Item 4 - EA/TTM 01-02, Jeff Fisk AGENDA REPORT SUMMARY °' �F W"r �F� �n.... �w �'�E{ �IN R{E LO TO: Honorable Mayor and Members of the City Council FROM: James L. Bowersox, City Manag�� INITIATED BY: Niall Fritr, Director of Development Services DATE: July 5, 2005 SUBJECT: Environmental Assessment and Tentative Tract Map (TTM) 01-02, Jeff Fisk, A licant, and Ashton Marshel, Owner; APN 316-071-06. ABSTRACT Approval of this project would subdivide a 5.6-acre property at 12664 Cobblestone Creek Road, within the Rural Residential C zone, into five (5) one-acre residential lots and a lettered lot to contain a public sewer pump station. The property is partially located within the floodway and floodplain of Beeler Creek. The project would result in the upgrade of the existing water main and the extension of a new sewer main to the site and the Cobblestone Creek neighborhood. Cobblestone Creek Road and Cobblestone Creek Trail would be widened to 20 feet. ENVIRONMENTAL REVIEW An Environmental Initial Study was completed on the project and it was determined that there will be no significant environmental effects from the project as long as impacts are mitigated by recommended conditions of project approval. The approval of a Mitigated Negative Declaration is therefore recommended. FISCAL IMPACT None. ADDITIONAL PUBLIC NOTIFICATION AND CORRESPONDENCE Public notice was published in the Poway News Chieftain and mailed to 33 property owners within 500 feet of the project site. RECOMMENDATION It is recommended that the City Council approve the Mitigated Negative Declaration and TTM 01-02, sub�ect to the conditions in the attached ro osed Resolution.

Bowersox, City Manager�� INITIATED BY: Niall Fritz, Director of Development Services� Patti Brindle, City Planner � �" Oda Audish, Associate Planner� DATE: July 5, 2005 SUBJECT: Environmental Assessment and Tentative Tract Map (TTM) 01-02; Jeff Fisk, Applicant, and Ashton Marshel, Owner; APN 316-071-06 BACKGROUND The applicant proposes to subdivide a 5.6-acre property at 12664 Cobblestone Creek Road, within the Rural Residential C (RR-C) zone, into five(5)one-acre residential lots and a lettered lot to contain a public sewer pump station (Attachments B, C and D). The property is located at the eastern terminus of Cobblestone Creek Trail and is accessed from Poway Road via Cobblestone Creek Road and a bridge that crosses Poway Creek near the western City limit. A 2,000-square-foot barn currently occupies the northeast corner of the property, which is proposed to be Lot 2 of the subdivision. The remaining site has been disturbed and contains horse corrals and ornamental plants, except for isolated patches of low-quality Diegan Coastal Sage Scrub vegetation that are scattered on the northern and southern portions of the property. The northeast and southeast corners of the project site are located within the 100-year floodway and floodplain of Beeler Creek. Surroundina Land Use— The property is bounded by single-family residential homes to the north, east, and west. An easement providing access to the neighboring property to the east bisects the property. The proposed subdivision would continue to provide access to this neighboring property. A passive Open Space easement granted to the City in 1982 is located to the south of the property. Neighborhood Meetins� —A Neighborhood Meeting was held on April 3, 2003, to review the subdivision proposal with property owners within 500 feet of the project site. About 20 residents attended the meeting. The neighbors were generally in favor of the project. Issues discussed included the creation of a new pedestrian bridge adjacent to the existing bridge across Poway Creek, trails, and protection of the neighborhood character. 2 of 64 July 5, 2005 Item # � Agenda Report July 5, 2005 Page 2 At the time of the Neighborhood Meeting, the applicant was proposing to construct a water and sewer main from Poway Road to the Cobblestone Creek neighborhood and the project site across Poway Creek. The mains would be attached to the existing bridge, which is privately owned, or to a new pedestrian bridge. Some neighbors were concerned about assuming liability with the mains attached to the existing bridge or that a new pedestrian bridge could encourage more non-resident pedestrian traffic in the neighborhood. Since the Neighborhood Meeting, the applicant has learned that he is unable to obtain one of the easements required for the sewer main to cross Poway Creek. As a result, the alignment of the sewer main improvements and the method by which the water and sewer mains would be crossing the creek have been changed, as discussed further below. Also, neighbors generally favored adding a connection from the neighborhood to the City's existing trail system to the east. Finally, a few neighbors also wanted to ensure that the extent of the improvements to both Cobblestone Creek Road and Trail would preserve the rural character of the roads and neighborhood. FINDINGS Proiect Description — The applicants propose to subdivide the subject property into five (5) residential lots. The project complies with City development standards for the RR-C zone as shown in the following Zoning Table. ZONING TABLE Net Lot Size Lot Depth Lot Width Lot Depth/Vllidth Ratio RR-C 1 AC 150 ft. 110 ft. 3:1 maximum Standard Lot 1 1.10 AC 200 ft. 220 ft. 0.9:1 Lot 2 1.09 AC 260 ft. 190 ft. 1.3:1 Lot 3 1.03 AC 260 ft. 170 ft. 1.5:1 Lot 4 1.01 AC. 260 ft. 160 ft. 1.6:1 Lot 5 1.00 AC 260 ft. 164 ft. 1.6:1 The proposed project would enhance the existing and provide for new infrastructure to the Cobblestone Creek neighborhood consisting of improved fire access and protection facilities, upsizing the existing water service, adding sewer service, and adding a trail link, as further discussed below and as shown on Attachment E. Access Improvements - The site is accessed from Poway Road via two private streets, Cobblestone Creek Road and Cobblestone Creek Trail. The road crosses Poway Creek via an existing bridge. Cobblestone Creek Road is paved with asphalt, as is Cobblestone Creek Trail up to the western limits of the subdivision project site. The proposal would widen Cobblestone Creek Road to 20 feet from the south side of the bridge up to and including, the existing paved portion of Cobblestone Creek Trail (Attachment E). The areas that are to be trenched for the purpose of installing utilities and the existing severely damaged areas of the road would receive additional paving and a slurry coat to the 3 of 64 July 5, 2005 Item # � Agenda Report July 5, 2005 Page 3 satisfaction of the Director of Development Services. The existing gravel section of Cobblestone Creek Trail would be paved to 20 feet in width, and the road would be extended south and be provided with a cul-de-sac. The existing driveway to the barn building, on the subject property, and the neighboring residence to the east would be paved to 20 feet in width. Water Service—The existing water main, serving the Cobblestone Creek neighborhood, extends from Poway Road under Poway Creek to Cobblestone Creek Road, at which point the main follows Cobblestone Creek Road and Cobblestone Creek Trail. The diameter of this line would be increased in size from its existing 4 and 6 inches to 8 inches to provide adequate fire flow to the area (Attachment E). A fire hydrant would be installed within the project area off of the new water main. Sewer Improvements—The Cobblestone Creek neighborhood is served by private septic systems on each lot. Due to the proximity of the proposed subdivision to the creek, the project site would not be permitted to have a septic system. The proposal includes providing sewer service to the project site by connecting to an existing sewer main to the east within Boulder View Drive, at a distance of approximately 2,000 feet (Attachment E). The sewer would have to be pumped via a force main to the existing sewer main within Boulder View Drive because the project site is located at a lower elevation than the existing sewer main. The force main would originate at a sewer pump station, proposed to be constructed on a separate lot (Lot A) within the subdivision limits. Lot A would be dedicated to the City of Poway in fee and the City would assume maintenance responsibility of the pump station. The force main would extend from the proposed sewer pump station to the southern limits of the project site within the existing Cobblestone Creek Trail. The main would then "travel" off-site in an easterly direction along the boundary of the open space property dedicated to the City, under Beeler Creek, and then along an existing dirt service road. The force main would then turn northeast, cross a private, developed property, and ultimately tie into the existing sewer main located within Boulder View Road. It should be noted that the map that created the City's Open Space Easement specifically allows for the installation of public utilities. A separate gravity sewer main would be constructed from the intersection of Cobblestone Creek Road and Cobblestone Creek Trail to the pump station as shown on (Attachment E). A second gravity sewer main would extend from the new Cobblestone Creek Trail cul-de- sac to the pump station. Existing residences in the Cobblestone Creek area could be connected to the new sewer mains for a fee to the City. The applicant has the option to process a reimbursement agreement which would allow him to recoup some of the costs associated with the sewer improvements (gravity and force sewer mains and the sewer pump station) as new connections are made to the sewer mains. 