Correspondence - 2478 Black Lake Road - 6/5/2025 (5)Staging and Deliveries Re; 2478 Black Lake Rd. Spring Park Autumn Ridge Homes in an effort to help reduce frustrations due to the width of Black Lake Rd is proposing an outline of how we will stage deliveries of various materials to the site and parking for sub-contracted workers.We will be using the mall parking lot at Lake Shores Mall (see attached map) to stage material deliveries for the concrete, drywall and any extra sub -contractor vehicles. There are 3 homes that will be notified of time and dates of the con crete and span-crete deliveries. 2563 Blake Lake Rd. 2473 Black Lake Rd. 2486 Black Lake Rd. 2484 Black Lake Rd. 2473 Black Lake Rd. 2447 Black Lake Rd. 1st Month; Bollig excavating who has done work using Black Lake Rd for a prior project is aware of the difficulties of the road. Bollig will drop and walk in the equipment needed to perform the excavation work. The first task will be to create a parking area that will be the width of the lot (50’) and approx. 20’ deep with 2” clear limestone. The depth of the parking area will be increase to approx. 24’ once backfilling has occurred. Any excavation materials needed will be brought to the site and immediately dumped with the truck leaving the site.The portable toilet will be placed at the NE corner of the lot just off the street. The dumpster when needed will sit next to the portable toilet, the dumpster will not be needed until roof sheathing has been completed and will be loaded out and r emove. The dumpster will be returned for drywall scraping. The small amount of material generated between dumpste rs can be left in the house while work is being performed this way we can better utilize the parking for trucks and cars.

The dumpster will be returned for drywall scraping. The small amount of material generated between dumpste rs can be left in the house while work is being performed this way we can better utilize the parking for trucks and cars. Oscarman masonry will be performing the concrete work for the house. Oscarman has been notified that any vehicle that does not fit on the parking being provided will need to be parked at the mall and only 1 cement truck at a time will permitted to sit on the road while off loading it’s material. When it comes time to pump material to the footings we’ll need the parking area for the pump truck and 1 cement truck will need to sit on the road to off load its material. This task will take no longer than 45 minutes to perform and clean up will occur off site.The 6 neighboring houses will be notified 2 days prior to this happening and will be given an approx. time of day for this task so they can adjust their schedule so is not be blocked in or out. The second concrete task will be to drop forms for the walls, this truck will be able to utilize the parking area. The third task will be to pour the walls and this will be another partial blocking of the road and will take approx. 1.5 hrs and since this occurs usually within 2 days of the footings the 6 neighbors will have this date already along with an approx.time of day for the task. There will be only 1 truck at a time off loading it’s materials and will perform clean up off site. The fourth concrete task will be picking up the forms and the truck can utilize the parking area. Bollig will then backfill and extend the depth of the parking area and clean up and sweep the road as needed. The lumber will be delivered to the site using a boom truck and will be able to utilize the parking a rea when off loading material.Deliveries will only be made between mid morning and mid afternoon as to avoid neighbor’s leaving or returning from work. During deliveries vehicles will be parked on Warren Ave. The carpentry crew consists of only 2 carpenters, 1 job trailer, and 1 bobcat. The bobcat will be dropped off and left at the site until framing has been completed and will be utilized to unload and move material as it’s delivered to the site. This house does have a span-crete garage with floor panels that will need to be delivered and set. This will occur the same way the concrete was staged. The crane will sit on the parking area and the truck with the floor panels will be off loaded and placed onto the foundation. This task should take no longer than 2 hrs. The 6 neighbors will be notified 2 days prior to this happening along with an approx. time. Once the panels have been set the carpenters can utilize this additional space for stocking the roof trusses and materials. Months 2-3 From this point on Autumn Ridge will only schedule 2 subs at a time so as to make sure there is enough off street parking provided for those subs to use. Shingles will be delivered with a boom truck which will sit on the parking area along with 1 vehicle while off loading. Near the beginning of the third month the concrete for basement floor will need to be placed at which time we will be notifying the 6 homes 2 days prior to this happening. This task should take approx. 1.5 hrs to off load material and staging will occur at the mall. Near the end of the third month the upper garage will need to be placed, this will scheduled with no other subs at the site so the parking can be used for the crews truck and the cement truck can then back directly up to the garage opening to off load its material. Sheetrock delivery will use the mall parking to stage the sheetrock loads. The boomed truck can sit on the parking area and this will done when no other sub is at the site. From this point on the deliveries will be simple and quick drops. Autumn Ridge will continue to schedule sub-contractors 2 at a time for the remainder of the project. Months 4-5 The final partial road blockage will occur near the end and will involve the cement company again when they pour the concrete driveway and sidewalk. This will happen in the same manor with notifying the 6 neighbors 2 days prior with an approx. time of day and should only take 45 minutes. This project is expected to take approximately 5 months to complete starting in June and ending sometime in November. The president of Autumn Ridge Homes (Brian)lives and offices only 3 miles from the site and will be making multiple site visits per day to insure the road is kept free of debris and to also make sure there are not any problems with the parking area. All sub-contractors will be given a copy of this letter to ensure their understanding of the road and parking situation and that any violation of street parking will not be tolerated.Construction hours will follow city ordinance. Brian’s contact number is 763-269-2697. Our goal is to make this as painless as possible for everyone in the neighborhood. If a situation does occur please bring it to our attention so we can take appropriate actions. Sincerely, Brian Harju Each sub-contractor will need to sign and return this Autumn Ridge showing that have read and understand this proposal of actions.

