STAFF REPORT DATE: 8/12/2019 REGULAR ITEM #: Unfinished Business TO: Planning Commission FROM: Ken Roberts, Planning Director AGENDA ITEM: Conditional Use Permit – Carmelite Hermitage of the Blessed Virgin Mary REVIEWED BY: Ben Prchal, City Planner BACKGROUND: The City has received an application for a conditional use permit (CUP) to allow the construction of a place of worship (chapel) on the property of the Carmelite Hermitage at 8249 Demontreville Trail. This site within a Public and Quasi-Public Open Space zoning district. Places of worship (such as churches and chapels) are conditional uses in the Public and Quasi-Public Open Space zoning district. On June 24, 2019, the Planning Commission held a public hearing about this request. The Commission reviewed the staff report and took testimony from several persons (for and against) the CUP for the chapel. The Planning Commission closed the public hearing for the CUP and took no action on the proposal to allow the applicant and the City to review the question and alternatives about access and direct access for the proposed chapel. ISSUE(S) BEFORE PLANNING COMMISSION: The Planning Commission is being asked to consider the request for the conditional use permit and the variance request about direct access and then make a recommendation to the City Council about these requests for the proposed chapel at the Carmelite Hermitage at 8249 Demontreville Trail. PROPOSAL DETAILS/ANALYSIS: Applicants: Carmelite Hermitage of the Blessed Virgin Mary, 8249 Demontreville Trail, Lake Elmo, MN 55042 Property Owners: Discalced Carmelite Nuns of St. Paul, 8251 Demontreville Trail, Lake Elmo, MN 55042 Location: ALL OF GOVERNMENT LOT 4, IN SECTION 9, TOWNSHIP 29 NORTH, RANGE 21 WEST, ACCORDING TO THE GOVERNMENT SURVEY CONTAINING 59.4 ACRES OF LAND. ALSO, THE SOUTH 30.6 ACRES Page 2 OF GOVERNMENT LOT 4 IN SECTION 4, AND THE SOUTHWEST QUARTER OF THE SOUTHEAST QUARTER OF SAID SECTION 4, ALL IN TOWNSHIP 029 RANGE 021, ACCORDING THE GOVERNMENT SURVEY, BEING THE SOUTH 688 FEET THEREOF. PID# 09.029.21.12.0002 Request: Conditional Use Permit for a place of worship and religious institution Existing Land Use: Hermitage – A retreat for monks with a community building and garage, cloistered living area with courtyards Existing Zoning: PF – Public and Quasi-Public Open Space Surrounding Land Use / Zoning: North – Properties owned by Discalced Carmelite Nuns (8251 Demontreville Trail) and Jesuit Retreat House (8243 Demontreville Trail); South – Single-family homes (Rural Residential); East – Single-family homes (Rural Residential); West – Lake Demontreville Comprehensive Plan Guidance: 2030 – Public/Park 2040 – Institutional. As noted the in the 2040 Comprehensive Plan, this land use category identifies land that is used for schools, religious institutions, City Hall, municipal buildings, libraries and other institutional uses. History: In December 1991, the City approved a variance (regarding code requirement for having frontage on a public road) and a master plan for the Carmelite Hermitage of the Blessed Virgin Mary. This master plan included a phasing plan showing four parts or phases and included a court, guest house /library, chapel, cloister, hermitage, community building and workshop. The variance noted that the applicant has a private recorded easement that allows access to the north from their site to Demontreville Trail North (across the adjoining properties). In October 2007, the City approved an amendment to the approved master plan to allow an additional accessory building (1,512 square feet) on their site. Deadline(s) for Action: Application Complete – 5-24-2019 60 Day Deadline – 7-23-2019 Extension Letter Mailed – No 120 Day Deadline – N/A Applicable Regulations: §154.210 – Off-Street Parking Article XIV: Public and Semi-Public Districts Request. A place of worship in Lake Elmo is a conditional use in the Public and Quasi-Public Open Space district. The City approved the Master Plan for the Carmelite Hermitage in 1991 as previously mentioned in this report, but a conditional use permit was never obtained, as the use was considered permitted at that Page 3 time. The City adopted the Public and Quasi-Public Open Space ordinance in September of 2000, and this ordinance required conditional use permits for places of worship and set forth certain standards for such a use as well as other district requirements that are in place today. Because the property does not have a conditional use permit as is required by the Zoning Code, the existing use is considered legal non-conforming. The City’s ordinance states that the lawful use of a building or structure may continue, but that the continuation of the non-conforming use does not include expansion. Since the applicant is requesting expansion of the non-conforming use (by adding a chapel), the City must approve a conditional use permit for the entire property in order for the applicant to add the chapel and to bring the property in to compliance with current zoning requirements. (Note: Conditional use permits run with or are applicable to a specific property, not with a particular owner or person). Use on Proposed Site. The proposed chapel would be to the west of the existing buildings and south of the existing driveway into the site. As shown on the plans, the chapel would be about 8,520 square feet in area with a height of 41 feet, four inches. The applicant noted in their project description that the chapel would be used for liturgical services and for personal prayer and would have seating for 42 guests in addition to the seating for the 12 members of their community. They also state that since their community members live in a Hermitage and since their way of life is relatively secluded, they do not generate a significant amount of vehicle traffic. They are anticipating an average of 10-15 visitors a day to their site. They have two part-time employees to help maintain the grounds and buildings. The Hermitage is open to the public between 7:30 AM and 4:30 PM. They are not planning to hold regular church or public worship services in the chapel. Setback and Impervious Surface Requirements. The following table outlines how the proposed use adheres to the setback and impervious surface requirements of the Public and Quasi-Public Open Space District. Public and Quasi Public Open Space Zoning Standards Standard Required Proposed Maximum Parcel Area 20 acres 90 acres Lot Width – Minimum (at ROW) 100 feet Approximately 1793 feet Lot Depth – Minimum 150 feet Approximately 2015 feet Maximum Height 50 feet Approximately 41 feet Maximum Impervious Coverage 15% 1.2% Front Yard Setback – Building 100 feet Approximately 1000 feet Interior Side Yard Setback – Building 100 feet Approximately 900 feet Rear Yard Setback - Building 100 feet Approximately 1000 feet Parking Lot Setback 100 foot Approximately 200 feet Standards for Places of Worship within the Public and Quasi-Public Zoning District. The following outlines standards for places of worship as outlined in the Public and Quasi-Public zoning district. a. Direct access is provided to a public street classified by the Comprehensive Plan as major collector or arterial; • Staff Comment. The City approved a variance for the access to this site in 1991. There is an existing driveway that connects the property to Demontreville Trail that is in an access easement that has been in place since 1904. The City has classified Demontreville Trail as a major collector street. Page 4 b. No use may exceed 235 gallons wastewater generation per day per net acre of land; • Staff Comment. It is unknown how much wastewater is generated, but it is assumed there is no more than 235 gallons being generated per net acre on a 90 acre site. c. No on-site sewer system shall be designed to handle more than 5,000 gallons per day; • Staff Comment. The proposed drainfield is 15,000 square feet in area and according to the SSTS design report dated May 8, 2019 is designed to handle 350 gallons of waste a day. d. Exterior athletic fields shall not include spectator seating, public address facilities or lighting; • Staff Comment. There are no exterior athletic fields. e. No freestanding broadcast or telecast antennas are permitted. No broadcast dish or antenna shall extend more than 6 feet above or beyond the principal structure. • Staff Comment. There are no broadcast or telecast antennas, existing or proposed. Parking