AGENDA ITEM 1.A

DRAFT MINUTES OF A SCHEDULED MEETING

OF THE STORMWATER MANAGEMENT COMMISSION

VILLAGE OF NORTHBROOK

COOK COUNTY, ILLINOIS

MAY 17, 2018

The meeting was called to order at 6:15 P.M. in the Second Floor Conference Room at the Public Works

Center, when a quorum was present.

Members present;

Chairman Thomas Burke

Adele Sturgis

Peter Rosner

Greg Hoeft

Pedro Cevallos

Members absent;

Leonard Rago

Bill Pappas

Craig Hetue

Other staff present: Matt Farmer and recorder Colleen Brunner.

1) Minutes:

On a motion made and seconded, the minutes from the November 16, 2017 meeting were approved as

presented.

2) Hear From the Audience: None.

3) Old Business:

a.) Lake County Homeowners Flood Proofing Expo and Workshop

Farmer spoke with a representative from the Lake County Stormwater Management Commission. They

do not expect the Expo to be an annual event, but they may consider a bi-annual event in the future.

b.) Letter of Map Revision Update

The update for the LOMR is on the Village website. There is a 90 day comment period, which expires

July 20th, concerning technical aspects only. Residents were sent a CRS mailing and a notice published in

the newsletter. Northbrook will maintain its Class 7 rating.

4) New Business

a.) Update of stormwater management projects proposed for construction in 2018

i) Woodlawn Rd- Project 22 & Dehne- Project 25- both projects should start mid-August and be

completed by early November. Village is waiting on final plans.

b.) Update of stormwater management projects proposed for design in 2018

i) Dehne Subdivision- MSMP # 8, Longvalley Drive- MSMP #27, Surrey Lane- MSMP #28,

Willow Creek Subdivision- MSMP #31- All will have an executed contract for design by August. Willow

Creek will have a phase 1 & 2 because it needs to be looked at for expected improvement. The project is

still dependent on property acquisition. The power of attorney for a potential parcel acquisition for

MSMP 31 is aware of the Village’s interest, and an appraisal has been provided. The purchase requires

Board approval.

c.) Creek from Elm Ridge Dr. to Wood Dr.

The design will be done in conjunction with MSMP # 31. The creek has silted in about 2 ft. and

overgrown with small trees and brush. The Village does have an easement but there are issues getting

into the area to dredge it.

d.) Discussion of Private Property Drainage/Flood Protection Cost Participation S.O.P.

A copy of the SOP was included in the packet and was last updated in 2009. The annual budget is

$35,000 with a maximum of $3,500 per participant or 50%, whichever is less. It is on a first come first

served basis with all the funds being spent annually. Currently the resident requests an inspection of their

property and the Village would determine if the drainage issue would qualify for the 50/50 Private

Property Drainage Program. The cost share is 50/50 for any type of construction approved. Village staff

would like to see the existing SOP updated, and Farmer recommends the revised SOP encourage use of

swales, regrading and rain gardens where the water can percolate back into the ground and not enter the

Village’s storm sewer system. He also recommends the requirement of restrictors on all future rear yard

drains that are not installed due to structure flooding. The existing reimbursement rate should be reviewed

and possibly changed (ie:70% for swales, gardens, etc. and 30% for sewer drain projects). Farmer would

like to clarify who qualifies for the program by determining how long the standing water remains on the

property. He recommends that they qualify when the ponding water is still there after 3-4 days.

Sturgis- if a structure was threatened and the best outcome would be installing pipe, she would want to

keep the level of reimbursement at the highest. She felt 3 days of standing water does qualify. Also, the

SOP is 9 years old, so perhaps the reimbursement of $3500 should be increased to account for inflation.

Burke- would agree to reimburse more for more natural remedies.

Rosner- pipe in general is more expensive, so if we limit the reimbursement then is the resident being

penalized? A rain garden still has a pipe underneath that is connected to the sewer.

Hoeft- Perhaps a perc test could be conducted to measure the amount of ground water that is at a property.

This would be a good indication of water levels.

