PA87-045: On February 27, 1989, City Council adopted a General Plan Amendment to allow Low Density Single Family Residential and Open Space, Stream Corridor land use designations and policy revisions, for the Hansen Hill Ranch project. PA89-062: On November 27, 1989, City Council approved Planned Development Prezoning, Tentative Map, and Annexation proposal, 180 single family units and ±96 acres of open space, for the Hansen Hill Ranch project. PA89-115: On May 14, 1990, City Council denied General Plan Amendment, Planned Development Prezoning, and Tentative Map to redesignate open space for 10 single family custom lots. PA90-018: On March 19, 1991 the Planning Department closed this file, in response to a request from the Applicant to withdraw the Site Development Review application for the 180 lot project, in order to facilitate the redesign of the single-family units. PA89-062: On December 2, 1991, the Planning Commission approved a time extension of the Planned Development Prezoning, to May 27, 1992, coinciding with the expiration date of the approved Tentative Map 5766. PA91-099: On January 21, 1992, the Planning Commission recommended to the City Council approval of a Development Agreement for the Hansen Ranch project. -2- PAP,F a nr /OD APPLICABLE REGULATIONS: Section 8-31.18, Planned Development District Minor Modification of the Land Use and Development Plan, states if a proposed structure, facility or land use not indicated on a Land Use and Development Plan approved by the City Council does not materially change the provisions of the approved Land Use and Development Plan, the structure, facility or land use may be permitted subject to securing a Conditional Use Permit. Section 8-94.0 states that conditional uses must be analyzed to determine: 1) whether or not the use is required by the public need; 2) whether or not the use will be properly related to other land uses, transportation and service facilities in the vicinity; 3) whether or not the use will materially affect the health or safety of persons residing or working in the vicinity; and 4) whether or not the use will be contrary to the specific intent clauses or performance standards established for the district in which it is located. ENVIRONMENTAL REVIEW: A Negative Declaration has been prepared pursuant to the California Environmental Quality Act (CEQA), State CEQA Guidelines, and the City of Dublin Environmental Guidelines. The proposed project will not have a significant effect on the environment. NOTIFICATION: Public Notice of the February 18, 1992 hearing was published in the local newspaper, mailed to adjacent property owners, and posted in public buildings. BACKGROUND: A General Plan Amendment and Environmental Impact Report (PA 87-045) were approved by the City Council on February 27, 1989, allowing Low Density Single Family Residential (0.5 - 3.8 units per acre) and Open Space, Stream Corridor land use designation and General Plan policy revisions relating to Land Use, Circulation, Safety and Conservation, for the Hansen Hill Ranch project. On November 27, 1989, the City Council approved PA 89-062, for the Hansen Hill Ranch project, Prezoning the approximate 147 acres of land west of Silvergate Drive to the Planned Development District, subdividing the property into 180 single family lots, and approving the annexation of the property to the City of Dublin. The Planned Development Zoning is subject to review after May 27, 1992. The Tentative Map is valid through May 27, 1992. On May 23, 1991, LAFCO certified Annexation No. 7, bringing the approximate 147 acre Hansen Ranch property into the Dublin City limits. -3- PAGE 3 F /00 On January 21, 1992 the Planning Commission recommended approval to the City Council of a Development Agreement between the City and The Donald L. Bren Company (Hansen Ranch property owners). Said Agreement between the City and Developer is a voluntary contract in which the City agrees not to change its planning and zoning laws that apply to the development for a specified time period, and the Developer agrees to provide specific improvements and benefits which the City might otherwise have not been able to require from the Developer. On February 10, 1992, the City Council held a public hearing to introduce the Hansen Hill Ranch Development Agreement Ordinance (PA 91-099). The second reading of the Development Agreement Ordinance is scheduled for the City Council meeting of February 24, 1992. If adopted, the Ordinance would become effective 30 days later, on March 25, 1992. The Development Agreement cannot be executed until this application, PA 91-096 Hansen Ranch Conditional Use Permit/Site Development Review, is completed. It is important for the City Council to take action on the Development Agreement prior to March 1, 1992, in order to assure receipt of park in -lieu fees by April 1, 1992. ANALYSIS: Toohey Homes, Ltd., representing The Donald L. Bren Company has applied for a Conditional Use Permit to allow modifications to the approved Planned Development General Provisions and a Site Development Review for the first phase (72 lots: 68 production homes and 4 custom lots) of the 180 unit Hansen Ranch Subdivision. CONDITIONAL USE PERMIT The Conditional Use Permit request is to allow the modification of Condition No. 1.B. of City Council Resolution