4 of 64 July 5, 2005 Item #� Agenda Report July 5, 2005 Page 4 Trail Imarovement-A trail would be constructed and dedicated to the City from the new Cobblestone Creek Trail cul-de-sac to provide a linkage to the South Poway Trail located within the existing open space lot located to the south of the project site and that connects to Pomerado Road (Attachment E). Utilitv Poles - An existing utility pole would be removed and the existing, and proposed utility connections would be placed underground up to the nearest existing power pole to the east (Attachment E). Floodwav-The 100-year floodway limits from Beeler Creek extend into the project area along the northeast (Proposed Lot 2) and southeast (Proposed Lot 5) corners as can be seen on Attachment B and C. The City's General Plan calls for a 50-foot setback from riparian corridors or a sufficient distance as determined by a qualified biologist to avoid damage to these areas. It should be noted that the biology report did not identify wetland or riparian habitat on-site. An existing residence and accessory building are located within the floodway area between the project site and the actual creek bed to the east. Therefore, a lesser setback from the creek is appropriate The proposed Lot 2, located on the northeast corner of the project site has been previously disturbed and contains an approximately 2,000-square-foot barn structure located approximately 30 feet from the floodway. The structure was approved and built before the adoption of the City's current buffer requirement. The approved grading plans for the barn show that grading occurred up to the limits of the floodway. A concrete slab extending from the barn maintains a 20-foot setback from the floodway. A neighboring residence is located within the floodway, between the project site and the creek channel. It is anticipated that the existing barn would be replaced by a single-family residence in the future. Given the existing development on-site and off-site, it would be appropriate to allow the footprint of a future residence on Lot 2 to maintain the 30-foot setback of the existing barn from the floodway and to allow for a walkway to be constructed around the residence within 24 feet of the floodway. An Open Space Easement would be granted across the 24- foot buffer and its limits marked. No structures or paving would be permitted in the open space lot except for a fence. Landscaping and a permanent irrigation system would not be permitted except for the planting of native riparian species. The proposed Lot 5, located on the southeast corner of the project site, does not contain any structures, but has been previously disturbed with horse corrals. A 50-foot open space buffer from the limits of the floodway would be required on the proposed Lot 5. The buffer would also be in the form of an Open Space Easement as discussed above for Lot 2. Trees - A Tree Inventory Report was completed for the proposed subdivision and associated off-site road and utility improvements. Based on the current project description, there are approximately 151 trees within the project area, consisting of the TTM and the off-site street and utility improvements. Of the 151 trees, approximately 36 trees are Coast Live Oak and 4 trees are native California Sycamores. The native trees are located along the proposed utility lines and road widening, except for approximately 7 trees located on 5 of 64 July 5, 2005 Item # � Agenda Report July 5, 2005 Page 5 the proposed Lot 2. Per the City's Urban Forestry Ordinance, both Coast Live Oak and California Sycamore trees are native to the City of Poway and must be retained unless their removal is absolutely necessary. A Tree Removal Permit approved by the Director of Development Services would be required prior to removing any of these trees. The proposed project will not remove any native trees. Based on a site visit with the City's Arborist, the proposed off-site utilities and road widening would avoid or minimize the impacts to these trees by the method of construction and by having an arborist present to direct the cutting of tree roots when necessary. Furthermore, future development would not impact the native trees located on Lot 2 because these trees are located within the floodway area and therefore are not within a developable portion of the property. A covenant will be recorded on the title of Lot 2 prior to Final Map to notify future property owners that the oak and sycamore trees are native trees and may not be removed unless a Tree Removal Permit has been issued by the City. The remaining 111 trees are non-native and consist primarily of Eucalyptus, Pine, and Palm trees. The majority of the Palm trees have been planted in connection with current and past horticultural use of the site. Given that the site is fairly level and that grading activities should be limited, it is anticipated that only a few of the non-native trees would need to be removed. Except for trees that were planted as part of the horticultural use of the site, trees determined necessary to be removed would have to be replaced in accordance with the City's Urban Forestry Ordinance. It shall be noted that once the site has future owners of the new lots, they can remove the non-native trees without a permit. Required Improvements The proposed project will require completion of the following improvements: • Widening of the existing paved portion of Cobblestone Creek Road and Cobblestone Creek Trail to a minimum of a 20-foot-wide pavement. ■ Extension of Cobblestone Creek Trail to the project site and the construction of a cul-de-sac. • Construction of sewer and water main improvements across Poway Creek and Beeler Creek to the project site. ■ Public waterline, sewer line, and access easement(s). ■ Construction and dedication of a public trail link from the new cul-de-sac to the City's Open Space Easement located to the south of the project site. • Dedication of an off-site sewer easement, with access rights from Boulder View Road to the Subdivision, to the City. ■ Dedication of Lot "A" to the City for the purpose of a public sewer pump station. • Dedication of the floodway area to the City for purpose of public drainage and access. • Access Easement to Lot "A", from the existing private street to Lot "A". ■ Construction of one fire hydrant along the new road. 6 of 64 July 5, 2005 Item # 'T Agenda Report July 5, 2005 Page 6 ■ Undergrounding of one (1) utility pole on-site. ENVIRONMENTAL REVIEW An Environmental Initial Study (EIS) was completed on the project and it was determined that there will be no significant environmental effects from the project, as long as impacts are mitigated by the recommended conditions of the project approval. The approval of a Mitigated Negative Declaration is therefore recommended. The environmental issues are thoroughly discussed in the EIS document (Attachment F). It was determined that, while the project will not have a significant adverse impact on the environment, it could result in potential impacts in the areas of biological resources, hydrology and water quality, and cultural resources. All anticipated project impacts, however, can be mitigated to a level of insignificance. Habitat- The site is not located within the Mitigation Area of the Poway Subarea Habitat Conservation Plan (Poway HCP). The vegetation map for the Poway HCP indicated that the site is developed and has disturbed habitat. A biological report dated March 22, 2005, prepared by Vincent Scheidt, concluded that the site is comprised primarily of a barn structure, ornamental plants, and occasional weeds. Isolated patches of low-quality Diegan