§ 10-2.401 Purpose.

It is the purpose of this article to minimize erosion, soil compaction, topsoil displacement, siltation of water courses, and other adverse effects of grading, including alteration of the scenic qualities of the natural terrain. It is also the purpose of this article to insure that at the completion of the project, the visible alteration of the natural terrain be minimized.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.402 Compliance required.

All grading and grading operations shall comply with the requirements of this chapter and the Town's Standard Specifications. All plans for grading shall be approved by the City Engineer.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.403 Hours of operation.

All grading operations shall be carried on between the hours of 8:00 a.m. and 5:30 p.m., Monday through Friday, unless the City Engineer finds evidence that an emergency exists that imperils the public safety, in which event(s) he or she may direct the work to proceed during such other hours as may be necessary for the duration of the emergency. No grading operations shall be carried on any day designated by resolution of the City Council to be recognized and celebrated as a public holiday by the employees of the Town of Los Altos Hills.
(§ 15, Ord. 299, eff. December 11, 1985; § 3, Ord. 318, eff. January 18, 1988)

§ 10-2.404 Restrictions during wet season.

The City Engineer may restrict grading operations during the wet season. The wet season is defined as the period between October 1st and April 30th. The City Engineer may allow grading to proceed during the wet season if precipitation has been minimal; if the grading technique to be used will minimize the risk of landslides, erosion, or damage to adjacent properties or environmentally sensitive areas from soil movement; or if it is in the interest of public health and safety to permit grading. Following any 24 hour period during the year in which one-half inch or more of rain has fallen the City Engineer may prohibit grading.
(§ 15, Ord. 299, eff. December 11, 1985; § 1, Ord. 569, eff. May 20, 2017; Ord. 612, eff. 7/20/2024)

§ 10-2.405 Dust and dirt control.

All graded surfaces shall be wetted or suitably contained to prevent nuisances from dust or spillage on Town streets or adjacent properties. Equipment, materials, and roadways on the site shall be used or treated in a manner so as to prevent excessive dust conditions.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.406 Slopes.

The maximum slope of any fill shall not exceed two horizontal to one vertical. The maximum slope of any cut shall not exceed one and one-half (1.5) horizontal to one vertical. A steeper slope may be created only if approved by the City Engineer. Where cohesionless or expansive soils are used, or where other conditions warrant a further restriction of the slope, the City Engineer may impose such restriction.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.407 Property lines.

No grading shall be permitted within 10 feet of any property line and public or private road right-of-way easement, except as required for construction of pathways, to allow access for driveways where they cross a property line, or within a panhandle.
(§ 15, Ord. 299, eff. December 11, 1985; § 1, Ord. 557, eff. February 15, 2015)

§ 10-2.408 Cuts and fills.

All cuts and fills shall be rounded to natural contours. Finished grades shall conform to the natural grade as much as possible and shall not contain sharp angles or other unnatural features.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.409 Erosion control.

All cut and fill surfaces created by grading and subject to erosion shall be planted with a ground cover compatible with the natural ground covers in the Town and which will thrive with little or no maintenance once established. Topsoil shall be stockpiled during rough grading and used on cut and fill slopes. On slopes likely to be extensively disturbed by later construction, an interim ground cover shall be planted or other acceptable erosion control device shall be used.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.410 Safety precautions.

(a) 
Natural Hazards. If, at any stage of the grading, the City Engineer determines by inspection that the nature of the formation is such that further work as authorized by an existing permit is likely to imperil any property, public way, water course, or drainage structure, the City Engineer may require, as a condition to allowing the work to continue, that such reasonable safety precautions be taken as he or she considers advisable to avoid the likelihood of such peril. Such safety precautions may include, but shall not be limited to, specifying a flatter exposed slope, the construction of additional drainage facilities, berms, terracing compaction or cribbing, the installation of plant materials for erosion control, and reports of a soils engineer and/or an engineering geologist whose recommendations may be made requirements for further work.
(b) 
Storm Hazards. Where it appears that erosion damage may result from a storm because the grading is not complete, work may be stopped and the permittee may be required to install temporary plantings to control erosion, install temporary structures, or take such other measures as may be required to protect adjoining property or the public safety. On large operations or where unusual site conditions prevail, the City Engineer may specify the time to begin the grading and the time of completion of the grading, or he or she may require that the operation be conducted in specific stages so as to insure the completion of protective measures or devices prior to the advent of seasonal rains.
(§ 1, Ord. 299, eff. December 11, 1985)

§ 10-2.501 Purpose.

The purposes of this article are to preserve the regional drainage patterns and natural swales without modification insofar as is feasible; to insure that artificial drainage systems, when they are necessary, be of an inconspicuous design; and to minimize erosion and sedimentation by using vegetative ground covers wherever they are a practical substitute for engineering structures.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.502 Drainage standards.

