ADJOURNMENT (Over for Procedures Summary) _ CITY OF DUBLIN PLANNING COMMISSION AGENDA STATEMENT/STAFF REPORT Meeting Date: October 17, 1988 TO: Planning Commission FROM: Planning Staff 1 SUBJECT: PA 88-054 Dublin Security Storage Conditional Use Permit for a 35' tall freestanding sign at 6005 Scarlett Court GENERAL INFORMATION: During the Staff's review of this application, it was discovered that one of the Applicant's current site uses (Ryder truck rental) has been established without obtaining a City approved use permit and that the previous use permit (PA 86-060) which allowed for rented space of outdoor storage for private vehicle storage and expansion of the mini-storage operation lapsed in August 1988. Staff recommends that this item be continued to allow Staff an opportunity to work with the Applicant and property owners/operator in submitting additional permit applications for Commission consideration concurrently with this application. Upon submittal of the additional information the Staff will reschedule and renotice the applications for a future public hearing. The Staff has reviewed this matter with the Applicant who has submitted a letter (attached) in agreement with the continuance. RECOMMENDATION: FORMAT: 1) Open public hearing and hear Staff presentation. 2) Take testimony from Applicant and the public. 3) Continue Public Hearing. ACTION: Staff recommends the Planning Commission continue PA 88-054 Dublin Security Storage, with Staff to renotice the application. COPIES TO: Applicant 3 Owner .

APPLICABLE REGULATIONS: The Dublin General Plan establishes policies and standards to control land use and development within this area. Section 8-31.0 (Planned Development District Intent) states, in part, that Planned Development Districts are established to encourage the arrangement of a compatible variety of uses on suitable lands in such a manner that the resulting development will: a) Be in accord with the Policies of the General Plan of the City of Dublin; b) Provide efficient use of the land that includes preservation of significant open areas and natural and topographic landscape features with minimum alteration of natural land forms; c) Provide an environment that will encourage the use of common open areas for neighborhood or community activities and other amenities; d) Be compatible with and enhance the development of the general area; e) Create an attractive, efficient and safe environment. Section 8-1.2 of Chapter 1, Title 8 (Subdivision Ordinance Intent) states, in part, that it is the intent of this Chapter to promote the public health, safety, and general welfare; to assure in the division of land consistency with the policies of the General Plan and with the intent and provisions of the Zoning Ordinance; to coordinate lot design, street patterns, rights-of- way, utilities and public facilities with community and neighborhood plans; to assure that areas dedicated for public purposes will be properly improved initially so as not to be a future burden upon the community; to preserve natural resources and prevent environmental damage; to maintain suitable standards to insure adequate, safe building sites; and, to prevent hazard to life and property. ENVIRONMENTAL REVIEW: The City proposes to adopt an Environmental Impact Report (EIR) which finds the proposed project may have a significant impact on the environment. NOTIFICATION: Public Notice of the September 19, 1988 hearing was published in The Herald, mailed to adjacent property owners, and posted in public buildings. BACKGROUND/ANALYSIS This item was continued from the October 3, 1988 Planning Commission meeting at which time the Commission received comments from the Applicant, the Public and Staff. At that meeting the Commission considered and discussed the revised plan presented by the Applicant and directed Staff to prepare resolutions for Planning Commission consideration at the October 17, 1988 Commission Meeting. The three Planning Commissioners present at the October 3, 1988 Commission meeting unanimously directed Staff to prepare a resolution with favorable recommendations concerning: -2- 1. Adequacy and completeness of the Final EIR. 2. Amend General Plan to incorporate entire Hansen Hill Ranch project within the primary planning area. 3. Amend General Plan to delete Areas 5,6 and 7 from Table I and Figure 4 of the General Plan. 4. Amend General Plan policy and map with regard to Hansen Drive extension. 5. Amend General Plan to include alternate roadway serving Hansen Hill Ranch site (Valley Christian Center access road) and designate as a collector street. 6. Amend General Plan to include policy establishing level of service D as maximum level of service acceptable. 