HomeMy WebLinkAboutGLENMOOR DRIVE PUD - PRELIMINARY - 8-95A - CORRESPONDENCE - STAFF'S PROJECT COMMENTSI-, GUIDE TO LANDSCAPE WATER -REQUIREMENT CATEGORIES 8/22/94 This guide is intended as an aid in fulfilling the City's water conservation landscape standard requiring that landscape plans include the total area of each landscape category, as distinguished by water requirements. Landscape water -requirement categories are listed below, with representative plants. This is obviously not a comprehensive list; it is only intended to provide some direction in identifying the appropriate category. A more extensive plant list will eventually be developed. TURFGRASS 1. High: Kentucky bluegrass and/or perennial ryegrass 2. Moderate: tall fescue 3. Low: buffalograss and/or blue grama grass ORNAMENTAL PLANTING BEDS 1. High: hosta, fern, dogwood, willow, spruce, fir, Norway or Sugar Maple 2. Moderate: ajuga, periwinkle, columbine, daylily, thyme, candytuft, sweet woodruff, iris, potentilla, viburnums, green ash, honeylocust, hackberry, Kentucky coffeetree 3. Low: gaillardia, hardy ice plant, Russian sage, purple coneflower, coreopsis, snow -in -summer, yarrow, Iamb's ear, Siberian peashrub, junipers, ponderosa pine, Russian hawthorne, western sandcherry, gambel oak, three -leaf sumac, ginnala maple 4. Very low: cacti, sedums, hens and chicks, poppy mallow, evening primrose, mountain mahogany, rabbitbrush, sagebrush, pinyon pine NON -PLANT AREA Non -irrigated, non -plant areas of the landscape, other than parking lots and drives. Includes such areas as walks, patios, and other "hardscapes". 4 LANDSCAPE STANDARDS A. Landscape Plan 1. The landscape plan shall contain a general note calling for the review and approval by the City of Fort Collins of any required irrigation system for the landscape. 2. The landscape plan shall include the total area (in square feet) for each landscape category. Landscape categories are distinguished by their water requirements and intended maintenance level. Examples of possible categories include, but are not limited to, high water turfgrass, low water turfgrass, low water planting beds, moderate water planting beds, and non -plant areas (paved areas, etc.). (See the attached list for a general guide for this item.) B. Plants and Design 1. To the extent practical, plants with similar water requirements shall be grouped together on the same irrigation zones. 2. The landscape shall be designed with efficient irrigation layout in mind. For example, the dimensions of turfgrass areas should be in multiples of the radius of throw of the specified sprinklers, and the geometry is such that overspray is minimized. 3. Steep grades shall be minimized. Where steep grades are necessary, the landscape shall be designed to minimize water runoff and to take advantage of the water that does run off. 4. Where south -facing berms of 25% slope or greater exist, the plants used should be lower water -requiring species. 5. Narrow landscaped strips (less than 8' wide) shall be minimized. Where necessary, such as between sidewalk and street, they should be planted with lower water -requiring plant species. C. Use of Mulches 1. Mulches shall be used for planting beds. The mulch can be either organic or inorganic, and shall be applied to a minimum depth of 3 inches. In order to prevent large expanses of barren mulch, there shall be a minimum plant cover of 50 percent within 5 years of planting. D. Natural Area Preservation 1. If there are portions of the site that are worthy of preservation, the alternative of leaving them undisturbed or with only slight improvements should be considered. The worthiness of such sites shall be determined by the City's Natural Resources Director. 3 HOW WILL THE STANDARDS BE ENFORCED? The landscape plan must meet the landscape standards in order for the associated development to be approved by the City. The irrigation plan must meet the irrigation standards prior to the issuance of a building permit for the associated construction. Both the landscape and irrigation systems must be installed according to the approved plans, or an acceptable bond deposited with the City, prior to the issuance of a certificate of occupancy for the associated building(s). IS THEIR ANY FLEXIBILITY IN THESE STANDARDS? One important characteristic of these standards is that they include a certain amount of flexibility. Some of the individual standards are strongly worded with "shall", whereas others use the softer phrases such as "should" or "to the extent practical". This approach allows for the establishment of mandatory standards for the landscaping techniques that are most important