Lot Requirements. The project plans show a new 18-vehicle parking lot to the west of the entrance driveway and to the northwest of the proposed chapel. Maneuvering Area. There is sufficient space in and around the parking lot so vehicles do not need to back in to the public street. Surfacing and Drainage. The majority of the parking lot would have curbing and would be paved with a durable surface. Stormwater drainage would be directed to the northeast to a new infiltration basin on the site. Marking of Parking Spaces. The Code requires parking areas with five or more spaces to be marked with painted lines at least four inches wide. The plans for the parking lot show striping to meet this requirement. Curbing. Open off-street parking areas designed to have head-in parking along the property line shall provide a bumper curb or barrier of normal height. The proposed parking lot meets this requirement. Accessible Parking. The proposed number of parking spaces is 18 and of these, one would be handicap –accessible, which meets the Americans with Disabilities Act (ADA) requirements. Number of Parking Spaces. The City’s parking requirements requires one space per six seats. There are 54 seats within the chapel so the Code would only require 9 parking spaces for the chapel. The applicant has proposed 18 parking spaces thus meeting this requirement. Parking Lot Landscaping and Screening Standards Perimeter Parking Lot Landscaping. The proposed parking lot is located in the center of the property – well away from the street right-of-way and from any property lines. The existing trees on the site provide adequate screening and landscaping around the proposed parking lot. Landscape Plans. The applicant has submitted surveys and project plans showing the existing landscaping and wooded areas on the property. Since the site has extensive areas of trees and the since the proposed chapel would not be removing any existing trees, staff does not recommend that the City review or require additional landscaping on the property. Page 5 Septic Drainfield. The existing drainfield is to the south of the existing building and the proposed chapel will not affect the existing drainfield. The project plans show a new drainfield to the south of the proposed chapel. This new drainfield will require a permit from the Washington County Public Health and Environment Department before installation. Architectural Standards within the Public and Quasi-Public Open Space. The exterior design of the chapel is subject to the Performance Standards set forth in Section 154.600(F) of the Zoning Code. The proposed chapel would be constructed with a mix of brick, limestone, marble and have a green shingled roof. These materials meet the requirements for exterior materials as listed in the zoning code and the overall design meets or exceeds all the design standards set in Section 156.600 of the Zoning Code. Fire Chief Review. I have attached the Fire Chief’s review comments (dated June 5, 2019) for your consideration. Staff is recommending that the applicant meet all the requirements of the Fire Chief before the City issues a building permit for the chapel. City Engineer Review. The City Engineer’s review memo (dated June 17, 2019) is attached to this report. His comments are primarily about stormwater management for the project. He noted: • The project will require a Valley Branch Watershed District (VBWD). • The storm water facilities for this development should remain privately owned and maintained. • The storm water facility 100-year HWL must be fully contained within the subject property and easement must be provided to protect the 100-year HWL flood area. • The applicant shall provide drainage and utility easement over storm water BMP including the 100- year HWL and pond maintenance access road and access bench. Recommendation Findings. Staff recommends the following findings: 1. The proposed use will not be detrimental to or endanger the public health, safety, comfort, convenience or general welfare of the neighborhood or the city.

The proposed use will not result in the destruction, loss or damage of a natural or scenic feature of major importance. N/A Recommended Conditions of Approval. If the Planning Commission wishes to recommend approval, staff recommends the following conditions: 1) The applicant must obtain all other necessary City, State, and other governing body permits and approvals before the commencement of any construction activity on the site. These include, but not limited to, a Valley Branch Watershed District permit, approval of revised plans by the City Engineer, a building permit and an on-site wastewater (septic) permit. 2) All items and changes outlined by the City Engineer in the memorandum addressing the Carmelite Chapel Conditional Use Permit and Site Improvements dated June 17, 2019 shall be incorporated into the project plans. 3) All items outlined by the Fire Chief in his memo dated June 5, 2019, shall be incorporated into the project plans and before the City issues a building permit for the project. Page 7 4) The applicant must provide written documentation demonstrating adequate wastewater management facilities exist or are proposed to serve the proposed chapel. This should include either a Washington County inspection compliance report for the existing on-site wastewater system or a wastewater management plan and permit approved by Washington County to serve the proposed chapel. 5) The applicant or owner receive a building permit from the City for chapel within 12 months of City Council approval of the conditional use permit. 6) If the applicant or owner has not taken action toward starting the chapel or if substantial construction of the chapel has not taken place within 12 months of the City’s approval of conditional use permit, the CUP approval shall become void. The applicant or owner may request City Council approval of a time extension to start or implement the conditional use permit. FISCAL IMPACT: None OPTIONS: The Planning Commission may: • Recommend approval of the Conditional Use Permit with recommended findings and conditions of approval. • Recommend approval of the Conditional Use Permit with amended findings and conditions of approval. • Recommend denial of the Conditional Use Permit, citing findings for denial. RECOMMENDATION: Staff is recommending approval of the Conditional Use Permit for the Carmelite Hermitage of the Blessed Virgin Mary including the proposed chapel for the property located 8249 Demontreville Road: “Move to recommend approval of the conditional use permit for the Carmelite Hermitage including the proposed chapel for the property located at 8249 Demontreville Road with recommended findings and conditions of approval as drafted by Staff.” ATTACHMENTS: • Application Narrative dated May 24, 2019 • 4 City Maps • Site Survey • Certificate of Survey • Engineering Project Plans (2 sheets) • Architectural Plans (5 sheets) • May 8, 2019 SSTS Design Report • City Engineer Review Memo dated June 17, 2019 • Fire Chief Review memo dated June 5, 2019 • Neighbor comments (Falzone) dated June 16, 2019 1 Land Use Application – 5-24- 2019 Property Location All of Government Lot 4 in Section 9, Township 29 north, Range 21 west, City of Lake Elmo, Washing- ton County, Minnesota, according to government survey containing 59.4 acres of land. Also the south 30.6 acres of Government Lot 4 in Section 4, and of the southwest quarter of the southeast quarter of said Section 4, all in Township 29 north, Range 21 west, according to government survey, being the south 688 feet thereof. Detailed Reason for the Request In December of 1991, the City of Lake Elmo approved the master plan of the Carmelite Hermitage of the Blessed Virgin Mary (aka Carmel of the Blessed Virgin Mary). The master plan included a phasing plan of four parts. Phase 1, consisting of a community building and garage was constructed in 1991/92. Phase 2, consisting of a central court yard with covered walkways (cloister) was constructed in 2001/2002. Phase 3 consists of a chapel and is the building we would now like to construct. Phase 4 will consist of a guest building and library. We hope to commence Phase 4 around 2022. We request City approval of a conditional use permit to construct our chapel because it is an essential building of every monastery and will provide needed worship space for the members of the Hermitage and their guests.

