City records indicate that only one main is present. Two water lines are shown in this area. Were two lines located during the main line investigation? The rain garden, riprap, storm pipes from the planters/trench drain, heat tape, concrete paver driveway and existing areas of the building encroaching into the easement shall be written into the easement agreement (attached to the comment letter email). COA Water and Attorney will review the proposed agreement and encroachments for approval. What is the estimated/expected vertical separation between the proposed storm pipes and water main/service lines? Previously Water preferred insulation to heat tape on storm pipes above the water main. This is pending approval by Water via the easement agreement. The landscape plans show plantings above the riprap area. Will these trees be planted outside the riprap and the dripline is just shown over the riprap? How will these be planted? Sightlines in the ROW need to be maintained. Height of landscaping needs to meet COA standards. These dogwoods are proposed directly above the water main. This is not permitted. Small shrubs are permitted in the easement however nothing can be planted above the water main. Clarify if this parking area is surrounded by a retaining wall or landscape curbing? The grading plan doesn't clarify if the curb is elevated. New retaining walls are not permitted in the ROW. State that an encroachment will be obtained for existing items in the ROW. The soils report calls out fill soils are in the area, how will the subsoil be prepared to ensure infiltration at the rain garden. The soils report recommends compaction however compaction typically doesn't permit infiltration. Per the URMP Appendix A, provide profiles of the proposed pipes.

The pipe for the planters runs down the easement. Revise the alignment so this pipe creates a minimized conflict if/when the Water Department needs to access this line. Can this pipe go straight across the easement or do grades not allow? The response to comments letter states the storm drain insulation is called out on the grading plan, I couldn't find this call out. It looks like heat tape is proposed instead? Water Department will need to approve heat tape in the easement. Insulation may be preferred. Show the 25' utility easement on this sheet so conflicts with storm infrastructure are shown. What happens to the runoff caught in the flowline at the end of the C&G? Creating negative drainage impacts on a neighboring property is not permitted. Show no negative impacts to downstream properties occurs. Provide C&G detail compliant with the Engineering Standards. It looks like a Type A barrier curb is proposed. Provide a detail for the beveled edge at the driveway entrance. It looks like detail #ENG-202H is proposed for the driveway entrance. Include this detail in the civil sheets as well. Is a T top patch proposed or will the new concrete butt up against the existing asphalt edge? COA standard is a T top patch. How can the alignment be shifted so the pipe in the easement is minimized? Is it possible to run the pipe perpendicular to the easement rather than at an angle? The response to comments letter states the storm drain insulation is called out on the grading plan, I couldn't find this call out. It looks like heat tape is proposed instead? Water Department will need to approve heat tape in the easement. Insulation may be preferred so frost depth is not changed. BY NO . DA T E PROJECT NO.

Anchor the RECPs with a row of staples/stakes approximately 12" (30cm) apart in the bottom of the trench. Backfill and compact the trench after stapling. Apply seed to the compacted soil and fold the remaining 12"(30cm) portion of RECPs back over the seed and compacted soil. Secure RECPs over compacted soil with a row of staples/stakes spaced approximately 12"(30cm) apart across the width of the RECPs. 3.Roll the RECPs (A) down or (B) horizontally across the slope. RECPs will unroll with appropriate side against the soil surface. All RECPs must be securely fastened to soil surface by placing staples/stakes in appropriate locations as shown in the staple pattern guide. 4.The edges of parallel RECPs must be stapled with approximately 2" - 5" (5-12.5cm) overlap depending on the RECPs type. 5.Consecutive RECPs spliced down the slope must be end over end (Shingle style) with an approximate 3"(7.5cm) overlap. Staple through overlapped area, approximately 12"(30cm) apart across entire RECPs width. Drawn on: 5-4-17 Disclaimer: The information presented herein is general design information only.
