Below is the Stormwater Management Memo detailing the drainage design calculations and BMPs included in this project, as well as pertinent attachments. EXECUTIVE SUMMARY The proposed project is located at 4913 Sunnyslope Rd E in Edina, Minnesota (“Site”). The proposed disturbance area for this project is under 1.o acres, therefore the City of Edina (“City”) has only required that this Site follow rate and volume control restrictions and the project should have no net fill. The purpose of this memo is to address these regulations. This project includes demolishing and building a new single-family home, demolishing and relocating the driveway, grading a rain garden in the front yard, burying storage pipes in the rear yard and grading to tie into existing elevations that will disturb less than one acre of total area. The proposed design intends to use a rain garden in the front yard that controls lees than 600 sf of new impervious area and underground storage pipes that collect the roof runoff in the back yard to help control the runoff rate as it leaves the Site towards Sunnyslope Rd E and Minnehaha creek. We analyzed the existing and preliminary proposed Site hydrology using HydroCAD. To estimate existing and proposed runoff rates we performed hydrology modeling for the existing and proposed Site. We divided the Site into drainage boundaries, input land use, soils information, surface storage, and precipitation depths corresponding to the required design storms. This project site contains loamy type soils, which are commonly Type B soils and good for infiltrating storm runoff. A Soils Map showing the entire Site can be found in Attachment C. The proposed stormwater management design will collect the site runoff from the driveway in a rain garden in the NW corner of the property and collect the roof runoff into underground storage pipes in the backyard to slow down the runoff. Comparing this BMP to the existing conditions against the 10-, and 100-yr design storms shows that the proposed design does not increase runoff rates and volumes. PROPOSED CONDITION CALCULATIONS The proposed BMP is a depressed area with an overland EOF in the rear of the property. This BMP will improve the overall runoff rate as well as providing some volume reduction. Since the Soils Map show Type B soils onsite, we assumed an infiltration rate of 0.45 in/hr and set the maximum overflow elevation of the BMP’s to a height of 1.8’ from the bottom of the BMP to ensure that the collected runoff will draw down completely within 48 hours (per general MPCA requirements).

Since the amount of new impervious draining towards the areas of structural drainage issues is less than 600 sf of new impervious, the City’s volume control requirement is not applicable to this project. Therefore, the BMP’s are designed to retain the stormwater long enough to reduce the proposed design’s 10-yr discharge rate and volume below the existing values. Refer to the Construction Plan Set in Attachment A for site coverage and rate control calculations. Existing drainage patterns around the proposed site will be maintained when tying the grades back into the existing ground elevations, see Construction Plan Set in Attachment A. RATE CONTROL To provide enough volume control and peak flow retention for the 10-year event, runoff was directed to the proposed BMP’s mentioned above. By capturing and filtering stormwater runoff from the project Site, the peak discharge rates and 10-yr discharge volumes do not exceed the existing runoff rates & volumes. Table 1 shows the peak comparisons for the total site discharge. Overall, the HydroCAD model showed no increase in runoff rates in the Proposed design. Table 1 Peak Runoff Rates 1 See Attachment B HydroCAD report: Existing. 2 See Attachment B HydroCAD report: Proposed. CONCLUSION The proposed stormwater management plan for the residence at 4913 Sunnyslope Rd E will implement stormwater best management practices that provide enough rate control for the project Site. The proposed stormwater management plan for the Site consists of the following stormwater BMPs: a rain garden in the front yard and underground storage pipes in the back yard. The Site was modeled using HydroCAD for the existing and proposed 10-, and 100-year storm events based on Atlas-14 models to confirm that the project meets the stormwater rate control requirements from the City of Edina despite being below the disturbed area threshold. Our findings indicate the Site will successfully achieve the goals for peak runoff rate and volume rate.

