EXECUTIVE SUMMARY: Condition of Approval No. _ 107 for the Jordan Ranch subdivision (Tract 8024) requires that the Jordan Ranch development be annexed to the Fallon Village GHAD prior to filing of the first final map for the project. To satisfy this requirement, the developer of the Jordan Ranch project has petitioned the GHAD Board to annex the Jordan Ranch subdivision into the existing Fallon Village GHAD. The territory to be annexed pursuant to the Petition for Annexation is currently owned by the developer. The boundaries of the territory to be annexed and the boundaries of the Jordan Ranch subdivision are the same. In connection with the proposed annexation, a Jordan Ranch Development Annexation Plan of Control has been prepared. The proposed Plan of Control describes the work contemplated for the Jordan Ranch subdivision, including maintenance and monitoring activities, including slopes, debris benches, maintenance roads, trails, fencing, concrete lined drainage ditches, subdrains, subdrain outlets, retaining walls, storm drain improvements, and the water quality basin. If adopted, the Jordan Ranch Development Annexation Plan of Control would address geologic hazards within the Jordan Ranch subdivision. , FINANCIAL IMPACT: There is no immediate fiscal impact. Once the territory is annexed to the Fallon Village Geologic Hazard Abatement District and a funding mechanism has been approved by the Board of Directors and affected property owners, the costs associated with the operation of the Fallon Village GHAD will be offset by assessments paid by property owners within the District. The proposed assessments are supported by a detailed Engineer's Report prepared by a registered professional engineer certified by the State of California, and will be considered at a subsequent date in accordance with Proposition 218. RECOMMENDATION: Staff recommends that the Board of Directors (1) Receive Staff presentation; (2) Open the Public Hearing and receive comments from the public; (3) Close the Public Hearing and Page 1 of 3 ITEM NO. deliberate; and (4) Adopt the Resolution Ordering the Annexation of the Jordan Ranch Development (Tract 8024) into the Fallon Village Geologic Hazard Abatement District and Approving nd Adopting the Plan of Control. Submitted By eview d y Approv y Interim District Manager Assistant Cit~anager City Manager DESCRIPTION: On December 4, 2007, the Dublin City Council formed the Fallon Village Geologic ,Hazard Abatement District ("the District"). The members of the City Council serve as the Board of Directors of the District. On April 5, 2011 the Fallon Village GHAD Board of Directors adopted Resolution 1-11 accepting the Petition for Annexation to annex the Jordan Ranch property to the Fallon Village GRAD. The petition was executed by the owner of 100 percent of the property proposed to be annexed to the Fallon Village GHAD. The Board of Directors adopted a resolution setting a public hearing and noticing by mail the owner of real property to be annexed to the Fallon Village GRAD at least twenty (20) days before the May 3, 2011 hearing date. At the public hearing, if the owners of more than 50 percent of the assessed valuation of property within the territory to be annexed do not object to the annexation the Fallon Village GHAD Board of Directors may decide whether or not to approve the annexation of the Jordan Ranch development to the Fallon Village GHAD. If the GHAD Board of Directors wishes to approve the annexation of the Jordan Ranch development, the GHAD Board of Directors must adopt a resolution ordering the annexation. Public Resources Code section 26581 provides that any annexation ordered by the GHAD Board of Directors must also be approved by the legislative body which ordered the formation of the district, which in this case is the Dublin City Council. If the Board of Directors adopts the Resolution ordering the annexation of the Jordan Ranch Development, the City Council will be asked to adopt a resolution approving the annexation. The GHAD Board of Directors must in future actions take additional steps to assess territory within the Jordan Ranch annexation area. The Board of Directors must pass a budget and levy an assessment. Levying the assessment requires two steps: (a) approval of the engineer's report and the initiation of the assessment ballot proceeding, and (b) following the 45-day notice period required by Proposition 218, a public hearing to tabulate the assessment ballots and approve or deny the assessment. NOTICING REQUIREMENTS/PUBLIC OUTREACH: Notice of this hearing and a copy of the Staff Report were provided to Mission Valley Properties, owner of the Jordan Ranch Development, at least twenty days before this hearing.