Coastal Sage Scrub vegetation are scattered on the property. Cumulatively, the isolated patches cover approximately 0.13 acres. The Diegan Coastal Sage Scrub would be removed as a result of the proposed development. Perthe biologisYs recommendation, the removal of this habitat would be mitigated at a 2:1 ratio. The mitigation could be accomplished through the recordation of an off-site Biological Conservation Easement of 0.26 acres of Coastal Sage Scrub habitat within the Mitigation Area, or the payment of an In-Lieu Fee at a rate established by the City. Currently, the fee is $10,000 per acre. The extension of the water main and sewer main across Poway Creek and Beeler Creek, respectively, would avoid impacting the creek and associated habitat through the use of construction techniques that would not require trenching. The existing water main would be upsized by using a pipe bursting technique, i.e., inserting a new collapsed pipe inside the existing pipe. The new pipe opens up inside the existing pipe, thereby busting the old pipe into small pieces. The force sewer main would be tunneled under the creek by using a directional boring technique. Archaeoloav-The site is located in an area with a high probability that an archaeological site is present according the City of Poway's General Plan. An archaeological report dated February 11, 2003, prepared by Brian Smith and Associates for the project site, did not identify any cultural resources within the project site of the proposed road and utility improvements. However, since the date of the report, the off-site sewer force main alignment has been changed to cross Beeler Creek. A Condition of Approval in the proposed Resolution requires that the report be expanded to include this off-site alignment and make a recommendation whether monitoring will be required for excavation for the sewer main. 7 of 64 July 5, 2005 Item # � Agenda Report July 5, 2005 Page 7 FISCAL IMPACT None. PUBLIC NOTIFICATION AND CORRESPONDENCE Public notice was published in the Poway News Chieftain and mailed to 33 property owners within 500 feet of the project site.

P- A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF POWAY, CALIFORNIA, APPROVING A MITIGATED NEGATIVE DECLARATION AND TENTATIVE TRACT MAP (TTM) 01-02 ASSESSOR'S PARCEL NUMBER 316-071-06 WHEREAS, a request for a Tentative Tract Map (TTM) 01-02 to subdivide a 5.6-acre property at 12664 Cobblestone Creek Road, within the Rural Residential C zone, into five (5) one-acre residential lots and a lettered lot to contain a public sewer pump station; and WHEREAS, the City Council has read and considered the Agenda Report for the proposed project and has considered other evidence presented at the public hearing; and WHEREAS, on July 5, 2005, the City Council held a public hearing on the above- referenced item. NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Poway as follows: Section 1: The City Council has considered the Environmental Initial Study (EIS), Mitigated Negative Declaration (MND), and associated Mitigation Monitoring Program shown as Exhibit A of this Resolution for TTM 01-02. The subject EIS and MND documentation are fully incorporated herein by this reference. The City Council finds, on the basis of the whole record before it, that there is no substantial evidence the project will have a significant impact on the environment, that the mitigation measures contained in the EIS and Exhibit A hereof will mitigate potentially significant impacts to a less than significant level, and that the MND reflects the independent judgment and analysis of the City. The City Council hereby approves the MND and the associated Mitigation Monitoring Program. Section 2: Pursuant to the City of Poway Habitat Conservation Plan (Poway HCP), a Biological Assessment and Tree Inventory Report were completed for the on-site and off-site improvements by Vincent N. Scheidt, Biological Consultant, as summarized in the biological report dated March 22, 2005, submitted for the project. The biological report concluded that the project would impact isolated patches of low-quality Diegan Coastal Sage Scrub vegetation that are scattered on the northern and southern portion of the property. Cumulatively, the isolated patches cover approximately 0.13 acres and would be mitigated at a 2:1 ratio. The mitigation would be accomplished through the recordation of an off-site Biological Conservation Easement of 0.26 acres of Coastal Sage Scrub habitat within the Mitigation Area, or the payment of an In-Lieu Fee at a rate established by the City. Currently, the fee is $10,000 per acre. In accordance with the 9 of 64 ATTACHMENT A July 5, 2005 Item # � Resolution No. P- Page 2 Poway HCP, the required findings for approval of the proposed mitigation for the removal of patches of habitat for TTM 01-02 are as follows: A. The mitigation is consistent with and furthers the implementing objectives of the Poway Habitat Conservation Plan in that the applicant will mitigate the removal of disturbed native vegetation at a 2:1 ratio through the recordation of an off-site Biological Conservation Easement within the Mitigation Area or the payment of an In-Lieu Fee at a rate established by the City. B. Off-site habitat mitigation or the cash in-lieu payment will go towards the purchase of mitigation habitat within the Mitigation Area and would enhance the long-term viability and function of the preserve system. C. The mitigation will be to the long-term benefit of the covered species and their habitats in that an off-site Biological Conservation Easement within the Mitigation Area would be recorded or a cash In-Lieu Fee will be paid to go towards the purchase of land that will have undisturbed habitat on which a Biological Conservation Easement will be recorded. Said land will promote a meaningful addition to the assembly of a viable regional system of interconnected natural habitat resources, habitat linkages, buffers, and wildlife corridors. D. The mitigation shall foster the incremental implementation of the Poway HCP in an effective and efficient manner in that any off-site conservation area is required to be within an identified Mitigation Area within the City. E. The mitigation will not result in a negative fiscal impact with regard to the successful implementation of the Poway Habitat Conservation Plan. Section 3: The findings, in accordance with the State Subdivision Map Act (Government Code Section 66410 et. seq.) for TTM 01-02, are made as follows: A. The Tentative Tract Map is consistent with the General Plan in that it proposes to create five residential lots at densities consistent with the General Plan. B. The design and improvements required of the Tentative Tract Map are consistent with the General Plan in that the approved lot sizes and configurations adhere to the development standards for the Rural Residential C zone. C. The site is physically suitable for the type of development and the density proposed in that the site is large enough to provide five residential lots, with dimensions that are in keeping with the General Plan and Zoning Ordinance standards. D. The design of the Tentative Tract Map is not likely to cause substantial environmental damage and avoidable injury to humans and wildlife or their 10 of 64 July 5, 2005 Item # � Resolution No. P- Page 3 habitat in that the removal of isolated patches of Costal Sage Scrub will be mitigated off-site within the Mitigation Area or the payment of an In-Lieu Fee. Impacts to wetlands habitat will be avoided by installing the water main using a pipe bursting technique and by installing the sewer main under the creek using a directional boring technique. E. The Tentative Tract Map is not likely to cause serious public health problems as existing City water mains will be upsized, and a new sewer service will be provided to the property to serve the new development and other homes in the neighborhood. F. The design of the Tentative Tract Map will not conflict with any easement by the public at large, now of record, for access through or use of the property within the proposed subdivision. Section 4: The findings in accordance with Government Code Section 66020 for the public improvements, are made as follows: A. The design and improvements of the proposed development are consistent with all elements of the Poway General Plan, as well as City Ordinances, because all necessary services and facilities will be available to serve the project. The construction of public improvements is needed as a result of the proposed development to protect the public health, safety, and welfare as identified below: 1. Public waterline and access easement(s) over, along and across the entire proposed private street from Poway Road to and including the subdivision. In addition, should the fire hydrants be located outside this area, an additional water line easement, a minimum of 20 feet wide shall also be dedicated. 