SUBJ: Study of Parking Demand for Phase II and
Phase III of Newport Dunes Redevelopment
Newport Dunes is ready to begin work on Phase II of its
Redevelopment Plan. Phase II contemplates expansion of the
existing marina from 230 to 430 slips and the construction of a
new restaurant on the former site of Anthony's Pier 2.
Construction of Phase III, the 275 room family inn, is not
expected to begin until 1991 or 1992.
The Newport Dunes Settlement Agreement does not specify the
precise number of parking spaces required for the development
encompassed in Phases II and III. Newport Dunes has commissioned
a parking study to analyze the peak parking demand of the final
two phases of the project (copy attached). The study is similar
to those considered by the City in approving the Four Seasons and
the Marriott expansion. According to the consultant, the marina,
restaurant and family inn would require a maximum of 867 spaces as
"stand alone" uses. However, the peak parking demand of each use
occurs at different times and the consultant believes 791 spaces
would be sufficient. Newport Dunes proposes to provide 939
spaces. Rich Edmonston and Jim Hewicker have reviewed the parking
study, believe it accurately reflects likely parking demand, and
recommend approval.
We recommend the City Council determine that the peak parking
demand for Phases II and III of the Newport Dunes Project are as
is accurately evaluated in the report prepared by Weston Pringle &
Associates. We also recommend that Newport Dunes be required to
provide at least 550 parking spaces for the development specified
in Phase II and a total of 939 parking spaces for the development

Dear Mr. Gleason:
C C � •.�
This letter summarizes our review of parking factors related ttZ— ecses II
and III of the Newport Dunes Redevelopment Plan. The review was based
upon information provided by you, field studies by our staff and standard
reference material.
PROJECT DESCRIPTION
The Newport Dunes Aquatic Park is, tieing redeveloped in three phases.
Phase I includes the public beach, day use parking, dry boat storage,
boat launch, recreational vehicle park and marina. Work on this phase is
currently nearing completion. Under Phase II, the existing marina will
be renovated and expanded form 230 to 430 slips. In addition, a new
restaurant will be built with a total public area not to exceed 15,000
square feet. Phase III would include a 275 room family inn with
restaurant, cocktail lounge. coffee shop, pool lounge. small meeting
rooms, recreation room and retail space. It is proposed that
approximately 50 percent of the guest rooms will have kitchen
facilities. Parking for 939 vehicles 1s available for Phase iI and III
uses.
EXISTING CONDITIONS
At present, a 230 slip marina is in operation and parking is provided for
this site. This provides a model to survey and utilize to estimate
future parking needs for this use. Records have been kept by the
operators of parking demands and these data from May 15 to July 15, 1989,

were reviewed. Review of these data indicated all spaces occupied on
July 4 with 105 parked vehicles at 4:00 PM on Sunday June 25, 1989, being
the second peak. These data also indicate peak demands during the
afternoon with reduced demands during other periods.
In order to validate these data, observations were made by Weston Pringle
and Associates staff on a weekend and weekday. The results of these
surveys are summarized in Table 1. Review of Table 1 indicates that
Sunday had the highest observed parking demand with the peak occurring at
2:00 PM when 132 parked vehicles were observed. This peak represents a
ratio of 0.57 parked spaces per slip. It can also be seen from Table 1
that morning and evening parking demands are approximately 69 percent of
the peak demand.
ANALYSIS
Determination of parking needs for multi use projects must consider both
the potential of joint usage and differing times of peak demands. In
this case, marina tenants could visit restaurants, inn guests could
patronize the free standing restaurant, RV park guests could patronize
restaurants and shops, and similar cross uses. In addition, non -guest
room facilities within hotels do not have the same parking requirements
as do similar uses that are free standing.
Marina
The field studies indicate that the existing marina had a peak demand of
0.57 parked vehicles per slip on a Sunday afternoon with the morning •and
evening demands being 69 percent of the peak, While the peak demand on
July 4th exceeded this observed peak, it is not reasonable to design for
a peak that may occur only two or three times per year. (This is similar
to not, providing for the peak Christmas shopping" demand at a shopping
center.) If the 0.57 spaces per slip ratio is applied to the marina, the
need for 245 spaces to serve 430 slips is determined. This would be the
daytime peak demand with the demand reduced to 169 spaces during evening
and morning periods.

Restaurant
The City of Newport Beach requires one space per 40 square feet of public
area for restaurants. Provisions are also included to require parking
ratios from one space per 30 to one space per 50 square feet of net
public area. Since there is a good opportunity for the restaurant to be
patronized by marina users, hotel guests and RV park guests, the lower
ratio of one space per 50 square feet would be applicable in this case.
This ratio would equate to a need for 300 parking spaces for the
restaurant.
Inn
Facilities such as inns, hotels and motels are each relatively unique and
generalized parking ratios may or may not apply. Parking ratios for
these facilities are generally based upon the number of guest rooms and
include needs for ancillary uses. The.wide range of parking ratios that
can occur at hotels is illustrated by the listing of various survey
results in Table 2.
The types of facilities listed in Table 2 are varying with some being
generally business types and others being destination resort type. Based
upon the description of the proposed inn, it is' felt that the Del
Corondado, La Costa and Newporter best represent the planned facility.
Of the three, the Del Coronado would best represent the concept for the
subject project. The ratio for the Del Coronado is also near the average
ratio.of the three hotels of 1:17 spaces per room. This average rate is
recommended for the subject hotel resulting in a need for 322 parking
spaces.
Combined Parking Needs
The preceding paragraphs have examined parking needs for each of the
three principal uses. Table 2 summarizes the projected parking needs for
each use. The peak demand for each use individually is listed and totals

867 spaces. Due to the characteristics of each use, all peaks would not
occur simultaneously. As indicated in the discussion of the marina
parking, the demand for this use 1s projected to be 169 spaces during the
evening. This evening period is when the restaurant and hotel would be
expected to be near peak. This scenario is also listed in Table 3 and
indicates a total parking demand of 791 which could be accommodated by
the 939 space supply.
Studies such as the Urban Land Institute's "Shared Parking" have
indicated that hotel peak demands typically occur after 9:00 PM and
before 7:00 AM. This would indicate a further reduced demand during peak
restaurant periods. The proposed inn could be expected to exhibit these
characteristics due to the attractiveness of the area such as Disneyland.
Knotts, other restaurants and general tourist facilities. While this has
not been quantified or applied, it does support the adequacy of the
supply to serve the proposed uses.
It should also be noted that no reduction in demands have been assumed
for cross over users such as marina tenants or RV guests eating at the
restaurants or hotel guests eating at the free standing restaurant.
These conditions provide a safe margin for the parking adequacy.
SUMMARY
This study has reviewed parking needs for Phases 11 and III of the
Newport Dunes Redevelopment Plan. _ Existing conditions were examined to
quantify marina parking characteristics. Previous studies were reviewed
to determine parking factors for the restaurant and inn uses. On a
individual basis the theoretical demand does not exceed the supply. The
differing peaking characteristics result in a further increased supply of
parking space. An estimated peak demand of 791 spaces was developed
which can be accommodated by the 939 space supply. This estimate did not
consider multi stop visits or the fact that hotel and restaurant parking
peaks are not coincident. On this basis, it is concluded that the
proposed parking supply will be adequate to accommodate the planned uses.