To satisfy this requirement, the developer of the Jordan Ranch Development has petitioned the Board of Directors of the Fallon Village GHAD to annex the Jordan Ranch development into the existing Fallon Village GHAD ("GHAD" or "District"). • 1.1 PROPERTY IDENTIFICATION, OWNERSHIP AND MAINTENANCE • RESPONSIBILITIES A written description of the properties to be annexed into the existing Fallon Village GRAD is provided in Exhibit A and shown graphically on Exhibit B. The GHAD annexation area includes • Assessor's Parcel Numbers 985-27-7-4 and 9$5-27-6-4. Ownership and maintenance responsibilities for the individual parcels within the annexation area (Tract 8024) are shown on Figure 1. ~ 2.0 JORDAN RANCH PLAN OF CONTROL 2.1 GEOLOGIC HAZARDS Geologic hazards identified for the site in the Berlogar Geotechnical Consultants (BGC) • Geotechnical Investigation report (Reference 1) dated July 13, 2009, include the following items. • Slope instability ~ • Seismically induced ground shaking • Expansive soils These geologic hazards are not expected to be eliminated entirely by site grading. Slope instability or potential slope instability is not unique to this project, but is of importance for hillside projects throughout the San Francisco Bay Area, such as Fallon Village. Future stability • depends on various factors, including any introduction of natural or artificial groundwater, future • grading and earthquake ground shaking. 2.1.1 Slope Instability -Jordan Ranch • While no landslides were mapped on the site, areas of slope instability or landsliding will likely be identified during the life of the development. While we anticipate that most of the landsliding that may occur would involve the movement of shallow materials; the possibility of deeper future landsliding exists. • -1- ~GEC~ INCORPORATE D • • I ~5I ~ ~82a.ooo.oao Mission Valley Properties Jordan Ranch -Tract 8024 February 11, 2011 • A landslide is defined as a mass of rock, soil and other debris that has been displaced downslope • by sliding, flowing or falling. Landslides include cohesive block glides and disrupted slumps that have formed by displacement along a planar slip surface or rotation (displacement along a curved slip surface). Undercutting and erosion of hillside slopes can trigger slope failures. • Slope failures are also triggered by increased pore water pressure due to the infiltration of rainwater. The resulting decrease of shear resistance (internal resistance to deformation by shearing) can cause the slope to move. The level of the groundwater table varies with the amount of rainfall for the area. If rainfall is higher than average during the winter season, the water table • may be higher than average on a hillslope and groundwater pressures may become high. Under • these conditions, hillside movement can be activated. Areas of thickened soil cover on the hillslopes are known as colluvium (Qc). Colluvial deposits are typically the result of soil creep and may be in a weak, unconsolidated state, making them • susceptible to landsliding if undercut. colluvium is up to about 12 feet in thickness. Colluvial deposits located within open-space areas are natural landforms that do not require mitigation, except where they affect man-made improvements. Potential mitigation and repair measures for District areas near improvements are discussed in Section 3. 2.1.2 Seismically Induced Ground Shaking As identified in the geotechnical report, an earthquake of moderate to high magnitude generated • within the San Francisco Bay Region could cause considerable ground shaking at the site, similar • to that which has occurred in the past. Seismic slope stability has been considered in the geotechnical reports completed for the site; however, seismically generated slope failures could occur outside the grading limits within the Jordan Ranch Development. • 2.1.3 Expansive Soils Near-surface soils, in addition to claystone and siltstone at the site, could exhibit a very high potential for expansion. These potentially expansive soils could impact the planned site • development. Expansive soils shrink and swell as a result of moisture change. This can cause heaving and cracking of slabs-on-grade, pavements and structures founded on shallow foundations. The potential for expansive soils has been identified in previous reports for the property. Shrink and swell of expansive soils on slopes is a portion of the mechanism of creep • movement, which can result in shallow slope instability. 