Adjournment MEMO TO: HONORABLE MAYOR CITY COUNCILMEMBERS CHAIRMAN ROGER MARTIN ALL MEMBERS OF THE ADVISORY PARKS RECREATION COMMISSION FROM: CITY ADMINISTRATOR HEDGES DATE: FEBRUARY 11, 1985 SUBJECT: JOINT CITY COUNCIL /APRC MEETING A joint meeting of the City Council and Advisory Parks Recreation Commission is set for Tuesday, February 12, 1985. Attached is a copy of the agenda to be used as a guideline for discussion tomorrow evening. The Director of Parks Recreation has prepared memorandums and background information for City Council review on the following items: 1) Future development of Blackhawk Park and 2) Landscaping policy. The Director of Parks Recreation is requesting direction regarding leaf composting. The City began a pilot program last fall and if leaf composting is to continue, it will be necessary for the Department to plan accordingly for distribution and pick up of compost this spring for gardening as well as providing an area for the collection of leaf composting later this year. Also, the Director of Parks Recreation has reviewed park plans for Wedgewood, Capricorn and Schwanz Lake parks and it would be appropriate to review those park plans with the City Council at the special meeting. All three parks were included in the bond referendum and it is intended that the City proceed with development during 1985. Included on the agenda is an item entitled "Other APRC Items" which allows members of the APRC and City Council to discuss any matters pertaining to the Parks Recreation Department and /or programs. Following the joint APRC business, the City Council will continue their_ special City Council meeting for the purpose of reviewing 1) Special City census, 2) Discussion of the multifamily IDB pool and 3) Collective bargaining update. There may be additional items for review by the City Council. r 4� City Administra r TLH /jj MEMO TO: HONORABLE MAYOR CITY COUNCIL ADVISORY PARKS RECREATION COMMISSION TOM HEDGES, CITY ADMINISTRATOR FROM: KEN VRAA, DIRECTOR OF PARKS RECREATION DATE: FEBRUARY 6, 1985 RE: BLACKHAWK COMMUNITY PARK JOINT COUNCIL /COMMISSION MEETING In anticipation of the joint City Council and Advisory Parks Recreation Committee meeting, the following information is intended to act as a "briefing" and background information pertaining to the discussion on Blackhawk Community Park. In July of 1984, the issue of access and park usage was thrust upon the City with the proposed platting of the Blackhawk Oaks and Blackhawk Lake Addition. In response to the proposed platting, a review and analysis was performed by the City's Parks Consultant. The conclusion reached by the Consultant, Commission and Council was that a southerly access to the park would be essential. The current access off of Palisade Way would be used only as a secondary access or pedestrian way, dependent upon final park plan design. It was recognized during this analysis of the south access that additional park property would have to be acquired. Further, the Advisory Parks Recreation Commission wished to address the Blackhawk Park P.U.D. dedication requirements and the development of a preliminary park plan to coincide with the acquisition issues. This has been completed and was presented to the Advisory Commission in January of this year. Under discussion with the Advisory Commission has been the issue of acquisition of additional land around Blackhawk Lake, generally east of the existing park property. This acquisition would be in addition to the parkland "owed" to the City from the Blackhawk Park P.U.D.. Investigation of a possible L.A.W.C.O.N. grant application for acquisition has also been discussed. Attached to this memorandum is a reduction of the master planning for Blackhawk Community Park which reflects the current thinking for this area. Adjacent to the existing Blackhawk Park is Parcel "A" which approximates 13 to 14 acres. This is being proposed as parkland to be acquired through the Blackhawk Park P.U.D.. The additions of Parcel "B" (also owned by Mr. Dunn) and that of Parcel "C" owned by Mrs. Waldron capture the majority of the remaining unplatted lakeshore property. It is this combination of Parcels "B" and "C" which appear to be desirable for acquisition, as well as a L.A.W.C.O.N. /LCMR grant application. Another issue relative to the planning of Blackhawk Community Park is that acquisition of Parcel "D" will be necessary to accomodate the south access road. This property, as depicted, represents approximately five acres of land of Mr. Leo Murphy's. The City has no agreements with Mr. Murphy regarding parkland dedication or acquisition of this property for an access road. Discussion by Council and Commission as to the method of this acquisition and the timing of it should be reviewed. In discussion with the parks recreation grant coordinators from the State office, they seem very favorable to an acquisition grant, although acquisition is not a high priority in its funding proposals. It appears that to increase the likelihood of an award of the grant for acquisition, the City should consider one or both of the