The development standards contained in this chapter are general in nature and apply to all zoning districts, unless otherwise indicated. These standards are provided as minimum or maximum standards and may be modified by more stringent standards in particular districts and/or due to specific situations. The primary intent of this chapter is to provide generally acceptable standards of development for Chino Hills.

(Ord. 68 § 9.10.010, 1995)

All properties within the City shall be kept and maintained in a clean, neat, orderly, operable, and usable condition. This requirement applies to buildings, paving, fences, walls, landscaping, water, earth, and any other structures or natural features.

(Ord. 68 § 9.10.020, 1995)

Neither the provisions of this Development Code nor the granting of any permit provided for in this Development Code shall authorize or legalize the creation or maintenance of any public or private nuisance.

(Ord. 68 § 9.10.030, 1995)

A.

Single-Family Residential Properties. Occasionally, a lot is adjacent to more than one street. In such cases, the following requirements shall be observed in identifying the front lot line. Figure 10-1 illustrates the following provisions:

1.

When a lot exists between two developed lots which both abut the same street, the front lot line shall be on the same street as the existing developed lots on either side.

2.

When a lot is adjacent to vacant lots or developed lots which abut either street, the following criteria shall apply:

a.

Where one street is of a higher classification than the other, the lot line fronting the street with the lower classification shall be the front lot line.

b.

If the lot in question is a corner lot and both streets are of the same classification, the narrower of the two frontages shall be designated the front lot line.

c.

The Director of Community Development shall make the determination when the above criteria cannot be precisely applied to the particular situation as a result of topography or other factors by effectuating the intent of these criteria as much as possible.

3.

The front lot line for a corner lot or a reverse corner lot is the lot line which fronts the street with the lower classification. If both streets are of the same classification, the narrower of the two frontages shall be designated the front lot line, except in those cases where the subdivision or parcel map specifies another line as the front lot line.

4.

The front lot line for a cul-de-sac lot is that lot line which abuts the cul-de-sac street.

B.

Multi-Family Residential and Nonresidential Properties. For a multi-family residential or nonresidential property with multiple street frontages, the following requirements shall be observed in identifying the front lot line:

1.

Where one street is of a higher classification than the other, the lot line fronting the street with the higher classification shall be the front lot line.

2.

If the streets are of the same classification, the widest of the frontages shall be designated the front lot line.

3.

The Director of Community Development shall make the determination when the above criteria cannot be precisely applied to the particular situation as a result of topography or other factors by effectuating the intent of these criteria as much as possible.

(Ord. 68 § 9.10.040, 1995)

(Ord. No. 265, § 2(d), 8-27-2013)

A.

Through Lots. Both frontages of a through lot shall have a minimum setback from both streets of twenty (20) feet, unless the provisions of this Development Code allow for reduced non-garage and rear setbacks for shallow lots.

B.

Key Lots. The depth of the required front yard of a key lot shall not be less than the average depth of the street-abutting yards of the adjoining interior and reversed corner lots. The garage portion of the primary structure shall require a minimum front yard setback of not less than twenty (20) feet.

(Ord. 68 § 9.10.050, 1995)

A.

Area.

1.

If a portion of a lot or parcel of land is acquired by any means, including dedication, purchase, or condemnation for any public use including recreation, services, or utilities, that lot or parcel shall be considered conforming as long as the area is reduced to no less than ninety (90) percent of the minimum required area for the zoning district in which the lot or parcel is located.

2.

The Planning Commission shall have the authority to reduce the ninety (90) percent minimum required area pursuant to all the conditions and procedures relating to minor variances found in Chapter 16.72 of this development code.

B.

Width. If a portion of a lot or parcel is acquired by any means, including dedication, purchase, or condemnation for any public use which may include recreation, services, or utilities, that lot or parcel shall be considered conforming as long as the width is not reduced by more than thirty (30) percent. In no case, however, shall a lot less than forty (40) feet in width be considered conforming.

C.

