The site is presently developed with a manufactured home and a detached garage. The subject site is zoned R-3, Residential — Long Range Urban Service Area District and single family uses are a permitted use in this District. Section 19 of the Zoning Ordinance requires consideration of a conditional use permit (CUP) for relocation of existing buildings to lots within the City. Exhibits: A. Site Location B. Site Plan C. New Home Photos ANALYSIS Existing Structure. The applicant is proposing to remove the existing manufactured home from the property, but the detached garage is proposed to remain. Removal of the existing structure will be required prior to issuance of a permanent occupancy permit for the relocated dwelling. Building Relocation. The relocation of existing structures to lots within the City of Otsego requires compliance with the performance standards outlined in Section 20-19- 2, as follows: A. Upon relocation, the building shall comply with applicable requirements of the State Uniform Building Code. Comment: A building permit is required prior to relocation of any structure. Review and approval of the Building Official for conformance with the Uniform Building Code shall be made a condition of approval. B. The proposed relocated building shall comply with the character of the neighborhood in which it is being relocated, as determined by the City Council. Comment: The neighborhood is fully developed with single family dwellings consisting of a mix of manufactured housing and wood frame structures. The structure to be located on the property is a newer -style manufactured home and will be consistent with this character. C. The relocated use will not result in a depreciation of the neighborhood or adjacent property values. Comment. Because the structure has a similar character as adjacent dwellings and is in conformance with applicable performance standards, no depreciation is anticipated. D. The relocated structure shall be similar to the market valuation of adjacent principal structures as determined by the City or County Assessor. Comment: The structure currently on the property has an assessed market value of $13,200. The average market value of several properties (land and buildings) adjacent to the subject site, within Block 1 of Walesch Estates 2"d Addition, is determined to be $148,940 according to Wright County assessment data. Although no tax info was provided on the relocated structure, it is expected to have a value at least comparable to other properties in the area based on similar construction, size and compatibility with applicable performance standards. E. The relocated structure shall be ready for occupancy within six (6) months from the date of location on site. Comment: This requirement will be made a condition of approval. Lot Standards. The applicant has submitted a site plan indicating the proposed location of the relocated home in relation to 88th Avenue NE. The site plan also shows_ the approximate locations of the existing home and detached garage. The following table illustrates required performance standards for single family lots and dwellings in the R-3 District. 2 As shown on the submitted site plan, the proposed new home location complies with the required setbacks for the R-3 District. Single Family Dwelling Standards. Section 20-17-11 of the Zoning Ordinance establishes minimum design standards for single family uses, which apply to this application. The basic requirements are for a perimeter foundation, minimum dimensions of 30 feet by 24 feet, a shingled roof and minimum overhangs of 1 foot. Based upon the photo exhibits and other information provided by the applicant, the structure to be located to the property is in conformance with these requirements. CUP Criteria. When considering CUP applications, the Planning Commission and City Council must also take into account the possible adverse impacts of the building relocation based upon, but not limited to, the following factors outlined in Section 20-4- 2.F of the Zoning Ordinance: The proposed action's consistency with the specific policies and provisions of the official City Comprehensive Plan. Comment: Stated in the City's Comprehensive Plan is that `the character of individual neighborhoods shall be reinforced, maintained and upgraded" the proposed CUP proposes to upgrade the existing dwelling unit by replacing it with a newer, more spacious structure. 2. The proposed use's compatibility with present and future land uses of the area. Comment: The surrounding area is developed with low density, single family residential uses which are planned to continue as discussed in the Comprehensive Plan. Thus, the proposed use will be compatible with present and future land uses. 3. The proposed use's conformity with all performance standards contained in the Zoning Ordinance (i.e., parking, loading, noise, etc.). Comment: As noted above, the subject site and relocated structure comply with all applicable performance standards. 4 The mmnncarl IICP'C effer-t hpnn the oroo in \AIk;/ k i4 r. -r-- ul V" 111 VVI mali Il ic) til V'.JjoO-U.

Comment: The relocated dwelling and single family use of the property may be considered an improvement of the property from its existing condition and, as such, it will likely have a positive effect on the neighborhood. 3 5. The proposed use's impact upon property values of the area in which it is proposed. Comment: Although no study has been completed, the proposed use is not anticipated to negatively impact area property values. 6. Traffic generation by the proposed use in relation to the capabilities of streets serving the property. Comment: The relocated structure will access off of 88th Avenue NE, as the previous dwelling did, and will not generate traffic beyond the capabilities of streets serving the subject property. 7. The proposed use's impact upon existing public services and facilities including parks, schools, streets, and utilities and its potential to overburden the City's service capacity. Comment: The proposed use is not anticipated to have a negative impact to the City's service capacity. Utilities. The applicant is proposing to install a new on-site septic system and well, which are shown on the site plan. The applicant has stated that the new septic system and well will be installed following the building relocation. As such, it is not anticipated that the relocation will have any impacts on the septic system and well. However, the drainfield area must be protected from construction traffic during the relocation process. The systems will be subject to review and approval by the Building Official to ensure that they are installed properly and adequate to accommodate the proposed single family home. Security. Section 20-19-3 of the Zoning Ordinance requires that a security be posted for the relocation of existing structures. This security is required in part to cover any costs that may be incurred due to damage during the relocation, as well as to encourage completion of the project. The security shall be determined by the building official and will be required as a condition of approval. RECOMMENDATION The proposed relocation of an existing single family dwelling to 14123 88th Street NE is an improvement of the nronerty and is cnnsistpnt with rPni iramantc fnr hi ii1dinn relocations based on the information that has been provided by the applicant. The request is consistent with the Comprehensive Plan policies which support and encourage improvements within existing neighborhoods. As such, our office recommends approval of the requested CUP, subject to the conditions outlined below. 51 POSSIBLE ACTIONS A.