following: The first would be to combine the acquisition grant with a development proposal. The development proposal would include a roadway, parking lot, canoe access and trailway. To do this would obviously require resolution of the acquisition of the four to five acres of Leo Murphy's property for the road. The second method to enhance the acquisition relies on the overall approval of a concept plan for access to the park from the south and the road acquisition. Again, this would require the resolution of the access road alignment and ownership into Blackhawk Park. In summation, the issue to be discussed by the Advisory Commission and Council is to review the additional acquisition priorities for Blackhawk Lake /Park, the access road from the south, the acquisition of property from Leo Murphy and what might be tied to an acquisition grant or acquisition /development grant. master planning blackhawk j community park Blackhawk Lake I r� i i''i park location_ I l A� r •�.t Ate_ 1 i A A v vw�� v L /c, Lit I 1 �T T A'�p p��'�RQ3ED SOUTWAC 88 CONNECTION I L j eagan, minnesota i T tl 'I 'I I iuy 1984 1h 2W ,W l c oo I This maP e5 is la da mrrgg ���v ISI��� Mpppp Only arq ShaAC C m� M is r�e0� Mkaa� M )f�� rl1lq! f a RM MEMO TO: HONORABLE MAYOR CITY COUNCIL ADVISORY PARKS RECREATION COMMISSION TOM HEDGES, CITY ADMINISTRATOR FROM: KEN VRAA, DIRECTOR OF PARKS RECREATION DATE: FEBRUARY 11, 1985 RE: LANDSCAPE POLICY JOINT COUNCIL /COMMISSION MEETING The purpose of this memorandum is to provide some background and an update to the City Council regarding the proposed Landscape Policy since it was first introduced to the City Council in the fall of 1984. The Advisory Parks Recreation Commission, having reviewed a number of proposed plats, became increasingly concerned for the lack of attention paid to the preservation of significant existing trees within the plat and the apparent lack of attention for providing landscaping and screening. After some investigation and background work by the Special Issues Committee of the Commission, the item was presented to the City Council seeking direction. The City Council then directed the Advisory Commission to investigate what other communities were doing in the area of Landscape Policies or Ordinances and to develop draft recommendations to the City Council. The Special Issues Committee began the task by identifying specific criteria which a proposed landscape policy should address. For the past several months, the Subcommittee and Commission met to review and provide direction concerning landscape guidelines and their impact on projects. Attached is the culmination of the Advisory Commission and staff work presenting a draft proposal for the City Council's review. The Advisory Commission is looking for the direction from the City Council regarding this proposed Landscaping Policy. MEMO TO: ADVISORY PARKS RECREATION COMMISSION �4 FROM: STEPHEN SULLIVAN, LANDSCAPE ARCHITECT /PARK PLANNER DATE: JANUARY 14, 1985 SUBJECT: LANDSCAPE PROCEDURES REQUIREMENTS EVALUATION The purpose of a landscape policy or ordinance is to establish minimum requirements and standards to provide the necessary landscaping, open space, buffering and screening for quality urban development. These standards and criteria should then be utilized by the City staff, City Commissions and City Council while evaluating development proposals. The objectives of the standards are to: 1. establish maintain forestation of the City. 2. provide a required minimum amount of landscaping. 3. preserve significant existing plant material. 4. provide design guidelines for quality development. 5. provide plant material specifications. 6. achieve screening and buffering of undesirable visual elements. 7. provide ground cover requirements to control soil erosion. The existing trees and rolling hills are one of Eagan's greatest assets. These natural amenities set the City apart from other Minneapolis /St. Paul suburbs and promotes development. Accompanying development, hills are graded, building pads established, open space reduced and plant material is destroyed. A landscape ordinance /policy will establish standards insuring replacement of destroyed landscape and preservation of existing plant material. A landscape ordinance /policy will provide immediate measures to compensate and replace plant material lost with development. It also insures the forestation of the City for the future. Landscape guidelines provide an objective approach for evaluating development proposals. A landscape policy would set quantity, size and performance requirements insuring development quality and equal treatment. It also provides developers with up -front criteria for design and budgeting purposes. The following pages will provide the Commission with information regarding: Landscape issues Other communities' policies relating to these issues Staff's recommendations and rationale for the landscape policy /ordinance. 