41. Sound walls, meeting the design requirements contained in the MHCSD Design Guidelines, shall be installed on arterial streets when the adjacent development (or phased development) has abutting lots. The length of the sound wall shall match the total length of the lots abutting the arterial street plus an additional length that will close a gap to a previously constructed wall not more than 200 feet away. 42. The sound walls shall be constructed consistent with the MHCSD Design Manual, the Master Plan and as shown on the preliminary sound wall plans. The noise barrier may consist of a wall, berm, or combination thereof the exact location, height and character of the sound barrier shall be determined by a noise consultant approved by the County and the MHCSD. The sound barrier shall reduce outdoor noise levels at the center of backyards of proposed adjacent single-family residences to below 65 dBA Ldn/CNEL and as close to 60 dBA Ldn/CNEL as feasible. 43. Except when the MHCSD General Manager specifies otherwise, when a sound wall is installed on an arterial street, the adjacent street edge landscaping, sidewalk, and street curb & gutter shall also be installed. 44. The developer shall coordinate the MHCSD to locate bus stops within the residential portions of the project pursuant to the requirements of the MHCSD's TDM and TSM policy document. 45. Construction Traffic shall comply with the Construction Truck Management Plan administered by the MHCSD. Project construction plans shall include specifications to the contractor outlining compliance requirements. 46. To control erosion and sedimentation during project construction and operation, the developer shall comply with MHMP policies, MHMP mitigation measures, and Phase I and II NPDES permit requirements, including the preparation and implementation of a SWPPP that outlines BMPs to be followed to minimize erosion and sedimentation during project construction and operation. 47. All non-residential (i.e. Office, Industrial, Commercial, etc), uses must perform a pretreatment of all storm flows before the flows enter a public storm system. The design shall be in accordance with the Storm Water Master Plan Update and NPDES requirements. The MHCSD shall review and approve the plans and the specifications for the storm pretreatment prior to issuance of the building permit. 48. Water Quality Basins Mosquito Abatement: Plans for the implementation and maintenance of the water quality basins and any other storm drainage facilities involving open bodies of water shall be reviewed and approved by the MHCSD and if required by the MHCSD, reviewed by the mosquito Abatement District. Timing: Condition shall be met before approval of first Final Map. 49. Utilities: a. The Developers and contractors shall comply with Ordinance No. 4162 "Street Opening and Pavement Restoration Regulations". b. When any portion of an arterial street is to be included in a development's construction plans, then all of the buried utilities that are ultimately planned to be within the improvement area shall be installed as part of the street improvement project regardless if any of the utilities are required for any phase of the development associated with the street construction. Conduits or sleeves may be installed in lieu of the buried utility if approved by the MHCSD. c. Any phased development shall install all "in-tract" utilities required to serve the development. In addition, if any future adjacent or nearby phases of the development, or adjacent Neighborhoods, will depend on obtaining service from such utilities, then the utility lines shall be sized to serve these future developments. Any utility lines that are intended to be used by an adjacent development or Neighborhood shall be installed up to the phase or Tentative Map boundary line to make it available for future extension.