7. Amend General Plan to include policies requiring fire protection buffer zone around perimeter of residential development which interface with open space lands. 8. Amend General Plan to include policies related to open space maintenance. Two Planning Commissioners indicated they were in favor of the Applicant's proposal for density and location of development: Applicant's Proposal 1) Open Space/Stream Corridor 2) Single Family Residential (.9 - 6.0 DU/Acre) 3) Medium Density Residential (6.1 - 8 DU/Acre) One Planning Commissioner expressed a preference for Staff's recommendation on maximum unit yield and a preference for the Applicant's proposal on location of development. Approval of Staff's recommended unit yield in combination with the Applicant's proposed land use designation location would result in the following density range: Density Acres DU/AC Unit Yield Medium Low Density 5.5 ac (gross 6.3 ac) 6.1 to 8 38 to 50 Single Family Low Density 71.5 acres .4 to 1.8 28 to 129 Total Unit Yield 66 to 179 The Applicant is proposing a maximum unit yeild of 245 units on 147 acres. The Applicant's General Plan Amendment proposes the following land use designations and approximate acreage: (See Attachment 30 for location of proposed land use designations): Applicant's Proposed Land Use Designations Acres Density Unit Yield Open Space 70+ ac -0- -0- Medium Density 5.5+ ac (gross 6.3 ac) 6.1 to 8 du/ac 38 to 50 Single Family 71.5+ ac 9 to 6 du/ac 64 to 429 Total Unit Yield 102 to 479 The Applicant's current proposal reduces grading and residential development within Area 1 and a portion of Area 3. Residential Development and a significant amount of fill is still proposed within Area 2 (see Attachment 15). Staff recommends the following land use designations and approximate acreage: (See Attachment 6 for location). -3- Staff Recommendation Unit Yield Based on Density Gross Acre Open Space 96+ ac Medium Low Density 5.5+ ac (gross ac 6.3) (6.1 to 8 du/ac) 38 to 50 du Single Family Low Density 46+ ac (.5 to 2.8 du/ac) 23 to 129 du Total Unit Yield 61 to 179 Approval of Staff's recommendation on density and land use designation would result in a total unit yield range for the site between 61-179 dwelling units. Consistent with existing General Plan Policies Staff's recommendation eliminates residential development within oak/bay woodland areas, 30% slope areas and riparian habitat areas, and recommends open space designation for these areas. It is Staff's recommendation and interpretation that the proposed General Plan Amendment requesting residential land use designation within Areas 2 and 3 (Attachment 15) is inconsistent with existing General Plan policies relating to open space preservation, oak woodlands and 30% slopes, in particular policies: 3.1A Preserve oak woodlands, riparian vegetation, and natural creeks as open space for their natural resource value. 3.1B Maintain slopes predominately over 30 percent (disregarding minor surface humps or hollows) as permanent open space for public health and safety. 3.1C Continue requiring reservation of steep slopes and ridges as open space as a condition of subdivision map approval (pg. 15). Approval of the Applicant's proposal to allow 66 dwelling units in areas which the existing General Plan policies would not allow development in will necessitate a policy amendment to allow an exception to policies 3.1A, 3.1B, and 3.1C if the finding is made that the development will meet other overriding General Plan policies such as Policy 2.1.1A. "2.1.1A. Encourage housing of varied types, sizes and prices to meet current and future needs of all Dublin residents." Exhibit C contains a policy addressing this issue. Staff recommends the Commission adopt the Resolutions 1) recommending City Council certification of the EIR as complete and adequate with findings and a statement of overriding considerations (Exhibit A) and 2) recommending adoption of the General Plan Amendments relating to the primary planning area, Hansen Drive extension and alternate roadway, maximum acceptable level of service (LOS), fire protection buffer zone, and open space maintenance and recommending land use designation and density for the Hansen Hill Site (Exhibit B). Should the Planning Commission wish to recommend approval of the Applicant's proposal, the Planning Commission should adopt Exhibit C. Should the Planning Commission wish to modify the density on either the Staff's recommendation or Applicant's proposal, the Planning Commission should indicate so to Staff. 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 Resolutions recommending City Council approval of EIR and General Plan Amendment.

