Beginning with the 2017 Annual Report, Permittees shall report annually the loads reduced using the default (from the Fact Sheet) or alternative approved assessment methodology to demonstrate cumulative PCBs load reduced from each control measure implemented since the beginning of the Permit term. Permittees shall submit all supporting data and information necessary to substantiate the load reduction estimates, including appropriate reference to the control measures described in the reporting required under C.12.a.

Discussion San Francisco Bay Regional Water Quality Control Board staff has reviewed the FY 2015-16 WMA reports and has provided comments for improvement for the FY 2016-17 WMA reports. Those comments will be summarized at the July 19th Management Committee meeting. An example template for the FY 2016-17 WMA reports will be presented, and staff will review a timeline and summarize where input will be needed from Permittees. Staff will also answer any questions.

Staff Recruitment Status and Augmentation Strategy

Recommendation: RECEIVE an update from the Steering Committee on efforts to recruit staff to fill current vacancies and efforts to provide additional staff resources to the Program until the County can backfill the positions, CONFIRM membership of the Steering Committee and role, and AUTHORIZE the Administrative Committee to approve contracts for additional staff resources and request the County execute the contracts. AUTHORIZE the Steering Committee to explore procuring additional staff resources for the GIS project and the Administrative Analyst role if necessary. Background: In May of this year, the Management Committee formed a Steering Committee to address Program staffing and structure issues, including issues associated with the retirement of the Program Manager and the unexpected retirement of the Administrative Analyst. The County’s solicitation and selection process to fill the Program Manager’s position has not been successful to date. The County will be conducting another solicitation, this time with an increased salary, but it will take some time. With Program staff currently reduced by 40% excluding part-time clerical staff, the Management Committee has directed the Steering Committee to investigate means to provide staff resources on a temporary basis until the County can backfill the positions. While the work of the Steering Committee will initially focus primarily on the Program Manager position, the Committee is also charged with additional staffing needs as well as other Program sustainability issues. The Steering Committee currently consists of Rinta Perkins, Robert Ovadia, Donna Feehan, Chris McCann, Steven Spedowfski, Mike Carlson, and Rachel Kraai. Mitch Avalon is organizing and facilitating the Steering Committee meetings.

Discussion: The Steering Committee met on July 11, 2017 and identified and analyzed several options to provide staff resources to the Program for a 3 to 9 month time period. The Steering Committee identified the five following options that warranted further consideration:

- Job Share – project level. A City would provide staff with the appropriate skill set to take over the lead of a Program project (the GIS project is an example).

- Job Share – program level. A City would provide appropriate staff to perform the duties of the Program Manager on a half-time or up to full-time basis for at least a three-month period of time.

- Recent Retiree. The County would contact recent retirees who have experience in stormwater permit compliance or a similar field and see if any would be interested in temporarily filling the Program Manager position.

- Consultant. The County would contact consultants with experience in stormwater management to find out if they have anyone available to temporarily fill the Program Manager position.

- Temp Agency. The County would contact temp agencies that provide municipal services to determine if they have anyone available to temporarily fill the Program Manager position.

The Committee identified additional information that would be needed to make a decision on the various options and set a subsequent meeting for two days later. The Steering Committee met again on July 13, 2017. Five recent retirees had been contacted; two were not interested or unavailable, one had failed to reply, and two expressed interest. One temp agency was contacted, Municipal Resources Group, which does not have anyone with specific stormwater experience available for the job at this time. The Committee decided to take an incremental approach to developing a list of qualified applicants. The first steps are to interview the two retirees that are interested as well as send out an e-mail to the Management Committee and the City-County Engineering Advisory Committee to see if there are any City/Town staff available for job sharing. If one of the retirees is a perfect fit to meet Program needs, then the process may end. If not, job sharing will be further explored and an informal request for proposals to consultants will be distributed.

Fiscal Impact: The approved Program Budget includes the fully burdened salary of a Program Manager. This position has been vacant since April 1, 2017, creating a budget surplus that grows each day it is vacant. The County has offered and the Program has accepted the assistance of consulting services from Watershed Resources Consulting beginning in June, which is reducing but not exceeding the daily cost of a Program Manager. It is anticipated that the total additional cost of providing temporary staff resources to fill the Program Manager vacancy, in whatever form it would take, will not exceed the budgeted cost of a Program Manager.

Date: July 19, 2017 To: Management Committee From: Dan Cloak Subject: Staff Report B Hydromodification Management (HM) Technical Report – Update

Recommendation: Receive an update on preparation of the HM Technical Report, which is due with the 2016-2017 Annual Report. Background: The Management Committee last received an update on this project in April. At that time, the Committee approved expenditure of $60,000 in project budget contingency to complete the Technical Report and related work. Consistent with the intent noted in the April staff report, staff has directed the prime consultant, Tony Dubin, to expend no more than $20,000 of this amount in advance of a meeting with Water Board planned for June/July, and no more than an additional $20,000 for preparation of the Technical Report submittal following the meeting, leaving $20,000 for responding to the expected minor Water Board staff comments on the report. The following progress was reported in April:

• A project workplan was prepared and provided to Water Board staff.

• The workplan was presented and reviewed in an October 21, 2016 meeting with Water Board staff.

• A summary of the October 21 meeting was prepared and forwarded to Water Board staff to validate the consensus reached and for their review and comment.

• A December 7, 2016 email from Water Board staff was received and reviewed in a conference call with CCCWP staff.

• Field work was completed, including investigations of 15 Contra Costa sites on creeks downstream from areas where development is likely to

occur.

