vii. Temporary stabilization and reseeding of disturbed soil areas as rapidly as feasible;

viii. Wind erosion controls;

ix. Tracking controls;

x. Non-stormwater management measures to prevent illicit discharges and control storm water pollution sources;

xv. Retention, reduction, and proper management of all storm water pollutant discharges on site to the Maximum Extent Practicable (MEP) standard.

Minimum Erosion and Sediment Controls

i. Erosion prevention is to be used as the most important measure for keeping sediment on site during construction;

ii. Sediment controls are to be used as a supplement to erosion prevention for keeping sediment on-site during construction;

iii. Slope stabilization must be used on all active slopes during rain events regardless of the season and on all inactive slopes during the rainy season and during rain events in the dry season; and

iv. Permanent revegetation or landscaping must be implemented as early as feasible.

9. FLOW AND ACCEPTANCE OF WATER

It is anticipated that storm, tidal, well and pump discharge, surface and possible ground or other waters (WATERS) will be encountered at various times and locations during the work. Such WATERS may interfere with CONTRACTOR's operations and may cause damage to adjacent or down-stream private and/or public property by flooding, lateral erosion, sedimentation, or pollution if not properly controlled by the CONTRACTOR. The CONTRACTOR, by submitting a bid, assumes all of said risk and the CONTRACTOR acknowledges that its bid was prepared accordingly.

In addition, by entering into this CONTRACT, the CONTRACTOR, his subcontractors, and material suppliers acknowledge that there are inherent risks to their workmen, equipment, materials, supplies, and other personal property by conducting work in and around OWNER facilities from WATERS; that damages and injuries to his workmen, completed and partially completed PROJECT works, construction site water quality features/BMPs, equipment, materials, supplies, and other property could occur at any given time, especially if occupying the PROJECT site or conducting work during the storm season (October 1st15th to April 3015th); and that OWNER is not responsible or liable for the CONTRACTOR’s, subcontractor’s, and/or material supplier’s damages caused by WATERS.

The CONTRACTOR by submitting a bid assumes all of said risk, responsibility, and liability at no additional cost to the OWNER. The CONTRACTOR shall repair/rebuild/replace any damages or losses to PROJECT (while CONTRACTOR is in possession of PROJECT) at no additional cost to the OWNER beyond his original bid (and all extra work approved prior to the time of damage by WATERS). The CONTRACTOR acknowledges that he/she considered and included these issues and risks in his submitted bid for the PROJECT.

The CONTRACTOR shall conduct its operations in such a manner WATERS may proceed without diversion or obstruction along existing street and drainage courses. Equipment, materials, and supplies shall not be placed or stockpiled in any way that they may create an obstruction to WATERS. Drainage of WATERS from existing or proposed storm drains and catch basins shall be maintained at all times. Diversion of WATERS for short reaches in order to protect construction in progress will be permitted if public and/or private properties are not damaged or, in the opinion of the ENGINEER, are not subject to the probability of damage. CONTRACTOR shall at no cost to OWNER obtain written permission from the appropriate public agency and/or property owner before any diversion of WATERS will be permitted by the ENGINEER.

By entering into an CONTRACT with the OWNER, the CONTRACTOR acknowledges that the ENGINEER’s permission and/or approval shall in no way relieve the CONTRACTOR from his responsibility and/or liability, for protecting at all times, adjacent and downstream properties, including the PROJECT site, from damages due to temporary: stream bank/channel alterations;

excavation and/or fill; channelization; flow diversions; check dams, sediment, groundwater, water quality basins, and/or other impoundments not shown on the Plans but chosen and implemented by the CONTRACTOR, at his option, as his means and methods of constructing the PROJECT.

During the course of controlling WATERS, the CONTRACTOR shall conduct construction operations to protect WATERS from being polluted with concrete, grout, mortar or concrete washout, chemicals, sediment, fuels, oils, bitumens and other asphalt derivatives, or other harmful materials, and shall be responsible for removing said materials in the event protective measures are not effective.

Construction site shall be maintained in such a condition that an anticipated storm does not carry sediment, wastes, or pollutants off site.

Discharges of material other than stormwater are allowed only when necessary for performance and completion of construction practices and where they do not: cause or contribute to a violation of any water quality standard; cause or threaten to cause pollution, contamination, or nuisance; or contain a hazardous substance in a quantity reportable under Federal Regulations 40 CFR Parts 117 and 302, or any other law or applicable regulation.

Potential pollutants include but are not limited to: sediment, vehicle/equipment fuels, oils, lubricants, and hydraulic, radiator or battery fluids; vehicle/equipment wash water and concrete mix wash water; concrete, detergent or floatable wastes; wastes from any engine/equipment steam cleaning or chemical degreasing; solid or liquid chemical spills; wastes from sealants, limes, and solvents; and super-chlorinated potable water line flushings.

During construction, disposal of such materials shoalluld occur in a specified and controlled temporary area on-site, physically separated from potential storm water run-off, with ultimate disposal in accordance with local, state, and federal requirements.

10. SURVEYING SERVICES

CONTRACTOR shall be made aware that OWNER has a work schedule with limited surveying services available on Friday, and that surveying services cannot be guaranteed on all Fridays.

CONTRACTOR is required to keep OWNER informed in advance of his schedule to assure surveying services are available for construction of Project as described in the "SURVEYING" Subsection of the “PERFORMANCE” Section of the General Conditions. CONTRACTOR shall submit a formal written request for surveying services to OWNER no less than forty-eight (48) hours in advance of his need for such services. Failure by CONTRACTOR to submit a written request in a timely manner may not guarantee that such services will be available when required, and surveying services cannot be guaranteed on Friday regardless.

The CONTRACTOR is to make every effort to avoid disturbing or destroying Survey Control Points set by the County of Orange Survey Crews (OC Survey). If destruction of a Control Point is unavoidable, CONTRACTOR is required to contact the OWNER at least 48 hours in advance .

This will enable OC Survey crews to assess the relevance of said Control Point and

1. Allow its destruction; or

2. Allow OC Survey time to relocate said Control Point and not affect the project schedule.

If this procedure is not followed, the cost for replacing or relocating or re-setting of dislocated Survey Control Points as specified in these General Provisions and as deemed necessary by the OWNER or OWNER Surveyor. Is considered included in various items of work involved and no additional compensation will be allowed therefor.

CONTRACTOR‘s attention is directed to Section 8771 (b) of the Business and Professions Code and submittal of appropriate documents (Corner Record or Record of Survey) with the County Surveyor’s office for review and approval.

The cost of all surveying, to the lines and grades shown on the plans, shall be considered as included in the various items of work and no separate payment will be allowed therefor.
