Park Dedication Ordinance r� PARK BOARD MINUTES April 2, 1990 Chairman Ray Johnson called the regular meeting of the Lino Lakes Park Board to order at 7: 01 p. m. on February 5 , 1990 at the Lino Lakes City Hall . Members present were: Chairperson, Ray Johnson, Board Members John Bauman, Bob Williams , Ken Johnson, Bill Nissen and George Lindy. Also present were Public Works Director, Don Volk; Park Superintendent , Marty Asleson; and Planning Secretary, Laura Elken. CONSIDERATION OF MINUTES Bill Nissen moved to approve the March park board minutes as mailed. Bob Williams seconded the motion and the motion was approved. CONSIDERATION OF PARK DEDICATION FOR A MINOR SUBDIVISION ON PROPERTY OWNED BY MARLIN HANSEN. This is a parcel of land located at the end of Otter Lake Road near West Oaks Subdivision. Mr. Hansen is proposing the creation of one lot. This item has been pulled off the Design Review Board agenda pending Corp of Engineer' s review. MOTION: John Bauman moved to recommend to the city council acceptance of a $400. 00 park dedication for the Marlin Hansen property. Bob Williams seconded the motion and the motion was approved unanimously. REVIEW OF PROPOSED PARK DEDICATION FOR ACORN/MONTAIN PROPERTY. Mort Huber from Acorn Investments approached the board. The applicant did not supply the board with a written proposal . Cliff Thatcher, Acorn Investments met with Don Volk and discussed park dedication consisting of 4 lots in the south west section of the plat , and combined with the land, a cash dedication will be collected to complete the dedication requirement . The plat will be developed in phases . Phase 1 consists of 40 lots , and phase 2 consists of 107 , with a total of 147 lots . Development/grading of the park land will be completed once development of phase 2 begins . The 5+ acre parcel to be dedicated as park land is part of the Barrott property that Rick Carlson is proposing to develop. This plat was reviewed last month by the park board. Page 1 PARK BOARD MINUTES April 2, 1990 Phase 2 of Rick Carlson' s proposed plat (PineRidge) consists of 50 acres known as the Barott property, and a portion of the Soukop property. Utilities are not available at this site yet , but once utilities are available, and development begins , the park board will require this five acre parcel to be dedicated park land. Gary Barott submitted a letter to Don Volk. The letter was handed out to the board members. In part this letter states : Because our contract with Mr. Carlson is contingent upon sewer and water being available to the development , we feel it is in our best interest not to divide or split off parcels until we can remove the contingency and proceed with the Carlson closing. I have looked at the preliminary plat and understand the limited use for the property in the south east area and approve Mr. Carlson' s plan for ponding and park land dedication. Don Volk stated that the Corp of Engineers needs to approve the grading and filling of this proposed five acre park because some of it is wetland. Don Volk discussed the park board' s wishes to obtain a 20 acre parcel to the south of the Montain property. He stated that this 20 acre parcel has a considerable amount of wetland within it , but that approximately 30% to 50% acres of the parcel would be fit for a park. Don Volk has not yet approached the owner to purchase this 20 acre parcel. Mort Huber stated that there is a lot of open space within his subdivision that is unbuildable. This open space will be recreational areas for the children. Don Volk did state that the Army Corp of Engineers has control over wetlands, and that these open spaces can not be disturbed. Ken Johnson stated that too often wetlands and low lands have been considered park land and accepted as park dedication. Ken also explained that there may be some likelyhood that buildings will be installed in this area, and there is a need for high ground to construct these buildings. Mort Huber stated that the Corp of Engineer' s have reviewed this plat . Ken Johnson asked about direct road access to the park land. There are two cul-de-sacs near the park. Mort Huber explained that trails are planned off the end of the cul-de-sacs for park access. Because of the phasing process, it will probably be three Page 2 PARK BOARD MINUTES April 2, 1990 years before development of the park is completed. Don Volk suggested that a neighborhood meeting should be organized before development of the park begins . He said that this worked well with Rice Lake Estates , neighbors appreciate it . Trails have not been addressed on the plat . There are existing trails to the east of the plat in Reshanau Lake Estates South. The applicant assured the board that in two weeks new plats will be presented to the city outlining the trails systems. It was discussed that the trail will start on the east end of the plat , connecting with Reshanau Lake ' s trail system, meander through his plat and end at the proposed park site. MOTION: Ray Johnson moved to recommend to the city council to accept the approximately 1 . 5 acre parcel in the south west end of the parcel as dedicated park land and the balance to be submitted as a $400 . 