• Initial modeling runs were conducted to identify the relative sensitivity of sizing factors to the values of various parameters. Results suggest that minimum HM facility sizes are sensitive to assumptions regarding future increases in watershed imperviousness and the lower threshold for sediment movement (e.g., 0.1Q2 v. 0.2Q2) are somewhat sensitive to facility exfiltration rate to native soils, and are not particularly sensitive to geomorphic parameters such as channel dimensions or slope.

• The results, and the December 7 comments, were reviewed and discussed in a March 21 presentation and meeting with Water Board staff.

Status: Consistent with the project workplan and schedule, since April the project team has focused on modeling how natural variation and uncertainty of values for the “sensitive” variables influences the calculated sizing factors. (The sizing factors are used to determine the minimum size of bioretention facilities and other Integrated Management Practices (IMPs) that must be incorporated into land development projects.) A meeting of the project team with Water Board staff is scheduled for July 20. In preparation for that meeting, the project team prepared and sent to Water Board staff, on July 13, the attached “read ahead” set of slides. The slides include an update on the technical work and also include nomographs showing the relationship between the assumed threshold for incipient motion (e.g., 0.1Q2 or 0.2Q2), the assumed percolation rate of treated runoff into underlying natural soils, the assumed imperviousness of the project watershed once completely built-out, and sizing factors for bioretention facilities. At the July 20 meeting, the project team will also solicit feedback from Water Board staff regarding the sequence and schedule for obtaining a Water Board staff response to the Technical Report and preparing a complete set of sizing factors to replace those in Table 3-6 on p. 39 of the Stormwater C.3 Guidebook, 7th Edition. Implementation of the updated criteria for HM facilities is due by January 3, 2018. Attachment:

Hydromodification Management Applicability Maps--Update

Recommendation: Receive an update on the preparation of Hydromodification Management (HM) Applicability Maps. Background: A 2003 amendment to Contra Costa municipalities’ stormwater NPDES permit required the Permittees to prepare a Hydrograph Modification Management Plan (HMP). The HMP was submitted to the Water Board in mid-2005 and received Water Board approval in mid-2006. Implementation of the requirements began in October 2006 with publication of the 3rd Edition of the Stormwater C.3 Guidebook. The 2003 amendment stated that the HM requirements did not apply to developments where the project discharges into creeks or storm drains where the potential for erosion is minimal. The amendment noted such situations may include creeks that are “concrete-lined or significantly hardened downstream to their outfall in San Francisco Bay, underground storm drains discharging to the Bay, and construction of infill projects in highly developed watersheds…” and required that guidelines be included as part of the HMP. Contra Costa’s 2005 HMP included such guidelines; unlike the HMPs prepared for Alameda, Santa Clara, and San Mateo counties, it did not include maps delineating where HM requirements applied. Rather, in Contra Costa, applicants are required to determine the characteristics of drainage infrastructure downstream from their project all the way to the Bay. Projects could be designated to present a “low risk” of causing stream erosion if downstream drainage infrastructure consisted of “enclosed pipes; channels with continuous hardened beds and banks engineered to withstand erosive forces and composed of concrete, engineered riprap, sackcrete, gabions, mats, etc.… channels subject

to tidal action [and] channels shown to be aggrading, i.e., subject to the accumulation of sediments.” This same criterion was included for Contra Costa municipalities in the 2009 Municipal Regional Stormwater Permit (MRP 1.0, Attachment C). The 2015 Municipal Regional Stormwater Permit (MRP 2.0) consolidated HM requirements regionally. In this consolidation, rather than being designated “low risk,” some types of projects are exempted outright, including projects “located in a catchment that drains to a hardened (e.g. continuously lined with concrete) engineered channel or channels or enclosed pipes that extend continuously to the Bay, Delta, or flow-controlled reservoir, or drains to channels that are tidally influenced.” Note this language adds a reference to flow-controlled reservoirs but omits the previous reference to aggrading channels. An additional exemption, previously available in Alameda, Santa Clara, and San Mateo counties, but not in Contra Costa County, was included: projects “located in a catchment or sub watershed that is highly developed (i.e., that is 70% or more impervious).” MRP 2.0 also states, in Provision C.3.g.i.: “Permittees that do not have the location-based applicability criteria… shown on existing maps shall develop, or require to be developed, new maps, overlays to existing maps, or other equivalent information that demonstrates whether a project falls under…” either the exemption for hardened drainage or the exemption for highly developed catchments. The provision further states that the maps, overlays, or equivalent information shall be acceptable to the Executive Officer and shall not be effective until accepted by the Executive Officer.” MRP 2.0 Provision C.3.g.vi.(1) states: “New HM Applicability Maps or equivalent information prepared pursuant to Provision C.3.g.i. for those Permittees who do not have an approved Map, shall be submitted, acceptable to the Executive Officer, not later than the second Annual Report following the Permit’s effective date.” This would be the Annual Report due September 30, 2017. CCCWP’s 2016-2017 budget included $100,000 for preparation of the maps. Project Tasks and Results to Date CCCWP staff directed Dan Cloak and Psomas to use current GIS technology and the most recent applicable data, as well as the current criteria in MRP 2.0, to prepare the maps.