2.2 SLOPE STABILITY CONSIDERATIONS DURING MASS GRADING As recommended in the Geotechnical Investigation and Geotechnical Recommendations reports completed by BGC (Reference 1) and ENGEO dated August 17, 2010 (Reference 2) for the Jordan Ranch development, existing non-documented artificial fills within the graded area will be removed prior to engineered fill placement. In addition, unsuitable materials, which could ~ include colluvium and other unsuitable material will be overexcavated to firm undisturbed • _2_ EO G INCORPORATE D • • ~~~5i • Mission Vailey Properties 7828.000.000 Jorclaf7 Ranch -Tract 8024 February 11, 2011 • materials below the unsuitable material as determined by the project Geotechnical Engineer or Engineering Geologist (ENGEO} at the time of grading. Subdrains will be installed to collect subsurface waters. The configuration of the subdrainage system will be tailored to the subsurface i conditions at the time of grading. The planned location and elevation of subdrains and outlets are S shown on the Geotechnical Corrective Grading Plan (Figures 2 through 5). Each subexcavation • area will be reconstructed to final grade by keying and benching below the landslide plane with compacted, drained engineered fill. The cuts will be viewed by a geologist during grading to provide mitigation schemes for • unsuspected slope conditions, which could decrease the slope stability. Such conditions include unfavorable bedrock attitudes and seepage conditions. Grading reports shall be made available to the GHAD for its use following completion of the project development. • 2.3 GHAD-MAINTAINED IMPROVEMENTS AND OPEN SPACE AREAS The District will have authority and responsibility to manage erosion and other geologic hazards within the boundary shown in Exhibit B subject to the exclusions listed in Section 2.5 -Criteria • for GHAD Responsibility. The GHAD shall be responsible for monitoring and maintenance of • the following site improvements located within the GHAD-owned parcels that include Parcels A, K, S, and T, as shown on the Open Space Ownership and Maintenance Responsibilities Plan (Figure 1). • Slopes • • Debris benches • Maintenance roads • Developed trails including footbridge • Fencing • Concrete-lined drainage ditches • • Storm drain system improvements • Retaining walls ~ • Subdrains and subdrain outlets • Water quality basin • The central open space slopes within Parcels A and S are bisected by a drainage channel. Improvements planned within the limits of Parcel A include a water quality basin and wetlands. A developed trail is planned around the perimeter of Parcel S. In addition, a connector trail will bisect Parcel S and include a footbridge across the drainage channel. As shown on Figure 1, the central open space area will have two activity zones. In general, the Active Zone includes areas • around the perimeter of each parcel that will allow maintenance of the trail, water quality basin and vegetation management in the Fire Buffer Zone. The Intermittent Activity Zone includes the core area of Parcels A and S where the GRAD will not have scheduled maintenance activities, but will mitigate landslides, erosion, or the threat thereof, as they occur. While activity zones are . shown on Figure 1, this does not imply that GHAD Parcels A, S, or other GHAD-owned parcels ~ -3- ~ GO • INCORPORATE D • • I ~ • ~~5 • Mission Valley Properties 7$2$.000.000 Jordan Ranch -Tract $024 February 11, 2011 • within the Jordan Ranch are subject to interim or ongoing regulatory monitoring or remediation activities. The activity zones are provided to show where the GRAD anticipates different levels of activity within these parcels. As planned, the GRAD-owned parcels within the development would not be included within a conservation easement. As with the remainder of the • GHAD-maintained areas, the GHAD will be subject to State and Federal permit requirements • within Parcels A and S during mitigation activities. The GHAD intends to mitigate, prevent, abate or repair landslide or erosion hazards that could directly affect property within the GHAD boundary, as necessary to implement this Plan of • Control. The GHAD will also assume open-space management responsibilities that are required • for the Jordan Ranch project. These responsibilities will include vegetation management, erosion control, vegetation removal (fire suppression), and selected other maintenance associated with open space. • 2.3.1 General Landslide Mitigation The techniques the District may employ to prevent, mitigate or abate landsliding or adverse • erosion damage might include, but are not necessarily limited to: • Removal of the unstable earth mass. • Stabilization (either partial or total) of the landslide by removal and replacement with compacted drained fill. • Construction of structures to retain or divert landslide material or sediment. • Construction oferosion-control devices such as gabions, rip rap, geotextiles or lined ditches. S • Placement of drained engineered buttress fill. r • Placement of subsurface drainage devices (e.g., underdrains, or horizontal drains). • • Slope correction (e.g., gradient change, biotechnical stabilization, and