Monte Sereno Municipal Code Ch. 9.04 Grading

The primary purposes of this Chapter are to protect life, limb and property, to promote and enhance the general public welfare and a superior community environment, and insofar as it is economically feasible, to ensure the maximum possible preservation of the natural scenic character of major portions of the City establishing minimum standard and requirements relating to land grading, excavations and fills, and procedures by which these standards and requirements may be enforced. It is intended that this Chapter be administered with the foregoing purposes in mind and with a view to:

A. Ensuring that future development of lands, particularly in the hillside areas of the City occurs in the manner most compatible with surrounding areas and so as to have the least adverse effect upon other persons or lands, or upon the general public.

B. Ensuring that soil will not be stopped and removed from lands within the City, leaving them barren, unsightly and susceptible to erosion, subsidence and faulty drainage.

C. Ensuring the regulation of grading private property in order to control erosion, control sedimentation and to protect the water quality of watercourses, water bodies and wetlands.

D. Ensuring the planning, design and development of building sites in such fashion as to provide the maximum in safety and human enjoyment, while adapting development and taking advantage of the best use of the natural terrain.

E. Encouraging and directing special attention toward retaining and protecting, insofar as practical, the natural planting and a maximum number of existing trees.

(Ord. 118 § 1 (part), 1999)

A. This Chapter sets forth rules and regulations to control excavation, grading, and earthwork construction, including fills or embankments; establishes the administrative procedure for issuance of permits; and provides for approval of plans and inspection of grading construction.

B. The provisions of this Chapter are supplementary and in addition to the zoning and subdivision regulations of the City, and shall be read and construed in connection with and as an integrated part of the zoning and subdivision chapters and the patterns of land development control established thereby.

C. In the event of conflict between this Chapter and Chapter 33 of the most recently adopted Uniform Building Code entitled "Excavation and Grading," this Chapter shall take precedence.

19. The extent of unprotected slopes allowed at any one time and the time said slopes are allowed to remain unprotected.

20. Other conditions deemed necessary by the City Engineer and based on accepted engineering practices.

Fees shall be collected by the City as established by resolution of the Council.

(Ord. 118 § 1 (part), 1999)

A. Filing fees, permit transfer fees, penalty fees and site investigation fees are not refundable.

B. In cases of a reduction of planned work, the approval of an amended permit by the City Engineer and satisfactory completion of the work covered by the amended permit, the permittee may apply to the City Engineer within thirty (30) days after issuance of the certificate of completion for a refund of a portion of the permit fee based on the revised cost of the work in the amended permit.

(Ord. 118 § 1 (part), 1999)

A. Surety Required. If the City Engineer determines that the nature of the proposed work is such that, if left incomplete, it will interfere with any natural or artificial drainage, or will endanger persons or public or private property, or will constitute a nuisance or if he determines that the proposed work involves the removal or deposition of more than fifty (50) cubic yards of material are moved, the applicant for the grading permit shall post with the City Engineer a surety executed by the applicant and secured, at the option of applicant, by (1) a corporate surety bond executed by a surety company authorized to do business in the State of California, or (2) by deposit with the City of cash money or its equivalent, or (3) by deposit with the City of an instrument of credit from a financial institution subject to regulation by the State of California or the Federal government pledging that the funds necessary to meet the performance are on deposit and guaranteed for payment upon demand and agreeing that the funds designated by the instrument shall be trust funds for the purposes set forth in the instrument. The form of the bond and the security shall be subject to approval by the City Engineer and the City Attorney.

B. Amount of Surety.

1. The amount of the surety shall be based upon the cost of the total number of cubic yards of material moved, plus the cost of all drainage erosion control or other protective devices or work necessary to eliminate geological hazards or to protect persons or public or private property. The amount of surety shall reflect market value to perform subject work or revert site back to original condition.

2. When the rough grading has been completed in conformance with the requirements of this Chapter, the City Engineer may at its discretion consent to a proportionate reduction of the surety to an amount estimated to be adequate to insure completion of the grading work, site development, or planting remaining to be performed. The costs referred to in this Section shall be as estimated by the City Engineer.

C. Conditions of Surety. Among other appropriate provisions, every bond shall include the following conditions to which the principal and surety shall each be bound:

1. To comply with all of the provisions of this Chapter and all other applicable laws, ordinances, rules, and regulations.

2. To comply with all of the terms and conditions of the permit for excavation or fill to the satisfaction of the City Engineer.

3. To complete the work contemplated under the permit within the time limit specified in the permit. The City Engineer may, for sufficient cause, extend the time specified in the permit, but no such extension shall release the surety.

4. To pay all reasonable costs incurred or expended by the City including but not limited to court costs and attorney's fees, in doing or causing to be done any of the work set forth in the permit, any other work which in the judgment of the City Engineer is required to be done as a result of any work or activity done under the permit, or any abatement of any nuisance created by any work or activity done under the permit, or in collecting money or damages in connection with any of the foregoing.