History of the Property The property under consideration was homesteaded in the 1800s and remained farm land until 1954. At one time William Jennings was owner of all of Lot 4, Section 9, Township 29, Range 21, and all of Lots 3 and 4 and the West one-half of the Southeast Quarter of Section 4, Township 29, Range 21, West in Washington County, Minnesota. On 25 August 1904, William Jennings and his wife conveyed to Christian Figge by warranty deed dated that day, Government Lot 4, Section 9, Township 29, Range 21, and also the South 30.6 acres of Lot 4 in Section 4 and of the Southwest Quarter of the Southeast Quarter of Section 4, Township 29, Range 21. As part of said conveyance, William Jennings also granted to Christian Figge a right of way (easement) to Figge’s property over Government Lots 3 and 4 in Section 4 as described in a deed rec- orded in Book 72 of the Book of Deeds, page 80, Washington County, Minnesota. This is the easement from Demontreville Trail across property now owned by the Jesuit Retreat House and to the property un- der consideration that has existed since 1904. In 1954, the Discalced Carmelite Nuns of Saint Paul, a non-profit corporation under the laws of the State of Minnesota, were looking for property upon which to build a permanent monastery. They were advised of the property which they now own and entered into negotiations with the current owners. On 2 February 1954, Phillip C. Mackey and his wife Bernadine R. Mackey conveyed their property, along with its easement, to the Discalced Carmelite Nuns of Saint Paul by warranty deed, dated that day, and filed for record in Washington County, Minnesota, on 4 February 1954. At the time of purchase, said property had been on the market for five years. The Carmelite Nuns built their monastery upon their newly acquired property in 1954/55. They moved into the new monastery in 1955 and have resided there since that time. In 1983, Rev. John Burns, a Carmelite priest, became chaplain for the Carmelite Nuns in Lake Elmo. After several years, the Carmelite Nuns and Fr. Burns mutually agreed that it would be beneficial to the Carmelite nuns if the Carmelite Fathers and Brothers established their own monastery on the property. This would assure the nuns of future chaplains and allowed the Carmelite Fathers to have a presence in the Twin Cities. In 1987 Carmel of the Blessed Virgin Mary (aka Carmelite Hermitage, Carmelite Her- mitage of the Blessed Virgin Mary) was incorporated in the State of Minnesota. Other priests and brothers joined the community over the years. The Order of Carmelites was founded on Mount Carmel (present State of Israel) sometime before 1200 AD. From there it has spread to six continents. Currently there are about 900 monasteries of nuns with a total membership of 10,000, and 1,000 houses of Carmelite priests and brothers with about a total mem- bership of 6,000. We are part of the Roman Catholic Church. Our way of life consists of prayer, study, and labor to support ourselves. We also welcome visitors who wish to find a quiet place to refresh their minds and hearts, to reflect and pray, either by themselves or with us, and who may desire to seek guidance for their lives by talking with one of the members of our community. The chapel is the heart of our monastery buildings. Our day is punctuated by liturgical ser- vices and times of personal prayer. We live a simple way of life and support ourselves through arts and crafts, organic gardening, maple syrup production, woodworking and self-maintenance of our property and buildings. 2d, i. The 90 acre tract upon which the new chapel will be built is approximately 60% woodland and 40% prai- rie and is situated on the east bank of Lake Demontreville. Wildlife is abundant in all areas of the prop- erty. We have a personal commitment to live in harmony with our natural surroundings and to employ horticultural practices which do not pollute but rather benefit the environment. We have spent many hours removing buckthorn and diseased trees from our property and planting species of trees and shrubs which are beneficial to wildlife. 4 The new chapel will be situated just west of the existing buildings of the Hermitage. The land there is almost flat, and construction of the chapel will not require any significant changes to the topography. The hermitage is situated in an open field surrounded by woodlands. The area in the immediate vicinity of the hermitage is planted with lawn, trees, shrubs, and flower beds. Access to the hermitage is provided by a private road from Demontreville Trail. The distance between the hermitage and Demontreville Trail is approximately ½ mile. Since we live at the Hermitage, and since our way of life is relatively secluded, we leave the Her- mitage infrequently, and therefore we do not generate a significant amount of traffic. Visitors to our Her- mitage now average 1-2 per day. Additionally, we have regular mail delivery and occasional deliveries by UPS or FedEx. Our new chapel will be open to the public during the day and may generate an increased number of visitors. Because of the remoteness of our property and the fact that we do not advertise, we do not anticipate an increase of visitors beyond an average of 10-15 per day. We do not operate any pro- grams for the public, although we may have a special celebration a few times per year to which guests are invited. We do not anticipate any adverse effects upon the natural areas of our property during or after the construction of the chapel. 2d, ii. We currently have seven members in our community, and we may eventually grow to a maximum of twelve members. We have two part-time employees who help to maintain our grounds and buildings. The Hermitage opens to the public at 7:30 AM and closes at 4:30 PM. We have a gate which prevents access to the hermitage after-hours. Our community building provides living and work spaces for the members of the community, includ- ing a kitchen, dining room, laundry, shower room, library, infirmary, and mechanical room. To the west of the community building and attached to it lies the cloister. This consists of a quadrangle surrounded by covered walkways which allow passage from one building to another under a roof. The open interior of the cloister is landscaped with flowerbeds and a pool. Off the north and south sides of the cloister are found the bedrooms of the members of the community. The new chapel will be situated just west of the cloister. The chapel will be used for liturgical services and for personal prayer. It has a planned seating capacity of 42 guests, in addition to the members of our community (12 maximum). 2e, i. Since the parcel of land upon which the chapel will be built is very large and since the chapel will be lo- cated in the middle of the parcel, we do not foresee that the chapel will cause any inconvenience or dis- turbance to the neighborhood or to the City. Our community greatly values silence as an appropriate at- mosphere for prayer and personal reflection. None of the activities carried on in the new chapel will cre- ate noise. The chapel will be built of durable and noble materials which will enhance the beauty of the neighborhood. The safety of our grounds and buildings is important to us. No toxins or harmful waste products are produced as a result of activities at our monastery, and we are committed to recycling and energy conservation. 