“Daylight Plane” is intended to provide for light and air, and to limit the impacts of bulk and mass on adjacentproperties. The daylight plane restriction when combined with the maximum height limit, defines the “buildingenvelope” within which all new structures or additions must be contained. The daylight plane is an inclined plane,beginning at 18 feet above grade at the side property line, and extending into the site at 45 degrees from the verticalup to the maximum height limit. Main buildings shall not contain more than two stories and shall comply with theheight limits and daylight plane restrictions.

Daylight Plane - 2(Applicable to Main Buildings in all Single Family Zones, Except R-1A(BF) Sub-Zone. Zoning Graphic No. 18, Effective 11-03-16)(See CMC 86.04.245, 86.04.153, 86.08.030 & 86.10.030)

The following are exempt from the Daylight Plane requirements:a. The 45 degree off-set shall not be required along a side

property line which is adjoining and parallel to a public street, public alley or public open space.

b. The following features may extend beyond the daylight plane provided they are below the height limit:

i. Dormers, gables, cupolas, domes, skylights, parapet walls or similar architectural features provided that such features shall not exceed the height limit and the sum of the actual or implied volume of such features which project beyond the daylight plane shall not exceed a maximum of 100 cubic feet when both sides are combined *. Furthermore, no one side shall exceed 50 cubic feet except when along a “southerly side lot line” which shall be allowed a maximum of 100 cubic feet. The area of parapet walls, roof decks behind parapet walls and similar design features, shall include the volume bounded by the daylight plane, the vertical face of the parapet wall and a level plane at the top of the parapet;

ii. Cornices, eaves, and similar architectural features provided such features do not extend past the daylight plane more than 2 feet (flat roofs, flat eaves, continuous walls or enclosures of usable interior space are prohibited to extend past the daylight plane except as permitted above).

c. Chimneys and flues that do not exceed 5 feet in width, provided that chimneys do not extend past the required daylight plane a distance exceeding the minimum required by building codes.

d. Architectural features permitted by CMC Section 86.56.050.C.1.a-d.

e. Antennas.

* Volume of gable roof projecting beyond daylight plane = V

V in Cubic Feet = [Base(ft.)/2 X Ridge Length(ft.) ² ] 3

n architect or structural engineer m

ust certify that the nonconforming w

all(s) and foundation of a nonconform

ing structure to be retained are for the majority, in

acceptable condition. This certification shall be provided as part of the building perm

It is

the C

ity of

Coronado's

policy that

the proposed

construction of

subterranean garages/cellars w

ill, as part of the design process, include a hydrology study if the driveway

or walkw

ay to the underground garage begins its descent on City property (i.e., directly

behind the sidewalk).

On m

ost streets in the City, private property begins four feet behind

the sidewalk, or sixteen feet from

the curb face. It is the C

ity of Coronado's policy that the

sidewalk w

ill not be depressed in the area of the drivew

ay crossing. If the descending

driveway is w

holly contained within private property a hydrology study w

ill not be required. H

owever, a prudent developer w

ill have a study performed to clearly define the level of risk

exposure.

The C

ity of Coronado's property slopes up from

the top of curb to the private property line at a grade of 2%

. In m

ost cases, as discussed above, this is a rise of 0.32 feet. It is intended

that the flood waters associated w

ith the 100-year design storm be contained w

ithin the public right of w

ay, including the street, gutter and parkway area, until the w

ater can be transported to the storm

drain, and finally the ocean outfall. T

his containment of the 100-

year design stormw

ater is intended to minim

ize damage to private property.

Alteration

of this containm

ent area

by sloping

a drivew

ay dow

n to

an underground

garage/cellar within the public right of w

ay may cause extensive dam

age to private property as a result of flooding.

How

ever, depending on the topography of the particular location, a hydrology study m

ay reveal that there is adequate drainage, allowing the descent to private

property to begin in the public right of way.

The hydrology study m

ust be performed and stam

ped by a California R

egistered Engineer.

The study m

ust conform to the C

ounty of San D

iego Hydrology M

anual and be based on the 100-year design storm

. If the study show

s that flooding will occur during the 100-year

design storm

, the

subterranean garage/cellar cannot be

constructed. T

here w

ill be

no exceptions.