No. 129-89 (Attachment 3), which establishes General Provisions for PA 89-062 Hansen Hill Ranch Planned Development Prezoning. The proposed modification will permit the down -sizing of single- family units within the project. The smaller units generally provide a greater amount of usable yard space available on the lot. The plans depicting single-family units prepared by Bassenian Lagoni Architects (Exhibit A), are proposed to replace the approved plans depicting single-family units prepared by Shleppey Hesmalhalch Associates. The following table represents the differences between the two sets of single-family units: -4- PAGE µ OF / 1) Approved Unit Shleppey Hesmalhalch Plan 1 Plan 2 Plan 3 Plan 4 2,175 square feet two story 3 exterior elevations 2,910 square feet two story 4 exterior elevations side entry garage 3,270 square feet two story 4 exterior elevations 3,630 square feet two story 4 exterior elevations Proposed Bassenian Lagoni 2,097 square feet single story 3 exterior elevations 2,233 square feet two story 3 exterior elevations 2,667 square feet two story 3 exterior elevations 2,856 square feet two story 3 exterior elevations The Applicant's request to reduce the square footage of the units, and to replace the approved plans depicting single-family units prepared by Shleppey Hesmalhalch Associates with the plans depicting single-family units prepared by Bassenian Lagoni Architects (Exhibit A) could be considered a minor modification of the approved Planned Development Land Use and Development Plan and Staff recommends approval of the Conditional Use Permit, including adpotion of the findings required by Section 8-94.0 of the Zoning Ordinance. SITE DEVELOPMENT REVIEW The side entry garage units have been eliminated from the project, due to problems created by the resultant slope of the driveways (exceeding the City standard of 10%). Each of the four proposed single-family plans will offer three alternate exterior material schemes. A variety of stucco, stone, brick and hardboard siding will be combined with a total of thirteen different color schemes to provide variety within the proposed project. There are four custom lots (lots 39, 52, 57 and 58) included within the first phase of the Hansen Ranch project. Units on these lots will be required to comply with the "Custom Lot Design Guidelines" approved as part of PA 89-062 (Attachment 4), and will be subject to a separate Site Development Review approval, which may be processed one or more at a time. A Homeowners Association will be established for this project. The Association will be responsible for the maintenance of common landscape areas throughout the project. -5- PAGE 5.-- OF ID _ Staff has prepared Staff Study #1 (Attachment 5), dated February 7, 1992, which indicates slope areas with a gradient steeper than three -foot -horizontal -to -one -foot -vertical created in conjunction with this project. Areas with a resultant slope height exceeding seven feet are to be planted with 15-gallon sized trees. The trees are to be clustered, and shall observe a minimum ratio of one tree per one thousand square feet of slope area. This same policy was required in the Ahmanson, Bordeaux Estates and Kaufman & Broad Developments. The realignment and reconfiguration of the Valley Christian Center Access road, "Inspiration Drive", will be constructed as part of phase 1. Inspiration Drive provides the secondary public access to the Hansen Ranch project. Street trees will be planted along both sides of Inspiration Drive at an approximate ratio of one tree per each forty-five linear feet (±2,800 linear feet, totalling approximately 125 trees). Phased projects often cause concerns with residents living within the phased project, particularly if they are not aware of the subsequent phases of construction. Construction impacts (i.e. dust, traffic, noise, etc.) can disrupt the new homeowners. To help mitigate this problem, Staff is requiring the Applicants to obtain a written acknowledgment, secured from the individual property owner prior to sale of the unit, acknowledging the continuance of construction activity within the unoccupied phases of the project. The application has been reviewed by the applicable City departments and agencies, including the City Attorney, and their comments have been incorporated into the Conditions of Approval. Staff recommends approval of the Negative Declaration (Exhibit B) and the Applicant's request for Conditional Use Permit and Site Development Review, subject to the conditions listed in the draft resolutions (Exhibit C & D), respectively, including adpotion of the findings required by Section 8-95.5 of the Zoning Ordinance. RECOMMENDATIONS: FORMAT: 1) Open public hearing and hear Staff presentation. 2) Take testimony from Applicant and the public. 3) Question Staff, Applicant and the public. 4) Close public hearing and deliberate. 5) Adopt Draft Resolutions (Exhibits B, C, & D) relating to PA 91-096, or give Staff and Applicant direction and continue the matter. ACTION: Staff recommends the Planning Commission adopt the Draft Resolutions approving the Negative Declaration (Exhibit B), Conditional Use Permit (Exhibit C), and Site Development Review (Exhibit D) relating to PA 91-096. -6- PAGE C° OF ATTACHMENTS: Exhibit A: Project Plans Exhibit B Draft Resolution Approving Negative Declaration Exhibit C: Draft Resolution Approving Conditional Use Permit Exhibit D: Draft Resolution Approving Site Development Review Background Attachments: Attachment 1: Location/Zoning Map Attachment 2: Applicant's Written Statement Attachment 3: City Council Resolution No. 129-89, for PA 89-062 Hansen Hill Ranch Planned Development Prezoning Attachment 4: Custom Lot Design Guidelines Attachment 5: Staff Study #1, dated February 7, 1992 -7-- PAGE 7_ OF i 0 ,s7t 1, 1 \ t \-1 a SSE — — M/PLIN 5 14 E E T \ \ \ \ \ • • SITE PLAN — SUBDIVISION 5766 — PHASE 1 IIANSEN IIILL FIANCH ALAHEDA COUNTY CALIF0aNIA I / --!••••• 47,7.

