(A-2) (ZA: N-16) (CT 3383.02) (Parcel #138-170- 008) II. RECOMMENDATION Staff recommends the Planning Commission approve SUB 7647 contingent on the Board of Supervisors approval of Rezoning #2974-RZ and recommend approval of 2974-RZ to the Board of Supervisors. III. GENERAL INFORMATION A. General Plan Land Use Designation: The subject property is designated Single Residential-Very Low Density. The proposed subdivision is consistent with the General Plan. B. Current Zoning: A-2 - Agricultural District; 5 acre minimum. C. Requested Zoning: R-40 - Single Family Residential District. D. CEQA Status: A Negative Declaration was prepared for the project after completion of a Burrowing Owl Study and hydrology analysis of Walker Creek. The Burrowing Owl Study concluded that the subject property is poor habitat for the species and the species is absent from the site. Information provided by the applicant's engineer has concluded the creek is adequate to accept the run-off from the subject property. 2 IV. AGENCY COMMENTS A. Health Services Department: See attached. B. Building Inspection Department: No comment. C. California Archaeological Inventory: No study is recommended. D. Contra Costa County Fire Protection District: Comments are attached. E. Central Contra Costa Sanitary District: Comments are attached. Annexation is required before the proposed connection to the District sewer system can be allowed. The site is in the District's Sphere of Influence. F. City of Walnut Creek: The subject property is directly adjacent to the Flood Control District surplus property, with the potential for development of 32 single family residential lots. The City is requesting the circulation design for the subject property be considered in conjunction with the Flood Control Property. The City has indicated their preference for a loop road through the property from North Gate Road, connecting with the Flood Control property at the subject property's western boundary. G. Public Works Department: The attached conditions of approval based on the December, 1991 tentative map include road and drainage requirements. The applicant should be fully aware of the County Subdivision Ordinance Code requirements as they pertain to this development. V. BACKGROUND Subdivision 7647 was heard by the Planning Commission on October 8, 1991 at which time the applicant agreed to file the rezoning application as required by the North Gate Specific Plan. Subsequently, the item was continued indefinitely. The North Gate Specific Plan ("Specific Plan") was adopted by the Board of Supervisors on June 25, 1992. The Specific Plan was a joint planning effort between the City of Walnut Creek and Contra Costa County. Preparation of the Plan has led to the creation of new policies and regulations for the preservation and future development of the North Gate area. The North Gate area is presently a transition between the agricultural preserve/open space land and very low density single family development and, therefore, constitutes a semi-rural character. The premise of the Plan is for the area to remain primarily semi-rural and support residential, equestrian and recreational activities. 3 VI. STAFF ANALYSIS A. Subdivision Design: The subject property is designated Single Family Residential-Very Low Density on the North Gate Specific Plan, with a density range of 0.2 to 1 .0 units per acre. This land use designation is assigned to those properties in the Specific Plan area under private ownership with slopes less than 15%. A minimum lot size of 40,000 square feet is acceptable. The proposed subdivision consists of parcels ranging in size from 40,000 to 43,133 net square feet, which is consistent with the Specific Plan. B. Residential Design Criteria: The Specific Plan requires homes adjacent to North Gate Road to be single story, no higher than 20-feet with a setback of 40-feet from the edge of right-of-way and face North Gate Road. The height limit for all other residential structures shall be two stories, no higher than 25-feet. The applicant will be required as a condition of project approval to receive design approval from the Zoning Administrator prior to issuance of building permits. C. Oak Trees Removal: Construction of the project access will require the removal of one mature oak tree, approximately 18 - 20 inches in diameter located in the middle of the proposed cul-de-sac. Staff has reviewed the possibility of relocating the road to preserve the tree, however, a variance to lot size for Parcels 4 and 5 would be required in addition to a poorly configured road. Staff would recommend removal of the oak tree with a replanting ratio consistent with the City of Walnut Creek's Tree Preservation Ordinance. In summary, Walnut Creek requires the applicant to hire a certified arborist to determine the monetary value of the tree. The applicant is then required to do replacement tree planting to said dollar amount. All replacement plantings shall be completed and verified prior to issuance of the first building permit. D. Response to the City of Walnut Creek: The City is requesting a loop road connect the Flood Control property and the subject property at its western boundary, permitting efficient access to the proposed emergency vehicle access at the northwest corner of the Flood Control property. North Gate Road can be considered a long cul-de-sac, with one ingress and egress, via Oak Grove Road. Staff has reviewed the City's concerns and finds that alternative access through Mt. Diablo is provided and the creation of the loop road would require substantial variances to lot area for lot four, which is in direct contradiction with the North Gate Specific Plan, or the elimination of Lot 4 entirely and is not a reasonable request for this subdivision. Furthermore, revised comments from the Fire District specifically indicate that an emergency vehicle access between Lots 3 and 4 is not required. 4 E. Water and Sewer Service: The applicant is proposing individual septic systems and water wells for the subdivision. The North Gate Specific Plan requires that all-new residences be connected to public sewer and public water supply. The property will require annexation into the Contra Costa Water District and Central Sanitary District. As a condition of project approval, the applicant will be required to provide evidence to the Zoning Administrator that an urban service boundary reorgani- zation has been completed through the Local Agency Formation Commission (LAFCO), which will include the formation of a police service district. F. Fees: The project was deemed complete on March 19, 1992. The project will be required to pay all fees in place on that date. G. Seismic Zone: The subject property is southwest of the current Alquist-Priolo Zone. The subject property and all the properties west of North Gate Road are scheduled to be included in the expansion and will become effective July 1, 1993. The applicant will be required to submit a geologic report prepared by a registered geologist for review and approval of the County prior to filing the final map on. the hazard of surface fault rupture with recommendations for construction of the residences. In the event that the study identifies a fault rupture on the property, the size of the proposed parcels appear to be large enough to accommodate any necessary development restrictions without significantly affecting the proposed development. H. Rezoning: The proposed rezoning is required to provide consistency with the County General Plan and the North Gate Specific Plan. The rezoning request to single family district complies with the County General Plan and North Gate Specific Plan. DD/aa RZXIX/2974-RZ.DD 4/2/93 AD =µ co 7.00 <f� ci 4P $ ,.

