On May 15, 2013, the City Council adopted the City of Moorpark Mission Statement, Priorities, Goals, and Objectives for FY 2013/2014. The following are the Departmental Goals and Objectives that coincide with the Council's desire for a recreation trail system at AVCP: VII. A. 20. Develop a conceptual plan and cost estimates for a formal walking path around the perimeter of Arroyo Vista Community Park. 26. Develop conceptual design plan and cost estimates for widening the access road within Arroyo Vista Community Park (A VCP) to accommodate bike lanes/paths and sidewalks. VI. C. 2. Install outdoor fitness equipment at one or more parks. On October 2, 2013 the City Council approved a conceptual plan for a proposed recreational trail system at Arroyo Vista Community Park (AVRC) and on November 20, 2013, Penfield and Smith was hired to prepare the plans and specifications for the Recreational Trail Improvements at AVRC. -,. ~ ... 49 Honorable City Council February 5, 2014 Page 2 DISCUSSION As presented to the City Council in October, the plan incorporates a safe route of travel for both pedestrians and bicyclists from the existing pedestrian bridge at the east end of the park, to the Arroyo Vista Recreation Center. Approximately 17 new parking spaces will be added to the park. The design was able to accommodate a separated bicycle path and pedestrian walkway along the entire length of the portion of the trail system that parallels the access road, from the east end of the park to the west, separated by lodge pole fencing on both sides of the bicycle path. Internally, the proposed trail system will incorporate an approximate one mile fitness loop around the perimeter of AVCP, with exercise stations set along the route. The design proposes the use of permeable concrete in the new parking areas, permeable asphalt for the bicycle trail, concrete for the sidewalks and decomposed granite paving for the surface material of the loop trail. The use of permeable pavement minimizes the storm water retention requirements of this project and increases the amount of storm water that will infiltrate back into the groundwater supply. The design proposes the creation of a detention basin at Parking Lot B to capture the portion of runoff from the non-permeable surfaces, such as the proposed concrete sidewalks, as well as existing surfaces, such as the asphalt parking lots and access road. In addition, the design provides for ADA compliant walkways to the softball fields and other open turf areas throughout the park. The plans and specifications have been made available for City Council review in the large conference room at City Hall. A copy is also attached to this staff report for public review. FISCAL IMPACT The engineers estimated cost to complete the project is $1.6 million inclusive of a 10% contingency. To date, a TOA Article 3 grant has been secured from the state in the amount of $132,000 for the pedestrian/bike path improvements from the pedestrian bridge to Arroyo Vista Recreation Center. Staff has applied for a LWCF grant from the State Parks Department in the amount of $500,000, which is equivalent to approximately 31 % of the total project costs. The LWCF grant requests a maximum and minimum grant award request. This ensures that the project may still be funded by LWCF grant but at a lesser level. The minimum grant request was $200,000. On January 15, 2014, the City Council allocated the funding for the project. This was required by the LWCF grant to show the City's commitment to the project. The LWCF is a reimbursement grant and, if awarded, will be used to reimburse the City sources of funding. The remaining project costs that would be paid from City funds is considered match money for the grant. If staff is successful in securing the grant, it is proposed that the remaining project costs will be allocated from a percentage of the General Fund (Fund 1000) as well as the Traffic System Management Fund (TSM) (Fund 2001) contingent upon the actual amount of LWCF grant monies awarded. Staff will evaluate 50 Honorable City Council February 5, 2014 Page 3 these funding options and return to City Council once the grant has been awarded and the project has gone out to bid. ENVIRONMENTAL DOCUMENTATION As this project involves the installation of hardscape, low-level lighting, and fitness equipment in an existing park, and there is no reasonable possibility that it would result in a significant effect on the environment, either individually or cumulatively in consideration of other reasonably foreseeable projects, it is the Community Development Director's determination that the project is categorically exempt from environmental review under the California Environmental Quality Act (CEQA) pursuant to Sections 15301 (Existing Facilities) and 15304 (Minor Alterations to Land) of the CEQA Guidelines. If this project is approved, staff will file a Notice of Exemption with the County Clerk. STAFF RECOMMENDATION Approve the plans and specifications for the recreation trail system project at Arroyo Vista Community Park.