to water conservation and that are more easily met, while still retaining some flexibility for the techniques that need to be assessed on a case by case basis. ARE THERE OTHER WATER -CONSERVING LANDSCAPING PRAC77CES THAT THE CITY ENCOURAGES? Although the following landscape design and construction practices are not required by the City, they are strongly encouraged: • An analysis of the landscaping soil on the site by a soil testing laboratory is extremely useful. At a minimum, the test should determine the soil texture, percentage of organic matter, major nutrient levels, and pH. Any horticultural recommendations from the testing lab should be followed. The soils in the Fort Collins area are typically very low in organic content and high in clay. There is significant horticultural benefit and potential water -saving benefit to incorporating at least three cubic yards of composted manure per 1000 square feet of landscape area, to a depth of six inches or more. The use of lower water -requiring grass species for turf and ornamental areas is strongly encouraged. Tall fescue grass is an excellent water -conserving substitute in most situations where Kentucky bluegrass would otherwise be used. Buffalograss, blue grama grass, little bluestem, sideoats grams, smooth bromegrass, crested wheatgrass and western wheatgrass should be considered for low maintenance, more "natural -looking" applications. All of these grasses have their particular advantages and disadvantages. There is no single best turfgrass to use for all situations. Contact the Water Utility at 221-6681 or the CSU Department of Horticulture at 491-7019 for more information on grasses. FOR MORE 1NFORMA77ON. The City Water Utility is a good resource for information on water -conserving landscaping and irrigation practices. If you would like more information on these topics, or if you have any questions or comments about these standards, contact the City's Water Conservation Specialist at 221-6681. CITY OF FORT COLLINS WATER CONSERVATION STANDARDS FOR LANDSCAPES 9/16194 GENERAL INFORMATION WHAT IS THE PURPOSE OF THESE STANDARDS? In the spring of 1994 the Fort Collins City Council adopted water conservation standards for both landscaping and landscape irrigation systems. (The landscape irrigation standards are available as a separate document.) The purpose of these standards is to foster the conservation of water used for landscape watering. The specific intent is to promote the installation of landscapes that require less water, and irrigation systems that are able to efficiently and uniformly apply that amount of water. However, it is recognized that these measures will not necessarily preclude the person scheduling the irrigation from wasting water by applying more than is necessary. For that reason, these measures are seen as only one piece of an overall water conservation plan. WHAT WAS THE PROCESS USED IN ESTABLISHING THESE STANDARDS? These standards represent a year -long process that included considerable opportunities for input from "potentially -affected interests", relevant City staff, citizen advisory boards, and city council. More specifically, there were two general opportunities for local developers and "green industry" professionals to contribute written or verbal comments. Furthermore, two committees were convened to draft the content of the standards; one committee composed of local landscape designers and contractors for the landscaping standards, and the other committee consisted of local irrigation suppliers, designers and contractors for the irrigation standards. WHAT TFPE OF PROJECTS ARE SUBJECT TO THE STANDARDS? These standards apply to all projects within the Fort Collins city limits where the City requires the submittal of a landscape plan as part of the development review process. In general, this includes all commercial, industrial, institutional, and multi -family projects. It also includes duplexes that are being constructed as part of a planned unit development. Although it does apply to common areas of single family developments, it does not apply to the landscapes or irrigation systems of individual single family residential lots. ARE THESE STANDARDS APPLICABLE TO EXIS77NG LANDSCAPES AND IRRIGATION SYSTEMS? No. These standards will be applied to all new projects, beginning with those submitted for the October 24, 1994 Planning and Zoning Board meeting. AT WHAT POINT IN 77-IE DESIGN PROCESS WILL THE LANDSCAPE AND IRRIGA770N PLANS BE REVIEWED? Landscape plans will be reviewed as part of the development review process. Irrigation plans will be reviewed as part of the construction permit review process.