00 per lot cash dedication. The trail system will be reviewed and approved by staff. John Bauman seconded the motion and the motion was approved unanimously. George Lindy stressed that he is not comfortable with this proposal because the five acre parcel in the Barott property has not yet been claimed as park land. Don Volk stated that the Barrott property will probably be developed within the near future. He stated that when this is developed, whether it is by Rick Carlson or another developer, the park board minutes will be in the file, and staff will be able to refer to these when establishing park dedication. CONSIDERATION OF ARBOR DAY PROCLAMATION AND EARTH DAY PROCLAMATION. Marty Asleson presented the board with resolutions on both Arbor Day and Earth Day. Marty explained that earth and arbor day have come together to be celebrated on the same day. That day is April 21st . The Arbor Day program is well under way. Diane Schally is in charge of the program and John Bauman is working on supplying food for the celebration. Marty estimates that 150 people will be attending the Earth Keepers program and approximately 50 people will attend Arbor Day. Trees will be donated by Rick Walters from Northway Garden n Center. There will be many people volunteering their time in clean-up day. Page 3 PARK BOARD MINUTES April 2, 1990 The boy scouts will be helping with the food. REVIEW OF TREE REMOVAL AGREEMENT/MARTY ASLESON Marty explained that this tree removal agreement will be beneficial in protecting the resident from diseased trees on their lots. It will be up to the developer to remove all diseased trees, debark their stumps to below ground or remove stumps to a depth of six inches below ground level . The City Tree Inspector will paint a tree number on all diseased trees and notify the contractor as to which ones the contractor shall remove. Upon removal of the trees , the contractor shall paint the number painted on the removed tree on its debarked stump. This tree removal agreement outlines dumping and burning of trees, compensation to the contractor, permits and codes , responsibilities of the contractor, accident prevention, safety, cleanup, and special provisions , advising the resident , etc. Bill Nissen had two suggestions : 1 . In the tree removal agreement it states that the resident n has to be notified within 24 hours of when the developer will remove the diseased tree. Bill Nissen suggested that the adjacent property owners should also be notified. 2 . In the tree removal agreement it states that the contractor shall carry, during the life of this agreement , property damage insurance with limits in an amount of not less than $50 , 000 . 00 . . . Bill Nissen feels that this amount should be higher. The board discussed this issue. Marty stated that this is the amount required for the general contractor to be licensed in the city. Bill Nissen felt that the insurance should be $1 , 000 , 000, 000. 00 for general liability insurance. Marty also felt that if the insurance is inappropriately high a lot of good quality people would not bid for tree removal jobs . This will be sent to the city attorney for his comments . MOTION: Bill Nissen moved to send this Tree Removal Agreement to the city attorney for his review, and the board' s recommended changes will be addressed by the attorney. After the city attorney reviews this agreement, it will go to the city council for review and approval . John Bauman seconded the motion and the motion was approved Page 4 PARK BOARD MINUTES April 2, 1990 unanimously. SHADE TREE ORDINANCE/MARTY ASLESON The beginning of this ordinance reads as follows : AND ORDINANCE REGULATING THE PLANTING, MAINTENANCE, AND REMOVAL OF TREES AND SHRUBS IN THE PUBLIC STREETS, AND OTHER MUNICIPAL OWNED PROPERTY. ESTABLISHING A SHADE TREE BOARD AND ESTABLISHING THE OFFICE OF FORESTRY AS THE AGENCIES PRESCRIBING REGULATIONS RELATING TO THE PLANTING, MAINTENANCE, AND REMOVAL OF TREES AND SHRUBS IN PUBLIC PLANTING, MAINTENANCE AND REMOVAL OF TREES AND SHRUBS IN PUBLIC PLACES. PROVIDING FOR THE PRUNING AND REMOVAL OF TREES ON PRIVATE PROPERTY WHICH ENDANGER PUBLIC SAFETY. PROVIDING FOR STANDARDS AND SPECIFICATIONS OF ALL POLICY STANDARDS AND SPECIFICATIONS OF CARE PROTECTION POLICY CONCERNING SHADE TREES IN SUBDIVISION PROPERTIES PROVIDING FOR STANDARDS AND SPECIFICATIONS FOR CARE PROTECTION POLICY CONCERNING SHADE TREES ON NEW HOUSING PROJECTS. Marty stated that there is a real need for a tree ordinance like this . The city needs to work with builders and developers regarding this issue. Marty said that Anoka County is the biggest Oak Wilt county in the world. He stated that the City of Lino Lakes is n eligible to receive money from the state to help with the Oak Wilt problem. Ray Johnson suggested that the city setback requirements may cause extra damage to the trees . Marty explained that the developer has to take into consideration the positioning of the lots within the development to allow for less tree loss . As far as the setbacks Marty said that they are necessary to allow for utilities company lines , snowplowing, etc. Also, it is necessary that the developers take extreme care when clearing sites in the months of May and June in order to minimize the spread of oak wilt . MOTION: Ray Johnson moved to recommend to the city council approval of the Shade Tree Ordinance. George Lindy seconded the motion and the motion was approved unanimously. CONSIDERATION OF PARK BUILDINGS, BUILDING STANDARDS/MARTY ASLESON Marty presented the board with some examples of building sizes for various parks in Lino Lakes . This issue was discussed at the March Park Board meeting. The cost to construct a building for area parks would be approximately $75. 00 a square foot. Page 5 PARK BOARD MINUTES April 2, 1990 Marty discussed in his handout every park that he feels may require a building in the near future. George Lindy stated that at Erickson ' s Park a 700 square foot building may be too large. Marty explained that most park shelters are between 600 to 800 square feet . George Lindy stated that in looking at the available funds - can we rationalize the permanent buildings? Don Volk stated that this handout is a planning tool for the future. The needs for the future may change. REVIEW OF ICE ARENA LAYOUT - SUNRISE PARK/DON VOLK. The board received a proposed resolution supporting the Centennial Ice Arena from the Ice Arena Task Force. It reads as follows: WHEREAS , the Centennial community of Blaine, Centerville, Circle Pines , Lexington and Lino Lakes does not have access to an indoor ice arena, and WHEREAS , there are thousands of Anoka County citizens of all ages living in the Centennial area, and WHEREAS , the County has provided financial assistance to other governmental agencies in Anoka County for