TO: Peter Vickerman - City Planner

FROM: Kelly E. Matzke - Arbor Committee Staff Liaison

DATE: November 14,2016

SUBJECT: The Reserve Arbor Lakes Landscape Review

The Arbor Committee reviewed the landscape plan for The Reserve Arbor Lakes at their meeting on November 10, 2016, and made the following comments:

The total number of overstory trees on the landscape plan is 140. The required landscaping ordinance states that not more than twenty percent of the required number of overstory trees shall be composed of one species. In order to be in compliance with the required landscaping ordinance, the total amount of overstory trees cannot exceed 28. The current landscape plan shows a total of 33 Norway Spruce, therefore, the amount should be reduced by at least 5 and replaced with trees of another species.

Autumn Blaze Maple trees are overplanted in the City of Maple Grove. The Arbor Committee recommends replacing Autumn Blaze Maple trees with something of a different variety from the recommended tree list created by the Arbor Committee.

FROM:

DATE:

SUBJECT: The Reserve Arbor Lakes - PUD Amendment and Development Stage Plan Review / The.Village at Arbor Lakes 2nd Addition Preliminary and Final Plat

After reviewing the above-mentioned submittal, the Park & Recreation Board staff has the following comments:

• The Park Dedication ordinance applies to this subdivision which requires a land dedication or a cash equivalent per unit based on the current rate.

~. The Park Dedication obligation for the proposed subdivision would be a cash dedication based on the 2016 Residential Multi - Dwelling rate of $3, 194 per unit. Fees will apply to all units.

• Based on the proposed 257 units the park dedication would calculate as:

257 units x $3,194 = $820,858

• The Reserve Arbor Lakes is located within the city's Park Service Area 24. Residents of this subdivision are currently served by the Central Park and Town Green complex located just west of the proposed subdivision in Park Service Area 23. Future park development is anticipated in PSA 24 as further development of the area occurs.

General • The recommendations above are that of the Parks and Recreation staff. Park dedication

requirements are acted on by the Parks and Recreation Board at their regularly scheduled monthly meetings and forwarded on to the City Council for final approval.

• Applicants may pay the park dedication fee at any time after the final plat has been approved by the City Council and Park Board but it must be paid before the plat is released by the City forfiling.

• Park dedication rates are reviewed annually in February by the City Council. The rate is applied at the time the plat is released to the County for filing.

November 13, 2015 Fire Department Site Plan Review The Village at Arbor Lakes

A site plan review has been conducted for this project. The following items need clarification or need to be revised to meet code requirements.

1. Water Supply

Fire sprinkler water mains must be brought into a one-hour fire resistive room and must have exterior access, a drain, an emergency light pack, and a sidewalk to the public way. If the water main enters into a basement level the main may be extended to the first floor into a one-hour fire resistive room with the above requirements. In lieu of the one-hour fire resistive room one of the following options may be provided:

a. A yard post indicator valve must be downstream from the domestic (at the point where the domestic and fire split, on the fire side) or provide a separate fire main. A gate valve shall be installed on the domestic side.

b. A wall post indicator valve. Yard post indicator valves and wall post indicator valves must meet requirements ofNFPA 24. Yard post indicator valves shall be located not less than 40 feet from the building. Exception: When post indicator valves cannot be placed at this distance, they shall be permitted to be located closer, or wall post indicator valves used, provided they are in locations by blank walls or located diagonally at a comer of the building were the possibility of injury by falling walls is unlikely and from which people are not likely to be driven away by smoke or heat. Installation shall be in accordance with NFP A 24. Maple Grove City Code, Chapter 18, Article III, Fire Prevention Code, FPB-Policy 3

A. The eight inch combination water supply enters Building A on the east side. The plans indicate the water main is entering into the garage which is under a green area. The garage area does not show an area or room for this. A sprinkler room is shown at Q-5/6 on the plan.

B. The water main should not be run under the building. NFPA, Section 8-3.1

C. By using a combination water service line with the high water usage in this building with 249 units, there will be a requirement to provide an electric solenoid valve to shut down domestic in

"Serving Today, Shaping Tomorrow" AN EQUAL OPPORTUNITY EMPLOYER

November 12,2015 Fire Department Site Plan Review The Village at Arbor Lakes Page Two

the event of a fire sprinkler activation. The solenoid valve is required when the maximum size of domestic water on combination fire sprinkler/domestic water line in the building exceeds Yt size of the water supply line.

