CHAPTER 1 - INTRODUCTION

1.1 Background

The Erosion Control BMP Program includes the identification and evaluation of erosion at storm drain outfalls that discharge downslope of the roadbed. The following methodology was used to derive a prioritized listing:

• Perform field operations; • Assess and evaluate conditions; and • Develop quantitative criteria for evaluating erosion at storm drain outfalls.

A detailed description of the methodology is provided in Chapter 2.

1.2 Objectives

The objectives of this report include the following:

• To identify and prioritize storm drain outfalls on the island of Oahu that discharge downslope of the roadbed based upon water quality impacts as a priority;

• To develop and implement a program to prevent erosion at the storm drain system outfalls.

CHAPTER 2 - METHODOLOGY

2.1 Field Operations

Field operations were conducted between August 2005 and October 2006. The data collection efforts consisted of identifying and documenting storm drain outfalls along State highways. Field inspection priorities focused on assessing major outfalls, which are defined as culverts and pipes with an inside diameter of 36-inches or greater. The following activities were conducted at each outfall location: • Visual inspections of outfall area by a crew of one or two persons, using GPS units to locate

approximate outfall location. • Collect the following information about outfall area (See Appendix A for inspector’s

checklist): − Outfall size and type (material); − Condition of outfall; − Condition of outfall area; − Condition of outfall runoff, − Water flowing from outfall; − Pollution around outfall area; − Photographs; and − Sketch of culvert/pipe configuration

2.2 Quantitative Criteria

The high priority sites were selected by a combination of factors, including the observed erosion condition, watershed priority, receiving water body classification, overland flow distance to receiving water, culvert size, and soil condition (erodibility) at the outfall location. The ranking criteria (erosion values) are based on the following equation:

Erosion Value = (erosion condition factor) x (watershed factor) x (water classification factor) x (distance to receiving water factor) x (culvert size factor) x (soil erodibility factor)

Erosion Condition Factor

Erosion conditions were assessed by the inspectors in the field and recorded in the “Condition of Outlet Runoff” section of the Field Operations Inspector’s Checklist. This factor was divided into four categories. The highest tier consists of those outfalls that were observed to exhibit heavy or severe erosion. These locations were assigned a weight factor of 5. Outfall locations that showed evidence of mild or moderate erosion were assigned a weight factor of 2. Light erosion was assigned a weight factor of 1 and those areas were erosion was not evident was assigned a weight factor of zero.

Draft Islandwide Assessment of Erosion Potential at Storm Drain Outfalls On the Island of Oahu Page 4 March 2007

Watershed Factor

Each watershed was categorized into one of four classifications to determine the watershed factor. Critical watersheds are defined as those which have been designated by the EPA as a Wasteload Allocation (WLA). This constitutes the highest tier of the prioritization ranking and is assigned the largest weight factor of 4. The five watersheds that comprise this group are Kawa, Waimanalo, Ala Wai, Kawainui, and Kaelepulu. The second tier consists of the high priority watersheds as defined in the Consent Decree, Appendix A (Civil Action No. CV05-00636) and is assigned a weight factor of 3. High priority watersheds include Aiea, Halawa, Kalauao, Kalihi, Kaneohe, Kapakahi, Kaukonahua, Keaahala, Kiikii, Nuuanu, Paukauila, Poamoho, Waiawa, Waikele, Waimalu, and Waipio. The third tier consists of those watersheds that appear on EPA’s 303(d) list of impaired waters based on turbidity or total suspended solids. This group is assigned a weight factor of 2 and includes Anahulu, Hanauma, Helemano, Honouliuli, Kaaawa, Kahaluu, Kahaluu Segment, Kahawainui, Kapalama, Kaupuni, Kawaiiki, Kawailoa, Koko Crater, Makaha, Makaiwa, Moanalua, and Opaeula. The bottom tier consists of all remaining watersheds and is assigned a weight factor of 1.

Water Classification Factor

The water classification of the receiving water body was also taken into consideration in the quantitative analysis. The first category, consisting of Class A waters and Pearl Harbor Estuary, is assigned a weight factor of 1. The second category, Class AA waters, marine conservation areas, and reserves, are assigned a weight factor of 1.2, or 20% greater than the first tier. Watersheds that outfall to Class AA waters and other sensitive areas include: Manini, Kaluakauila, Anahulu, Loko Ea, Kahana, Hakipuu, Waikane, Waianu, Waiahole, Kaalaea, Haiamoa, Waihee, Kahaluu, Ahuimanu, Kahaluu segment, Heeia, Keaahala, Kaneohe, Kawa, Puu Hawaiiloa, Hanauma, and Makapuu. All remaining watersheds are assumed to drain to Class A waters or Pearl Harbor Estuary.

Distance to Receiving Water Factor

The proximity of the outfall location to the receiving water body was also factored into the analysis to account for sediment that may settle out prior to reaching the final discharge location. This factor is based on the distance along the approximate flow path from the outfall to the receiving water body. Flow distances through pipes and lined channels were subtracted from this measurement since it is assumed that 100 percent sediment transfer would occur through these conveyances. For outfalls near the shoreline, the distance to stream factor was terminated along any visible sandy beach (from aerial photos), rather than to the point where it contacts the ocean.