Determining HMP Applicability Technical Memorandum: Mapping Methodology

Background The Contra Costa Clean Water Program (CCCWP) assists Contra Costa County, the 19 incorporated cities and towns in the County, and the Contra Costa County Flood Control and Water Conservation Districtto comply with the Municipal Regional Stormwater Permit issued by the California Regional Quality Control Board for the San Francisco Bay Region. The permit was reissued in 2015. Permit provision C.3. requires Permittees to “use their land use planning authorities to include appropriate source control, site design, and stormwater runoff pollutant discharges and prevent increases in runoff flows from new development and redevelopment projects.” Permit Provision C.3.g. states requirements for Hydromodification Management (HM) to be applied to applicable new and redevelopment projects. Hydromodification is generally defined as changes in channel form associated with alterations in flow and sediment due to past or proposed future land-use alteration. Hydromodification management has emerged as a prominent issue because degradation of the physical structure of a channel is often indicative of and associated with broader impacts to many beneficial uses, including water supply, water quality, habitat, and public safety. Conversely, reducing hydromodification and its effects has the potential to protect and restore those same beneficial uses. 1 Permit Provision C.3.g.i. defines which new and redevelopment projects are HM projects. HM projects are projects that create and/or replace one acre or more of impervious surface except when one of the following applies:

1. The post-project impervious surface area is less than, or the same as, the pre-project impervious surface area.

2. The project is located in a catchment that drains to hardened (e.g. continuously lined with concrete) engineered channel or channels or enclosed pipes that extend continuously to the Bay, Delta, or flow-controlled reservoir, or drains to channels that are tidally influenced.

3. The project is located in a catchment or subwatershed that is highly developed (i.e., that

is 70% or more impervious). Provision C.3.g.i. also requires:

Permittees that do not have the location-based applicability criteria… [2 and 3 above] shown on existing maps shall develop, or require to be developed, new maps, overlays to existing maps, or other equivalent information that demonstrates whether a project falls under one of those two criteria.

CCCWP retained Psomas to prepare the maps on behalf of the Permittees.

Assessment of Available GIS Datasets The following municipal and county-wide GIS datasets were requested from the Permittees and evaluated by the Psomas team:

• Stormwater infrastructure (e.g. pipelines and channels)—to determine where infrastructure has been hardened.

• Streams, wetlands, and other water bodies—to determine natural streams and earthen channels that need to be protected..

• Hydrologic basins / sub-basins (if available)—to determine hydrographic areas and natural stream flow directions.

• Digital elevation model (DEM)—terrain data, to be used if hydrographic sub-basins were not available for the entire county and needed to be derived from land topology.

• Datasets from which imperviousness is an attribute or could be derived—to help determine areas where criterion #3 above is met.

The following GIS datasets were received and assessed. Storm Infrastructure Data from Permittees The storm drain infrastructure GIS data received was deemed mostly adequate for determination of hardened stormwater conveyances. Completeness of infrastructure representation will be validated through permittee review of final maps. Observations for these datasets: The quality and completeness of storm drainage infrastructure data received varied from

agency to agency. Overall quality and completeness is unknown. No datasets included the direction of curb flow.. In many cases, it was not possible to determine flow direction from datasets, which were

largely derived from CAD systems.

Page 45: MANAGEMENT COMMITTEE MEETING AGENDA Wednesday, …...Jul 19, 2017  · A. Fiscal Year 2016/17 Municipal Annual Report Packet: Kraai introduced Adrienne Miller from Geosyntec Consultants.

PSOMAS 2017-07-07 Page 3

The data seemed to be most complete for pipes; other conveyances were listed as “channels”, “ditches”, and “creeks,” and the nomenclature was not consistent among the datasets.

Stormwater drainage systems generally, but not always, follow land topography. Psomas used hydrographic sub-basins as a secondary means of determining drainage areas and flow direction. Sub-basins were not available for the entire county; however, =a high-resolution county-wide digital elevation model (DEM) was available. Psomas used the DEM to generate hydrologic sub-basins via standard GIS-based hydro-analysis techniques. CARI and BAARI Streams and Wetlands The California Aquatic Resource Inventory (CARI) and Bay Area Aquatic Resource Inventory (BAARI) stream data was determined to be adequate for determination of tidally influenced channels and to provide a visual reference for non-hardened stormwater conveyances. Observations for these datasets:

• Identify streams as either “fluvial” or “tidal” and “natural” or “unnatural” o “Fluvial Natural” are streams to be protected by HMP o “Tidal” very helpful in identifying tidally-influenced stream / channels o “Unnatural” could indicate hardening or altered alignments with earthen channel

sections. • BAARI data includes wetlands category “bay lands”

Stream / channel data completeness appeared to be good from CAARI/BAARI and other sources. However, no data source provided quality information of whether a channel was earthen, concrete, rip-rap, or some combination thereof. It was concluded that whether a channel was hardened would need to be assessed by visually assessing the available ortho-photography (more about this in the next section). Storm Water Utility Fee—Equivalent Runoff Unit Data The Storm Water Utility Fee (SWUF) Equivalent Runoff Unit (ERU) data provided by the County was not useful for determining percent impervious for a geographic area, due to the structuring of the data and large holes in coverage. Observations for this dataset:

• Parcel-based dataset • Equivalent Runoff Unit (ERU) can

be converted to percent impervious for the parcel using the formula %Impervious = ERU*3,300 / Parcel SqFt., however:

o Forced ERUs can result in percent impervious > 100% Figure 1. ERUs Assigned to Individual Buildings

PSOMAS 2017-07-07 Page 4

o Standardized ERUs assigned to very small parcels result in percent impervious > 100%

• Data does not cover entire county • ERU values not calculated for exempt properties (e.g. local, state, or federal government

owned parcels) • ERU not represented accurately geographically:

o ERUs assigned to individual building parcels—see Figure 1 o Total ERU for single-owner multi-parcels assigned to the parcel that includes the

primary office, examples: trailer parks, DOW Chemical National Land Cover Dataset (NLCD) The NLCD impervious data was determined adequate for identifying hydrological areas that are 70% or greater imperviousness. Observations or this dataset: • Percent impervious calculated from

satellite imagery • 2011 raster dataset with 30m

pixel resolution • Percent imperviousness represented

geographically • Good spatial alignment with county

datasets. Contra Costa County GIS Datasets Various GIS datasets supplied by the County were used as basemap information and instrumental supporting the HMP applicability analysis. Observations:

