Grassy Branch Sees Daylight

Many waterways in Raleigh travel unseen, as does Pigeon House Branch above.  Recent years have seen efforts to rehabilitate – uncover and often “un-straighten” – creeks.  The process is called daylighting.  It helps with flood control and improves the ecosystem.  It happened in Northeast Raleigh last year, and it’s set to happen for Rocky Branch on the NCSU campus(pdf).  So Raleigh has recognized the process as valuable, but it is still an unusual occurrence.  For one Oakwood resident, stymied in efforts to have the city uncover his backyard branch, the benefits were worth the huge personal effort of unearthing the waterway himself by hand.

Chris Crew is a longtime Oakwood resident who co-authored the wonderful Oakwood nature essay I recently featured.  He lives on Elm Street, almost at the bottom of Oakwood’s slope.  Grassy Branch is a small but steady flow that passes under Elm Street and edges his backyard. Until a couple of years ago, it passed unseen in a large buried pipe.

Chris learned of the city daylighting program and tried to get Grassy Branch uncovered.  During heavy rains, the water backed up and even spouted out vertically from broken places in the pipes.  The city couldn’t or wouldn’t do the work because other contiguous neighbors would not enlist their properties.  Tired of the geysers and wanting a healthier backyard creek, Chris decided to do the job himself.  So he and his family hand-dug and wenched out two sections of the 42 inch pipes.

I don’t have pictures of “the dig” – I just heard about Chris’ project recently.  But there is one more section he can remove before Grassy Branch crosses his property line.  I’m hoping he’ll invite me to help, and I’ll be sure to let you know how it goes!

Both Pigeon House and Rocky Branch involve daylighting projects that have or will be addressed in other posts.  An interesting neighborhood daylighting project finished up a couple of years ago near my school, the Fletcher Academy.  The picture below shows the view my students and I have on nature walks at the bottom of Cedar Hills Rotary Park. Three years ago we were looking at the creek disappear into a large pipe.

Today, the adjoining houses have less to fear from flooding, and the biological and geologic interactions missing from pipe existence have been restored to the creek.  One slightly bizarre feature of the project was the city’s purchase and destruction of a house on Mapleridge which sat practically on top of the creek.

Marsh Creek Meanders

Filed under: Nature Lore, Northeast Raleigh, waterways — Tags: , , — raleighnaturalist @ 3:33 pm

   I had the most nature fun OFF the greenway in a long time, searching the headwaters of Marsh Creek.  This prototypical Piedmont creek – running due Southeast and carrying red clay hills down to sandy flats – ends up dumping its large steady flow of water into a huge wetland at the Yonkers Road section of the Beltline – thus its name.  This lower section is full of treats, and will constitute part two of this post.  Recently I browsed through North Raleigh sewer cuts and subdivisions, climbing up Marsh Creek as I did.  My destination – the headwaters – came as a surprise, and emphasized the fascinating cross section of Northeast Raleigh this creek travels through on its way to Crabtree.

   Marsh Creek actually starts just above the blue line showing the creek on this map - at Sutton Square of Falls of the Neuse, its twin springs cradling one of the busiest - and for pedestrians, one of the most dangerous – stretches of four lane in Raleigh. This major creek, which runs for just over five miles from Spring Forest to its intersection with Crabtree, begins on the west side of Falls of the Neuse as a tiny landscaped pond (next to Northbend), and on the east side as the  rocky ditch seen below.

The little brook picks up size quickly as it travels downhill through Northeast Raleigh neighborhoods – alternating older large-lot subdivisions with newer townhouse projects.  It reaches a large natural area just above Old Wake Forest Road, and that’s where I had such fun.  A wide sewer cut gave access to a scrubby but rich haven tucked between neighborhoods, and I was able to see the deer tracks seen at the top of the post, a deer bedroom of crushed broomstraw, cute little coon prints on a sandbank, and a glimpse of a solemn woodchuck, who quickly scrambled into his hole.

Above, a mossy bank just north of Old Wake Forest Road.  Below is the sewer cut, which travels through several acres of undeveloped lowland.

After crossing Atlantic Avenue, where I found another hillside natural area covered with large, iron-rich boulders, the creek parallels that thoroughfare southward for a couple of miles – once again, touching on large older homes and much denser new developments. Before crossing New Hope Church Road it accepts the run-off from Mini-City to the east, and then enters Brentwood.  Here, the creek is the centerpiece of a long, narrow neighborhood park that runs down the center of the venerable and “transitioning” Brentwood subdivision.  It accepts the water from a neighborhood pond on Huntleigh (doubtless called a lake by the residents), and dives under Capital Boulevard, where we will pick it up the next time we visit Marsh Creek.

Raleigh Swamp – Great Nature AT the Beltline

    Raleigh Swamp is the local nickname for this expanse off Raleigh Boulevard. A massive boardwalk with gazebo connects Buckeye Trail with Capital Boulevard.  There are almost always blue herons and/or hawks, dozens of various turtle species, the occasional thirsty deer, and the best chance I know to actually see beavers during the day.  Raleigh Boulevard has become their permanent no-maintenence dam, but their two houses – one on the west bank near the railroad and one right beside the boardwalk – have been badly exposed by the drought.  We will return here often.