All specifications must be met and exceptions must be approved in writing by the project manager. Specifications are part of the maintenance contract and the contractor and the foreman in charge are responsible for familiarizing themselves completely with the specifications. Work Included The landscape maintenance contractor is required to provide qualified supervisory personnel, labor, materials including fertilizer, pesticides, and fungicides, and appropriate equipment necessary to maintain all landscaped grounds to these maintenance specifications and to the satisfaction of Hansen Ranch. The use of subcontractors to carry out these specifications shall be approved in advance by the project manager. Supervision The landscape maintenance contractor and his foreman assigned to the project shall be experienced in all areas of commercial landscape maintenance and shall have a four year degree in horticulture or equivalent horticultural experience. The project foreman is responsible for being familiar with all aspects of these landscape specifications and shall be available to hold regularly scheduled meetings with the Owner's representative to inspect the ground areas. These inspections will be scheduled quarterly. The contractor is responsible for keeping the Owner's representative informed of all matters regarding this maintenance program. Quarterly Reporting Once each quarter the maintenance contractor will submit Hansen Ranch with a report detailing all maintenance operations for the previous quarter. Attached at the end of these specifications are the quarterly reporting forms required by Hansen Ranch. These reports shall include fertilizer applications, pesticide or herbicide applications, pruning, aeration, soil sampling, and summary of additional work performed. CAGE g. OF ID"' Hansen Ranch Landsca} Management Specifications Page 5 Consultants/Specialists Hansen Ranch may hire consultants or specialists as they deem necessary to recommend changes or improvements in the landscape maintenance program. The contractor will implement recommended changes by the consultant or specialist at the direction of the Owner. If recommended work is beyond the scope of these specifications then contractor shall perform work on a time and materials basis. Irrigation Management Contractor is responsible for sustaining healthy plant and turf growth while minimizing water use during irrigation. Frequency and duration of irrigation cycles should be reviewed on a regular basis in relation to seasonal and climatic conditions and should always use the versatility of the automatic time clock. Special consideration shall be given to the soils endemic to the area in relationship to water management techniques. Irrigation shall be done during the late night or early morning hours using multiple cycles, if necessary, to minimize runoff. All precautions should be taken to avoid irrigation water overspray onto sidewalks, parking areas, or gutters. If overspray is a problem, the contractor should recommend a way to eliminate the problem. Soil moisture detection apparatus shall be checked before irrigation. Foreman shall be familiar with water management procedures utilizing evapo-transpiration information and soil infiltration rates. Irrigation cycles shall be adjusted accordingly. A minimum 2" layer of organic mulch shall be used in non -turf areas to reduce evaporation from soil surface. Because of limitation of the irrigation design, special adjustments will be necessary to avoid over -watering of north and east exposures and some areas may require supplemental hand watering. Irrigation System - Repair and Maintenance Damage to the irrigation system caused by contractor's operation will be repaired at contractor's expense. Additional repairs caused by vandalism or otherwise beyond the contractors control will be repaired on a time and materials basis. All irrigation equipment replaced will be of original brand and if not available, will be of equal performance and cost. Weekly visual inspections shall be conducted to check for problems. Quarterly irrigation system analysis shall also be performed to assess all systems for proper operation. This analysis shall include clock adjustment, adjustment of irrigation heads for proper coverage, flushing of clogged heads, and written recommendations for irrigation system improvements, if any. Hansen Ranch Landscat Management Specifications Page 6 Replacement of Plant Material Time clocks for irrigation system shall be adjusted as required to eliminate overwatering of streesed plants. The maintenance contractor is responsible for weekly visual inspection and replacment of plant material which