I also include 3 more neighboring properties. I also attached 2 surveys, one clean one with the gutters and downspouts shown and one marked up showing the temp parking area along with gutters, landscape rock beds and lawn location. The survey does show 2 rows of silt fence along the lake side and we use bio rolls for the street side. The final landscape plan includes rock beds for the entire street side along with dry rock beds down both sides of the house up to the rear of the house. From there it will be grass. I designed the house with a hip roof and a eyebrow roof over the garage so I could use gutters all the way around the perimeter of the roof to control the run off and direction of the water flow. The stock piling of dirt will be at the rear corner of the foundation and will have 2 rows of silt fence between it and the lake. To date I've had over 2 dozen successful design/builds on lake Minnetonka with no issues what so ever with run off using this method. Please let me know if there is anything else.

These plans are required with all building construction due to the small lot sizes, limited street widths and proximity of adjoining homes. The Staging plan is intended to attempt to mitigate the nuisance issues associated with site construction for the surrounding neighborhood. 1. The Staging and deliveries narrative is quite comprehensive. The narrative states that they will provide a 60’x 20’ parking area extending from the street into the lot. The site plan “Before Demolition and Grading Begin notes indicate that a temporary rock construction entrance extending at least 50 feet from the street into the site. The narrative and site plan notes conflict. Applicant shall clarify which option will be pursued. The larger parking and service area outside of the street will reduce the traffic burden for neighboring properties. 2. The Staging and deliveries plan indicates they will notify the three neighboring homes of dates for deliveries and work at the site. In examining the Hennepin County GIS, I believe that 6 properties will be impacted by the traffic to this site and home construction. Notification shall be expanded to the 6 properties on both sides of the Black Lake Road nearest to the construction site. 3. Parking shall be limited to the on-site parking. The applicant shall demonstrate that the adequate parking exists when deliveries are being made. If construction crews /subcontractor vehicles exceed the available parking at the site. The plan must identify off-site parking options. 4. Work activities shall be limited to the hours of 7:00 a.m. to 8:00 p.m. on weekdays and 8:00 a.m. to 5:00 p.m. on weekends. Applicant shall provide notice of site deliveries 2 days prior to the event. The plan adequately addresses; site clean up, street clean-up, dust control and contact information. Construction Staging Site Plan. The applicant must provide a site plan that shows the following items to show they fit the lot. This information must be provided prior to issuing the building permit. 1. The location and extend of the proposed on-site parking/ loading areas. 2. Location of Trash dumpsters / roll offs. 3. Location of Biffs 4. Location of dirt stock piles. 5. Erosion and sedimentation devices. Site Plan review: The site is zoned R-1 Single and Two Family zoning district. 3 1. The single family home is a permitted use in the R-1 zoning district. 2. While the lot area (8869 sq. ft.) is below the minimum lot area standard, this lot of record is considered buildable because the lot has access to municipal utilities and the proposed building meet the required R-1 setbacks. 3. The proposed building meets all the R-1 required setbacks. 4. The proposed site plan exceeds the 30% hardcover standard for R-1 lots. Within the R-1 district residential development may have hardcover up to 40 % of lot area with provisions for on-site storm water treat before site drainage enters the lake. The applicants site plan identifies that the new plan reduces hardcover over the previous house. However, the previous home has be removed for over one year, as such any grandfathered rights to a legal nonconforming condition has expired. The current construction is subject to the current zoning standards. The city may approve hardcover over 30% of lot area and less than 40% of lot areas with an on-site storm water management plan that is approved by the City Engineer and the Watershed district. The on- site storm water measures may consist of the following; Iv .Measures to be taken for the treatment of stormwater runoff and/or prevention of stormwater from directly entering a public water. The measures may include, but not be limited to the following: (A) Installation of rain gardens, infiltration basins, or