1 ISSUE: A minimum quantity of landscape materials is not currently required within developments. This condition allows the developer unlimited flexibility to plant one or 100 trees. The City currently evaluates landscape performance and quantities subjectively. This approach can provide inconsistencies, unequal treatment and offer minimal leverage. OTHER COMMUNITIES: Other communities' landscape policies /ordinances specify a minimum number of trees that a development must include. The minimum number of deciduous overstory (shade trees) and coniferous trees required per development in a commercial, office or industrial district are: 1. EDEN PRAIRIE a. One tree per 800 sq. ft. of gross building area or; b. One tree per 50 lineal ft. of total lot perimeter, whichever is greater or; c. The cost of the total number of deciduous overstory or coniferous trees, as estimated by the City, shall be greater than or equal to 3% of the project value. In no case can there be less trees than required by "a" and "b 2. PLYMOUTH a. One tree per 1,000 sq. ft. of gross building area or; b. One tree per 50 lineal ft. of total lot perimeter, whichever is greater. 3. MINNETONKA does not require a minimum number of trees. Instead, landscape quantities are based on a percentage of the installed landscape cost to project cost. The minimum number of deciduous overstory and coniferous trees for multiple residential districts: 1. PLYMOUTH a. One tree per dwelling unit. 2. BROOKLYN CENTER a. The minimum number of trees for multiple residential districts shall include 6 diameter trees, or larger, according to the following minimum schedule: One tree for the first six dwelling units (or portion thereof), one tree for each seven dwelling units (or portion thereof) in excess of six units, but not exceeding 97 units; one tree for each 10 dwellings (or portion thereof) in excess of 97 units, but not exceeding 197 units; one tree for each 13 dwelling units (or portion thereof) in excess of 197 units. 3. EDINA a. One tree per thousand square feet of gross floor area or one tree per 50 lineal feet of lot perimeter. 2 RECOMMENDATION: 1. Minimum number of deciduous overstory and coniferous trees within commercial, office and industrial districts shall be one tree per 1,000 square feet of gross building area or; one tree per 50 lineal feet of total lot perimeter, whichever is greater. (See figures 1, 2 3). 2. Minimum number of deciduous overstory and coniferous trees within multiple residential districts shall be one tree per unit. (See figure 4). 3. The developer should have the option to use less plant material, but larger plant material at a diameter inch for diameter inch or foot height for foot height equivalent. For example, if the site did not provide the area necessary for 100 trees: 50 2 1/2" diameter maples are equivalent to 25 5 diameter maples. 50 6' evergreens are equivalent to 25 12' evergreens. RATIONALE: Staff has evaluated both trees /building ratio and percent of landscape cost /project cost formulas for determining minimum number of trees. The project cost approach deals with differing land uses inequitably. For example, a 50,000 square foot warehouse and 50,000 square foot office building will differ in project cost by approximately double. Based on identical landscape cost percentages, the warehouse would be obligated to a landscape budget one -half that of the same size office building. The one tree per thousand square feet of gross building floor area or one tree per 50 lineal feet of lot perimeter (whichever is greater) has an effective track record in communities such as Plymouth, Edina and Eden Prairie. Staff has taken a sample of existing developments, applied these requirements, and found this formula to be effective. Figures 1, 2 3 are developments within the City of Eagan. Both the approved landscape plan and the landscape concept plan, as shown, conform to the ordinance /policy requirements for minimum number of trees. Meeting the minimum number of tree requirement will not insure that performance standards such as screening or buffering can be accomplished with this amount of landscaping. This requirement is only a minimum and additional plant material, berms, fencing or site planning may be necessary to insure that these performance standards are fulfilled. The one tree per unit works well in medium density, multifamily developments. The available greenspace in high density residential developments, such as apartments, occasionally cannot support the required minimum number of trees. The provision for less but larger plant material comes to play in these cases. Generally larger plant material suits the development advantageously. The plant material is not minuted by the scale of the building and the development is provided with an established visual character. 3 1 Tn i h i O •o ,:,t co (a F W U 4� co cc U Co H 13 S ARKING POND AREA A 0 0-cii I I cf) 1 FORMULA #2 FORMULA: 1 TREE PER 50 LINEAL FT.