D. Term of Surety. The term of the bond shall begin on the date of its posting and shall end on the satisfactory completion of the terms and conditions of the permit. Completion shall be evidenced by a certificate of completion to be issued by the City Engineer and filed with the records of the permit. A copy of the certificate shall be furnished to any interested party upon request.

E. Notice of Default. Whenever the City Engineer finds that a default has occurred in the performance of any term or condition of any permit, he shall give written notice thereof separately to the permit holder and to his surety. Said notice shall state the work or other things necessary to be done in order to cure said default, its estimated cost, if known, and the period of time deemed reasonably necessary by the City Engineer to complete said work, and to do such other things which are necessary to be done in order to cure said default. Said notice shall be served personally or by deposit in the United States mail in a sealed envelope, with postage fully prepaid, addressed to the permit holder and to his surety at the mailing address, or, if there is no mailing address, the business address, shown in the application or in the surety, as the case may be.

F. Duty of Surety. Upon service of the notice of default, the surety shall be obligated to have the work done within the time specified in the notice.

G. Disposition of Cash Security. If cash money or its equivalent or an instrument of credit has been deposited to secure the bond, and if notice of default has been served upon the permit holder and he has failed to do the work and other things required to be done by the notice within the time specified in the notice, the City Engineer may use such deposit in order to have such work and other things done, by contract or other means in the discretion of the City Engineer. The balance, if any, shall be returned to the depositor after completion of the work and other things.

H. Right of Entry. In the event of any default in the performance of any term or condition of the permit, the surety, if any, or any person employed or engaged on its behalf, or the City Engineer or any person employed or engaged on his behalf, shall have the right to go upon the premises to complete the work and do other things required by the permit. It shall be unlawful for any person in any way to hinder, obstruct, or prevent such entry.

I. Erosion and Sediment Control Surety. If a grading permit requires the preparation of an erosion and sediment control plan, the applicant shall secure the performance of the work described and delineated in the plan as follows:

1. The City Engineer shall review the interim and final erosion and sediment control plan and estimate to determine the bond amount to cover the erosion and sediment control plans, its implementation and maintenance. If the approved engineer's estimate of cost of the erosion and sediment control plans are less than Ten Thousand Dollars ($10,000) a cash bond in that amount is to be provided to the City. If the approved engineer's estimate of cost of construction of the erosion and sediment control plans is more than Ten Thousand Dollars ($10,000) then a cash bond of at least Ten Thousand Dollars ($10,000) shall be posted with the City to cover the work outlined in the erosion and sediment control plans. After reviewing the grading plans and the erosion and sediment control plans, the City Engineer shall determine the final amount of the cash bond. If permanent site landscaping is an element of the final erosion sediment control plan, then the value of that improvement may be deducted if a separate landscape surety is being required.

2. When a cash bond amount has been determined, the differences between the cash bond and the total surety requirement shall be provided to the City in the form of bonds or other surety acceptable to the City Attorney. As part of the erosion and sediment control plan, the applicant shall submit a time schedule outlining specific dates when each element of the plan is proposed to be completed. After the schedule has been agreed to by both the City and the applicant, this schedule shall be the triggering mechanism for the City performing the work in lieu of the applicant's contractor. If the contractor has not or cannot install the interim and final erosion and sediment control plan items by scheduled dates, the City, at its option, can install the items necessary to protect the project site and other property. Such items of work shall be paid for from the applicant's cash deposit. In addition, any items of erosion and sediment control plan work that have been installed and are not being adequately maintained to protect the site as determined by the City Engineer shall be remedied, and any associated cost shall be paid for from the applicant's cash bond. During storm periods, if the applicant's contractor cannot be contacted or cannot perform required work needed to protect the site as determined by City Engineer, the City shall cause the work to be performed and any associated costs shall be paid from the applicant's cash bond.

3. In accepting the grading permit, the applicant acknowledges the right of the City or its representative to come on to the applicant's property to perform any or all needed work, as previously outlined in this Section.

4. Notice of Default. Whenever the City Engineer finds that a default has occurred in the performance of any term or condition of any permit, he shall give written notice thereof separately to the permit holder and to his surety. Said notice shall state the work necessary to be done in order to cure said default, its estimated cost, if known, and the period of time deemed reasonably necessary by the City Engineer to complete said work, and to do such other things which are necessary to be done in order to cure said default. Said notice shall be served personally or by deposit in the United States mail in a sealed envelope, with postage fully prepaid, addressed to the permit holder and to his surety at the mailing address, or, if there is no mailing address, the business address, shown in the application or in the bond, as the case may be.

5. If any part of the cash bond needs to be expended by the City to undertake work items outlined in subdivision (2) of this subsection, the associated grading permit is automatically terminated. The applicant shall submit a new grading permit application, a new grading plan with an erosion and sediment control plan acceptable to the City Engineer and provide the appropriate bonds and fees required by the City. There is no guarantee that a new permit will be issued.