the purpose of providing ice arena facilities , and WHEREAS , the Centennial Ice Arena facility would serve the citizens of the entire Centennial area, including the Anoka County communities of Blaine, Centerville, Circle Pines , Lexington, and Lino Lakes, THEREFORE BE IT RESOLVED , that the County Commissioners be encouraged to designate at least $300, 000 of County funds for the purpose of assisting with the Centennial Ice Arena facility. When the park board met in March, Ben Benson spoke about the possibility of an ice arena in Lino Lakes, and the board discussed Sunrise Park as an option. Two maps were displayed to the board members. One was a picture of Sunrise Park as it is now, and the other one was Sunrise Park with the ice arena installed in the south west corner. Don Volk feels that it would be best to be located in the south east corner of the park. The reason being that the a ballfield was just installed in the south west corner, and irrigation system was installed. Access to the ice arena was discussed, and Don Volk felt that it is a possibility that Glenview Drive would be extended to Page 6 PARK BOARD MINUTES April 2, 1990 2nd Avenue, giving the ice arena better access . Anywhere you would install the ice arena a ballfield would have to be eliminated. The task force feels that 2 1/2 to 4 acres is what would be required for the ice arena. Marty and Don hope to attend future task force meetings and will keep the board informed of their progress. MOTION: Ken Johnson moved to recommend to the city council acceptance of the resolution supporting the ice arena. John Bauman seconded the motion and the motion was approved unanimously. REVIEW OF BILL HAWKINS LETTER REGARDING TRAILS. The board reviewed a letter from Bill Hawkins regarding trails. Don Volk explained what Mr. Hawkins stated in part : It would be my recommendation that the areas the city desires for trails be labeled as park on the final plat so that the city has control over these areas for park purposes which would include trailways. I don' t believe the county surveyor will accept easements for anything other than public utilities, drainage, or streets on a plat . Similarly merely labeling them as outlots would require the developer, after approval of the final plat and recording thereof, to convey the property to the city by separate warranty deed. Any time land is dedicated in a plat the city has an easement over the property for park purposes . This would give the city absolute control over the premises and would allow us to prohibit the adjoining property owners from constructing fences or planting trees on the trails. CONSIDERATION OF MINOR SUBDIVISION FOR ROSS AND ANNETTE REED. This is a parcel located in Ulmer' s Rice Lake Addition. The applicant wishes to subdivide his land creating two additional lots. MOTION: Bill Nissen moved to recommend to city council acceptance of $400. 00 per lot to fulfill park dedication requirements. George Lindy seconded the motion and the motion was approved. OPEN MIKE Page 7 PARK BOARD MINUTES April 2, 1990 John Tenneson, 126 Egret Lane was present at the meeting. He asked the board what is happening with the park at Rice Lake Estates . Don Volk explained that the city does have clear title to the land. The problem is that two tennis courts will not fit on the parcel . When park dedication was claimed in Rice Lake Estates , a neighborhood meeting was held, and the residents wanted a double tennis court . Mr. Tenneson stated that there are between 37 to 40 children under 10 years of age within the development and the development is only 50% completed. Also Mr. Tenneson complained that there are two retention areas between Sandhill and Blue Heron Drive that are a nuisance. There is high grass and weeds , and it looks terrible. He wanted to know who is responsible for the upkeep of these areas . He suggested a fence be put around these areas or that it be maintained. The board discussed options for park dedication, the possibility of installing a tot lot , possibly asking Circle Pines to donate some land and together with Rice Lake Estates install a tennis court on Circle Pines land, and other considerations for park dedication in order to install the tennis courts. After discussion Marty and Don decided to meet with Mr. Tenneson and his neighbors and talk about what the neighborhood would like to see in Rice Lake Estates . Don Volk stated that Rice Creek Watershed controls the retention ponds, and that current land owner would be responsible for maintence. Don feels this issue does need to be addressed. OLD BUSINESS Ray Johnson asked about the city' s leash laws. He requested a copy of the dog ordinance be brought to the next park board meeting. Meeting adjourned 9: 01 p.m. Page 8 C� DATE . ^7AY 30 , 1990 TO: DON FOLK FROM: MARTY ASLESON RE: PLAN REVIEW PROCESS - PARKS Recently much discussion has been generated around the topic of the Plan Review Process , particularly on newly dedicated pars: parcels . Although the results of the recent phone survey indicate that many have Parks and Recreation Departments , felt negative about neighborhood meetings, I believe that this was in response to the preliminary planning process . Somehow each Parks and Recreation Department looks at their- neighborhood statistics and receives input on their parks design, or at least they should . Please f-i nd of i.ached a copy of the Design Review Process thaU the City of Colorado Springs follows . This process was used as an exercise at a recent National Parks and Recreation , Parks Planning Conference that I attended. Although not everyone would use this exact format , nor have the staff that this Parks and Recreation Department has , the idea is sound. I have personallx,- used a modification of this process with good results . I also believe that the City of Lino Lakes would benefit from following this type of format . Please enclose this with the Park Board Agenda. PLAN REVIEW PROCESS SUMMARY FLOW CHART DIVISION REPES.