The DNR does not believe the necessary applications were processed to allow for City approval of the Featherwind Farms preliminary plat and final plats with lots subject to the standards of the R -C, Residential Rural Open Space Cluster District for portions of the site within the WS, Wild Scenic Recreation River Overlay District. The lot area and width requirements of the R -C District are less than the lot area and width requirements of the WS District. The City and Shadow Creek Corporation (the developer) have agreed to address this issue by processing a variance from the requirements of Section 20-95-7.C.1 of the Zoning Ordinance establishing the minimum lot area and width requirements of the WS District. Fyhihitc- A. Approved Preliminary Plat B. Alternative subdivision sketch ANALYSIS The Featherwind Farms Final Plat approved by the City Council on 27 February 2006 has 64 lots having home sites within the WS District. The table below illustrates the lot requirements of the R -C District and WS District: Minimum Lot Area Minimum Lot Width R -C District 1.0ac. net 100ft. WS District 2.5ac.(gross) 200ft. All of the lots within the Featherwind Farms Final Plat conform to the minimum lot area and width requirements of the R -C District. The 64 lots having home sites within the WS District do not conform to the WS District minimum lot area and width standards. The developer has submitted a sketch plan to show a potential subdivision of the subject site in compliance with the minimum lot area and width requirements of the WS District. The sketch plan locates 64 building pads within the WS District. More significantly, the sketch plan illustrates a loss of the 168.47 acres of permanent open space outlots provided for with the approved final plat, including the 63.86 acres immediately adjacent to the Mississippi River and including the 400 foot deep scenic easement acquired previously by the DNR. The subdivision of the property as shown on the sketch plan would result in more limited water access opportunities for residents within the subdivision and the general public and because of the fragmented property ownership, make more difficult preservation of the shoreline areas in a natural state. To this end, approval of a variance from Section 20-95-7.C.1 of the Zoning Ordinance is requested to allow for those lots of the Featherwind Farms Final Plat within the WS District to have a minimum lot area and width compliant with that required in the R -C District. Consideration of the requested variance is subject to the criteria established by Section 20-95-21 and Section 20-6-2.13 of the Zoning Ordinance. These criteria require a finding that the strict enforcement of the requirements of the Zoning Ordinance will cause an undue hardship that is not the result of actions by the applicant. Furthermore, the granting of the variance must be consistent with the intent, if not the letter of the Zoning Ordinance requirements from which the variance is being sought. The subject site is within the Rural Residential Preserve Area established by the Comprehensive Plan for the purpose of maintaining rural character and preservation of innate natural amenities and resources in the area of the City north of CSAH 39 west of Nashua Avenue generally corresponding to the WS District. The City established the R- C District based on these goals to allow for limited, rural density development that simultaneously provides for establishment of permanent open spaces and protection of significant environmental resources. Subdivision of the subject site in the manner set forth by the submitted sketch plan would be inconsistent with the objectives of the Comprehensive Plan and R -C District as well as the intent of the WS District. Compliance with the minimum lot area and width requirements of the WS District does result in an undue hardship; not one borne by the developer, but by the community for the inability to realize the stated goals of the Comprehensive Plan for natural resource protection and preservation of rural character in this area of the City. RECOMMENDATION Our office recommends approval of the variance allowing those lots of the Featherwind Farms Final Plat within the WS District to be allowed a minimum lot area and width as required by the R -C District. POSSIBLE ACTIONS A. Motion to approve a variance from Section 20-95-7.C.1 of the Zoning Ordinance based on a finding that compliance with the regulation causes an undue hardship in preserving rural character and protecting significant natural resources, including the shoreline of the Mississippi River consistent with the goals and policies of the Comprehensive Plan. B. Motion to deny the request based on a finding that the request is inconsistent with the Comprehensive Plan and the criteria for approval of a variance as set forth by the Zoning Ordinance. C. Motion to table. C.

DATE: 15 March 2006 BACKGROUND CITY FILE: REVIEW DATE 2006-15 15 May 2006 Mississippi 39, LLC is seeking approval of a preliminary plat for a single family subdivision on a 141 acre parcel located north of CASH 39 and east of Mason Avenue NE. The development proposal consists of 45 single family lots to be developed under the requirements of the R -C, Residential Rural Open Space Cluster District. The subject site is guided for rural residential uses by the Comprehensive Plan and is currently zoned A-1, Agricultural Rural Service Area District. Portions of the subject site are also within the boundaries of the Wild, Scenic and Recreational River District (WS District) of the Mississippi River. Consideration of the proposal requires a Zoning Map amendment to rezone the subject site from A-1 District to R -C District and approval of a preliminary plat. The applicant has also requested approval of a PUD/CUP to allow for the establishment of lot widths which are inconsistent with the requirements of the R -C District. Additionally, a variance from Section 20-95-7.C.1 of the Zoning Ordinance is requested to allow for the proposed lots within the WS District to have a minimum lot area and width compliant with that required in the R -C District. Finally, the City must vacate portions of the original Otsego Town plat underlying the subject site prior to approval of the request. The developer had previously received approvals for a Zoning Map amendment, CUP for transferred development rights and a preliminary plat for the west 59.8 acres of the subject site. The approved preliminary plat included 20 single family lots. The developer is seeking to replat the original development parcel with additional lands acquired to the east necessary to provide required access to the development at locations consistent with Wright County spacing requirements along CSAH 39. If approved, the current applications will supersede the previous preliminary plat approval. Exhibits: A. Site Location B. Existing Conditions C. Preliminary Plat D. Grading Plan E. Utility Plan F. Landscape Plan G. Phasing Plan ANALYSIS Zoning. In addition to the request for a CUP for the transfer of development rights, the proposed subdivision requires approval of a Zoning Map amendment to rezone the subject site from A-1 District to R -C District. The requests for a Zoning Map amendment and CUP are to be evaluated based upon (but not limited to) the criteria outlined in Section 20-3-2.F and 20-4-3.F of the Zoning Ordinance, respectively: The proposed action's consistency with the specific policies and provisions of the official City Comprehensive Plan. Comment: The Comprehensive Plan establishes the rural residential preserve within this area of the City to encourage development of unique single family neighborhoods that incorporate natural or rural character elements. This type of development is especially appropriate for areas included in the Mississippi River Wild, Scenic and Recreational River District in terms of density and opportunities for access to the Mississippi River. The proposed development is consistent with the intent of the Comprehensive Plan. 2. The proposed use's compatibility with present and future land uses of the area. Comment: The table below summarizes the surrounding land uses. As indicated in the table, the proposed development will be compatible with existing and future land uses in the immediate area. Direction I Land Use Plan I Zonina_ Map Existina Use North NA NA Mississippi River East Rural Residential A-1 District Single Family South Agriculture A-1 District Agriculture Single Famil West Rural Residential I R -C District Featherwind Farms 4 3. The proposed use's conformity with all performance standards contained herein (i.e., parking, loading, noise, etc.). Comment: The proposed use will be required to conform to the open space, neighborhood and general development standards of the R -C District. 