2. A public trail and sewer easement, with access rights to both, shall be dedicated to the City. 3. An off-site sewer easement with access rights from Boulder View Road to the Subdivision shall be dedicated to the City. 4. Access easement to Lot "A", from the existing private street. 5. Lot "A" shall be dedicated in fee to the City for sewer pump station purposes. Section 5: The City Council hereby approves TTM 01-02, to allow the subdivision of 5.6 acres of land located at 12664 Cobblestone Creek Road, within the Rural Residential C zone, into five (5) one-acre residential lots and a lettered lot to contain a 11 of 64 July 5, 2005 Item # � Resolution No. P- Page 4 public sewer pump station as shown on the Tentative Tract Map, dated March 24, 2005, subject to the following conditions: A. This approval is not inclusive of the design of the proposed single-family homes. Separate approval of the home design and footprints shall be applied for through the Minor Development Review Application process covering individual lots or the Development Review process covering all five lots prior to issuance of Building Permits. B. Approval of this request shall not waive compliance with any sections of the Zoning Ordinance and all other applicable City Ordinances in effect at the time of Building Permit issuance. C. This approval is based on the existing site conditions represented on the approved Tentative Tract Map. If actual conditions vary from representations, the approved map must be changed to reflect the actual conditions. Any substantial changes to the approved Tentative Tract Map, prior to Tract Map approval, must be approved by the Director of Development Services and may require approval of the City Council. D. Pursuant to Section 66474.9 (b) of the State Government Code, the subdivider shall defend, indemnify, and hold harmless the local agency or its agents, officers, and employees from any claim, action or proceeding against the local agency or its agents, officers, or employees to attack, set aside, void, or annul, an approval of the local agency, advisory agency, appeal board, or legislative body concerning a subdivision, which action is brought within the time period provided in Section 66499.37 of the State Government Code. The City of Poway shall promptly notify the subdivider of any claim, action, or proceeding and the City shall cooperate fully in the defense. If the City fails to promptly notify the subdivider of any claim, action, or proceeding, or if the City fails to cooperate fully in the defense, the subdivider shall not thereafter be responsible to defend, indemnify, or hold harmless the City. E. The developer is required to comply with the Poway Noise Ordinance and Grading Ordinance requirements that govern construction activity and noise levels. (Engineering) F. Within 30 days of this approval, the applicant shall submit in writing that all Conditions of Approval have been read and understood. G. Within 30 days after City Council approval of the tentative map, the subdivider shall make a reservation for a sewer Letter of Availability for five Equivalent Dwelling Units (EDU) and pay the City a non-refundable sewer connection fee of 12 of 64 July 5, 2005 Item # � Resolution No. P- Page 5 $2,356. This amount represents twenty percent (20%) of the sewage connection fee. H. Within 30 days after City Council approval of the final map, the subdivider shall pay the City an additional 30% sewer connection fee of $3,534. The remaining balance of the sewer connection fee, in the amount of $5,890, shall be paid prior to Building Permit issuance, but no later than 36 months from recordation of the first Final Map, unless otherwise granted a time extension to complete the project. This amount represents a balance of $1,178.00 for each residential lot. Reference is hereby made to City Ordinance No. 83, codified as Chapter 13.08 of the Poway Municipal Code, as to time extensions and for other particulars. I. Prior to Final Map approval, unless other timing is indicated, the following conditions shall be complied with: (Engineering) 1. Submittal of the Final Map to the City for review and payment of map checking fee ($1000.00 per sheet).

A monumentation bond in an amount acceptable to the City Engineer shall be posted. (Planning) 10. Prior to Final Map, Grading Permit, Administrative Clearing Permit, or Improvement Plan approval whichever comes first: 14 of 64 July 5, 2005 Item # � Resolution No. P- Page 7 a. The archaeological report dated February 11, 2003, prepared by Brian Smith and Associates, shall be expanded to include the areas of the currently proposed sewer main location, not previously covered in the report. The update is required because the alignment is located within an area with a high probability that an archaeological site is present, according the City of Poway's General Plan. The report shall make a recommendation whether monitoring will be required for excavation of a section of the sewer main alignment. b.

INTRODUCTION This Environmental Initial Study and Checklist, along with information contained in the public record, comprise the environmental documentation for the proposed project as described below pursuant to the requirements of the California Environmental Quality Act (CEQA). Based upon the information contained herein and in the public record, the City of Poway has prepared a Negative Declaration for the proposed project. B. PROJECT INFORMATION 1. Project Title: Environmental Assessment and Tentative Tract Map 01-02 2. Lead Agency Name and Address: Citv of Powav 13325 Civic Center Drive Powav CA 92064 3. Contact Person and Phone Number: Oda Audish. (8581668-4661 4. Project Location: 12664 Cobblestone Creek Trail, at the terminus of Cobblestone Creek Trail: APN 316-071-06 (See Attachment A U S G S Map) Project Sponsor's Name and Address: Jeff Fisk. 931 West Center. Orem. UT 84057 6. General Plan Designation: Rural Residential C Zoning: Rural Residential C (RR-C) (1 2 4-acre minimum lot size) 7. Description of Project: (Describe the whole action involved, including, but not limited to, later phases of the project, and any secondary, support, or off-site features necessary for its implementation. Attach additional sheets if necessary). The �roiect is a aroposal to subdivide a 5 6-acre aropertv into five (51 one-acre residential lots and a lettered lot to contain a public sewer auma station (See Attachments A B and C). The lot size is consistent with the RR-C zone standards The site is located within an existinq rural residential area and the lots would be consistent in size and shaae with the surroundinq area. The 5 6-acre oroiect site is level and has been aartiallv develoaed An existina, 2,000-spuare-foot barn is located on the northeast corner of the �ropertv within the aroposed Lot 2 of the subdivision. The remaining site has been disturbed and contams horse corrals and ornamental olants exceot for isolated patches of low-aualitv Dieqan Coastal Saqe Scrub veqetation that are scattered on the northern and southern portion of the aropertv. Cumulativelv the isolated patches cover aaaroximatelv 0 13 acres. The northeast and southeast corners of the oroiect site are located within the 100-vear floodwav and floodolain of Beeler Creek. The creek channel and bank are located off-site 35 of 64 � July 5, 2005 Item # � _ _ __ EIS and Checklist Environmental Assessment and TTM 01-02 and existinq sinple-familv homes are located between the oroiect site and the creek channel. The site is accessed from Powav Road via two private streets Cobblestone Creek Road and Cobblestone Creek Trail. The road crosses Poway Creek via an existinq bridqe Cobblestone Creek Road would be widened to 20 feet south of the bridqe and would receive additional aavin4 and a slurry coat to reoair severelv damaged areas Cobblestone Creek Trail would be oaved to 20 feet in width and be arovided with a cul-de- sac at the southern terminus. An easement providinq access to a neiqhborinq proqertv to the east bisects the prooertv. This access easement would also be widened to 20 feet and imaroved with a fire-department turnaround The aroiect would result in the extension of water and sewer mains to the site These mains would need to cross Poway Creek or Beeler Creek as described below On Julv 10, 2001, the aoplicant and