After additional discussion, it was agreed that 3-4 days of standing water is reasonable to qualify and the

70/30 split for reimbursement needs to be further discussed.

5) Next Meeting Date

It was mentioned that President Frum thought the commission needed to meet only twice a year

or on an as needed basis. Sturgis would like to see the commission meet spring, summer and fall when

flooding issues are more prevalent and receive email updates of important issues. She would like to see

the commissioners more involved in the issues that affect the town.

The next meeting will be Tuesday July 12th at 6:00 pm.

6.) Additional Comments

Farmer would like to see better erosion control methods implemented. This will reduce the amount of

sediment entering the Village’s storm sewer and ditches.

For future meetings a line item will be added to the agenda to include “hear from the members/

additional comments”.

On a motion made and seconded the meeting was adjourned at 7:15 p.m.

Respectfully submitted,

Colleen Brunner

Revision Date: April 6, 2007


Revision Date: TBD 2018

Dept.: PUBLIC WORKS Distribution: 1, 2, 3, 5

APPROVAL

Vi lage ngineer

Village Engineer Deputy Village Manager CFO

POLICY: The Public Works Department is responsible for addressingto address inquiries and concerns from property owners regarding rear, side or front yard drainage problems on private property in accordance

with the Village of Northbrook Municipal Code Sections 16-4 and 19-57 and the Village

of Northbrook Standards and Specifications for Public and Private Improvements, Section

IV. These problems are understood to consist of standing (ponding) water and overland

flow of water (drainage), which may or may not endanger inhabited structures.

The use of Village funds will be made available in the Annual Budget, contingent upon

approval by the Board of Trustees, to help improve these situations where everwherever

possible. Such cost participation will be in the form of reimbursement and be set at 50

percent of the lowest bid for the total project cost or a not-to-exceed amount of $3,500.00,

whichever is less. and based on available funding within the budget. It is understood that

one or more private properties may be included and may participateparticipating in a

project. Typical improvements will include storm sewer drainage structures with

connecting storm sewer pipe,: lawn re-grading to establish drainage swales or berms, rain

gardens, rain barrels or the installation of a small flood/retaining wall. In the event that

the problematic drainage area involves multiple properties and/or if there is no means of

correcting the standing water by means of surface drainage (as stated above) the Village

may consider the installation of a storm sewer drainage structure and connecting proposed

storm sewer pipe directly to the Village storm sewer system. Connecting a proposed pipe

system to any existing private system is prohibited unless the property owner can provide

a drainage study showing the existing system can take in additional water without

compromising the original requirements for said system. No Village funding will be

allotted for said drainage study. It will be the responsibility of the participating private

property owners to obtain written permission from all other property owners for any and

all work that occurs on adjacent private properties that are not participating in the project.

PURPOSE: It is the purpose of this Standard Operating Procedure to:

Establish a procedure which includes an expedient investigation of the reported

drainage problem;

Define a uniform methodology to develop and pursue recommendationssuggestions;

and

Provide Village reimbursement cost participating funds to improve said problems,

where everwherever possible.

PROCEDURE:

1. When an inquiry is received from a private property owner regarding a drainage problem, the

Public Works Department will input the inquiry in the Electronic Drainage Investigation

databaseproperty file, indicating the location, name of caller, date, time and general description

of the problem with classification (level) or type of drainage complaint.

1st Flooding basement/crawl space – Response: Day of contact (Immediate response by staff).

2nd Stormwater ponding against residential foundations (no dwelling damage or potential

hazard of flooding building) – Response: Day of or within 24hrs.

3rd Non-structure flooding on property (large amounts of standing water after 72 hrs.) –

Response: 72-96hrs.

4th Downspout/Sump Pump questions – Response: Upon availability of Staffs schedule.

During rain event staff will only be responding to items 1 & 2 where structure damage is

occurring. Residents are always welcome to email pictures to the Public Works Department

showing the water concerns. Call the Public Works Department at 847-272-4711 to get a current

email address.

2. 2. A site inspection by village staff, preferably with the concerned

property owner(s) present, will be

scheduled to better understand the problem. Or permission from property owner to access their

property in the event they cannot be present for site meeting (for non-structure flooding event).