The existing home is a 1 ¾ story home with a tuck under garage built in 1941. The applicant is requesting a 1.16-foot first floor height variance for a tear-down rebuild/new home. The variance request is to allow the first floor of the new home to sit 2.16 feet higher than the existing first floor of the home, 1.16-foot higher than the allowed 1-foot height increase. The FEMA 1%-annual chance flood elevation on the subject property is 888.2’, therefore the lowest floor is required to be no less than 890.2’. The proposed lowest floor elevation is 890.91’. There is also local 1% flood shape located on the subject property. Due to the elevation of the local flood shape, the lowest opening elevation in the front is 894.2’. With exception of the first-floor elevation, the proposed project meets all other zoning requirements.

Yes. Staff believes the variance criteria is met in this instance. Minnesota Statues and Edina Ordinances require that the following conditions must be satisfied affirmatively to grant a variance. The proposed variance will: 1) Relieve practical difficulties that prevent a reasonable use from complying with ordinance requirements. Reasonable use does not mean that the applicant must show the land cannot be put to any reasonable use without the variance. Rather, the applicant must show that there are practical difficulties in complying with the code and that the proposed use is reasonable. The practical difficulty is caused by the floodplain elevation and the basement elevation requirement. The applicant has designed the proposed home where it will comply with the overall height requirement (based on existing grade) with the proposed first floor elevation increase. The increase in first floor elevation will allow for a standard basement ceiling height. 2) There are circumstances that are unique to the property, not common to every similarly zoned property, and that are not self-created? The variance allows the new home basement to be placed out of the flood zone. There is not FEMA flood elevation requirements and local flood shapes on every similarly zoned property. The proposed project provides the elevated basement while still complying with the maximum allowable stucture height as measured from existing grade. 3) Will the variance alter the essential character of the neighborhood? The proposed home design reflects the character of the neighborhood in height, scale, and mass. The maximum height from existing grade will conform even given the increase in 1st floor elevation. The home is appropriate in size and scale for the lot and the surrounding neighborhood. The variance request as proposed raises the subject property’s first floor elevation to be more similar to the two adjacent properties on either side. The properties on either side of the subject property have a first-floor elevation of 904.5. Staff Recommendation Approve a 1.16-first floor elevation variance for a new home at 4913 Sunnyslope Road East. STAFF REPORT Page 4 Approval is subject to the following findings: 1. The proposal meets the variance criteria. The practical difficulty is caused by the floodplain elevation requirements and the elevation of the existing first floor. 2. There is not FEMA flood elevations and local flood shapes on every similarly zoned property. The proposed project provides the elevated basement floor while still complying with the maximum allowable height a measured from existing grade. 3. Granting the variance will not alter the character of the neighborhood. Approval is subject to the following conditions: 1. Plans date stamped July 21, 2021. 2. Comments and conditions listed in the August 2, 2021 Engineering Memo. DATE: 8/2/2021 TO: Cary Teagu e – Plan ning Director FROM: Zuleyka Marquez, PE – Graduate Engineer RE: 4913 Sunnyslope Rd E - Variance Review The Engineering Department has reviewed the subject property for street and u tility concerns, grading, storm water, erosion and sediment control and for general adherence to the relevant ordinance sections. This review was performed at the req uest of the Planning Department; a more detailed review will be performed at the time of building permit application. Plans reviewed included existing and proposed site plans, grading and drainage plan, erosion and sediment control plan, and stormwater management plan stamped July 12, 2021. Summary of Work The applicant proposes to demolish the existing home and proposes a new home. The request is for a variance to the first-floor elevation. Easements A 24 -inch stormwater pipe is located along the southside of the property. A 10’ easement centered on the pipe is requested. The proposed retaining wall on the southside shall be relocated out of the easement area. Grading and Drainage The existing s ite drains to Sunnyslope Rd E and Minnehaha Creek. Drainage paths will be maintained post- construction. Stormwater Mitigation No increase in peak rate to private properties for 10% annual probability event (NOAA Atlas 14, 10 -year). Reduction of volume equal to 1.1 inches times new contributing impervious surfaces required if proposing the addition of over 600 square feet of new impervious surface in areas that drain to structural flooding issues. With less than 600 SF of new impervious directed to the structural flooding issue and no drainage path to private property, the requirements are met. Stormwater was reviewed and is consistent with City of Edina Building Policy SP -003 standards. A final grade as -built survey and inspection will be required to verify compliance with the approved stormwater plan. Floodplain