Drainage systems shall be designed to minimize the effects of erosion, situation, and flooding on immediate or distant downstream neighbors. They shall follow regional patterns and use natural swales wherever possible.
Provisions shall be made to prevent surface waters from damaging the cut face of an excavation or any portion of a fill. All drainage ways and structures shall carry surface waters to the nearest practical street, storm drain, or natural watercourse approved by the City Engineer as a safe place to receive such waters. The City Engineer may require drainage structures to be constructed or installed as necessary to prevent erosion damage or to prevent the saturation of the fill or material behind cut slopes. Drainage facilities and impervious surfaces shall be designed to prevent adjacent properties from receiving run-off from a project site, except through approved drainage channels. Drainage facilities shall be constructed according to standard specifications developed by the City Engineer.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.503 Drainage facilities standards.

The City Engineer shall consider the following in making recommendations to the Site Development Authority regarding the adequacy of proposed drainage facilities:
(a) 
The design and location of any terraces in cut and fill slopes, including the distance between terraces, the gradient of any swales or ditches in the terraces, and the tributary area from which water is discharged into a swale or ditch.
(b) 
The capacity of proposed subsurface drainage on cut and fill slopes to carry run-off from the site, based on the amount of impervious surfaces, the absorption characteristics of the soil, the proposed discharge point of subsurface drainage, and effects of vegetative cover in absorbing water.
(c) 
The location(s) and type(s) of devices, such as downdrains, used to prevent erosion in the area of discharge.
(d) 
The extent to which proposed drainage facilities prevent standing water or other localized conditions of soil saturation on a site.
(e) 
The extent to which proposed drainage facilities decrease the velocity and concentration of water runoff to reduce the potential for soil erosion.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.504 Drainage easements.

Whenever a site development permit is requested for an activity which may affect natural drainage patterns or rates, the Planning Director or Planning Commission may, upon recommendation of the City Engineer, require the dedication of an easement sufficient to accommodate natural or installed drainage systems.
(§ 15, Ord. 299, eff. December 11, 1985; § 5, Ord. 384, eff. October 18, 1996)

§ 10-2.601 Purposes.

The purposes of this article are to insure that provision is made for public pathways to provide pedestrian, equestrian, and bicycle access for Town residents; to implement the Master Pathway Plan of the General Plan of the Town of Los Altos Hills; and to prevent damage to the Town's pathways from activities that occur on private property.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.602 General policies.

(a) 
Each property shall have direct access to a pathway or indirect access via a vehicular right-of-way.
(b) 
Undeveloped properties along designated pathways and bicycle routes may be required to dedicate an easement for the extension of the pathway as a condition of site development approval.
(c) 
Pathways shall be sited and improved in a manner that creates minimal disturbance to the natural environment.
(d) 
Equestrian and pedestrian paths should generally be separated from roadways.
(e) 
Pathways shall be of sufficient width to provide a safe corridor for travel and pathway maintenance.
(f) 
Except for designated regional trails and bikeways, paths shall be designed primarily for local use by Town residents.
(g) 
Intersections of paths and vehicular rights-of-way shall be kept clear of vegetation which might obscure the view of users.
(h) 
Pathways shall be designed and maintained to prevent erosion, to prevent injury from landslides or other soil movements, and to assure proper drainage of the path.
(i) 
Slopes in excess of 15% adjacent to a pathway shall contain soil retentive landscaping, rockery, netting, or other devices approved by the City Engineer to reduce potential damage to the path or injury to users of the path from landslide, soil creep, or erosion.
(j) 
Pathways shall be designed and maintained to minimize their impact on adjacent properties.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.603 Construction activities near pathways.

Construction activities and tilling undertaken near a pathway shall create minimal disturbance to the pathway. Appropriate measures shall be undertaken to assure that landslides or soil movement do not occur on pathways. Temporary drainage facilities or plantings may be required by the City Engineer during construction to insure that pathways are not eroded or damaged from stormwater runoff. Any damage to a pathway resulting from private activities shall be repaired by the responsible party at their expense. In the event damage creates an irreparable break in the pathway, the responsible party may be required by the Town to provide or acquire an alternate easement for the pathway.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.604 Drainage.

Drainage facilities on private properties adjoining pathways shall be designed and maintained so that stormwater runoff from those properties does not drain onto the pathways.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.605 Driveway surfaces.

The surfacing or resurfacing of a driveway at its intersection with a path shall be accomplished with material and methods acceptable to the City Engineer to reduce the danger of slipping by users of the pathway.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.606 Payment of pathway fees and/or dedication of pathway easements.

