(563) 556-2464 (563) 556-7811 (Fax)

IIW, P.C. has been asked to complete an application for the City of Dyersville for the Iowa Department of Natural

Resources (IDNR) Clean Water State Revolving Fund (CWSRF) Water Resource Restoration Sponsored Projects.

The City of Dyersville and IIW have received assistance during the application process from Eric Schmechel from the

Dubuque Soil & Water Conservation District. The following information addresses the requirements identified in the

Application Completeness Checklist.

Assessment of the impacted waterbody and its watershed with data that supports the identification of the

water quality problems to be addressed

Both Bear Creek and the North Fork Maquoketa River are within the City of Dyersville and included on Iowa’s

303(d) list of impaired waters. Bear Creek is listed with the cause of impairment being “Fish Kill Caused by

Ammonia”. TMDL Status is listed as “TMDL needed.” Bear Creek is also on the 305(b) list of Assessed Waters

with a designated use of Aquatic Life Support for Fish, Shellfish and Wildlife Protection and Propagation that is

listed as impaired. A presumed designation of Primary Recreation has not been assessed. Causes of

impairment for reporting year 2012 are listed as “Ammonia, Un-ionized” and “Organic Enrichment/Low Dissolved

Oxygen,” each for a designated use of Aquatic Life Support.

The North Fork Maquoketa River downstream of the confluence with Bear Creek is on the 303(d) list of impaired

waters with causes of impairments “Cause Unknown (Biological): Mussels, and Cause Unknown – Biological

Integrity”. The North Fork upstream and downstream of the confluence are on the 305(b) list of Assessed Waters

with a designated uses of Aquatic Life Support, Fish Consumption and Primary Recreation. Aquatic Life Support

is listed as impaired the same as Bear Creek.

In 2006, the Iowa DNR published “Stressor Identification – North Fork Maquoketa River, Iowa”, for the North

Fork Maquoketa River (Segment No. IA 01-NMQ-0020_2) and Hickory Creek (IA 01-NMQ-0160). This TMDL

found sufficient evidence to identify the primary stressors to the stream as follows:

Lethal concentrations of un-ionized ammonia

Elevated levels of total suspended solids and turbidity

Elevated levels of silt accumulation and sedimentation of rock substrates

Low / potentially lethal levels of dissolved oxygen and extreme fluctuations in dissolved oxygen levels

Excessive growth of benthic algae

Nonpoint source contributions to water quality concerns include:

Urban storm water carrying road and parking lot related pollutants such as sediment, heavy metals, oils,

salts, etc.

Soil erosion from degraded stream banks and open soils throughout the watershed.

Discussion of project goals and objectives

The broadest goal of the CWSRF program is to improve water quality in the streams of Iowa, especially those

that are 303(d) listed. That same goal applies to the City of Dyersville with respect to the North Fork Maquoketa

River and Bear Creek, together with a more long-term goal of education and awareness of watershed and storm

water impact issues. More focused objectives involve maximizing the impact of the funds available through the

CWSRF program. The main objectives for the project are as follows:

Establish a working relationship with local district and watershed conservationists, the Iowa Department of

Natural Resources, and the Iowa Department of Agriculture and Land Stewardship; so in the future BMPs

might continue to be incorporated in future public and private improvement projects in the City of Dyersville.

Improve the water quality of the North Fork Maquoketa River and Bear Creek by positively impacting storm

water runoff through a variety of BMP treatment measures strategically and thoughtfully selected to address

specific conditions throughout the watershed.

Increase enjoyment of public recreational areas along the streams and increase public awareness of

watershed and storm water issues.

The measures that are identified in this application will provide improvement to stormwater quality through

reductions in total suspended solids and nutrients.

Evaluation of possible water quality practices that could be implemented, considering the unique

demographic, topographic, hydrologic, and institutional characteristics of the planning area

IIW, P.C., together with Eric Schmechel, conducted a windshield survey and identified a variety of BMPs that could

be implemented to work toward achieving the project objectives stated above. Exhibit A, “EX A, Potential BMP

Locations,” has been prepared and attached to indicate some of the ideas that were produced during the

windshield survey and approximate locations. The proposed Nonpoint Source (NPS) control BMPs include:

NPS Control Green Infrastructure Measures (Category VI-C)

Restoration of Riparian Buffers (stream buffers)

Soil Quality Restoration (increased infiltration)

Infiltration / Bioretention Basins (including snowmelt capture from snow storage areas)

Enhanced Dry Swales

Permeable Pavements

Convert green space to native prairie

NPS Control, Agricultural Cropland (Category VII-A)

Cover Crop Program

Stream Buffers

NPS Control, Hydromodification (Category VII-K)

Repair of streambank erosion in selected areas.