bio filtration basins should be considered for treatment of stormwater runoff from hard surfaces. Filtration basins should be considered if soil conditions are not favorable for infiltration. (B) Installation of erosion control devices, including silt fence, bio-rolls, erosion control blanket, and storm sewer inlet protection should be used. (C) Installation of oil-skimming devices and sump catch basins should be used to improve water quality. (D) Stormwater runoff from hard surfaces should be directed into pervious areas (grassed lawns or landscape beds) through site grading and use of gutters and downspouts. (E) Hard surfaces should be constructed using pervious pavement or pavers, or raised materials such as decking which has natural earth or other pervious material beneath or between the planking. (F) Grading and construction techniques should be implemented that encourage infiltration of stormwater runoff. (G) Installation of berms or basins should be considered to temporarily detain water before dispersing it into pervious area. The applicant may choose the measure to meet the storm water management conditions of the code. They may wish to contact the City Engineer to discuss options and what measure are most effective and least intrusive on the lot. Recommendation: Prior to issuance of the building permit the applicant must address the aforementioned issues of this email. Please have the applicant call me (Al Brixius @ 763-957-1100) if there are any questions regarding this correspondence. The city engineer is also reviewing this site plan and will provide comments.

He believes discussing the remaining items in-person will be the best way to resolve any remaining issues in a timely manner so that the application can move forward to the building permit application process. The City Planner did review your revised plans and provided comments below in red. Also our City Engineer’s comments regarding the storm water management plan are as follows: 1. Please provide details/description of the proposed rock garden areas. These areas will be required to allow for infiltration through the bed (permeable fabric versus plastic) or that area will need to be included in the Impervious calculations. 2. A stormwater management plan that accommodates the additional impervious from the site must be submitted for approval. 3. Please add the Lake 100-year high water elevation and Ordinary High Water Level o the survey/plan. 4. Please provide details for the proposed retaining walls. It appears that some of the walls may require structural designs and construction/grading on adjacent properties due to the proposed heights. Please provide details of the proposed construction. 5. Please complete and provide approvals for the necessary Minnehaha Creek Watershed District Permits, which may include Erosion Control, Floodplain Alteration, Shoreline and Streambank Stabilization, and Stormwater Management.

In examining the Hennepin County GIS, I believe that 6 properties will be impacted by the traffic to this site and home construction. Notification shall be expanded to the 6 properties on both sides of the Black Lake Road nearest to the construction site. The new narrative indicates that they will notify 5 adjoining neighbors of deliveries and work on the site. I recommend that the notify 6 neighbors along Black Lake Road. This recommendation is based on six lots that may be impact by construction traffic due to proximity and driveway location. 3. Parking shall be limited to the on-site parking. The applicant shall demonstrate that the adequate parking exists when deliveries are being made. If construction crews /subcontractor vehicles exceed the available parking at the site. The plan must identify off-site parking options. The temporary parking area will be 50’ x 24 ‘, the site plan shows that the dumpster (10’ x 20’) and the porta- potty will occupy the north 15’ of the parking area, leaving approximately 35’ of parking area for 2 carpenter vehicles, 1 job trailer and 1 bobcat. The parking area will be adequate except when the site deliveries are being made. Where will the carpentry crew vehicles and trailer be parked to free up the parking area for delivery trucks? We recognize that the deliveries will be scheduled, property owners will be notified and off- load will be a short event, but parking area must be available to allow the larger delivery vehicle to turn around and leave the site. Please address this issue. 4. Work activities shall be limited to the hours of 7:00 a.m. to 8:00 p.m. on weekdays and 8:00 a.m. to 5:00 p.m. on weekends. Applicant shall provide notice of site deliveries 2 days prior to the event. The times restrictions will be condition of building permit approval.