City Of r% Own June 12, 1992 Ms. Debbie Drennan Community Development Department Contra Costa County 651 Pine Street Martinez, CA 94553-0095 SUBJECT: Rezoning/Subdivision Proposal Applicant: E. P. Madigan & Son, Inc. We have reviewed the proposed rezoning and subdivision proposal for the five acre site adjacent to the Flood Control District surplus property. While we have no objections to the rezoning request from A-2 to R-40, we do have concerns about the proposed site plan. The plan shows lot sizes, but does not indicate whether these are gross or net. Lot sizes should be at least 40,000 square feet net and should not include any portion of the roadway. With net lots of 40,000 square feet, could the applicant still subdivide the site into 5 lots? We are also reviewing proposals for various subdivision options for the adjacent Flood Control District Surplus property. In our comments to the District, we have indicated our preference for a loop road through the property from North Gate Road. The loop road design could be better achieved if this property were considered along with the Flood Control District's site. The applicant should be encouraged to develop his property in concert with the Flood Control District to ensure a better circulation design for the area.

MADIGAN & SON, Inc. 5528 Glenbrook Drive Oakland, CA 94618 SUBJECT: The status of the burrowing owl on the 5 acre parcel at 1225 North Gate Road, Walnut Creek, California. The burrowing owl (Athene cunicularia) is a California Department of Fish and Game Species .. of Special Concern , Priority 2 . Although not legally protected by the California Endangered Species Act, 1984, its numbers have been declining over the past decade, and thus it is accorded special consideration in all reviews of potential development properties which the Department undertakes. - This species is unique among owls in that it is diurnal and also uses the abandon burrows of the California ground squirrel as nesting site. These two factors detection of this owl far easier than the other nocturnal members of this group. Even when the bird may be temporarily absent from a site, the presence of ground squirrel burrow systems can still be note along with such sign as bird excrement and remains of small rodent, lizard, and large insect kills near a burrow entrance, all of which indicates current use by burrowing owls. The project site was surveyed for owls on May 20, 1992, a date when burrowing owl nesting is well under way in the greater Bay Area. No burrowing owls were observed during a one hour inspection with binoculars of the site. In addition, no ground squirrel burrows or any other comparable size burrow systems were detected during a walking survey of the area. The lack of both items on this site can be directly attributed to the current condition of the land. Approximately three fourths of the site had been disced for weed control- earlier in the year, and part of that area is now being used as an open ground: horse corral . A small area adjacent to the house on the western edge of the site still supports a dried crop of annual grasses and forbs, but this is within the greater yard area of the residence and is patrolled by the renter's dog. All of the above factors create a most inhospitable habitat for the burrowing_ owl , and hence its absence .on the site. Because of the discing and horse presence, the area is also a veiy poor potential foraging site for this species. Given these findings, it is my professional opinion that additional development on the 5 acre parcel at 1225 North Gate Road, Walnut Creek, California, would in no manner impact the burrowing owl population in the greater project site area.