6. When all grading as shown in the approved grading plans has been completed, and all items of work in the erosion and sediment control plan have been installed to the satisfaction of the City Engineer, the applicant may request exoneration of grading and final erosion and sediment control plan bonds. The City Engineer shall review all requests for exoneration of grading bonds, but final erosion and sediment control plan bonds shall not be considered for exoneration until the site has weathered a storm season from October 1st to April 15th with final erosion and sediment control plan elements including permanent landscaping in place. The City Engineer can, upon request, make a determination on minor grading projects whether or not the erosion and sediment control plan bonds need to be held through a storm season.

(Ord. 118 § 1 (part), 1999)

When an application is approved and a permit issued, one set of plans and accompanying documents shall be clearly marked as approved and shall be returned to the applicant. This set shall be kept available for reference at the job site during grading and construction. The applicant may furnish additional sets of plans and documents for notation as reviewed for return to the applicant for his use.

(Ord. 118 § 1 (part), 1999)

A. Any changes in the plans, grades, or extent of work shall be submitted to the City for written approval and incorporated into the permit, accompanied by any necessary fees, before any change in the approved work is begun. The City Engineer may amend the permit to approve altered plans, or may deny approval of the changes.

B. Failure to obtain prior approval for any change in the work shall be cause for the City Engineer to order suspension of all work until approval is obtained, and may result in revocation of the permit if he deems the changes will increase the hazard to adjoining properties or public roads, or otherwise be detrimental to public welfare.

(Ord. 118 § 1 (part), 1999)

A. Any transfer of a permit from the permittee to another party is prohibited unless approved by the City Engineer.

B. The transferee shall agree to comply with the requirements and conditions of the original permit and to any modification thereof that may be required because of changes in the condition of the site or change in plans since the permit was issued. The transferee shall furnish the required sureties before the transfer of the permit will be approved.

(Ord. 118 § 1 (part), 1999)

A. Grounds. A permit may be suspended or revoked if the City Engineer finds that:

1. Conditions at the site vary appreciably from those shown and stated in the application and development plans;

2. Grading or construction does not conform to the approved plans, grades, interim or final erosion and sediment control plan, or other conditions of the permit;

3. Cessation of work before completion that has left the site in a condition hazardous to the public or to the adjacent properties, and the permittee has not complied with reasonable requirements for completion of the work within the time specified in the permit or an approved extension of time;

4. The permittee does not comply with reasonable requirements to safeguard the workers, the public, or other persons acting in a lawful manner, during grading or construction operations;

5. In transporting materials or in the operation of equipment the applicant causes materials or litter to encroach, obstruct, or be deposited on pavement or in drainage channels within the public right-of-way, or causes unauthorized obstruction or diversion of drainage channels within the site area; or

6. The permittee fails to have a qualified inspector working under the geotechnical engineer on the site during grading or construction, when required, or failure to have the work under proper supervision at all times.

B. Procedure.

1. Upon determination that grounds for revocation or suspension of a grading permit exist, the City Engineer may fix a time and place for a hearing on revocation or suspension and shall give written notice thereof separately to the permit holder and to the surety, if any, stating in general terms the grounds for revocation or suspension. Said notice shall be given at least five (5) days before the hearing, and it shall be served personally or by deposit in the United States mail in a sealed envelope, with postage fully prepaid, addressed to the permit holder and to his surety at the mailing address, or, if there is no mailing address, the business address, as shown in the application or in the bond, as the case may be.

2. Within thirty (30) days of the conclusion of the hearing the City Engineer shall make findings and decision and file same in his office and shall serve a copy thereof separately upon the permit holder and his surety, if any, in the manner provided above for service of notice of hearing.

C. Exception. If the City Engineer determines that emergency conditions exist on the site which constitute a threat to the public health, safety, and welfare, the grading operation in its entirety or portion thereof shall immediately cease.

(Ord. 118 § 1 (part), 1999)

A. Upon notification from the City Engineer of the suspension of the permit, the permittee shall cease all work in connection with the permit with the exception of the work necessary to correct the conditions which caused the suspension of the permit. The permittee shall proceed at once to correct said objectionable or emergency conditions.

B. If the permittee fails to correct said objectionable or emergency conditions, the City Engineer may cause the work necessary to correct said conditions to be done, and the City Engineer may take action against the permittee's surety to cover the cost of performing the work.

C. Any permit which has been suspended may be either reinstated or revoked by the City Engineer.

D. Whenever a permit has been revoked, work shall not commence until a new application has been filed and approved incorporating the necessary revisions required to fulfill the intent of this Chapter, and a new permit has been issued.

(Ord. 118 § 1 (part), 1999)

The City Engineer and other authorized City representative shall have the right to enter the site at all times to insure compliance with permit conditions.

(Ord. 118 § 1 (part), 1999)

All work involving a fill intended to support improvements, or grading where the City Engineer determines special conditions or unusual construction hazards exist, shall be performed under the inspection of a civil engineer and/or geotechnical engineer and shall be designated "supervised development work." Work other than supervised development work shall be designated "regular development work."