Development The FEMA 1%-annual chance flood elevation is 888.2’ per the FEMA map. Thus, the lowest floor is required to be at no less than 890.2’. The proposed lowest floor elevation is 890.91’. A local 1%-annual chance flood shape is located in the front with an elevation of 892.3’. Thus, the lowest opening elevation in the front is 894.2’. The proposed top of foundation is 900.58’; proposed lowest opening elevation to be indicated on permit plans to confirm compliance. Net fill is not allowed below 892.3’. Sheet C400, Cut & Fill Analysis, indicates a net cut of 8.5 CY. Erosion and Sediment Control An erosion and sediment control plan was reviewed and is consistent with City of Edina Building Policy SP -002. Street and Driveway Entrance The applicant proposes to relocate the existing driveway entrance. A driveway entrance permit will be required . The street was reconstructed in 2005. Refer to standard plate 540 and 543 for patching requirements. Public Utilities Water and sanitary is served from Sunnyslope Rd E. A one-inch water service line from the curb stop to the dwelling is required per the City’s policy SP -024. Miscellaneous A Minnehaha Creek Watershed District permit may be required , applicant will need to verify with the district. Watermain as -built dated 1938 and 1945. Structure built 1941. Minnesota Department of Health (MDH) does not have any well documentation for this site or any other on Sunnyslope Rd E. A well is not likely located onsite. Thus, coordination with MDH will not be required . Tiered retaining walls are proposed . If the combined height or individual walls is/are greater than 4 -feet and the walls are not considered independent (less than 2 times the height of the lower wall in separation), the applicant will be required to s ubmit drawings, cross-section, and calculations prepared and signed by a Minnesota licensed professional engineer.

We appreciated the opportunity to better understand the variance request. The proposed first floor height seemed appropriate and not out of scale compared to neighboring properties. The builder also noted that the house was shifted on the lot to allow more space between the proposed house & neighbor to the north. We would support the variance. It would be great to figure out a good solution to help protect the large tree on the north side of the property. 01.First and Last Name 02.Address 03.Comment Greg Ansems 4907 East Sunnyslope Road, Edina I am against this variance. Having seen the plans for the home, which the builder was more than generous in sharing, it seems like the home is stretching all of the variances in size. It would create a house that is not only bigger on the first floor, but likely dramatically bigger on the second floor and overall on the lot. It wouldn’t fit in the neighborhood. Looking across the creek, they have very strict guidance on what can be done on that side, but it doesn’t seem to apply on this side. I’m not sure why that is. I am against this because it will create a home that is way too big for the lot. Being on the creek, it’s important to have a home that fits within the character of the neighborhood and not overly big. Thank you. -Transcribed by City Staff (voicemail received 8-4-21 at 5:59 PM) Date: August 11, 2021 Agenda Item #: VI I.A.

The Planning Commission is asked to consider a variance request for a 1.3%, or a 210 square foot increase beyond the allowable 25% building coverage limit for property located at 6601 Biscayne Blvd. The original request was heard by the Planning Commission on July 14, 2021, for a 9 - foot rear yard setback variance and a 1.5%, or a 229 square foot increase beyond the allowable 25% building coverage limit. The applicant was directed by the Commission to consider a redesign of the project to reduce or eliminate the rear yard setback request. The redesign has eliminated the rear setback request and reduced the coverage request from 1.5%, (229 sq ft) to 1.3%, (210 sq ft). This project involves removing an existing deck and patio and replacing them with a screened porch and smaller deck. The variance application is for an increase of 1.3% over the allowed 25% lot coverage. Current lot coverage is 29.2% so this project would be a net reduction to 26.3%. The applicant has stated the purpose is to allow enjoyment of their back yard from the upper, (main), level without relying on stairs, as the owners intend to age-in-place. The following page provides a compliance table that demonstrates how the proposal would comply with Standards on the lot. City of Edina • 4801 W. 50th St. • Edina, MN 55424 Compliance Table Principal Structure (House) City Standard Proposed West Side – East Side - South– (previous plan) North Side – 10 feet 15 feet 25 feet 31.4 feet 22 feet 28.4 feet (16 feet*) / 25 feet 34.5 feet Building Coverage- (previous plan) 25% (26.5%*)/ 26.3%* *Requires a variance Highlights/Revised plan: Revised plan conforms to all setbacks including the minimum 25 foot rear yard setback. The previous plans had the addition 16 feet from the rear lot line, requiring a 9 foot setback variance. Original plan had proposed coverage at 26.5%, or 1.5% over the maximum allowable 25%. The new plan reduces the coverage to 26.3%, or a .2%, (19 sq ft), reduction from the original request. The existing property is over on lot coverage at 29.2% coverage. The proposal will bring down the existing nonconforming coverage to 26.3% or 210 sq ft over the 25% maximum. The purpose of the request is to allow the owner’s intent to age-in-place and keep the additions on one accessible level.