OTHER COMMUNITIES: Other communities' landscape ordinances /policies provide incentives to the developer for preservation of existing significant plant material. 1. EDINA a. The total number of required new overstory trees may be offset by the retention of existing overstory trees on the lot provided that such trees satisfy the requirements of the ordinance as to size and species. The Planner shall determine the amount of the credit for such existing trees based upon their location and distribution on the lot. 2. EDEN PRAIRIE a. In instances where healthy plant material acceptable to City staff exists on site and can be preserved with development, the application of total project value allocated to landscaping may be adjusted allowing credits for this material. The burden shall be on the developer to demonstrate the value of the credited material. 3. PLYMOUTH a. It is the policy of the City of Plymouth to preserve the natural forest and woodland areas throughout the city, and with respect to specific site development to retain, as far as practicable, substantial tree stands which should be incorporated into the site. b. Credit for the retention of existing trees which are of acceptable species, size and location may be given to satisfy the minimum number requirements set forth in this policy and in the City Ordinances. c. Where commercial, industrial and institutional uses clearly demonstrate affirmative design efforts toward the preservation and enhancement of desirable natural site characteristics, ordinance required paved parking spaces may be reduced and installation deferred until such time as the need for the full compliment of parking. RECOMMENDATION: Credit for the preservation of significant vegetation may be given adjusting the developers obligations for required minimum number of trees. The City will determine the amount of credit based on quantity, size, type and quality of plant material preserved. RATIONALE: The preservation of our tree resource will help maintain the visual quality inherent to Eagan. Preservation of significant trees provide wildlife habitat and protect plant material which take hundreds of years to establish. The developer is given an incentive to preserve our tree resource. 8 ISSUE: Landscape areas are not required within large parking lots. The result is visual monotony, heat, wind, and decreased area for absorption of runoff. OTHER COMMUNITIES: Other communities' landscape ordinances /policies specify a minimum amount of landscaping within parking lots. 1. EDEN PRAIRIE a. Landscape areas shall be distributed within off street parking areas of 20 or more stalls providing a 5% pervious coverage. 2. MINNETONKA a. Where the total surface parking on a site exceeds 30 parking spaces, parking lot landscaping shall be provided in the amount of 10 square feet per parking space. (5%) b. Parking lot landscaping shall include all areas within a parking lot and landscape area bordered on at least three sides by parking, but shall not include buffer yards or landscaped "dead areas" at the intersection of two rows of parking. c. Parking lot landscape areas shall be reasonably distributed throughout the parking lot area so as to break up expanses of paved areas. d. Each area of parking lot landscaping shall have at least 100 sq. ft. of area and shall have no dimension less than six feet. e. Parking lot landscape area shall be provided with deciduous shade trees, ornamental or evergreen trees plus ground cover, mulch and /or shrubbery as determined appropriate. Parking lot landscape trees shall be provided at the rate of one tree for each 15 surface parking spaces provided or major fraction thereof. f. Parking lot landscaping shall be contained in planting beds bordered by a raised concrete curb or equivalent. 3. PLYMOUTH a. Parking lots shall have a minimum of one internal landscaped island- delineator in addition to any required traffic safety islands for each additional 3,000 sq. ft. of off street parking space after the first 3,000 sq. ft; such islands shall be equal in size to a single parking space and shall be bounded by concrete curbing. Trees may be installed in approved traffic safety islands used to delineate parking spaces from driving aisles and in other areas. The internal landscaped island(s) required above may be deleted if the aggregate area and trees of individual traffic islands meet or exceed the above requirements. RECOMMENDATION: Landscape areas shall be distributed within off street parking areas of 20 or more stalls providing a 5% pervious coverage. 9 RATIONALE: A five percent pervious coverage provides adequate landscape area for shade trees to visually break up the monotony associated with large parking lots. The 20 stall recommendation is simply a place to begin the 5% requirement. A 20 car lot is large enough (64' x 100 to accommodate landscape areas. The 5% coverage provides greater effectiveness the larger the parking lot. (See figure 5). 10 20 STALLS AT 5% LANDSCAPE AREA i 50 STALLS AT 5% LANDSCAPE AREA u rrw� 100 STALLS AT 5% LANDSCAPE AREA FIGURE #5 11 ISSUE: Performance standards are not established for screening /buffering of parking lots, utility areas, loading docks and outdoor storage areas from public roads and adjacent differing land uses. OTHER COMMUNITIES: Other communities' landscape policies /ordinances require that a development meet screening /buffering performance standards. 