It would be an advantage to provide a separate fire main into the building to avoid domestic water usage problems interfering with the fire sprinkler system. Maple Grove City Code, Chapter 18, Article 1 II, Fire Prevention Code, FPB- Policy 3.

D. Water supply/fire mains were not reviewed for future Buildings B, C, D, and the entire Commercial area as utility plans were not provided.

2. Fire Hydrants

Section 508.5.1 of the 2003 Minnesota State Fire Code is hereby amended by adding the following language: Where a portion of the facility or building hereafter constructed or moved into or within the jurisdiction is more than 150 feet from a hydrant on a fire apparatus road, as measured by an approved route around the exterior of the facility or building, on site fire hydrants and mains shall be provided where required by the code official. Maple Grove City Code, Chapter 18, Article III, Fire Prevention Code, Sec. 18-81.

A. The fire hydrant located at the south side of Building A at the southwest comer and east of the clubhouse is 30 feet from the building. Hydrants and valves shall not be located closer than 40 feet from the building. If the fire hydrant is located straight out from a comer of the building, it is outside of the collapse zone and may be closer. NFPA 14, Section 3-13.2

B. A fire hydrant shall be located within 150 feet of the fire department connection and shall be approved. NFPA 14, Section 6-3.5.4.

This will apply to all buildings including the Clubhouse and Commercial area buildings. If the fire hydrant can be placed strategically it can be used for both Building A and the Clubhouse.

C. The fire hydrant located on the east side of Building A is across from the driveway into the parking garage. It will probably cause problems to have a fire truck hooked up to a fire hydrant in this location and have the possibility of vehicles leaving the building via this location. Please move the fire hydrant feet ~30 feet to the north.

D. Hydrants shall be located within a reasonable distance from driving surface; five feet minimum from curb (fire department access). If hydrant is located in a safety island and cannot be located back five (5) feet from the curb, the hydrant shall be centered in the safety island. It is the fire department's preference to locate a fire hydrant along the driveway entrance, unless only one fire


November 12,2015 Fire Department Site Plan Review The Village at Arbor Lakes Page Three

hydrant is being installed and needs to be located closer to the fire department connection. NFP A 14, Section 3-13.1

E. Fire hydrants and locations of hydrants were not reviewed for future Buildings B, C, D, and the entire Commercial area as utility plans were not provided.

3. Fire Department Apparatus Access Roads

Approved fire apparatus access roads shall be provided for every facility, building, or portion of a building hereafter constructed or moved into or within the jurisdiction. The fire apparatus access road shall extend to within 150 feet of all portions of the facility or any portion of the exterior wall of the first story of the building as measured by an approved route around the exterior of the building.

Design: Fire apparatus roads shall be designed to a 20 foot width and maintained to support the imposed loads of fire apparatus (7 ton) and shall be provided with a surface so as to provide all-weather driving capabilities.

Longitudinal grade shall not exceed 6 percent or lateral grade shall not exceed 2 percent. Both grades shall not be used together. Fire apparatus access roads shall be a minimum of 30 feet and a maximum of 80 feet from buildings and shall be positioned parallel to the side of the building.

A 20-foot inside and a 40-foot outside turning radius shall be provided for fire apparatus access and approved turnarounds. (The City of Maple Grove allows gravel fire apparatus roads that are used solely for fire apparatus roads.) Maple Grove City Code, Chapter 18, Article III, Policy FPB-4

A. There is a dead end roadway at the southwest end of Building A. It measures ~290 feet long. Acceptable tum-around alternatives shall be used when fire apparatus access roads have a dead end greater than 150 feet.

B. South side of Building A north of the Clubhouse does not have fire department access. There is ~560 feet of building area without access.

C. East side of Building A. The u-shaped green area above the parking garage with three open sides is ~ 270 feet from the fire department access roadway. The fire apparatus access road shall extend to within 150 feet of all portions of the facility or any portion of the exterior wall of the first story of the building.