dies or is severely damaged by pests, disease, improper care, or negligent actions by his personnel, with plants of comparable size. It shall be the contractor's responsibility to investigate and document all previous damage prior to starting the contract. Replacement of plant material for other reasons will be done on a time and materials basis. Additional irrigation to establish replacement plants shall be applied by hand watering and shall be the contractor's responsibility at no additional charge. Hours Power equipment is to be operated between the hours of 8 a.m. and 6 p.m. on weekdays only. Other Maintenance The landscape maintenance contractor additionally is responsible for pick up of waste paper, debris, and leaves in all shrub, groundcover, and turf areas on a regular and on -going basis throughout all irrigated landscape areas. This will be completed before mowing takes place. Catch basins, fire access trails, and swales shall be maintained free of all debris and kept functional. Debris shall be removed from site at contractor's expense. Disease and Pest Control Turf - Vigorous and well maintained turf has pest, weed, or disease problems less often than poorly maintained turf. If problems occur, every effort should be made at control using proper cultural techniques in mowing, fertilizing and irrigation management. If control cannot be achieved in this manner, then and only then, may pesticides, fungicides or herbicides be considered. An accurate identification of the insect, weed, or disease shall be made by a farm advisor, entomologist, turf specialist, or pest control advisor. Based on this identification a pest control advisor or pest control operator shall specify which chemicals to use along with rates and application procedures. Additionally, alternatives and mitigation measures that would substantially lessen the environmental impact should be considered. All pesticides, fungicides, and herbicides shall be applied under the direct supervision of a licensed pest control operator after first obtaining permission from the project manager. All necessary paperwork, permits, reports, or government approvals shall be the sole responsibility of the contractor. Groundcovers, Shrubs and Trees - Minor infestations of common insect pests are acceptable and routine spraying is to be avoided. If major infestations do occur, the contractor shall be responsible for identifying the problem and treating it appropriately. Tree and shrub diseases are more serious in nature and should be PA Hansen Ranch Landscal Management Specifications Page 7 controlled immediately upon identification. Casual inspection of lower branches of trees is not satisfactory. A regularly scheduled, detailed inspection is necessary to thoroughly identify and diagnose plant problems and to prevent serious damage. Specific comments regarding individual plant species are included in Appendix "B". Contractor shall be responsible for damage or effects arising out of any and all pesticides of fungicide use. Open Space Areas - Only pest or disease infestation which threaten the survival of open space plant species shall be deemed appropriate for treatment. This treatment shall be completed under the supervision of a qualified environmental consultant and with the written consent of Hansen Ranch. All disease and pest control in open space areas shall be done by separate contract. Weed Control All tree basins, planter beds and road areas shall be kept free of weeds and grasses at all times. Weeds should be pulled and not chopped. Pre -emergent herbicides are recommended in all shrub and groundcover areas to inhibit future weed growth and shall be applied according to manufacturer's recommendations and all applicable laws. Hansen Ranch reserves the right to request and approve a detailed weed control program showing weed identification and proposed herbicides. Contractor shall be responsible for damage or effects arising out of any and all herbicide use. 4PAGE / O! Irrigated Landscape Areas PAGE 2- 0 Hansen Ranch Landsca Management Specifications Page 8 1.0 Irrigated Landscaped Areas Lawn Care Soil Samples Soil samples shall be taken from representative areas prior to the first spring fertilization. Proper soil sampling procedures as described in Appendix D shall be used. Soil samples will be sent to an approved laboratory for fertility analysis, and recommendations by that facility are to be followed by the maintenance contractor after review with the Owner's representative. The maintenance contractor is responsible for cost of soil analysis and implementation of all recommended changes. A copy of the soils report shall be submitted with the quarterly report. Fertilization Only nitrogen need be applied to turf areas unless results of soil fertility test indicate a specific problem or nutrient deficiency. If a deficiency is noted, recommendations by the soil testing facility shall be followed. Generally up to six pounds of actual nitrogen are applied per one thousand square feet of turf area per year. It is the contractors responsibility to determine analysis of fertilizer used and to calculate the amount of actual nitrogen necessary to keep turf areas lush and healthy through the entire year. Fertilizer should be applied to turf as evenly as possible and no more than one pound of