R-value tests shell be conducted for all public and private roadway improvements to identify the minimum pavement structural section requirements for the site, unless otherwise not required by the City. 31. Type V cement stall be used for all concrete work coming in contact with the ground, unless otherwise indicated by the pre ject's soil engineer. 32. Grading and construction activites and the transportation of equipment and materials and operation of heavy grading equipment shall be limited to between the hours of 7:00 aim, and 5:00 p.m., Monday through Saturday.

Prior to commencement of any qork within the road right of way and/or connection to County mainteined storm drain, an enroachment permit from Public Works is required [(909) 396-5671], as well as proof of permit from the Los Angeles County Construction Division, Permit Section [(626) 458-31291 6. Prior to commencement of any work and/or discharge of drainage to a watercourse, a permit from the both the California Department of Fish and Game and U.S. Army Corps of Engineers may be required. 7. STATEMENT OF UNDERSTANDING As the Civil Engineer of the project, I have reviewed the Development Planning for Storm Water Management manual for the Standard Urban Stormwcter Mitigation Plan (SUSMP), and have proposed the implementation of the permanent Best Management Practices (BMP's) applicable to effectively minimize the negative impacts of the project's stormwater runoff. The selected BMP's will be installed per the approved plans and as recommended by the product manufacturer as applicable. The following BMPs may be used to satisfy SUSMP requirements: 1. Inserts in catch basins and storm drain inlets to filter storm water runoff or approved equal, prior to discharging to the ocean storm drain system. 2. Stenciling catch basins and storm drain inlets with prohibitive language (sush as: "NO DUMPING - THIS DRAINS TO OCEAN") and/ or graphical icons to discourage illegal dumping. 3. Regular sweeping of streets within the proposed development. 4. Provide trash cans and recycling receptacles along pedestrian walkways. 5. Post signs and prohibitive language and / or graphical icons to discourage illegal dumping. 6. Utilize non -toxic pesticides and fertilizers in the Icndscaing areas of the project. 7. Provide homeowners with information and brochures outlining good housekeeping practices for the use and dispose of household products. Encourage homeowners to use non -hazardous cleaning sustances and to recycle unwanted household hazardous materials into a Countywide Household Hazardous Collection Center.

The selected BMP's will be installed, monitored and maintained to ensure their effectiveness. The BMP's that i have not chosen for implementation are redundant or deemed not applicable to the proposed construction activities. If at any time, site conditions and/ or the City official warrant reevaluation and revisions of the chosen BMP's, the appropriate changes will be made without unnecessary delay. I am aware that failure to properly implement and maintain, while under construction, the BMP's necessary to prevent the discharge of pollutants from this project could r suit in significant penalties and/or delays.

Graded areas adjacent to fill slopes located at the site perimeter must drain away from the top of slope at the conclusion of each working day. 5. All silt and debris shall be removed from all devices within 24 hours after each rainstorm and be disposed of properly.. 6. A guard shall be posted on the site whenever the depth of water in any device exceeds two feet. The device shall be drained or pumped dry within 24 hours after each rainstorm. Pumping and draining of all basins and drainage devices must comply with appropriate BMP practices for dewatering operations. 7. Except as otherwise approved by the Grading Inspector, all removable protective devices shown shall be in place at the end of each working day or on weekends when the 5—day rain probability forecast exceeds 407.. 8. All loose soil and debris which may create a potential hazard to off —site property shall be removed from the site as directed by the Grading Inspector. 9. The placement of additional devices to reduce erosion damage within the site is left to the discretion of the Field Engineer. 10. Desilting basins may not be removed or made inoperable between November 1 and April 15 of the following year, without the approval of the Grading Inspector. 11. Erosion control devices are to be modified as needed as the project progresses and plans of these changes must be submitted for approval as required. 12. Add the following notes(or similar) to the plans to define the current state of construction. a. Storm drains and catch basins are (not) constructed. b. Streets are (not) paved, except as noted on the erosion control plans. c. Drainage devices are (not) constructed, except as noted on plans. 13. Stormwater pollution control requirements must be integrated into the Erosion Control plans per Title 26, Section 7010 of the County Code for any construction between October 15 and April 15. 14. Every effort should be made to eliminate the discharge of non—stormwater from the project site at all times. 15. Developers/contractors are responsible to inspect all Erosion Control Devices and make sure BMP's are installed and functioning properly at all times.