Positive grade changes from fill and sedimentation causes a decrease in soil oxygen levels. An increase in soil carbon dioxide and other toxic gases can also occur, leading to large areas of anaerobic conditions. Anaerobic soil conditions cause a decrease in the root respiration process which is essential for the uptake and transport of minerals and nutrients. 2. Anaerobic soil conditions are also produced by soil compaction, the increase in soil bulk density with a decrease in soil pore space. Compacted soil is also impervious to root penetration, and thus inhibits root development. Soil compaction is generally caused by the weight and vibrations of heavy machinery, vehicle parking, and the storage of fill and/or construction materials within the critical root zones of trees. 3. Changes in soil chemistry will adversely affect tree survival. The most frequent occurrence is the change (decrease) in soil acidity by concrete washout. Most trees native to the Anoka County are prefer slightly acid soils; concrete residues are highly basic. The leakage or spillage of toxic materials such as fuels or paints can be fatal for trees. D. Trunk and crown disturbances are generally mechanical in nature and are either caused directly by clearing and grading �. machinery, or indirectly by debris being cleared and falling into trees marked for protection. 1. Common forms of damages include stripped bark and cambium, split trunks, and broken limbs. 2 . Damage also occurs from the posting of signs such as building permits, or survey markers on trees. 3 . Indirect damage can be caused by the placement of burn holes or debris fires too close to trees. The possible range of damages include scorched trunks with some cambial dieback, the loss of foliage due to evaporative heat stress (leaf desiccation) , and completely burned trunks and crowns. SECTION VI METHODS OF TREE PROTECTION A. Planning and considerations. Tree space is the most critical factor in tree protection throughout the development process. The root system of trees can easily extend beyond the dripline of the tree canopy (Figure 3) . The root system within the dripline region is generally considered to be the critical root zone. Disturbance within this zone can directly affect a tree's chances root zones the following standards shall apply: 1. The use of tree save islands and stands is encouraged rather than the protection of individual (non- specimen) trees scattered throughout a site. This will facilitate ease in overall site organization as related to tree protection. 2 . The protective zone of specimen trees or stands of trees or otherwise designated tree save areas shall include no less than the total area beneath the tree(s) canopy as defined by the farthest canopy dripline of the tree(s) . In some instances, the City Forester may require a protective zone in excess of the area defined by the tree(s dripline. 3. Layout of the project site utility and grading plans should accommodate the required tree protective zones. Utilities must be placed along corridors between tree protective zones. 4. Construction site activities such as parking, material storage, concrete washout, hole placement, etc. , shall be arranged so as to prevent disturbances within tree protective zones. 5. No disturbance shall occur within the protective zone of specimen trees or stands of trees without prior approval by the City Forester. B. Protective Barriers 1. Active protective tree fencing shall be installed, along the outer edge of and completely surrounding the critical root zones of all specimen trees or stands of trees, or otherwise designated tree protective zones, prior to any land disturbance. 2. These fences will be a minimum four (4) feet high. Four feet orange polyethylene laminar safety fencing is acceptable. Figure 4 3. Passive forms of tree protections may be utilized to r1 delineate tree save areas which are remote from areas of land disturbance. These areas must be completely surrounded with continuous rope or flagging (heavy mill. minimum 4" wide) . All passive tree protection must be accompanied by "Keep out" or "Tree Save" signage. Figure 5 4. all tree protection zones should be designated as such with "tree save area" signs posted visibly on all sides of the fenced in area. These signs are intended to inform subcontractors of the tree protection process. Signs requesting subcontractor cooperation and compliance with tree protection standards are recommended for site entrances. 5. All tree fencing barriers must be installed prior to and maintained throughout land disturbance process and building construction, and should not be removed until landscaping is installed. C. Encroachment. Most trees can tolerate only a small percentage of critical root zone loss. If encroachment is anticipated within the critical root zones of specimen trees, stands of trees, or otherwise designated tree protective zones, the following preventive measures shall be employed: 1. Clearing activities: Roots often fuse and tangle amongst trees. The removal of trees adjacent to tree save areas can cause inadvertent damage to the protected trees. Wherever possible, it is advisable to cut minimum two (2) foot trenches (e.g. with a "ditch-witch") along the limits of land disturbances, so as to cut, rather than tear, roots. Directionally felling trees outward into disturbance areas and grinding stumps is also acceptable. .� 2 . It is very strongly suggested that all clearing in ['�• .,Tom../K� �� •►�`. _ - < J.

I'- ACTUAL FEEDER ROOT _SYSTEM _EXTENDS WELL BEYOND THE DRIP-LINE i FIGURE 3 TYPICAL CRITICAL ROOT ZONE APPENDIX A. TECHNICAL TERMS 1. Cambium - Tissue within the woody portion of trees and shrubs which gives rise to the woody water and nutrient conducting system, and the energy substrate transport system in trees. Cambium growth activity results in a tree's radial development, i.e. , increase in diameter. 2. Cambial dieback - The irreparable radial or vertical interruption of a tree's cambium, usually caused by mechanical damage, such as "skinning bark" ; or from excessive heat. 3 . Coniferous - Belonging to the group of cone-bearing evergreen trees or shrubs. 4. Critical root zone - The rooting area of a tree established to limit root disturbances. This zone is generally defined as a circle with a radius extending from a tree's trunk to a point no less than the furthest crown dripline. Disturbances within this zone will directly affect a tree's chance for survival. 5. Deciduous - Not persistent; the shedding of leaves annually. 6. Feeder roots - A complex system of small annual roots growing outward and predominantly upward from the system of "transport roots" . These roots branch four or more times to form fans or mats of thousands of fine, short, non- woody tips. Many of these small roots and their multiple tips are 0 . 2 to imm or less in diameter, and less than 1 to 2mm long. These roots constitute the major fraction of a tree's root system surface area, and are the primary sites of absorption of water and nutrients. 7 . Major woody roots - First order tree roots, originating at the "root collar" and growing horizontally in the soil to a distance of between 3 and 15 feet from the tree's trunk. These roots branch and decrease in diameter to give rise to "rope roots" . The primary function of major woody roots include anchorage, structural support, the storage of food reserves, and the transport of minerals and nutrients. 8. Root collar - The point of attachment of major woody roots to the tree trunk, usually at or near the groundline and associated with a marked swelling of the tree trunk. 9 . Root respiration - An active process occurring throughout the feeder root system of trees, and involving the consumption of oxygen and sugars with the release of energy and carbon-dioxide. Root respiration facilitates the uptake and transport of minerals and nutrients essential for tree survival. 10. Rope roots - An extensive network of woody second order roots arising from major woody roots, occurring within the surface 12 to 18 inches of local soils, and with an average size ranging from . 25 to 1 inch in diameter. The primary function of rope roots is the transport of water and nutrients, and the storage of food reserves. 11. Soil compaction - A change in soil physical properties which includes an increase in soil weight per unit volume, and a decrease in soil pore space. Soil compaction is caused by repeated vibrations, frequent traffic and weight. As related to tree roots, compacted soil can cause physical root damage, a decrease in soil oxygen levels with an increase in toxic gasses, and can be impervious to new root development. 12. -Transport roots - The system or-- framework of tree roots comprised of major woody roots and rope roots. e APPENDIX B. GENERAL CRITERIA FOR THE DETERMINATION OF SPECIMEN TREES OR STANDS OF TREES. 1. Specimen Tree: a. Any tree in fair of better condition which equal or exceeds the following diameter sizes. i) Large hardwoods, e.g. oaks, ash, black cherry, red maple etc. 30 "dbh. ii) Large softwoods, e.g. pines, cedars etc. , 36" dbh. iii) Small trees, e.g. flowering crab, maple, ironwood, etc. b. A tree in fair or better condition must meet the following minimum standards. i) A life expectancy of greater than 15 years. ii) A relatively sound and solid trunk with no extensive decay or hollow, and less than 20% radial trunk dieback. iii) No more than one major and several minor dead limbs (hardwoods only) . iv) No major insect or pathological problem. C. A lesser sized tree can be considered a specimen if it is a rare or unusual species, of exceptional quality, or of historical significance. d. A lesser size tree can be considered a specimen if it is specifically used by a builder, developer, or design professional as a focal point in a project of landscape. 2 . Specimen tree stands - A contiguous grouping of trees which has been determined to be of high value. Determination is based upon the following criteria: a. A relatively mature even aged stand. b. A stand with purity of species composition or of a rare or unusual nature. C. A stand of historical significance. d. A stand with exceptional aesthetic quality. tY FILL r � 2 :1 SLOPE 1Y DESIRED GRADE " EXISTING GRADE . . f SLOPE >`_Lwz.