AVCP PREPARATION Protect structures, utilities, sidewalks, pavements, and other facilities from damage caused by settlement, lateral movement, undermining, washout, and other hazards created by earthwork operations. Provide erosion control measures to prevent erosion or displacement of soils and discharge of soil-bearing water runoff or airborne dust to adjacent properties and walkways. Tree protection is specified in the "Site Clearing" section. Prepare subgrade and place base materials in accordance with sections 301-1.2 and 301-2, respectively, of the Reference Specification. DEWATER ING Prevent surface water and subsurface or ground water from entering excavations, from ponding on prepared subgrades, and from flooding Project site and surrounding area. Protect subgrades and foundation soils from softening and damage by rain or water accumulation. EXCAVATION General: Shall be to the contours and dimensions indicated. Keep excavations free from water and debris while construction is in progress. Notify the Owner immediately in writing where it becomes necessary to remove hard, soft, weak, or wet material to a depth greater than indicated. Unless otherwise indicated, concrete placed below grade will be formed and excavations shall allow for placement and removal of forms. Side cuts shall be cribbed and shored as required. Explosives: Do not use explosives. Unclassified Excavation: Excavation is unclassified and includes excavation to required subgrade elevations regardless of the character of materials and obstructions encountered. STABILITY OF EXCAVATIONS Comply with local codes, ordinances, and requirements of authorities having jurisdiction to maintain stable excavations. Unshared Temporary Excavations: Unshared temporary excavations may be sloped back at 1 to 1 (horizontal to vertical) or flatter. Where sloped embankments are used, the tops of the slopes should be barricaded to prevent vehicles and storage loads within seven feet of the tops of the slopes. If the temporary construction slopes will be maintained during the rainy season, City of Moorpark EARTH MOVING 31 20 00 -4 77 construct berms along the tops of the slopes where necessary to prevent run-off water from entering the excavation and eroding the slope faces. 3.5 EXCAVATION FOR STRUCTURES -NOT USED 3.6 EXCAVATION FOR WALKS AND PAVEMENTS A. Excavate surfaces under walks and pavements as necessary to permit placing of at least 2 feet under concrete pavement and at least 1 foot under asphalt concrete pavement of non- expansive soils (Expansion Index less than 20) engineered fill beneath indicated elevations, and grades. 3.7 EXCAVATION FOR UTILITY TRENCHES A Excavation made with power-driven equipment is not permitted within two feet of any known utility or subsurface construction. For work immediately adjacent to or for excavations exposing a utility or other buried obstruction, use hand or light equipment excavation. Start hand or light equipment excavation on each side of the indicated obstruction and continue until the obstruction is uncovered or until clearance for the new grade is assured. Support uncovered lines and other existing work affected by the excavation work of this Section until approval for backfill is granted by the geotechnical engineer. Immediately report damage to utility lines or subsurface construction to the Owner. B. Where unidentified existing utilities are encountered, determine whether these are active or abandoned. Remove interfering portions of abandoned utilities and cap or plug open ends of pipe to remain. The cap or plug must seal the opening in such a manner that would permit remaining portions of the utility to be reactivated. Notify Owner for instructions on utilities which are determined to be active. Do not proceed without instructions, except to correct an immediate hazard or emergency condition. Relocation work performed on an active utility without obtaining prior approval from Owner shall be done at the Contractor's expense and liability. C. In areas where compacted backfill has been placed, additional consolidation may occur after completion due to changes in moisture content and surcharge. Utility connections crossing this backfill, and improvements adjoining the building at the backfill line shall be installed taking into account this additional consolidation, or sufficient time shall be scheduled between backfilling operations and such improvements to allow this consolidation to take place. Damage to utilities or other improvements due to Contractor's negligence in regard to this paragraph shall be repaired at the Contractor's expense. D. Protect newly backfilled areas and adjacent structures, slopes, or grades from traffic, erosion settlement, and any other damage. Repair and re-establish damaged or eroded grades and slopes and restore surface construction prior to acceptance. E. Cutting Pavement, Curbs, and Gutters: Saw cut with neat, parallel, straight lines one foot wider than trench width on each side of trenches and one foot beyond each edge of pits. If an existing pavement joint or cracked area is within two feet outside of a designated sawcut line shown on the Drawings, removal and resurfacing shall be to that joint, and/or shall include the crack or cracked area, unless otherwise approved by Engineer. F. Contractor shall pothole at all identifiable crossings of existing utilities prior to any trenching operations and provide Engineer with a survey of the top elevations (and bottom elevations, if applicable), of possible interferences so that an evaluation of necessary adjustments to the current profile or alignment may be made. Additionally, Engineer shall be given the opportunity to view possible conflicts in the field prior to providing revised designs. G. Provide a minimum cover from grade of 3 feet for water mains and gas mains, unless otherwise noted. Storm drains and sewers shall be to the depths indicated. Where AVCP City of Moorpark EARTH MOVING 31 20 00 -5 78 3.8 3.9 settlements greater than the tolerance allowed herein for grading occur in trenches and pits due to improper compaction, excavate to the depth necessary to rectify the problem, then backfill and compact the excavation as specified herein and restore the surface to the required elevation. H. Keep excavations free from water while construction is in progress. I. Notify the Owner immediately in writing if it becomes necessary to remove rock or hard, unstable, or otherwise unsatisfactory material to a depth greater than indicated. Excavate large rock, boulders, and other unyielding material to an overdepth at least 6 inches below the bottom of the pipe, conduit, duct and appurtenances, unless otherwise indicated or specified. Over-excavate soft, weak, or wet excavations to an overdepth at least 12 inches below the bottom of the pipe, conduit, duct or appurtenances unless otherwise indicated or specified. J. Excavate trenches to indicated slopes, lines, depths, and invert elevations. K. Excavate trenches to uniform widths to provide a working clearance on each side of pipe or conduit. Excavate trench walls vertically from trench bottom to 12 inches higher than top of pipe or conduit, except where sloping of sides is allowed. Sides of trenches shall not be sloped from the bottom of the trench up to the elevation of the top of the pipe. See plans for detail. L. At the option of the Contractor, the excavations may be cut to an overdepth of not less than 4 inches and refilled to required grade as specified. M. Trench Bottoms: Excavate and shape trench bottoms to provide uniform bearing and support of pipes and conduit.