CEQA Compliance: That the Environmental Impact Report (EIR) is adequate and complete and has been prepared in compliance with the California Environmental Quality Act (CEQA) the State CEQA Guidelines, and that the Commission has considered and reviewed the information contained in the EIR. 2. Significant Adverse Environmental Impacts: That the significant Adverse Environmental Impacts identified in the EIR (See summary Page 1-2 through 1-11) will be mitigated to a less than significant level by application of the mitigation measures identified in the EIR summary and incorporated by reference as Attachment A-1. BE IT FURTHER RESOLVED THAT THE Dublin Planning Commission recommends the City Council adopt the following findings and statement of overriding considerations regarding significant environmental effects of the Hansen Hill Ranch General Plan Amendment PA 87-045: 1. Extensive Grading: Development of the project will result in extensive grading on the site. The extensive grading will result in an unavoidable adverse impact to a significant ravine and woodland area as the ravine is proposed for fill of 50 ft. depths. Findings: The adverse environmental impacts associated with the extensive grading (cut & fill) is considered "acceptable" as the benefit of balancing cut and fill on site (eliminating export of fill) outweigh the unavoidable adverse environmental impact of filling significant ravine and woodland area. Anep,FT o.-US..k -u ac.Resoi,l; , op Er!, 2. Oak/Bay Forest and Riparian Corridor Impact: Placement of fill material and cutting of slopes within and under the tree canopy will reduce habitat value and result in removal or potential damage to individual trees. The largest area of oak/bay woodland removal occurs within an approximate 6 acre area containing oak/bay woodland and drainage swale/ravine. The most extensive riparian corridor area on site disturbed by the project occurs in the area at which the riparian corridors of Martin Canyon Creek and the largest tributary on site meet. Findings: The adverse environmental impacts to the oak/bay woodland and riparian habitat corridor is considered "acceptable" as the benefit of balancing cut and fill on site, outweighs the unavoidable adverse environmental impacts of eliminating a significant ravine and woodland area through the placement of fill material, and the benefit of providing vehicular and emergency access on site, outweighs the adverse environmental impacts to the oak/bay woodlands.

APPLICABLE REGULATIONS: The Dublin General Plan establishes policies and standards to control land use and development within this area. Section 8-31.0 (Planned Development District Intent) states, in part, that Planned Development Districts are established to encourage the arrangement of a compatible variety of uses on suitable lands in such a manner that the resulting development will: a) Be in accord with the Policies of the General Plan of the City of Dublin; b) Provide efficient use of the land that includes preservation of significant open areas and natural and topographic landscape features with minimum alteration of natural land forms; c) Provide an environment that will encourage the use of common open areas for neighborhood or community activities and other amenities; d) Be compatible with and enhance the development of the general area; e) Create an attractive, efficient and safe environment. Section 8-1.2 of Chapter 1, Title 8 (Subdivision Ordinance Intent) states, in part, that it is the intent of this Chapter to promote the public health, safety, and general welfare; to assure in the division of land consistency with the policies of the General Plan and with the intent and provisions of the Zoning Ordinance; to coordinate lot design, street patterns, rights-of- way, utilities and public facilities with community and neighborhood plans; to assure that areas dedicated for public purposes will be properly improved initially so as not to be a future burden upon the community; to preserve natural resources and prevent environmental damage; to maintain suitable standards to insure adequate, safe building sites; and, to prevent hazard to life and property. ENVIRONMENTAL REVIEW: The City proposes to adopt an Environmental Impact Report (EIR) which finds the proposed project may have a significant impact on the environment. NOTIFICATION: Public Notice of the August 23, 1988 and August 24, 1988, hearing was published in The Herald, mailed to adjacent property owners, and posted in public buildings. BACKGROUND/ANALYSIS This item was continued from the August 1, 1988 