Citv staff met with the Deaartment of Fish and Game The Repional Water Qualitv Control Board. and the U S Fish and Wildlife Aqencv ("State and Federal Aaencies") to discuss how to brinq the mains across the creek The State and Federal Aqencies recommended that the creeks be crossed bv tunnelinq under the creeks via directional borina techniaue therebv minimizinq the ootential impacts to the creek and associated habitat. The pr000sal would �rovide sewer service to the aroiect site bv connectinq to an existinq sewer main within Boulder View Drive for a distance of approximatelv 2 000 feet Because the proiect site is located at a lower elevation than that of the existinq sewer main, the sewer would have to be pumped via a force main A sewer numo station is proposed to be constructed within the subdivision limits on a seqarate lot (Lot A) The force main would extend from the oroqosed sewer nump station to the southern limits of the proiect site, within the existinq Cobblestone Creek Trail aliqnment The main would then travel off-site in an easterlv direction along the boundarv of a dedicated open space propertv located to the south of the subdivision site under the creek and then within an existinq dirt service road. Imaacts to riparian habitat bv the creek would be avoided bv borinq under the creek and olacinq the force main in the "tunnel" The force main would then turn northeast cross a orivate developed qropertv and ultimatelv tie into the existing sewer main located within Boulder View Road A seoarate gravitv fed sewer main would be constructed from the intersection of Cobblestone Creek Road and Cobblestone Creek Trail to the aump station. A second qravitv sewer main would extend from the new Cobblestone Creek Trail cul-de-sac to the oump station Individual lots would feed into the gravitv feed sewer mains. The existinq water main. servinq the Cobblestone Creek neiqhborhood extends from Powav Road under Powav Creek to Cobblestone Creek Road at which point the main follows Cobblestone Creek Road and Cobblestone Creek Trail The diameter of this line would be increased irt size from its existing 4 to 6 inches to 8 inches to provide adeauate fire flow to the area. Imaacts to habitat would be avoided bv the use of aipe-burstinq techniaue as described in Section IV Bioloqical Resources A fire hvdrant would be installed within the oroiect area off of the new water main 36 of 64 2 July 5, 2005 Item # 7 EIS and Checklist Environmental Assessment and TTM 01-02 An existina utilitv qole would be removed and the existina and oroposed utility connections would be placed underqround up to the nearest existinq power qole to the east. A trail would be constructed and dedicated to the CiN from the cul de sac to connect to the existmp trail located withm the existinq open space lot located to the south of oroiect site. 8. Surrounding Land Uses and Setting: North: Sinqle-familv homes East: Sinple-familv homes South: Open Space owned bv the Citv of Powav West: Sinqle-familv homes 9.

I find that although the proposed project could have a significant effect on the environment, � there will not be a significant effect in this case as revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an � ENVIRONMENTAL IMPACT REPORT are required. I find that the proposed MAY have a "potentially significant impacY' or "potentially � significant unless mitigated" impact on the environment but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards; and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, � because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

DISCUSSION OF ENVIRONMENTAL EVALUATION Please refer to the Environmental Initial Study Checklist Form above when reading the following evafuation. I. AESTHETICS: On-Site The site is located at the terminus of an existing gravel road. The property contains a barn structure, horse corrals, ornamental plants and some patches of native vegetation as further described in Section IV, Biological Resources, of this document. The future development would be consistent with the surrounding residential development and would not affect any scenic vista or resources. Off-site The proposed off-site utility and road improvements,would occur near mature trees. A Tree Inventory Report was prepared by Vincent Scheidt, for the site and off-site utility and street improvements as discussed further in Section IV, Biological Resources. Based on the inventory and a site inspection with the City's arborist, it was determined that the proposed improvements would not result in the removal of trees, with the proper fine-tuning of the final alignment of the utility and street improvements and by the proper cutting of tree roots. II. AGRICULTURAL RESOURCES: There are no known slgnificant agricultural resources that would be impacted by this project. 50 of 64 16 July 5, 2005 Item # � ' �IS and Chedclist Environmental Assessment and TTM 01-02 III, AIR QUALITY: Assessment of Potential Lonq-Term Impact of the Proiect The pro�ect could ultimately result in the development of five (5) residential lots. Automobile use and other miscellaneous air emissions associated with each residence will have an incremental, potentially long-term impact on the ambient air quality in the area. A San Diego Regional Air Quality Strategies Plan-1994 Qointly developed by the Air Pollution Control District and the San Diego Association of Governments (SANDAG)) exists for the San Diego area and provides strategies for pollution controls to improve air quality in the region. Land use plans and build out projections of the General Plans of jurisdictions within the San Diego area were considered in establishing the strategies of the Regional Air Quality Strategies Pfan. The Poway General Plan includes strategies that are directed toward reducing air emissions through land use patterns, transportation planning, regional agency cooperation, energy conservation, and construction. The proposed 5-lot subdivision is consistent with the Poway General Plan. Therefore, the proposed project is also consistent with the San Diego Regional Air Quality Strategies Plan through the land use and growth assumptions that were used in the document. Such consistency insures that the pcoject will not have a significant adverse long-term impact on air quality in the area. Assessment of Potential Short-Term Im acts of the Pro'ect Grading on the site couid result in short-term impacts to the air quality of the area. The project will comply with the standards of the Poway Grading Ordinance, NPDES and SUSMP (Standard Urban Stormwater Mitigation Plan) which include the following: ■ After clearing, grading or earth moving, the project area shall be wet down su�ciently enough to prevent dust pick-up by the wind. ■ Street sweeping shall be implemented as required. IV. BIOLOGICAL RESOURCES: The site is not located within the Mitigation Area of the Poway Subarea Habitat Conservation Plan (Poway HCP). A barn structure is located on the northeast comer of the property. The remaining site has been disturbed and contains horse corrals and omamental plants. Beeler Creek is located to the east of the project site. The 100-year floodway extends into the subject property on the northeast and southeast corner of the property. The creek bed and banks are located off-site. A Biologicai Assessment and Tree Inventory Report were completed for the on-site and off-site improvements by Vincent N. Scheidt, Biological Consultant, as summarized in the biological �eport dated March 22, 2005. The report is based o 51 of 64 17 July 5, 2005 Item #� ' �EIS and Checklist Environmental Assessment and TTM 01-02 a field reconnaissance. The report concluded that 5.45 acres of the site is comprised primarily of a barn structure, ornamental plants, and occasional weeds. Isolated patches of low-quality Diegan Coastal Sage Scrub vegetation are scattered on the northern and southern portion of the property. Cumulatively the isolated patches cover approximately 0.13 acres. Only one sensitive plant, Graceful Tarplant, and one sensitive animal species, Westem Bluebird, were detected during the survey. None of these species are covered under the City's HCP. Because the parcel supports only small patches of native vegetation, which constitute habitat for at least two sensitive species, Graceful Tarplant and Westem Bluebird, the biologist report recommends an appropriate mitigation ratio as it applies to impacted areas, at 2:1. Floodwav. The 100-year floodway limits from Beeler Creek extend into the project area along the northeast (Proposed Lot 2) and southeast (Proposed Lot 5) corners as can be seen