PART 3 EXECUTION 3.01 Subgrade: Verify subgrade preparation, grade, and conduct permeability and density tests for conformance to project requirements and is acceptable for installation of pervious concrete. (See PSCA 'Section 31 Subgrade Guidelines for Pervious Concrete' that accompanies this document.) 3.02 Recharge Basin (Detention Basin): When base material is used under pervious concrete for water recharge, it shall be composed of uniform sized aggregate conforming to ASTM C33, minimum size 6. For minimum void content, refer to civil or geotechnical contract documents. 3.03 Formwork: Form materials: any material permitted by AHJ and of sufficient strength and stability to support mechanical equipment without deformation of plan profiles following spreading, strike-off and compaction operations. 3.04 Mixing and Hauling: A. Production: Pervious concrete shall be manufactured and delivered in accordance with applicable sections of ASTM C 94 or ASTM C 685. B. Mixing: Pervious concrete shall be produced in central mixers, transit mixers or in volumetric mixers. C. Delivery: Deliver pervious concrete directly from the mixer by means of conveyer as close as possible to final position. D. Discharge: Each truckload will be visually inspected for consistency of concrete mixture. Job site water additions are permitted to obtain and maintain the required mix consistency throughout the discharge. 4 140 Discharge shall be a continuous operation. Concrete shall be deposited as close to its final position as practical and such that discharged concrete is incorporated into previously placed plastic concrete. 3.05 Placing and Finishing: Shall comply with the content of the National Ready Mixed Concrete Association's 'Text Reference for Pervious Concrete Contractor Certification' with the following provisions: A. Internal vibration shall not be permitted. Use mechanical screed equipment. Do not use hand screeds except in confined and small areas. Cross roll compacted concrete to remove any screeding and compaction marks on the concrete surface. B. Compact to the required cross-section and shall not deviate more than:±: 3/8 inch in 10 feet from profile grade. 3.06 Jointing A. Joints shall be installed at locations and to depths shown on the project plans. B. Control (contraction) joints shall be installed at regular intervals not to exceed 1.5 times the width of the placement or 20 feet, or in accordance with approved joint placement plan. The control joints shall be installed at v. the thickness of the pavement but not to exceed 1-1/2". These joints can be installed in the plastic concrete or saw cut after the concrete has hardened. New joints in plastic concrete or recently hardened concrete shall align with joints in older concrete. Joints abutting curbs and other fixed concrete shall be installed within 10 degrees of perpendicular to the older concrete as possible. C. Install joints to match approved sample. D. Transverse construction joints: Install whenever placing is suspended for 20 minutes or whenever concrete is no longer workable. E. Do not dowel longitudinal joints between successive placements. F. Isolation joints: Use when abutting fixed vertical structures. Place isolation material before concrete.is placed and to the depth of the pavement section. 3.07 Curing: A. Final curing procedures shall begin no later than 20 minutes after the concrete has been discharged from the mixer. The pavement surface shall be covered with a minimum of six (6) mil thick white or clear polyethylene sheet or other approved covering material. In cold weather black plastic may be used to aid in heat retention. The cover shall prevent air infiltration to the fresh concrete and shall overlap all exposed edges and shall be secured to prevent dislocation due to winds or adjacent traffic conditions. B. The curing cover shall remain securely in place for a minimum of7 days. No vehicular traffic shall be permitted on the pavement until curing is complete and no truck traffic shall be permitted for at least 14 days. 3.08 Quality Control: 5 141 A.
