CITY OF REDONDO BEACH
Budget Response Report #45
June 14, 2022
Question:
What is the total estimated cost to design and install drought tolerant landscaping, past or Paid coast Hig waytain on the SCE right-of way property licensed by the Gily.
Response:
The City's current strategic plan includes an item to bring forward a conceptual plan for beautification and habitat restoration on the SCE right-of-way parcel, west of Pacific Coast Highway, recently licensed by the City. In preparation for that report, staff has engaged an on-call landscape architect and asked for some visioning documents regarding certain topics for future discussion such as grading and trails, planning scheme/palettes, accessibility, irrigation, signage, etc. While those plans have not been formally presented yet, the attachments include a portion of the Illustrative Site Analysis prepared by the consultant. Staff has also asked for high level budget numbers from the consultant (see attached).
The consultant's overall price estimate for construction costs to improve the roughly five acre parcel is about $1.37M. That price includes material and construction costs (detailed on the attachment), as well as a 15% contingency and a 30% premium for prevailing wage, which the City is required to pay. The resulting cost is about $277,000 per acre, or $6.35 square foot. By comparison, the cost to install improvements to the two parcels of SCE right-of-way adjacent to Artesia Boulevard cost about $450,000 per acre. That work, however, included a parking area, solar lighting, and more decorative plant landscapes. An additional 5% is included in the grand total of $1.44M to include soft costs associated with design and construction administration.
An additional request was made to include pollinator fountains, which are small water features that function to allow water collection by various insects and birds. Anything large scale would likely not be permitted by SCE. The City's license agreement with SCE prohibits installation of water storage tanks of any kind. However, there may be opportunity to add low profile water bubblers that could provide a similar function as part of the irrigation system and costs for these would be included in the general unit cost for irrigation included in the attached estimate.

Phased Approach
As an alternative, the City Council may wish to take a phased approach to completing the landscaping improvements on the right of way. For example, the Council may wish to initiate the work on the flatter eastern portion of the site, which is about 1.6 acres. Using the estimate provided by the consultant, improvements to this area could be performed for about $400,000 to $450,000. These figures include a scope of about 70,000 SF of planting area and temporary irrigation, and 12,000 SF of decomposed granite (DG) pathways. Currently there is about $138,000 available in the project account. Assuming the City Council wishes to proceed with the additional $312,000 appropriation needed to complete the work, staff would engage the consultant to prepare illustrative concepts to present to the City Council for preliminary consideration as part of the strategic planning objective and seek further direction on final design and follow up public outreach.
Funding for the additional $312,000 appropriation needed to fully install drought tolerant planting and pathways on the flatter, eastern portion of the SCE site is available in the Subdivision Park Trust (Quimby) Fund or from unallocated General Fund Balance.
