Box 147 Chanhassen, MN 55317 (952) 227-11 00 PRESENT ZONING: Highway and Business Services District, BH 2020 LAND USE PLAN: Parks and Open Space ACREAGE: 3.94 DENSITY: FAR. 0.18 SUMMARY OF REQUEST: The City is requesting subdivision approval to create two lots and one outlot at the end of West 79th Street. On one lot, a water treatment facility is being proposed. The second lot can either be sold or used by the City at a later date. The land use amendment would bring the existing zoning and proposed and potential future uses of the property into compliance with one another. The site plan approval is for the construction of the east water treatment plant with a variance from the setback to West 79th Street. LEVEL OF CITY DISCRETION IN DECISION-MAKING: The City's discretion in approving or denying a preliminary plat is limited to whether or not the proposed plat meets the standards outlined in the Subdivision Regulations and Zoning Ordinance. If it meets these standards, the City must approve the preliminary plat. This is a quasi-judicial decision. The City has a relatively high level of discretion in approving amendments because the City is acting in its legislative or policy making capacity. An amendment must be consistent with the City's Comprehensive Plan. The City's discretion in approving or denying a site plan is limited to whether or not the proposed project complies with Zoning Ordinance requirements. If it meets these standards, the City must then approve the site plan. This is a quasi-judicial decision. " " Location Map Water Treatment Plant Planning Case No. 05-12 ~ I-- f-.

Outlot A contains a parking area. Lot 1 is proposed for the East Water Treatment Plant. Lot 2 may be sold as a commercial property or used by the City at a later date. The property is zoned Highway and Business Services District, but is guided parks and open space in the City's comprehensive plan. In order to clarify the use of the site and make the land use consistent with the zoning of the property, the land is being re-guided to commercial use. The City is proposing a 12,500 square foot, one-story, 24-foot high water treatment facility with an 8,100 square-foot back wash tank. The building meets the setback from Highway 5 and West 79th Street. Building materials consist of a light brown brick, limestone colored block, beige concrete sill accent and glass block windows. The building elevations are highly articulated with many horizontal and vertical recesses and projections in the building façade. The roof consists of standing seam metal over the eastern end of the building, a flat roof in the central portions of the building, and a barrel metal roof over the loading dock area. A security system will be installed as part of the building construction. The extent of the security system is still being evaluated. The site is located on the eastern entrance to the City's downtown. The property becomes narrower from west to east going from a width at its widest of approximately 195 feet down to a width of 100 feet. North of the site is the Twin City and Western Railroad and West 78th Street and the end of West 79th Street. Highway 101 abuts the property to the east and Highway 5 abuts the property to the south. The old Hanus building is located west of the site. The Highway 5 pedestrian bridge intersects the western portion of the property, east of the proposed Water Treatment Plant building. The high point of the site is at the pedestrian bridge at an elevation of 978 and then slopes to the east, west and south. The low point on the property is in the southeast corner of the site at an elevation of 940. Trees are scattered on the property with no significant natural stands. A large grouping of pines is located in the southwest corner of the site, which are proposed to be preserved. The proposed development complies with the City's zoning and subdivision ordinance with the variance for the setback to West 79th Street. Staff is recommending approval of the proposed development. BACKGROUND The site was previously owned by Apple Valley Red-E-Mix. In 1992, the City initiated the condemnation of the former Apple Valley Red-E-Mix parcel. In October 1993, Apple Valley Red- E-Mix vacated the property. In June 1995, the City finalized the purchase of the site. On April 4, 1983, the City approved a non-conforming use permit, a conditional use permit (#82- 4) and a variance to permit a washout system at the Apple Valley Red-E-Mix site. The eastern end of the site was previously owned and used for a Taco Shop. In October 1991, the City initiated the condemnation of the Taco Shop parcel in conjunction with the realignment of the Planning Commission Planning Case No. 05-12 April 5, 2005 Page 3 intersection of Highway 101 and West 78th Street. On May 21,1993, the City finalized the acquisition of the parcel. The pedestrian bridge was constructed