• Parcels—complete and up-to-date • Watersheds—useful for administrative / jurisdictional purposes, but not precisely-aligned

with topography • Sub-basins—not available for entire county • Digital Elevation Model—county-wide coverage with apparent high resolution and quality

Methodology for Determination of HMP Applicability Areas The following methodology was used to to create a HMP Applicability GIS layer for further mapping and analysis purposes. Step #1—Create Sub-basins Psomas created hydrologic sub-basins based upon topography using the Contra Costa DEM—see Figure 3. The process used hydro-analysis software tools provided with the Esri ArcGIS Desktop—Spatial Analyst software extension. The sub-steps were:

• Fill sinks • Set flow direction • Calculate flow

accumulation • Generate streams (simulated streams based upon flow accumulation threshold) • Determine stream links (stream segments defined by stream confluences) • Create sub-basins

(hydrographic areas) for each stream link

• Convert raster sub-basins to vector sub-basin polygons

The end result was a sub-basin polygon and generated streams polyline vector GIS layers—see Figure 4. Step #2—Perform Overlay GIS Analysis on Impervious Data A GIS overlay zonal analysis was performed to determine the average percent impervious for each sub-basin using the NLCD impervious raster layers as data source. A clip of the results for the Richmond area is shown in Figure 5. The areas in red were

70% or greater impervious and areas in deep yellow were 65% to 70% impervious, i.e. just missing the cutoff. Step #3—Determine Tidal-influenced Areas The BAARI / CARI datasets were used as the primary data source reference to determine tidally-influenced areas. The extent inland that streams and channels were attributed as “tidal” established the boundary limit. Any flat, low-lying, land area between two tidally-influenced stream segments were also determined to be tidally-influenced, since that area shares the same hydrological characteristics. Areas marked “bay lands” were presumed to also be tidally-influenced.

Step #4—Determine Channel Hardening As described in the previous section, there appeared to be no suitable county-wide data source that adequately defined the degree to which a channel was constructed of hardened materials (e.g. concrete, rip-rap). Psomas established channel hardened / non hardened status through visual interpretation of the available ortho-imagery. The following were used as guidelines.

• Curvy streams / channels tend to be natural.

• Straight-line and engineered curve channels tend to be man-made. • Narrow channels with vertical concrete sides are assumed to have hardened bottom. • Lack of heavy vegetation (trees, brush) indicate a hardened channel.

Channel status (hardened/unhardened) will be validated through Permittee staff review of final maps.

Step #5—Manually Code Sub-basins for HMP Applicability An “HMP Category” attribute was added to the Sub-basins GIS layer with the following possible coded values:

• Bay Lands—not subject to HMP due to tidal influence. • Tidal Influenced—not subject to HMP as channels / streams are tidally influenced. • Exempt > 70% Impervious—not subject to HMP as sub-basin has average

imperviousness > 70%. • Hardened—not subject to HMP as the area drains to the Bay or tidal-influenced areas

through continuous hardened storm drain infrastructure. • HMP Applicable—contains or drains to an unhardened stream or channel.

Each sub-basin was evaluated manually and assigned to the appropriate HMP Category using the GIS datasets described previously as visual input. An example of the process is depicted in Figure 7. In this example, the stormwater flows from a hill ridgeline bordering the right (East) side of the area and then flows to the left (westwardly) towards the main channel, then North and exiting the area through the main channel in the top left corner. Through interpretation of the ortho-imagery it was determined that this main channel transitions from natural to hardened where the background color changes (you can also see the transition from curvy natural to engineered man-made in the layout of the channel). It was also determined that this main channel stays hardened continuously through to a tidally-influenced area. As a result of the above interpretation, the sub-basins that contained stormwater lines (red) that drained to the natural sections of the channel were coded as “HMP Applicable” (green background). Sub-basins that contained stormwater lines that drained to the hardened section of the channel were coded as “Hardened” (dark grey background). The exception were the sub-basins that extend to the right that start out as urban area and end in undeveloped areas. In those cases, the sub-basin was manually split at the natural-urban boundary and the upper

PSOMAS 2017-07-07 Page 8

portions were coded as “HMP Applicable.” In this manner, any new development that expands to the west will fall under HMP requirements and any infill projects within the “Hardened” areas will not. HMP applicability of sub-basins will be validated through Permittee review of final maps. Step #6—Permittee Review A set of HMP Applicability maps have been created, one for each permittee, and distributed to Permittee staff for quality review and red-line markup. The purpose is to validate the interpretations made by the development team with first-hand knowledge of the characteristics of local channels and other stormwater infrastructure. The paper and electronic (PDF) red-line markups will be preserved and changes made by permittees will be recorded in notes as attributes within the sub-basin GIS layer. From this set of markups, the Psomas team will create a final version of the HMP Applicability maps and submit those to individual permittees for final review and approval. Permittee approvals will be documented and archived for historical reference and accountability. Step #7—Merge Sub-basin Polygons The Sub-basin layer with HMP Category attribute and notes will remain the master record. An optimized version of the HMP applicability layer will be created to enhance fast display and analysis within the GIS by merging contiguous areas of HMP applicability.

Results GIS Layers The result are county-wide GIS layers that can be used for mapping, analysis, and the foundation for the HMP web application to assist in determining HMP applicability for proposed development projects. Observations / Conclusions The densely urban areas of Richmond, El Cerrrito, Walnut Creek, Pleasant Hill, Concord, Antioch, and Oakley are largely either hardened or tidally-influenced, as expected. Most (or all) of San Pablo, Pinole, Hercules, Orinda, Lafayette, Martinez, Moraga, Danville, San Ramon, Clayton, Pittsburg, and Brentwood, as well as all unincorporated areas of the County, fall under HMP applicability. The large flat low-lying area to the immediate South East of Brentwood is currently coded as “HMP Applicable” due the limited extent of BAARI/CARI designation for Bay Lands or tidally-influenced streams/channels in that area within their datasets. That area should be analyzed to determine if they should be designated as tidally-influenced. Imperviousness of a sub-basin greater than 70% is a high threshold. Only one sub-basin in downtown San Pablo met this threshold that was not already exempt for being tidally-influenced or hardened. High imperviousness, as could be expected, is highly-aligned with urban areas near the Bay that tend to have hardened or tidally-influenced storm infrastructure.