slope trimming or . contouring). • Construction of additional surface ditches and/or detention basins, silt fences, sediment traps, or backfill or erosion channels. Potential landslide and erosion hazards can often best be mitigated by controlling soil saturation and water runoff and by maintaining the surface and subsurface drainage system. Maintenance shall be provided for lined surface drainage ditches and drainage terraces. r - 4 - • • I N C O R P O R A T E D • • • I~ 51 ~ ~a28.oo0.000 • Mission Valley Properties Jordan Ranch -Tract 8024 February 11, 2011 • • • 2.4 BIOTECHNICAL RECOMMENDATIONS FOR PREVENTION AND • MITIGATION OF EXISTING OR POTENTIAL EROSION HAZARDS Fill slopes within the boundaries of the District are expected to be erodible as will cut slopes in bedrock; therefore, the maintenance of vegetative cover is especially important. Vegetation • provides a protection on soil and exposed rock. It absorbs the impact of raindrops, reduces the velocity of runoff and retards erosion. • In many instances, adequate erosion protection for slopes can be accomplished with carefully • selected and placed biological elements (plants) without the use of structures (e.g., brush layering • and willow waddling). • In other areas, biotechnical slope protection may involve the use of mechanical elements or • structures in combination with biological elements to provide erosion control and help prevent small-scale slope failures. Locally, walls, welded-wire walls, gabion walls, rock walls, riprap and reinforced earth walls used in combination with carefully selected and planted vegetation can provide high-quality slope protection. The vegetation may be planted on the slope above a low • retaining structure or toe wall, or the interstices of the structure can be planted. 2.5 CRITERIA FOR GRAD RESPONSIBILITY • To establish an appropriate GRAD assessment level for the Jordan Ranch portion of the Fallon • Village GHAD, it is important to define clearly the limits of the GHAD's responsibilities. The GHAD will accept responsibility for property as described in Exhibit A. However, the intent of • this Plan of Control is not to extend the GHAD's responsibilities to every potential situation of • slope instability; as such, the following are exclusions from GRAD responsibility. • 2.5.1 Isolated or Remote Slope Instability • • The GHAD shall not have responsibility to monitor, abate, mitigate or control slope instability • that does not involve damage to, or pose a significant threat to damage, site improvements or • flood control capacity. As used herein, the term "site improvements" means buildings, roads, sidewalks, utilities, retaining walls, improved trails, swimming pools, geologic stabilization • features and drainage features or similar improvements. • • 2.5.2 Single Property The GHAD will not prevent, mitigate, abate or control geologic hazards which are limited in area to a single residential parcel of property unless the geologic hazard has damaged, or poses a • significant threat of damage to site improvements located on other property within the GHAD • boundaries. • • • _5_ EO G • I N C O R P O R A T E D • • ~~5i • • Mission Valley Properties 7828.000.000 Jordan Ranch -Tract 8024 February 11, 2011 • 2.5.3 Geologic Hazards Resulting From Negligence of Property Owner The GRAD may, in the general manager's sole discretion, decline to prevent, mitigate, abate or control geologic hazards which occur or result from any negligence of the homeowner and/or the • homeowner's contractors, agents or employees in developing, investigating, grading, • constructing, maintaining or performing or not performing any post-development work on the subject property. 2.5.4 Property Not Accepted The GRAD shall not have responsibility to repair damage which is situated on a parcel of real property, which the GHAD has not accepted in accordance with Exhibit E. The GHAD, however, may monitor, abate, mitigate or control slope instability on a parcel of real property • which the GHAD has not accepted in accordance with Exhibit E, provided that the GHAD • responsibility on such parcel shall be limited to the extent necessary to address damage or a significant threat to damage site improvements on aGHAD-accepted parcel. • 2.5.5 Geologic Hazard Which Requires Expenditure in Amount Exceeding the Value of • the Threatened or Damaged Improvement The GHAD may elect not to prevent, mitigate, abate or control a geologic hazard where, in the general manager's sole discretion, the anticipated expenditure required to be funded by the GHAD to prevent, mitigate, abate or control the geologic hazard will exceed the value of the • structure(s) and site improvement(s) threatened with damage or loss. 2.5.6 GHAD Funding or Reimbursement for Damaged or Destroyed Structures or Site • Improvements In the event a residence or any other private structure, site improvement or landscape feature is damaged or destroyed as a result of a geologic hazard, the District may fund or reimburse the ~ property owner for the expenses necessary to repair or replace the damaged or destroyed • structure, site improvement or landscaping. Unless otherwise authorized by the Board of Directors, the total dollar amount of the District funding or reimbursement paid to all property owners whose property is damaged by a geologic hazard may not exceed ten percent (10%) of the total costs incurred by the District in actually mitigating, abating or controlling the geologic • hazard that causes the damages. In the event the geologic hazard damages or destroys a structure, • site improvement or landscaping which violates any provisions of the City Building Code or City Code at the time of its installation or improvement, the District may decline to provide any funding, or reimbursement to the property owner for repair or replacement of the damaged • structure, improvement or landscaping. ~ For example, if a landslide causes $10,000 in structural damage to each one of four neighboring homes for a total of $40,000 in structural damage and it costs the District $100,000 to design and install a new retaining wall to abate the slide, the District may only reimburse each property owner $2,500 of their $10,000 in structural damage. -6- • INCORPORATE D • ~ ~I~b 51 • • Mission Valley Properties 7828.000.000 Jordan Ranch -Tract 8024 February 11, 2011 2.5.7 No Reimbursement of Expenses Incurred by Property Owners The GRAD will not be obligated to reimburse a property owner for expenses incurred for the prevention, mitigation, abatement, or control of a geologic hazard absent a written agreement • between the property owner and the GRAD to that effect, which agreement has been executed • prior to the property owner incurring said expenses, and following an investigation conducted by the GRAD. 2.6 PRIORITY FOR DISTRICT-FUNDED REPAIRS Emergency response and scheduled repair expenditures are to be prioritized by the General Manager, utilizing its discretion, based upon available funds, a prudent reserve and the approved operating budget. ~ Should available funds not be sufficient to undertake all of the identified remedial and preventive stabilization measures, the expenditures shall be prioritized as follows in descending order of priority: • A. The prevention, mitigation, abatement or control of geologic hazards that have either damaged or pose a significant threat of damage to residences, critical underground utilities or paved streets. • B. The prevention, mitigation, abatement or control of geologic hazards that have either ~ damaged or pose a significant threat of damage to private recreation facilities (e.g., pools, spas, etc.). • C. The prevention, mitigation, abatement or control of geologic hazards that have either • damaged or pose a significant threat of damage limited to loss of landscaping or other similar non-essential amenities. D. The prevention, mitigation, abatement or control of geologic hazards existing entirely on • open-space property and which have neither damaged nor pose a significant threat of damage to any site improvements. 2.7 MAINTENANCE AND MONITORING SCI3EDULE Geologic features and District-maintained facilities should be inspected on a regular basis. Budget permitting, inspections should generally be scheduled to occur two times per year in normal years and three or more times per year in years of heavy rainfall. The inspections should be scheduled to take place in the fall, prior to the first significant rainfall; mid-winter as • necessary during heavy rainfall years; and in spring at the end of the rainy season. It is anticipated that the monitoring events for the Jordan Ranch development and the Fallon Village development within the Fallon Village GRAD would be completed on the same schedule. -7- ~~Ea • INCORPORATE D • • ~~51 • Missioa~ Valley Properties 7828.000.000 Jordan Ranch -Tract 8024 February 11, 2011 • • A District Engineer and/or Geologist should inspect the lined surface of concrete-lined • drainage ditches within the District boundaries on a regular schedule. Repairs and maintenance should be performed as needed. Excess silt or sediment in ditches should be removed and cracked or broken ditches should be patched or repaired as required before the beginning of the next rainy season. • Several types of debris catchment structures are planned. Repairs and maintenance should be performed on a regular schedule. Excess debris should be removed to allow the structures to i maintain adequate catchment area. • • Subsurface drain outlets and horizontal drain outlets, if any, should be inspected on a regular schedule. Water