over Highway 5 in 1995. APPLICABLE REGULATIONS Chapter 18, Subdivisions Chapter 20, Article II, Division 6, Site Plan Review Chapter 20, Article XVII, "BH" Highway and Business Services District Chapter 20, Article XXIII, Division 7, Design Standards for Commercial, Industrial and Office- Institutional Developments COMPREHENSIVE PLAN AMENDMENT The property is currently zoned Commercial, BH, but is guided for parks and open space. At one time, it was thought that this area would be used as a park-like, open space gateway to the City of Chanhassen. However, the site will serve the City as a water treatment facility site with an additional lot that could be sold for development or used by the City. Utility services are a permitted use in the BH district. The land use amendment will bring the comprehensive plan and potential use of the site into compliance with each other. GENERAL SITE PLAN/ARCHITECTURE ARCHITECTURAL COMPLIANCE Size Portion Placement The building entrance is located off West 79th Street. The building entrance is articulated with glass and accessed via a raised plaza. Material and Detail Building materials consist of high-quality materials including a light brown brick, limestone colored block, beige concrete sill accent and glass block windows. The building elevations are highly articulated with many horizontal and vertical recesses and projections in the building façade. Height and Roof Design Building height is one story at 24 feet. Pitched roof elements include both a sloped roof of metal standing seam and a metal barrel roof. Height is limited to two stories in the BH zoning district. Planning Commission Planning Case No. 05-12 April 5, 2005 Page 4 Facade Transparency 50 percent of the first floor elevation that is viewed by the public includes transparent windows and or doors. All other areas shall include landscaping material and architectural detailing and articulation. Site Furnishing Community features include landscaping, lighting, and access to the pedestrian bridge. The building has a raised plaza at its entrance. Loading Areas, Refuse Area, etc. Screening of service yards, and truck parking/loading areas cannot be accommodated due to the constraints of the site and the function of the building. Access to the site is limited to West 79th Street. Landscaping and Tree Preservation The landscape plan for the water treatment plant has been developed to reflect the natural materials used in the building. Native trees, shrubs, and grasses as well as non-native perennials and shrubs have been utilized to create a naturalized planting plan. The guiding factors for selection and placement were attractiveness and low-maintenance. Bufferyard requirements: Required Proposed Highway 5 3 canopy trees 3 canopy bufferyard B - 250' 5 understory trees 23 understory 5 shrubs o shrubs North property line 3 canopy trees 7 canopy bufferyard B - 250' 5 understory trees 6 understory 5 shrubs 40+ shrubs East property line. o canopy tree o canopy trees bufferyard A-ISO' 2 understory trees 7 understory 2 shrubs o shrubs West property line 2 canopy trees 1 canopy bufferyard A - 175' 2 understory trees 10 understory 4 shrubs 40+ shrubs Where bufferyard requirements have not been met, existing vegetation, elevation change and/or distance makes up for the minimum requirements. Existing trees on the site include spruce, Austrian pine, and maple. Some of the maples may be able to be transplanted to another site. Staff will inspect the trees and mark ones that can be Planning Commission Planning Case No. 05-12 April 5, 2005 Page 5 moved. Once the ground has thawed, staff will coordinate the move. The Austrian pines along Highway 5 provide an excellent buffer for the plant and neighboring building and cell tower base. Staff recommends that as many as possible of these trees be saved. Trees lost due to construction will be replaced. There is a large expanse of grass over the underground tanks. The current proposal includes sod to be installed. Staff would like to explore the possibility of installing a planting of native grasses or other ground cover that would alleviate the need for mowing. City staff and the consultant will determine whether of not a shorter prairie grass or low ground cover would be suitable in this area. Currently, there is a naturalized area along the slope leading down to Highway 5. Staff is recommending that this feature remain in order to eliminate maintenance requirements in this steep area. Staff recommends that, where feasible, sod be replaced by grass seed. Exceptions would include along the curb line, trails and adjacent to the building. Lot Frontage and Parking location The property fronts on both Highway 5 and West 79th Street. Site access and parking are provided off West 79th street. Parking is provided off West 79th Street. COMPLIANCE TABLE (Water Treatment Plant) Code Pro osed Front