LOC.: 76C1 AND 76D1 The above referenced project has been reviewed by this office. We do not know from the information that has been provided to us whether the one acre parcels will be served by septic tanks or connect to the District's sewer system. This letter provides current requirements for connecting to the District's sewer system in the near future. 1 . SEWER SERVICE AVAILABILITY AND GENERAL DISTRICT REQUIREMENTS 1 .1 The project site is within the CCCSD sphere of influence, but annexation is necessary before sewer service can be provided. Annexation will require the approval of both the CCCSD Board of Directors and the Local Agency Formation Commission (LAFCO). This issue must be addressed during the CEQA process. 1 .2 The plans submitted for District review do not show the proposed project sewers. The developer should be aware that District policy requires gravity sewers in preference to pumped systems and the location of public sewers in public streets rather than in off-street locations to the extent possible. Variances from this policy are discouraged. However, the District will consider alternatives on a case-by-case basis where the project engineer justifies such alternatives to the District's satisfaction. Recycled Paper Contra Costa County Page 2 November 13, 1991 1 .3 Specific requirements are: Gravity Service. Sewers are to be designed to operate underrg avity flow to the District's existing sanitary sewer system. The use of sewage pumps for individual lots will not be permitted unless it is economically impractical to construct a main sewer to provide gravity service. Section 4-01 .A.10.b of the District's Standard Specifications, 1986 Edition, provides criteria for allowing the use of sewage pumps at individual lots. Location in Streets. As a minimum, an eight-inch public sewer must be extended by the developer to serve each parcel (residential or commercial lot, townhouse unit, condominium building, or apartment complex, as appropriate). New sewer systems are to be designed with the maximum amount of public sewers located in streets. If public sewers proposed for this project are to be located in an off-street location, the project engineer must justify such location to the satisfaction of the District. Easements. An exclusive public sewer easement must be established over the alignment of each public sewer in an off-street or private street location to provide access for future maintenance. The following criteria are used to determine the public sewer easement width: • The sewer easement width shall be 15-feet where the public sewer is less than 12-inch in diameter and the depth is 9-feet or less. • The sewer easement width shall be 20-feet where the public sewer is 12-inch and larger in diameter or the depth is greater than 9-feet. 0 If new public sewers are being installed across properties where existing improvements will remain in place adjacent to the new public sewers, sewer easement width may be reduced at the discretion of the District but in no case can the width be less than 10-feet. In addition, all-weather access for the District's maintenance vehicles to all manholes and rodding inlets in off-street locations is required. All-weather access typically consists of a ten-foot wide cross section with a surface course of turf-block, two inches of asphalt concrete, or other equivalent all- Contra Costa County Page 3 November 13, 1991 weather surface acceptable to the District, over six inches of aggregate base. The use of sanitary sewer easement surfaces shall be limited to paving, shrubbery, gardens, and other landscaping, excluding trees. Parallel surface drainage ways and permanent structures including, but not limited to, buildings, swimming pools, decks, and retaining walls are not permitted within the easement area. Public Sewer Extension The nearest available public sewer is approximately 4,000 feet away in North Gate Road. This sewer is under construction, but the District has not accepted the sewer. The sewer must be accepted by the District before this project can connect to the public sewer 'system. Since the District is not constructing the new downstream public sewer, the developer for this project is responsible for scheduling completion of construction so this project can connect to the public sewer system. In addition, the developer will be responsible for constructing approximately 4,000 feet of public sewer in North Gate Road. 2. SOURCE CONTROL REQUIREMENTS The District has reviewed this project for source control requirements. Base wastewater flow from this project appears to be domestic wastewater such as from residential, office, or church sources. Specific source control requirements are normally not applicable to domestic wastewater. However, materials such as gasoline, oil, sand, paint, pesticide residues, or other toxic substances are prohibited from being introduced into the District's sewer system. 3. SEWER CAPACITY The District has completed a capacity study for the existing sewer system downstream of the proposed project. District facilities do not have adequate flow carrying capacity under the District's current design criteria for ultimate conditions. Improvements to correct the deficiencies are in the District's Capital Improvement Plan. Improvements to the District's existing facilities that are required as a result of new development will be funded from applicable District fees and charges. The developer will be required to pay these fees and charges at the time of connection to the sewer system. 4. PRIVATE SEWERS The proposed project includes side sewers. A side sewer is defined as a private sewer which is owned and maintained by the property owner and which connects Contra Costa County Page 4 November 13, 1991 the plumbing system of the building to the main sewer. The side sewer begins at the point of connection to the building plumbing system two feet outside the foundation line or building wall and terminates at the point of connection to the main sewer. District policy requires that the developer be responsible for installation of the side sewer and the property owner be responsible for operation and maintenance of the side sewer. District review of the design and inspection of the work on the side sewer shall in no way constitute our acceptance of any responsibility for maintenance or damage to property due to construction and subsequent operation and maintenance of the side sewer. The design intent of• the typical side sewer details, included in the CCCSD "Standard Specification," 1986 Edition, and presented in Sections 32-43 through 32-48, inclusive, is to reduce the amount of rainfall and groundwater that will infiltrate the sewer, thereby avoiding unnecessary pumping and treatment costs. The typical side sewer details are not intended to meet the geotechnical, structural, or drainage requirements of special situations. 5. HILLSIDE AND CREEK AREA POLICIES The District has a Hillside and Creek Area Sewer Policy which addresses the design and installation of sewers in hillsides or unstable areas. The requirements of this policy must be followed when construction plans are prepared. For your convenience, a copy of the policy is enclosed. The Sanitary District must review and approve any construction plans involving work on the public sewer system prior to the developer's applying for a building permit. The District's Permit Section will receive and process the construction plans. Sincerely, Jack H. Case Associate Engineer JHC/vh Enclosure cc: E. P.
