CITY OF LAKE ELSINORE – NEW LIBRARY
Dear Gus:
Engineering Resources of Southern California, Inc. (ERSC), is pleased to provide this proposal for conceptual design and preparation of contract and supporting documents for a new public library. ERSC understands that the City of Lake Elsinore intends to construct a new public library and parking coupled with botanical garden at the intersection of Main Street and Sumner Avenue. The library and botanical garden will be located south of Sumner Avenue between Main Street and Spring Street and the parking facilities will be located on the southwest corner of Spring Street and Sumner Avenue.
Existing surface features observed are limited and include paved streets on Spring Street, Sumner Avenue and Main Street. These public improvements include curb, gutter and sidewalk on the west side of Main Street, the south side of Sumner Avenue and the east and west sides of Spring Street.
Otherwise, the location is dominated by native grasses and vacant ground. The specific location of the proposed facilities and improvements are described below.
• The library is located on the southwest corner of Main Street and Sumner Avenue. • The Botanical Garden is located on the southeast corner of Spring Street and Sumner Avenue. • The parking facilities are located on the southwest corner of Spring Street and Sumner Avenue.
In general, ERSC’ s Scope of Work will include preparation of conceptual designs and construction documents ( plans and specifications ), utility plans, erosion control plan, engineer’s cost estimate, hydrology report, stormwater pollution prevention plan, and a water quality management plan (WQMP, per Santa Ana Regional Water Quality Control Board Order No. R8 -2010-0033). Unless otherwise indicated by the City, we have assumed the City will provide topography for areas included in the project.
Based on public documents and a site visit, ERSC believes the project is constructable as envisioned by the City. However, there are certain issues th at will affect how ERSC approaches the conceptual (30%) and final design of the proposed f acility. These include grading , layout of parking facilities and water quality documentation. There issues are discussed in detail below.
GRADING – The site is characterized by generally flat terrain except along the e asterly edge of the evacuation channel. Based on our conversation, it is our understanding that the City intends to raise the

library site and the location of the botanical garden should be graded to sheet flow to the west. Further, the parking facilities located west of Spring Street will be graded to flow southerly so drainage can enter the evacuation channel via existing surface facilities. Raising the site will require import. Import for this project will be provided from the City Hall project and potentially the parking project at City Park.
PARKING FACILITIES – The project is subject to the parking requirement outlined in the City of Lake Elsinore Municipal Code Section 17.148. There is no specific requirement identified for libraries.
Therefore, the required number of parking stalls is unknown at this time. Parking ratios or area requirements will be investigated during the 30% Design Phase.
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 post construction site management.
The required WQMP must meet the treat and release standards included in the Guidance Document due to the project location in the watershed tributary to Lake Elsinore which limits treatment options to bio-retention. As discussed, the site will likely require two sep arate bio-retention facilities. One located on the east side of Spring Street to serve the library and botanical garden, and another located between Springs Street and the evacuation channel to serve the parking area. In addition, there is also the potential for one, or both, of these facilities to require a small pump station. The need for pumping facilities will not be known until we get into the final design.