4. The proposed use's effect upon the area in which it is proposed. Comment: The proposed development furthers the implementation of the R -C District and the development of unique residential neighborhoods within the rural residential preserve area. 5. The proposed use's impact upon property values of the area in which it is proposed. Comment: Although no study has been completed, the proposed use is not anticipated to have a negative impact on area property values. 6. Traffic generation by the proposed use in relation to capabilities of streets serving the property. Comment: The subject site is accessed via CSAH 39, which is a major arterial roadway. CSAH 39 has adequate capacity to accommodate traffic generated by the proposed 45 dwelling units. 7. The proposed uses's impact upon existing public services and facilities including parks, schools, streets and utilities and its potential to overburden the City's service capacity. Comment: The proposed development is not anticipated to have a negative impact upon the City's service capacity. Density. The R -C District allows up to 12 dwelling units per 40 acres, or a maximum of 15 dwelling units per 40 acres if transferred development rights are approved. With 45 proposed dwelling units on 141 acres, the density of the development is 13.8 dwelling units per 40 acres. A CUP was approved with the initial preliminary plat application to allow three dwelling units to be transferred to the subject site. As such, the proposed density of the development would be consistent with the requirements of the R -C District. Approximately 121.5 acres of the subject site is within the WS District. Development density within the WS District is limited to one dwelling unit per 2.5 acres. This density requirement would allow for 48 dwelling units within the WS District. As the applicant is proposing a total of 45 dwelling units, the development is compliant with the WS District density standards. Access. The subject site is to be accessed from CSAH 39 via extensions of Mason Avenue NE and Naber Avenue NE. The developer is also proposing to leave an existing roadway leading to an existing home which is proposed to remain, located to the east of the exception parcel. This existing roadway will provide another egress/ingress point for the subdivision as well as the existing property. There will be a total of three access points for the proposed subdivision. A divided rural section roadway with an oversized, landscaped median is proposed along Naber Avenue for approximately 320 feet north of CSAH 39 to the intersection with the east -west collector road for the development. The applicant has provided a landscape plan for this median. Open Space. The R -C District requires that a minimum of 50 percent of the net area of a proposed development be set aside as permanent open space. The preliminary plat identifies a new buildable area of 118.13 acres, therefore requiring 59.1 acres of open space. The proposed preliminary plat illustrates 59.11 acres of neighborhood recreation open space, which is consistent with the requirements of Section 20-60-7 of the Zoning Ordinance. This area is to be retained by the homeowner's association and a landscape planting and maintenance plan is required as a condition of approval. Lot Area/Width. The table below illustrates the lot requirements of the R -C District and WS District applicable to the subject site: Minimum Lot Area Minimum Lot Width R -C District 1.0ac. (net) 100ft. WS District 2.5ac. (gross) 200ft. All of the lots within the preliminary plat conform to the minimum lot area requirements of the R -C District. All proposed lots meet the required 100 foot lot width as measured at the front setback line, except for Lots 31, 32, 44, and 45. These irregularly shaped lots are necessary to accommodate existing dwellings and each parcel has adequate building area. The City has approved irregular lot shapes within the R -C District for other developments to accommodate existing dwellings or provide access to unique views. Since the applicant is requesting a PUD/CUP as a part of the preliminary plat application, these irregular lot shapes are permissible. All of the proposed lots are within the WS District and all but two do not conform to the WS District minimum lot area and width standards. The developer has submitted a sketch plan to show a potential subdivision of the subject site in compliance with the minimum lot area and width requirements of the WS District. The sketch plan locates 45 lots within the WS District. More significantly, the sketch plan illustrates a loss of the 59.11 acres of permanent open space outlots provided for with the approved final plat, including the 20.66 acres immediately adjacent to the Mississippi River. The subdivision of the property as shown on the sketch plan would result in more limited water access opportunities for residents within the 2 subdivision and the general public and because of the fragmented property ownership, make more difficult preservation of the shoreline areas in a natural state. To this end, a variance from Section 20-95-7.C.1 of the Zoning Ordinance is requested to allow for those lots within the WS District to have a minimum lot area and width compliant with that required in the R -C District. Consideration of the requested variance is subject to the criteria established by Section 20-95-21 and Section 20-6-2.B of the Zoning Ordinance. These criteria require a finding that the strict enforcement of the requirements of the Zoning Ordinance will cause an undue hardship that is not the result of actions by the applicant. Furthermore, the granting of the variance must be consistent with the intent, if not the letter of the Zoning Ordinance requirements from which the variance is being sought. The subject site is within the Rural Residential Preserve Area established by the Comprehensive Plan for the purpose of maintaining rural character and preservation of innate natural amenities and resources in the area of the City north of CSAH 39 west of Nashua Avenue generally corresponding to the WS District. The City established the R- C District based on these goals to allow for limited, rural density development that simultaneously provides for establishment of permanent open spaces and protection of significant environmental resources. Subdivision of the subject site in the manner set forth by the submitted sketch plan would be inconsistent with the objectives of the Comprehensive Plan and R -C District as well as the intent of the WS District. Compliance with the minimum lot area and width requirements of the WS District does result in an undue hardship; not one borne by the developer, but by the community for the inability to be able realize the stated goals of the Comprehensive Plan for natural resource protection and preservation of rural character in this area of the City. Setbacks. The following table outlines the required building setbacks for lots within the R -C District and the setbacks being proposed in the subject development. As shown in the table, the proposed setbacks comply with the requirements of the R -C District and WS District. There is an existing home, located within the proposed Lot 33, which does not meet the required bluffline setback. However, because this is an existing structure it is considered to be non -conforming and is therefore not required to comply with the current bluffline setbacks. The submitted plans do not indicate the OHWM of the Mississippi River. As a condition of approval, the applicant shall be required to illustrate the OHWM on the