3. 3. The site inspection will attempt to determine if the problem is

caused by a sewer

obstruction, a violation (illegal grading, obstructing landscaping, fences or a misdirected sump

pump discharge or downspout), "“back-pitched"” ground adjacent to the structure, settlement of

ground/lawn areas elsewhere on the property (deficient grading), frost conditions or the absence

of a positive drainage outlet.

4. If the problem appears to be caused by a public sewer obstruction, a Daily Worksheet

iteman internal work order request will be logged increated requesting that the Sewer Crew

jet/flush the line. If the problem appears to be caused by a private sewer obstruction, the apparent

owner of the private sewer will be notified of the problem in writing with a request to repair.

5. If the problem appears to be caused by a violation, and if the violation is causing personal

property damage to a dwelling the violator will then be notified in

writing to request that the violation be correctedand must resolve within thirtyten (10) calendar

days. of the dated letter. If the violation remains outstanding after thirtyten (10) calendar days, on

the next business day a second letter will be sent requesting compliance within ten five (5)

additional calendar days. If the violation has not been corrected after this time, a third and final

certified letter will be sent requesting compliance within five days. If the violation still has not

been corrected by date specified in the third and final letter,and the matter will then be referred to

the Second Municipal District Court and a citation will be delivered by the Police

Department.USPS Certified and regular mail from the Village Staff. It will be at the discretion of

the Village Engineer to increase the time duration between notices if in climateinclement weather

conditions exist. Village Staff will track all communications in the property file.

6. If the problem appears to be caused by a new or recently completed construction

project (Building Permit), the matter will be referred to the Building & Development Department

for resolution.

7. If the problem is caused by deficient grading and/or the absence of a positive drainage

outlet, the Public Works Department will provide in writingmake a "concept" (preliminary) plan

indicatingsite visit and offer verbal suggestions on how to remedy the general

recommendation(s)concern. The home owner should also consult with contractors to find other

possible remedies and then consult with the Village on their decision to improve the situation in

accordance with Village standardsStandards. The recommendation(s)suggestions will typically

consist of the construction of a drainage swale and/or, berms, the installation of a drainage

structure with connecting storm sewer pipe, rain gardens, rain barrels, a small flood/retaining wall

or any combination of these based on the site conditions.

7.8. In the event the problematic area involves multiple properties and/or no means of correcting the

standing water by means of surface drainage (as stated above) the Village may consider the

installation of private storm sewer drainage structures and connecting storm sewer pipe to the

Village storm sewer system including a permanent 2 ½ inch restrictor prior to entering the

Village system. In accordance with the stipulations of Section 8below of this SOP, the property

owner(s) can then undertake these recommendation(s)suggestions in order to improve the

drainage problem, if desired with Village reimbursement cost participation, which will be

dependantdependent upon available budgeted funds and approval by Village staff if qualifying

for this program.

8.9. If the property owner(s) desires to pursuemove forward with improving the recommendation(s)

to improve the

drainage problemconcern, a minimum of three (3)comparable bids from private contractors must

be obtained by the property owner to construct the recommendation(s)- indicated onagreed upon

solution between the concept plan.homeowner and the Village. If three bids can not be obtained

by the property owner(s),, it will be at the discretion of the Village Engineer to accept only two

bids. No projects will be considered if only one bid is submitted. Be advised that the

concepthome owner’s suggested plan may need to be refined in order to address specific site

conditions, which will be the responsibility of the selected contractor or other property owner(s)

representative.

for the property within 60 days as approved by Village Staff, the property owner will forfeit

their opportunity to qualify for Village funding for that budget year and will be eligible for

funding the following budget year with the understanding the Village may not be offering the

option of installation of private storm sewers in future Village budget.

13. The property owner must contact the Development and Planning Department at 847-664-4050 to

obtain the permit to start the work and to schedule all required inspections, and Public Works at

847-272-4711 to receive final approval of the completed drainage improvements; and provide

accordance with Village Standards. The suggestions will typically consist of the construction of

a drainage swale, berms, rain gardens, rain barrels, a small flood/retaining wall or any

combination of these based on the site conditions.