Planning Commission Meeting at which the Commission established two Study Sessions; one for August 23rd and one for August 24th and a Field Trip to the project site on August 20, 1988. The purpose of the August 20th Field Trip was for the Commission and the public to review on site the three areas in which Staff's recommendation for development differs from the Applicant's proposal (see Attachment 15, August 1, 1988 Staff Report). The purpose of the August 23rd and August 24th Study Sessions is for the Planning Commission to review and gather information on the Hansen Hill Ranch project and to provide direction to Staff and the Applicant. The Planning Commission may decide to 1) conduct the Study Sessions without public comment -2- or testimony resuming public input at a regularly scheduled public hearing or 2) conduct the Study Sessions accepting public comment during the Study Sessions at the Commission's discretion. In conducting the Study Session, Staff recommends that the Planning Commission address the two key issues of 1) where to develop and 2) how much to develop: 1. Where to Develop: The Planning Commission should recommend what areas on the site have potential for reasonable and desirable development. The Planning Commission should give consideration to the environmental constraints and General Plan goals of the City in conjunction with the needs of the Applicant. 2. How Much to Develop: The Planning Commission should recommend what amount and type of development is potentially reasonable and desirable. The Planning Commission should recommend the General Plan land use designation and density range, so that the number and type of dwelling units can be determined. In addition to the issues of where to develop and how much to develop, the Planning Commission should address the other issues identified in the previous Staff Reports and any other issues raised by the Planning Commission. The additional issues include: 1. Adequacy and completeness of the Final EIR. 2. Land Use Designation - Staff recommends three General Plan land use designations for the Hansen Hill Ranch site, as generally depicted in Attachment 6: a. Open Space/Stream Corridor b. Low Density Single-Family Residential (.5 - 2.8 D.U./Acre) c. Medium Density Residential (6.1 - 8 D.U/Acre) 3. Amend General Plan to incorporate entire Hansen Hill Ranch project within the primary planning area. 4. Amend General Plan to delete Areas 5, 6 and 7 from Table I and Figure 4 of the General Plan. 5. Amend General Plan policy and map with regard to Hansen Drive extension. 6. Amend General Plan to include alternate roadway serving Hansen Hill Ranch site (Valley Christian Center access road) and designate as a collector street. 7. Amend General Plan to include policy establishing level of service D as maximum level of service acceptable. 8. Amend General Plan to include policies requiring fire protection buffer zone around perimeter of residential development which interface with open space lands. After the Planning Commission addresses all of the issues, the Planning Commission should direct Staff to prepare a resolution incorporating the Planning Commission's recommendations. Prior to making any decisions on the proposed project, the Planning Commission would need to reconvene in its regular meeting format, receive any additional testimony, pose questions, close the public hearing, deliberate, then take action. RECOMMENDATION FORMAT: 1) Open public hearing for Study Session (a non-decision making workshop format) and hear Staff presentation. 2) Discuss and clarify issues and give informal and general direction 3) Continue workshop to specific date, time and place. -3- Attachments REFER TO JULY 18, 1988 STAFF REPORT FOR ATTACHMENTS 1 THROUGH 13.

Tong DUBLIN BANNING Planning Director Dear Mr. Tong, Let me begin by commending you and the planning board for your professional and thorough handling of the Hansen Hill Ranch project. Obviously, with the number of topics discussed, and people talking, it would have been very difficult to note or absorb all that took place during the August 1 meeting. With this in mind I would like to submit the following summary of my comments to the board. Applicable Regulations: Section 8-31.0-Pg. 2 Agenda Statement/Staff Report d) Be compatible with and enhance the development of the general area; e) Create an attractive, efficient and safe environment. Page 5 - Same Staff Report - "Deletion of Hansen Drive Extension/Addition of Alternate Road." The last sentence of the section states "addition of a collector street parallel to