Irrigated Streetscapes: Parkways and medians with irrigated turf. Sidewalk: Tree planting enclosed by sidewalks. Typically 5 x 5 cut-outs. Non -Irrigated Streetscapes: Parkways, medians, and parking lot islands without irrigated turf. Trees may be individually irrigated by a drip or bubbler system. Non -Irrigated Detention Park areas without irrigated turf. Trees may be Pond/Park/Open Space: individually irrigated by a drip or bubbler system. Gravel or Mulch Bed: Small shrub beds and planters. The attached Species Use List has been developed by the City Forestry Division staff. Ratings are based on an evaluation of growth performance for species at each of the areas listed above. Those species rated as 3, 4 and 5 should be the dominate types used on all City property. Those rated as 3 should be used only in small quantities. Other species can be used with special approval. Lower rated species should be used occasionally on appropriate sites and only when their specific growth requirements can be provided for. The Species Use List applies to all tree plantings on City of Fort Collins property. The growth and performance of trees on other properties may be somewhat different so judgement should be used in applying this list to other areas. Also, the management objectives on private property are different and reflect small numbers of trees instead of the City's large tree population. More intensive maintenance and higher costs per tree are usually acceptable on private lands. The species listed and their ratings will be updated as new species are planted and evaluated, and more information becomes available. of the landscaping for a period of two (2) years after installation, but the amount of the same shall be reduced after installation is completed to twenty-five percent (25%) of the actual cost of such landscaping. If the required landscaping is already installed prior to issu- ance of a Certificate of Occupancy, a bond in the amount of twenty-five percent (25%) of the actual cost of the landscaping guaranteeing continued maintenance and replacement of the same for a period of two (2) years shall be required as a condition of issuance of the Certi- ficate of Occupancy. Any bond, cash deposit, or equiva- lent, deposited pursuant to this requirement shall be released upon certification by the Building Inspector that the required landscaping program has been completed and maintained in accordance with the requirements of the bond. If any landscaping required pursuant to this sec- tion is not maintained in accordance with the requirements of the final plan, such failure to maintain the landscap- ing shall be a violation of this chapter and enforceable as provided by law.

Box 200 Fort Collins, Colorado 80522 Colorado produces a wealth of native plants - colorful flowering species, grasses, shrubs and trees which are particularly well adapted to our variable climate, soils, temperatures and elevations, since they have evolved over many thousands of years. Some have been used in Colorado gardens and landscaping but many have been overlooked in our enthusiasm for exotic imported species which may be less well suited to our environment (or may escape and do too well to the detriment of natives). The Colorado Native Plant Society encourages the use of native plants In landscaping, both because of their adaptability and because we like the idea of Colorado looking like Colorado with unique regional horticulture which sets us apart from other parts of the country. Some native seeds are available from distributors in the region. It Is always better to buy seeds from as near your own area as possible. A list of regional seed suppliers follows. Other seeds would need to be gathered from the wild. (Please note: Gather ONLY seeds from plants which are plentiful. Many beautiful ones are. Seeds should NOT be gathered from rare or endangered species except for research purposes). For sources of started plants, check regional nurseries. More natives are being grown all the time and as the demand increases, so will the supply.

The zoning ordinance requires commercial uses to provide employee parking at a ratio of t,.O (2) spaces for each three (3) employees. The city will rely on an em- ployer's or developer's estimate of the number of persons to be em- ployed in a proposed project. Regardless of the accuracy of this estimate, ho'irever, an employer or developer should be aware that the ordinance requirement is an ongoing performance stanaara, and if the required ratio of parking is not provided at any point in time, it will be considered a violation of the zoning ordinance. If necessary, contact the Planning Division for reference informa- tion on average employee -per -square -foot ratios for typical busi- ness and industrial uses. -7- OF 7:77 4. pl 1.C1 ns annlrg i;IsIcn) C41 r C.; t�_1r} null 111!nC CI L yV environment deciduous ;zes everc-eerls shrucs E-'CLr1C cc,.er5 turf gra sses planting a care ct trees (2) Parking lot setbacks.

