Lake Elsinore, CA 92530
GRAHAM AVENUE PARKING LOT – APN 374-262-013 & 018
Dear Gus:
Engineering Resources of Southern California, Inc. (ERSC), is pleased to provide this proposal for design and preparation of contract and supporting documents for a new parking lot located easterly of the Lake Elsinore Chamber of Commerce. ERSC understands that the City of Lake Elsinore intends to increase the public parking capacity for the near-by historic downtown Main Street and other amenities planned for the area. The City is currently in escrow to purchase the property adjacent to the Chamber of Commerce, at the intersection of W. Graham Aven ue and S. Spring Street . The property is located between W. Sulphur Street and W. Graham Avenue and occupies Assessor’s parcel 374 -262-013 and 374-262-018.
Existing surface features observed are limited and include commercial/retail buildings along the east edge, chain link fencing associated with Chamber of Commerce along the west edge , and limited vegetation (mature trees) scattered throughout the site. We are currently unaware of any utilities crossing the site and anticipate all utilities will be located within the public rights -of-way adjoining the site. In general, site grades are gentle and trend from the north to the south end of the property.
ERSC understands that th e city intends to maximize available parking at the site. In general, ERSC’s Scope of Work will include preparation of construction documents (plans and specifications), demolition plan, erosion control plan, engineer’s cost estimate, hydrology report, and a Water Quality Management Plan ( WQMP, per Santa Ana Regional Water Quality Con trol Board Order No. R8 -2010-0033). Unless disputed by the city, ERSC intends to use grading and pavement section recommendations from a similar nearby parking lot recently constructed south of Library Street and west of Main Street.
Based on public documents and a site visit, ERSC believes the project is constructable as envisioned by the city. However, there are certain issues that will affect how ERSC approaches the conceptual (30%) and final design of the proposed parking facility. These include concep tual design and water quality documentation. These issues are discussed in detail below.
CONCEPTUAL DESIGN – Based on public data, the site is 66.4 feet wide and 270 feet long. When contemplating the design of the parking lot, width of the parcel is a maj or consideration. At 66.4 feet it may be possible to design a facility with 90 -degree parking on both sides of a 20 -foot-wide drive aisle that supports one -way traffic. A layout with 90 -degree parking and a one -way, 20-foot-wide drive aisle

will include 5 -foot-wide buffer areas along the easterly and westerly sides and 18 -foot-deep parking stalls. The buffer areas will either be paved with stamped, colored concrete or utilized for water quality features.
The parking stall depth has been reduced by 2 feet to take advantage of available overhand into the landscape area. If the City feels this design is too limiting relative to the movement of the traveling public, the design will default to angled parking or parallel parking along both edges similar to the parking lot at City Park.
WATER QUALITY DOCUMENTS – The project is subject to the requirements of various water quality permits issued by the Santa Ana Regional Water Quality Control Board for construction activities and post-construction site management. These requirements include preparation of a Stormwater Pollution Prevention Plan (SWPPP) for construction activities and a Project Specific Water Quality Management Plan for prost construction site management. This site is not large enough to require preparation of a SWPPP but will require the development of an erosion control plan.
However, the site does require the preparation of a WQMP because the parking lot qualifies as a Priority Project as defined by the Guidance Document for the development of WQMP’s in this Santa Ana Region. Further, the required WQMP must meet the treat and release standards included in the Guidance Document due to its location in the watershed tributary to Lake Elsinore. This limits treatment options to bio -retention and has the potential to introduce a small pump station to the design pump station. If this is the case, ERSC will rely on Pacific Southwest Industries, a local vendor, to provide a package pump system for the discharge of treated runoff.