setback 25' 33' Side Setback Rear Setback Building Rei t 10' 20' 2-sto 13' NA I-sto Site Covera e 65% 46% SUBDIVISION REVIEW GRADING, DRAINAGE & EROSION CONTROL The existing site ranges from a high elevation of 978 in the west central portion of the site down to a low point of 940 in the southeast corner. The plans propose to grade about 60% of the site for a water treatment plant, a proposed street with a cul-de-sac, and a stormwater pond. While the finished floor elevation of the treatment plan is set at 969.0, the site cannot be graded down to this elevation because of the existing pedestrian bridge. The applicant has done a nice job of working with this constraint and matching into the existing 978 elevation along the east side of the building. Because of the need to hold the 978 ground elevation near the pedestrian bridge, a retaining wall (6' - 10') will be required along the north side of the backwash tanks adjacent to the south side of the street and trail. This retaining wall will require a building permit from the City's Building Department. Planning Commission Planning Case No. 05-12 April 5, 2005 Page 6 The existing site drainage is encompassed within two different drainage areas. Under existing conditions, the westernmost portion of the site drains off site to the west while the remainder of the site drains to an existing storm sewer culvert in the southeast corner of the site. Under developed conditions, the applicant is proposing to capture the eastern half of the street drainage, all of the Lot 2 drainage and a large majority of the Lot 1 drainage. This stormwater will be conveyed via storm sewer and overland flow to the proposed pond in the southeasterly corner of the site for treatment. The remaining impervious surface from the street and treatment plant will drain to ane existing storm sewer in West 79th Street, which flows to an existing pond in the downtown area. The proposed pond must be designed to National Urban Runoff Program (NURP) standards with maximum 3:1 side slopes and a 10:1 safety bench at the NWL. An outlet control structure, per City Detail Plate No. 3109, must be installed at the outlet of the pond. Drainage calculations for the site have been submitted and only minor changes remain. The applicant is required to meet the existing site runoff rates for the lO-year and 100-year, 24-hour storm events. Storm sewer sizing calculations must be submitted prior to final plat application. The storm sewer must be sized for a lO-year, 24-hour storm event. Drainage and utility easements must be dedicated on the final plat over the public storm drainage system including ponds, drainage swales, and wetlands up to the 100-year flood level. Proposed erosion control must be developed in accordance with the City's Best Management Practice Handbook (BMPH). Staff recommends that Type I silt fence be used along the entire south and west construction limits. A rock construction entrance, per City Detail Plate No. 5301, must be added to the plans off of existing West 79th Street. In addition, tree preservation fencing must be installed at the limits of tree removal. All disturbed areas, as a result of construction, must be seeded and mulched or sodded immediately after grading to minimize erosion. Any off- site grading will require an easement from the appropriate property owner. Wetlands No jurisdictional wetlands exist on-site. Storm Water Management The City's Surface Water Management Plan shows a regional storm water facility on this property (RM-P5.2). The Riley-Purgatory-Bluff Creek Watershed District is currently designing stormwater-related improvements within the Rice Marsh Lake subwatershed. Preliminary discussions with the watershed district have suggested construction of a small regional stormwater pond on this site. The applicant should work with the watershed district to provide regional water quality infrastructure on this site. The flow path and velocity of the water from the flared end sections to the storm water should be evaluated. Erosion of the area is a concern as the water flows over the site into the pond. A Storm Water Pollution Prevention Plan (SWPPP) encompassing an erosion and sediment control plan should be developed for the site. The SWPPP is needed prior to applying for the NPDES permit. Planning Commission Planning Case No. 05-12 April 5. 