I have live there for about 20 years. The Rubin's were living in their house when we moved in. At the fence line between our two properties the Rubin's have a tall evergreen trees that offer a lot of privacy between the two properties. I have looked at their proposal to add a porch off the main level and a ground level deck. I think that these additions to their house would be great for the Rubin's without affecting my property in any way. When we moved in we added a four season porch and deck off of our main level which has added a lot of enjoyment to my family over the years. I support their proposal for a variance. They are reducing the building coverage ratio and the 9 ft variance for the rear yard set back will not change anything for the Joneses. The way it looks is that the porch is encroaching the rear set back, not the open decks so noise would not be any more of an issue. I look forward to see the addition built for the Rubin's. I'm sure their family will enjoy the new space just like Nancy and I have enjoyed our porch and deck. Nancy and Les Jones 16'-0"9'-0"PROPOSED SETBACK July 14, 2021 PLANNING COMMISSION Kris Aaker, Assistant City Planner B-21-20, A variance request for rear yard setback and to exceed the 25% building coverage requirement for a porch addition at 6601 Biscayne Blvd. Information / Background: Property owners, Russel and Karen Rubin, have submitted a variance request for rear yard setback from the 25-foot requirement and to exceed the 25% building coverage requirement for residential lots over 9,000 square feet. The variances requested are for a 9 - foot rear yard setback variance and a 1.5%, or a 229 square foot increase beyond the allowable 25% building coverage limit. The applicant is requesting to add a 382 sq ft porch addition and 150 sq ft deck to the back of the home into the rear yard while removing a deck and reducing the size of their existing 606 sq ft patio. The property is currently at 29.2% coverage, by 4.2% or 641 sq ft over the maximum allowable building coverage of 25%. The proposed project will reduce coverage by 2.7% or 412 sq ft, however, will continue to be over the coverage limit by 1.5% or 229 sq ft. even with the reduction of the patio, is still over the maximum building coverage allowed by code. The proposed building coverage is 26.5% of the lot area. The building coverage calculations include the house, patio (after the first 150 square feet), and attached shed. It does not include the driveway or sidewalk. The proposal will reduce existing coverage and move the property closer to compliance. The back wall of the home is at 45.5 feet to the rear lot line; in compliance with the minimum 25-foot rear yard setback requirement. The proposal is to reduce the required setback to be 16 ft from the rear lot line or a 35% reduction in setback. Decks and patios can be a minimum of 5 feet to the side or rear lot line, however, all portions of the principle structure must be no closer than 25 feet. Surrounding Land Uses Northerly: Single Unit residential homes; zoned and guided low-density residential. Easterly: Single Unit residential homes; zoned and guided low-density residential. Southerly: Single Unit residential homes; zoned and guided low-density residential. Westerly: Single Unit residential homes; zoned and guided low-density residential. STAFF REPORT Page 2 Existing Site Features The existing 15,251.3 square foot corner lot is located in the southwest quadrant of Biscayne Blvd and Londonderry Road. The lot today is at 29.2% building coverage. The existing house accounts for 24% of the lot coverage with the existing 606 sq ft patio and 338 sq ft deck the remainder of coverage. The requested proposal increases the house to account for 26.5% building coverage or a 2.5% increase in principle building area. The existing home complies with coverage limits allowing for an addition of 154 sq ft of building or 236 sq ft if the attached shed is removed, (82.5 sq ft). Although the lot coverage percentage will be reduced, the principle building area of the lot is increasing with the proposal, while it is currently under the maximum. The existing home is conforming at 45.5 feet from the rear lot line allowing for a 20.5-foot extension into the rear yard. There is ample opportunity to maintain the rear yard