MEMORANDUM

Date: December 16, 2016

To: Sean Bechta (Ascent Environmental)

From: Jimmy Fong and David Carter (Fehr & Peers)

Subject: DGS 1215 O St and P St Office Building Projects –

Existing Parking Supply and Availability

RS16-3489

This memorandum documents the existing parking supply and availability of the surface lots, garages, and

on-street parking within the vicinity of the DGS 1215 O Street Office Building and P Street Office Building

projects in Downtown Sacramento.

Parking Locations

The parking supply study area covers roughly a two-block radius around both project locations. This study

area extends from 5th Street to 14th Street, and Capitol Mall to Q Street (with a few areas extending east to

15th Street and south to R St) [see Figure 1].

Parking facilities within this area include a mix of on-street parking, surface parking lots, and garages, some

of which are reserved for employees of the State of California while others are open to public. Public parking

locations include a few private-operated parking garages with an allocation open to the public. The on-

street parking included in the survey are all metered parking and non-metered 2-hour/residential permit

parking (loading zones were excluded).

Parking Supply and Availability

Fehr & Peers conducted parking supply and demand counts at all parking locations on mid-week days in

mid-November with clear weather conditions (Wednesday, November 15, 2016 and Thursday, November

16, 2016), during the peak parking demand for office employees between 9 AM to 11 AM and 2 PM to 3

PM (excluding lunch-time parking demand).

The P Street Office Building Project site includes reserved parking for state employees, as well as parking

reserved for patrons of the Capital Athletic Club [see Table 1]. This area includes 281 parking spaces in

which 208 were occupied.

In the parking study area (excluding the P Street Office Building Project site), there is a total supply of

approximately 6,530 parking spaces. During the peak parking demand period for office employees, the

total availability was approximately 1,450 spaces [see Table 2]. Reserved parking spaces located in private

garages (i.e., not available for public parking) are not included in the reported supply/availability numbers.

1 Parking supply, peak demand, and availability in the study area excludes parking within the P Street Office Building Project site

(presented in Table 1).

2 1500 10th Street Garage is a State parking facility that allows for public parking; it is included in the State reserved supply and

availability.

3 Public parking includes private lots and garages with an allocation for public parking; reserved parking for non-State employees

are excluded in the supply and availability for this facility type. Westminster Presbyterian Church (1300 N Street), Quill Alley

(between 7th and 9th Streets), and 7th/R Street parking lots offer public parking rented on a monthly basis.

Locations with the highest number of available spots were in the following parking garages:

293 available spaces in the 1517 11th Street State Garage (between 11th/12th/O/P Streets)

201 available spaces in the 1517 13th Street Public Garage (between 13th/14th/O/P Streets)

183 available spaces in the 1416 10th Street State Garage (between 9th/10th/N/O Streets)