2e, ii. Our parcel of land has always been and continues to be zoned as Public Facility. No change in land use is envisioned in our plans. Since our parcel of land is heavily wooded and borders Lake Demontreville on its west side, we in no way interfere with the development plans of the City of Lake Elmo. The comprehen- sive plan is for public/park. The rural character of the area will not be changed by the addition of the new chapel building. 5 2e, iii. Our property is bordered on the south and east by low density private housing, on the north by the Jesuit Retreat House, and on the west by Lake Demontreville. Woodland separates our buildings from the sin- gle-family neighborhoods which border our property to the east and to the south. Woodlands also separate us from the Jesuit Retreat House. There is no direct view of our buildings from any neighboring property. There is no incompatibility between our hermitage and the existing neighborhood. We have excellent re- lations with our neighbors. Many have told us that they are very grateful to live next to our hermitage both because of the prayerful and religious nature of our life and also because of our extensive wood- lands. The Jesuit Retreat House shares the same prayerful and religious activities as we do. Far from being incompatible, our institutions belong to the same church and share a common way of life. The one priest who is resident at the Jesuit Retreat House opposes our new chapel because of a fear that it will increase traffic on the roadway which passes through Jesuit property to reach our hermitage. We have told him that we will work with him to minimize any disturbance to the retreats which take place from Thursday even- ing through Sunday evening most weeks. Since we do not advertise in any way nor offer programs for the public, we do not anticipate large crowds coming to our hermitage. Visitors will be intermittent and will usually arrive in a single car. By contrast, there may be fifty or more cars which come to and leave from the Jesuit Retreat House at the beginning or end of the weekly retreat. Trucks make food deliveries during the week and a laundry truck comes each week to replace sheets and towels. The Retreat House employs far more people than our Hermitage, and this also adds to the traffic in the area. 2e, iv. Our project conforms to Article 7 of the Zoning Code, including general requirements for parking as re- gards dimensions and number of parking spaces. 2e, v. The project is not in a flood plain. The project is in a shoreland district. The project meets the setback and lot area requirements of the ordinance. Demontreville Lake is a recreational development lake. The pro- ject is a permitted use in the shoreland district Ordinance Proposed Setback County Road 50 2750’ Setback Public Street 20 1025’ Setback OHW 200 980’ Setback top of bluff 30 220’ Setback OHW- Septic 75 810’ Maximum impervious cover- age 15% 1.2% 6 2e, vi. The new chapel will be constructed of the same materials as the existing buildings of the hermitage (brick and stone). The monastery of the Carmelite nuns is also a brick structure. The main building complex of the Jesuit Retreat House is a limestone structure. No change in the character of the area will result from the construction of our chapel. The nearest land uses are also religious. 2e, vii. The chapel will be isolated from neighbors and will not create a hazard or nuisance to existing or future neighboring structures. 2e, viii. The project will be served adequately by existing public services and will not create any additional de- mand for public services. The site utilizes an onsite well and onsite septic system. In 1991 officials from the Lake Elmo Fire Department visited our Hermitage to determine whether our site presented any diffi- culties of access for the fire department. Fire Chief Dick Sachs stated in writing that our site did not pose any problems to his department. (See attached letter.) 2e, xi. The project will not create a need for additional public services or facilities. No detriment to the economic welfare of the community will result from the construction of our chapel. 2e, x. The chapel will be used for religious purposes by the residents of the Hermitage. Guests and visitors will have access to the chapel at suitable hours of the day. The chapel has a planned seating of 42 persons, but we do not anticipate having nearly this many people at our services on a daily basis. At the present time, we have no more than 0 to 10 visitors a day. Most days the number is 0 to 2. The new chapel will not pro- duce noise, smoke, fumes, glare, or odors, and the increase of traffic on account of the chapel will be min- imal. 2e, xi. The site is accessed via a collector street (Demontreville Trail) and a private drive. The additional traffic generated by the chapel is estimated to be 8 average daily trips on most days of the year and 30 average daily trips on a few occasions in a calendar year. Most trips will occur during non-peak hours. 7 2e, xii. The new chapel will be built in an open field and will result in very minimal tree removal (8-10 ever- greens which we ourselves had planted). No wetlands will be impacted. The chapel will be located 980’ feet from Lake Demontreville. The final phase of our monastery building program will consist of a build- ing for visitors and guests as well as some rooms for community workshops and library. Landscaping Plan Because the area around the chapel will be further developed with a guest building, workshops and a small library, we do not plan extensive landscaping around the chapel. Lawn grasses, some foundations shrubs, and a few flower beds will be planted and mulched with wood chips. Mr. Ken Roberts thought that, under these circumstances, it would not be necessary to submit a separate landscaping plan. 1 | P a g e 5/8/19 Carmelite Monastery 8249 Demontreville Trail N Lake Elmo MN 55042 SSTS Design Summary Report On April 19th, 2019, a site evaluation was conducted at 8249 Demontreville Trail N, MN 55082 in Washington County. The PID number is 09.029.21.12.0002 Scope of Report The purpose of the design report is to create a plan for a new sub-surface treatment system to treat wastewater from the new chapel to be built at the address above. This design details the plan for the re quired tanks and soil treatment dispersal areas per Washington County Development Code, Chapter Four Subsurface Sewage Treatment System Regulations, Ordinance 206. The system is designed for an Assembly Hall w/ no kitchen plus two (2) full-time employees which will be at the Chapel during day. The system components will be a Type I designed Mound and a total of three Septic & Pump Tanks (1,000- gal; 1,000-gal & 1,000-gal).See Site Plan. Preliminary & Field Evaluation Work The Washington County Maps GIS data (https://maps.co.washington.mn.us/WCGIS/) was used to determine all property lines, utility Right of Ways, roads and other necessary features required by Ordinance 206, Section 9, Subparts 9.2 thru 9.3 