(Ord. 118 § 1 (part), 1999)

A. For regular development work the City Engineer or designated representative, upon notification from the permittee or his agent, shall inspect the work at the following stages of the work and shall either approve the portion then completed or shall notify the permittee or their agent of the inspection results.

1. Initial. When the site has been cleared of vegetation and unapproved fill and has been scarified, benched or otherwise prepared and before any fill is placed.

2. Rough. When rough grading has been completed and approximate final elevations have been established; drainage terraces, swales and other drainage devices have been graded and are ready for paving; and berms have been installed at the top of slopes.

3. Final. When work has been completed with all drainage devices, systems and facilities installed and slope planting established.

B. In addition to the inspections specified above, the City Engineer may (1) make such other inspections as he deems necessary to determine that the work is being performed in compliance with the requirements of this Chapter, and (2) require investigations and reports by a geotechnical engineer and/or engineering geologist.

(Ord. 118 § 1 (part), 1999)

The following inspections and reports shall be required for supervised development work:

A. It shall be the responsibility of the geotechnical engineer and/or civil engineer to inspect the operations and provide qualified full-time inspection to assure compliance of the work with the approved development plans and with the requirements by the City Engineer and shall certify in writing to the satisfactory completion of each stage of the work specified in Section 9.04.270.

B. The geotechnical engineer shall submit compaction data and geotechnical engineering recommendations made during the development operation to the City Engineer.

C. The civil engineer shall submit inspection reports regarding drainage facilities, lot drainage and finish grades to the City Engineer.

C. If corrections need to be made to protect the site, the items of work and time scheduled to perform to the work by the contractor shall also be noted.

(Ord. 118 § 1 (part), 1999)

Erosion control measures shall be installed for all rainy season active and passive construction projects. Grading operations may commence in or continue through rainy season, at the discretion of the City Engineer, provided that erosion control measures in conformance with approved plans are immediately installed and are kept continuously in place, as the case may be. The only control measures which may be altered are those in direct conflict with daily construction activity, as long as said controls are replaced at the end of construction activity that day or start of storm event. Erosion control measures shall include, but not necessarily be limited to, the following:

A. The Erosion and Sediment Control Handbook and California Storm Water Best Management Practices Hand Book shall be used as guides for the design and suitability of erosion and sediment control measures.

B. The faces of cut and fill slopes shall be protected against damage by erosion and the methods utilized for each protection must offer effective erosion control prior to the beginning of, as well as during, the rainy season.

C. Where graded slopes are steeper than three (3) feet horizontal to one (1) foot vertical or are higher than ten (10) feet, they shall be protected with a temporary soil stabilization measure such as jute matting or an equivalent mulch until planting is established.

D. The surface of all cut slopes higher than five (5) feet and all fill slopes higher than three (3) feet shall be permanently protected against damage by erosion by the planting and establishment of protective vegetation.

E. Slopes higher than fifteen (15) feet shall be planted with one shrub per one hundred (100) square feet of slope and one (1) tree per four hundred (400) square of slope. Geometric spacing should be avoided; massing of trees is encouraged. Size and species of plant material shall be subject to review.

F. The planting of seeding or vegetation protection must be effective. If the vegetation does not grow and offer proper protection, it must be replanted or reseeded.

G. The maintenance of vegetative protection on graded slopes shall be the responsibility of the permittee and shall be guaranteed until the vegetation is well established as determined by the City Engineer or until the maintenance is officially assumed by another party approved by the City Engineer.

H. Sediment control facilities shall be operational prior to the beginning of the rainy season and must effectively prevent sediment from being transported downstream.

I. The outlet from any sedimentation basin must be designed to handle 1.5 times the maximum design inflow.

J. A standby emergency crew must be provided by the permittee and must be available at all times during the rainy season to repair and maintain the erosion and sediment control devices.

K. Erosion control materials must be stockpiled on the site for emergency repairs during the rainy season.

L. Trunk storm drain facilities, if determined by the City Engineer to be essential to the operation of the erosion control measures, shall be installed in place with grading operations and shall not be delayed until grading completion.

M. After each rainfall, the permittee shall inspect all erosion and sediment control devices and shall clean them and repair any damage.

N. Erosion control devices must be installed where drainage facilities discharge into natural channels. The devices may be rip-rap or concrete channel protection, stilling basins, check dams, drop structure or other devices which will effectively minimize erosion in the opinion of the City Engineer.

O. Erosion control planting, See Section 9.04.456.

(Ord. 118 § 1 (part), 1999)

If the soil or civil engineer finds that the work is not in conformance with this Chapter or with the plans approved by the City Engineer with good accepted practices, they shall immediately notify the permittee and the City Engineer verbally and in writing of the non-conformity and of the corrective measures to be taken.

(Ord. 118 § 1 (part), 1999)

If the civil engineer, or the geotechnical engineer, or the geologist are relieved of or otherwise terminate duties prior to completion of the work shown on the grading plan, they shall report the fact in writing to the City Engineer within forty-eight (48) hours with a report on the status of the work.

