PDF version 





11-7-1:  APPLICABILITY(2534)  Any Official Development Plan or Final Plat for the development of any property within any zoning district other than Planned Unit Development shall be in substantial compliance with the standards set forth in this Chapter.  For Planned Unit Developments, these standards shall be used as guidelines and may, at the option of the City, be required.  These standards are in addition to all other standards, guidelines, policies and City Code requirements otherwise applicable to land use and development within the City.  In the case of a conflict between these standards and another standard, guideline, policy or requirement, the more restrictive standard, guideline, policy or requirement shall apply. 

11-7-2:  LOT AND BLOCK STANDARDS:  (2534 3774)

(A)  The lengths, widths, and shapes of blocks shall be determined with due regard to:

  1. Topography.
  2. Convenient and safe access and circulation including access and circulation, for emergency and service vehicles.
  3. Applicable regulations regarding lot sizes and dimensions.
  4. Provision of adequate building sites suitable to the special needs of the type of use contemplated.
  5. Availability, location, and capacity of utility service and utility system design and capacity.

(B)  The width, depth, shape, and orientation of lots shall be designed for the type of use contemplated.  As a minimum, all lots shall conform to the following standards: 

  1. No lots shall be platted in areas subject to flooding except in conformance with this Code.
  2. All lots shall front on a public street or highway or private street with easements guaranteeing public access.
  3. Depth and width of lots shall be adequate to provide the necessary private service and parking facilities required by the type of use and development contemplated.
  4. Lots shall be designed to provide positive drainage away from all buildings, and individual lot drainage shall be coordinated with the general storm drainage pattern for the area.
  5. Corner lots shall generally be adequate in size to compensate for two street frontages and to satisfy vehicular sight triangle standards.
  6. Wherever possible, side lot lines shall be at right angles to the street line or at right angles to the tangent to the curve of the street line.
  7. Subdivision lots and streets shall be oriented in a manner to ensure location of structures and landscaping in the most energy efficient manner.

11-7-4:  OFF-STREET PARKING STANDARDS(2534 2678 3084 3774)


        (1)  The Council hereby finds, determines and declares that it serves the interest of the public to: 
                (a)     Lessen congestion upon the public streets of the City;  
                (b)     Provide adequate off-street parking that balances parking demand with the need for multiple modes of travel’
                (c)     Recognize the parking efficiencies gained through mixed-use development and development proximate to rail and bus transit and their impact on parking demand;
                (d)     Encourage adequate parking for land uses in Westminster without creating excess vacant parking, and
                (e)     Promote bicycle use by providing safe and convenient bicycle parking through minimum requirements for bicycle parking facility type and amount.

          The regulations stated herein are in furtherance of these purposes by requiring the owners and operators of land, structures and uses to provide parking on their own premises and off the public streets for their employees, customers, tenants, clients, patients and other visitors.  Nothing in these regulations shall be deemed to deprive such owners or operators of the right to maintain control over all such land devoted to off-street parking space or to make whatever charges to persons making use thereof as they may deem appropriate.

        (2)     For land, structures or uses actually used, occupied or operated on or before the respective effective date of this section, there shall be provided such off-street parking space as was required for such land, structures or uses by any previous ordinance, or development plan approval, except that, if any previous ordinance or approval required more off-street parking for land, structures or uses than is required under this section, then there need be provided only such off-street parking as is required in this Title.  If such land, structures or uses are enlarged, extended, or changed, there shall be provided for the increment only at least the amount of off-street parking space that would be required hereunder if the increment were a separate land, structure or use established or placed into operation after the effective date of this section.

        (3)     For all uses established or placed into operation after the effective date of this section, there shall be provided at least the amount of off-street parking hereinafter set forth.

        (4)     Bicycle parking facilities shall be provided for any new building constructed, any new use established, any addition or enlargement of an existing building or use, for any change in the occupancy of any building, or change of use conducted. The number of bicycle parking spaces shall comply with the provisions in subsection (E)(2) of this Section.  The design and maintenance of bicycle storage facilities shall conform to the standards in subsection (E)(1) of this Section. 

        (5)     Handicapped parking facilities shall be provided for any new building constructed, any new use established, any addition or enlargement of an existing building or use, for any change in the occupancy of any building, or for change of the use conducted.  The number of handicapped parking spaces shall comply with the provisions in subsection (D)(2) of this Section.  The design and maintenance
of handicapped parking spaces shall conform to the standards set forth in subsection (D)(1) of this Section. 

        (6)     These off-street parking regulations shall apply to all development in Westminster, including those areas included in the Westminster Urban Renewal Plan, as well as other locations with adopted Specific Area Plans.  If off-street parking requirements are not included in a Specific Area Plan, the regulations in this section shall control. 