1. EDINA a. Non residential principal buildings or structures, and any building or structure accessory thereto, shall be screened from lots in the R -1 District which are used for single dwelling unit buildings and which are located within 200 feet of the non residential use. Said distance shall be the shortest distance between the non residential buildings or structures to be screened and the nearest lot line of the R -1 District lot, but shall not extend across a street; b. Principal buildings or structures, or any building or structure accessory thereto, located in the Planned Industrial District or Planned Commercial District shall be screened from lots used for any residential purpose which are located within 200 feet. Said distance shall be the shortest distance between the PID or PCD building or structure to be screened and the nearest lot line of the residential lot, but shall not extend across a street; c. Off- street parking facilities containing six or more spaces and all loading facilities shall be screened from streets located within 50 feet, and from lots which are used for any residential purpose which are located within 50 feet. Said distance shall be the shortest distance between the parking facility or loading facility and the nearest part of the street or the nearest lot line of the residential lot; d. Trash storage facilities shall be screened from all lot lines and public road rights -of -way; and e. All mechanical equipment accessory to any building, except single dwelling unit and double dwelling unit buildings, shall be screened from all lot lines and streets. 2. EDEN PRAIRIE a. All parking, loading, utility and outdoor storage areas shall be screened from all public roads and adjacent differing land uses. RECOMMENDATION: The landscape policy /ordinance include the following standards: 1. Screening of parking lots from all public roads, 2. Screening of parking lots from adjacent differing land uses, a. office, industrial, commercial parking lots next to residen- tial developments, b. multifamily residential parking lots next to single family residential developments, '2 z 3. Screening of loading, utility and outdoor storage areas from all public roads, 4. Screening of loading, utility and outdoor storage areas from adjacent differing land uses, 5. A buffer shall be placed between: a. office, commercial, industrial land uses adjacent to residen- tial land uses b. multifamily residential adjacent to single family residential c. office, commercial, industrial and multifamily residential land uses adjacent to parkland or significant nature areas (i.e. wetlands, creeks) RATIONALE: The objective is to screen or buffer undesirable visual elements and provide an attractive result. Screening of parking lots from adjacent roads will provide 'curb appeal" throughout the City. It is important to remember that a City is generally viewed from the seat of a car. Screening parking lots from adjacent residential developments maintains the residential visual quality expected within our neighborhoods. Screening of loading docks, utility areas and outdoor storage from public roads and adjacent differing land uses protects the public from these undesirable visual elements. The implementation of buffers between differing land uses aids in the transition between land uses. It also provides a transition in scale of buildings between office, commercial, industrial developments adjacent to residential and nature areas. 13 ISSUE: Plant specifications are not currently determined for developments. The developer is able to plant any type and size of plant material. The City currently evaluates plant specifications subjectively. This approach can provide inconsistencies and unequal treatment. The developer is able to plant undersized plant material which lack hardiness and variety necessary to provide a healthy and quality landscape. OTHER COMMUNITIES: Other communities' landscape policies /ordinances specify minimum size and plant specification requirements. 1. PLYMOUTH a. Required trees shall be of the following minimum planting size: 1. Deciduous trees 2.5 inches diameter as measured six inches above the ground. 2. Coniferous trees 6 feet in height. b. A minimum of fifteen (15) percent of the required minimum number of trees for mu1 tires idential developments shall be long -lived hardwood deciduous trees, 3.5 inches in diameter as measured six inches off the ground. c. Evergreen shrubs used for screening purposes, including those used in con juction with berming, shall be a minimum of 24" in height. Species d. All trees used in site developments shall be indigenous to the appropriate hardiness zone and physical characteristics of the site. e. All deciduous trees proposed to satisfy the minimum requirements of this policy shall be long -lived hardwood species. f. The compliment of trees fulfilling the requirements of this policy shall be not less than 25 percent deciduous and not less than 25 percent coniferous. 