Whenever a site development permit is requested for a main residence, an accessory dwelling unit, an addition to a structure of at least 900 square feet of "habitable" floor area (including cumulative additions of 900 or more square feet of habitable floor area made over a period of 10 year(s)), or a barn or stable for equestrian use of at least 900 square feet in floor area, on a property which is designated on the Master Path Plan for an off-road pathway or for a roadside pathway, but where all or a portion of such roadside path cannot feasibly be located within the existing public or private right-of-way, the Site Development Authority may require the payment of pathway fees and/or dedication of an easement for public use as part of the Town's pathway system according to the guidelines contained in the Pathway Element of the General Plan. Pathway easements shall be required within emergency road easements. In addition, the following guidelines apply:
(a) 
An easement should generally be located along the boundary of a property;
(b) 
The easement shall be located so as to connect to existing or future pathway segments at the boundaries of a property; and
(c) 
The easement shall not be located on terrain that cannot be safely or conveniently traversed by pedestrians or equestrians.
(§ 15, Ord. 299, eff. December 11, 1985; § 4, Ord. 381, eff. April 19, 1996; § 1, Ord. 584, eff. November 16, 2019)

§ 10-2.608 Pathway fee.

A site development permit for a lot on which no path is needed and on which is to be constructed a main residence, an accessory dwelling unit, an addition to a structure of at least 900 square feet of "habitable" floor area (including cumulative additions of 900 or more square feet of habitable floor area), or a barn or stable for equestrian use of at least 900 square feet in floor area shall be assessed a pathway fee, the amount of which shall be fixed by Council resolution as a development impact fee pursuant to the Mitigation Fee Act (AB 1600) (Government Code Section 66000 et seq.). For purposes of assessing the pathway fee, "habitable" floor area does not include additions for kitchen and dining rooms, entryways, foyers, hallways, stairways, or elevators. Pathway fees collected shall be deposited in the Town's pathway fund. No fee shall be assessed if the lot has been assessed and has paid a fee pursuant to Section 9-1.1112 of the Subdivision Ordinance.
(§ 6, Ord. 381, eff. April 19, 1996; § 1, Ord. 584, eff. November 16, 2019)

§ 10-2.701 Purposes.

The purposes of this article are to insure that the site, location and configuration of structures are unobtrusive when viewed from off-site; that scenic views are retained; that buildings do not dominate the natural landscape; that ridgelines and hilltops are preserved; and that the siting of structures is consistent with other provisions of this chapter concerning grading, drainage, and erosion control.
(§ 15, Ord. 299, eff. December 11, 1985)

§ 10-2.702 Siting.

(a) 
Alternative Locations. The location of buildings and structures shall be selected so as to minimize runoff from the site, the volume of off-site drainage created, the destruction or alteration of natural vegetation, and the impairment of scenic views from off the site.
(b) 
Preservation of Ridgelines, and Hilltops. Ridgelines and hilltops shall be preserved by the siting of structures to take advantage of natural topographic or landscape features which would cause structures to blend with their natural surroundings. The Site Development Authority shall consider the following guidelines in approving the location of a structure:
(1) 
Single story buildings and height restrictions may be required on hilltops and ridgelines.
(2) 
Cut foundations should be used in place of fill on hilly terrain.
(3) 
Native or naturalized vegetation should be used to conceal structures wherever possible.
(4) 
Structures may be located on ridgelines or hilltops only when they can be rendered unobtrusive by one or more of the following techniques:
(i) 
The use of natural vegetation and/or added landscaping;
(ii) 
The use of a low-profile house, with a sloping roofline and foundation, that follows the natural contours of the site;
(iii) 
The use of exterior roofing and siding materials and colors that blend with the natural landscape.
(5) 
Hilltops or ridgelines shall not be cut down, flattened, or similarly graded to create a building pad in excess of the actual area covered by the principal residence.
(c) 
Disturbance to the Site. The location of all structures should create as little disturbance as possible to the natural landscape. The amount of grading, excavation, or fill shall be the minimum necessary to accommodate proposed structures, unless grading is proposed to lower the profile of buildings. Additional grading may be allowed for the purpose of lowering the profile of the building provided that at the completion of the project the visual alteration of the natural terrain is minimized. The removal of vegetation and alteration of drainage patterns shall be the minimum necessary to accommodate the proposed structure.
(d) 
Passive Solar Energy Conservation. Opportunities for passive solar energy shall be considered in the siting of buildings.
(e) 
Creek Protection. Structures shall be set back a minimum of 25 feet from the top of bank of all creeks. Greater setbacks may be required along major creeks in the Town; however, lesser setbacks may be allowed where approved by the Planning Commission. Improvements required to all creeks shall be accomplished to appear natural and to maintain the natural meandering course of the existing creek. Creeks and banks shall be protected so as to remain in their natural state as much as possible. They should not be disturbed by the building or grading process. No grading shall be allowed in creeks or within the required setbacks from top of bank. Siting of structures shall be done with safety as a primary concern. Safety concerns and preservation of riparian habitat are required to be simultaneously addressed when designing development and required improvements to creeks.
(§ 15, Ord. 299, eff. December 11, 1985; §§ 6, 7, Ord. 370, eff. May 20, 1994; § 1, Ord. 504, eff. October 28, 2006)

§ 10-2.703 Construction.