8. In the event the problematic area involves multiple properties and/or no means of correcting the

standing water by means of surface drainage (as stated above) the Village may consider the

installation of private storm sewer drainage structures and connecting storm sewer pipe to the

Village storm sewer system including a permanent 2 ½ inch restrictor prior to entering the

Village system. In accordance with the stipulations below of this SOP, the property owner can

then undertake these suggestions in order to improve the drainage problem, if desired with

Village reimbursement cost participation, which will be dependent upon available budgeted

funds and approval by Village staff if qualifying for this program.

9. If the property owner desires to move forward with improving the drainage concern, a

minimum of three comparable bids from private contractors must be obtained by the property

owner to construct the agreed upon solution between the homeowner and the Village. If three

bids can not be obtained by the property owner, it will be at the discretion of the Village

Engineer to accept only two bids. No projects will be considered if only one bid is submitted.

Be advised that the home owner’s suggested plan may need to be refined in order to address

specific site conditions, which will be the responsibility of the selected contractor or other

property owner representative.

The three contractor bids along with the concept plan will need to be submitted to the Public

Works Department for review and approval. If the plan does not meet Village requirements

review comments will be provided. This is necessary to ensure that all work and materials

conform to Village standards. If the property owner desires to utilize a contractor that is not the

to release the reimbursement check. Reimbursement is based on lowest bid. The

reimbursement funds will be paid out on a “first come first serve” basis and the total amount

available may vary from year to year.

10. All correspondence pertaining to the inquiry, including the preparation or implementation of

any plan supplied by the property owner, private contractor bids and reimbursement

information will be filed in the Village’s Property Address database.

11. Property owner appeals of staff suggestions and cost participation amounts are to be heard by

the Village’s Stormwater Management Commission. The Stormwater Management

Commission will make every attempt to resolve the points of contention. If unable to resolve

the issue, the matter may proceed to the Village Board along with the Commission’s

suggestions.

12. If the property owner decides not to move forward with suggestions for drainage

improvements for the property within 60 days as approved by Village Staff, the property

owner will forfeit their opportunity to qualify for Village funding for that budget year and will

be eligible for funding the following budget year with the understanding the Village may not

be offering the option of installation of private storm sewers in future Village budget.

13. The property owner must contact the Development and Planning Department at 847-664-4050

to obtain the permit to start the work and to schedule all required inspections, and Public

Works at 847-272-4711 to receive final approval of the completed drainage improvements;

cost associated with the installation of said drainage improvements.

14. The Village shall make reimbursement payments to Property Owners only, not to contractors

or suppliers. Payment requests will follow the procedures outlined in the Village’s Standard

Operation Procedure “FI-30-007 Payment of Invoices”. The resident will need to fill out and

submit the W-9 form to the finance department to receive their reimbursement check.

15. Any storm system installed using this program, including but not limited to underground pipe

and drain, swales, lot grading, raingarden, rain barrels or any other system, is the private storm

system of the resident on whose property it is installed and must be maintained by that

property owner and any future property owner of the property.

16. In the event there is a substantial improvement to the property (SFR, SFRAD, Patio,

Swimming Pool, etc.) that will require the installation of drainage or private storm sewer

improvements within a five year period following the date of reimbursement by the Village for

cost participation funds; a refund by the property owner shall be required. The property owner

refund shall be 100% of the Village’s cost participation within one year of payment, 80% for

the second year, 60% for the third year, 40% for the fourth year and 20% for the fifth year

Village of Northbrook Memo re: Green Infrastructure Program

TO: Stormwater Commission

FROM: Matt Farmer, Village Engineer

DATE: September 20, 2018

SUBJECT: Green Infrastructure Program – Board of Trustees Referred Item

At the June 12th Village Board of Trustees meeting a resident requested the Village consider the use of Green Infrastructure in the parkways in the form of stormwater absorbent soils and vegetation. The topic of a Green Infrastructure Program was referred to the Stormwater Commission for its review and recommendation by President Frum. The video of the meeting can be viewed on the Village website from minute marker 12:30 to 18:30. With that, questions for the Commission to consider regarding the topic of Parkway Green Infrastructure include: 1. What additional information does the Commission need as it further considers the topic? 2. Are there any outside experts the Commission may request presentations from on the topic? 3. Would information from other communities who have implemented such practices be helpful?