Building Setbacks and Lot Coverage. If a portion of a lot or parcel is acquired by any means, including dedication, purchase, or condemnation for any public use which may include recreation, services, or utilities, that lot or parcel and any structures located on that lot or parcel that were legally permitted when constructed shall be considered conforming as to setback and lot coverage requirements. In the instance where the setback has been reduced, subsequent improvements to that lot or parcel adjacent to the acquired property shall be permitted to adhere to the reduced setback in existence on the day of the public use acquisition. In the instance where the maximum lot coverage has been increased over that permitted in Chapter 16.10.30 of this development code by the reduction in lot size by the public acquisition, subsequent improvements to the lot or parcel shall not increase lot coverage by more than five (5) percent beyond the lot coverage in existence upon the day of the public use acquisition.

(Ord. 68 § 9.10.060, 1995)

(Ord. No. 273, § 3(b), 7-22-2014)

D.

Agreement to Improve.

1.

In lieu of the required improvements and if in the best interest of the City, the City Council may accept from any responsible party an agreement to make the specified improvements within a specified time period.

2.

Such agreements shall be accompanied by security deposits which may include cash, negotiable bonds, or savings and loan certificates, letters of credit, or other security as authorized by the City Engineer. The security deposit shall equal the cost of the agreed upon improvements. Where savings and loan certificates or deposits are deposited, the owners thereof shall assign the certificates to the City and administration adjusted for inflation as determined by the City Engineer. Such deposit and assignment shall be subject to and in compliance with the provisions and conditions of the municipal Development Code of the City.

3.

If the estimated cost of the improvements equals or exceeds one thousand dollars ($1,000.00) the applicant may file a corporate surety bond with the City in lieu of the deposit. Such corporate surety bond shall guarantee the adequate completion of all of the improvements in a penal sum equal to the estimated cost.

4.

In cases where the stipulated time within which improvements were to be made expires, the City Council may grant additional time as it considers appropriate. Granting of additional time shall include recalculation of improvement costs and security deposits. The extension must be granted prior to expiration of the time limit.

5.

Should the responsible person fail to complete any improvement within the agreed upon time, the City Council may determine that the agreed upon improvement is incomplete and may cause a portion of the deposit or surety bond to be forfeited to the City to complete or correct the work. Such forfeiture shall not exceed the amount required to complete the agreed upon work and expenses incurred by the City as a result of the default. Not less than ten (10) days prior to such a determination, the City shall serve the person with written notice. If the written notice is delivered by mail, it must be sent by certified mail and shall be served not less than twenty (20) days prior to the determination. If after ten (10) days the City has not received the return receipt or the letter is returned to the City "refused," the notice shall be sent by regular first class U.S. mail and a declaration of mailing completed and filed.

E.

Adequate Rights-of-Way. The City Council may grant a modification to the provisions of this section, thereby relieving the applicant from compliance with all or a portion of the provisions of this section, subject to the following findings:

1.

That relieving or partially relieving the applicant's development from providing the required dedications and improvements is consistent with the General Plan and the best interest of the City; and

2.

The required improvements are included in a budgeted City project which will be complete prior to the start of the applicant's development or within an approved assessment district and the improvement can be more effectively provided by the City; or

3.

The required construction would create a temporary drainage or traffic problem that can be avoided by delaying the improvement to a later date as part of comprehensive improvements to the area; or

4.

The City Engineer determines current improvements to be satisfactory.

All requests for modifications shall be made in the form of a major Variance application, as specified in Chapter 16.70.

One of the following measures or combinations of such measures may be used to mitigate the effect of creating culs-de-sac up to six hundred (600) feet in length.

i.

Limitation of the total number of dwelling units which have access to the cul-de-sac to no more than fifteen (15), and restriction of further subdivision of parcels and construction of additional independent residential units which have access to the cul-de-sac. Such restrictions shall be imposed through the conditions of approval of the development project or other method as approved by the Community Development Director.

ii.

A continuous perimeter access road at least twenty (20) feet in width is provided along the portion of the cul-de-sac exposed to fuel-modified areas such that it is drivable under normal conditions by firefighting vehicles, provides adequate maneuvering space for such vehicles, and is designed such that at least one point of access to the perimeter access road is taken from roads other than the cul-de-sac in question.

c.

For public streets, the cul-de-sac road shall have a minimum forty (40) foot wide paved surface. There shall be at least one area approximately at the midpoint of the cul-de-sac that serves the same function of a cul-de-sac bulb in allowing firefighting vehicles adequate room to turn around. For private streets, the cul-de-sac road may have a minimum twenty-six (26) foot wide paved surface, provided no parking is allowed on the street.