(Ord. 118 § 1 (part), 1999)

In addition to the requirements of the permit, the permittee shall comply with all laws, ordinances, and regulations of the State Department of Industrial Relations, relating to the character of the work, equipment, and labor personnel involved in the project.

(Ord. 118 § 1 (part), 1999)

If the permittee ceases work for any reason before the work is completed, all necessary steps shall be taken to leave the premises in a condition that will be safe and will not cause damage to adjoining properties or to the public roads or to any natural or artificial drainage facilities through erosion of materials, landslides, or other instability of slopes and materials.

(Ord. 118 § 1 (part), 1999)

The City Engineer shall issue a certificate of completion upon satisfactory completion of work under an approved permit.

A. The geotechnical engineer and/or engineering geologist certifies that all compaction requirements have been complied with and subdrains are located where shown on plans or plans are modified, as the case may be.

B. A licensed surveyor or registered civil engineer authorized to do survey work certifies that the horizontal and vertical controls conform to the plans or any approved changes to them.

C. The City Engineer is in receipt of a set of mylar plans which include all details of the grading operation and related details.

(Ord. 118 § 1 (part), 1999)

A. Adequate provisions shall be made to prevent any surface waters from damaging the cut face of an excavation or sloping surface of a fill. Retaining walls or cribbing constructed in accordance with the requirements of the City Engineer shall be used wherever necessary to prevent the surface of any excavation or fill from exceeding at any point the maximum allowable slopes set forth herein.

B. All site drainage shall be conveyed to the nearest adequate storm drain, natural watercourse, or street approved by the City Engineer as appropriate to deposit and receive such waters.

(Ord. 118 § 1 (part), 1999)

All persons performing any grading operations shall put into effect all safety precautions which are necessary in the opinion of the City Engineer and shall remove all loose dirt from the grading site and provide adequate anti-erosion and/or drainage devices, debris basins, or other safety devices to protect the life, limb, health, and welfare of private and public property of others from damage of any kind.

(Ord. 118 § 1 (part), 1999)

During grading operations the permittee shall be responsible for the prevention of damage to any public utilities or services. This responsibility applies within the limits of grading and along any routes of travel of equipment.

(Ord. 118 § 1 (part), 1999)

A. No excavation shall be made sufficiently close to the property line to endanger any adjoining public street, sidewalk, alley, or other public property or any adjoining private property without supporting and protecting such adjoining public or private property from settling, cracking or other damage in a manner approved by the City Engineer.

B. No person shall grade, whether or not a permit is required therefor under this Chapter, so that dirt, soil, rock, debris, or other material washed, eroded, or moved from the property by natural or artificial means creates a public nuisance or hazard, or an unlawful encroachment on private property or on a public road or street. Any such material deposited within the right-of-way of a public road or street which may constitute a nuisance or hazard to public traffic shall be removed immediately, and failure to do so on notice from the City authorizes the City to have the material removed at the expense of the permittee.

C. Whenever any portion of the work requires entry onto adjacent property for any reason, the permit applicant shall obtain the written consent of the adjacent property owner or their authorized representative, and shall file a copy of said consent with the City Engineer before a permit for such work may be issued.

(Ord. 118 § 1 (part), 1999)

See Section 9.04.120 for requirements of removal of groundcover.

(Ord. 118 § 1 (part), 1999)

No person shall obstruct, impede or interfere with the natural flow of storm waters, whether unconfined upon the surface of the land, within land depressions or natural drainage ways, within unimproved channels or watercourses, or within improved ditches, channels or conduits, except for construction operations permitted by the City.

(Ord. 118 § 1 (part), 1999)

No person shall perform any work or construct any facility (including excavation or embankment, trenching, driveway construction, or drainage facility) within the right-of-way of a public road or street, or within an easement under the jurisdiction of the City, without a permit from the City.

(Ord. 118 § 1 (part), 1999)

If, at any stage of grading, the City Engineer determines by inspection that the nature of the construction is such that further work as authorized by an existing permit is likely to endanger any property or public way, the City Engineer may require as a condition to allowing the work to be continued that such reasonable safety precautions be taken as he considers advisable to avoid such danger. Remedial actions may include but shall not be limited to specifying a flatter exposed slope, construction of additional drainage facilities, berms, terracing, compaction, cribbing, or retaining walls, or planting of slopes.

(Ord. 118 § 1 (part), 1999)

Whenever the City Engineer determines that any existing excavation or embankment or fill has become a hazard to life and limb, or endangers property, or adversely affects the safety, use, or stability of a public way or drainage channel, the owner of the property upon which the excavation or fill is located, or other person or agent in control of said property, upon receipt of notice in writing from the City Engineer shall within the period specified therein repair or eliminate such excavation or embankment so as to eliminate the hazard and be in conformance with the requirements of this Chapter.

(Ord. 118 § 1 (part), 1999)

It is the general intent of the regulations of this Chapter that site development design shall preserve to the extent that is reasonable and feasible the existing natural scenic value of hills and valleys and contours of land.