Parking setback landscaping along a street may be located in and should be incorporated with landscaping in the street right-of-way. (3) Screening. The zoning ordinance requires parking lots pith six or more spaces to be screened from adjacent residential lots and from the street. Screening from residential uses must be a "visual barrier six (6) feet in height and of sufficient opacity to block at least seventy-five percent (75%) of the light from the motor vehicle headlights.-, Screening from the street must be "of sufficient height and opacity to block at least twenty percent (20;) of the cross section view of the parking area from the street". These screening performance standards may be met in any number of different ways. A solid wall, wooden fence, earthen bern, constructed planter, or dense evergreen hedge would be neces- sary to screen seventy-five percent (75:) of a headlamp-s go i Page 2 - AdmiL,fstracive Guidelines: Sice/Landscape Plans for Commercial Uses B. Substantive Design Standards Site/Landscape plans for commercial uses submitted to the Planning and Zoning Board will be reviewed relative to the following criteria: 1. The plan should indicate a well designed landscape treatment of exterior spaces which measurably improves the overall quality of the project. This will normally require that landscaped area cons- titute from 122 to 17% of the site's total area, depending upon design objectives, and intensity or, quantity of planting materials. 2. The plan should provide landscaped separation and screening of parking lots and vehicular use areas from adjacent sidewalks and streets in the public R.O.W. This landscaped buffer should normally be at least ten (10) feet wide to allow adequate room for shade trees planted in this buffer area. Shade trees should be planted at approximately 4 foot intervals along allpublic street frontages. 3. The plan should provide landscaped "islands" in parking lots with more than a single driveway aisle. Each of these islands should include at least one full size tree and must have at least 80 sq. ft. of ground area per tree to allow for root aeration. A mix of deciduous and coniferous trees and shrubs will be encouraged. The purpose of these islands is to improve parking lots by providing visual relief with verti- cal landscape treatment and physical relief with seasonal shading. 4. The plan should provide well defined circulation for both vehicles and pedestrians. The plan should specifically address the interrelation of pedestrian and vehicular circulation and indicate proposed treatment for points of conflict. 5. The plan should preserve mature healthy trees on the site. 6. The plan should provide for permanent irrigation of all landscape materials. Normally this will require an automatic underground irrigation system. 7.

A. Necessary Technical Information. Site/Landscape Plans to be reviewed by the Planning and Zoning Board should include the following data: 1. Land Use Breakdown, including building floor area square footage and total site coverage by building, pavement, and landscaped area. 2. Existing and proposed vehicular and pedestrian circulation systems. 3. All existing trees on the site, indicating species and size and intent to -preserve or remove. 4. Extent and location of all plant materials and other landscape features. Plant material must be identified by direct labeling on the plan or by a clearly understandable legend. S. Flower and shrub bed definition must be clear and drawn to scale with dimensions. 6. Proposed plant material should be indicated at mature sizes and in appropriate relation to scale. 7. Proposed treatment of all ground surfaces must be clearly indicated: paving, turf, gravel, grading, etc. 8. Location of water outlets. If areas of planting are extensive, plans for an underground sprinkler system will be required. 9. Plant material schedule with common and botanical nacres, sizes, quantities and method of transplant. Bareroot material will be permitted, but it is discouraged on all but the smallest sizes. 10. Plants must be sized according to the following table: TYPE SIZE Standard deciduous trees i 31: i-rn to 2 in. caliper Small ornamental and flowering trees 1 1/2 in. to 1 3/4 in. caliper Evergreen trees 5 fe to 6 ft. in height Shrubs Adequate size to be consistent with design intent 4W _ �31 11.