(a) 
Foundations. The types of foundation to be used for primary and accessory structures shall be selected to ensure that at the completion of the project the visual alteration of the natural terrain is minimized. Type II foundations—step-on-contour, daylight, pole foundations, or a combination thereof — shall be used on building sites with natural slopes in excess of 14%.
(b) 
Color and Materials. For large or highly visible surfaces on buildings, special attention shall be given to the selection of exterior colors and construction materials that are not highly reflective.
(c) 
Appurtenances. Dish antennae, freestanding solar panels, and similar appurtenances as defined in Section 10-2.301 may be approved by the Planning Director under the following conditions:
(1) 
The appurtenance is the minimum size necessary to adequately serve its purpose.
(2) 
The appurtenance can be suitably screened by landscaping, the use of colors or materials that blend with their surroundings, or by natural features of the site without adversely affecting its operation.
(3) 
Landscaping shall be placed to screen appurtenances such as solar panels and dish antennae in such a manner as to not significantly affect the basic function of such equipment. These structures shall not be permitted unless they can function in the presence of such screening.
(4) 
The appurtenance is not placed in a conspicuous position or on a hilltop or ridgeline.
The Planning Director may impose additional conditions on the size, location, and construction of appurtenances as the Planning Director deems necessary to carry out the purposes of this chapter.
(§ 6, Ord. 384, eff. October 18, 1996)

§ 10-2.801 Purpose.

The purposes of this article are to create the maximum compatibility of development with the natural environment; to preserve the rural qualities of the Town, to insure that structures, as viewed from off-site, blend harmoniously with the natural landscape and are unobtrusive; to maintain soil stability, to abate noises; to protect wildlife habitats; to retain aesthetic quality; to conserve water resources; and to protect properties against fire and other natural forces.
(§ 15, Ord. 299, eff. December 11, 1985; § 1, Ord. 520, eff. October 16, 2010)

§ 10-2.802 Landscape policies.

(a) 
Erosion. Landscaping shall be required to control erosion, retard soil creep, and reduce the potential for landslides.
(b) 
Noise. Landscaping and berms may be required to shield Town residents from unnatural noises, such as those from freeways, arterial streets, and nonresidential land uses.
(c) 
Visual Effects. Landscaping shall be required to mitigate the visual effects of development from off the site.
(d) 
Preferred Plants. Landscaping should utilize fire retardant species. Native or naturalized plants or other plant species that blend naturally with the landscape should generally be favored.
(e) 
Maintenance. Landscaping shall be maintained in healthy condition by property owners and shall not intrude into easements, paths, or the lines-of-site required at intersections and along roads.
(f) 
Tree Preservation. Every feasible attempt should be made to preserve existing trees except those trees identified in the Los Altos Hills Landscape Guidelines invasive plant list.
(g) 
Eucalyptus Trees.

Where:
PWB = Parcel water budget (units per year)
Slope = Average slope of the parcel or lot as a percentage of 1.0 to the nearest hundredth
0.8 = Water conservation factor
43.0 = Reference evapotranspiration (ETo) in Los Altos Hills, in inches/year
0.62 = Conversion factor (to gallons)
0.55 = ET adjustment factor (ETAF)
An = Net lot area (square feet)
MDA = Maximum development area. The maximum development area (in square feet) allowed for the property.
0.45 = Additional water allowance for SLA
SLA = Special landscape area (square feet)
748 = Number of gallons in a unit (100 cubic feet) of water
120 = Number of units for indoor water use per property per year, or as may be modified by the Planning Director upon a demonstration of difficulty or unnecessary hardship pursuant to subsection (v). Note: Not applicable if a landscape/outdoor use meter is installed.
Example PWB calculation: one-acre (43,560 sq. ft.) lot with 14% slope and 12,339 sq. ft. of MDA and no special landscape area:
PWB = [(1.0-.14)(0.8)(43.0)(0.62)[0.55 x (43,560 - 12,339) + (0.45 x 0)] / 748] + 120 = 541 units/year