on Attachment B. It is the City's policy to provide a 50-foot setback from the limits of a 100-year floodway to protect a riparian corridor, unless site conditions justify a smaller setback. It should be noted that the biofogy report did not identify wetland or riparian habitat on-site, and an existing residence and accessory building are located within the floodway area between the project site and the actual creek bed to the east. The proposed Lot 2, located on the northeast corner of the project site has been previously disturbed and contains an approximately 2,000-square-foot barn structure built in 1989 and located approximately 30 feet from the floodway. The grading plans for the bam dated September 11, 1989, show that grading occurred up to the limits of the floodway. A concrete slab extending from the barn maintains a 20-foot setback from the floodway. A neighboring residence is located within the floodway, behnreen the project site and the creek channel. It is anticipated that the existing barn would be replaced by a single-family residence in the future. Given the existing development on-site and off-site, it would be appropriate to allow the footprint of a future residence on Lot 2 to maintain the 30-foot setback of the existing bam from the floodway and to allow for a walkway to be constructed around the residence within 24 feet of the flood-way. An Open Space Easement would be granted across the 24-foot buffer and its limits marked. The proposed Lot 5, located on the southeast corner of the project site, does not contain any structures but has been previously disturbed with horse corrals. A 50- foot open space buffer from the limits of the floodway on the proposed Lot 5 would be required. The buffer wouid be in the form of an Open Space Easement to be dedicated to the City of Poway. The open space lot would be marked. 52 of 64 July 5, 2005 Item #� 18 � EIS and Checklist Environmental Assessment and TTM 01-02 Off-site Imorovements On July 10, 2001, the applicant and City staff met with the Department of Fish and Game, The Regional Water Quality Control Board, and the U.S. Fish and Wildlife Agency ("Agencies") to discuss how to bring the mains across the creek. The Agencies recommended that the applicant use alternatives to trenching in order to minimize the potential impacts to the creek and associated habitat. The Agencies recommended tunneling under the creeks via the directional boring technique. Force Sewer Main Imorovements - The proposal includes providing sewer service to the project site by connecting to an existing sewer main within Boulder View Drive, at a distance of approximately 2,000 feet. Because the project site is located at a lower elevation than that of the existing sewer main, the sewer wouid have to be pumped via the proposed sewer pump station, to be constnicted within the subdivision limits, and a force main. The force main wouid extend from the proposed sewer pump station to the southern limits of the project site, within the existing Cobblestone Creek Trail alignment. The main would then travel off-site to the south of the subdivision site in an easterly direction for approximately 1,500 feet. The main would first travel along the boundary of an existing dedicated open space property. With the use of directional boring technique the main would be bored underneath Beeler Creek, to avoid any impacts to the creekbed and associated habitat. The entry and exit points are to be located at a minimum of 50 feet from the limits of the floodway or riparian habitat limits, whichever is greater. The force main would continue within an existing dirt service road to the southeast corner of a private property known as APN 317-200-18, at which point the force main would leave the dirt road, turn northeast and "travel" across the private, developed property along an exiting utility easement, and ultimately tie into the existing sewer main located within Boulder View Road. Gravitv Sewer Main Imorovements - A separate gravity fed sewer main would be constructed from the intersection of Cobbiestone Creek Road and Cobblestone Creek Trail to the pump station. A second gravity sewer main would extend from the new Cobblestone Creek Traii cul-de-sac to the pump station. Individual lots would feed into the gravity feed sewer mains. Some of the existing homes in the neighborhood may connect in the future to the sewer and abandon their existing septic systems. Water Main Imorovements — The existing 4 to 6-inch water main extends from Poway Road, under Poway Creek to Cobblestone Creek Road, and then continues on within the alignment of Cobblestone Creek Road and Cobblestone Creek Trail. This main would be repiaced by a new 8-inch water main by pipe bursting the existing main from Poway Road to Cobblestone Creek. Pipe bursting is a trenchless construction method used in the rehabilitation of underground infrastructure, with minimal disruption to traffic and environmentally sensitive or significant areas. Pipe bursting breaks out the existing pipe by use of radial forces from inside the existing pipe. The fragments are forced outward into the soil and a new pipe is pulled into the bore formed by the bursting device. The pipe bursting technique would eliminate the need to excavate within the creek area and therefo e 53 of 64 July 5, 2005 Item #� 19 ' �IS and Checklist Environmental Assessment and TTM 01-02 would not impact riparian or wetland habitat. The remainder of the new main would be located within the existing roadway. Road Imorovements - The widening of Cobblestone Creek Road and Cobblestone Creek Trail could impact one mature Coast Live Oak that is located along the shoulder of the existing road. Grading in this area must be avoided, and all material in proximity to this tree should be placed under the supervision of a registered arborist or qualified biologist, to ensure that the road widening does not adversely impair the roots and trunk of the tree. Tree Inventorv - A Tree Inventory Report was completed for the proposed subdivision and associated off-site road and utility improvements. Based on the current project description, there are approximately 151 trees within the project area. Of the 151 trees, approximately 36 trees are Coast Live Oak trees and 4 trees are native California Sycamores. Both tree species are native to the City of Poway per the City's Urban Forestry Ordinance and shall be protected as required by the Poway Municipal Code. The remaining trees consist primarily of Eucalyptus, Pine, and Palm trees. The proposed project does not anticipate the removal of any trees as a result of the proposed grading for the subdivision and off-site utilities. Based on a site visit with the City's arborist, Mitigation Measures listed below would avoid or minimize impacts to the trees. Mitiqation: Prior to Final Map approval, grading plan approval, improvement plan approval, or Administrative Clearing Permit, whichever is first, the following mitigation must be completed: a. The loss of 0.13 acres of Diegan Coastal Sage Scrub habitat shail be mitigated at a 2:1 ratio by paying into the City's In-Lieu Fee program for the future purchase of habitat land within the Mitigation Area of the Poway HCP with similar quality habitat.. � b. Obtain a 1600-series Streambed Alteration Agreement from California Department of Fish and Game for the boring activities as a contingency plan, should a "frac-ouY' (accidental release of drilling mud) occur boring beneath the riparian areas. Should a frac-out occur, the Calffornia Department of Fish and Game would be notified to assist with the containment of the damage to downstream habitats. The securement of this Agreement would be made a Specific Condition of project approval. c. Consult with the Regionai Water Quality Controf Board and obtain 401 Permit if required. d• Biological monitoring wouid be required during pit excavation, water pipe bursting, and boring for the installation of the sewer force main. The sewer main pipe shall be bored beneath the riparian area. All necessary Stormwater Pollution Prevention precautions, as recommended by a qualified biologfst, shall be in place due to the high sensitivity of the surrounding habitats. e. Biological monitoring would be required during pit excavation for the installation of the water main. The new water main pipe shall replace the 54 of 64 20 July 5, 2005 Item # � ' o�o miu t.r16GKll5i Environmental Assessment and TTM 01-02 existing water main by use of pipe bursting technique beneath the riparian area. f. A Tree Protection Plan shall be prepared by a qualified arborist and submitted to the City