CITY OF LAKE ELSINORE CITY HALL - REQUEST FOR ADDITIONAL AUTHORIZATION NO. 6
GRADING, DRAINAGE AND UTILITY PLAN MODIFICATIONS
Dear Gus,
Per recent conversations, we have revised grading, drainage and utility plans for the new City Hall to reflect the relocation of the existing alley access (driveway) and relocate the fire department connection from Main Street to Graham Avenue. Further, we have provided coordination and plan revisions related to potholing activities and upcoming video of the sewer lines in Main Street and Graham Avenue required by the Elsinore Valley Municipal Water District.
As part of the work, the following services are necessary to modify plans for the City and Elsinore Valley Municipal Water District (EVMWD) and provide supporting calculations and documentation.
1. Revise grading, drainage and street design and associated plans
2. Revise EVMWD plans to reflect new location of the fire department connection.
3. Coordinate potholing activities and add pothole data to plans.
4. Coordinate video survey of existing sewers on Main Street and Graham Avenue.
The Scope of Work outlined below provides further information into the plan modifications/additions result from the proposed work. Required revisions include the design of the following plan modifications:
Scope of Work
Grading, Drainage and Street Design – Modify the current plan set to account for the relocation of the existing access to the alley to the easterly edge of the city hall property. oModification of the street design along the south side of Graham Street including curb and gutter, sidewalk, and a new commercial driveway approach including an accessible path of travel.
Confirm the design of the proposed grind and overlay on Graham Street. oRedesign grading in the alley to provide access to the existing traveled way in the alley including grading and paving south of Graham Avenue and revised grading along the alley at the rear of the new building.
oModify drainage design at the northeast corner of the proposed building and along the alley reconstruction to accommodate the modular wetland and ensure adequate treatment of site runoff.
Fire Department Connection – Design related to the relocation of the fire department connection to Graham Street east of the proposed driveway. Remove the fire department connection from its current Page | 2

location on Main Street to the new location Graham Avenue. Provide design of the proposed waterline connection, piping, DCDA, post indicator valve, fire department connection, various check valves, and a new fire hydrant. Route piping from the fire department connection to the point of connection at the building. Prepare fire flow calculations for multiple scenarios based on the new design and previously acquired fire flow data from EVMWD.
Potholing – Coordinate potholing activities with USI, review and interpret pothole reports, and add tabulated pothole data the plans for EVMWD.
Sewer Video – Provide coordination, video review, and data interpretation for video footage of the existing sewers in Main Street and Graham Avenue necessary to locate three sewer laterals serving the three buildings that previously occupied the city hall site. Add sewer lateral locations to the EVMWD plans and coordinate abandonment thereof with District staff.