actual nitrogen per one thousand square feet should be applied during any month. Fertilization is to be reduced in the summer dormancy period for cool -season grasses. In October an application of a complete slow -release fertilizer (nontemperature reactive IBDU or urea -based formulation) is required. All fertilizer is to be supplied by maintenance contractor as part of his contract. Mowing Equipment Mower blades should be sharp and tearing of grass by dull mower blades is not acceptable. All mowers shall be adjusted to the same height and scalping of high spots, mounds, or knolls will not be permitted. All mowing equipment shall be cleaned before entering premise of the project to prevent importation of disease from other mowing sites. The maintenance contractor is responsible for any damage that may occur from mowing on soils that are too wet. Heavy equipment should avoid low wet areas. If necessary wet areas shall be mowed with a hand mower. Height and Freauencv of Mowing Lawns shall be mowed a minimum of every seven days during the months of April through October and to a minimum height of two inches. During this period lawns should never be mowed below two inches and height shall not exceed 3". During the months of November through March lawns shall be mowed to a minimum height of PAGE4 O 4Oa Hansen Ranch Landscaj Management Specifications Page 9 one and a half inches and as often as necessary to maintain a neat, groomed appearance. Grass Clippings Grass clippings are a valuable source of nutrients and ideally should remain in the turf. Clippings, with the approval of the Owner, shall not be removed unless unsightly or lying in swaths that might damage lawn. Edging All lawn edges along walls, fences, foundations, sidewalks, driveways, planter beds, tree trunks, utility boxes or other objects located within a turf area will be trimmed to maintain a well groomed appearance. Trimming along concrete or asphalt areas must be done by power edging equipment on a weekly basis. Cut -Edge boundaries between lawn and groundcover areas may be edged chemically, provided the chemical used is a contact herbicide and not a systemic type. Maintained edges shall be straight, uniform and conform to the original boundary design. Dead grass and/or groundcover shall be removed immediately. Objects located within lawn areas, may be edged with an herbicide provided the dead grass is removed. Contractor shall be responsible for complete replacement of any tree or shrub which is partially or entirely girdled by edging equipment. Aeration Use of a turf core extracting device is required once a year in the first two weeks of April and should be scheduled immediately prior to fertilizer applications. Heavily compacted areas which show obvious signs of poor water penetration will be aerated additionally as necessary on a time and materials basis. Re -seeding and Special Procedures Bare spots in lawns shall be re -seeded as necessary to maintain complete coverage. De -thatching or any other special procedures required for a healthy lawn shall be performed by the contractor as needed and with the approval of the Owner. Cost for de -thatching and special procedures will be at Owner's expense. Damage Mowing equipment should never be allowed to strike trees, shrubs, or irrigation heads located in turf areas. Any partial girdling of tree trunks or damage to irrigation system caused by the operator will be repaired or replaced at the contractor's expense. Size of plant material will be equivalent to that being replaced. It will be the contractors responsibility to investigate and document all previous damage prior to starting the contract, otherwise damage will be assumed to be the contractor's. PAG Hansen Ranch Landscat Management Specifications Page 10 SHRUB CARE General An area extending to the drip line of each shrub should remain clear of any vegetation to reduce competition and encourage healthy growth. It is essential that the maintenance contractor understand the habits and cultural requirements of each shrub species at the project so he can effectively manage irrigation, pruning, and fertilization procedures. Fertilization Recently established shrubs should be fertilized in early March and late May with ammonium sulphate (20-0-0) at the rate of 5 lbs. per 1000 sq. ft. Fertilizers are to be applied uniformly to the area within the drip line of the shrub, and followed by a thorough irrigation. As shrubs reach their optimum size, fertilizer application can be reduced to once in March and eventually shrubs may need no fertilization unless showing signs of deficiency. If deficiency signs occur, then soil fertility tests should be done and recommendations followed. Contractor shall be responsible for damage arising out of any fertilizer use. Pruning The primary goal of pruning shall be to maintain the natural shape and appearance of shrubs within given space limitations. The natural tapered shape of most plants allows sunlight to reach lower foliage and should always be retained. Power pruning equipment may only be used for designated hedges, and shrubs shall not be sheared into boxes, balls, or other formal shapes unless specifically noted. All pruning cuts shall be made to lateral branches, buds, or the main trunk and shall always be flush. Stubs shall not be allowed to