(Ord. 118 § 1 (part), 1999)

All site development work, whether or not a permit is required under this Chapter, shall be designed to:

A. Retain trees and other native vegetation which stabilizes steep hillsides, retains moisture, prevents or minimizes erosion, and enhances the natural scenic beauty, insofar as practical.

B. Place building pads in such a manner as to permit ample room for adequate landscaping and drainage between and around the buildings.

C. Minimize scars from cuts and fills and avoid permanent scarring of the hillsides.

D. Round off, in a natural manner, sharp angles at the top and toe of cut and fill slopes, and conform to existing terrain, both with respect to building sites and to road cross sections.

E. Limit development on steep or dangerous terrain.

F. Take into consideration geologic hazards and adverse soil conditions and their effect on the future stability of the development.

(Ord. 118 § 1 (part), 1999)

A. Maximum Slope.

1. Cuts shall not be steeper in slope than two (2) horizontal to one vertical unless the owner furnishes a soil or a geological report certifying that the site has been investigated and indicating that the proposed deviation will not endanger any public or private property or result in the deposition of debris on any public way or place or interfere with any existing drainage course.

2. The City Engineer may require the excavation to be made with a cut face flatter in slope than two (2) horizontal to one vertical if he finds it necessary for stability and safety.

B. Drainage Terraces. Cut slopes exceeding forty (40) feet in vertical height shall have drainage terraces not less than eight (8) feet in width, measured from the outer edge of the terrace to the invert of the drain, at vertical intervals not to exceed twenty-five (25) feet except that where only one such terrace is required it shall be located at mid-height. For cut slopes exceeding one hundred (100) feet in vertical height, the drainage terrace near mid-height shall be not less than twelve (12) feet in width. Design and construction of drainage terraces shall conform to the requirements of Section 9.04.455. All cut slopes shall be examined for evidence of seepage at completion of grading to determine if installation of horizontal drains is necessary.

C. Variations. Variations from the regulations in this Section may be allowed by the City Engineer if they will provide equivalent safety, stability, and protection against erosion, as recommended by a geotechnical engineer or engineering geologist.

(Ord. 118 § 1 (part), 1999)

A. Compaction. Except as otherwise provided in subsection (B) of this Section, all fills shall be compacted throughout their full extent to a minimum of ninety percent (90%) of maximum density as determined by the current ASTM D1 557 test method. Field density shall be determined by a method acceptable to the City Engineer. All existing on-site fills and backfills shall be excavated and stockpiled for reuse in planned fill areas.

B. Exceptions to Compaction Requirement.

1. Special Compaction. Compaction may be reduced to eighty-five percent (85%) of maximum density as determined by the specified test in subsection (A) of this Section within the outer eight (8) inches of fill slope surfaces when such compaction is provided by grid rolling or equivalent means.

2. Nonstructural Fills. Fills not intended to support structures, subdivision streets or improvements need not be compacted to the standard set forth in subsection (A) of this Section if the City Engineer determines that such compaction is unnecessary as a safety measure. In making this determination, the City Engineer may require that an investigation be made by an approved soil testing agency to establish the characteristics of the soil, the amount of settlement to expect and the susceptibility of the soil to erosion or slippage.

3. Planted Slopes. Slope surfaces may be prepared for planting by scarifying, by the addition of topsoil, or by other methods, if such loose material does not exceed a depth of three inches and said slopes otherwise comply with the requirements of this Section.

C. Preparation of Ground. The natural ground surface shall be pared to receive fill by removing vegetation, noncomplying fill, topsoil, and, where slopes are five (5) horizontal to one vertical or steeper, by benching into sound bedrock or other competent material. Five (5) feet of the lowermost bench shall be exposed beyond the toe of the fill. The bench shall be sloped for sheet overflow or a paved drain shall be provided.

D. Fill Slope. No compacted fill shall be made which creates an exposed surface steeper in slope than two (2) horizontal to one vertical. The City Engineer may require that the fill be constructed with an exposed surface flatter than two (2) horizontal to one vertical if he finds this necessary for stability and safety.

E. Fill Material. No organic or other reducible material shall be incorporated in fills. Except as recommended by the geotechnical engineer and approved by the City Engineer, no rock or similar irreducible material with a maximum dimension greater than four (4) inches shall be buried or placed within forty-eight (48) inches of finish grade. No expansive adobe soils shall be used in fills within five (5) feet of finish grade in street and building areas and shall not be placed in the slope area of high fills.

F. Drainage Terraces. Fill slopes exceeding thirty (30) feet in vertical height shall have drainage terraces not less than eight (8) feet in width, measured from the outer edge of the terrace to the invert of the drain, at vertical intervals not exceeding twenty-five (25) feet, except that where only one such terrace is required it shall be located at mid-height. For fill slopes exceeding one hundred (100) feet in vertical height, the drainage terrace near mid-height shall be not less than twelve (12) feet in width. Design and construction of drainage terraces shall conform to the requirements of Section 9.04.455.

