Subject: 2018-070 Lighthouse Instruments-Final Site Plan
Chris,
RWSA has reviewed the final site plan for Lighthouse Instruments as prepared by Timmons Group and dated 7/10/2018,
with most recent revision dated 9/13/2018 and has the following comments:
Sheet C4.0:
1. Include the following RWSA sewer connection notes:
"All connections to RWSA manholes shall be watertight and made with a flexible rubber boot. All coring methods,
the coring contractor and all materials for construction shall be approved by RWSA in writing prior to
construction. RWSA Engineering Staff shall be present for all cores into the manholes. Bypass pumping may be
required at the sole discretion of RWSA staff. Grouting of the manhole bench or interior may be required,at the
sole discretion of RWSA staff,for a smooth transition of flow. Existing manholes shall be backfilled to original
grade to the satisfaction of RWSA. Contact RWSA Engineering a minimum of 3 business days in advance to
schedule a core of a manhole."
2. Show RWSA 30'sanitary sewer easement on this sheet(D.B. 369 P.248).
3. RWSA needs to see the profiles for the proposed storm drains, since the pipe is shown to cross the existing
RWSA sewer main adjacent to MCI-MH-36(between storm structures 102 and 104). RWSA will require a
minimum vertical separation of 18" between the existing sewer main and the proposed storm sewer line.
Please let me know if you have any questions.
Thank you,
Victoria