flowing from these outlets should be measured and recorded during each inspection. Any suspicious interruption in flow should signal a need to unplug or clean by flushing the affected drain. • If installed, piezometers used to measure groundwater levels, or other instruments such as inclinometers and tiltmeters, should be monitored on a regular schedule. • Settlement-monitoring devices, if any, should be monitored on a regular schedule. In the • event of anomalous readings or excessive settlement, the monitoring frequency should be increased. • Inlets, outfalls or trash racks, if used, must be kept free of debris, and spillways must be • maintained. Attention should be given to plantings or other obstructions, which may interfere • with access by power equipment. • The water-quality basin facilities should be monitored and maintained in accordance with the Operations and Maintenance Manual for Water Quality Basin at Jordan Ranch. The District should review its inspection schedule annually and assess the effectiveness of its ~ preventive maintenance program on a regular basis. District staff should prepare an annual report to the Board of Directors with recommendations for maintenance and/or repair projects. • Consultants, as necessary, may be retained to undertake the needed studies. The District • Engineer and/or Engineering Geologist retained by the District shall prepare an annual inspection report for presentation to the District Board of Directors. ~ 3.0 GLOSSARY Engineer's Report -The document that establishes the individual property owners' GHAD assessment based on the projected expenses (budget) of the GHAD. • -8- ~~~0 • INCORPORATE D • ~ a3 • ~5~ ~ ~82~.ooo.oao • Mission Valley Properties Jordan Ranch -Tract 8024 February 11, 2011 i • Geological Hazard Abatement District (GHAD) Manager - An entity employing a licensed • Geotechnical Engineer who will oversee the operations of the GRAD including preparation of GHAD budgets.

Included within the District • were 1,043 single-family residences and adjacent open spaces within the Fallon Village development (Subdivision 7586). The Dublin City Council members act as the Board of Directors of the Fallon Village GHAD. Section 26509 of the Public Resources Code requires a Plan of Control, prepared by a State-Certified Engineering Geologist, as a prerequisite to formation of a GHAD. An Engineering Geologist, certified pursuant to Section 7822 of the Business and Professions Code, prepared the original Plan of Control for the Fallon Village GHAD. The Business and • Professions Code requires a Plan of Control to describe in detail geologic hazards, their location, • who is affected by them, and most significantly, a plan for the prevention, mitigation, abatement, or control thereof. In accordance with the requirements of the Public Resources Code, a proposed amendment to the original Fallon Village GHAD Plan of Control is to accompany the petition to annex the Jordan Ranch Property into the Fallon Village GRAD. BACKGROUND ~ A geotechnical investigation for the site dated July 13, 2009, was published by Berlogar • Geotechnical Consultants (BGC). The BGC report (Reference 1) summarizes a series of • geotechnical investigations performed between 1998 and 2005, consisting of solid flight, hollow stem, continuous core and hand auger borings and test pits. The BGC report also contains the boring logs from an environmental subsurface investigation by Northgate Environmental • Management in 2005. The locations of these explorations are depicted on the attached • Geotechnical Corrective Grading Plans (Figures 2 through 5). PROPOSED DEVELOPMENT • The a roved Vestin Tentative Ma for the ro ect was re ared b Ru eri-Jensen-Azar • pp g p p j P P Y gg (RJA) and is dated June 23, 2010. The overall 185-acre site will consist of two neighborhood development phases. The initial 66-acre Phase 1 development area will consist of approximately 252 single-family residential lots, streets, and a neighborhood park. These developments will be • located on the northern half of the site. Grading is expected to involve sheet fills approximately • 40 feet thick, and cuts up to 60 feet deep. Cut slopes are shown as high as 70 feet, and fill slopes up to about 25 feet in vertical high are planned. • Development of Phase II will involve approximately 528 single- and multi-family residential • units, streets, a school site, a community park, a water quality basin, and commercial development. As planned, there will be a total of 780 residential units.