2005 Page 7 Erosion Control Temporary and permanent erosion control plans and details should be developed. Temporary erosion control could consist of Type 1 mulch and temporary seed mixes. Erosion control blanket should be applied to the storm water pond and any disturbed areas between the flared end sections and the pond. Energy dissipation is needed at the flared end sections. Erosion control blanket shall be installed on all slopes greater than or equal to 3: 1. All exposed soil areas shall have temporary erosion protection or permanent cover year round, according to the following table of slopes and time frames: Tvpe of Slope Steeper than 3:1 10:1 to 3:1 Flatter than 10: 1 Time 7 days 14 days 21 days (Maximum time an area can remain open when the area is not actively being worked.) These areas include constructed stormwater management pond side slopes, and any exposed soil areas with a positive slope to a stormwater conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other natural or man made systems that discharge to a surface water. Sediment Control Street cleaning of soil tracked onto public streets shall include daily street scraping and street sweeping as needed. Inlet protection should be provided following installation. Wimco-type inlet controls are recommended. A rock construction entrance is needed from the site to West 79th Street. Chanhassen Type 1 silt fence should be installed around the south and east sides of the site. Other Agencies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley-Purgatory-Bluff Creek Watershed District, Minnesota Pollution Control Agency, Minnesota Department of Natural Resources (for dewatering» and comply with their conditions of approval. UTILITIES Municipal sanitary sewer is available to the site from the south. There is an existing sanitary sewer main along the southern property line which the applicant is proposing to connect a service line to. This connection will require the installation of a manhole on the existing sewer main. As for water, the treatment plant itself will have multiple water lines coming to/from the building. These watermains include typical distributiOlÎ mains, raw watermains to carry water directly from the wells to the treatment plant, a reclaim watermain which will carry a portion of the filter backwash water back to the plant for treatment, and spraywash mains which give the Utility Department staff the ability to clean out the backwash tanks. The actual potable water Planning Commission Planning Case No. 05-12 April 5, 2005 Page 8 service to the plant will come from the south side of the building off a relocated watermain. All of the utility improvements are required to be constructed in accord¡mce with the City of Chanhassen's latest edition of Standard Specifications and Detail Plates. Detailed construction plans, including plan and profile drawings of the proposed utilities, are required to be submitted at the time of final plat. STREETS The plans propose on extending West 79th Street approximately 250 feet east of its current terminus to serve the two proposed lots. Because this street will be extended within public or City-owned property, additional public right-of-way is not necessary. An access easement for the benefit of Lot 2 shall be recorded across Lot 1. The existing pavement width of West 79th Street is 27 feet from back-of-curb to back-of-curb. The standard pavement width for public streets in commercial/business districts in Chanhassen is 36 feet from back-of-curb to back-of- curb with a 48-foot cul-de-sac radius. In this case, staff is fine with the street width staying at 27 feet in order to stay consistent with the existing street width to the west. The cul-de-sac pavement radius is proposed at 60-feet. This radius exceeds the current standard and will provide greater area for semi-trucks to turnaround. With the expected increase in traffic on West 79th Street from deliveries to the treatment plant and the future development of Lot 2, staff is recommending that additional signage be installed near the existing Hanus Building just west of the site. The signage is needed because of the existing blind approach to motorists leaving Brown's Auto and conversely to motorists heading west from the new treatment plant. COMPLIANCE TABLE AREA (sq. ft.)

Fox Den - Planning Case No. 05-08 April 25, 2005 Page 5 15. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with a detailed haul route and traffic control plan. This condition still applies. 16. The sanitary sewer hook-up charge will only be applied to five of the six new lots. The water hookup charge will still be applicable for each of the new lots. Since the developer will be responsible for extending lateral sewer and water service to the lots, the sanitary sewer and water connection charges will be waived. The 2005 trunk hookup charge is $1,458 for sanitary sewer and $2,955 for water-main. Sanitary sewer and water-main hookup fees may be specially assessed against the parcel at the time of building permit issuance. All of these charges are based on the number of SAC units assigned by the Met Council. This condition has been modified by adding the following language "and are due at the time of building permit issuance. 17. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be aware that all public utility improvements will require a preconstruction meeting before building permit issuance.