The applicant may choose the measure to meet the storm water management conditions of the code. They may wish to contact the City Engineer to discuss options and what measure are most effective and least intrusive on the lot. The storm water management plan must be approved by the City Engineer. In review of what they are suggesting I have the following comments and questions. 1. They have proposed using gutters around the house to capture and direct drainage away from adjoin lots. This is an excellent option. 2. They are proposing rock beds around the street side and side yards to direct drainage to the lake. I believe that the rock beds will not allow infiltration and would be counted as hard 5 cover. A single family lot cannot exceed 40% hardcover. Based on the applicant’s storm water plan it appear the house, driveway, and rock cover will comprise approximately 60% of the lot area. The City Engineer will need to comment on whether the rock beds are hardcover. 3. The roof, gutter and rock beds may increase the velocity of the storm water drainage to the lake, the plan does not provide any plan for retention or treatment other than erosion control during construction. 4. Hard cover may exceed 30% of lot area up to 40% of Lot area with a storm water management plan that prevents direct drainage into the lake. The code cited above outlines measures that may be implemented to receive approval of up to 40% hard cover for a single family lot. Recommendation: Prior to issuance of the building permit the applicant must address the aforementioned issues of this email. Please have the applicant call me (Al Brixius @ 763-957-1100) if there are any questions regarding this correspondence. The city engineer is also reviewing this site plan and will provide comments. Based on may review of the revised staging plan, approval of the staging plan and building permit will require the following: 1. Notice of deliveries and work will be given to six single family properties near the work site. 2. The developer identify the parking both on-site and off-site to accommodate peak activity times at the site (deliveries). See comments above. 3. Construction activities shall abide by the working hours noted above. 4. The City engineer and Watershed district shall approve the storm water management plan to allow hard cover over 30%, up to 40% of the lot area.

SCOPE OF WORK & LIMITATIONS: 1.Showing the length and direction of boundary lines of the legal description listed above. The scope of our services does not include determining what you own, which is a legal matter. Please check the legal description with your records or consult with competent legal counsel, if necessary, to make sure that it is correct and that any matters of record, such as easements, that you wish to be included on the survey have been shown. 2.Showing the location of observed existing improvements we deem necessary for the survey. 3.Setting survey markers or verifying existing survey markers to establish the corners of the property. 4.Showing and tabulating impervious surface coverage of the lot for your review and for the review of such governmental agencies that may have jurisdiction over these requirements to verify they are correctly shown before proceeding with construction. 5.Showing elevations on the site at selected locations to give some indication of the topography of the site. We have also provided a benchmark for your use in determining elevations for construction on this site. The elevations shown relate only to the benchmark provided on this survey. Use that benchmark and check at least one other feature shown on the survey when determining other elevations for use on this site or before beginning construction. 6.Note that all building dimensions and building tie dimensions to the property lines, are taken from the siding and or stucco of the building. 7.While we show a proposed location for this home or addition, we are not as familiar with your proposed plans as you, your architect, or the builder are. Review our proposed location of the improvements and proposed yard grades carefully to verify that they match your plans before construction begins. Also, we are not as familiar with local codes and minimum requirements as the local building and zoning officials in this community are. Be sure to show this survey to said officials, or any other officials that may have jurisdiction over the proposed improvements and obtain their approvals before beginning construction or planning improvements to the property. 8.While we show the building setback lines per the City of Spring Park web site, we suggest you show this survey to the appropriate city officials to be sure that the setback lines are shown correctly. Do this BEFORE you use this survey to design anything for this site. STANDARD SYMBOLS & CONVENTIONS: "භ" Denotes iron survey marker, set, unless otherwise noted.