plat showing that the proposed building sites are compliant with the required setback. Blocks. The proposed single family lots are proposed to be platted as one Block. Section 20-6-7 of the Zoning Ordinance limits block length to 1,320 feet to allow for access to the common open space. The preliminary plat has the one Block arranged in Setbacks Front Side Rear Bluffline OHWM Required 35 feet 10 feet 50 feet 30 feet 100 feet Proposed 135 feet 1 10 feet 50 feet 30 feet I Not Available Blocks. The proposed single family lots are proposed to be platted as one Block. Section 20-6-7 of the Zoning Ordinance limits block length to 1,320 feet to allow for access to the common open space. The preliminary plat has the one Block arranged in segments of two to thirteen lots, thereby providing access to the open space areas between these segments. Although two of the proposed block "segments" are longer than 1,320 feet, staff advises that this is appropriate given the overall plat design and can be approved as a part of the PUD. Park and Trail Dedication. Section 21-7-18.H of the Subdivision Ordinance requires dedication of 10 percent of the area of the subject site (14.1 acres) for park development. The preliminary plat would propose to dedicate 18.5 gross acres (9.4 net acres) of land including the outlet and bluff area to the City to satisfy 66.7 percent of applicable park and trail dedication requirements. Access to the outlet area is provided via a connection to the internal public street. This land will be combined with land dedicated to the City as part of the adjacent Featherwind Farms development. The City intends to develop a greenway corridor along Northwest Creek from the Mississippi River southwest towards the west sanitary sewer service district. The outlet for Northwest Creek to the Mississippi River is located at the northwest corner of the subject site. The balance of the park and trail dedication requirement must be met as a cash fee in lieu of land calculated as follows: ($3,054 per lot * 33.3%) x 45 lots = $45,764.19 Landscape Plan. The applicant has submitted a landscape plan showing the addition of boulevard trees along the proposed east -west collector road and the addition of tree and shrub clusters within Outlots A and L to provide additional buffering along CSAH 39. The applicant shall submit additional information including tree and shrub species, the number of each species proposed as well as the proposed plant height at installation and at maturity. Easements. The preliminary plat illustrates drainage and utility easements around the perimeter of each lot as required by Section 21-7-15 of the Subdivision Ordinance. All easements are subject to the review and approval of the City Engineer. Grading and Drainage. The applicant has submitted grading, drainage and erosion control plans. These plans are subject to the review and approval of the City Engineer. Utilities. The single family lots are proposed to be served by on-site septic systems and wells. Provision of primary and secondary septic drainfield sites have been illustrated on the preliminary plat. Septic and well locations are subject to the review and approval of the City Engineer. Original Town Plat. A certificate of survey of the subject site identifies portions of the original Otsego town plat underlying the property. Established in the 1800s, the original town plat identifies lots, blocks and riqhts-of-wav that do not meet the City's current development regulations and are not considered to have development rights under the non -conforming lot provisions of the Zoning Ordinance. Platting the subject subdivision request requires vacation of the existing plat based on a finding that it serves no public purpose. 6 Attached Garage Area. The developer is also seeking an amendment of the Zoning Ordinance to allow larger attached garages. Section 20-16-4.13.4 of the Zoning Ordinance currently limits attached garages to 1,000 square feet. The developer is concerned that the current area limit does not allow sufficient depth for a four -stall garage to accommodate larger trucks or recreational vehicles/trailers. Given the larger home sizes that can be accommodated on R -C District lots (and other Zoning Districts requiring a minimum area of at least one acre) a larger attached garage can likely be accommodated. To this end, we have drafted the following language for the Planning Commission to consider. This language would allow for construction of a four -stall garage with a depth of 30 feet. 4. Attached accessory garages: a. The minimum floor area of an attached garage shall be 480 square feet. b. Within the A-1, A-2, R -C, R-1, R-2 and R-3 Districts, the maximum floor area of an attached garage shall be 1,200 square feet. C. Within the R -4A, R-4, R-5, R-6 or R-7 Districts, the maximum floor area of an attached garage shall be 1,000 square feet. d. The floor area of an attached garage shall not exceed that of the principal structure. RECOMMENDATION The proposed preliminary plat is consistent with the intent and provisions of the City's Comprehensive Plan and requirements of the R -C District. As such, we recommend approval of the Zoning Map amendments, variance and preliminary plat/PUD-CUP, subject to the following conditions. POSSIBLE ACTIONS Decision 1 — Zoning Map Amendment A.

Following the Planning Commission meeting, City staff forwarded the developer a letter extending the statutory review period to 30 June 2006 to ensure that adequate time is available to resolve the issues identified with this project. City staff and the developer met on 10 April 2006 and discussed the recommended conditions for approval of the project outlined in the Planning Report dated 29 March 2006. The developer has not made revisions to the submitted plans and intends to submit instead a response to City staffs comments for further discussion at the Planning Commission meeting on 17 April 2006. As no revisions have been made to the submitted plans, please reference the exhibits attached to the Planning Report of 29 March 2006. ANALYSIS Comprehensive Plan. The Future Land Use Plan guides the subject site for a mix of low to medium density and medium to high density residential uses that could result in as many as 1,731 dwelling units being developed within the subject site. The Future Land Use Plan is not an entitlement to development, however. The Comprehensive Plan states that in order to provide for proper growth management, provision of adequate services and prevent on over -allocation of any one type of land use, an interim land use allowing only A-1 District zoning and development densities is to be maintained as base entitlements for undeveloped properties. A decision to approve a rezoning of a undeveloped site to allow those uses guided by the Future Land Use plan and thus entitlements to development are to be evaluated based upon the policies of the Comprehensive Plan and conformance with applicable development regulations established by the Zoning Ordinance, Subdivision Ordinance and Engineering Manual. Even if processed as with a PUD, a proposed development plan must be consistent with at least the intent, if not the letter, of the City's development policies and regulations. The comments and conditions raised by City staff in response to the proposed development plans for Boulder Creek are intended to maintain consistency with the City's established development policies and regulations and equal treatment of similar projects approved under similar circumstances. These policies are significant as to the proposed balance of townhomes within this project and the sewer districts overall. The City's stated goal is that 70 percent of the total housing in the City is to be single family homes. Further, development in the sewer districts is also to be oriented primarily to single family homes. The current balance of housing preliminary platted within the sewer districts is 53 percent single family and 47 percent townhouse or multiple family dwellings. The proposed housing mix within Boulder Creek is 322 (48 percent) single family lots to 348 (52 percent) townhouse units. The proposed housing mix shifts the balance of housing overall