A tree's ability for adequate root development, and ultimately its chances for survival, are improved with reclamation of the growing site. a. Wherever possible, the soil should be brought back to its natural grade. Unnecessary fill, erosion sedimentation, concrete washout, and construction debris should be removed. When machinery is required for site improvement, it is recommended that a "bob-cat" or similar light weight rubber tire vehicle be used so as to minimize soil compaction. APPENDIX D CHECKLIST FOR TREE PROTECTION PLAN REVIEW CONTACT THE DEPARTMENT OF FORESTRY AT 464-5562 FOR A SITE INSPECTION UPON COMPLETION OF LANDSCAPE INSTALLATION. 1. Tree Protection Plans a. Provisions for tree protection on the site shall be, as minimum, in conformance with the requirements of the City of Lino Lakes Tree Preservation Section of the Tree Ordinance. b. A tree protection plan shall be submitted either as part of the landscape plan or as a separate drawing to include the following: i) All tree protection zones. ii) Approximate location of all specimen trees or stands of trees. iii) Exact location of all specimen trees when their preservation is questionable, or might result in a ' change of the site design. iv) Indicate those specimen trees to be removed. Removal of specimen trees is subject to City Forester approval. v) Limits of clearing and land disturbance such as grading, trenching, etc. where these disturbances may affect tree protection zones. vi) Proposed location of underground utilities. vii) Methods of tree protection shall be indicated for all tree protection zones, aeration systems, staking, signage, etc. vii) The plan should indicate staging areas for parking, material storage, concrete washout, and debris burn and burial holes where these areas might affect tree protection. C. The following notes shall be indicated on both tree protection plans and grading plans in large letters: A. Contact the Forestry Department at 464-5562 to arrange a pre-construction conference with the City Forester prior to any land disturbance. B. All tree protection measures shall be installed prior to soil disturbance. oak stands be done before May 1st and after July 1st of each season. This will help to keep the inadvertent wounding of trees with the consequential spread of oak wilt. If clearing has to be done at this time. all stumps and wounded trees shall have the wood areas painted thoroughly with a tree paint. Should oak wilt get started as a result of construction during the months of May and June, then the developer/builder shall pay for all additional oak wilt control -measures. needed- to control the disease. This is- in accordance with the City of Lino Lakes disease control ordinance number 5. Where tfie City Forester has determined that irreparable damage has occurred to trees within tree protective zones, the trees must be removed and replaced. may' " ` TREE FENCING 4It r.

B. Species, Cultivars, or Varieties. 1. ' The Municipal Forester shall prepare lists of trees acceptable for planting in the public sites of the Municipality of Lino Lakes, County of Anoka, State of Minnesota. Undesirable trees shall not be recommended for general planting and their use, if any, shall be restricted to special locations where, because of certain characteristics of adaptability or landscape effect, they can be used to advantage. 2 . Only desirable, long-lived trees of good appearance, beauty, adaptability, and generally free from injurious insects or disease shall be planted in public sites. The Shade Tree Commission, in conjunction with the Municipal Forester, shall review at least once every two (2) years the species, cultivars, and varieties included on the approved list to determine if any should be removed for any reason or if certain new species, cultivars, or varieties of proven dependability and value should be added. 3 . Where street blocks have been assigned a particular species or variety on the Master Street Tree Plan, only these shall be planted subject to revision by the Municipal Forester and approval by the Shade Tree Commission. C. Planting. 1. SIZE a. Unless otherwise specified by the Municipal Forester, all medium to large deciduous tree species and their cultivars and varieties, shall conform to American Association of Nurserymen Standards and be at lease 1 1/4 to 1 1/2 inches in diameter six (6) inches above ground level, and at least eight (8) to ten (10) feet in height when planted. The crown shall be in good balance with the trunk. b. All small deciduous tree species and their cultivars or varieties, shall be at least five (5) to six (6) feet or more in height and have six (6) or more branches. 2 . Grade a. Unless otherwise allowed for specific reasons, all trees shall have comparatively straight trunks, well developed leaders and tops, and roots characteristic of the species, cultivar, or variety showing evidence of proper nursery pruning. All trees must be free of insects, diseases, mechanical injuries, and other objectionable features at the time of planting. 3 . Location and Spacing a. Based on a 40 year cycle, no tree which will attain a trunk diameter greater than twelve (12) to fifteen (15) inches shall be planted in a treelawn less than three (3) to five (5) feet in width. In treelawns less than three (3) feet in width, or where overhead lines or building setback presents a special problem, the selection of site and species shall be determined by the Municipal Forester easement rights to plant beyond the sidewalk on private property. Such easements should contain provisions granting the municipality permission to select, plant, maintain, and remove such trees under the direction of the Municipal Forester. b. Where there is a treelawn less than three (3) feet in width, legal steps should be taken to obtain easement rights to plant beyond the sidewalk on private property. Such easements should be taken to obtain provisions granting the municipality permission to select, plant, maintain, and remove such trees under the direction of the Municipal Forester. C. Trees shall be planted at least thirty (30) feet from street intersections and at least fifteen (15) feet from driveways and alleys. d. No tree shall be planted closer than ten (10) feet of a utility pole. e. Spacing of trees should be determined by the Municipal Forester according to local conditions, the species, cultivars, or varieties used, their mature height, spread, and form. Generally, all large trees shall be planted forty (40) to sixty (60) feet on center; all medium-sized trees shall be planted a minimum of thirty-five (35) feet on center; and all small trees shall be planted a minimum of twenty-five (25) feet on center. f. All planting on unpaved streets without curbs must have the special permission of the Municipal Forester who shall determine the tree's location so it will not be injured or destroyed when the street is curbed and paved. 