prior to and during site evaluation. See Site Plan for details. The information available at MN Well Index (https://mnwellindex.web.health.state.mn.us/) does not indicate the location of any wells within 100 feet of the proposed area. Section MN Well Index – Research. The Web Soil Survey data (https://websoilsurvey.nrcs.usda.gov/app/WebSoilSurvey.aspx), which is provided by the USDA, was gathered to determine the soil characteristics of the area prior to a field evaluation. See Section Web Soil Survey – Research for more details. The field evaluation included staking a 50’ x 26’ soil absorption area, measurements from all setbacks and property line, elevations for absorption area, tanks and soil observations and a minimum of four (4) soil observations within or on the edge of the proposed absorption area for the Soil Treatment Area (STA) and an additional four (4) soil observations were conducted in second Soil Treatment Area identified for future use located to the South of the new Mound. Soil Observations The soil borings and pits were conducted, classified and recorded to meet the Washington County Ordinance 206, Section 9, 9.5 thru 9.7. Redox was observed in all Borings & Soil Pits. The limiting layer was observed at 14” at SB1. See attached Soil Observation Logs. teinbrecher S ROLL-OFFS SEPTIC SYSTEMS EXCAVATING LANDSCAPING DEMOLITION Companies, Inc. 13792 247th Avenue – Zimmerman, MN 55398 Phone (763) 274-0925 Fax (763) 274-0928 2 | P a g e Wastewater Sources & Flows The new Chapel is expected to have a seat capacity for 80 guests with 2 employees on staff full-time. The estimated Peak Flow rate is 350 gallons per day (gpd) was calculated using values provided by Chapter 7081.0130, Table I: Estimate design sewage flow from other establishments. A safety factor of 20% was applied to calculate the final Design Peak Flow of 400 gpd. The Organic Load was calculated using the Estimate of Waste Strengths from Other Establishments chart provided with the University of Minnesota – SSTS Design Forms Worksheet (see U of MN Design Forms).The total Organic Loading Rate for 400 gpd for 80 guests (.01 #s / seat) & 2 full-time employees (.05 #s /employee) is .90 pounds of BOD per day which will need to be treated each day. This equals 269 mg/L of BOD per day. If the system was used to max capacity each day, this level of effluent would be considered At-Risk Effluent and might need to be sampled regularly to ensure treatment level C prior to dispersal to the Mound. However, the Septic Tanks, the Dose Tank & Soil Treatment Area have been designed to handle the worst-case scenario flow-rate & waste-strength from this building The septic tanks & dose tank are sized to provide a retention time of 5 days (typical is 3-days retention) & a storage capacity of 2 x Peak Flow in the event of unexpected pump failure. The total size of the Soil Absorption Area was increased 25% to account for a potential of At-Risk Organic Loading rates of BOD & TSS. The Peak Design Flow rate of 400 gpd for a typical Type I system receiving Residential Strength Waste (170 mg/L BOD) would require 1,040 sqft of absorption in Silt Loam soil. The increased size was calculated using the University of Minnesota Chart (Table 5.1; Manual for Septic System Professionals in Minnesota) for determining Organic Loading Rate. The equivalent loading rate for Silt Loam is 0.0007 #/sqft. The required absorption for .90 #s/day BOD @ 400 gpd with an Organic Loading rate of .0007 #/sqft is 1,280 sqft. Type I Mound The total area for the STA will impact 3,837 sqft (45.3’ x 84.7’) located to the South of the new Chapel. The newly constructed mound will have an Absorption Area of 1,300 sqft (26’ x 50’). The observations found redoximorphic soil conditions at 14 inches from the surface and will require 22” of washed- mound sand to achieve the necessary vertical separation from the most limiting layer. The required materials for the sewer line, distribution network, pumps, piping, sand, rock, fill and cover are detailed in the design worksheets included with this design. Please note, all calculations for materials and pumps are estimates. Actual values may change slightly and will need to field verified for correctness. See U of MN Worksheets for more details. The pump used for dosing the pressure bed must deliver a minimum of 22 gallons per minute and overcome a total dynamic head pressure of 16 feet. All supply pipes and laterals shall be built to specifications and drain-out completely after each dose to prevent freezing. A second 1,300 sqft area was identified and staked-off for future use. No structures or vehicle traffic can occur over this area. Precautions should be taken in the years to come to avoid damaging, compacting or disturbing this area. Special Conditions 1. Due to the large flat area, drainage should be maintained throughout the area to avoid ponding around the tanks or at the edges of the Mound. 2. No final sewer elevation was provided by the builder. Elevation and locations are subject to change. No tank can be buried deeper than 4’ below grade. 3 | P a g e 3. Drainback for Supply Line & Freezing - The slope from the Pressure Bed Supply Line must drain back to the dose tank. Additional depth or insulation may be necessary to keep line from freezing if the supply line is buried too shallow. 4. Setbacks to Easements & Property Lines –There was no survey performed prior to site evaluation, so all measures are estimates. The owner and Installer will need to make sure all construction is within required setbacks. Other Considerations 6.1 Building Permit requirements. No construction shall be allowed by any local unit of government until the permit required for the subsurface sewage treatment system has been issued.9.11 Site Protection 9.11 Site Protection Prior to and during construction or lot improvements, the proposed initial and replacement soil treatment and dispersal areas shall be protected from disturbance, compaction, or other damage by use of stakes and silt fence or snow fence. As-Built Drawing The Licensed Installer must provide an As-built of the final location of all components.

Your septic system is designed to kill harmful organisms and remove pollutants before the water is recycled back into our lakes, streams and groundwater. This management plan will identify the operation and maintenance activities necessary to ensure long- term performance of your septic system. Some of these activities must be performed by you, the homeowner. Other tasks must be performed by a licensed septic maintainer or service provider. However, it is YOUR responsibility to make sure all tasks get accomplished in a timely manner. The University of Minnesota’s Septic System Owner’s Guide contains additional tips and recommendations designed to extend the effective life of your system and save you money over time. Proper septic system design, installation, operation and maintenance means safe and clean water! Property Owner Email Property Address Property ID System Designer Contact Info System Installer Contact Info Service Provider/Maintainer Contact Info Permitting Authority Contact Info Permit # Date Inspected Keep this Management Plan with your Septic System Owner’s Guide.