Sediment controls may be removed to accommodate short term construction activity but must be replaced before the next rain. x A temporary rock construction entrance shall be established at each access point to the site and a 6 inch layer of 1 to 2 inch rock extending at least 50 feet from the street into the site and shall be underlain with permeable geotextile fabric. The entrance shall be maintained during construction by top dressing or washing to prevent tracking or flow of sediments onto public streets, walks or alleys. Potential entrances that are not so protected shall be closed by fencing to prevent unprotected exit from the site. x Contractor shall install inlet protection on all existing storm sewer inlets in accordance with the city standard details. Inlet protection shall also be provided on all proposed storm sewer inlets immediately following construction of the inlet. Inlet protection must be installed in a manner that will not impound water for extended periods of time or in a manner that presents a hazard to vehicular or pedestrian traffic. DURING CONSTRUCTION: x When dirt stockpiles have been created, a double row of silt fence shall be placed to prevent escape of sediment laden runoff and if the piles or other disturbed areas are to remain in place for more than 14 days, they shall be seeded with Minnesota Department of Transportation Seed Mixture 22-111 at 100 lb/acre followed by covering with spray mulch. x A dumpster shall be placed on the site for prompt disposal of construction debris. These dumpsters shall be serviced regularly to prevent overflowing and blowing onto adjacent properties. Disposal of solid wastes from the site shall in accordance with Minnesota Pollution Control Agency requirements. x A separate container shall be placed for disposal of hazardous waste. Hazardous wastes shall be disposed of in accordance with MPCA requirements. x Concrete truck washout shall be in the plastic lined and dispose of washings as solid waste. x Sediment control devices shall be regularly inspected and after major rainfall events and shall be cleaned and repaired as necessary to provide downstream protection. x Streets and other public ways shall be inspected daily and if litter or soils has been deposited it shall promptly be removed. x If necessary, vehicles, that have mud on their wheels, shall be cleaned before exiting the site in the rock entrance areas x Moisture shall be applied to disturbed areas to control dust as needed. x Portable toilet facilities shall be placed on site for use by workers and shall be properly maintained. x If it becomes necessary to pump the excavation during construction, pump discharge shall be into the stockpile areas so that the double silt fence around these areas can filter the water before it leaves the site. x Temporary erosion control shall be installed no later than 14 days after the site is first disturbed and shall consist of broadcast seeding with Minnesota Department of Transportation Seed Mixture 22-111 at 100 lb/acre followed by covering with spray mulch. x Erosion control measures shown on the erosion control plan are the absolute minimum. The contractor shall install temporary earth dikes, sediment traps or basins and additional silt fencing as deemed necessary to control erosion. SITE WORK COMPLETION: x :KHQILQDOJUDGLQJKDVEHHQFRPSOHWHGEXWEHIRUHSODFHPHQWRIVHHGRUVRGDQ³DVEXLOW´ survey shall be done per Spring Park requirements to insure that grading was properly done. x When any remedial grading has been completed, sod or seeding shall be completed including any erosion control blankets for steep areas. x When turf is established, silt fence and inlet protection and other erosion control devices shall be disposed of and adjacent streets, alleys and walks shall be cleaned as needed to deliver a site that is erosion resistant and clean. x Contractor shall maintain positive drainage of a minimum 2% slope away from proposed building.

Ft. PERCENTAGE OF HARDCOVER TO LOT 36.5% STORMWATER MANAGEMENT NOTES: x All roof stormwater runoff shall be collected by gutters. Downspouts will direct stormwater towards swales on east and west side of proposed home. Swales shall route stormwater to rear and front yard, restricting flow onto neighboring properties. x Landscaping rock beds installed on east and west side of proposed home will reduce velocity of runoff. Rock beds shall not be lined with plastic, which will allow for infiltration/retention of stormwater. x A grass buffer of minimum 50' is proposed between Lake Minnetonka and all proposed hardcover surfaces. The grass buffer will help filter stormwater runoff.