GUIDE TO LANDSCAPE WATER -REQUIREMENT CATEGORIES 10/94 This guide is intended as an aid for meeting the City's water conservation landscape standard requiring that landscape plans include the total area of each landscape category, as distinguished by water requirements. Landscape water -requirement categories are listed below, with representative plants. This is obviously not a comprehensive list; it is only intended to provide some direction in identifying the appropriate category. TURFGRASS HIGH: Kentucky bluegrass and/or perennial ryegrass MODERATE: tall fescue LOW: buffalograss and/or blue grama grass ORNAMENTALS HIGH: Trees: aspen, birch, cottonwood, fir, non-native maple, spruce, willow Shrubs: winged euonymous, holly, hydrangea, quince, cranberry viburnum, willow, yew Perennials: cardinal flower, fern, foxglove, hosta, meadow rue, primrose, sweet woodruff MODERATE: Trees: western catalpa, crabapple, European mountain ash, hawthorne (other than Russian), golden raintree, honeylocust, linden, English/red/white oak, redbud Shrubs: spreading cotoneaster, currant, honeysuckle, lilacs, potentilla, spirea Perennials: ajuga, bleeding heart, candytuft, hardy chrysanthemum, columbine, orange coneflower, daylily, iris, lupine, peony, periwinkle, shasta daisy LOW: Trees: green ash, Kentucky coffeetree, hackberry, Russian hawthorne, Rocky Mountain juniper, ginnala/bigtooth/Rocky Mountain maple, Burr/gambel oak, ponderosa pine, Austrian pine Shrubs: junipers, Siberian peashrub, American plum, shrub rose, western sandcherry, serviceberry, three -leaf sumac Perennials: basket -of -gold, bishop's goutweed, coreopsis, gaillardia, knotweed, lamb's ear, mountain bluet, perennial flax, purple coneflower, rock -cress, snow -in -summer, yarrow VERY LOW: Trees: pinyon pine Shrubs: Apache plume, buffaloberry, cliffrose, mountain mahogany, New Mexican privet, rabbitbrush, sagebrush Perennials: cacti, gayfeather, hardy ice plant, poppy mallow, pussytoes, Rocky Mountain penstemon, Russian sage, sages, sedum, sulfur flower, wooly thyme NON -PLANT AREA Non -irrigated, non -plant areas of the landscape, other than parking lots and drives. Includes such areas as walks, patios, and other "hardscapes". 4 LANDSCAPE STANDARDS A. Landscape Plan 1. The landscape plan shall contain a general note calling for the review and approval by the City of Fort Collins of any required irrigation system for the landscape. 2. The landscape plan shall include the total area (in square feet) for each landscape category. Landscape categories are distinguished by their water requirements and intended maintenance level. Examples of possible categories include, but are not limited to, high water turfgrass, low water turfgrass, low water planting beds, moderate water planting beds, and non -plant areas (paved areas, etc.). (See the attached guide for this item.) B. Plants and Design 1. To the extent practical, plants with similar water requirements shall be grouped together on the same irrigation zones. 2. The landscape shall be designed with efficient irrigation layout in mind. For example, the dimensions of turfgrass areas should be in multiples of the radius of throw of the specified sprinklers, and the geometry is such that overspray is minimized. 3. Steep grades shall be minimized. Where steep grades are necessary, the landscape shall be designed to minimize water runoff and to take advantage of the water that does run off. 4. Where south -facing berms of 25 % slope or greater exist, the plants used should be lower water -requiring species. 5. Narrow landscaped strips (less than 8' wide) shall be minimized. Where necessary, such as between sidewalk and street, they should be planted with lower water -requiring plant species. C. Use of Mulches 1. Mulches shall be used for planting beds. The mulch can be either organic or inorganic, and shall be applied to a minimum depth of 3 inches. In order to prevent large expanses of barren mulch, there shall be a minimum plant cover of 50 percent within 5 years of planting. D. Natural Area Preservation 1. If there are portions of the site that are worthy of preservation, the alternative of leaving them undisturbed or with only slight improvements should be considered. The worthiness of such sites shall be determined by the City's Natural Resources Director. 