within the sewer districts slightly to 52 percent single family and 47 percent townhouses or multiple family uses. We provide this information not to take issue with the proposed housing within Boulder Creek, but to head -off any suggestion that compliance with the City's established development policy regulations would justify increasing townhomes as a percentage of the housing developed on the subject site. School District Boundaries (Condition #4). The subject site is divided between the Elk River and St. Michael -Albertville School Districts along a line from the southeast corner of Pheasant Ridge south to CSAH 37 with school district boundaries going through single family lots, townhouse unit lots and townhouse base lots. Section 21-7- 4.M prohibits division of a single lot by a school district boundary. Wright County has stated that they object to the plat being approved having lots in two school districts and we concur with their position. The preliminary plat must be revised such that single family lot lines follow the school district boundary, townhouse buildings are located so as not to overlay the school district boundaries and townhouse base lots are divided into separate outlots at the school district boundary. CSAH 37 Right-of-Way/65 Foot Setback (Condition #5). The applicant has not submitted a revised preliminary plat to provide for 75 feet of right-of-way for the north half of CSAH 37 as required by Wright County. Likewise, the site plan has not been revised to provide the 65 foot setback from the minor arterial roadway as required by JCI:UUI I LV-VO-V.D. I of 11h e LUI IIr, g vl un in an wC. R.au icr, a is appncan. iS caSkiiig a c Planning Commission to consider a 25 foot reduction in the required setback based on the reasons outlined in their response to staff comments. We do not agree that the requested flexibility is appropriate under the proposed PUD -CUP for the following reasons: 1. Right-of-way needs for CSAH 37 are determined by Wright County and are required based on the Northeast Wright County Transportation Plan adopted in 2004 and is beyond the control of the City. 2. The intent of the 65 foot setback required by the Zoning Ordinance along arterial and major collector streets is to provide for maximum physical separation and area for vegetative buffering to minimize traffic impacts. The change in topography along the existing CSAH 37 corridor should be considered positive in addition to, not in lieu of the 65 foot setback. 3. The ultimate design of CSAH 37 will likely be a four lane roadway with space for dedicated left and right turn lanes along the corridor. Projected traffic volumes can be estimated to be 30,000 vehicles per day creating a need to create maximum separation and buffering of adjacent residential uses. 4. The topography changes between the proposed floor elevations of the townhomes along CSAH 37 and the existing roadway are directly related to the proposed grading plan which raises the elevation of the site along CSAH 37 to accommodate the proposed slab on grade dwellings. 5. Proposed retaining walls along CSAH 37 to achieve the proposed floor elevations of the adjacent dwelling units must be removed from the right-of-way and outlots to be deeded to the City. 6. The elevation changes between the edge of the proposed CSAH 37 right-of-way and the proposed floor elevations are only two feet to 13 feet above the north edge of the CSAH 37 right-of-way line making a blanket relief of the setback inconsistent with the reasons offered by the developer to justify the reduced setback. 7. Vegetation proposed along CSAH 37 is already required by Section 20-16-7.D of the Zoning Ordinance and does not exceed City requirements. 8. As future CSAH 37 has not yet been designed, assumptions about the final grade of the roadway cannot be made at this time. 9. The 150 foot wide right-of-way requirements for CSAH 37 apply from Queens Avenue east of TH 101 west to 1-94. Likewise the 65 foot setback applies over the entire corridor. Granting flexibility for Boulder Creek establishes precedence for reducing the setback in other locations. 10. Duerr Creek, Martin Farms, Zimmer Farms and Remington Coves have all complied with the right-of-way requirements and 65 foot setback along the CSAH 37 corridor. 11. Stonegate Estates, Prairie Creek, The Pointe, and Wildflower Meadow have also complied with the 65 foot setback requirement along a minor arterial roadway, although the right-of-way requirement was less for these projects based on date of approval or specific site location. 12. Prairie Creek, Pheasant Ridge, Crimson Ponds, Crimson Ponds West, Martin Farms and Arbor Creek all provided a 65 foot setback along major collector streets with anticipated lower traffic volumes. 13. The status of the exception parcels along CSAH 37 that were subdivided from al..... a site a relevant ♦o i4.c � application. Each f +has.- parcels LIIC subject SIIC IJ IIVI IGIGVAIIL W IIID present appii�+auvl I. �ai.ii vi uicoc Nui�.cio is an existing developed lot zoned A-1 District and entitled only to the uses allowed by that Zoning District. Any potential impact to the status of these properties as it relates to expansion of CSAH 37 is for Wright County to address. The preliminary plat must be revised to provide for the 75 feet of right-of-way for CSAH 37 and a 65 foot setback for dwellings adjacent to the roadway. Street F (Condition #6). City staff has requested that Street F, which currently dead - ends in a cul-de-sac be extended through to the west property line. A cul-de-sac at this location is not justified under Section 21-7-6.A of the Subdivision Ordinance as a through street is physically feasible. Further, extension of the street is necessary to allow for future development of adjacent unsubdivided parcels as required by Section 21-7-5.E of the Subdivision Ordinance and minimize unnecessary streets. Westerly Exception Access (Conditions #7 and #10). City staff requested that a public street with 50 foot right-of-way be provided from the intersection of Street A and Street O to the west line of the westerly most exception parcel. The developer has not revised the preliminary plat stating that grades in this area make this (and connection of DRWY 17 and DRWY-18) not feasible. Upon further review of the grading plan, it is the proposed grades that do not make the connection possible. Section 21-7-5.0 of the Subdivision Ordinance states that a developer cannot create undue hardship for the future development of adjacent undeveloped parcels, which the proposed grading plan clearly does. The preliminary plat and grading plan must be revised to provide for the public street from Street A and Street O to the west line of the westerly exception parcel. Street G (Condition #8). City staff has requested a street extension from Street G to the west plat line to provide inter -neighborhood access and circulation for adjacent undeveloped parcels as required by 21-7-5.E of the Subdivision Ordinance. The developer has agreed to provide this street. The preliminary plat must be revised to provide a public street from Street G to the west plat line not less than 50 feet from the south edge of Lefebvre Creek, subject to approval of the City Engineer. DRWY-3 (Condition #9). City staff recommended that DRWY-3 be revised to a 28 foot wide section based on eight units accessing directly to the driveway and six more units utilizing it for indirect access to Driveways 10 and 11. The City's policy has been that private drives providing access to more than four dwelling units be 28 feet wide. The City did provide an exception to this for the Wildflower Meadow preliminary plat allowing dead-end private drives between back-to-back townhome buildings to be 22 feet wide. The developer's response to the City staff comment is that DRWY-3 is not a primary through route, which is provided by DRWY-2 in this area. Given the number of dwelling units accessed directly or indirectly by DRWY-3, City staff stands by its recommendation for a 28 foot wide driveway design. DRWYs 24 and 26 (Condition #11). City staff has recommended that DRWY's 24 and 26 be extended to intersect Street D to eliminate long dead-end sections