remain and all cuts should be clean with no tearing of the bark. For efficient control of growth, major pruning shall occur in the dormant period, while minor pruning and shaping is encouraged throughout the year. Pruning shall only be performed by trained, qualified personnel. GROUNDCOVER CARE General Groundcovers shall be maintained in a healthy condition and shall be edged and trimmed in a manner compatible with the design intent. They shall be pruned as necessary to encourage fullness and complete coverage. Some species may need annual mowing, refer to Appendix "B" for requirements. Cleared circles, 18" in diameter, shall be maintained at base of trees. Shrubs shall be cleared to drip line. No chemical clearing is permitted in groundcover areas. PAGE Hansen Ranch Landscar Management Specifications Page 11 Two to four applications of ammonium sulphate (20-20-20) applied at the rate of 5 lbs. per 1000 sq. ft. should be applied during the first year of a new planting. Application rate can be reduced in subsequent years as long as vigorous growth and a healthy condition is maintained. Once full coverage is achieved at least one application shall be applied in March. TREE CARE Pruning Tree pruning shall be done with the objective of retaining the natural form of the tree while promoting structural strength and safety. Contractor is responsible for pruning of trees up to a 8'-6" height in areas above pedestrian walks and a 15' height above vehicular use areas. Dead or dying branches or any that interfere with vehicle or pedestrian traffic along existing drives or walkways shall be removed. Pruning shall be performed by a trained, qualified person with experience in accepted procedures. Pruning shall be in accordance with the principles and practices recommended in the U. C. Extension Service Bulletin "Pruning Landscape Trees" No. AXT-288. All pruned material shall be removed from site at contractor's expense. Pruning or removal of trees over a 15' height shall be contracted out separately to a qualified tree surgeon and is not the responsibility of the maintenance contractor. Fertilization Trees in shrub areas shall receive the same fertilization application as prescribed in the shrub section. Trees in lawn should receive adequate nutrients from lawn fertilization program and should not require additional fertilization unless deficiency symptoms develop. CAGE `'1 Fi Hansen Ranch Landscai 'vlanagement Specifications Page 12 Staking All existing stakes and ties shall be maintained and replaced with equal material for one year, or until tree is able to stand free and withstand strong winds. Staking shall encourage maximum movement of the trunk to develop strength and taper Stakes and ties are to be checked and adjusted on a quarterly basis, or more often if site condition necessitate. Remove stakes when tree is able to stand alone. Trees in Turf Trees in lawn areas shall have a 24" diameter area cleared around the trunk. Trees damaged from mowing equipment or mechanical trimmers shall be replaced at Contractor's expense. Native Oaks Native oaks present in the riparian corridor at the main project entry shall be inspected on an annual basis by a certified arborist for signs of pest, disease, or structural problems. Any recommendations provided by the certified arborist shall be implemented following approval by the project manager, and under a separate contract. ROTATING ANNUAL CARE General Rotation of annuals applies to all annual planting beds. Location of rotating annuals on Map A. These color areas have high visibility and shall be maintained on a continual basis with species indicated in Appendix "A". Contractor is responsible for the removal and disposal of old flowering plants and their replacement. Rotation period given in Appendix "A" are a guideline only. Contractor shall maintain a continuous, uniform color display in these areas. This includes pinching off dead flowers weekly and replacing plants before they show signs of stress. New varieties are to be preapproved by Owner prior to installation. Fertilization A steady supply of nutrients is required for quick establishment of bedding plants. A complete slow -release fertilizer (Osmacote 14-14-14 or equivalent) is recommended in warmer months when soil is prepared for planting. Follow manufacturer rate recommendations for a three to four month application duration. Alternative is to apply granular form 15-15-15 monthly at a rate of six lbs. per 1000 sq. ft. Actual rates and frequency of applications will be dependent on the growth response of the plants. Contractor is responsible for maintaining healthy, vigorous growth. PAGE 7 O! 0 Hansen Ranch Landscaj Management Specifications Page 13 Weed Control Weeds shall be controlled as specified in the general section of this report. Special care should be given to the selection of a pre -emergent herbicide for annual beds. Annuals are more susceptible to damage from herbicides than perennial plants. Mulch A 2" layer of mulch shall be applied after annuals are planted. Mulch shall be spread between the plants, but shall not cover the stems. Mulch shall be raked from the bed and re -applied when replanting. Mulch shall be fir or redwood bark sized 1/2" to 1" diameter, and free of sticks, stones, clay or other foreign material, or approved equal.