Hansen Drive." Page 6 - Item 6 - Same Staff Report - "Amend General Plan to include alternate roadway serving Hansen Hill Ranch site (Valley Christian Center access road) and designate as a collector street. After calling attention to these sections of the staff report I pointed out and showed on the wall map the exact location of the "collector road." According to the plans submitted, and the model layout provided, it will be located directly adjacent to the fence line bordering the Silvergate Highlands Townhouse property. This is on the northeast corner of the proposed project and feeds on to Silvergate Dr. My fellow homeowners and I would like to voice our strongest objection to this "collector road" placement for the following reasons: Health and Safety - of the residents bordering this "collector road." With the construction of 248 units directly adjacent to our property our estimate of 5 trips per day/per unit or 1240 vehicles using these roads. As the location of Silvergate Ave. to the project is much closer to the project than Dublin Blvd. (exiting through Valley Christian Center) the vast majority of vehicles would be using the "collector road" next to our ATTACHMENT 19 4564fr 'Po 8l.O`fs /aAc.t,µtt Ia....e.c. Toxic Emissions - All townhouses along the "collector road" are constructed at an elevation above ground level of 12 to 15 feet. Our major concerns are toxic emissions and noise levels. The basic health of those living directly "abo era street handlig—Tirge numbers of vehicles could be severely affected by breathing emissions (carbon monoxide is one of the most deadly gasses known to man) on a regular basis. This condition is magnified by the fact that a road entering onto Silvergate Dr. must have a stop sign. In other words, every car leaving the project which uses this exit would be required to stop (hopefully), idle until traffic was clear to proceed onto Silvergate, and then apply extra gas to continue onto Silvergate Dr. All these motions of a vehicle increase emissions. (If you would like to test this, stand on any street corner where a stop sign is located that is heavily traveled. Note the air quality - then move down the street to an area which has free moving traffic. The difference is obvious.) Noise - During the meeting I referred to Section 6. Noise, contained in the Environmental Assessment Study and pointed out specifically item 6.3, Policy Review. It's difficult to imagine, given the traffic patterns described above under emissions, that the noise level for residents living in this area will not be higher than the 60 dBA regulation slated in this Section. Please keep in mind the elevation of these homes directly above and to the northeast of this street. It's also a basic fact of nature that our wind pattern carries from West to East. This air flow will also carry both the noise and toxic emissions. Our homes are located on the northeast section of this proposed development. Safety - A brief comment was made concerning the speed of vehicles using Silvergate Dr. Our association will be contacting the city regarding the addition of "stop signs" as the intersection of Silvergate Drive and Rolling Hills Drive. Due to the rise and lowering of Silvergate through our community there are concerns about the ability of autos to stop if necessary for crossing pedestrians or autos. The expected increase in "cross traffic" preceding north on Silvergate from this "collector road" could be dangerous. My final comment referred to Section 10 - Land Use Page 10-12, para. 3, last sentence. "It is not known, however, whether the Silvergate Drive access point could be capable of serving project-generated traffic at a level consistent with maximum buildout potential of 65-542 units." I was a little uncertain what this applied to and, understanding the nature of the meeting not to answer questions, but to take comments, realize it may or may not be directly related to my prior comments. My interpretation was that the staff already is concerned about this "collector road", however didn't have sufficient information to make a conclusion at this time. In closing I would like to reiterate my satisfaction with you and your staff in handling all aspects of this project. While concerns of others relating to landfills, land cuts, trees, fox and even snakes are important, I'm personally concerned with our most valuable asset, the people. Please feel free to contact me concerning this letter or any other aspect of our community. Sincerely, c_A Russell C. Sme :0 rot 6alilvrnlo _. Th.RaOar[el Agency M.eriiorandum C, To 1.