4 . METHODS OF PLANTING AND SUPPORT a. Most small deciduous trees may be moved bare-rooted unless otherwise indicated. Roots of bare-rooted trees should be protected against drying out. b. All coniferous trees shall be moved balled and burlapped. Balled roots should be prevented from drying out at the surface of the ball and protected against injurious freezing. C. Pits dug for planting of bare-root plants shall be a minimum of twelve (12) inches larger in diameter than the diameter of the root system so as to be of sufficient size to accommodate the roots without crowding. For balled trees, the pits shall be a minimum of twelve (12) inches larger in diameter than the diameter of the ball of soil to allow proper backfill. d. Plants shall be planted no deeper than previously grown, with due allowance for settling. e. In poorly drained soil, artificial drainage shall be provided to properly drain the soil about the plant roots or tolerant species selected. f. Existing, indigenous soils shall be placed about the roots or in the back-fill around the ball. g. Postponed until the following growing season. h. Trees shall be suitable wrapped and guyed, or supported in an upright position, according to accepted arboricultural practices. The guys or supports shall be fastened so they hey will not girdle or cause serious injury to the tree or endanger public safety. 'D. Early Maintenance 1. General a. Newly planted trees require special attention to maintenance practices during one or two growing seasons following planting. All maintenance practices shall follow approved aboricultural standards. 2 . Watering a. Ample soil moisture shall be maintained following planting. A thorough watering each five (5) to ten (10) days, depending on soil type and drainage provisions, is usually adequate during the growing season. A soil auger or sampling tube is used to check the adequacy of moisture in the soil ball and/or backfill. 3 . Fertilization a. Provision of good drainage and adequate moisture of the backfill, and the soil ball of balled plants, is more important than fertilization immediately following planting. However, adequate quantities of the essential nutrient elements should be available after new growth starts. 4 . Insect and Disease Control a. Measures for the control of insects and diseases shall be taken as shown necessary by frequent and thorough inspections. Plants in a weakened condition following transplanting are often more susceptible to insects, especially borers, and some diseases than are vigorously growing trees. Where it is necessary to spray, insecticides or fungicides shall be used that are recommended for safe and effective control. 5. Pruning a. Pruning practices to be followed the first few years following planting shall consist of removing dead, broken, or injured branches, the suppression of rank, uneven growth, and usually the removal of water sprouts. Feather growth shall be removed as it reaches pencil size in diameter. b. Pruning shall be practiced subsequent to transplanting and as necessary thereafter to assure sturdy crotch development. C. Tree heads should be raised as growth characteristics and location dictates. Newly planted trees need not have lower branches removed until they are well established. Eventually, trees should have the lower branches removed to a height of at least seven (7) feet, unless in areas where lower branches do not impede traffic. E. General Maintenance 1. Pruning and Removal a. No topping or dehorning of trees shall be permitted. b. All large, established trees shall be pruned to sufficient height to allow free passage of pedestrians and vehicular traffic: ten (10) feet over sidewalks and twelve (12) feet over all streets except those that are subject to track traffic which shall have a clearance of sixteen (16 feet. C. It shall be the policy of the Municipal Arborist to cooperate with the Municipal or Utility Lighting Engineer, and vice-versa, in the placement and height of lighting standards and the development of a system of tree pruning to give effective street illumination. d. All cuts shall be made with a saw or pruner and only at the nodes or crotches. All pruning cuts shall be done according to the National Target Pruning techniques. Whereby a branch collar is left intact on the tree after cut out. No spurs or climbing irons shall be used in the trees, except when trees are to be removed. e. All dead, crossed, and rubbing branches shall be removed. f. All wounds over two (2) inches in diameter may be treated with a suitable tree would dressing. Except where a disease exhibits that would make it necessary. Such trees shall be treated with a suitable tree wound dressing. g. All tools being used on a tree suspected to be infected with a contagious disease shall be disinfected before being used on another tree. h. Whenever streets are to be blocked off to public service, police and fire departments shall be notified of the location and length of time the street will be blocked. Notification shall be given these departments upon the removal of such barriers or if such barriers are to remain longer than originally expected. i. To protect the public from danger, suitable street and sidewalk barriers, highway cones, or signs shall be used when pruning a tree. Flashing signals or flares shall be placed on all barriers or obstructions remaining in the street after dark. j . The stumps of all removed trees shall be cut to at least three (3) inches below the ground, and soil shall be replaced and the area leveled. If the area where the tree is removed is to be paved, the tree should be cut or stump removed at least six 6 inches below the ground. 2 . Spraying a. Suitable precautions shall be taken to protect and warn the public that spraying is being done. b. Spraying shall be done only for the control of specific diseases or insects, with the proper materials in the necessary strength, and applied at the proper time to obtain the desired control. All spraying practices shall conform to federal and state regulations. C. Dormant oil sprays shall not be applied to sugar maple, Japanese maple, beech, flowering dogwood, hickory, walnut, and most crab apple trees. Dormant oil sprays shall be applied to other trees only when the air temperature is 40 F or above and when it is not likely to drop below this temperature for a period of twenty-four (24) hours. 3 . Fertilization a. Fertilization of public trees shall follow the National Arborist Association or other accepted arboricultural standards. b. Formulations, rates, and methods of application of fertilizers shall be specified by the Municipal Forester. 4. Cavities a. Extensive cavity work should be preformed on trees only if they are sufficiently high in value to justify the cost. All cavity work shall conform to the National Arborist Association or other accepted arboricultural standards. 5. Cabling and Bracing a. As a general rule, cables should be placed approximately two-thirds (2/3) of the distance between the crotch and top branch ends. Rust-resistant cables, thimbles, and lags should be used. The ends of a cable should be attached to hooks or eyes of lags or bolts, and thimbles must be used in the eye splice in each end of the cable. In no instances shall cable be wrapped around a branch. b. All cabling and bracing practices with screw rods shall follow National Arborist Association or other accepted arboricultural standards. F. Amend The Municipal Forester shall have the authority to modify, or extend, with the approval of the Shade Tree Commission, the Arboricultural Specifications and Standards of Practice at any time that experience indicates improved methods or whenever circumstances make it advisable.