of the private driveway. The developer responds that not connecting DRWY's 24 and 26 to Street D minimizes poleriLial lllrough traffic. City staff ack—nowiedges that there are three other instances where the private driveways for the Hans Hagen units dead end. However, intersection spacing requirements are at least partially the reason for these designs. In that there is only one access to Units 206-255 (50 units), City staff stands by our recommendation that DRWY's 24 and 26 be extended to intersect Street D. Streets D and Q (Condition #12). City staff has recommended that Streets D and Q be revised based on the section having a 26 foot drive aisle and 9 foot parking bay on one side. The developer has not revised the preliminary plat to comply stating that they believe the site plan as presented meets City requirements. The reason for this change is to account for the loss of 284 potential guest parking stalls at the Hans Hagen townhomes which because of their site design do not have a driveway apron typical of most townhome site designs. The driveway apron provides space for two off-street parking stalls in addition to the two stalls required in a garage and the one-half stall of guest parking. Without providing the bump -out on -street stalls on Streets D and Q, the site plan creates unnecessary risk for congestion in the public streets. Streets J and S. City staff had previously recommended that Streets J and S be revised to meet the 250 foot centerline radius requirement of Section 21-7-7.G of the Subdivision Ordinance. Upon further review, the City Engineer is satisfied that the design of Streets J and S are based upon existing physical conditions and the design of the streets is acceptable. Single Family Setbacks (Condition #14). The preliminary plat illustrates proposed front yard setbacks to local streets less than required by the R-5 District. The City has allowed such reductions in the past based on unique site designs (Pheasant Ridge and Remington Coves) or superior housing design. City staff is supportive of the reduced setbacks for the proposed alley accessed lots given their unique configuration. City staff has requested typical house plans to be developed within the proposed preliminary plat to justify the proposed reduction consistent with past City actions. This information has not been provided. The 35 foot front yard setback (also applied to the side yard of a corner lot abutting a public street) is an established community standard and a characteristic of existing neighborhoods. Deviation from this standard without appropriate justification would compromise the intent of the provision and undermine its consistent application. Townhouse Setbacks (Condition #15). The developer has suggested providing a 23 foot setback from a private drive by reducing the design width of the 24 and 28 foot wide private drives two feet. The City agreed to allowing 22 foot wide private drives for Wildflower Meadows for the dead-end stubs between buildings. City staff would support a similar design here. The 28 foot section is required on more significant circulation and access routes and we do not support the requested two foot reduction. Any revisions to the private drives must be subject to further review by City staff. Revised Townhouse Building Plans (Condition #16). The developer showed illustrations of revised exteriors for the Sharper and Novak -Fleck townhomes at the Planning Commission meeting on 3 April 2006. The developer has not followed through with City staff's request for building plan elevations to be submitted to determine if the changes meet the intent of our initial comments. These plans must still be submitted. The developer also does not agree with City staff's comment that a patio area should be provided for as part of the site plan for the Sharper and Novak -Fleck townhomes. Given the pedestrian oriented amenities of the project, the opportunity for outdoor recreation by residents would seem to be a logical request given that there is adequate space on the site plan in most areas. We would suggest that the patio at least be made a buyer's option. Grading Plan (Condition #20). The City Engineer remains concerned about the proposed grade change at the temporary dead -ends of Streets L and N. The proposed grades are approximately five to 10 feet higher than that of the adjacent undeveloped parcel to accommodate walkout building plans. Without the consent of the adjacent property owner to match these proposed grades when their property develops, the grading plan must be revised to better tie into the existing grades of the adjacent property so as not to cause a hardship for that property in developing in accordance with Section 21-7-5.0 of the Subdivision Ordinance. Phasing Plan (Condition #23). At our meeting on 10 April 2006, the developer indicated that a phasing plan outlining development of 130 to 140 dwelling units per year had been prepared. The phasing plan has not been submitted however. City staff would recommend a condition stating not more than 140 dwelling units shall be final platted each calendar year unless approved by the City Council. If less than 140 dwelling units are final platted in any given year, those dwelling units would be allowed to be rolled ahead to future years. This approach should provide the City sufficient confidence in the staging of the project while allowing the builders flexibility to match product to current market conditions. CSAH 37 / Quaday Avenue (New Condition #24). Wright County responded to the project EAW that the proposed development would cause the need for a traffic signal to be constructed at Quaday Avenue and CSAH 37. As this is a capital expense the City has not planned for and is directly related to traffic generated by the project, the cost of this signal will be the developer's responsibility. The City may agree as part of the development contract to obtain funds from other benefiting properties at such time as they develop to partially refund the cost of the improvement. This issue is subject to further review by the City Engineer. RECOMMENDATION The developer has submitted responses to the comments and recommended changes to the preliminary plat offered by City staff. From our meeting with the developer on 10 April 2006 and further review of their comments, we disagree with both the basis and conclusions of the responses. We continue to recommend significant and numerous modifications to the preliminary plat prior to Planning Commission action and thus suggest tabling the requests again. Although it is preferred that the City always act in the affirmative with regards to development requests even with many conditions, if the developer indicates a continued unwillingness to revise the preliminary plat as set forth by City staff, findings for denial have been provided. If the Planning Commission moves to deny the requested Zoning Map amendments, no action is required on the preliminary plat. 0 POSSIBLE /ACTIONS Decision 1 - Zoning Map Amendment A. Motion to approve a Zoning Map amendment rezoning the subject site from A-1 District to R-6 District and R-7 District based on a finding that the action is consistent with the Comprehensive Plan. B. Motion to deny the application based on a finding that the request is inconsistent with the following provisions of the Comprehensive Plan, Zoning Ordinance and Subdivision Ordinance: ■ The preliminary plat is premature under the Comprehensive Plan as it inconsistent with the City's interim land use plan goals to avoid over -allocation of any one -type of land use (townhouses) and does not meet the City's goals for increasing single family homes as the predominate housing type available within the sanitary sewer service districts. ■ The preliminary plat does not provide right-of-way for CSAH 37 as required by the NEWC Transportation Plan. Until this right-of-way can be acquired, the proposed preliminary plat is premature in accordance with Section 21-4-2.0 of the Subdivision Ordinance. ■ Wright County will require the City to provide for installation of a traffic signal at CSAH 37 and Quaday Avenue as a result of the proposed development. This is a capital expense not