3 HOW WILL THE STANDARDS BE ENFORCED? The landscape plan must meet the landscape standards in order for the associated development to be approved by the City. The irrigation plan must meet the irrigation standards prior to the issuance of a building permit for the associated construction. Both the landscape and irrigation systems must be installed according to the approved plans, or an acceptable bond deposited with the City, prior to the issuance of a certificate of occupancy for the associated building(s). IS THEIR ANY FLEXIBILITY IN THESE STANDARDS? One important characteristic of these standards is that they include a certain amount of flexibility. Some of the individual standards are strongly worded with "shall", whereas others use the sorter phrases such as "should" or "to the extent practical". This approach allows for the establishment of mandatory standards for the landscaping techniques that are most important to water conservation and that are more easily met, while still retaining some flexibility for the techniques that need to be assessed on a case by case basis. ARE THERE OTHER WATER -CONSERVING LANDSCAPING PRAC77CES THAT THE CITY ENCOURAGES? Although the following landscape design and construction practices are not required by the City, they are strongly encouraged: • An analysis of the landscaping soil on the site by a soil testing laboratory is extremely useful. At a minimum, the test should determine the soil texture, percentage of organic matter, major nutrient levels, and pH. Any horticultural recommendations from the testing lab should be followed. The soils in the Fort Collins area are typically very low in organic content and high in clay. There is significant horticultural benefit and potential water -saving benefit to incorporating at least three cubic yards of composted manure per 1000 square feet of landscape area, to a depth of six inches or more. The use of lower water -requiring grass species for turf and ornamental areas is strongly encouraged. Tall fescue grass is an excellent water -conserving substitute in most situations where Kentucky bluegrass would otherwise be used. Buffalograss, blue grama grass, little bluestem, sideoats grama, smooth bromegrass, crested wheatgrass and western wheatgrass should be considered for low maintenance, more "natural -looking" applications. All of these grasses have their particular advantages and disadvantages. There is no single best turfgrass to use for all situations. Contact the Water Utility at 221-6681 or the CSU Department of Horticulture at 491-7019 for more information on grasses. FOR MORE INFORMA770N: The City Water Utility is a good resource for information on water -conserving landscaping and irrigation practices. If you would like more information on these topics, or if you have any questions or comments about these standards, contact the City's Water Conservation Specialist at 221-6681. 2 CITY OF FORT COLLINS WATER CONSERVATION STANDARDS FOR LANDSCAPES 10/94 GENERAL INFORMATION WHAT IS THE PURPOSE OF THESE STANDARDS? In the spring of 1994 the Fort Collins City Council adopted water conservation standards for both landscaping and landscape irrigation systems. (The landscape irrigation standards are available as a separate document.) The purpose of these standards is to foster the conservation of water used for landscape watering. The specific intent is to promote the installation of landscapes that require less water, and irrigation systems that are able to efficiently and uniformly apply that amount of water. However, it is recognized that these measures will not necessarily preclude the person scheduling the irrigation from wasting water by applying more than is necessary. For that reason, these measures are seen as only one piece of an overall water conservation plan. WHAT WAS THE PROCESS USED IN ESTABLISHING THESE STANDARDS? These standards represent a year -long process that included considerable opportunities for input from "potentially -affected interests", relevant City staff, citizen advisory boards, and city council. More specifically, there were two general opportunities for local developers and "green industry" professionals to contribute written or verbal comments. Furthermore, two committees were convened to draft the content of the standards; one committee composed of local landscape designers and contractors for the landscaping standards, and the other committee consisted of local irrigation suppliers, designers and contractors for the irrigation standards. WHAT TYPE OF PROJECTS ARE SUBJECT TO THE STANDARDS? These standards apply to all projects within the Fort Collins city limits where the City requires the submittal of a landscape plan as part of the development review process. In general, this includes all