Lorimer Road Field Survey Notes (12/3/2015)

Lorimer Road Field Survey Notes (12/3/2015), by Eric Haugaard, with additions by Talal Shahbander, PE, Senior Project Engineer, City of Raleigh | Public Works, Design/Construction Division

  • Numerous road pavement patches…not sure if patches were for water or sanitary sewer repairscheck on next visit to determine if they run between sewer manholesif not inline between manholes, patches must be for water line
  • Comment from Aaron Brower (9/18/14) from Public Utilities… “there have been no water main breaks or sewer outflows reported, therefore existing infrastructure for water and sewer can remain”… will want to contact Public Utilities to get better information as to water and sewer pipe age and material…may want to video sewer lines…check as-built plans before contacting Public Utilities
  • Some alligator cracking in pavement…check on next visit to estimate quantity and extent
  • Some local settling of pavement (east side) observed in front of parcel 1321…check on next visit to get better estimate of pavement condition
  • Apparent water flows (debris left on pavement) running down (from north to south) Woodlinks Drive to Lorimer…Woodlinks Drive has existing C&G
  • Serious drainage issues (i.e. wet yards, erosion) in parcel numbers 1401, 1321, 3119, and 1315
    • Parcel 1401 is property that has existing 18” storm pipe conveying water under Lorimer from north side…as per GIS, this water is collected in a channel that runs from existing school (at Kaplan Ave) to Woodlinks Drive and carries/catches water from behind houses including parcels 1424, 1420, 1412, 1408, 1404, 1402, and 1400
    • Talked to owner of 1315 (Stan Pruitt) who made statement to the effect that “the City caused the drainage issues when Athlone Place and Delmont Drive were constructed and that this project better correct the problem”
  • A test well (4” cap) was spotted 3’ in from (north) edge of pavement approximately 40’ west of Merwin Road…looks pretty new/clean…need to find out (from the City) who installed this well to find out if it is still being monitored
  • Due to proposed 6’ wide sidewalk with 6’ setback on west side of road, retaining wall will have to be built for first two parcels east of Woodlinks Drive (parcels 1318, 1314) and possibly for a portion of 1304…resident (1318 Lorimer Rd) wants to make provisions in proposed retaining wall to allow for a stairwell connecting his front door to street…no promises made, but may be able to work into plans
  • Existing 15’x6’ box culvert (Bushy Creek)
    • Existing construction is pre-stressed concrete “T” joists for deck with cinder block side walls…two joists with severe cracking and/or loss of section of the bottom of the “T” near the upstream (NW) end
    • As per Walnut Creek Basin Study (2013, Dewberry), their recommendation is to replace existing culvert with two 12’x6’ reinforced concrete box culverts…this was suggested in this report as a solution to address flooding in houses adjacent to the creek
    • To maintain proposed section (i.e. 6’ wide sidewalk with 6’ setback) across this culvert, NW side would require widening
    • Existing 6” black (looks like cast or ductile iron) utility pipe installed between joists…will need to determine where water and sewer line locations crossing creek
  • Electric poles at intersection may have to be relocated
  • An existing sanitary sewer service line is exposed where it crosses the roadside ditch/swale
  • The curb inlets that are collecting runoff from intersecting side roads do not seem to be intercepting all of the runoff; evidence of overflow across the road was noticed.
  • A couple of sanitary sewer cleanouts were observed near the right of way line and may need to be relocated or adjusted
  • Some of the pipe culverts across driveways seemed to be undersized and /or plugged with erosion debris.
  • Water valves within the RoW were not visible and may be paved over
  • Two area drain inlets currently are collecting runoff on both sides of the Creek at street level and conveying the flow to the creek through discharge pipes at the creek culvert wing walls.