2. COON RAPIDS a. All shade trees shall have a minimum 2 1/2" caliper except where parking or drives parallel street rights -of -way in which case 3" caliper trees shall be used. b. All ornamental or understory trees shall have a minimum 1 112" caliper. c. All coniferous trees shall have a minimum planting height of 7 feet where parking or drives parallel street rights -of -way, 6 feet in all other instances. d. Coniferous shrubbery shall be the following minimum sizes: a. Spreading 3 gallon b. Medium 5 gallon c. Upright 3 1/2 to 4 feet 14 e. Deciduous shrubbery shall have a minimum planting size of 24 to 30 inches. f. The City of Coon Rapids lists an array of acceptable plant material which can be used within a development. 3. EDEN PRAIRIE a. Deciduous Overstory 2 1/2" diameter measured 6 above the ground. b. Deciduous Understory 1 3/4 diameter measured 6 above the ground. c. Coniferous 6' in height. d. The plant material shall have an overall average size exceeding the required minimum size for: Deciduous Overstory 2 3/4 diameter Coniferous 6 1/2' in height RECOMMENDATION: Establish minimum size requirements and specifications for all plant material. The requirements are as follows: 1. Minimum size requirements a. Deciduous Overstory Trees 2 112" diameter measured 6 above the ground. b. Deciduous Understory Trees 1 3/4 diameter measured 6 above the ground. c. Coniferous Trees 6' in height. d. The plant material shall have an overall average size exceeding the required minimum size for: Deciduous Overstory Trees 2 3/4 diameter Coniferous Trees 6 112' in height 2. Plant material specifications a. All trees shall be comprised of species which are classified hardy to this region by the American Nurseryman Association. b. The compliment of trees fulfilling the requirements of the policy shall be not less than 25% deciduous overstory and not less than 25% coniferous. There shall be no specie which composes more than 50% of the required number of trees. 15 RATIONALE: The minimum size requirements as recommended are typical of most communities. This size plant material provides: A positive visual consequence which has screening potential and relates to the mass /height of most buildings. An increase in survival rate. A reasonable cost to the developer. The percentage of coniferous /deciduous overstory trees recommendation provides: Evergreen plant material for screening. Disease protection in the case where one species of plant material would be infected (i.e. American Elm). Visual variety. The average plant material size recommendation insures that larger plant material is used. Typically a developer will meet minimum size requirement. The result is an environment with a consistent and monotonous visual quality. The introduction of several sizes of plant material provides: Placement of large plant material in areas where increased size is needed. A natural and established visual quality. 16 ISSUE: Existing developments are currently not obligated to maintain the landscape in a healthy and attractive condition. OTHER COMMUNITIES: Other communities' landscape policies /ordinances require that all landscape areas be maintained in accordance with the city approved landscape plan. 1. EDINA a. The owner of the lot upon which the required landscaping or screening is located shall maintain all materials in a sightly and healthy growing condition without cost to the City. 2. EDEN PRAIRIE a. Landscapes shall conform with the planting plan approved by the City at the time the building permit was issued. It is the owner's responsibility to see that this landscaping is maintained in an attractive and well -kept condition. All vacant lots, tracts, and parcels shall also be properly maintained in accord- ance with their natural or existing character. 3. MINNETONKA a. In order to provide for adequate maintenance of landscape areas, the underground sprinkling system shall be provided as a part of each development, excepting natural areas to be preserved and landscape areas not contiguous to principal landscaped areas. RECOMMENDATIONS: Landscapes shall conform to the approved landscape plan. The approved landscape shall be maintained in a healthy condition. The functional and visual qualities expected of the landscape plan at the time of approval shall be maintained throughout the existence of development. RATIONALE: Obligating the owner to maintain the landscape according to the approved landscape plan insures that the performance standards (i.e screening, buffering, minimum number of trees) are maintained within the development. 