commercial, industrial, institutional, and multi -family projects. It also includes duplexes that are being constructed as part of a planned unit development. Although it does apply to common areas of single family developments, it does not apply to the landscapes or irrigation systems of individual single family residential lots. ARE THESE STANDARDS APPLICABLE TO EXISTING LANDSCAPES AND IRRIGA77ON SYSTEMS? No. These standards will be applied to all new projects, beginning with those submitted for the October 24, 1994 Planning and Zoning Board meeting. AT WHAT POINT IN THE DESIGN PROCESS WILL THE LANDSCAPE AND IRRIGATION PLANS BE REVIEWED? Landscape plans will be reviewed as part of the development review process. Irrigation plans will be reviewed as part of the construction permit review process. 2. The landscape shall be designed with efficient irrigation layout in mind. For example, the dimensions of turfgrass areas should be in multiples of the radius of throw of the specified sprinklers, and the geometry is such that overspray is minimized. 3. Steep grades shall be minimized. Where steep grades are necessary, the landscape shall be designed to minimize water runoff and to take advantage of the water that does run off. 4. Where south -facing berms of 25% slope or greater exist, the plants used should be lower water -requiring species. El5. Narrow landscaped strips (less than 8' wide) shall be minimized. Where necessary, such as between sidewalk and street, they should be planted with lower water -requiring plant species. MULCHES 1. Mulches shall be used for planting beds. The mulch can be either organic or inorganic, and shall be applied to a minimum depth of 3 inches. In order to prevent large expanses of barren mulch, there shall be a minimum plant cover of 50 percent within 5 years of planting.

Explanations are included, as necessary. LANDSCAPE PLAN 1. The landscape plan shall contain a general note calling for the review and approval by the City of Fort Collins of any required landscape irrigation system, prior to the issuance of a building permit. 2. The landscape plan shall include the total area (in square feet) for each landscape category. Landscape categories are distinguished by their water requirements and intended maintenance level. Examples of possible categories include, but are not limited to, high water turfgrass, low water turfgrass, low water planting beds, moderate water planting beds, and non -plant areas (paved areas, etc.). PLANTS AND DESIGN FIIIIIIII 1. To the extent practical, plants with similar water requirements shall be grouped together on the same irrigation zones. (over --> ) i P.O.

Glover 1005 Country Club Road Fort Collins, CO 80524 Dear Kint, Staff has reviewed your documents for the Glenmoor Drive P.U.D., that were submitted on April 24, 1995, and would like to offer the following comments: 1. As you were notified by telephone on May 3, 1995, this combined Preliminary /Final P.U.D. submittal does not meet Final P.U.D. requirements. Staff has therefore downgraded the submittal to a Preliminary P.U.D. only. The Plat, Site/Landscape Plan, and elevations should be revised to state "Preliminary Plat", Preliminary Site/Landscape Plan" and "Preliminary Elevations." Per your request, the fees which you have paid will be held by the City and adjusted accordingly. This may result in additional review fees being owed to the City. 2. The Stormwater Utility Department comments are forthcoming. It appears that there are significant issues that need to be addressed. Please contact Basil Hamdin at 221-6589 to discuss these concerns. 3. Please show building envelopes, setbacks, and dimensions of all buildings on the Site/Landscape Plan. The alternative scheme for duplex construction comes close, but doesn't show a rear setback. 4. Please add the following note to the Site/Landscape Plan: "Landscaping of common open space areas shall be installed or secured with a letter of credit, escrow, or performance bond for 125% of the value of the landscaping prior to the issuance of a Certificate of Occupancy." 5. Fire hydrants must be located within 400' of all dwelling units, capable of providing 1,000 g.p.m. with 20 p.s.i. residual. An additional hydrant will be needed along Glenmoor Drive. 6. It does not appear that the proposed development adequately addresses wetland and stormwater management issues. Existing wetlands need to be delineated by a licensed wetland 281 North College Avenue • P.O. Box 380 Fort Collins, CO 80522-0580 • (303) 2-11-67=;0 FAX (303) 221-6378 TDD (303) 224-o002