Regional geologic maps were reviewed as part of the • Geotechnical Exploration and Recommendations Reports for the Jordan Ranch site. Along with • others, regional geologic maps of the area have been prepared recently by Graymer (1994). The regional mapping prepared by Graymer indicates that the site is underlain Tassajara/Green Valley formation. Regional mapping shows that bedrock units are generally trending in a northwest-southeast direction, are gently to moderately dipping in the southern portion of the • site, and are moderately to steeply dipping in the northeastern portion of the site. The dip of the bedrock is variable on the site with the predominant direction to the south. SITE GEOLOGY v The geologic units mapped on the site include bedrock and surficial deposits consisting of fill, alluvium and colluvium. The geologic units described below are adapted from a geotechnical investigation report completed by BGC for the site in 2009. • In general, alluvial and colluvial deposits are located on the lower-lying areas of the site. Undocumented artificial fill overlies the alluvium and colluvium in some locally disturbed areas. On the higher portions of the site, the colluvium tends to be a thinner mantle on the bedrock materials. GEOLOGIC UNITS Existing. Fill. Artificial fill was identified on the area of the western ranch buildings and for the • stock pond embankments. It appears that the fill encountered was derived from onsite excavation • during the construction of the cut portions of the existing building pad or minor site grading. Alluvium. Alluvium underlies the wider portions of valley floors on the subject property. Alluvial soils in the site vicinity typically consist of very stiff silty clay with minor amounts of • interbedded gravelly clay. On the southwest portion of the property, alluvium may be as much as 28 feet in depth. colluvium. The Quaternary colluvial deposits mapped across the site consist of a clay to silty • clay with rock fragments derived from the weathering of onsite materials. The colluvial materials range from a few to 12 feet in thickness. This material generally is moderately to highly expansive. Where colluvium is located on sloping ground, it maybe characteristically unstable. • Bedrock. Bedrock was encountered from 0 to 28 feet below the existing ground surface. The • bedrock encountered included sandstone, siltstone and claystone. The bedrock was weak to moderately strong, moderately to highly weathered and closely fractured. In general, bedding trends to the northwest and dips to the south. , ~ o INCORPORATE D • • ~ • • Mission Valley Properties 7828.000.000 • ,Jordan Ranch -Tract 8024 February 11, 2011 • GROUNDWATER During the site explorations conducted between 1998 and 2005, groundwater was encountered in several exploratory soil borings and test pits. Groundwater levels ranged between 7%2 and 28 feet below the existing ground surface. As noted in the Geotechnical Investigation report, BGC • suspects that the groundwater levels represent perched groundwater surfaces. Fluctuations in groundwater levels may occur seasonally and over a period of years because of precipitation, changes in drainage patterns, irrigation and other factors, including the planned installation of subsurface drains in conjunction with the planned remedial grading. Even with the planned • subsurface drainage, future irrigation may cause an overall rise in groundwater levels. SEISMIC SOURCES • No active faults are known to pass through the property, according to published geologic maps • (Dibblee, 1980; Crane, 1995; Graymer, et al. 1994). The nearest State-of-California-zoned, actives faults are the Calaveras fault located approximately 5 miles to the southwest and the Greenville fault located about 6 miles northeast of the site. As reported by BGC, no active or potentially active surface faulting was observed on the site. A "blind" thrust fault has been mapped northeast of the property by Dibblee (1980), Crane, (1995) and Graymer, et al., (1996), at the northern edge of the Livermore Valley. This mapped thrust fault is not considered active by the State of California or by local geotechnical • consultants. As reported by BGC, no active or potentially active surface faulting was observed • on the site. While the probability of ground rupture is considered low, as described in the ENGEO Geotechnical Reports, there is a high probability that the site and any improvements will be subject to strong ground shaking during the lifetime of the project. • 1 An active fault is defined by the State Mining and Geology Board as one that has had surface displacement within Holocene time (about the last 10,000 years) (Hart, 1994). The State of California has prepared maps designating • zones for special studies that contain these active earthquake faults. • D-2 i~~~~ • I N C O R P O R A T E D • • • • • • • • • • • • • • • • E • • X • • H • EXHIBIT E • I • JORDAN RANCH ANNEXATION • Funding and Acceptance • I • • T • • • • E • • • • • ~ - 4 _ _ e its"_ 7} J ~ f ~1l ~ L : .4 • I • Mission Valley Properties 7828.000.000 Jordan Ranch -Tract 8024 February 11, 2011 • FUNDING AND ACCEPTANCE OF RESPONSIBILITY BY THE DISTRICT An annual assessment is already being levied for properties in the Fallon Village GHAD under the provisions of the existing Plan of Control and Engineer's Report. Ultimately, an annual ~ assessment shall be levied on all annexed residential and nonresidential parcels with habitable • building areas within the Jordan Ranch development. 