        (7)  The zoning for the property on which the required parking facilities are to be provided must be the same as for the building served.

        (8)  Separate off street parking space shall be provided for each use; or the parking space required of two (2) or more uses located on the same zone lot may be combined and used jointly; provided, however,

(a)  Where off street parking space is combined and used jointly by two (2) or more uses having different standards for determining the amount of off street parking space required, the parking space shall be adequate in area to provide the sum total of off street parking space requirement of all such uses.

(b)  Where off street parking space is combined and used jointly by two (2) or more uses having the same standard for determining the amount of off street parking space required, all of such uses, for the purpose of this section, shall be considered a single unit and the gross floor area of all such uses in all structures on the same zone lot or the number of employees of all such uses in all structures on the same zone lot as fixed by the applicable standard, shall be taken as a single total for the purposes of determining the amount of off street parking space required.

(c)  Where it can be demonstrated, by an applicable parking study, that combining the parking areas of two (2) or more uses will reduce the need for parking spaces, the Planning Manager may authorize a shared parking agreement thus reducing the total number of spaces required.  In no event shall the said reduction be more than twenty percent (20%) of the total that will otherwise be required.

       (9)       Deferred Parking

(a)        To avoid requiring more parking spaces than are actually needed to serve a development, the Planning Manager may defer the provision of a portion of the required parking, if a deferred parking area is created in the Official Development Plan.  Said deferred parking area shall be landscaped but shall not be included in the total landscaped area for the purpose of calculating landscaping requirements.  The deferred area shall be designed so that if parking is constructed at a future time in the area, it will meet all of the provisions of the commercial design guidelines and landscape regulations.

(b)   The developer shall enter into a written agreement with the City committing to the construction of paved parking in the deferred area at such time as the Planning Manager determines, at his/her discretion that additional parking is required.  The Planning Manager shall notifiy the property owner in writing that additional parking is required, after which the owner shall complete the improvements within six (6) months of notification.

       6.  The land area for which grading is proposed is:

(a) part of a pending application before the City for approval of a rezoning, Official Development Plan, or Preliminary Development Plan; or
(b) located within a subdivision that is under current development, or which is reasonably expected to be developed in the course of the build-out of the subdivision and the City Manager determines that the City's approval of a land disturbance permit for the property should be deferred until the final plans for the property are submitted for City review and approval in order to protect the public's interest in providing input concerning the future development of the property in advance of the normal review and approval process. 


       1.  The City Engineer, through periodic inspections, shall be responsible for determining whether the erosion and sediment control work accomplished by the applicant is in conformance with the applicant's approved erosion and sediment control plan.

       2.  The City Engineer may prohibit further work to be done on the applicant's site if he determines that the work does not comply with the approved erosion control plan.  Such work may be stopped until measures in the approved erosion control plan are completed.  The City Engineer may require remedial work to be done to protect completed work, prevent damage, or repair damage.

       3.  Upon receipt of written request by the applicant, the City Engineer shall give the applicant a certificate of completion indicating the date the measures in the approved plan were completed.


       1.  The City hereby declares that it shall be a nuisance for any property owner to permit an unreasonable amount of dust or soil runoff to be transported from the land of the property owner to any downhill, downwind or any other nearby property, any public or private waterway, or any street, storm drainage or other public utility system.  Such nuisance may be abated pursuant to the provisions of Chapter 4 of Title 8 of this Code.  

       2.  In addition to any nuisance abatement action the City may pursue pursuant to Chapter 4 of Title 8 of this Code, the City, through its City Engineer, may order any owner of property from which fugitive soil is being exported in contravention of the provisions of this section 11-7-7 to submit a soil erosion/dust control plan meeting the requirements of this section and satisfactory to the City Engineer within a specified time period.  The failure of any property owner to submit such a soil erosion/dust control plan as ordered shall be deemed to constitute a separate violation of the City Code punishable pursuant to the civil penalty provision set forth in section 1-8-1 of this Code. 

       3.  Upon the approval of a soil erosion/dust control plan submitted pursuant to this section 11-7-7(G), any failure by the property owner to implement, install, perform or maintain such soil erosion and sediment control measures in accordance with the approved soil erosion/dust control plan shall also constitute a violation of this Code punishable pursuant to the civil penalty provisions of section 1-8-1 of this Code. 

       4.  Where probable cause exists to believe that a violation of the provisions of this Chapter exists, and the property is unoccupied, appropriate City employees and their consultants may enter such property for the purpose of inspecting and investigating conditions and practices which may be in violation of this ordinance.