PURPOSE The purpose of this article is to preserve and protect significant trees or stands of trees whose loss due to land disturbances would affect the character of neighborhoods, subdivisions, public or semi-public projects. II. APPLICABILITY This article shall apply to any person that would disturb land areas and impact significant trees or stands of trees in neighborhoods, subdivisions, public and semi-public projects such as streets, utilities and parks whether disturbed by a public agency or private developer; except where the City Council may waive these requirements where there would be a greater public need for the project then to meet the requirements of this article. A public hearing shall be held before declaring such a waiver. The property owners within 350 feet of the site shall be notified at least 10 days before the hearing. The terms and provisions of Tree Preservation in the Administrator Standards section of the City Tree Ordinance apply to all activity which required the issuance of a Land Disturbance Permit. III. DEFINITIONS A. All words in these standards have their customary dictionary definition except as specifically defined herein.

Woodlot - A treed area of at least one-half acre of which at least 25% of the area includes large trees. IV PROCEDURES. (Summarized in Figure 1. ) A. Any required density reduction or increase in lot size must save signified or speciman trees. The City Council may require Rezoning and Special Use Permits. 1. The City Forester will conduct a preliminary review of all rezoning cases and special use permit applications. 2 . A field review of select cases will occur under the n following conditions: a. For community unit plans, and major development cases. b. Other cases as determined necessary by the preliminary review. 3 . Conditions to rezoning will be applied where determined necessary by the preliminary review. These conditions may either be general, or specific in nature, and will reflect the standards or provisions of the Tree Preservation section of the Shade Tree Ordinance. - 4 . The City may reduce the maximum allowed density on that part only of the development that has significant trees., where such reduction would save all or part of such significant trees. However, regardless of the requirements in this article, the minimum allowed density shall not be reduced below 67% of the allowed density in the City's land use plan for multiple dwellings. The minimum lot size shall not be increased above 15,000 square feet for single dwellings. Any required significant trees. The City Council may require the clustering of dwellings in the form of town- houses, quads, apartments or similar uses, where it is necessary to preserve significant trees. 5. Compliance to these conditions will be verified by review of a revised site plan prior to the issuance of a land disturbance permit. B. Developments shall be designed to preserve large trees and woodlots, where such preservation would not effect the public health, safety or welfare. The City may prohibit removal of all or part of a woodlot or stand of trees subject to the limitations in Section 3. In addition, nothing in this article shall prevent building on an existing lot of record, provided that such building shall be designed to save as many trees as possible. This decision shall be based on, but not . limited to the following criteria: 1. Size 2. Species, health and attractiveness of the trees, including: a. sensitivity to disease b. life span c. nuisance characteristics d. sensitivity to site grading 3 . Potential for transplanting 4. Need for thinning a woodlot 5. Effect on the functioning of a development C. Land Disturbance Permit 1. A tree protection plan shall be submitted with other permit drawings as part of the land disturbance permit process. An application fee shall be established by the City Council by resolution from time-to-time. This plan may either be a separate drawing, or part of the landscape plan, and shall include the following information. a. Definition of spatial limits. 1. Limits of land disturbance, clearing, grading and trenching. 2 . Tree protection zones. 3 . Specimen trees or stands of trees. b. Detain drawings of tree protection measures (where applicable) . 1. Protective tree fencing. 2 . Tree protection signs. 2 . These plans shall be reviewed by the City Forester for conformance with Tree Preservation Standards and administrative guidelines, and will either be approved, or returned for revisions. Reasons for denial shall be noted on the tree protection plan, or otherwise stated in writing. 3 . Issuance of the land disturbance permit is contingent upon approval of the tree protection plan. 4. City Staff may submit the plan to a consulting forester for a recommendation. Any costs shall be paid for by the developer or builder. 5. All tree protection measures shall be installed prior to land disturbance, . and inspected by the City Forester. 6. The City Forester will conduct follow-up site inspections for enforcement of the Tree Preservation Ordinance and its administrative standards. 7. If large trees are cut the density of trees shall be restored to that which existed before soil disturbance but in no case shall the applicant be required to raise the density above ten (10) trees per acre, unless part of a required planting screen. 8. If any significant tree in development or building site planting screen. 8. If any significant tree in development or building site is cut, damaged or the area within the tree's dripline has been encroached upon by grading equipment without City authorization, the City may require planting of two new trees. In addition, if the City determines that a damaged tree will probably not survive, it shall be removed by the developer. a. Any trees required to be planted shall be varied in species, shall maximize the use of species native to the area, shall not include any species under disease epidemic and shall be hardy under local conditions. Trees shall be at least 2 1/2 inches in diameter for deciduous trees and eight feet tall for coniferous trees. b.