1. Activation of Assessment • The assessment shall be levied by the GHAD on each individual parcel beginning the first fiscal year following issuance of a building permit for that parcel. 2. Responsibility for GHAD Activities • The party that, on the date each Final Map is recorded within the GHAD annexation boundaries owns the developable parcels shown on that Final Map, shall have the responsibility to perform all the activities of the GHAD on property within that Final Map. Such responsibility shall automatically transfer to the GHAD at 9:00 a.m. on the day exactly three years after the first • residential building permit within the annexation area is issued by the City of Dublin provided that the items listed under item No. 4 in this section have been completed. This turn-over date may be extended at the sole discretion of the project developer provided that the assessments shall continue to be levied during the extension period and that notice of such extension is delivered to the GHAD Manager at least 30 days prior to the turn-over date. The petitioners for • formation of the GHAD intend that the approximately three-year period between the initial levying of the GRAD assessment and the GHAD becoming responsible to perform activities on property within each Final Map will allow the District to accumulate reserve funds without incurring significant expenses. 3. Ownership of the Open Space Ownership of the open space will pass from the owner/developers to the District on, or • approximately on, the date the District commences its activities and becomes responsible for • oversight of the actual physical maintenance of the open space as provided in this section. 4. Process for Transferring Responsibility for GHAD Activities • After the Transfer Eligibility Date for parcel(s), the process for transferring responsibility for performing GHAD activities on such parcel(s) shall be as follows: (a) In the calendar year of the Transfer Eligibility Date or in any subsequent year, at its • discretion, the developer may apply to the GRAD ("Transfer Application") to transfer the responsibility for performing GRAD Activities for parcel(s) to the District. • E-1 GEO INCORPORATE D • • • • Mission Valley Properties 7828.000.000 ,Jordan Ranch -Tract 8024 February 11, 2011 • (b) Within 45 days of receiving such notice, a representative of the GHAD shall verify that all the facilities for which the GHAD will have maintenance responsibility have been constructed and maintained according to the City-approved plans and specifications for the individual improvements, and that such facilities are operational and in good working order. • (c) Within 15 days of such inspection, the GHAD will send the developer a list ("Punch list") of all of the items that need to be constructed, repaired or otherwise modified. (d) The developer may notify the GHAD when it has completed the items identified on the • Punch list. (e) Within 30 days of receipt of such notice, the GHAD shall verify whether all Punch List items have been completed. If such items have been completed, the GHAD shall notify the • developer that the District accepts responsibility for performing all future GHAD Activities • on the parcel(s). (f) The GHAD shall confirm that the reserve requirement defined in the approved Engineer's • Report has been met. As part of the transfer, the developer of parcel(s) to be transferred will provide the GHAD, for its use, copies of the applicable geotechnical exploration reports, grading plans, corrective grading plans, improvement plans, field-verified geologic maps, as-built subdrain plans or other pertinent • .documents as requested by the GHAD. • E-2 • I N C O R P O R A T E D • • ~ ~5~ • • • • • • • • • • • • E • • X • • EXHIBIT F • • I • FALCON VILLAGE GEOLOGIC HAZARD ABATEMENT DISTRICT • Jordan Ranch Development B • GHAD Disclosure and Right of Access • I • T • • • • F • • • • • • u _v .,i F ~ ..i-. tip g ~ ~ -R. 1:. • ~~I • • DECLARATION OF RESTRICTIVE COVENANTS, RIGHT OF ENTRY AND DISCLOSURES REGARDING GEOLOGIC HAZARD ABATEMENT DISTRICT This Declaration of Restrictive Covenants, Right of Entry and Disclosures Regarding Geologic Hazard Abatement District (the "Declaration") is made this day of , 2011 (the "Effective Date"), by BJP-ROF Jordan Ranch, LLC, a California limited liability company ("Declarant"). • RECITALS A.