D. Tunnels to all apartment buildings must be able to support the weight of fire department fire apparatus.


November 12, 2015 Fire Department Site Plan Review The Village at Arbor Lakes Page Four

E. The resident bridge from Building A to Building 0 must meet height clearance (13' 6") for fire department fire apparatus. MSFC Section 503.2

F. The fire access roadway shown on the east sides of future Building C and future Building D is within 20 feet of the buildings in some areas. Fire apparatus access roads shall be a minimum of 30 feet and a maximum of 80 feet from the buildings and shall be positioned parallel to the side of the building.

G. The access roadway in #6 above ends at Hemlock Lane with a sharp turn to the north and does not meet minimum turning radius.

H. The access roadway in # 6 above does not meet turning radius where it joins the private roadway at the northeast and southeast comers of Building A.

I. The access roadway in #6 above has multiple trees that indicate they will impede within the roadway when mature.

J. The north driveway entrance into Building A parking lot does not meet minimum turning radius.

K. Building B at the west entrance to the parking lot does not meet minimum turning radius.

L. Building B access is not possible for fire department apparatus because of the fenced area. Approximately 510 feet of the building which is parallel to Arbor Lakes Parkway and Hemlock Lane are not accessible.

M. Both entrances to Building C parking lot do not meet minimum turning radius.

N. Building C access is not possible for fire department apparatus because of the fenced area. Approximately 350 feet of area is not accessible on the south and west sides.

o. Building D access is not possible for fire department apparatus because of the fenced area. Approximately 100 feet is beyond the minimum 150 feet on the northwest side that is parallel to Hemlock Lane.

P. Commercial area south of Arbor Lakes Parkway must meet minimum turning radius throughout.

Q. Lot 5, Block One will require fire department apparatus access within 150 feet of all portions of the facility or any portion of the exterior wall of the first story of the building if this is a hotel or senior housing.

The following comments that are checked need to be resubmitted on your site plan for fire code review.

I} 0 Utilities: All utilities to be shown on plan including existing water mains/type/size, existing fire hydrants, proposed watermains/type/size, proposed fire hydrants, and all valves. 2003 Minnesota State Fire Code (MSFC), Section 501.3

2} 0 Water Supplies For Fire Protection: Section 508.5.1 ofthe 2003 Minnesota State Fire Code is hereby amended by adding the following language: Where a portion of the facility or building hereafter constructed or moved into or within the jurisdiction is more than 150 feet from a hydrant on a fire apparatus road, as measured by an approved route around the exterior of the facility or building, on site fire hydrants and mains shall be provided where required by the code official.

a. For buildings equipped throughout with an approved fire sprinkler system installed in accordance with NFP A 13 or NFP A 13R, the distance requirement shall be one fire hydrant within 150 feet of the fire department connection and 600 feet for all other fire hydrants.

b. In buildings with high piled combustible storage or buildings that are inherently hazardous in nature because of hazardous to life (large number of people, people sleep in building), hazardous processes or which store, use, or handle flammable, combustible or hazardous materials, additional fire hydrants may be required by the code official. Maple Grove City Code, Chapter 18, Article III, Fire Prevention Code, Sec. 18-81.

3} 0 Number of Fire Hydrants: Appendix C, Section CI03.1 of the 2003 Minnesota State Fire Code is hereby amended by adding the following language: Number of Fire Hydrants. The minimum number of fire hydrants available to a building shall not be less than that listed in Table C 1 05.1 unless the required fire flow can be obtained from fewer hydrants. This fire flow shall be demonstrated using flow-testing procedures as approved by the Fire Marshal. The number of fire hydrants available to a complex or subdivision shall not be less than that determined by spacing requirements listed in Table CI05.1 when applied to fire apparatus access roads and perimeter public streets from which fire operations could be conducted.