outlining measures as to how to protect trees during the construction of the utilities and grading. The measures shall include, but not be limited to, a review of the location of the utility main within the roadway to ensure minimum impacts to trees, trenching and root pruning techniques, and protective fencing around trees. g. Any trees required to be removed shall be subject to the Tree Removal Permit and tree replacement, to the satisfaction of the Director of Development Services, consistent with Chapter 12-32, Urban Forestry, of the City of Poway's Municipal Code. h. A qualified arborist or biologist shall monitor sewer and water main excavation and road widening activities to ensure that roots and trunks of trees are not adversely impacted. i. A 24-foot open space buffer from the limits of the floodway shall be established on the proposed Lot 2. The buffer would be in the form of an Open Space Easement to be dedicated to the Ciry of Poway. The Open Space lot would be marked. j. A 50-foot open space buffer from the limits of the floodway shall be established on the proposed Lot 5. The buffer would be in the form of an Open Space Easement to be dedicated to the City of Poway. The open space lot would be marked. V. CULTURAL RESOURCES: According to Figure VI-4 of the City of Poway's General Plan, the subject property is located in an area with a high probabiliry that an archaeological site is present. Brian Smith and Associates, Environmental Services, prepared a cultural resource survey of the site. Their report, dated March 1, 2001, stated that no artifacts, cultural features, or other evidence of archaeological sites were identified on the property. A survey check of records used for the Master Environmental Assessment completed for the City of Poway indicated that there are no previously recorded sites on the property. Based on these observations and research, the archaeologist concluded that the proposed development of this parcel would not impact cultural resources. No additional studies or monitoring are recommended. Brian Smith and Associates, Environmental Services, prepared a second archeological survey for off-site improvements, consisting of the widening of Cobblestone Creek and the installation of wate� and sewer mains from Poway Road to the project site. Their report, dated February 11, 2003, did not identify any cultural resources within the project area. However, evidence of archaeological materials was noted east and west of the Cobblestone Creek Road, between Poway Road and Poway Creek. A survey check of records used for the Master Environmental Assessment completed for the City of Poway indicated that one previously-recorded prehistoric site was present within the off- site corridor in the area immediately adjacent to and south of Poway Road, corresponding to the milling features and artifacts observed during the survey. 21 55 of 64 July 5, 2005 Item #� ' �IS and Checklist Environmental Assessment and TTM 01-02 The report recommended that "monitoring only" be conducted of excavations for utilities in the area befiveen Poway Road and Poway Creek. Since the February 11, 2003, report, the proposed location of the sewer and water mains have been modified. The utility lines will no longer extend from Poway Road through Cobblestone Creek Road across Poway Creek. instead, the water main will extend from Poway Road in the same alignment as the existing water line located south of Cobblestone Creek Road. The water main will be constructed under Poway Creek using pipe-bursting technique and will continue along the existing Cobblestone Creek Road already covered in the report. Therefore, the proposed water main construction would not affect cultural resources. The sewer force main location has also been changed to extend from the project site and extend within the existing Cobblestone Creek Trail to the south and then proceed east along the southern boundary of the subdivision project site. The force main then crosses under the creek and continues south within the limits of an existing dirt service road. The force main then turns north, thereby leaving the dirt road, and crosses a private developed property and ultimately ties into the existing sewer main located within Boulder View Road. Mitigation: Prior to approval of the Final Map, Improvement Plans, or Grading Permit, whichever comes first, the archaeological report dated February 11, 2003, prepared by Brian Smith and Associates shall be expanded to include the areas of the curcently proposed sewer main location, not previously covered in the report. The update is required because the alignment is located within an area with a high probability that an archaeologicai site is present according the City of Poway's General Plan. The report shall make a recommendation whether monitoring will be required for excavation of a section of the sewer main alignment. VI. GEOLOGY AND SOILS: The project will not have a significant adverse impact on the geology and soils in the area. A general assessment of the area was completed during the preparation of the Soils and Geology Sections of the Master Environmentai Assessment for the City of Poway, prepared in conjunction with the 1990 update to the Poway General Plan. According to Figure 2-1�of the Master Environmental Assessment, the subject property is in an area that consists of alluvium soil type. Development of the site will require compliance with the Poway Grading Ordinance. As part of the grading plan review process, a site-specific soils study wiil be provided prior to Grading Permit issuance. VII. HAZARDS AND HAZARDOUS MATERIALS: Pu�suant to Government Code Section 65962.5, the subject property is not listed on the current listing of the Hazardous Materials Establishments and Sites as prepared by the San Diego County Department of Environmental Health. The 22 56 of 64 July 5, 2005 Item #� ' �EIS and Checklist Environmental Assessment and TTM 01-02 subject property is vacant and undeveloped. No known illegal dumping or fuel storage tanks exist on the site. The project is a residential subdivision and the use will not involve hazardous materials. The project, therefore, will not result in a significant adverse hazardous impact in the area. VIII. HYDROLOGY AND WATER QUALITY: According to Flood Insurance Rate Map No. 06073C1354 F, published by the Federal Emergency Management Agency, the northeast corner is located within the 100-year floodway and floodplain of Beeler Creek (Proposed Lot 2). The southeast comer is also located within the 100-year floodway (Proposed Lot 5). The 5.6-acre project site is partially developed. The majority of the remaining site has been disturbed and contains non-native vegetation. An existing structure is located on the northeast corner of the property within the proposed Lot 2 outside the 100-year floodway or floodplain area. Based on the required floodway buffers discussed above in Section IV Biological Resources, no new structures would be located within the floodway or floodplain areas. An incremental increase in the amount of surface runoff will result from the construction of impervious surfaces when the subdivided residential lots are developed and the access roads are constructed. The developer is required to construct drainage improvements that are capable of handling run-off on the site and that are designed in conformance with the City of Poway drainage standards. The proposed development will not have a significant adverse impact on water or ground water quality or quantity, nor promote increased erosion because the project has incorporated current State Regionat Water Quality Control Board and City of Poway SUSMP and NPDES requirements into the design. The proposed project would be designed to treat and slowly release run-off from the existing development and the new impervious area before entering the ground water or the creek area consistent with SUSMP requirements. Erosion wntrol plans will be required in association with the project grading plans. As discussed above in Section IV Biological Resources, the proposed project includes the construction of a force sewer main under Beeler Creek using a directionai boring technique and a water main under Poway Creek using a pipe- bursting technique. With the use of these techniques, the potential for impacts to the creek bed, water quality, and riparian habitat would be minimized. Mitigation Measures: a. Obtain a 1600-series Streambed Alteration Agreement from California Department of Fish and Game for the boring activities as a contingency plan, should a "frac-out" (accidental release of drilling mud) occur boring beneath the riparian areas. Should a frac-out occur, the California Department of Fish and Game would be notified to assist with the containment of the damage to downstream habitats. The securement of this Agreement would be made a Specific Condition of project approval. 