Elmo   Vehicle turning movements should be considered at the intersections in regard to the median design as well. As currently shown in the plans, the median on 5th Street extends too far into the intersection and would interfere with left turn and through movements from the side streets.