7/14/2017

Definitions

• Hydro-modification—changes in channel form associated with alterations in flow and sediment due to past or proposed future land-use alteration

• Hardened Channel—a stream or channel is hardened if it is not susceptible to scouring or reshaping as the result of stormwater drainage

• Sub-basin—a hydro-geographic area that drains to a single downstream point

7/14/2017

Guidelines

• Overall Objective—protect vulnerable sections streams and channels from hydro-modification by incorporating HMP into new development projects in all drainage basins upstream of those sections

• No Points of Susceptibility—there must be no points of susceptibility at any point of the entire downstream drainage from that sub-basin to either a tidal-influenced area, designated Bay land, or to the Bay/Delta

7/14/2017

Guidelines

• Modification to Sub-basin Boundaries—changes to the sub-basin boundaries are appropriate when local knowledge or field investigation is applied

• Developed / Undeveloped Boundary—if a sub-basin is partially-developed and the drainage through the developed portion is hardened and the drainage through the upstream portion is unhardened (natural), then the sub-basin can be divided at the urban/natural boundary

Permittee Map Review Tasks Permittees are being asked to have their staff red-line the draft HMP Applicability maps provided to them to correct any errors. The review should be performed by permittee agency personnel that are familiar with the local storm drainage infrastructure. It is anticipated that most mapping errors will be revealed by systematically manually inspecting the maps for the following two conditions: 1. Streams and Channels Vulnerable to Hydro-modification versus Hardened An initial determination of where channels are hardened was attempted by visually interpreting available ortho-imagery (satellite photos). Permittee staff should review the hardness of streams and channels, as shown on the draft maps, based on their knowledge of the local drainage system and by field-checking where necessary. 2. Stormwater Pipeline Flow Directions Permittees should review the flow directions of all stormwater pipelines, and should pay particular attention to any that cross sub-basin boundaries. Based on local knowledge of pipe and gutter flow directions, and on field-checking where necessary, portions of sub-basins or entire sub-basins may need to be re-classified as to HMP applicability.

Definitions / Guidelines The following are general definitions and guidelines to follow when reviewing the draft HMP Applicability maps:

• The overall objective is to protect vulnerable sections streams and channels from hydro-modification by incorporating HM into new development projects in all drainage basins upstream of those stream and channel sections.

• A sub-basin is a hydro-geographic area that drains to a single downstream point. Sub-basins were generated by hydrographic computer analysis of the terrain. The sub-basins are being used as representative geographical base unit areas of the drainage system, which are then coded as to their HMP applicability.

• A stream or channel or stream is hardened if it is not susceptible to scouring or reshaping as the result of stormwater drainage, which generally means it is either fully concrete, on the bottom and banks, or has a concrete bottom with rip-rap banks. Generally, only engineered channels are considered “hardened.” A linear accumulation of rip-rap or other measures placed to control localized erosion does not qualify a reach as “hardened.”

• All areas upstream of any non-hardened stream reach are HMP applicable. Therefore, it is not critical to determine the status of a reach that is upstream of a reach known to be unhardened. To put it another way, for parcels within a sub-basin to be considered exempt from HM requirements, there must be no points of susceptibility at any point of the entire downstream drainage from that sub-basin to either a tidal-influenced area, designated Bay land, or to the Bay/Delta.

Updated 2017-07-14 2 of 3

• Changes to the sub-basin boundaries are appropriate when local knowledge or field investigation shows that portions of a sub-basin drain to pipes or hardened channels (all the way downstream) and not to a natural stream. In these cases, the sub-basin should be divided and the subdivided portions assigned HMP applicability as appropriate.

• Stormwater pipelines, as well as concrete curb and gutter flow, are hardened infrastructure. If a gutter and pipeline system drains to a vulnerable stream or channel, then the entire sub-basin, including the areas served by hardened infrastructure, will be coded as “HMP Applicable.” Conversely, if all the gutter and pipeline systems within a sub-basin drain to hardened channels all the way downstream, then the entire sub-basin will be coded as “Hardened.”

• If a sub-basin is partially-developed and the drainage through the developed portion is hardened (using the above definitions) and the drainage through the upstream portion is unhardened (natural), then the sub-basin can be divided at the urban/natural boundary. The upstream portion will be coded as “HMP Applicable” and downstream portion will be coded as “Hardened.”

• If there are both susceptible streams and hardened channels in a sub-basin, and it is not known if all drainage systems drain to the hardened channel, then the sub-basin will be coded as “HMP Applicable.”

Red-Line Instructions Permittees will review draft maps to verify the hardened/unhardened status of channels and the HM Applicability coding of sub-basins—and, where there are errors, correct them through the following red-line markup techniques. Hardened/Unhardened Channels Mark the extent of hardened and unhardened stream channel as precisely as possible. Add any supporting notes, such as source of information, or date field-checked. Entire Sub-basin If the entire sub-basin or multiple sub-basins are incorrectly designated, circle the area and provide the correct designation. Provide a justification for the change. Split Sub-basin As necessary, sub-basins can be split and divided into two or more smaller sub-basins in order to fine tune the HMP-applicability coding. When this is appropriate, draw the split lines as accurately as possible so there is no confusion as to which pipelines, stream sections, and so forth, are contained in each portion. Please provide the correct HM applicability for changed portions and justification for the changes. Red-line Submittal Red-lines can be submitted as red pencil or ink markups on printed paper maps or electronic red-line markups of the PDF file.