Hi Sandy,

I am planning to attend the Village Board meeting this evening. I want to propose the Village start a Green Infrastructure Programto better manage the increasing rain we have been experiencing. Stormwater is forecast to greatly increase with rising globaltemperatures and humidity. This stormwater can't all be pushed into communities downstream like we have been doing.

I have re-landscaped my parkway and front yard with water absorbing ground cover/soil that is very attractive. And, we are seeingmore and more road medians converted to these kind of ground covers. They greatly reduce the maintenance needed for typical turfgrass medians and parkways. My parkway and front yard needs only one cutting a year. It does require physical weeding andwatering while it is getting established but then the ground cover keeps most of the weeds out.

There are many parkways that could be planted with ground covers such as along Pfingsten Road that are fenced off fromhomes. The home owners in my neighborhood tell my my parkway is beautiful and would probably love the Village to replace turfgrass with ground cover, especially where tree roots are exposed above the grass. Terry Cichocki has a list of many appropriateplants. My home could provide a model for other home owners as well as the Village. I would be glad to help.

I suspect this kind of program would fit best under Jeremy Reynolds - EQC. The Stormwater Commission is focused on engineeringconcrete and ditches. They don't have experience with plants or soil ecosystems that are needed to absorb stormwater.

I sent this to explanation to Rich Nahrstadt yesterday. Now I have time to attend the Board meeting tonight. See you then.

Thanks for your analysis of miles of roads in Northbrook. Using these numbers we calculate that Northbrook has 158miles of roads (i.e., local, county and state). This is equivalent to 158 miles X 5280 feet/mile = 834,000 feet of roadway.

We then estimate that the average Northbrook road "parkway" is between 5 and 10 feet on each side of the road, or10 - 20 feet width on both sides along the entire road system. Thus, the parkway area in Northbrook is between 8and 17 million square feet of space.

Using a rough estimation that 1 inch of rainfall is equivalent to about 1/2 gallon/square foot, we estimate the gallons ofstormwater that can be absorbed by healthy soil and its plant/animal ecosystems in our parkways is between 4and 9 million gallons of stormwater per inch of rainfall. Double that for a 2” rainfall that is becoming much morecommon. That is a lot of water to be absorbed by plants that clean the air and water, and cool the homes andneighborhoods through nature’s air conditioning system. And, it is significantly cheaper that burying biggersewers and water retention areas with their mosquito breeding potential.

But, the amount of stomwater absorbed is completely dependent on the health and openness of the soil. Lots of decayingplant material left on the soil (i.e., not taken “away”) restores the minerals used up by plants and provides a healthyhabitat for the fungus, bacteria and bugs to aerate the soil. This process creates tunnels and holding areas forstormwater. Once established this process, unlike impermeable concrete tunnels and tanks, leaves continually open soilspace that never “fills up” with water. The natural water absorption process is continual in a healthy ecosystem.

If the soil is compacted by frequent mowing or application of high salt fertilizers, winter salts, or toxins like glyphosates,neonicotinoids or Roundup type chemicals that kill plants and soil life, very little stormwater is absorbed. This is what usually happenswith turf grass yards. The frequent traditional turf “maintenance” programs create an impermeable water barrier. Thus, the Villagedesire to increase the frequency of lawn mowing in order to create a “controlled look” of an English turf-grass estate reduces waterabsorption, and increases Village flooding.

Ground covers offer home owners and the Village an opportunity to reduce soil compaction and the use of toxicchemicals. Ground covers can be used to create a fine textured, very attractive landscape that reduces Village flooding.They should be promoted as an alternative to a Village mandated frequent lawn cutting program with its high noise, andits air, soil and water pollution impacts.