Your toilet is not a garbage can. Do not flush anything besides human waste and toilet paper. No wet wipes, cigarette butts, disposal diapers, used medicine, feminine products or other trash! The system and septic tanks needs to be checked every _____ months Your service provider or pumper/maintainer should evaluate if your tank needs to be pumped more or less often. Seasonally or several times per year Leaks. Check (listen, look) for leaks in toilets and dripping faucets. Repair leaks promptly. Soil treatment area.Regularly check for wet or spongy soil around your soil treatment area. If surfaced sewage or strong odors are not corrected by pumping the tank or fixing broken caps and leaks, call your service professional. Untreated sewage may make humans and animals sick. Keep bikes, snowmobiles and other traffic off and control borrowing animals. Alarms. Alarms signal when there is a problem; contact your service professional any time the alarm signals. Lint filter. If you have a lint filter, check for lint buildup and clean when necessary. If you do not have one, consider adding one after washing machine. Effluent screen.If you do not have one, consider having one installed the next time the tank is cleaned along with an alarm. Annually Water usage rate. A water meter or another device can be used to monitor your average daily water use. Compare your water usage rate to the design flow of your system (listed on the next page). Contact your septic professional if your average daily flow over the course ofa month exceeds 70% of the design flow for your system. Caps.Make sure that all caps and lids are intact and in place. Inspect for damaged caps at least every fall. Fix or replace damaged caps before winter to help prevent freezing issues. Water conditioning devices.See Page 5 for a list of devices. When possible, program the recharge frequency based on water demand (gallons)rather than time (days). Recharging too frequently may negatively impact your septic system. Consider updating to demand operation if your system currently uses time, Review your water usage rate.Review the Water Use Appliance chart on Page 5. Discuss any major changes with your service provider or pumper/maintainer. During each visit by a service provider or pumper/maintainer Make sure that your service professional services the tank through the manhole. (NOT though a 4” or 6” diameter inspection port.) Ask how full your tank was with sludge and scum to determine if your service interval is appropriate. Ask your pumper/maintainer to accomplish the tasks listed on the Professional Tasks on Page 4. 36 Septic System Management Plan for Above Grade Systems - 4 - Professional Management Tasks These are the operation and maintenance activities that a pumper/maintainer performs to help ensure long- term performance of your system. At each visit a written report/record must be provided to homeowner. Plumbing/Source of Wastewater Review the Water Use Appliance Chart on Page 5 with homeowner. Discuss any changes in water use and the impact those changes may have on the septic system. Review water usage rates (if available) with homeowner. Septic Tank/Pump Tanks Manhole lid. A riser is recommended if the lid is not accessible from the ground surface. Insulate the riser cover for frost protection. Liquid level. Check to make sure the tank is not leaking. The liquid level should be level with the bottom of the outlet pipe. (If the water level is below the bottom of the outlet pipe, the tank may not be watertight. If the water level is higher than the bottom of the outlet pipe of the tank, the effluent screen may need cleaning, or there may be ponding in the soil treatment area.) Inspection pipes. Replace damaged or missing pipes and caps. Baffles. Check to make sure they are in place and attached, and that inlet/outlet baffles are clear of buildup or obstructions. Effluent screen. Check to make sure it is in place; clean per manufacturer recommendation. Recommend retrofitted installation if one is not present. Alarm. Verify that the alarm works. Scum and sludge. Measure scum and sludge in each compartment of each septic and pump tank, pump if needed. Pump Pump and controls. Check to make sure the pump and controls are operating correctly. Pump vault. Check to make sure it is in place; clean per manufacturer recommendations. Alarm. Verify that the alarm works. Drainback. Check to make sure it is draining properly. Event counter or elapsed time meter.Check to see if there is an event counter or elapsed time meter for the pump. If there is one or both, calculate the water usage rate and compare to the anticipated use listed on Design and Page 2. Dose Volume: __________ gallons: Pump run time: _________ Minutes Soil Treatment Area Inspection pipes. Check to make sure they are properly capped. Replace caps and pipes that are damaged. Surfacing of effluent. Check for surfacing effluent or other signs of problems. Lateral flushing.Check lateral distribution; if cleanouts exist, flush and clean at recommended frequency. Vegetation -Check to see that a good growth of vegetation is covering the system. All other components – evaluate as listed here: 80 On Demand Septic System Management Plan for Above Grade Systems - 5 - Water-Use Appliances and Equipment in the Home Appliance Impacts on System Management Tips Garbage disposal Uses additional water. Adds solids to the tank. Finely-ground solids may not settle. Unsettled solids can exit the tank and enter the soil treatment area. Use of a garbage disposal is not recommended. Minimize garbage disposal use. Compost instead. To prevent solids from exiting the tank, have your tank pumped more frequently. Add an effluent screen to your tank. Washing machine Washing several loads on one day uses a lot of water and may overload your system. Overloading your system may prevent solids from settling out in the tank. Unsettled solids can exit the tank and enter the soil treatment area. Choose a front-loader or water-saving top-loader, these units use less water than older models. Limit the addition of extra solids to your tank by using liquid or easily biodegradable detergents. Limit use of bleach-based detergents and fabric softeners. Install a lint filter after the washer and an effluent screen to your tank Wash only full loads and think even – spread your laundry loads throughout the week. Dishwasher Powdered and/or high-phosphorus detergents can negatively impact the performance of your tank and soil treatment area. New models promote “no scraping”. They have a garbage disposal inside. Use gel detergents. Powdered detergents may add solids to the tank. Use detergents that are low or no-phosphorus. Wash only full loads. Scrape your dishes anyways to keep undigested solids out of your septic system. Grinder pump (in home) Finely-ground solids may not settle. Unsettled solids can exit the tank and enter the soil treatment area. Expand septic tank capacity by a factor of 1.5. Include pump monitoring in your maintenance schedule to ensure that it is working properly. Add an effluent screen. Large bathtub (whirlpool) Large volume of water may overload your system. Heavy use of bath oils and soaps can impact biological activity in your tank and soil treatment area. Avoid using other water-use appliances at the same time. For example, don’t wash clothes and take a bath at the same time. Use oils, soaps, and cleaners in the bath or shower sparingly. Clean Water Uses Impacts on System Management Tips High-efficiency furnace Drip may result in frozen pipes during cold weather. Re-route water directly out of the house. Do not route furnace discharge to your septic system. Water softener Iron filter Reverse osmosis Salt in recharge water may affect system performance. Recharge water may hydraulically overload the system. These sources produce water that is not sewage and should not go into your septic system. Reroute water from these sources to another outlet, such as a dry well, draintile or old drainfield. When replacing, consider using a demand-based recharge vs. a time-based recharge. Check valves to ensure proper operation; have unit serviced per manufacturer directions Surface drainage Footing drains Water from these sources will overload the system and is prohibited from entering septic system.