Correctly performed soil sampling and analysis provide important information for the management of landscape plantings. A soil sample should represent only one soil or plant condition. The sample should be a mixture of 10 or more sub -samples taken from the rooting depths of existing or proposed plantings. Typical rooting depths are: Turf and herbaceous groundcovers: 0 to 6" Shrubs: 0 to 18" Trees: 0 to 12" and 13" to 36" (sample from each depth) Landscape conditions requiring different samples would be: Different soil textures or colors. Different drainage patterns. Import fills. Areas receiving different fertilizer or amendment treatments. Samples should not contain any plant or organic material from soil surface. The best collecting tool is a sampling tube which removed a core of soil from the surface to the lower rooting depths. If a shovel is used then a hole should be dug to the correct depth and a vertical 1" slice taken from the side of the hole. The sub -samples should be randomly collected from each representative area. They should be mixed thoroughly and placed in a water proof bag or container (gallon zip -lock freezer bags work well). Labels with all pertinent information should be placed on the outside of the container. Collect at least two cups of soil for each sample.

Goal: The goal of this guideline is to establish a design criteria which provides a framework of compatibility between the production units, custom homes and site characteristics of Hansen Ranch. The following design and site criteria will establish a consistent direction and level of quality while providing reasonable flexibility in expressing the individual character of the custom homes. B. Architecture: 1) Architectural massing should include articulation of wall planes, projections and recesses to provide shadow and depth, multiple forms and masses. Unarticulated• vast expanses of wall surface and "box like" buildings without horizontal or 'vertical wall articulations would be inappropriate. 2) Provide consistency with existing production units by using materials and colors from production palette or those that are compatible. 3) Roof materials may be flat tile, slate, fire rated shingles or shakes acceptable to the City of Dublin. 4) The garage door should appear to be recessed into the walls. Garage doors should be sectional. 5) The incorporation of balconies and decks into or within the building form is encouraged for both practical and aesthetic value. Balconies should be integrated to break up large wall masses, offset floor setback and add human scale to buildings. Elevated decks should be skirted to grade. C. Building Site: 1) Building siting, height, and scale should respond to the terrain. 2) The building should be split in levels which terrace up or down the slope to keep floor levels close to natural grade., 3) Down slope or rear elevations with high visibility should be kept low. ATTACHMENT H PAGE 97 OF /av Custom Lot Design Guidelines Page Two C. Building Site (Continued): 4) Pony walls or skirt walls between a floor level and the natural grade below should be a maximum of 10 feet in height. 5) Whenever possible, buildings should be sited to preserve and to avoid disturbance to existing trees of 8 inch or larger in caliper. 6) Buildings should be sited to preserve drainage patterns if possible. 7) Buildings should be designed to minimize bulkiness on hillside terrain. Recesses, overhangs, and the play of light and shadow can further reduce mass and add interest, variety, and human scale to the building facade. 8 Decks should be terraced and should have a maximum 10 feet height between the deck surface and natural grade. Deck must have skirting. D. Landscape Design: 1) Landscaping in front yards should be designed to be similar in appearance, in design and materials, to that in adjacent properties within Hansen Ranch. 2) Vegetation should be used to provide some screening of skirt walls under or behind decks and other downslope walls. 3) Landscape design should feature trees to be preserved. 4) Landscape design, including forms, materials and planting design, should be compatible with the forms and patterns of open space vegetation and that of adjacent properties within and beyond Hansen Ranch.
