West Hills Innovative Stormwater Demonstration
Final Report, Chapter 4: Prioritizing the Projects
Intro

The projects included here are only a small handful of the myriad of opportunities that exist in the basin that drains to Mill Pond (See Fig 4-1 below, BMP stands for "best management practices" but in this report, they are simply referred to as "practices"). In addition to the many more sites available within the priority area, even more opportunities are available at the FHHOA outside the Mill Pond drainage area, where the HOA is generally less steep.

Figure 4-1: BMP ("Practice" for short) Priority Area
Responding to Stakeholders

A variety of messages heard at the ecocharrete workshop and numerous conversations with FHHOA stakeholders, especially Pam Morris (Board Liason), Meg Miller & Susan Weedall (G2 committee members) and Jennifer Callaghan (HOA Manager), narrowed the types and locations of the proposed project sites further. What follows is a discussion of those messages and goals, how they shaped the selection of opportunities, and the recommended projects themselves.

“Big impact”. The FHHOA Board wanted projects with big impacts, specifically projects that will reduce the volume of sediment entering Mill Pond.

Planning Response:
1. Larger site area opportunities were prioritized over smaller projects.
2. Lawns and grassy areas, which export the most sediment of any other land use area at the HOA, were prioritized over other more difficult to address areas like pavement.

Cost. Some additional implementation money for these projects is available in the future; however, discussion of raising the FHHOA monthly fees in the past, even by a small amount, is reported to have resulted in a tremendous push-back by residents.

Planning Response:
1. Early estimates from landscape contractors for a variety of proposed practices were obtained to inform decisions.
2. Projects that would appeal to a variety of grant funding sources were prioritized over projects with no grant sources. The FHHOA money that is available for implementation can be used as matching funds for future grants.
3. Projects where free materials are available now (bank stabilization with re-vegetation) were prioritized over projects with no immediate cost minimization resources.

Improved street safety. Many people are concerned with drivers who drive too fast on neighborhood roads.

Planning Response:
There are two street design opportunities at FHHOA that would slow traffic. The traffic calming effect of tree lined streets versus no trees has been well established in scientific studies. Also, narrowing driving lanes to 10 feet, instead of the typical 12 foot width given to drivers on highways such as I-5, slows traffic. This has been done throughout the HOA, but because there is excess parking available along many of these roads, they often seem much wider than a highway lane, encouraging drivers to speed up.

Providing two on-street parking spaces per house, a number of areas were identified as viable locations to remove excess pavement and plant additional shrubs and/or trees. See the section on “Depaving” for more information on implementation.

Preserve play areas in cul-de-sacs. One approach, removing pavement and replanting the center of a cul-de-sac (aka depaving into what’s called a “Pocket Park”), was promoted by stakeholders in the ecocharrette; however, this has been avoided. A few conversations later with homeowners and conversations with Meg Miller had with some of her nearby neighbors indicate that most owners would not want to lose the play area that the cul-de-sacs provide their community.

As a result, no cul-de-sac centers are proposed to be removed and replanted, although there are many great examples of these throughout the HOA and this is an encouraged practice. Some cul-de-sacs, however, are so large (90-foot diameter) and driveway alignments are located in such a way that specific portions of the cul-de-sac can be removed without impacting parking, without significantly impacting maneuverability, parking, or play areas (project 54). One other project (project 63) proposes that the existing cul-de-sac pavement be removed and replaced with permeable pavers, which will indicate to drivers that this area is designed for pedestrians (ex: kids at play) more so than for cars and has the effect (in numerous studies on what are called woonerfs, home zones, or complete streets) of creating a more safe condition for everyone.

Fig 4-3 While there are numerous attractive cul-de-sacs with vegetation and amenities in the middle, this approach was ruled out due to the limited flat areas and safe areas to play.

Consider icy/snowy conditions. Miller Road is a busy road and while there was some discussion regarding depaving “extra” pavement down the middle and creating a tree lined roadway, the extra pavement in the middle, especially on steeper areas, isn’t extra pavement at all, but needed as space for cars to drive around stranded vehicles. For this reason, depaving projects tend to be proposed on lower traffic areas and on areas that are too steep for bioretention facilities (aka green streets) but might still be considered some of the flatter areas of the FHHOA.

Address drainage & maintenance problems. A number of neighbors responded to the survey citing a variety of drainage areas including muddy yards (ex: project 61) and excessive runoff coming onto their property (ex: project 52). In addition, the HOA has a few areas known to be high maintenance, including Valley View Park (ex: projects 24, 32, 60, and 62).

Ranking Method
Projects are ranked:
  • First on what kind of practice it is and the overall ranking that practice was found to have when cost effectiveness in reducing runoff and sediment transport was examined (see Chapter 3)
  • Second, on the effectiveness of the individual project in reducing sediment
  • After these two criteria, some projects may be moved up in the FHHOA schedule based on observations, professional experience, and/or stakeholder input on whether the project will solve an existing drainage and/or maintenance problem. Projects with known drainage issuess are 7, 24 (lawn area at top of Valley View Park), 25, 27, 32 (Bioretention in Valley View Park), 36, 43, 45, 51, 52, 53, 60 (Porous walkway in Valley View Park).