setback. Planning Guide Plan designation: Low-Density Residential Zoning: R-1, Single-Dwelling District Grading & Drainage The Engineering Department has reviewed the subject property for street and utility concerns, grading, storm water, erosion and sediment control. An Engineering memo is attached. Compliance Table Principal Structure (House) City Standard Proposed West Side – East Side - South– North Side – 10 feet 15 feet 25 feet 31.4 feet 22 feet 28.4 feet 16 feet* 34.5 feet Building Coverage 25% 26.5%* *Requires a variance PRIMARY ISSUES & STAFF RECOMENDATION Primary Issues Is the proposed variance justified? STAFF REPORT Page 3 Minnesota Statues and Section 36-98 of the Edina Zoning Ordinance require that the following conditions must be satisfied affirmatively. The proposed variance will: 1) Relieve practical difficulties that prevent a reasonable use from complying with ordinance requirements. Reasonable use does not mean that the applicant must show the land cannot be put to any reasonable use without the variance. Rather, the applicant must show that there are practical difficulties in complying with the code and that the proposed use is reasonable. Staff questions if the proposal is reasonable. The existing home is well within the rear yard setback requirement of 25 ft allowing for a 20.5 ft extension into the back yard before required setback. Although the existing coverage conditions are greater than what the applicant is asking for, the requirement is the same percentage for all residential lots over 9,000 square feet in Edina. Building permits are not required for patios, and therefore situations where the building coverage is over 25% may occur without staff knowing, creating “existing conditions.” The property would be allowed an addition of 236 sq ft, (with shed removal), 25 feet from the back-lot line and have a deck or patio up to 150 square feet without a variance. 2) There are circumstances that are unique to the property, not common to every similarly zoned property, and that are not self-created? The percentage of building coverage is calculated the same for each lot over 9,000 square feet. The requirement is consistent throughout all residential properties over 9,000 square feet zoned R-1. The back wall of the home is 45.5 feet from the rear lot line allowing for a 20.5-foot addition into the rear yard. The design is a self-created condition with no unique property-based circumstance supporting the variance. The front yard setback is relatively standard, (the home is not located deep into the lot), the lot depth isn’t shallow and the rear lot line isn’t at an angle, so no physical unique challenges are identified supporting a rear yard setback variance. 3) Will the variance alter the essential character of the neighborhood? Building coverage is treated the same throughout all neighborhoods in Edina. Lots greater than 9,000 square feet are allowed up to 25% building coverage and lots less than 9,000 square feet are allowed up to 30% building coverage. Each property in the neighborhood is expected to meet this requirement. Staff often hears from residents that projects appear to be over-built and massive even under the current code. Lot coverage and massing are issues continually raised when discussing “neighborhood character” with less massing and coverage the preference of residents. Recommended Action: Staff cannot support the variances requested for rear yard setback and to exceed the 25% building coverage requirement at 6601 Biscayne Blvd. It is especially difficult for staff to support or recommend approval of a variance from the code to exceed the building coverage requirement. Staff doesn’t believe there are unique circumstances to the subject property. Staff’s recommendation for denial of the requested variance is based on the following findings: Historically staff has not recommended approval of lot coverage variances based on all lot coverage requirements being calculated the same on all single-family residential lots. STAFF REPORT Page 4 Variances must be based on the unique characteristics of a lot and not on an owner’s use of the property. Approving the variances sets a precedent that could affect surrounding properties and neighborhoods with similar lot size and configurations. Deadline for a city decision August 5, 2021.

