After reviewing the site plan and phase diagram provided by you and visiting the site, we have developed a significant understanding of the issues and constraints related to the development of new RV Park at the proposed site. SITE DESCRIPTION The project is located in the City of Lake Elsinore on the westerly shore of the lake and easterly of Riverside Drive (SR 74) at Lincoln Street. The site is the location of a recently improved access road and boat launch with parking, restrooms and picnic facilities. The balance of the site is dominated by an existing RV Park, sand beaches and an undeveloped area along southerly edge of the property. The site is characterized by relatively flat terrain that slopes generally in an easterly direction to the lake. The westerly portion of the site is currently developed as a RV Park. In this area, the vegetation is moderately dense and includes shade trees shrubs and grass. Additional improvements in the developed portion of the site include paved roadways and RV sites, an administration building and subsurface utilities including power, water and sewer. Various RV sites throughout the park have differing levels of utilities ranging from full hook ups to dry camping. It appears the majority of the sites have water and power while the RV sites along Riverside Drive provide water, sewer and power. However, it has been indicated by Park staff that the sewer hook ups along Riverside Drive are slowly being abandoned due to a blockage that is causing the sewer to back up. Other facilities identified at the site include two restroom buildings, one of which appears to be abandoned, a small maintenance yard and limited fire protection facilities. The restroom 3550 E. FLORIDA AVE., SUITE B HEMET CA 92544 (951) 765-6622 (951) 765-6621 FAx buildings are both connected to septic systems that will require proper abandonment during the reconstruction of the park. Abandonment of these systems will be incorporated into the demolition plan. In addition, an existing well has been identified at the southerly edge of the maintenance yard. Signage at the well indicates the water is not potable, therefore, we assume it will be abandoned as well. Wharf head fire hydrants throughout the site indicate the existence of an onsite water system. However, the size and location of these facilities and the source of supply are currently unknown. Construction of the launch ramps and associated parking, restroom and picnic facilities appear to have been coupled with a new lift station located westerly of the restroom building. The lift station is enclosed by a block wall and, based on current research, appears to be owned and operated by the Elsinore Valley Municipal Water District. As indicated below, we have assumed this lift station and the associated force main have the capacity to serve the park once it has been redeveloped. The portion of the site southerly of the existing RV sites is generally flat and extends from Riverside Drive easterly to the lake's shore. The area is generally covered with fallow ground and native grasses near Riverside Drive, but transitions to trees and shrubs closer to the lake. This area also supports a small fenced storage area. Existing public improvements at the site are Iimited to Riverside Drive along the westerly frontage. Riverside Drive provides one lane of traffic in each direction with a center left turn lane and left turn pockets. An existing traffic signal controls the movement of traffic through the Tee intersection at Riverside Drive and Lincoln Street. In addition, there are water and sewer facilities within the right-of-way of Riverside Drive that are operated by the Elsinore Valley Municipal Water District. PROPOSED IMPROVEMENTS Proposed improvements at the La Laguna RV park are categorized as onsite and offsite. In general, the onsite improvements will include grading and drainage, circulation, water and sewer and water quality best management practices. These civil site improvements will facilitate the construction and installation of RV sites, sites for tent camping, cabins, an administration building, showers and restrooms and other recreational amenities. Currently, the only planning document available is a site plan, prepared by STK Architecture, Inc., which provides for the general layout of the RV sites, tent camping, cabins, recreational amenities and site circulation. We are unaware of any planning document(s) that address the overall site grading or the water, sewer and drainage needs of the site. Therefore, we anticipate the development of final construction drawings in three phases including: Schematic Design including an overall grading concept and the preparation of master Engineering Resources of Southern CA, Inc. Proposal for the La Laguna R V Park Page 2 water, sewer and drainage concepts for the site. Design Development including the development of plans for grading, drainage, water sewer, erosion control and support documents such as hydrology, hydraulics, construction and post construction phase water quality management, fire flow calculations and preliminary cost estimates. Plans and documents prepared during this phase will be approximately 50 percent complete when presented to City staff. Final Construction Drawings including plans, documents and cost estimates described above, along with specifications developed to the level of 100 percent complete. In addition to the proposed onsite improvements, there are certain offsite improvements necessary to provide access to site for users and public safety personnel. The site plan provided by STK, provides for ultimate street improvements at the Lincoln Street entrance that extends northerly to the existing access road. Based on the Circulation Element in the City's General Plan, the ultimate section on Riverside Drive provides for six lanes of traffic, a raised median and bike lanes in a 120 -foot wide right-of-way. In addition, the offsite improvements include a deceleration lane for north bound traffic entering the project at Lincoln Street and a third entrance to the project at Lake Crest Drive. Key to the discussion of the concept plans and preliminary and final construction drawings are the assumptions made during the development of the work scope associated with each item. Therefore, the assumptions made during the preparation of this proposal are listed below. 1. Water and Sewer service will be provided by the Elsinore Valley Municipal Water District, 2. The sewer lift station near the restrooms at the boat launch has the capacity to serve the entire site. 3. Street improvements shown on the site plan prepared by STK Architecture Inc., will be built to the ultimate width. 4. The street improvements will require an acceleration lane at the northerly end of the proposed widening 5. Traffic signal modifications at Lincoln Street will be limited to the project side of the street. A scope of services based on these assumptions will provide the basis of the fee estimate presented in Exhibit "B." If the underlying assumptions are modified during research or the Schematic Design phase, an appropriate modification to the scope or work and estimated fees will be negotiated with the City. SCOPE OF SERVICES AND FEE ESTIMATE Our Scope of Services and Fee Estimate are based on the completion of projects of similar size and scope, a field review of the site and surrounding improvements and conversations with STK Architecture Inc. Engineering Resources of Southern CA, Inc. Proposal for the La Laguna RV Park Page 3 For your review, we have prepared the following documents: 1.

This analysis will give consideration to impacts at adjoining streets and roads, boat launch facilities, parking and existing utilities during the development of an overall grading concept for the site. The Mass Grading Plan will be a concept level plan that incorporates the projects surroundings, existing improvements and proposed amenities into an overall grading plan that provides for the logical development of the site. Site grades will be developed to promoted phased development of civil site improvements and utilities while taking advantage of recreational blocks for water quality management and runoff storage. Tiered grading techniques will be utilized to maintain the integrity of the amenities and concept of each recreational block. Earthwork calculations will be prepared based on finished contours, undercut street sections and recessed areas to be utilized for retention and water quality. Prior to presentation of the grading concept to City staff, the site grades will be adjusted to provided a balanced site or as closed to a balanced site as possible. Conceptual Drainage Plans — Concurrently with the development of the Mass Grading Plan, develop an overall plan for the installation of drainage facilities, retention areas and water quality management features. The plan will be developed with primary consideration given to project phasing and the orderly development of drainage and water quality features. Development of the conceptual drainage plan will be based on runoff quantity and volume for the 10- and 100 -year storms resulting from the completion of calculations based on methods accepted by Riverside County. Hydraulic calculations will include normal depth calculations for all drains 15 -inches in diameter and smaller, a hydraulic profile for drains larger the 15 - inches in diameter and routing calculations for all retention basins.