Date: July 19, 2017 To: Management Committee From: Rachel Kraai, Senior Watershed Management Planning Specialist Subject: Staff Report D Update on the Contra Costa Watersheds Stormwater Resource Plan Project Recommendation Receive an update on the Contra Costa Watersheds Stormwater Resource Plan (SWRP) Project. Background

In July 2016, the CCCWP was selected to receive a Storm Water Grant Program Proposition 1 Planning Grant for the development of the Contra Costa Watersheds Stormwater Resource Plan. The grant agreement was executed in May 2017. The awarded grant amount is $499,420 with a match amount of $500,540.

The SWRP will use a watershed-based planning approach to develop stormwater management projects which will help meet water quality requirements and provide additional benefits such as flood control, habitat restoration, community enhancement, and groundwater recharge where possible. A SWRP is now required in order to receive stormwater management funding from many different State grant sources. The SWRP will also help Contra Costa municipalities meet the green infrastructure plan requirements of their NPDES stormwater management permits.

Discussion The SWRP Project Team is currently making progress on a large number of activities, including, but not limited to, the following:

• Consolidation of spatial data for the project and an assessment of data gaps • Collection of existing stormwater management project concepts from stakeholder

organizations throughout the county for inclusion in the planning process • Development of the analytical methodology for the planning process including an

assessment of potential modeling tools • Implementation of the stakeholder/public engagement plan • Facilitation of the project’s Technical Advisory Group meetings. The first meeting of

the project’s Technical Advisory Group was held on June 27th

• Development of the first quarterly report and project invoice for submission to the State Water Board

In order to develop the first quarterly report and invoice for submission to the State Water Board, Program staff need documentation of all hours Permittees have spent on the project, as these hours can be counted as in-kind match under the grant agreement. Management Committee representatives received an email on July 12th from Contra Costa County Finance staff Shirley Lau requesting that documentation of in-kind labor hours be sent to her by July 21st in order to meet the submission deadline for the quarterly report. Lau’s email also included an updated version of the “SWRP Grant Match Documentation Guidance”. Program staff requests that Management Committee representatives gather all documentation per the updated guidance instructions and submit it to Lau by the July 21st

deadline. At the July Management Committee Meeting, Program staff will discuss project progress. Program staff will also discuss impacts to the project schedule due to the Program Manager and Administrative Analyst position vacancies. Fiscal Impact: The fiscal impact to the Group Program is $150,000, which is included in the adopted FY 16/17 and FY 17/18 Group Program budgets. Attachment(s): None.

a.m., followed by self-introductions, she proceeded to the agenda.

2. Closed Session: Budget Review and Planning: Vice-Chair Booth began the closed session at 9:50 pm. There was nothing to report from the closed session. Paquette discussed additional buffer in budget to assist permittees with individual monitoring-issues/questions. Paquette reported that the Program is going to extend contracts to end of permit term, and explained the reasons going to 3-year contracts versus continual one year contracts, made sense. Staff discussed issues with individual contractors and sought feedback of Permittee’s preferred approach. Paquette introduced the idea of cost sharing on projects of regional benefit between CCCWP Permittees. Amanda explained some options for funding Countywide and regional projects. Option 1: When project comes up, everyone contribute money at that time. Option 2: Start setting aside money every year to make sure funds are available when project is determined. Issues of how much to reserve and equity between Permittees, when a project used to reduce County-wide Mercury/PCBs loads is not in their jurisdiction. Staff explained basic regional funding concepts for benefit of the new Pinole member. This topic is one of politics and needs to be considered by much higher level group than this. Tamara Miller remarked that from a City’s point of view, it is difficult to get local money for regional projects (i.e., PCBs in Richmond; why does Clayton, Pinole have to contribute to that?). Focusing on one thing (i.e., PCBs) will not get it sold The committee concluded that there needed to be a separate meeting to discuss options and determine next steps.

Finally, in a non-budget related item, Paquette asked for feedback from Permittees about what the best way to make agencies/people aware of the occurrence of the pesticide toxicity issues in the County. Miller suggested that Staff present the issue with as much neutrality as possible. Paquette added that when the Program becomes fully staffed (Program Manager replaced), that she could compile the information gathered over the past few years for State and Regional efforts, and the two CCCWP Stressor Source Identification projects focused on Pesticide Toxicity, and present it first to the Monitoring Committee and then the Management Committee to remind Permittees of the ongoing issue and why it is a problem.

3. Announcements: Fan Ventura announced that the PIP Committee has tasked the Program subcommittees with providing input for the soon-to-be revamped Program website. She wanted the Committee to look at website pages that are related to monitoring and let them know if the information contained is still valid and concise. Also, if the Committee has any reports or web links that should be on the Website, please let her know within 60 days. The PIP Committee plans to roll-out the new Program website in Spring 2017. Cece Sellgren asked if the domain for Pesticide’s Linger is still owned by the Program. Ventura stated that it is still owned by the Program for now.

4. Approval of Minutes: Moved/Seconded (Sellgren/Mancuso) to approve the November 11, 2016 draft minutes. Item passed unanimously.

5. Mercury and PCBS Controls (Provision C.11 and C.12) A. Status Update for PCBs Source ID: Paquette gave the Committee an update on

the City of Pittsburg’s PCB source property on Willow Pass Road. The City is waiting for the San Francisco Regional Water Quality Control Board (Water Board) to sign off on the operations and maintenance agreement. After the Water Board signs off, the property will be counted for the PCBs TMDL load reduction. Booth stated that the City of San Pablo is still trying to discover the PCB source at her Rumrill Green Streets Project on Rumrill Blvd. San Pablo has received money from the Environmental Protection Agency (EPA) to install bioswales on the property and on Rumrill Boulevard. She’s also looking at getting additional funds from California Natural Resources Agency. She will make a presentation about her project at the Regional Roundtable Meeting on March 28. Michele Mancuso stated she’s still working on the Unincorporated County’s North Richmond PCB referral project.