The purpose is to allow enjoyment of their back yard from the upper level without relying on stairs, as the owners (aged 70 and 72) intend to age-in-place. This application is for two variances to Edina Zoning Code: LOT COVERAGE: An increase of 1.5% over the allowed 25% lot coverage (Current lot coverage is 29.2% so this project would be a net reduction to 26.5%). REAR YARD SETBACK: Principal Buildings have a 25-foot minimum. Decks have a 5-foot minimum. For this covered deck, we are asking for a 9-foot deviation between the required and provided setback (16 feet from the property line) We believe that a granted variance will: A. Relieve practical difficulties. REGARDING LOT COVERAGE: 1. The proposed use is reasonable but there are difficulties in complying with the code, including functional and aesthetic concerns. 2. The current lot coverage is 29.2%, due to the rambler (1-story) style. Because of this style of low- slung home, main-floor additions for “one-level living” are technically prohibited, even though the home has very modest proportions compared to others in the neighborhood. 3. The sloping yard is not accessible for lesser-abled people. Please find the attached supporting documents: i) Owner Statement of home alterations to facilitate Aging in Place. ii) ‘Section Diagram Grade Change’: illustrating lack of accessibility to yard for lesser-abled people. iii) Comparative ADA accessibility requirements (slope) for accommodating people with low mobility. iv) Research supporting the importance of access to the outdoors. v) Excerpts from Edina’s Comprehensive Plan, Chapter 4 ’Housing’ acknowledging the need to be flexible to accommodate the aging demographic that is currently under-served. vi) Excerpts from Edina’s Comprehensive Plan, Chapter 12 ‘Community Health’ demonstrating Edina’s commitment to their aging demographic. Page 2 of 4 REGARDING REAR SETBACK 1. The house was built before the 25% lot coverage rule had been adopted. The rambler does facilitate one-level living, however, it does not allow room for a covered outdoor space. 2. Recognizing a large discrepancy between the 5’ setback for Decks, and the 25’ setback for a Screened Porch (both fall under ‘Principal Building’), we believe that it is in keeping with the integrity of the neighborhood to have an intermediate point between the two. The proposed Porch is 16.5’ away at its corner point and doesn’t reach its full width until 23’ from the property line. We think this holds a beautiful proportion and suitable intermediary between the 5’ Deck setback and the 25’ house setback. 3. Being a corner property with more restrictive setbacks, the lot has a more limited construction area than its neighbors, with a “dual front yard setback” common to a corner lot. B. Correct extraordinary circumstances applicable to this property but not applicable to other property in the vicinity or zoning district REGARDING LOT COVERAGE AND REAR SETBACK: 1. One-story “ramblers” are part of the identity of Edina, especially this fine example built by Carl Hanson. More and more of them get torn down every year, replaced by 2-story homes that may have a lesser “lot coverage” but are much more massive in scale. This existing home is very low- slung and unimposing, yet the particulars of the “lot coverage” calculation make it impossible to add-on to without a variance. This modest home would continue to be modest with this small addition of a screened porch. Variances are intended to accommodate projects that support the intent of comprehensive city plan, yet do not meet the numerical specifics of the zoning code. We doubt that neighbors would find this project at odds with larger city goals for development. If this variance is not granted, then the livability of the home will be compromised for these owners and make it more likely that the home would be sold, torn down and replaced with a bulkier building. C. Be in harmony with the general purposes and intent of the zoning ordinance. REGARDING LOT COVERAGE: 1. Aesthetic improvement/ modernizing exterior components i) See rendering images ii) Neighbor’s support of intended improvements; statements to be forthcoming 2. Diminishing likelihood of tear-down by means of increasing owner commitment to reside in current residence as long as possible, increasing property value thus making it less appealing for future tear-down purchase, and increasing live-ability to potential future families i) Owner’s statement indicating dedication & continued intent to maintain and improve property ii) Project value: $215,000 3. Willingness to surrender rights to future pool/tennis court via easement incorporated into title or other approved method. Page 3 of 4 4. Neighborhood bulk comparison as illustration of compatibility/ reasonableness REGARDING REAR SETBACK: Willingness to surrender rights to future pool/tennis court via easement incorporated into title or other approved method. – On the next page is shown the 4 adjoining properties at the corner of Biscayne and Londonderry, illustrating the proximity to site-lines and size of footprint allowed a pool, compared to the proposed off-ground structure (hatched) Page 4 of 4 D. Not alter the essential character of the neighborhood. REGARDING LOT COVERAGE & REAR SETBACK: 1. New covered deck & outdoor deck barely visible from the road i) See rendering images. 2. Diminishing likelihood of tear-down i) (See C-2) E. Additional considerations 1. Improvement of drainage on-site i) See Landscape plan 2. Reducing Lot-coverage percentage by means of this proposed outdoor space. i) See Survey and ‘Existing and Proposed Site Plans’ ii) Supporting images of prior Lot Coverage reduction by Owner. 3. Open Deck minimally sized to the 150 s.f. allowance number. Covered/ screened Deck at 382 s.f. is more valuable for elderly demographic by virtue of its protective components against the elements and nature.