G. Slopes to Receive Fill. Where fill is to be placed above the top of an existing or proposed cut or natural slope steeper than three (3) horizontal to one vertical, the toe of the fill shall be set back from the top edge of the slope a minimum distance of six (6) feet, measured horizontally, or such other distance as may be specifically recommended by a geotechnical engineer or engineering geologist and approved by the City Engineer. Fills shall not toe out on slopes steeper than three (3) horizontal to one vertical.

(Ord. 118 § 1 (part), 1999)

A. The property line of any proposed or existing site or parcel located within the grading project shall be located at the top of the slope or along any slope drainage terrace.

B. Excavation and fill slopes shall be set back a minimum of three (3) feet plus one-fifth the vertical height of the slope from the project boundary line, with a maximum of ten (10) feet.

C. Buildings and structures shall be set back from excavation or fill slopes a minimum of four (4) feet plus one-fifth of the vertical height of the slope, with a maximum of ten (10) feet.

Variations from the regulations in this Section may be allowed by the City Engineer if they will provide equivalent safety, stability, and protection against erosion, as recommended by a geotechnical engineer or engineering geologist.

(Ord. 118 § 1 (part), 1999)

A. General. Storm drainage structures, systems and facilities shall be provided as required by the City Engineer and in accordance with standard specifications on file with the City Engineer. In addition, storm drain structures, systems and facilities shall be in compliance with State and Federal National Pollution Discharge Elimination System (NPDES) requirements. In satisfaction of these requirements, the City Engineer may require the installation of grease traps, sediment basins, stormwater monitoring stations and such other devices and systems which the City Engineer determines are necessary for compliance with NPDES requirements. The design of all storm drainage structures, systems and facilities shall be in accordance with recognized principles of hydraulics. Such devices shall be considered components of the final erosion and sedimentation control plan.

B. Disposal. All drainage facilities shall be designed to carry surface waters to the nearest practical street, storm drain, or natural watercourses, approved by the City Engineer as appropriate to discharge such waters. If the drainage device discharges onto natural ground, rip-rap or a similar energy dissipater may be required. City standard curbs and gutters shall also be installed at the property line adjoining the public right-of-way for the purpose of conveying site runoff to storm drain facilities.

C. Site Drainage. Graded building sites (building pads) shall have a minimum slope of one percent towards a public street or drainage facility approved to receive stormwaters. A lesser slope may be approved by the City Engineer for sites graded in relatively flat terrain, or where special drainage provisions are made, when the City Engineer finds such modification will not result in unfavorable drainage conditions.

D. Terrace Drains.

1. All unlined swales or ditches on drainage terraces shall have a uniform longitudinal grade of not less than one percent nor more than three percent (3%) and a minimum depth of one foot at the deepest part. Such terraces shall drain into a paved gutter, pipe or approved watercourse adequate to convey the water to a safe disposal area.

2. The geotechnical engineer may approve steeper slopes based on sediment transport analysis.

3. The drainage terrace shall be provided with a lined ditch, if required by the geotechnical engineer for stability or prevention of erosion.

E. Overflow Protection. Berms, swales or other devices shall be provided at the top of cut or fill slopes to prevent surface water from flowing over or onto, and damaging the face of the slope. Special drainage provisions shall be made where a building or structure exists within five (5) feet of the top of a slope.

F. Maintenance of Drainage. The permittee shall maintain drainage facilities, in conformance with the requirements of this Chapter, during construction. The owner of the subdivided parcel shall maintain forever such drainage facilities as may be contained in a private storm drain easement.

G. Subdrains. Subdrains and laterals shall be as determined by the geotechnical engineer. Subdrain designs shall be approved by the City Engineer. Provisions shall be made for carrying off all collected water to suitable disposal points removed from all slopes.

H. Variations. Variations from the regulations of this Section may be allowed by the City Engineer if they will provide equivalent safety, stability, and protection against erosion and stormwater pollution as recommended by a geotechnical engineer or engineering geologist and by the County Flood Control District.

(Ord. 118 § 1 (part), 1999)

A. The surface of all erodible cut slopes more than five (5) feet in height and fill slopes more than three (3) feet in height shall be protected against erosion by planting with landscape materials as prescribed in Section 9.04.120. The plants and planting methods shall be suitable for the soil and climatic conditions of the site and in accordance with standard specifications on file with the City Engineer.

B. Irrigation System.

1. Planted slopes shall be provided with an approved system of irrigation. A functional test of the system may be required. For slopes less than twenty (20) feet in vertical height hose bibs may be allowed where a hose no longer than fifty (50) feet is necessary for irrigation.

2. The requirements for permanent irrigation systems may be modified, when approved by the City Engineer, because the type of plants selected, planting methods used, and soil and climatic conditions at the site make irrigation of the slope planting unnecessary.

C. Approval. The planting and irrigation system shall be installed after final grading. Final approval of the work and release of the bond shall be made when growth is established on the slopes.

D. Variations. Variations from the regulations of this Section may be allowed by the City Engineer if they will provide equivalent safety, stability, and protection against erosion, as recommended by a geotechnical engineer or engineering geologist.