The receiving water was defined as (1) a blue line or water body on the USGS map, (2) a blue line as depicted in the State’s streams GIS file (darstreams.shp), or (3) a water body, as shown in the City and County of Honolulu’s water body shapefile (watbod.shp).

Culvert Size Factor

Prioritization of sites was also determined by culvert size. Culverts with inside diameters less than 36-inches are considered minor outfalls and are assigned a weight factor of 1. Those with inside diameters of 36-inches or larger are considered major outfalls and are assigned a weight factor of 2. Multiple barrel culverts less than 36-inches in diameter with an aggregate pipe cross sectional area greater than a single 36-inch diameter culvert are classified as major outfalls for

Draft Islandwide Assessment of Erosion Potential at Storm Drain Outfalls On the Island of Oahu Page 5 March 2007

analysis purposes. Since culvert size is an indication of the contributing drainage area, the larger drainage areas were afforded a higher weighting by this method.

Soil Erodibility Factor

The soil type in the vicinity of each outfall location was obtained from the City and County of Honolulu’s GIS layers. A corresponding “K” value was determined for each soil type based on USDA NRCS publications. These values ranged between 0.02 and 0.28. This erodibility factor quantifies the susceptibility of soil detachment by water and is commonly used to predict long-term average soil loss. For outfalls that exit directly into a concrete channel or other lined ditch, the soil erodibility factor was set to zero.

CHAPTER 3 - SUMMARY OF RESULTS

3.1 Summary of Results

A total of 1,189 outfalls were documented as of October 31, 2006. Each site was evaluated for erosion potential and ranked according to the calculated erosion value. Based on this analysis, a list of the top twenty-five islandwide erosional areas was compiled (Refer to Table 3.1). As illustrated in Figure 3.1, these high priority outfall locations are scattered across the island. It should be noted that this ranking of high priority outfalls is subject to change pending a more comprehensive, site-specific engineering analysis.

Eight of the top twenty-five outfalls are located in the Windward area, where critical (WLA) watersheds and Class AA waters are prevalent. The general soil classification is of the Lolekaa-Waikane association, which comprises approximately 15 percent of the island. This association is characterized by well-drained, fine to moderately fine textured soils on uplands,

Draft Islandwide Assessment of Erosion Potential at Storm Drain Outfalls On the Island of Oahu Page 7 March 2007

fans, and terraces. They formed in old alluvium and material weathered from basic igneous rock. These soils range from nearly level to very steep.

Figure 3.1: High Priority Outfalls

Eleven of the top twenty-five sites are located in central Oahu. The soil in this area is identified by the Helemano-Wahiawa association, which comprises approximately 18 percent of the island. This association consists of well-drained, moderately fine textured and fine textured soils on uplands which formed in material weathered from basalt. These soils are generally nearly level to moderately sloping.

Five sites are located within Lualualei-Fill land-Ewa association soil types. These areas consist of well-drained, fine textured and moderately fine textured soils on fans and in drainageways on the southern and western coastal plains. They formed in alluvium and are nearly level to moderately sloping. This association comprises approximately 14 percent of the island.

The final site, located in Waialua, is within the Kaena-Waialua association, which occurs as a narrow band along the northern and eastern coastline on the island of Oahu. They formed in alluvium and vary widely in texture and drainage. The deep, mainly nearly level and gently sloping soils consist of poorly drained to excessively drained soils that have a fine-textured to

coarse-textured subsoil or underlying material. They occur on coastal plains, talus slopes, and in drainageways. This association comprises approximately 10 percent of the island.

Additional information on the Top 25 sites is provided in Table 3.2, and individual site reports for the Top 25 sites are included in Appendix B. A comprehensive list of all outfalls evaluated in the study as of October 31, 2006 is provided in Appendix C. A data disk containing electronic files of the site reports for all documented locations will be included in Appendix D in the final version.

3.2 Remediation Measures

An outfall program consisting of assessment, prioritization, and implementation of remediation measures will be submitted and implemented per MS4 Permit requirements in late March 2007. Outfall assessments will continue with the completion of major outfall assessments by March 30, 2008. Outfall locations with observed erosional conditions will require the installation of velocity dissipaters or other BMP measures to reduce the risk of continued erosion at these locations. A PS&E process similar to the process used for the FY06 high priority erosional

Draft Islandwide Assessment of Erosion Potential at Storm Drain Outfalls On the Island of Oahu Page 9 March 2007

areas will be used to develop remediation methods for the prioritized outfalls. Implementation details, such as annual outfall BMP funding, have not been determined at the time of this report's completion.

3.3 Limitations The findings presented in this report are based upon information obtained from visual field inspections and as-built information. The degree of erosive conditions observed on the date of the most recent field survey is subject to change. The nature and extent of these variations may not be evident until subsequent field visits. If such variations occur, re-evaluation of the sites may be required. Additional limitations of this report include the following: • Outfalls included in this analysis are limited to those sites which have been physically

located in the field and surveyed by the inspectors as of October 31, 2006. The final version will include a comprehensive listing of all outfalls which traverse the State highway system or outfall into the State right-of-way to the maximum extend practicable; and

• The analysis is dependent on the site conditions on the day of the survey and does not take

into account the contributing drainage area, slope of the culvert, or exiting velocity of the flow.