4} 0 Considerations of Existing Fire Hydrants: Appendix C, Section C104.1 of the 2003 Minnesota State Fire Code is hereby amended by adding the following language: Existing fire hydrants on public streets are allowed to be considered as available. Existing fire hydrants on adjacent properties shall not be considered available unless fire apparatus access roads extend between properties and easements are established to prevent obstruction of such roads. Hydrants on public streets must be on the same side of the street to be considered as available. Sec. 18-84. The location, number, and type of fire hydrants connected to a water supply capable of delivering the required fire flow shall be provided on the public street fronting the property or on the site of the

7} 0 Fire sprinkler water mains must be brought into a one-hour fire resistive room and must have exterior access, a drain, an emergency light pack, and a sidewalk to the public way. If the water main enters into a basement level the main may be extended to the first floor into a one-hour fire resistive room with the above requirements. In lieu of the one-hour fire resistive room one ofthe following options may be provided:

A. A yard post indicator valve must be down stream from the domestic (at the point where the domestic and fire split, on the fire side) or provide a separate fire main. A gate valve shall be installed on the domestic side.

B. A wall post indicator valve

Yard post indicator valves and wall post indicator valves must meet requirements ofNFPA 24. Yard post indicator valves shall be located not less than 40 feet from the building. Exception: When post indicator valves cannot be placed at this distance, they shall be permitted to be located closer, or wall post indicator valves used, provided they are in locations by blank walls or located diagonally at a comer of the building


were the possibility of injury by falling walls is unlikely and from which people are not likely to be driven away by smoke or heat. Installation shall be in accordance with NFP A 24. Maple Grove City Code, Chapter 18, Article III, Fire Prevention Code, FPB-Policy 3.

Note: The City of Maple Grove does not provide water flow information. When this project is sent out for bidding by sprinkler contractors, they are required to design from current water flow information (water flow test). It would be beneficial for all parties involved ifthis information was included in the information supplied to the sprinkler contractors for bidding. The City of Maple Grove does not want to conduct numerous water flow tests for the same project.

8} 0 Looped Water Service Lines: The combination domestic/fire line serving the fire protection system should be a looped line for increased reliability and improved hydraulics. Loop systems should be sectionalized by placing valves at branches and at strategic locations to minimize the extent of impairments. A minimum oftwo independent connection points should be made in case of a problem with one, domestic and fire protection will not be severed. NFPA 24, Section 2-2.1 & A-2-2.3

9} 0 Minimum Requirements of NFP A 24: NFP A 24, establishes the minimum requirements for the installation of private fire service mains and their appurtenances supplying automatic sprinkler systems, water spray fixed systems, foam systems, private hydrants, and standpipe systems with references to water supplies, and private hydrants. The standard also applies to "combined service mains" used to carry water for both fire service and other use.

Chapter 2 has a specific requirement that mains be no smaller than six inch. Nothing in this standard as in other codes is intended to restrict new technologies or alternate arrangements, providing the level of safety prescribed by the standard is not lowered. Any alternate requirements will require written documentation substantiating that required fire flow can be achieved.

Hello Erik-

I have finished reviewing the plans for The Reserve at Arbor Lakes, and also discussed them with Mark Nelson in Utilities. Here are our comments:

Tunnels: Based on my conversation with you, the utilities under the tunnels are being installed to proper depth to accommodate the tunnel. And, you have stated that these tunnels will be finished and climate controlled. Thus, insulation will not be required for the utilities, but we do believe that the utilities should be in casing pipes under the tunnels. If anyone has to go and get them, the tunnel replacement will be expensive.

Storm Sewer Plan: These are private, so the following are recommendations only, based on our experience maintaining similar systems.

1- We recommend a minimum of is-inch diameter for ease of jetting. Also, we recommend RCP under all street crossings, as you have shown on the main entry north of the roundabout.

2 - There appears to be an unnecessary pipe run from the middle CB on the main entry north of the roundabout (CB # is currently IIXX", and RE = 908.25). Given the larger pipe size to the south, we recommend draining this CB to the south and eliminating the pipe to the north.

3 - How does the plaza north of the clubhouse drain? There is a network of inlets and pipes around the perimeter of Building 1 and Clubhouse, which whould work well. Plaze area between the two is flat (as desired, I believe), so I don't see a way for this to drain.

4 - CB 102-C4 (near SE end of Building 1) is in the middle of a driveway. Driveway might be temporary in nature, so please confirm where this CB will be ultimately.

Last, please adhere to all City building code requirements for pipe sizes and materials on the water and sanitary services, which information I presume will be submitted with the building permit application.