(Ord. 118 § 1 (part), 1999)

A. Hours of Work. If operations under the permit are within five hundred (500) feet of residential or commercial occupancies, grading operations shall be limited to the hours between 8 a.m. and 5 p.m., Monday through Friday, or as approved by the City Engineer except that maintenance and service work on equipment may be performed at any time.

B. Encroachments on Public Rights-of-Way. Encroachment of operations on public rights-of-way without a valid encroachment permit is prohibited except for hauling of legal loads by vehicles permitted by law to operate on public roads.

C. Nuisances. Operations shall be controlled to prevent nuisances to public and private ownerships because of dust, drainage, removal of natural support of land and structures, encroachment, noise, and/or vibration.

(Ord. 118 § 1 (part), 1999)

A. Compliance With Plans and This Chapter. The permittee, his agent, contractor or employee, shall carry out the proposed work only in accordance with the approved plans and specifications and in compliance with all the requirements of this Chapter.

B. Notice of Work. In performing regular development work it shall be the responsibility of the permittee to notify the City Engineer at least one working day in advance so that the required inspections can be made.

(Ord. 118 § 1 (part), 1999)

The City Engineer may require the following reports, as cited in Section 9.04.350 and shall not finally approve any development or work until all required maps and reports have been submitted and approved:

A. A final report by the civil engineer certifying that all grading, lot drainage and drainage facilities have been completed and the slope planting installed in conformance with the approved plans and the requirements of this Chapter with a final contour map if the work is not in substantial conformity with the approved plans.

B. A report by the geotechnical engineer including the recommended soil-bearing capacity, a statement as to the expansive qualities of the soil, summaries of field and laboratory tests, and his opinion as to the adequacy of the work completed and its conformity with plans and specifications. The location of such tests and the limits of the compacted fill shall also show by plans and cross section the location of any subdrains, rock disposal areas and/or buttress fills in the work.

C. An engineering geologist's report based on the final contour map including specific approval of the grading as affected by geological factors. The report shall include a revised geologic map and cross sections, with recommendations regarding the location of buildings or sewage disposal systems.

(Ord. 118 § 1 (part), 1999)

The City Engineer may require the submission of a preliminary soil investigation report and/or engineering geological report before issuing a building permit for a structure to be placed on any fill or embankment constructed before the enactment of this Chapter, or excepted from the requirement for a grading permit, or on any other lot or parcel on which critically expansive soils, slide conditions, or other soils, or geologic hazards exist or may reasonably be anticipated to exist. If the City Engineer determines that the action recommended in this report is likely to prevent structural damage to the proposed structure, he shall recommend that the requirements contained in the report shall become a part of the required construction as a condition of the permit.

(Ord. 118 § 1 (part), 1999)

A. Any applicant or any permittee or his surety, if any, excepting to any condition imposed upon his grading permit, or to any denial thereof, or to the revocation or suspension thereof, may appeal in writing to the City Council by filing with the City Clerk a written notice of such appeal setting forth the specific grounds thereof.

B. Such notice must be filed within fourteen (14) days after notice of the action appealed from. The City Clerk shall thereupon set said matter for hearing before the Council and shall give written notice thereof separately to the appellant and his surety, if any. Said notice shall be given at least five (5) days before the hearing, and it shall be served personally or by deposit in the United States Mail in a sealed envelope, with postage fully prepaid, addressed to the permit holder and to his surety at the mailing address, or, if there is no mailing address, the business address, shown in the application or in the bond, as the case may be.

C. At such hearing the appellant shall show cause why the action excepted to should not be approved. Such hearing may, by the Council, be continued from time-to-time, and its findings on the appeal shall be final and conclusive in the matter.

(Ord. 118 § 1 (part), 1999)

The following shall constitute a public nuisance:

A. Any grading without a permit where same is required by this Chapter.

B. Any grading or other work done in violation of any of the conditions imposed thereon by a permit issued pursuant to this Chapter.

C. Any grading or other work which fails to be done as required by any conditions of a permit issued pursuant to this Chapter.

D. The existence of a hazardous condition as defined in Section 9.04.440 of this Chapter upon the determination by the City Engineer as provided in said Section that such condition exists.

(Ord. 118 § 1 (part), 1999)

The City Engineer or any other responsible officer of the City may summarily abate or cause to be abated any condition which is declared in Section 9.04.480 to be a public nuisance or may abate or cause to be abated any such public nuisance in any other manner established by statute, law, ordinance, rule, or regulation of the State of California or of the City, or may apply to a court of competent jurisdiction for appropriate relief, including but not limited to an order requiring or causing the abatement of any such public nuisance. The costs and expenses of such abatement shall become a lien upon the real property or premises upon which such public nuisance exists.

(Ord. 118 § 1 (part), 1999)

The procedure provided in this Chapter shall be cumulative and in addition to any other procedure or procedures provided in ordinances of this City or by State law for the abatement of any of the conditions described herein, and abatement hereunder shall not prejudice or affect any other action, civil or criminal, for the maintenance of any such condition.