There was an initial review done in February of 2019, by our then Building Official Mike Bent with regard to the requirement of sprinklers. It was determined that none were required. If the building as presented then is consistent with the current proposal, that determination still stands. The following items need to be addressed: • Must meet all applicable codes in the 2015 MN State Fire Code. These requirements also include Appendix D, FIRE APPARATUS ACCESS ROADS. • With this building not requiring sprinklers, special attention to the following: o 503.1.1 “……shall extend to within 150 feet of all portions of the facility…” o Appendix D, Section D105 must be addressed regarding the height of the building (couldn’t determine on my plans) and if this section is applicable. • Will there be any fire hydrants brought into the site? • Location of Lockbox approved by Fire Chief • Location of alarm annunciator panel approved by Fire Chief. • Provide basic overhead view foot print plan of the building, non-architectural, showing rooms, access, utility locations, etc. Greg Malmquist, Fire Chief LAKE ELMO FIRE DEPARTMENT Station #1 3510 Laverne Ave. No. Lake Elmo, MN 55042 651-770-5006 ________________________ Station #2 4259 Jamaca Ave. No. Lake Elmo, MN. 55042 651-779-8882 ________________________ 1 Tanya Nuss From:falzonezone <falzonezone@gmail.com> Sent:Sunday, June 16, 2019 9:11 PM To:Ken Roberts Subject:Lake Elmo Planning Commission Caution: This email originated outside our organization; please use caution. To the Planning Commission of the City of Lake Elmo: Regarding the proposed “Chapel” at the Carmelite Hermitage of the Blessed Virgin Mary, I speak on behalf of my family at 5124 Isle Avenue North, Lake Elmo, to say that we absolutely support the construction of a new chapel. However, a few years ago, it was mentioned that this new building would require adding a roadway through our street for new access to the Chapel. I am writing to share that we vehemently oppose the construction of a roadway through Isle Avenue. We have shared a property line with the Carmelites for just over 20 years, and they have been phenomenal neighbors. My family supports their devoted and faith-filled lifestyle, so we are completely in favor of building the Chapel. We want them to do that! However, we feel they should maintain access where it has always been – along DeMontreville Trail. Adding a roadway through Isle Avenue would disrupt the quiet, residential neighborhood that drew us here originally. When adding a roadway through Isle Avenue was discussed a few years ago, I was inf ormed by sources affiliated with the city that Isle Avenue was not constructed to withstand consistent vehicular traffic – its weight capacity simply is not enough. Even though the Chapel will not draw many visitors, its weight rating would still need to be adequate, and our street just was not built that way. We love the city of Lake Elmo. It is where our kids grew up, it’s where most of our family lives, and it’s where we are blessed to call home. Our street has been the place where all of the neighborhood kids grew up playing with each other, where we have gone for countless family bike rides and walks, and where we can take a deep breath from the fast- paced reality of our professional lives. Isle Avenue is a sanctuary for many of us – not just for my family. It is a safe place. It is a quiet place. It is a lightly- traveled dead end. Because of what this neighborhood means to us, we sincerely ask that you consider maintaining the existing access for the new Chapel. That said, we wish the Carmelites all the best in the construction of their Chapel. It will be a great addition for their lives, and we are excited for them! Thank you for considering! Craig Falzone and family 5124 Isle Avenue North Lake Elmo, MN 55042 Sent from my T-Mobile 4G LTE Device STAFF REPORT DATE: 8/12/2019 REGULAR ITEM#: 4A – PUBLIC HEARING MOTION TO: Planning Commission FROM: Ken Roberts, Planning Director AGENDA ITEM: Variance – Direct Access for a Place of Worship REVIEWED BY: Ben Prchal, City Planner BACKGROUND: The City has received a request from Rev. John Burns of the Carmelite Hermitage for a variance from the City Code requirement about direct access for a place of worship. He is making this request in order to add a chapel to the Carmelite’s site located at 8249 Demontreville Trail. On December 3, 1991, the City Council approved a variance from the section of the City Code about having frontage a public road for the Carmelite Monastery. The Carmelites made this request so they could construct a building on their parcel (which does not have frontage on a public road). (See attached City Council Resolution 91-40). ISSUE BEFORE COMMISSION: The Commission is being asked to hold a public hearing, review and make recommendation on the above mentioned variance request. VARIANCE REQUEST DETAILS/ANALYSIS: Deadline for Action: Application Complete – 7/12/2019 60 Day Deadline – 9/11/2019 Extension Letter Mailed – N/A 120 Day Deadline – N/A Applicable Regulations: Article V - Zoning Administration and Enforcement Article XIV – Public and Semi-Public Districts Variance Request: The Carmelite Hermitage of the Blessed Virgin Mary requests a variance from the direct access requirement for places of worship as outlined in Section 154.600(B)(2) of the City Code. 2 Reason for Request. The reason for the variance request is to facilitate the construction of a chapel on their site. The City Code requires places of worship (such as chapels and churches) to have “direct access” to a public street classified by the Comprehensive Plan as a major collector or arterial. The Carmelites property does not have frontage on Demontreville Trail but there is an existing easement across the neighboring property to the north that provides their property with access to Demontreville Trail. The Comprehensive Plan classifies Demontreville Trail as a major collector street. The applicant believes their existing access to Demontreville Trail (with the easement) meets the direct access requirement of the City Code. If the City Code said that places of worship are required to have access to a major collector or arterial street, then the Carmelites site would meet that access requirement. REVIEW AND ANALYSIS/DRAFT FINDINGS An applicant must establish and demonstrate compliance with the variance criteria set forth in Lake Elmo City Code Section 154.109 before the City may grant an exception or modification to city code requirements. These criteria are listed below, along with comments from Staff about the applicability of these criteria to the applicant’s request. 1) Practical Difficulties. A variance to the provision of this chapter may be granted by the Board of Adjustment upon the application by the owner of the affected property where the strict enforcement of this chapter would cause practical difficulties because of circumstances unique to the individual property under consideration and then only when it is demonstrated that such actions will be in keeping with the spirit and intent of this chapter. Definition of practical difficulties - “Practical difficulties” as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by an official control. FINDINGS: The addition of a chapel to Carmelites site has been planned since at least 1991 when the City first approved a Master Plan for their site. The Carmelites have been using the easement to Demontreville Trail for access to the site since that time. Adding another driveway or access to the Carmelites property would be a practical difficulty as the only public street their property has frontage on is Hidden Bay Trail to south. A new driveway would be about 1,500 feet in length, would require extensive tree removal and grading and would be an access onto a local street – not a collector or arterial street as the City Code requires for places of worship. The use of the existing driveway for access to Demontreville Trail for the addition of a chapel to site is a reasonable use of the property and the existing access. 2) Unique Circumstances. The plight of the landowner is due to circumstances unique to the property not created by the landowner. FINDINGS: According to the applicant, the existing lot layout with the access easement to Demontreville Trail has been in place since 1904. This is a unique situation with circumstances not created by the landowner or the current land users – the Carmelite Monks. 