Prior to final platting, storm sewer design data will need to be submitted for staff review. The storm sewer will have to be designed for a lO-year, 24-hour storm event. This condition has been met. Fox Den - Planning Case No. 05-08 April 25, 2005 Page 6 22. Drainage and utility easements will need to be dedicated on the final plat over the public storm drainage system including ponds and drainage swales up to the l00-year flood level. The minimum easement width shall be 20 feet wide. This condition still applies. 23. Staff is recommending that a small (1'-3') retaining wall be installed along the western right- of-way of Fox Drive south of the site. This will alleviate the steep slopes in the area and provide room for a boulevard area in back of the curb for snow storage. This condition has been met. The. plan has been changed to alleviate the need for a wall. 24. A minimum 20-foot wide easement will be required over the watermain that is outside of the right-of-way. This condition still applies. 25. The developer shall pay full park dedication fees. This condition still applies. GRADING. DRAINAGE & EROSION CONTROL The existing site has tree cover over approximately 1.5 acre of area. The plans propose to grade about 80% of the site for the new house pads, public street and cul-de-sac. The proposed grading will prepare the site for two look-out and four full basement house pads. The grading plan shows that, on average, the pad areas are being filled three to five feet for the new homes. Also, additional grading will take place south of the parcel to connect the proposed street with Fox Hollow Drive and to expand the existing storm pond. The applicant must be aware that any grading on privately-owned property will require a temporary easement. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with a detailed haul route and traffic control plan. The existing site drains from the northwestern corner to the southeastern corner of the parcel. Under developed conditions, all of the drainage from the house roofs, driveways and the cul-de-sac will be conveyed via storm sewer to the existing stormwater pond off the southeasterly corner of the site for treatment. The applicant will be required to clean the existing stormwater pond after enlargements have been completed. The pond is required to be designed to National Urban Runoff Program (NURP) standards. The applicant has submitted drainage calculations for the site and only minor changes remain. Storm sewer design data has also been submitted for staff review. Drainage and utility easements will need to be dedicated on the final plat over the public storm drainage system including ponds and drainage swales up to the l00-year flood level. The minimum easement width shall be 20 feet wide. Fox Den - Planning Case No. 05-08 April 25, 2005 Page 7 UTILITIES The plans propose on extending the sanitary sewer from an existing sanitary manhole in Fox Drive. Water will be extended from an existing watermain along the east side of the site and looped with the watermain in Fox Hollow Drive. The sanitary sewer and watermains will be considered public utility lines since they will serve more than one lot. As such, a minimum 20-foot wide easement will be required over the watermain that is outside of the right-of-way. Installation of the private service utilities for the site will require permits and inspections through the City's Building Department. According to the City's Finance Department records, the parcel was previously assessed for one sanitary sewer hookup and that assessment has been paid. As such, the sanitary sewer hook-up charge will only be applied to five of the six new lots. However, the water hookup charge will still be applicable for each of the new lots. Since the developer will be responsible for extending lateral sewer and water service to the lots, the sanitary sewer and water connection charges will be waived. The 2005 trunk hookup charge is $1,458 for sanitary sewer and $2,955 for watermain. Sanitary sewer and watermain hookup fees are due at the time of building permit issuance and may be specially assessed against the parcel. All of these charges are based on the number of SAC units assigned by the Met Council. All of the utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. The applicant must be aware that all public utility improvements will require a preconstruction meeting before building permit issuance. Permits from the appropriate regulatory agencies will be required, including the MPCA, Dept. of Health, MnDOT, and Watershed District. STREETS The plans propose to extend Fox Drive from the south side approximately 370-feet ending with a cul- de-sac. The required right-of-way for a new public street is 60-feet wide with a 60-foot radius for cul-de-sacs. The existing platted right-of-way for Fox Drive south of the site is 50-feet. For continuity with the existing Fox Drive right-of-way, the applicant is proposing a 50-foot wide street right-of-way and a 60-foot wide cul-de-sac radius. Staff is in favor of the applicant's proposal for this right-of-way variance. Surface Water Management Fees Water Quality Fees Because of the impervious surface associated with this development, the water quality fees for this proposed development are based on single-family residential development rates of $1,093/acre. Based on the proposed developed area of approximately 2.77 acres, the water quality fees associated with this project are $3,028. Fox Den - Planning Case No. 05-08 April 25, 2005 Page 8 Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an average citywide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWMP culverts, open channels, and storm water ponding areas for runoff storage. Single- family residential developments have a connection charge of $2,705 per developable acre. This results in a water quantity fee of approximately $7,493 for the proposed development. SWMP CrediJs This project proposes the expansion an existing NURP pond off-site. Because the pond is off- site, it is not eligible for credit. However, credit will be given for the replacement of one outlet structure ($2,500). At this time, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $8,021. Other Agencies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley-Purgatory-Bluff Creek Watershed District, Minnesota Pollution Control Agency (NPDES Phase II Construction Permit), Minnesota Department of Natural Resources (for dewatering), Minnesota Department of Health, Minnesota Department of Transportation) and comply with their conditions of approval. PARK DEDICATION COMPREHENSIVE PARK PLAN This site is wholly within the neighborhood park service area of North Lotus Lake Park. This park offers a wide variety of amenities including tennis courts, ball fields, a children's playground, picnic shelter, lighted hockey and open skating rinks, open space and a walking trail. Residents of Fox Den will access the park via Fox Hollow Drive. It should be noted that sidewalks are not available in Fox Hollow. No additional parkland dedication is required in this area of the City; therefore park dedication dollars will be required in lieu of land dedication for the five new lots (5 lots X $4,000 per lot = $20,000).