Thanks,

Mr. Peter Vickerman City Planner City of Maple Grove 12800 Arbor Lakes Parkway Maple Grove, MN 55311-6180

RE: The Reserve Arbor Lakes Maple Grove, Minnesota Site Plan Review Comments Response to Site Plan Review Comments dated November 2, 2016

Dear Mr. Vickerman,

On behalf of our client, Doran Development, LLC., we respectfully submit our response to Community Development comments provide in an email provided from you, dated November 2, 2016, along with the Engineering comments provided in an email from Jupe Hale, dated November 8, 2016. Our responses to the comments are as follows:

Planning Comments:

1. Staff is concerned about the number of parking spaces proposed. The plan shows 114 surface per bedroom. During the original Development Stage approval staff presented evidence that a standard of 1 space per bedroom was used in other communities and the Council was comfortable with this standard for the residential in this development. Please revise the plan to show additional parki ng spaces. It is not clear if there are proposed parallel parking spots on the far east side. If these are, please stripe them so that a clear count can be made.

Response: The surface parking has been revised to bring the total parking count to 393 stalls. The parkinq stalls on the far east side of the building are parallel parking stalls.

2. Previous plans had the sidewalk on the east side of the entrance drive which would allow better pedestrian access to the retail area to the south (since Arbor Lakes Parkway will not be extended east for some time.) Staff recommends that either the sidewalk be moved back to the east side or have sidewalks on both sides of the entrance drive.

The Village at Arbor Lakes November 8, 2016 Page 2

Response: The entry design intent is anchored with two rows of mapte trees in a symmetricat attey as you drive up the main entry. The sidewalk on the west side of the entry is a better fit in the space as it provides more space for the trees. Moving the sidewalk, or adding and additional sidewalk along the east side of the entry compromises the design intent of the entry and moves the trees further east which compromises the design intent of the future buildings, perimeter drives and parking. Maintaining generous space between the sidewalk, the tree and fence are imperative. It is our professional opinion that the sidewalk location is the best compromise between spaces, tree health, the design intent and pedestrian access. Pedestrian have a safe location to cross the entry drive at the crosswalk north of the roundabout if they so choose.

3. There are areas where the fence around the play lot shows up overlapping the building or paralleling in close proximity to the building. Would it make more sense to just bring the fence up the building and use the building wall as part of the enclosure rather than doubling up the fence?

Response: Please see revised plan. There are some utilities enteri'ng the building in that area and we want to separate children from those areas of the property. We are finalizing the design of the clubhouse and when that is done we will layout the play fence ill that fashion.

4. Please add fire department standpipes and hydrants to the hardscape and landscape plans so we can evaluate any conflicts.

Response: Standpipes and hydrants have been added to the landscape plans and the plans have reviewed been reviewed for conflicts.

5. Please provide details on all items in the hardscape plans including 5' aluminum fence, 3' play lot fence, etc, with clear numbering to indicate which detail goes with which feature on the plan.

Response: Fence details are shown on plan sheet L4.01. The same model of fencing will be used for all fencing throughout the site, which comes in both 3 and 5-foot heights.

6. Show the Gas Fi re Pit 1-19 on the plans. There is an arrow poi nti ng to where it to be located but no sense of size.

Response: The fire pits have been added to the plan as requested. They are 36" in diameter. A detail of the fire pit is shown on plan sheet L4.02.

7. Add seed symbol to the Landscape schedules and use a consistent shading pattern for the sodded areas.

Response: The sod symbol has been modified to match the sod hatch in the legend key.

8. Fill in all tree totals on LtO and make sure to limit overstory trees to no more than 20% of one species.

Response: Tree totals have been added and no overstory tree exceeds 20% of the total.

9. Show a master tree schedule for overstory and evergreen trees on LtO.

Response: A master schedule has been placed on plan sheet L4.03 due to size constraints of the table.

10. All trees shall be identified with its initial and number in a grouping on the plan sheets.

Response: All plantings have been labeled accordingly.