B. GIS Status and Next Steps for C.11/12 Reporting: Paquette gave a brief summary on the Pollutants of Concern Steering Committee Meetings that have been attended by EPA Staff, Water Board Staff and Regional Permittees. Currently the BASMAA Development Committee and Monitoring Committees have been discussing the minimum data needs for tracking and reporting PCBs. The next Joint BASMAA meeting is planned for March 2nd. CCCWP are cost sharing their GIS platform development with the Alameda County Clean Water

Program for Geosyntec’s expertise and participation. Paquette recommended that Permittees look at the C.11. & C.12 section of their FY 2015/16 Annual Reports to determine missing project details for inclusion into the GIS database for the load reduction accounting in the 2017 Annual Report. Paquette will make this announcement to all Permittees at the next Management Committee meeting. Paquette informed the Committee that the Clean Watersheds 4 Clean Bay project is wrapping up. They will hold a project workshop on April 7 to present the outcomes from the grant project. Guidance documents, draft reports and a web portal were developed as resources for Permittees to use when considering PCBs and Mercury source control implementation projects. Paquette will send more information to the Committee when it becomes available.

C. BASMAA Update: Paquette gave an update to the Committee on the upcoming BASMAA regional projects. Consultant EOA is developing a white paper to evaluate utilities, to determine if their vaults and transformers are causing PCBs to get into the receiving waters. The potential outcome from the white paper could be to have the Water Board put it in a 13267 Request to the Utility companies, which could request information from utilities (e.g. locations, concentrations and/or volumes of spills). The BASMAA Board of Directors is also in the process of approving an Interim Accounting Tool and Guidance in 2017. The BASMAA PCBs in Infrastructure Caulk project team will be developing criteria and soliciting for infrastructure that would be a suitable candidate for being sampled. Paquette asked the Committee to send her any such candidates. The BASMAA BMP Effectiveness Monitoring project will be looking at different control measures and sampling that can be done in the current permit term. The BASMAA PCBs in Building Materials project has not gotten started yet but should be in April. Finally, CCCWP has directed Dan Cloak to be on the Project Management Team for the RAA Guidance Document project. Khalil Abusaba, independent of the CCCWP is sitting on the Technical Advisory Committee for the Project. Both Consultants are reporting updates to Staff and Management Committee as needed.

6. Water Quality Monitoring (Provisions C.8.d,e,f,g): A. Monitoring Update: Paquette informed the Committee that Contra Costa

County successfully sampled the overflow from the Marsh Creek Reservoir for

mercury and methylmercury samples in the January 8th storm. The sampling is compliant with our Alternative Approach to Pollutants of Concern Monitoring which proposed to collect samples from the Upper Marsh Creek watershed during 2 storms, when the reservoir overflowed. This is the first year in 5 that the reservoir has overflowed. The results will be included into the Final Methylmercury Control Study Report, which is due to the Region 5 Central Valley Water Board in 2018. Paquette reported that further POC sampling for copper and nutrients will be done by the Program in lower Marsh Creek and Walnut Creek this winter.

B. UCMR Report – Paquette asked the Committee if they’d like to include Armand Rubys year’s long study that began in 2012 on pesticide toxicity in the UCMR. The Committee concluded that if it’s not a permit requirement then it should not be included. Booth commented that in the UCMR, the term homeless encampment should be changed to illegal encampment. She said the language assists code enforcement officers who have to remove people who are trespassing in creek areas. Mancuso commented that references to Alamo Creek in the UCMR were inconsistent and confusing. Paquette asked the Committee to send any further questions or comments regarding the report to her by February 24. The Committee will approve the final report at their March 13 meeting and it will need to be approved by the Management Committee on March 15. Paquette also asked the Committee for recommended sites for sampling for bacteria, temperature by April 1, 2017.

7. Old/New Business: Paquette announced that RMP monitoring group SFEI has sampled sites in Contra Costa County. She will update the Committee with those results. She also informed the Committee that the State Water Board has distributed a Lyris Listserv with the receiving waters’ results on a new 303d list. Booth announced that the building that housed the Doctor’s Medical Center in San Pablo will be demolished and turned into a parking lot. She’s recommending to BASMAA to have that building tested for PCBs.

(Chair) County Flood Control District Cece Sellgren/Michele Mancuso City of Pinole Amelia Timbers City of Pittsburg Jolan Longway City of Richmond Joanne Le (Phone) City of San Pablo Amanda Booth (Vice-Chair) Program Staff: Lucile Paquette, Erica Lashley-Cornell, Beth Baldwin Guests: Willis Logsdon (UC Berkeley Graduate) 1. Introductory Remarks: Vice-Chair Amanda Booth called the meeting to order at 10:05

a.m.; followed by self-introductions she asked if there were any announcements or changes to the agenda. Lucile Paquette introduced graduate student Willis Logsdon who has expressed an interest in doing an internship with the Program. Paquette asked to remove the approval of minutes from the agenda and she will have them on next month’s agenda. Paquette announced that the BASMAA Interim Accounting Methodology was approved and will soon be implemented. She also announced that Program Analyst Fan Ventura will be retiring next week.