planned or budgeted for by the City making the proposed development premature in accordance with Section 21-4-2.0 of the Subdivision Ordinance. ■ The preliminary plat does not conform to the 65 foot setback required from minor arterial streets by Section 20-68-6.113.1 of the Zoning Ordinance. ■ The preliminary plat includes single family lots, townhouse unit lots and townhouse base lots that are divided by established school district boundaries prohibited by Section 21-7-4.1M of the Subdivision Ordinance. ■ Street F as shown on the preliminary plat terminates in a permanent cul-de- sac when extension of a through street to the west property line is physically feasible and required by Section 21-7-6.A of the Subdivision Ordinance. ■ Not extending Street F to the west plat line may create a hardship for future development of adjacent unsubdivided parcels as prohibited by Section 21-7- 5.E of the Subdivision Ordinance. ■ The preliminary plat does not provide for extension of a public street from Street G to the west plat line to provide inter -neighborhood access and circulation for adjacent undeveloped parcels as required by 21-7-5.E of the Subdivision Ordinance. ■ Lots 501 to 505 and Lots 580 to 586 have double frontage to local streets where such lots are prohibited by Section 21-7-4.N of the Subdivision Ordinance unless it is demonstrated that double frontage iots are the only reasonable alternative for development. The developer has not demonstrated that the double frontage lots are the only reasonable alternative. VA ■ The minimum lot area and width requirements shown on the preliminary plat for single family lots are less than required by Section 20-66-6.A of the Zoning Ordinance for the R-5 District. ■ The front yard and side yard setbacks abutting a street of a corner lot for the proposed single family lots shown on the preliminary plat are less than required by Section 20-66-6.0 of the Zoning Ordinance for the R-5 District. ■ The front yard setback for townhouse units shown on the preliminary plat is less than that required by Sections 20-67-6.B.1 and 20-68-6.B.1 of the Zoning Ordinance for the R-6 District and R-7 Districts respectively. ■ The preliminary plat does not provide public street access to PID 118-500- 273405 as required by Section 21-7-5.0 of the Subdivision Ordinance because of the elevation changes to existing grades proposed by the developer's grading plan. ■ The submitted grading plan does not provide for a property transition to adjacent undeveloped parcels at Streets L and N as required by Section 21-7- 5.0 of the Subdivision Ordinance as the proposed grade elevations are significantly higher than the existing grades on the adjacent property to accommodate proposed walk -out home designs. ■ The preliminary plat does not address the need for additional dedicated on - street parking along Streets D and Q due to the lack of garage apron parking for the Hans Hagen Townhome units that would cause increased congestion in the public street. C. Motion to table. Decision 2 — PUD-CUP/Preliminary Plat A. Motion to approve a PUD-CUP/Preliminary Plat for Boulder Creek, subject to the following conditions: Approval of the preliminary plat shall not guarantee access to sanitary sewer service.

We offer the following comments for your consideration. Description (Item No. 6d) This item states that Boulder Creek Development has no plans for additional phases of this project. We note, however, that the wetland delineations for this project included parcels immediately to the south and east of the parcel. Additionally, the plat book shows ownership by the same company. Item No. 29, Cumulative Impacts, states, "It is reasonable to expect that surrounding properties will be developed for residential use in the future." We recommend that the project proposer clarify their plans for those parcels and consider how their development may affect common resources. For example, there may be better wetland replacement opportunities on the parcel to the south. Cover Types (Item No. 10) The table in Item No. 10 shows the conversion of 11.2 acres of wooded/forest cover. Depending on the condition of this wood, the project proposer may elect to market it A& sawlog, landscaping material, firewood, or bio -fuel for the production of energy. We strongly recommend that the City contact Jean Mouelle, Regional Forest Utilization and Marketing Specialist (651772-7567), for advice on this subject. Additionally, the removal of this amount of forest during the migratory bird nesting season may result at a' L ,7 T. .� l :�»... �...... 1..:...7 j-11- -f ....s and lTR may be in -1 ie destnictlon of active ulru nests. . akd gS LS rn.b. aLw L't..tJ, 1:.. :b s a: ebbs, i:i' j vv subject to provisions of the federal Migratory Bird Treaty Acct. The bird nesting season typically extends from mid-April through mid-August, with a peak from mid-May through mid-July. We recommend that site clearing occur either before or after the bird nesting season.

Wildlife and Ecologically Sensitive Resources (Item No. 11 According to part A of this item, the project proposer intends to avoid impacts to wetlands and wooded 4reas to the extent possible. Part B indicates that potential impacts to loggerhead shrikes will be minimized by preserving grassy open areas with scattered trees and shrubs. Item No. 10, however, shows the loss of 127.2 acres (83%) of wooded, grassy and brushy habitat. It also shows plans to preserve 16.6% of the total parcel acreage as open space in the form of wetlands, ponds, creeks, forests and brush and grasslands. Rather than retaining more area in open space, we recommend that open grassy areas, including stormwater pond and creek buffers and especially undeveloped areas near Quaday Avenue be enhanced to restore additional shrike habitat. This can be accomplished by planting native tallgrass prairie grasses and adding scattered plantings of red cedars, wild plums and flowering crab trees. Vehicle -Related Air Emissions (Item No. 22) This item has not been adequately addressed. According to Item No. 21, the project will include the addition of 1,318 new parking spaces. The federal guidelines referred to in the response are not relevant. The directions to Item No. 22 state that if the project involves 500 or more parking spaces, the RGU should consult the EAW Guidelines to see how to proceed. Thank you for the opportunity to review this project and the EAW. We look forward to receiving your record of decision at the conclusion of environmental review. If you have any questions about these comments, please contact staff ecologist Michael North at 218-833-8726.

A 25' building setbacks along alleys, local, and collector streets is proposed. A minimum of 35' is required. 2. Wright County requires 75' of R.O.W. along C.S.A.H.37. The minimum building setback for lots along county roads is 65' from the R.OW. This will require extensive reorganizing of the lots along the county road. 3. Alleys are proposed along the rear lot lines of many of the single-family lots. A setback of 23' is proposed along the alleys. City zoning ordinance does not permit alleys within residential areas. (21-7-8.E) City standard required minimum setback is 35'. �. 4. The minimum side yard setback required is 10'. (20-67-6.B) 5. The double frontage lots between Streets A & E and Streets G & H are not allowed. The street and lot configuration for these areas shall be revised. EXISTING CONDITIONS 1. Provide all utility information (size, type, invert elevations, etc.) for all utilities within 150' of the boundary line. (i.e. intersection of Quaker Avenue NE and Quaday Avenue NE and the south & east plat lines of Pheasant Ridge 801 Addition). TRAFFIC/ACCESS ISSUE 1. Access to the plat is being provided off of C.S.A.H. 37, Quaday Avenue NE, 78th Street NE, and 76th Street NE. 2. Streets A & B have center medians proposed. They are not per city standards and will require city approval. 3. Alleys are proposed to serve as access to the single-family lots between Streets C & B, and Streets A & M. Alleys are prohibited in residential areas. (21-7-8.E) PRELIMINARY PLAT 1. Outlots A, B, and C have existing drainage and utility easements over them.