57 of 64 July 5, 2005 Item #� 23 � EIS and Checklist Environmental Assessment and TTM 01-02 b. Consult with the Regional Water Quality Control Board and obtain 401 Permit if required. c. Biological monitoring would be required during pit excavation, water pipe bursting, and boring for the installation of the sewer force main. The sewer main pipe shall be bored beneath the riparian area. All necessary Stormwater Pollution Prevention precautions, as recommended by a qualified biologist, shall be in place due to the high sensitivity of the surrounding habitats. d. Biological monitoring would be required during pit excavation for the installation of the water main. The new water main pipe shall replace the existing water main by use of pipe bursting technique beneath the riparian area. IX. LAND USE AND PLANNING: Tentative Tract Map 01-02 has been designed to conform to the General Plan. Future development of the created lots will be required to comply with applicable City development standards. The site is located within an existing rural residential area, and the development would be consistent with the surrounding area. The site is located at the terminus of an existing dirt road, which would be improved. A trail would be constructed from the cul-de-sac to connect to the existing trail located within the existing open space lot located to the south of project site. X. MINERAL RESOURCES: Pursuant to the Soils and Geology Sections of the City of Poway Master Environmental Assessment prepared in conjunction with the 1990 update to the Poway General Plan, there are no known mineral resources on the site. XI. NOISE: The project site is located approximately 800 feet from Poway Road. Therefore, it is not anticipated that the existing noise so�rces will exceed the above referenced noise limits. Therefore, will not have a significant adverse impact on the project. Development associated with the subdivision will result in a temporary increase in ambient noise levels in the area during the construction phases. The developer will be required to comply with the City's Noise Ordinance requirements that govern construction activity. XII. POPULATION AND HOUSING: The project will result in an incremental increase in area population; however, it is not considered to be significant in that the project is consistent with the Poway General Plan and the build-out density set forth in the document. 58 of 64 July 5, 2005 Item # �1 24 ' 'EIS and Checklist ' Environmental Assessment and TTM 01-02 XII. PUBLIC SERVICES: The project will improve the public services of the area. The proposed project would require the installation of a fire hydrant. The existing main would be upsized to 8 inch and extended to the project site to provide required fire flow to the new fire hydrant. The existing Cobblestone Creek Road and Cobblestone Creek Trail would be widened to 20 feet to meet fire department access requirements. The two street ends would provide fire apparatus turn-around. There are adequate public services to serve the project. XIII. RECREATION: The project will not have a significant adverse impact on recreational facilities in the area. There are adequate recreational facifities to serve the development and would add a trail li�kage. The proposed plans call for a trail linkage to be provided from the Cobblestone Creek Trail cul-de-sac to the open space lot to the south, in the form of an easement and trail improvements, to the satisfaction of the Director of Development Services. The trail would be a link in providing the Cobblestone Creek neighborhood access to the City's existing traii system off of Pomerado Road. XIV. TRANSPORTATION AND TRAFFIC: The project will not have a significant adverse impact on the level of service on area roadways. The project will result in an incremental increase in traffic in the area. According to the 1998 SANDAG Brief Guide of Traffic Generation Rates, a total of approximately 60 (12 average daily trips per lot [5 lots]) new daily vehicle trips will be generated by the project at build-out. Development of the property will require payment of Traffic Mitigation fees for each new residence. The project site is located at the terminus of Cobbiestone Creek Trail, a private road that connects to Poway Road. The width of the existing road varies. The roads leading to the site are in disrepair, due to the lack of maintenance and severe rains during the past winter. The proposed subdivision would install new water and sewer mains within sections of the road. in conjunction with widening the roads to 20 feet of asphalt, the road would receive a slurry seal and additional paving to fix pothofe areas or other similar situations where the road has deteriorated, to the satisfaction of the Director of Development Services, thereby giving the road a uniform appearance. The appiicant would be responsible for fixing any new damage to the road that has occurred as a result of the construction activities. The applicant would be required to establish a separate or join an existing road maintenance agreement for the future maintenance of the road. XV. UTILITIES AND SERVICE SYSTEMS: The project will not have a significant adverse impact on utility service in the area, in that water service and sewer mains will be e�ended to the site. The existing water main serving the Cobblestone Creek neighborhood extends from Poway Road across Poway Creek to Cobblestone Creek Road at which point it follows, �L 59 of 64 25 July 5, 2005 Item # �f ' EIS and Checklist Environmental Assessment and TTM 01-02 the road. This line would be increased in size from 6 inches to 8 inches to provide adequate fire flow to the area. A fire hydrant would be installed within the project area off of the new water main. The Cobblestone Creek neighborhood is served by private septic systems on each lot. Due to the proximity of the proposed subdivision to the creek, the project site would not be permitted to have a septic system. The proposal includes providing sewer service to the project site by connecting to an existing sewer main within Boulder View Drive, at a distance of approximately 2,000 feet. Because the project site is located at a lower elevation than the existing sewer main, the sewer would have to be pumped via a force main that originates at a sewer pump station, proposed to be located on a separate lot (Lot A) within the subdivision limits. Lot A would be dedicated to the City of Poway in fee. The force main would extend from the proposed sewer pump station to the southern limits of the project site within the existing Cobblesfone Creek Trail and then the main would travel off-site in an easterly direction along the boundary of an open space property dedicated to the City, under the creek and then along an existing dirt service road. The force main would then turn northeast, cross a private, developed property, and ultimately tie into the existing sewer main located within Boulder View Road. A separate gravity fed sewer main would be constructed from the intersection of Cobblestone Creek Road and Cobblestone Creek Trail to the pump station. A second gravity sewer main would extend from the new Cobblestone Creek Trail cul-de-sac to the pump station. An existing utility pole would be �emoved and the existing and proposed utilities would be placed underground up to the nearest existing power pole to the east. XVI. MANDATORY FINDING OF SIGNIFICANCE: TTM 01-02 will not have a significant adverse impact on the environment because of the design of the project, coupled with the mitigation measures identified in the previous sections in the areas described above, that wili be incorporated into the project design.

The reporting or monitoring program shall be designated to ensure compliance during project implementation." This mitigation monitoring program has been prepared in accordance with Section 21081.6 of the Public Resources Code. Non-compliance with any of these conditions, as identified by City staff or a designated monitor, shall result in issuance of a cease and desist order for all construction activities. The order shall remain in effect until compliance is assured. Non-compliance situations, which may occur subsequent to project construction, will be addressed on a case-by-case basis and may be subject to penalties according to the City of Poway Municipal Code.