3. Program-Directed Monitoring (Provisions C.8.d,e,f, g) a) Trash Receiving Water Monitoring Plan: Paquette introduced Beth Baldwin

who began her PowerPoint presentation on the draft BASMAA Trash Receiving Water Monitoring Plan (Plan). She described the background of the Permit requirement for the Plan and the work BASMAA is been doing to get the Plan approved and submitted to the San Francisco Regional Water Quality Control Board (Water Board) on or before the July 1, 2017 deadline. After the presentation she asked for feedback from the Committee. Amanda Booth was concerned about the liability issues that may ensue from this plan. She suggested caveats to prevent agencies from suing Permittees over trash and adding language stating that the studies are based on a non-scientific method. She also recommended that the results be reported publically on the Program’s website instead of through CEDEN.

b) WY 2017 Creek Status & POC Monitoring Update: Program staff is getting

permissions, permits and insurance for sampling at different sites throughout the County. The team is currently are focusing on finding targeted sites to

sample for bacteria and pesticide/toxicity monitoring.

c) MRP 2 Stressor/Source Identification (SSID) Workplan Planning: Paquette is working with Program consultant Khalil Abusaba on drafting an SSID concept for Monitoring committee review. The SSID project for the MRP 2 Permit term must be based on the table of exceedances reported in the WY 2016 Urban Creeks Monitoring Report. Sampling showed exceedances in temperature, insects and bacteria as well as PCBs. Paquette has recommended that the project look for sources of PCBs and mercury that may be loading directly to the Bay. She gave examples of two properties that could be studied and sampled in the County. She also discussed a second project option investigating the appropriateness of using the California Stream Condition Index in the SF Bay region. She asked the Committee to send her any feedback they have on the project concept. She will introduce the idea at the next BASMAA Monitoring/Pollutants of Concern (MPC) meeting.

4. C.11/12 Mercury and PCBs Controls a) PCBs Source Properties Referrals Update: Paquette gave committee members

an update on the source property referrals to date. The Program is waiting for confirmation from Water Board staff on how they’ll except/enforce referrals from properties located in the eastern portion of the County, so East County Permittees have an avenue to claim pollutant load reductions. She’ll check in them at the June MPC meeting. Booth informed the Committee that San Pablo will get ~14 grams credit for the cleanup at Rumrill Sports Park. Paquette stated that Program consultant’s ADH are still investigating the other PCBs source on Rumrill Blvd to determine if a specific source can be pinpointed.

b) TSCA/WB Clean-Up Site Investigations: Paquette received a spreadsheet on Department of Toxic Substances Control (DTSC) properties from Water Board staff. She is reviewing the spreadsheet to see if any properties have been redeveloped so they can be reported to the Water Board for PCBs load reduction credit. Cece Sellgren requested information on how to get credit for properties that were redeveloped. The Committee discussed options for getting credit for those properties and Booth stated that they do not currently have enough source properties to meet the PCB load reduction requirements in the MRP. Paquette stated she will make an announcement at the next Management Committee meeting that additional source property screening is needed.

c) AGOL PCBs Beta-Testing and Loads Accounting Estimations: There will be a meeting next week with Program consultant’s PSOMAS to discuss the accounting methodology process that will be integrated into the Arc GIS online application for tracking C.3 projects and loads removed from the control measure implementation. Paquette will begin entering the ArcGIS referrals into the database. After the beta testing process has concluded, Permittees will be

able to upload their PCBs data.

5. BASMAA Update a) RAA Guidance Document: Paquette discussed the BASMAA regional project

that is developing a guidance document to define the parameters for conducting a Reasonable Assurance Analysis in the Permit area. Program consultant’s Khalil Abusaba and Dan Cloak will be representing Contra Costa on the project committees and she will have an update at the next meeting.

b) C.8/C.11.12 Infrastructure Caulk and BMP Monitoring: BASMAA will have their sampling plan available on May 24. They still need locations to sample infrastructure caulk in roadways and storm drain infrastructure that were built during the 1970s and 1980s. She’ll send more details when available.

c) PCBs in Building Demolition Materials: Paquette informed the Committee that BASMAA still needs a manager for this project. She asked members to check with their municipalities to see if they have appropriate individuals who could volunteer for the assignment.

d) 5-Year Bioassessment Report: This project is an analysis of the data collected during the Creek Status Probabilistic Monitoring Plan that has been occurring during the last 5 years. BASMAA is currently developing a request for proposals, with a goal of the Project being contracted and starting in July. While it is not a permit requirement, the results will be valuable to Permittees and the public.

e) BASMAA POC Steering Committee: The committee is looking at large PCB spills that recently occurred. BASMAA is preparing a utility white paper to get information on spills from local utility agencies. The next committee meeting will be held in late June.

6. Old New Business: Paquette asked the Committee if they will look at the Program’s

current website to see which documents should be placed on the revamped website. She also requested referrals for the upcoming wet season toxicity pesticides study. Helen Fitanides will be at the next Monitoring Committee meeting to discuss the Contra Costa Resource Conservation District’s watershed grants and the work they’re doing in Marsh Creek.

Cousineau and Anne Staines then went through a detailed review of each section in the category, “Broad Audience Outreach; Pollution Prevention Message; Electronic and Print; Coordinate Regionally or County-Wide,” with Committee members. They discussed the outreach opportunities that have been formulated for each category. She requested input from the Committee when appropriate and discussed the potential public outreach strategies of each category.

Page 94: MANAGEMENT COMMITTEE MEETING AGENDA Wednesday, …...Jul 19, 2017  · A. Fiscal Year 2016/17 Municipal Annual Report Packet: Kraai introduced Adrienne Miller from Geosyntec Consultants.

Cousineau explained that Sagent will use the input from this meeting’s discussion and develop a prioritization tool. The tool will feature a rating system for implementation based on whether the outreach tactic meets the minimum MRP requirement, is easy to implement, implementation costs, and the potential short term or long term effect of the tactic.