We fell in love with the neighborhood in 1993 and committed ourselves to rehabilitating the existing low-slung structure. The home was in complete disrepair when we purchased it and we had to live in temporary housing for a few months while the home was made habitable. Since that date, we have been good stewards of our home. It is intended to be our forever home. We are thoroughly rooted here: Our children were raised here and went through the French Immersion program until they graduated high school. We constantly updated the house with attentive maintenance. The reason we are asking for this variance is clear: we would like to add an accessible covered deck which would allow us outdoor use of our property while aging in place. In the past ten years, we moved parents passed away since that time, but we saw the detrimental impact of moving at an advanced age. Now, with the pandemic, we have seen where they were locked down and isolated from their families. We began to discuss what it would take for us to continue to live in our home for as long as possible. Karen turns 72 this year and Russ turns 70. Clearly, aging in place with one floor living was the key. Due to our modifications, all of our basic needs (bedroom, bathroom, den and kitchen) are easily accessed in a wheelchair. (Karen was in a wheelchair for 10 months in 2010-11 following multiple leg surgeries.) We decided that adding a screened porch and replacing our deteriorating deck via main floor access would allow us to leverage our yard and neighborhood as our mobility decreases. The 382 sf screened outdoor space would allow us more protection from sun and mosquitos than the previous uncovered deck, ensuring that we would not feel locked in our home when we go into the next decade or two. This would be the capstone to having a home that would make us safe, happy, and add to our health for the foreseeable future. If such an -evaluate our capacity to age in place in this home. We understand that there are community standards and rules. We believe our modest proposed project does as much good for us personally as for the neighborhood as a whole. We would consider this proposed enclosed porch the crown jewel of our property; the attached documents should prove our commitment and willingness to forego other site components that could add to our property (such as patio, swimming pool, tennis court). We have been good citizens & are dedicated to the community. Russ was Treasurer for Normandale French Elementary. Later on, he became Chair of the Edina Arts and Culture Commission. Karen has been active in the Friends of the Edina Library and is almost a full time volunteer for several community groups. We have loved being an integral part of this neighborhood and hope to continue this for as long as possible. Thank you for your consideration and for giving us a chance to truly make this house our forever home.

We have seen their plans and this would enhance their property and our neighborhood. We fully support them in their request to proceed with their porch.

I have live there for about 20 years. The Rubin's were living in their house when we moved in. At the fence line between our two properties the Rubin's have a tall evergreen trees that offer a lot of privacy between the two properties. I have looked at their proposal to add a porch off the main level and a ground level deck. I think that these additions to their house would be great for the Rubin's without affecting my property in any way. When we moved in we added a four season porch and deck off of our main level which has added a lot of enjoyment to my family over the years. I support their proposal for a variance. They are reducing the building coverage ratio and the 9 ft variance for the rear yard set back will not change anything for the Joneses. The way it looks is that the porch is encroaching the rear set back, not the open decks so noise would not be any more of an issue. I look forward to see the addition built for the Rubin's. I'm sure their family will enjoy the new space just like Nancy and I have enjoyed our porch and deck.