3) Character of Locality. The proposed variance will not alter the essential character of the locality in which the property in question is located. FINDINGS: The proposed variance will allow the Carmelites to use the existing driveway (that currently provides access to their site) for access for the proposed chapel. By using the existing 3 driveway that has been in place for many years, the Carmelites will not be altering the essential character of the locality (or area) in which their property is located. Conversely, adding another driveway to their site that would have access onto a local, neighborhood street would change the character of that locality and area of the City. 4) Adjacent Properties and Traffic. The proposed variance will not impair an adequate supply of light and air to properties adjacent to the property in question or substantially increase the congestion of the public streets or substantially diminish or impair property values within the neighborhood. FINDINGS. The proposed variance to allow the use of the existing driveway and easement for access for the proposed chapel will not impair an adequate supply of light and air to properties adjacent to the subject property, increase congestion of public streets or substantially diminish or impair property values within the neighborhood. Conversely, as I noted above, if the applicant added another driveway to access the streets to the south of their site that would increase the congestion on the local public streets near their property. FISCAL IMPACT: Staff has not found that the proposed variance will have any impact to the City. OPTIONS: The Planning Commission may: • Recommend approval of the proposed variance. • Recommend approval of the proposed variance with recommended conditions. • Recommend denial of the variance, citing recommended findings of fact for denial. RECOMMENDATION: Staff recommends that the Planning Commission recommend approval of the request from Rev. John Burns of the Carmelite Hermitage for a variance from the City’s requirement for direct access to a major collector or arterial street for a place of worship for the property located at 8249 Demontreville Trail. “Move to recommend approval of the request from Rev. John Burns of the Carmelite Hermitage for a variance from the City’s requirement for direct access to a major collector or arterial street for a place of worship for the property located at 8249 Demontreville Trail.” ATTACHMENTS: 1) Variance request narrative dated July 12, 2019 (4 pages) 2) Proposed Site Plan 3) Resolution 91-40 - Variance resolution 1 of 4 Land Use Application – Variance 12 July 2019 Property Location All of Government Lot 4 in Section 9, Township 29 north, Range 21 west, City of Lake Elmo, Washington County, Minnesota, according to government survey containing 59.4 acres of land. Also the south 30.6 acres of Government Lot 4 in Section 4, and of the southwest quarter of the southeast quarter of said Section 4, all in Township 29 north, Range 21 west, according to government survey, being the south 688 feet thereof. Detailed Reason for the Request In 1954, the Discalced Carmelite Nuns of Saint Paul, a non-profit corporation under the laws of the State of Minnesota, were looking for property upon which to build a permanent monastery. They were advised of the property which they now own and entered into negotiations with the owners of the property. On 2 February 1954, Phillip C. Mackey and his wife Bernadine R. Mackey conveyed their property, along with its easement, to the Discalced Carmelite Nuns of Saint Paul by warranty deed, dated that day, and filed for record in Washington County, Minnesota, on 4 February 1954. As part of their deed of purchase, they obtained a right of way across the neighboring property to the north (owned by the Jesuit Retreat House) which gave them access to Demontreville Trail. This right of way has existed since 1904. At the time that the Carmelite Nuns purchased their property, the right of way across the Jesuit property was the only access from a public road to the Carmelite property, and it remains the only access today. The Carmelite Nuns have used this right of way continuously for 64 years. In 1987 Carmel of the Blessed Virgin Mary (aka Carmelite Hermitage, Carmelite Hermitage of the Blessed Virgin Mary) was incorporated in the State of Minnesota as a community of Carmelite Priests and Brothers. In December of 1991, the City of Lake Elmo approved a master plan for the Carmelite Hermitage consisting of four phases: Phase 1, consisting of a community building and garage was constructed in 1991/92. Phase 2, consisting of a central courtyard with covered walkways (cloister) was constructed in 2001/2002. Phase 3 consists of a chapel and is the building we would now like to construct. Phase 4 will consist of a guest building and library. We hope to commence Phase 4 around 2022. Additionally, in 1991 the City of Lake Elmo granted a variance to the Carmelite Hermitage because the Hermitage also uses the easement over Jesuit land to access Demontreville Trail. The Jesuit Retreat House made no objection to the variance. The Carmelite Fathers and Brothers have used the easement continuously for 32 years. In the intervening years, the Carmelite Hermitage has built four new buildings. In 2007, it requested and received an amendment to its master plan to add an additional building. This building was built in 2008. In none of the four construction projects did the City of Lake Elmo require the Carmelite Hermitage to obtain an additional variance. We maintain that our variance is valid for all buildings shown on the master plan which was approved by the City Council in 1991. City practice towards our Hermitage is evidence of our interpretation. 2 of 4 The Carmelite Hermitage wishes to construct its chapel, shown as phase three on its master plan. An objection has been raised by the Jesuit Retreat House that the Carmelite Hermitage needs a new variance to proceed with its chapel project because it does not meet the CUP requirements established by the City in 2000 and amended in 2006. Since there is doubt about the scope and language of the original variance as well as doubt about the meaning of the word direct in the City’s CUP requirements, City staff have suggested that we apply for a new variance that will clarify all issues related to access to our property. In a spirit of cooperation, we have agreed to apply for a new variance. Variance Request, Practical Difficulties: The Carmelite Hermitage of the Blessed Virgin Mary requests a variance from the direct access requirement of Section 154.600(B)(2) of the City Code. It further requests that the variance apply to all 90 acres of the property owned by the Discalced Carmelite Nuns of St. Paul and that the variance apply to all buildings currently existing on the property as well as all buildings shown on its approved master plan which remain to be built. Strict enforcement of the City Code requiring direct access creates not only a practical difficulty but a serious hardship in that we would be unable to complete our monastery as planned and approved in 1991 by the City of Lake Elmo. In 1991, The City Council recognized the hardship that existed with regard to access to our property, and the Council granted us a variance at that time. 2. a.

The Carmelite Hermitage of the Blessed Virgin Mary requests a variance from the direct access requirement of Section 154.600(B)(2) of the City Code. It further requests that the variance apply to all 90 acres of the property owned by the Discalced Carmelite Nuns of St. Paul and that the variance apply to all buildings currently existing on the property as well as all buildings shown on its master plan which remain to be built. 2.e. In December of 1991, the City of Lake Elmo approved the master plan of the Carmelite Hermitage consisting of four phases: Phase 1, consisting of a community building and garage was constructed in 1991/92. Phase 2, consisting of a central court yard with covered walkways (cloister) was constructed in 2001/2002. Phase 3 consists of a chapel and is the building we would now like to construct. Phase 4 will consist of a guest building and library. Additionally, the City of Lake Elmo granted a variance to the Carmelite Hermitage in 1991 since the Hermitage also used the easement over Jesuit land to access Demontreville Trail. The Jesuit Retreat House made no objection to the variance. An attorney for the Jesuit Retreat House sent a letter to the City Attorney contending that the variance of 1991 is not valid for the construction of the chapel because the CUP code enacted by the City in 2000 and amended in 2006 requires direct access to a collector road or major arterials. The City Attorney stated that an argument can be made that we do not have direct access. Furthermore the City Attorney contends that the 1991 variance applied only to the building 4 of 4 which we built in 1991. We dispute this interpretation because it contradicts the practice of the City to date. We have built several buildings since 1991, including one in 2007 which required an amendment to our master plan, and in none of these cases did the City require a new variance. At a meeting with the City Attorney and the Director of Planning held at City offices on 2 July 2019, we stated our point of view. Nevertheless, we agreed to apply for a new variance in order to clarify all issues related to access to our property. 2.f. The circumstances of our property are quite unique in that the property has never bordered a public road since it was divided from the property to the north in 1904. At that time, an unrestricted easement through the northern property was given in order that the southern property could have access to Demontreville Trail. The Discalced Carmelite Nuns received this easement as part of their deed of purchase. In 2011 the Carmelite nuns acquired three small lots that border their property as well as Hidden Bay Trail. The lots are undeveloped and have no driveways into them. Hidden Bay Trail is not a collector road or major arterial street. It is not suitable as an access road to our property. Strict enforcement of the City Code requiring direct access creates not only a practical difficulty but a serious hardship in that we would be unable to complete our monastery as planned and as approved by the City of Lake Elmo in 1991. 2.g. Our plight was in no way created by ourselves; it is rather the result of the division of the property in 1904. Our circumstances were recognized as unique by the City Council in 1991, and for this reason the Council granted us a variance. 2.h. Far from altering the essential character of the neighborhood, granting a variance will maintain the essential character of the neighborhood as it has always been since the Carmelite Nuns purchased the property in 1954. Building a driveway to Hidden Bay Trail would alter the neighborhood and is vehemently opposed by our neighbors on Hidden Bay Trail and Birch Bark Trail.