11. Many trees are hard to see because of the shading on our large format plans. Please review all Landscape Plans and darken trees accordingly. The PDF's and reduced sets are fine so there is something amiss with the large format printer (this seemed to happen with the initial sets as well where line work was missing or very faint.) Specific species where it is apparent are Norway Spruce, Sienna Glen Maples, Boulevard Lindens, Black Hills Spruce.

Response: The tree symbols have been revised accordingly.

12. The Norway Spruce on L2.02 appear to be near the play lot but are symbolized very small and likely won't fit in the space provided. Another plant species should be used here.

Response: The Norway Spruce specified is the Dwarf 'Cupressina' variety which grows 6-8 feet in width. The plant schedule has been revised to identify the common name as 'dwarf.

13. Tree Lilacs are considered ornamentals.

Response: The planting schedule has been revised accordingly.

14. I could only find 4 Sienna Maples and 6 Norway Spruce on L2.04.

Response: Sheet L2.04 has been revised accordingly.

15. The legend numbers weren't used on the plan.

Response: The plan sheets have been revised accordingly.

16. Landscape Notes should indicate boulevard areas must be irrigated.

Response: The Landscape Notes have been revised accordingly.

17. The architectural elevations are somewhat tricky to read and material samples would be helpful in getting a better understanding of what is proposed.

Response: Material samples have been provided as requested.

Engineering Comments:

1. Tunnels: Based on my conversation with you, the utilities under the tunnels are being installed to proper depth to accommodate the tunnel. And, you have stated that these tunnels will be finished and climate controlled. Thus, insulation will not be required for the utilities, but we do believe that the utilities should be in casing pipes under the tunnels. If anyone has to go and get them, the tunnel replacement will be expensive.

Response: Comment noted. We will discuss further with the Owner.

2. Storm Sewer Plan: These are private, so the following are recommendations only, based on our experience maintaining similar systems.

a. We recommend a minimum of 1S-inch diameter for ease of jetting. Also, we recommend Rep under all street crossings, as you have shown on the main entry north of the roundabout.

Response: Comment noted. We will take the City's recommendation under consideration and include where appropriate in forthcoming final building permit set.

b. There appears to be an unnecessary pipe run from the middle CB on the main entry north of the roundabout (CB # is currently "XX", and RE = 908.25). Given the larger pipe size to the south, we recommend draining this CB to the south and eliminating the pipe to the north

Response: The storm sewer in front of the main entrance is currently under final design changes due to the modified Clubhouse entrance. The storm sewer pipe referred to is drawn

incorrectly, as well as the one pipe crossing east over the east tunnel, and the storm sewer system between the tunnels and south of the Clubhouse will need to drain south to Arbor Lakes Parkway to avoid a direct conflict with top of the tunnels. The storm sewer stub, and related main lines, being installed by the City as part of the Arbor Lakes Parkway has the capacity for this modified storm sewer system. Final drainage calculations will be included with the forthcoming building permit set.

c. How does the plaza north of the clubhouse drain? There is a network of inlets and pipes around the perimeter of Building 1 and Clubhouse, which would work well. Plaza area between the two is flat (as desired, I believe), so I don't see a way for this to drain.

Response: Final Qirading and drainage plans for the pool courtyard will be included as part of the forthcomnq final permit set. The intent will be to provide a network of smaller area drains and yard inlets in a similar fashion to the Building #1 perimeter drains to assure sufficient drainage for thls relatively flat area. An 18" diameter storm sewer stub has been extended as shown from CBMH 102-C3· and sized appropriately for this area as well tributary roof downspouts from Sui~ldin9' 1 and the Clubhouse. Final drainage calculations will be included with the forthcominq buillding permit set.

d. CB 102-C4 (near SE end of Building 1) is in the middle of a driveway. Driveway might be temporary in nature, so please confirm where this CB will be ultimately.

Response: This catch basin will become a mirrored low point inlet to CBMH 102-C3. This portion of the temporary Fire Turnaround will be converted to barrier curb without a driveway at this location in current concept plans. Final drainage calculations will be included with the forthcoming building permit set.

3. Last, please adhere to all City building code requirements for pipe sizes and materials on the water and sanitary services, which information I presume will be submitted with the building permit application.

Response: Comment noted. All of these items will be properly addressed in the forthcoming building permit set.