Before any construction or grading takes place, snow fencing or erosion control fencing shall be placed around the borders of woodlots or the driplines of large trees to be preserved. Signs shall be placed along this fence line prohibiting grading beyond the fence line. SECTION V TREE AND SITE RELATED DISTURBANCES ,-, A. Tree protection zones, specimen trees or stands of trees designated to be saved must be protected from the following damages which may occur during all phases of land disturbance and construction processes. Methods of tree protection and disturbance prevention are provided in Section VI. 1. Direct physical root damage. 2 . Indirect root damage. 3 . Trunk and crown disturbances. B. Direct physical root damage most frequently occurs during site clearing and grading operations, where transport or feeder roots are cut, torn, or removed. 1. Transport and feeder roots tend to tangle and fuse among the roots of adjacent trees. The removal of trees with heavy machinery along the outer periphery of a tree save area can result in considerable damage within the tree save area. 2 . The most substantial form of root damage for all root types occurs in the form of cut roots. Roots are cut in grade reduction, or from trenching for underground utilities, sanitary sewer, or storm sewer lines. 3 . A more subtle form of root damage is the loss of feeder roots. Feeder roots normally occur within the organic layer, and the surface four inches of top soil, subsequently, these roots can be easily damaged by the track action from a single bulldozer pass. The stripping of top soil within a tree's critical root zone can totally eliminate its feeder root system. C. Indirect root damage through site modification can result from positive grade changes, temporary storage of fill material, the sedimentation of erosion materials, soil Zoning Rezoning Ordinance +--------Special Use--------Application Forms-----------------------Information Filing Case Preliminary Field o Determined by Review ------------- Review ------------ Review ----------+ preliminary Review o Requested by Planners o Ma3or Developments o C.U.P.

STATE OF tEDEPARTMENT OF NATURAL RESOURCES 500 LAFAYETTE ROAD • ST. PAU L, MI N N ESOTA • 55 t 55-4044 April 22, 1990 ^F2^ ^F3^ ^F4^ ^F5^ Dear ^F1 RE: Oak Wilt Suppression Funding Assistance As you may be aware, oak trees in Minnesota are suffering increasing losses due to Oak Wilt, a lethal disease caused by the fungus Ceratocystis fagacearum. The problem has now reached epidemic proportions and demands our urgent attention. To address this situation, the Minnesota Departments of Natural Resources and Agriculture, in cooperation with the University of Minnesota, are initiating a cooperative suppression project to be conducted on private and public lands in the state. Initially, this program will focus in Anoka County where the Oak Wilt problem is most serious, but is intended to quickly expand to all known Oak Wilt infested areas in the state. All oak species in Minnesota are susceptible to Oak Wilt, but species in the red oak group are most susceptible. Red oaks normally die in a few weeks, but white and bur oak survive infection for many years. A recent survey of the problem in the northern portion of the Metropolitan Region found 3,000 infection centers covering over 5,000 acres. Almost half of the infection centers and over two thirds of infected trees are in Anoka County. Most of these infections occurred in the past decade. MINNESOTA DEPARTMENT OF AGRICULTURE Plant Industry Division • 90 West Plato Boulevard • St.Paul,Minnesota 55107 AN EQUAL OPPORTUNITY EMPLOYER Oaks contribute greatly to our state's economy and to our environment. From an economic standpoint, oak is used by over 400 companies and contributes almost $1 billion to the state economy. Nearer to our homes, oaks are our most common and valued shade trees adding billions to property values and provide untold values to our air quality and visual environments. Without an organized and coordinated suppression effort, we can expect the disease to continue to spread freely, seriously damaging our timber resources and devastating our community environments. Successful Oak Wilt projects have been carried out in other states in the past. Control technology demonstrations have also been effective at stopping the disease in Minnesota. While we do not believe that Oak Wilt can be eradicated from Minnesota, an organized suppression effort involving federal, state, county, and community agencies in conjunction with private landowners, can reduce the damage to a small fraction of current levels. A successful suppression program will include measures aimed at (1) eliminating local spread of the fungus at known infection centers and (2) dramatically reducing the potential for long distance spread by insect vectors. The Suppression Task Force will have cost share funds available to assist counties, municipalities, and townships that develop an Oak Wilt Suppression Plan. We will work with individual counties, municipalities, and townships to develop a plan tailored to each community. We expect funding to be available to begin work this summer in a few selected communities and in the county in general in 1991. The purpose of this letter is to solicit from you a proposal that will indicate your interest in participation. The Interagency Oak Wilt Suppression Program is being developed as a multi-year, state-wide effort. It will assist in the treatment of infection centers in a prioritized order by mechanical severing of root systems and removal of spore producing trees. Initially, this project will focus in Anoka county where almost half of the state's oak wilt problem is located, but is intended to expand to include all areas in the state that have oak wilt. In addition to mechanical disruption of root grafts, the program would include managing various aspects of (1) new development, (2) building construction, (3) external building modification, and (4) oak wilt inspections. In addition to the funding assistance, technical advice would be available to communities from the Departments `"� of Natural Resources and Agriculture. In addition, the University of Minnesota will assist e through it's Extension Service and related research program. While the program is state-wide in scope, we want to structure its operations to be part of the local community and maintain leadership of the program at the community level. We hereby solicit your comments regarding this cooperative suppression project and your requests for assistance. Please send your written response by May 11, 1990, to Oak Wilt Suppression Project, Minnesota Department of Natural Resources, 1601 Minnesota Drive, Brainerd, Minnesota, 56401.