Go Green Northbrook suggests that the Village of Northbrook create “best-practice” examples of parkway groundcovers(i.e., "Green Infrastructure") for home owners. The Village could promote the use of ground covers by circulating picturesof my and other front yard best practices in the Village Newsletter. The Village could also request they be notified aboutother "Green Infrastructure" best practices around the Village. These kind of “Stormwater Best Practices” should bepublicly recognized by the Village.

Go Green Northbrook is willing to provide assistance for this kind of program.

Someone would need to do a pretty detailed GIS analysis to figure out our areas of parkways.

I did some quick measurements on the mapping portal and came up with

· 12.9 miles of county roads in Northbrook, and

· 15.1 miles of IDOT roads.

I did not count the Edens or tollways.

Hi Tom, Matt, Kelly & Eric,

Does the Village have an estimate of the parkway space along roads in Northbrook? I would like to know more abouthow much parkway space we have in Northbrook to estimate the amount of area available to absorb stormwater withgreen infrastructure. The parkways I have seen vary in width from 0’ downtown to over 30 feet on some of our suburbanroads. Some parkways are fenced off from neighboring homes, some are an extension of the front yard. If Tom’sestimate of 130 miles of local roads is accurate, how many miles are there of state and county roads in our Village?

My architect/landscape architect/urban planners (Joel & Camille Stauber) calculate that one inch of rainfall is equivalentto ½ gallon of water per square foot of ground. My home parkway (i.e., 2966 Stonegate Lane) is 10’ wide X 70 feet long.Including my neighbor across the street this totals 1400 SF of parkway. The road in front of my house is about 84’ long.Based on this math, my neighbors and I together will each receive 700 gallons of water for each 1” of rain on our 1400square foot parkways. The rains of yesterday, June 8th, brought at least 2" of rain. Holding the water on the parkwaysand out of the sewer runoff that causes flooding seems pretty important.

Working with my landscape architect, we have changed our hard clay soil into soft absorbent soil that does not shed therainwater, or contribute to flooding with attractive groundcover plantings and a sustainable maintenance program. Myneighbors are pleased with my landscape. I believe that this approach to parkways can help our community on severalfronts. Please come over and check out the landscaping. The Heuchara was just planted in the front yard June 4. TheSedem was planted in the parkways in April 2016.

I would appreciate any estimates you have of parkway space so I can estimate the impact of this approach. Of course, thisis something to be tested and further evaluated to insure attractive and manageable outcomes. Could we discuss how theVillage can implement this kind of program?

Doug,

I found information on the PW website under street maintenance saying we maintain about 130 miles of roads – but I believe thiswould exclude all of the State and County roads.

I recall this being something that Public Works tracked, but do not see it on our website.

I will see what I can find.

Subject: miles of roads in Northbrook?

Hi Tom,

How do I find an estimate of the miles of roads (e.g., state, and local arterials + local roads) in Northbrook?

I want to propose a conversion of the turf grass in these road parkways and medians to ground covers that willdecrease maintenance costs (e.g, mowing, fertilizing and herbiciding by the village or home owner). Thisconversion to ground covers will also greatly increase stormwater absorption with the ground-cover type plantsand soils, (turf grass absorbs very little stormwater), and increase the environmental support for butterflies,pollinators, birds and other native insects.

This conversion of turf grass to ground cover is happening around the state and country (e.g., Willow Roadthru Northfield) and could be used by Northbrook. This process would also create a new "best landscapepractice" for home owners who are tired of cutting, watering and herbiciding their lawns, and are willing to sendtheir kids - grandkids to Village turf-grassed parks to play sports.

It could also be used to absorb huge amounts of stormwater that the Village is currently trying to senddownstream to other communities, instead of trying to absorb in our soils and in plants for local use duringdroughts. Northbrook is currently spending thousands of dollars on new sewers, a huge waste of money thatcould be used on re-landscaping to improve nature's Green-absorption processes. We need planners andlandscapers who know what they are doing to replace engineers focused on controlling nature with expensivepipes and soil excavations.