The City of Dyersville proposes to use at least 80% of any awarded funds toward Grean Infrastructure and

Hydromodification Measures within the City Limits, preferably near public use areas, in an effort to enhance the

public awareness and educational aspects of the project.

Additional preliminary design and calculation efforts together with field visits with project resource personnel

would be accomplished prior to final development of plans for construction and implementation. This will allow

for a collaborative evaluation.

Description of potential practices to be implemented with the expected water quality outcomes

Category VI-C, Green Infrastructure BMPs

Restoration of Riparian Buffers would be combined with Stream Bank Restoration (Category VII-K,

Hydromodification) at selected locations along Bear Creek and the North Fork Maquoketa River near the

confluence with Bear Creek. Stream bank restoration may consist of restoration of riparian corridor with low and

wide banks combined with appropriate vegetation to resist erosion. In some areas, it is expected that rip-rap or

other hard armoring may be appropriate to stop erosion and imminent bank failures. These measures will result

in reduction of significant amounts of sediment being deposited directly into the stream as well as better

performance with less erosion during high flows. Stream Bank Restoration would be accomplished in

accordance with NRCS Conservation Practice Standard 580.

Soil Quality Restoration could be used anywhere and combined with other BMPs such as enhanced dry swales,

bio-retention or infiltration basins, and restoring native prairie. SQR will increase infiltration and decrease or

eliminate the need for fertilizers. SQR would be most effective in places that receive some runoff from

impervious surfaces because they would help counteract the impact of the impervious area by increasing the

rainwater storage capacity of the soils and increasing infiltration into the subsoil. SQR will be conducted in

accordance with Section 2E-5 of the Iowa Stormwater Management Manual. SQR has been estimated to

remove up to 59% of TSS, 5% of Total Phosphorus, and 46% of Total Nitrogen over typical compact turf.

Infiltration and Bio-retention basins or cells could be located anywhere that receives runoff from impervious

surfaces. For locations that produce a significant sediment load (for example the snow storage areas), a buffer

strip should be used to prevent clogging of the filter soil matrix. These BMPs could be applied alongside parking

lots, paved or unpaved or alongside 3rd Street (the portion with no curb & gutter) in conjunction with enhanced

dry swales for conveyance. There is also a possibility that a longer and narrower version of bio-retention could

be used for some of the urban section street with curb & gutter by creating a depressed strip between the street

and the sidewalk just upstream of an existing intake. Several possible locations were noted along 3rd Avenue for

example. Bio-Retention cells will be designed in accordance with Section 2E-4 of the Iowa Stormwater

Management Manual. They have been reported to remove up to 59% of TSS, 5% of Total Phosphorus and 46%

of Total Nitrogen loads.

Enhanced Dry Swales could be applied alongside 3rd Street between the street and the soccer field. This would

help convey storm water from 3rd Street, the section which has no curb & gutter, toward the Bear Creek while

providing an opportunity for sediment to settle out and nutrients to be taken up by vegetation. The swales could

also be used in combination with SQR and a reasonable selection of native grasses that would be compatible

with the adjacent recreational uses while helping to further increase infiltration and potentially reducing

maintenance requirements (mowing). Swales will be design and constructed in accordance with Section 2I-2 of

the Iowa Stormwater Management Manual. The potential for removal of TSS and nutrients are dependent on the

length of the swale with respect to its tributary area, but conservative estimates could be as high as 50% for

TSS, 25% for Total Phosphorus, and 20% for Total Nitrogen.

Permeable Pavements could potentially be beneficial for a few locations that currently have gravel parking.

These locations may be appropriate for a lower cost version of permeable pavements such as a “Grass-Pave” or

“Gravel-Pave” type of product. These products help strengthen the turf and gravel while maintaining a higher

degree of infiltration capability than typical compacted subgrade and base stone surfacing.

Converting green space to native prairie could be used to help promote infiltration and reduce maintenance, but

one of the bigger impacts could be the publicity and educational benefit. With a properly sized and located patch

of land, a native prairie could be a beneficial amenity in the area of the public parkland. It offers an opportunity

for residents to see firsthand the kind of wildflowers, plants, and grasses that are beneficial to the watershed by

helping to restore infiltration and increase nutrient uptake. Part of this effort could also include informational

signage to enhance the educational aspect.