L " NadhLllUI..akePllrk ,ar___ North Lotus Lake Park Map COMPREHENSIVE TRAIL PLAN Three of the six lots (4, 5 and 6) have direct access to a section of the city's comprehensive trail plan. This eight-foot wide city trail is located parallel to State Highway 101 on the eastern edge of the subject property. The other three lots will access the trail via Fox Drive and Fox Hollow Drive. No additional trail construction is being recommended as a condition of this development. TREE PRESERV A TIONILANDSCAPING Canopy coverage and preservation calculations have been submitted for the Fox Den development. They are as follows: Total upland area (excluding wetlands) Baseline canopy coverage Minimum canopy coverage allowed Proposed tree preservation 2.77 ac. or 120,661 SF 56% or 67,110 SF 35% or 42,231 SF 19% or 23,185 SF Developer does not meet minimum canopy coverage allowed, therefore the difference between the baseline and proposed tree preservation is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage (42,231-23,185) Multiplier Total replacement Total number of trees to be planted 19,046 SF 1.2 22,855 SF 21 (22,855 + 1089) j Fox Den - Planning Case No. 05-08 April 25, 2005 Page 10 The total number of trees required for the development is 21. Applicant has proposed a total of 21 trees. All replacements must meet minimum size requirements. No more than one-third of the trees may be from anyone species. All 21 trees shall be planted within the proposed development. The subdivision is also required to have bufferyard plantings along Highway 101. Requirements are as follows: Location Hwy. 101- bufferyard B - 20' width 240' len th R uired 5 overstory trees 7 understory trees 12 shrubs Pro osed 4 existing ash trees 4 overstory trees 3 ever een trees The applicant does not meet the minimum requirements for bufferyard planting along Highway 101. Staff recommends that the minimum quantities be met. In reviewing the tree inventory, staff would like to note that many of the elm and boxelder trees specified on the inventory are actually green ash. This makes a difference since green ash will not succumb to Dutch elm disease as the elm will and it isn't considered an 'undesirable' tree as boxelders are. For these reasons, preserving as many of these trees as possible will help to make this development more appealing. Green ash are generally tolerant of construction and should do well through the process. Also of note on the tree inventory is the absence of some existing trees along the south property line. At least 4 green ash, 2 of which are double-stemmed, are not shown on the tree inventory. These trees are located between the existing shed and the south property line. These trees plus trees #142-144 should be protected during construction and remain on site. Staffrecommends that the silt fence be installed in front of all of these trees prior to grading in order to preserve them during development. When the building permit for Lot 1, Block 1 is submitted, these trees will be re-evaluated for preservation. The applicant is expanding the pond on city property and in doing so will be removing a number of evergreen and deciduous trees. Staff recommends that the applicant be required to plant boulevard trees along Fox Drive and Fox Hollow Drive to replace the city trees lost. To create a partial buffer for Highway 101, staff recommends that evergreens be considered for the boulevard trees along Fox Drive. COMPLIANCE WITH ORDINANCE - RSF DISTRICT Area (sq. ft.)