Street "S" is shown with only 50' of ROW, please revise. 3. Street "S" shall be realigned to provide a minimum 250' radius for the horizontal curves. This may require redesigning the current layout of the lots surrounding the street to provide proper access to the exception. 4. All sidewalks and bike paths shall be covered by a permanent easement. 5. The R.O.W. along C.S.A.H. 37 is subject to county approval. 6. A 25' building setbacks along alleys, local, and collector streets is proposed. A minimum of 35' is required. 7. Streets shall be named in accordance to the Wright County grid naming system. 8.

Lefebvre Creek shall be covered by a 100' easement centered on the creek or an easement to the 100 -year HWL, which ever is greater. 11. A street connection shall be made to the property to the west of Street G and south of Lefebvre Creek. This was a requirement during the concept plan review. 12. Mitigated wetland areas need to be shown on the plat. (north half of Outlot G) PRELIMINARY SITE PLAN Sidewalk shall be extended to the cul-de-sac at the north end of Street F. 2. A temporary cul-de-sac is required at the west end of Street O. 3. A street connection to the property west of lots 534-536 shall be made. This was a requirement during the concept plan review. 4. The sidewalk along Street G shall be switched to the opposite site of the road to limit the number of street crossings. \\Ha01\Shared Docs\Municipal\Aotsego22xx\2281\ot2281-RVW2.doc PRELIMINARY UTILITY PLAN SANITARY SEWER SYSTEM 1. All sanitary sewer pipes shall be placed at appropriate grades so as not to exceed a flow velocity of 15 fps. It appears that drop structures will be required for the sanitary sewer along Street `B" and Street "K'. 2. The connection to the existing sanitary sewer manhole at the intersection of Street "B" and Quaday Avenue shall be made within 2' of the existing downstream invert to avoid the need of drop manhole at the connection. This will require the invert of the upstream manhole to be lowered. 3. The detail for the multi -family area (row townhome neighborhood) depicts 4' horizontal separation between the storm sewer and sanitary sewer under the driveways. A minimum of 10' of horizontal separation is required. 4. The sanitary sewer shall be stubbed to the west under the required street connection to serve the property west of Street G and south of Lefebvre Creek. 5. An existing 70'-8" SDR 26 PVC stub with an invert elevation of 848.78 has been provided out of the existing sanitary sewer manhole at the intersection of Street A and 78a' Street. This stub shall be used to avoid the need for boring and jacking under 78`h Street to make a connection. WATER DISTRIBUTION SYSTEM 1. Hydrant coverage is insufficient. Maximum hydrant spacing shall be 300' (150' radius) for commercial, industrial, or multi -family residential areas and 500' (250' radius) for single family residential areas. 2. The method of connecting to the existing watermain shall be called out. A wet tap connection shall be made if a connection is made where there is no stub provided. 3. Additional valves are required at many watermain tee and cross locations throughout the project. 4. The watermain serving the multi -family homes in the southwest corner of the development shall be looped. 5. The 12" DIP watermain at the south end of Street A shall be connected to the west property line just north of C.S.A.H1. 37. 6. The geotechnical report identifies a ground water elevation in the range of 868- 871. Plugs are required on all hydrants below the ground water elevation. \\Ha01\Shared Docs\Municipal\Aotsego22xx\2281\ot2281-RVW2.doc STORM SEWER SYSTEM 1. The NWL, 2 -Year, 10 -Year, and 100 -Year HWL shall be shown for all proposed and existing sedimentation ponds, wetlands, and Lefebvre Creek. 2. A drainage and utility easement will be required over all the treatment ponds, storm sewer outside of ROW, wetlands, and drainage swales. 3. The location of the low point and the catch basins along Street 33 do not agree. STREETS Any alleys permitted shall have a right-of-way width of at least 24'. (21-7-8.13) 2. The street intersections shall be rounded by a radius of no less than 20 feet. Radii to arterial and collector streets shall be no less than 30 feet and 50 feet for all streets to C.S.A.H. 37. 3. A temporary cul-de-sac is required on the west end of Street O. All temporary cul-de-sacs shall be covered by a temporary easement. Please submit the easement documents to be filed with the Final Plat. 4. The cul-de-sac at the end of Street F will need to have tip out curb around the center island. A 20' wide lane is required around this center island. 5. It appears that cross gutters will be required at many of the private drive intersections. Provide intersection details and/or spot elevations to depict the intended direction of street runoff at the intersections. Intersections with grades of less than 1.0% over bituminous surfaces will require cross gutters. 6. A street connection is required to the property west of Lots 534-536. This was a requirement during the concept plan review. 7. B618 curb and gutter is required for all multi -family areas and along all single- family lots being served by alleys. DETAILS Street sections have been selected based on a geotechnical engineer recommended R -value of 50. Though all street section details agree with the City of Otsego's typical section used for a 9 Ton residential street, it is unclear which street section is to be used for which street. Please clarify. 2. The house grading elevation "key" detail shall call out a lowest opening elevation. MaMShared Docs\Municipal\Aotsego22xx\2281\ot2281-RVW2.doc 3. The setbacks called out in the individual details for each type of building do not agree with the setbacks on plans, City Standards, or the preliminary plat. PRELIMINARY GRADING PLAN 1. The NWL, 2 -Year, 10 -Year, and 100 -Year HWL shall be shown for all sedimentation basins. 2. The soil borings shall be shown on the plan. (21-6-2.B.8.) 3. Some of the spot elevations depict a crown in the private streets and driveways and others indicate a cross slope. Please clarify. 4. A minimum 1.5' of freeboard is required from all calculated 100 -year HWL's or emergency overflows for non -calculated areas. 5. Please depict all easements and setbacks for ponds, wetlands, and Lefebvre Creek. 6. For Street L and Street N, the difference in elevation at the east end of the road and the existing ground elevation just offsite is approximately 10'. This appears to be strictly done for the type of building pad (walkout). Making a future connection to Street L and Street N to require an extensive fill on the adjacent property as well as at the eastern end lots of Street L and Street N within Boulder Creek. Please revise to more closely match the existing offsite ground. 7. Permission from the adjacent property owner is required to extend any grading onto the adjacent property at the north end of Street Q. SURFACE WATER MANAGEMENT There is a low area to the west of Lot 533 that currently has a natural overland outlet to the creek that will be cut off by this development. An outlet for this low area shall be provided. 2. The 100 -year HWL of the ponds and wetland along the creek shall be no less than the 100 -year HWL of the creek. 3. The hydrology and storm sewer design is still under review. WETLANDS 1. Wright Soil and Water Conservation District, has identified more wetland area and requests that these wetlands be mapped. 2.