Category VII-A, Agricultural Cropland BMPs

The City of Dyersville understands that significant positive impacts can be made to stream water quality by

working with agricultural land further up in the watershed. With this in mind, up to 20% of the funds that may be

awarded to this proposal would be allocated to Category VII-A BMPs. These BMPs would require cooperation

with the Dubuque Soil & Water Conservation District and would likely implement a cost sharing scheme that

would need to be further defined.

Cover crops have several benefits including reductions in soil erosion and increase in organic content of the soil

which increases infiltration. Cover crops have been estimated to reduce phosphorus load by 50% and nitrogen

load by 28% when conducted over the long-term. Cover crops as part of this CWSRF project would be done in

accordance with NRCS Conservation Practice Standard 340.

Stream buffers of vegetative filter strips are also a likely candidate for agricultural land BMPs, but more field

reconnaissance would be needed before proposing any possible locations, and landowners would need to be in

support of the project and willing to grant an easement. Use of vegetative filter strips would be done in

accordance with the NRCS Conservation Practice Standard 393 as an edge of field practice alongside

streambanks.

Discussion of project locations, land ownership, and any plans for acquiring properties or easements

As shown on exhibit EX A, several locations have been identified for the placement of BMPs. All locations shown

are on City-owned property, and city ownership will be one of the criteria used for the final selection of BMPs.

Initial preliminary design and a field visit with project stakeholders will be utilized to determine the most impactful

and viable locations.

For agricultural BMPs, all the land would be privately held, so the landowners would need to be willing to

participate in the program and work with the project to establish any easements or rights of entry needed to

accomplish the work. The proposed budget in Section 6 of the application form has an allocation for

land/easement acquisition.

Identification of any other organizations or resources to be involved in the project and their expected

contributions

As a part of the application process, design phase, and the construction phase of the project, the City and IIW,

P.C. will be receiving assistance from Eric Schmechel with the Dubuque Soil & Water Conservation District. Eric

may also choose to enlist further assistance from the local NRCS office. The City and IIW, P.C. have had

meetings and conference calls to discuss the proposed projects and the application for the CWSRF Sponsored

Project.

Proposed project schedule with major milestones, along with a discussion of how the sponsored project

construction schedule coordinates with the infrastructure project schedule

The proposed improvements would be constructed concurrently with the City of Dyersville’s Wastewater

Treatment Facility (WWTF) Phase 3 Expansion and Southeast Collection System Diversion projects. The

construction of the WWTF and Southeast Collection System Diversion improvements are planned to commence

sometime in late summer or early fall 2015, extending into spring of 2017. See below for the proposed schedule

for the CWSRF Sponsored Project for the City of Dyersville.

Proposed evaluation procedures and measures

There are several goals that the City would like to achieve with the CWSRF Sponsored Project as discussed

previously. Locations and types of BMPs will be evaluated so that the goals of the City can be met as a part of

the project. The following are the evaluation procedures that will be used when determining what BMPs will be

installed in specific locations:

1. Has the stream bank been stabilized?

Initially, a simple before-and-after observation of the work accomplished will go a long way toward

answering this question. Additional observations will be made after significant flow events (10-yr to 100-yr

recurrence interval storms) to verify stream bank stability.

2. Have the City and its residents experienced increased enjoyment of the area and are they more aware of

watershed and storm water issues?

This question could be answered by means of a community poll or questionnaire.

3. Has the water quality from the storm runoff been affected positively by the BMPs implementation?

Given the size of the overall watershed relative to that of the proposed BMPs, a numeric analysis of water

quality in the main stream before and after these improvements would not seem to yield a discernable

result. Instead, measurements could be taken at each installed BMP that could provide a reading of the

amount of total suspended solids captured by that BMP. We proposed to develop a scheme for such

measurements during design and in collaboration with our technical resources.

Explanation of the proposed budget, including other planned funding sources and flexibility to adjust budget

according to final amount available through the sponsored project mechanism

If BMPs are to be implemented at all possible locations within the vicinity of the public park in the City of

Dyersville, as shown on exhibit EX A, the cost could easily exceed the funding available through the CWSRF

program. Therefore, the locations and extents of each of the proposed BMPs will be evaluated based on a cost-

benefit approach that considers all the objectives previously stated. A table outlining possible costs of

implementing BMPs at the indicated locations is included below in Figure 2.

The City is not proposing to utilize any other funds for the proposed sponsored project other than the amount of

forgone interest associated with the CWSRF loans for the proposed wastewater projects. The extent of the

proposed sponsored project improvements would be selected as to not exceed the funds that the City would

receive through the CWSRF sponsored project program. Itemized costs for the proposed sponsored project

assuming the maximum award have been tabulated in Section 6 of the application form.