DUBLINKAWK Subject` Draft Environmental Impact Review (DEIR) for the Hansen Hill Ranch Project, Dublin, Alameda County, SCH# 87050527 • Department of Fish and Game (Department) personnel have reviewed the DEIR for the Hansen Hill Ranch Project and have previously been onsite with the project applicant. This project proposes to construct 282 residential units on 147.3 acres of land. We have the following comments: • The document states that the project could adversely affect 22 Thee (36percent) of the oak-bay woodland onsite. This habitat is important and should be preserved, as it provides both food • and cover for a wide variety of wildlife. The Conservation Element of the Dublin General Plan contains a Guiding Policy to protect oak woodlands. The Implementing Policy is to "require preservation of oak woodlands." The project, as proposed, is contrary to the General Plan. Replacement of this vegetative community elsewhere onsite as mitigation may be possible. However, the value of the habitat will not be regained until the planted saplings mature in 30 to 40 years. Also, other habitats would have to be changed in order to create the acreage needed for mitigation. The document states that 11 acres of oak/bay woodland and a drainage swale will be removed by portions of Neighborhoods 5 and 9. Mitigation suggested in the DEIR is that the areas of extensive grading and fill in these two neighborhoods be eliminated from the project and the oak/bay woodlands preserved. Because of the value of this habitat, the Department agrees with the mitigation suggested and recommends that the project be redesigned in the areas mentioned. The proposed project also will impact 0.3 to 3.5 acres of creekside vegetation, depending on whether a 30 or 100-foot buffer is established along the creek. The document states that the Department recommends a 100-foot buffer. This is to protect the vegetation along the creek and to provide an undisturbed travel corridor for wildlife. A 30-foot buffer is being recommended .in the DEIR for the area behind Neighborhood 1. While this area has been disturbed, it is our opinion that a 30 foot buffer is not adequate. ATTACHMENT 09 r. o? - V %1-cs�s 44 %e., 1441A R0.4.CL. �1 r 1. Projects Coordinator -2- February 3, 1988 Resources Agency 2. Mr. Kevin Galley City of Dublin We concur with the recommendations set forth in the DEIR to preserve and protect the creekside vegetation. These recommendations include: not allowing the building of structures within the buffer; eliminating lots 102-110 and 95-101 so that structures do not back up to the corridor; relocating Creekside Road to the west/ and mitigating for trees removed "on a 3:1 basis. The elimination of lots 95-110 also would preserve additional oak/bay woodland. The document states that suitable habitat for the rare Alameda striped racer occurs onsite and that the species may exist there. The snake was not observed during the one day field survey which was conducted. This type of survey is not adequate to determine the presence or absence of this species. The snake is a secretive animal and rarely is seen, even in areas where it is known to exist in some numbers. Chaparral near riparian areas, such as exists onsite, appears to be preferred habitat for this species. One of the prime factors affecting sensitive species is loss of habitat. The DEIR does not address the impacts to this habitat or to the snake, nor does it pffer mitigation. The Creekside Road crossing would link the project to an emergency access road paralleling the north side of the creek. The document states that this is a preferred access route in terms of reducing impacts to the riparian corridor, rather than a second emergency access road on the south side of the creek. We agree that this is a preferred alternative. Any such road on the south side of the creek would result in increased impacts tc oak/bay and creekside vegetation and the need for increased mitigation. A mitigation measure presented in the Land Use Section of the document recommends that a "pedestrian corridor along the streambank" be created. In order to protect the habitat and prevent human intrusion, we recommend that the pedestrian corridor be placed along the outside edge of the buffer zone.' The document also suggests that "installation and maintenance of a project-size perimeter fence should be required" in order to keep cattle off the site and discourage trespassers. We discourage the construction of such a fence as it would inoede the movement of wildlife. If a fence is required, we recommend that it be of a type that will permit the passage of all wildlife species. Some designs which would be acceptable include barbed wire, smooth wire, or Wooden rail. 1 . Projects Coordinator -3 - February 3 , 1988 Resources Agency 2 . Mr. Kevin Galley City of Dublin The document correctly states that a Streambed Alteration Agreement with this Department will be necesary for any work done in the creek. The U. S . Army Corps of Engineers (Corps) also has jurisdiction over creeks under Section 404 of the Clean Water Act. If the applicant has not done so, we recommend that the Corps be contacted in order tc determine if they wish to exercise their jurisdiction over Martin Creek and require a permit. Footnotes 6 on page 3-30 and 3 on page 3-36 should be changed to reflect the correct name of the wildlife biologist that was contacted for this project. She is listed as a contact person below. • The Mitigated Alternative appears to alter the proposed project based on the mitigations suggested in the text. This alternative would avoid development on the ridgeline along the southwest corner and the oak woodland areas in the central area and northwest corner where extensive cut and fill was proposed. Mitigation in the Vegetation section calls for the elimination of lots 95-101. According to Figure 4-1, this suggestion has not been included in the Mitigated Alternative. If this mitigation, as well as the others included in the DEIR, is incorporated in the design, we would consider the document to be adequate for compliance with California Environmental Quality Act. Department personnel are available to address our concerns in more detail .