17 ISSUE: A minimum amount of pervious surface (green space) is not required within developments. This allows developments to maximize site coverage with building and parking lot resulting in additional run —off, lack of landscape area, and aesthetic monotony. R OTHER COMMUNITIES: 1. COON RAPIDS a. 15% green space lot coverage 2. MINNETONKA a. 20% green space lot coverage 3. FRIDLEY a. 15% green space lot coverage 4. EDEN PRAIRIE a. No percentage is required. Green space is provided by setback requirements for both the building and parking lot. No parking is allowed within the building front yard setback, allowing a large green space for landscaping. RECOMMENDATION: Staff seeks direction from the Commission regarding pervious surface within developments. RATIONALE: This issue relates to both landscape policy /ordinance and zoning requirements. It is necessary to provide adequate green space to place the required plant material in accordance with the landscape ordinance /policy. As well, prescribing a certain percent impervious coverage must relate to zoning requirements, i.e., building/ lot coverage, setbacks, minimum number of parking stalls. Providing too much green space is not cost efficient for the developer, while too little green space may not provide the area necessary to landscape in accordance with requirements for the minimum number of trees and screening. 18 LANDSCAPE POLICY PROCESS The processing and review of any landscaping policy should be simple and follow as closely as possible the existing plat application process. If this procedure is to be followed, the following would be suggested: 1. Plat application material picked up by developer; City Landscaping Policy and criteria provided. 2. Developer /staff review of plat application materials and preliminary landscaping plan. 3. Plat materials and detail landscaping plan submitted; staff reports prepared for Advisory Planning Commission and Advisory Parks Recreation Commission with staff report on compliance of the landscaping plan with City policy. 4. Advisory Planning Commission's meeting. Recommendations on the plat to the City Council and comments on the landscaping plan made. 5. Advisory Parks Recreation Commission's recommendation for park dedication requirements and recommendations on the landscaping plan provided. 6. City Council action on preliminary plat application; if approved landscaping plan becomes part of the development agreement. 7. Staff inspection of landscaping as development is completed and bond reductions sought by developer. 8. One year review of development to insure unhealthy or dead material has been replaced in compliance with the one growing season landscaping guarantee. This format for the review of the landscaping plan follows the existing procedures for plat review. Alternative methods of processing would be for the developer to submit a detailed landscaping plan to the staff for review (in compliance with the City's policy) at A) after the Advisory Planning Commission's review or B) after City Council preliminary plat approval. Alternative A is a response to the applicant's not desiring to prepare or pay for a detailed landscaping plan until after the public hearing by the Advisory Planning Commission. Changes suggested by the Advisory Commission regarding the plat or public comment by interested neighborhood and community groups may have a significant impact and result in changes in the landscaping plan. This being the case, Alternative I would be a way to respond to that situation. Generally there are ten days between the Advisory Planning Commission and the Advisory Parks Recreation Commission meetings which should be sufficient time for the developer to prepare a detailed landscaping plan. This plan could then be submitted to the Advisory Parks Recreation Commission for review and comment and then to the City Council for action along with the plat application. 19 Following the reasoning that there may be changes in the plat, not only at the Advisory Planning Commission's level but also at the City Council level, it might be appropriate for the developer to submit a landscaping plan only after a preliminary plat approval. However, this method would not provide opportunity for public review and comment or for review of deviations from the City policy. Public review and comment of the landscaping policy may be desirable with issues relating to the type, quality and size of plant material associated with screening or buffering between adjacent land uses. Staff prefers the alternative in which a landscape plan is received by the City as a component of the initial minimum submittal requirement for development review. PROCESS FOR EXISTING PLATTED PROPERTY Prior to the issuance of the building permit, the developer is required to submit the landscape /screening plan to City staff for review and approval. The landscape /screening plan will be checked by staff for policy compliance prior to issuance of the building permit. Included with the plan, the developer provides to the City a security bond which insures the implementation of the approved landscape plan. A contract form is signed between the City and developer which ties the security to the approved landscape /screening plan. Staff has the authority, if necessary, to have the landscape plan revised prior to approval and issuance of the building permit. -20- SUMMATION• The landscape ordinance /policy establishes objective minimum standards for quality development with landscaping. Staff's research of other communities policy /ordinance has resulted with a hybrid of recommendations tailored for a concise, easily understood and administrated policy.
