In all use districts, a parcel of land or existing building expansion proposal, located within or adjacent to a critical area as identified in Chapter 18.10 CRMC, must first obtain a critical areas permit, prior to obtaining site development preparation approval or a building permit.
(Ord. 2018-02 § 2 (Exh. A), 2018)
In order to accomplish the purpose of this title, the following zoning use district classifications are established and regulations are established, addressing permissible uses, the height and bulk of buildings, the amount or percent of lot area in open spaces around the buildings and the density of population. Such classifications to be known as follows:
A. 
R-1 low density residential use district;
B. 
R-2 high density residential use district;
C. 
C-1 retail business use district;
D. 
C-2 highway business use district;
E. 
I-1 industrial use district.
(Ord. 2018-02 § 2 (Exh. A), 2018)
A. 
Each use district shall be delineated on a map entitled "zoning map of the city of Castle Rock," which, all together with explanatory material thereon, is adopted by reference and declared to be a part of this title.
B. 
The official zoning map shall be identified by the signature of the mayor of the city and attested by the city clerk-treasurer. A copy marked "Exhibit A" shall be located in the city clerk-treasurer's office and shall be final authority as to the current zoning status of land and water areas, buildings, and other structures of the city.
C. 
In accordance with the provisions of this title, if changes are made in district boundaries, or to their matters portrayed onto the official zoning map, such changes shall be made on the official zoning map, promptly after the amendment has been approved by the city council. The amending ordinance shall provide that such changes or amendments shall not become effective until they have been duly entered upon the official zoning map.
D. 
In the event that the official zoning map becomes damaged, destroyed or lost, or difficult to interpret, because of the nature or number of changes and additions, the city council may by resolution adopt a new official zoning map.
E. 
No changes of any nature shall be made in the official zoning map or matter shown thereon, except in conformity with the procedures set forth in this title. Any unauthorized change by any person or persons shall be considered a violation of this title and punishable as provided under CRMC § 17.80.060.
(Ord. 2018-02 § 2 (Exh. A), 2018)
When uncertainty exists as to boundaries of districts as shown on the official zoning map, the following rules shall apply:
A. 
Boundaries indicated as approximately following the centerlines of streets, highways, or alleys shall be construed as following such centerlines.
B. 
Boundaries indicated as approximately following platted lots shall be construed as following such lot lines.
C. 
Where a lot subdivided and recorded subsequent to the zoning of the area in which it is located becomes so placed that it is unequally bisected longitudinally by the boundary lines of a different district, the district boundary shall be considered as following the lot lines of the lot in such manner as to place the lot wholly in that district which applies to the major portion of the lot.
D. 
Where a lot is equally bisected longitudinally by two or more districts or district boundary lines, the total lot shall acquire the most restrictive use classification and the highest area required of the two zone classifications or area districts involved.
E. 
Where a lot is bisected by the boundary lines between two or more districts and such boundary line parallels or approximately parallels the street on which such lot fronts, the total area of such bisected lot shall acquire the same zone classification or area district requirement as the front portion of the lot. This provision shall not apply to through lots.
F. 
Boundaries indicated as approximately following city limits shall be construed as following limits.
G. 
Boundaries indicated as following railroad lines shall be construed to be consistent with railroad right-of-way.
H. 
Boundaries indicated as following shorelines shall be construed as to follow such shorelines and, in the event of natural meandering or changing in the shoreline, the boundary shall be construed as moving with the actual shorelines.
I. 
Boundaries indicated as parallel or extensions of features indicated in subsections (A) through (E) of this section shall be also construed to follow the parallel or extensions.
J. 
Where the street or lot layout actually on the ground, or as recorded, differs from the street and lot lines as shown on the zoning map, the planning commission, after notice to the owners of the property and after public hearing, shall interpret the map in such a way as to carry out the intent and purposes of this title. In case of any questions as to the location of any boundary lines between zoning districts, a request for interpretation of the zoning may be made to the planning commission and a determination shall be made by the city council.
(Ord. 2018-02 § 2 (Exh. A), 2018)

Distances shall be determined by the scale of the official zoning map.
The regulations set by this title within each district shall be minimum regulations and shall apply uniformly to each class or kind of structure or land, and particularly, except as provided as follows:
A. 
No building, structure, or land shall hereafter be used or occupied, and no building or structure or part thereof shall be erected, constructed, reconstructed, moved or structurally altered, unless in conformity with all of the regulations herein for the district in which it is located.
B. 
No building or other structure shall hereafter be erected or altered:
1. 
To exceed the height;
2. 
To accommodate or house a greater number of families;
3.

4. 
To have narrower or smaller rear yards, front yards, side yards, or other open spaces, than required in this title or in any other matter contrary to the provisions of this title.

No part of a yard or other open space, off-street parking or loading space, required about or in connection with any building for the purpose of complying with this title, shall be included as part of a yard, open space, or off-street parking or loading space similarly required for any other building, except as provided in this title.
D. 
No yard or lot existing at the time of passage of this title shall be reduced in dimension or area below the minimum requirements set forth herein. Yards or lots created after the effective date of the ordinance codified in this title shall meet at least the minimum requirements established by this title.
E. 
All territory which may hereafter be annexed to the city shall be classified in that zone most closely analogous to existing city zoning at the time of annexation.
